Abstract Aim Prophylactic surgical extraction of impacted third molars is a common practice throughout the world justified on the presumption that the risk of surgical morbidity increases with increasing age, among other reasons. The aim of this study was to analyze and compare surgical morbidity associated with third-molar extractions in young and aging populations. Methods and Materials A review of records for all patients who underwent the surgical extraction of impacted third molars between April 2001 and June 2006 at the Lagos University Teaching Hospital was carried out. Results A total of 506 patients had surgical extractions of impacted third molars under local anaesthesia during the period of the study. Of these, 470 (92.9 percent) patients were below the age of 40 years (Group A) and 36 (7.1 percent) patients were 40 years of age and older (Group B). No incidences of severe intraoperative complications (excessive bleeding or mandibular fractures) were recorded in either group, but other postoperative complications were reported in 70 (13.8 percent) patients. Of these 70 patients, 65 (92.9 percent) were from Group A and 5 (7.1 percent) were from Group B, and their complications included infected socket, dry socket, paraesthesia, and buccal space abscess. Conclusions No significant difference in postoperative complications following surgical removal of mandibular third molars was found between patients 40 years old and greater and those below age 40. Prophylactic surgical extraction of impacted mandibular third molars, based on the assumption that surgical morbidity increases with age, may not be justifiable. Clinical Significance Age does not predispose patients who had surgical extraction of mandibular third molars above 40 years of age to any additional surgical complications when compared to patients below the age of 40 years receiving comparable treatment.

ABSTRACT Background Third molars are one of the most commonly impacted teeth in the oral cavity. But in very rare cases, the impacted molars can be inverted as well. In this case, the patient presented with an inverted and impacted left maxillary third molar. The aim of the operating surgeon was to execute the procedure in the least hazardous manner, to avoid any surgical complications. Methods The surgical extraction of the tooth by lateral transposition method was carried out rather than the classical method owing to the inverted position of the impacted tooth. The surgery was carried out under local anesthesia. An incision was made at the crest of the ridge with an anterior releasing incision. Bone overlying the impacted molar was removed following which the tooth was luxated and laterally transposed. The socket was thoroughly irrigated and closure was done by simple interrupted suture, using 3-0 mersilk. Results The impacted and inverted maxillary third molar was successfully removed by lateral transposition method without any complications. Conclusion The impacted and inverted maxillary third molars are not commonly encountered in dental practice. Subsequently, their removal can be a challenging job on the part of an oral surgeon. The surgeon should preoperatively weigh carefully the associated risk factors and explain them thoroughly to the patient. How to cite this article Chhabra S, Chhabra N, Dhillon G.

Full textAbstract:
Extraction of third molars is the most common surgical procedure performed in oral surgery on a daily basis and, despite surgical skills and expertise, complications may occur. Complications observed during or after third molar removal may include pain, swelling, bleeding, infection, sinus perforation and nerve damage. Fortunately, with a proper management and a good surgical technique, the incidence of such events is low. Subcutaneous emphysema associated with dental extraction occurs when the air from the high-speed dental handpiece is forced into the soft tissue through the reflected flap and invades the adjacent tissues, leading to swelling, crepitus on palpation and occasionally spreading through the tissue spaces of the fascial planes. Although rare, iatrogenic subcutaneous emphysema can have serious and potentially life-threatening consequences. Care should be taken when using air-driven handpieces. The access of air into the facial tissues is not limited to tooth extractions, but may also occur through other portals of entrance, such as endodontically treated teeth, periodontium and lacerations of intraoral soft tissues. When subcutaneous emphysema occurs, it must be quickly diagnosed and properly managed to reduce the risk of further complications. This report presents a case of subcutaneous emphysema occurred during extraction of a mandibular third molar extraction with the use of an air turbine handpiece. Case management is described and issues relative to the diagnosis and prevention of this surgical complication are discussed.

The removal of impacted maxillary third molars is one of the most common procedures performed in oral and maxillofacial surgery units with low rates of complications and morbidity. A few cases of accidental displacement of third molars into adjacent anatomical spaces, such as the infratemporal fossa, the pterygomandibular space, the maxillary sinus, buccal space, or the lateral pharyngeal space, during surgical interventions have been reported. In this paper, a case of a maxillary third molar accidentally displaced into the pterygopalatine fossa is presented, and the removal of the tooth via intraoral approach is described.

Objectives. The comparative evaluation of the role and information contribution brought by panoramic radiography (X-ray) and CT to the preoperative assessment of third molars, found in different stages of eruption. This assessment is useful both for certifying the diagnosis and for establishing the proper surgical strategy adapted to specific clinical cases, in order to avoid undesirable surgical incidents and postoperative complications. Patients and method. This is a retrospective study in which 23 patients were enrolled, on whom 79 third molars were identified. All these molars had, for various (historical and clinical) reasons, removal indications. Sex distribution of the patients was: 6 (26%) men and 17 (74%) women. After a detailed clinical examination, a digital panoramic radiography was performed on all patients, which provided additional useful information. This imaging investigation allowed a sorting out of the cases in which an additional preoperative imaging investigation, such as CT, was required. CT information was compared with that obtained from panoramic radiography (X-ray) and surgery intervention data. Results. In this study imaging investigation was performed on 79 third molars: 41 (51.9%) on upper third molars and 38 (48.1%) on lower molars. As concerning the stage of impaction, 22 (27.84%) were impacted and the same percent was found for those partially impacted. In 22.5 (28.48%) cases root dilacerations were identified. Special attention has been granted to the anatomical relationship of third molar roots with nearby structures: maxillary sinuses and the mandibular canal. So, from the upper third molars, 13 (31.7%) were in the sinus and so were those which were in close relationship with the sinus. Conclusion. Panoramic radiography (X-ray) provides orientative and often insufficient information about root morphology and anatomical relationships of third molars. In the clinical cases which required a comprehensive imaging assessment, CT data were crucial for adapting surgical procedures to specific clinical situations, minimizing surgical incidents and postoperative complications. Discerning recourse to 3D imaging ensures net benefits for patients as well as for dental practitioners.

Introduction: Impacted third molars (ITMs) surgery, is one of the most common methods in the field of oral and maxillofacial surgical operations. Administration of corticosteroid such as dexamethasone diminishes the postoperative sequelae. The study aimed to compare the impact of dexamethasone administration on pre-operative and post-operative complications in third molar surgery. Methods: We collected all randomized controlled trial data on the influences of pre-operative and postoperative dexamethasone administration between 2006-2019 on third molar surgery sequelae by searching the keywords: dexamethasone, third molar surgery, wisdom teeth, corticosteroids, oral surgery, maxillofacial surgery, preoperative, postoperative, pain, swelling, and trismus in international databases such as: Web of Science (ISI), PubMed, Scopus, Embase and Cochrane Library. Results: Twenty-three articles were included in this narrative review. Among them, 22 studies used dexamethasone in particular and 1 study used dexamethasone with amoxicillin. Twenty studies evaluated the prescription of dexamethasone in pre-operative and post-operative routes on pain, trismus and edema following third molars operation. Five studies administered dexamethasone postoperatively and 15 studies administered the drug preoperatively. Two studies evaluated the preoperative and postoperative administration method. Fourteen studies used a 4 mg dexamethasone dose and drug administration was variable. The treatment period in postoperative studies varied between 1 to 7 days. Conclusion: Dexamethasone appears to be a promising agent in in reduction of post-operative complications following third molar surgery. As a potent anti-inflammatory agent, it has an effective role in pain, trismus and edema reduction distinguished from the routes of administration, dosage and timing, pre or postoperative prescription.

Background and Objectives: Coronectomy is a relatively new method to prevent the risk of Inferior Alveolar Nerve (IAN) injury during removal of lower third molars with limited scientific literature among Nepalese patients. Thus, a study was designed to evaluate coronectomy regarding its use, outcomes and complications.Materials and Methods: A descriptive study was conducted from December 2012 to December 2013 among patients attending Department of Oral and Maxillofacial Surgery, College of Dental Sciences, BP Koirala Institute of Health Sciences, Dharan, Nepal for removal of mandibular third molars. After reviewing the radiograph for proximity of third molar to the IAN, coronectomy was advised. A written informed consent was obtained from the patients and coronectomy was performed. Patients were recalled after one week. The outcome measures in the follow-up visit were primary healing, pain, infection, dry socket, root exposure and IAN injury. The prevalence of IAN proximity of lower third molars and incidence of complications were calculated.Results: A total 300 mandibular third molars were extracted in 278 patients during the study period. Out of 300 impacted mandibular third molar, 41 (13.7%) showed close proximity to inferior alveolar nerve . The incidence of complications and failed procedure was 7.4% among the patients who underwent coronectomy. During the follow up visit, persistent pain and root exposure was reported while other complications like inferior alveolar nerve injury, dry socket and infection was not experienced by the study patients.Conclusion: With a success rate of 92.6% among the 41 patients, coronectomy is a viable alternative to conventional total extraction for mandibular third molars who have a higher risk for damage to the inferior alveolar nerve.JCMS Nepal. 2015;11(3):1-5.

Neurosensory deficit is a well-reported complication after lower third molar surgery. It is useful to know the outcomes of the available treatments for neurosensory deficit after third molar surgery. It is more important to prevent nerve injury from third molar surgery. This thesis aims1) to evaluate the outcomes of treatments for neurosensory deficit after lower third molar surgery; 2) to investigate the effect of permanent neurosensory deficit from the patient’s perspective;3) to identify radiographic signs as predictors of inferior alveolar nerve (IAN) deficit in third molar surgery; 4)to monitor the long-term root movement and morbidities of the retained roots following coronectomy of the lower third molars.
(1) A systematic search on treatment modalities and their outcomes of neurosensory deficit after lower third molar surgery was performed. 4 surgical treatments and 2 non-surgical treatments were identified. Significant improvement in sensation was found in the majority of the subjects who received surgical or non-surgical treatment. Complete recovery was uncommon in all kinds of available treatments.
(2) Forty-eight subjects (24 cases) were recruited in a prospective case-control study comparing the general and oral health-related quality of life (QoL), life satisfaction and depression symptoms of patients with persistent lingual nerve (LN)or IAN neurosensory deficit (12 months or more) after third molar surgery with those who did not have such deficit. It was found that patients with persistent neurosensory deficit after third molar surgery have significantly poorer general and oral health-related QoL, worse life satisfaction and more depression symptoms than those without such deficits.
(3) Twelve patients with neurosensory deficit after lower third molar surgery (10 LN, 2 IAN) who received microsurgical repair of the affected nervewere recruited in a prospective longitudinal observational study of the treatmentoutcomes. Most patients with pain wererecovered after surgery. Subjective symptoms including numbness, taste sensation and speech were improved after LN repair. Improvement was noted in all three objective neurosensory tests at post-operative 12 months.

(4) 178lower third molars with one or more of the five radiographic signs suggesting of close proximity of their roots to the IAN were analyzed. It was found that radiographic signs of “darkening of root(s)” and “displacement of inferior alveolar canal by the root(s)” were associated with increased risk of intraoperative IAN exposure. In addition, “darkening of the root(s)” or co-existing radiographic signs were associated with an increased risk of post-operative IAN deficit.
(5) A phase 4 clinical trial with 612 lower third molar coronectomies was conducted to monitor the long term safety of the treatment. It was demonstrated that the technique has minimal morbidity in terms of infection, pain, dry socket or development of pathologies. Most retained roots (90.9%) migrated upward with the highest migration rate in the first 6 months, which gradually slowed down and stopped to migrate at 24months. 2.3% of the roots became exposed in the oral cavity and required removal. Re-operation to remove the exposed root did not cause any IAN deficit.published_or_final_version

Full textAbstract:
Background
Various analgesics are available for post-operative pain after third molar surgery. Combinations of different classes of analgesics may improve the overall efficacy of pain control as they covers different pain pathways. A great variation of combinations and dosages of analgesics have been suggested in the literature, yet it was still unclear what combination(s) and dosages were the most effective for acute post-operative dental pain. A systematic review of randomized clinical trials would help clinicians to make clinical judgment of which analgesic combination(s) would be the best for their patients for acute post-operative dental pain in terms of efficacy and safety.
Aim
To conduct a systematic review of randomized clinical trials to answer the clinical question “which analgesic combination and dosage is potentially the most effective and safe for acute post-operative dental pain control?”
Methods
A structured systematic literature search, with predefined inclusion and exclusion criteria, of the relevant computer databases and journals was performed. The search and the evaluations of articles were done by 2 independent reviewers in 3 rounds. Studies that fulfilled the pre-set criteria were included to enter the final review. The analgesic efficacy of the analgesic combinations reported in the included studies were presented by the objective pain measurements, sum of pain intensity at 6 hours (SPID6) and total pain relief at 6 hours (TOTPAR6). The SPID6 and TOTPAR6 of various combinations were adjusted after deducting from the effect of placebos of the respective studies. The adverse effects of the different analgesic combinations were also presented.
Results
There were 13 studies with 2843 subjects included in the final review. Eight groups of drug combinations with 13 different dosages were reported. The efficacies of the reported analgesic combinations have SPID6 scores ranged from 1.46 to 6.44 and TOTPAR6 scores ranged from 3.24 – 10.3. Among the analgesic combinations, ibuprofen 400mg + oxycodone HCL 5mg had the highest adjusted SPID6 (6.44), and a very higher adjusted TOTPAR6 (9.31), representing its efficacy could be superior to the other different analgesic combinations reported in this study. Nausea was the most common adverse effect of the analgesic combinations, with prevalence ranged from 0-55%. Most of the common adverse effects were related to the use of opioids in the combination. Three combinations of different dosages containing ibuprofen and caffeine were reported with the lowest prevalence of adverse effect.
Conclusions
This systematic review of randomized clinical trials has presented the efficacy and adverse effects of the various analgesic combinations for acute post-operative dental pain control. We have identified ibuprofen 400mg with oxycodone 5mg was more effective when compared to the other 12 combinations. Nausea was the most common adverse effects in an analgesic combination containing an opioid. Ibuprofen 200mg with caffeine 100mg or 200mg has a reasonable analgesic effect with fewer side effects when compared to the other analgesic combinations.published_or_final_version

The aim of this study primarily was to review pathological reports of all symptomatic third molar teeth removed in a private practice, and to use the data to support or refute routine removal of third molar teeth. All patients who underwent third molar tooth removal for symptoms,either systemic or local ,in a private practice over a twenty year period between 1987 and 2007 were included in the study. Specimens were sent for histological assessment by Oral Pathologists. The patient records were reviewed retrospectively. A total of 3427 third molar teeth were included in the study. There were 68.75% specimens which had some sort of pathology. Only 0.3% of specimens were reported as normal dental follicular tissue. There were 31.25% specimens of hyperplastic follicular tissue which was considered non pathologic as they consisted of normal dental follicular tissue with a mild chronic inflammatory cell infiltrate. However the 68.75% pathologic lesions consisted of 14.44% specimens with early dentigerous cysts, 8.11% with dentigerous cysts, 42.80% of paradental cysts and the remainder with other pathologies. The majority of the patients were in the second and third decades and mostly female. The age distribution of the patients suggested a progression from hyperplastic follicular tissue with a peak occurring at 17 years, to early dentigerous cysts at 19 years, to dentigerous cysts at 21 years. Paradental cyst formation, with a peak incidence at 19 years of age formed a large number of the pathological lesions found, and accounted for a large number of patients seeking treatment, owing to the symptoms associated. This study represents an analysis of the largest number of symptomatic third molar teeth submitted for histological assessment known. The data obtained was used to review the guidelines for the management of third molar teeth. From this study it can be concluded that symptomatic impacted third molar teeth should be removed early in the third decade in order to avoid general or local symptoms suffered by these patients.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgicoThird molar surgery is a frequent procedure in dentistry related to variable degrees of postoperative pain. In this context, non-steroidal anti-inflammatory drugs have been commonly used in studies that evaluated the efficacy of preemptive analgesia as a strategy for pain control. Thus, the aim of the present study was to evaluate the preemptive analgesic efficacy and anti-inflammatory effect of ibuprofen and etoricoxib in mandibular third molar surgery, compared with a placebo. A randomized, double-blind, placebo-controlled crossover trial was conducted with patients undergoing a surgical removal of mandibular third molars with similar pattern of bone inclusion and surgical difficult between right and left sides, requiring bone removal under local anesthesia. Eighteen eligible patients were allocated into three groups to receive 1 hour preoperatively a single dose of ibuprofen 400 mg, etoricoxib 120 mg, or placebo. Pain intensity, use of analgesic rescue medication, swelling and maximum mouth opening were evaluated. The overall median (minimum - maximum) of pain scores was different between groups (p < 0.0001): ibuprofen, 0.0 (0.0 â 5.5); etoricoxib, 0.0 (0.0 â 3.5); placebo, 1.0 (0.0 â 7.0). Etoricoxib reduced pain scores significantly in comparison with ibuprofen (p < 0.05). The pain score peak occurred 6 hours after surgery between 3 compared groups (p < 0.0001). Rescue medication was used in 83.33%, 75%, and 100% of surgical procedures receiving ibuprofen, etoricoxib, and placebo, respectively (p = 0.1967). The mean of consumed rescue medication was different between ibuprofen (1.7Â2.0), etoricoxib (0.8Â06), and placebo (1.0Â2.7) groups over the study period (p = 0.0052), and was significantly lower in etoricoxib group by comparison with the placebo group (p < 0.05). Among study periods, there was no statistically significant difference between groups in relation to median values of facial swelling (p > 0.05) and mean values of maximum mouth opening (p > 0.05). In conclusion, ibuprofen and etoricoxib significantly reduced the intensity of postoperative pain and the need for use of rescue medication compared to placebo group. Etoricoxib showed a better preemptive analgesic activity than ibuprofen. Both drugs did not exert significant anti-inflammatory effect able to reduce swelling and trismus in comparison with placebo group.

Nesse contexto, drogas anti-inflamatÃrias nÃo-estereoidais tÃm sido comumente utilizadas em estudos que avaliaram a eficÃcia da analgesia preemptiva como uma estratÃgia para controle da dor. Portanto, o objetivo do presente estudo foi avaliar a eficÃcia da analgesia preemptiva e aÃÃo anti-inflamatÃria do ibuprofeno e etoricoxibe em cirurgia de terceiros molares mandibulares comparado a um placebo. Foi realizado um ensaio clÃnico randomizado, duplo-cego, placebo-controlado cruzado com pacientes submetidos a cirurgia para remoÃÃo de terceiros molares mandibulares, com padrÃes similares de inclusÃo Ãssea e dificuldade cirÃrgica entre os lados direito e esquerdo, e que requeriam remoÃÃo Ãssea sob anestesia local. Dezoito pacientes elegÃveis foram randomicamente alocados em trÃs grupos para receber 1 hora preoperatoriamente dose Ãnica de ibuprofeno 400mg, etoricoxibe 120mg, ou placebo. Intensidade de dor, uso de medicaÃÃo analgÃsica de resgate, edema e mÃxima abertura bucal foram avaliados. A mediana (mÃnimo - mÃximo) global dos escores de dor diferiu entre os grupos (p < 0,0001): ibuprofeno, 0,0 (0,0 â 5,5); etoricoxibe, 0,0 (0,0 â 3,5); placebo, 1,0 (0,0 â 7,0). Etoricoxibe reduziu os escores de dor significantemente em comparaÃÃo ao ibuprofeno (p < 0,05). O pico de dor ocorreu 6 horas apÃs a cirurgia entre os 3 grupos comparados (p < 0,0001). MedicaÃÃo de resgate foi utilizada em 83,33%, 75% e 100% dos procedimentos cirÃrgicos que receberam ibuprofeno, etoricoxibe e placebo, respectivamente (p = 0,1967). A mÃdia de medicaÃÃo de resgate consumida diferiu entre os grupos ibuprofeno (1,7Â2,0) e etoricoxibe (0,8Â0,6) e placebo (1,0Â2,7) durante todo o perÃodo de estudo (p = 0,0052), e foi significantemente menor no grupo do etoricoxibe em comparaÃÃo com o grupo placebo (p < 0,05). Entre os perÃodos de avaliaÃÃo do estudo, nÃo existiu diferenÃa estatisticamente significante dos grupos entre si em relaÃÃo à mediana dos valores de edema facial (p > 0,05) e à mÃdia dos valores de mÃxima abertura bucal (p > 0,05). Em conclusÃo, ibuprofeno e etoricoxibe reduziram significantemente a intensidade de dor pÃs-operatÃria e a necessidade do uso de medicaÃÃo de resgate comparado ao grupo placebo. Etoricoxibe mostrou melhor atividade analgÃsica preemptiva do que o ibuprofeno. Ambas as drogas nÃo exerceram efeito anti-inflamatÃrio significante capaz de reduzir edema e trismo em comparaÃÃo ao grupo placebo.

sendo o monitoramento feito com uso de oxÃmetro de pulso, medidas regulares da pressÃo
arterial, frequÃncia cardÃaca e eletrocardiograma em cardioscÃpio, de acordo com as
recomendaÃÃes mÃnimas da AssociaÃÃo Americana de CirurgiÃes Orais e Maxilofaciais
(DâERAMO et al., 2003). No intervalo de 120 minutos, foram colhidas 10 amostras de 4ml,
apÃs injeÃÃo do anestÃsico local, e a anÃlise quantitativa das concentraÃÃes plasmÃticas de
mepivacaÃna foi realizada em HPLC. Os nÃveis plasmÃticos de mepivacaÃna em ambos os
grupos foram crescentes e significativos entre si em todos os respectivos intervalos de coletas
das amostras sanguÃneas. Os resultados foram obtidos e comparados os valores nos
respectivos momentos correspondentes entre os dois grupos, mostrando que as mÃdias da PA
sistÃlica e diastÃlica de todos os intervalos nÃo foram significantes quando comparados com
os valores obtidos na consulta prÃ-operatÃria. De acordo com os resultados deste estudo, foi
possÃvel concluir que a cirurgia de terceiros molares sob anestesia local, com mepivacaÃna 2%
e adrenalina 1:100000, quando respeitadas as margens de seguranÃas recomendadas pelo
fabricante, Ã um procedimento seguro e que nÃo existe diferenÃa clÃnica sistÃmica para o
paciente hÃgido quando no uso de doses de 108mg (5,4ml) e 216mg (10,8ml).Surgical removal of the third molars in clinical regime making use of local anesthetics plays a great role in the everyday practice of odontology. These drugs are safe when used in the proper way, but they can lead to undesirable outcomes when used in the wrong quantities or concentrations. Based on the knowledge of such principle and on surgical clinical practice, where levels of anesthetic concentration in the blood can reach near-toxic levels, a study measuring the systemic concentration of local anesthetic was made by collecting and analyzing, in equipment of High-performance liquid chromatography (HPLC), blood samples of patients who were submitted to local anesthesia with mepivacaine 2% and adrenaline 1:100000 for the removal of the third molars. The study was relevant because mepivacaine is frequently used in ambulatory surgeries of third molars, making it important to investigate the behavior of plasmatic levels and their possible toxic manifestations. The sample consisted of twenty-six patients of both sexes, subdivided in two groups according to the number of third molars removed: one group had two removed in a single session, the other group had four. Monitoring was done using pulse oxymetre, regular measuring of blood pressure, heart rate, and electrocardiogram in radioscopic, according to the minimum recommendations of the American Association of Oral and Maxillofacial Surgeons (DÂERAMO et al, 2003). In the interval of 120 minutes there were collected 10 samples of 4 mL after the injection of local anesthetic, and the quantitative analysis of the plasmatic concentrations of mepivacaine was done in HPLC. The plasmatic levels of mepivacaÃna in both groups were growing and significant amongst themselves in all the respective intervals of collections of the sanguine samples. After the results were obtained, the values at each corresponding moment for both groups were compared, showing that the averages of the systolic and diastolic pressure of all of the intervals were not significant when compared with the values obtained in the preoperative consultation. According to the results this study it was possible to conclude that the surgery of third molars under local anesthesia, with mepivacaine 2% and adrenaline 1:100000, when respecting the safety margins recommended by the manufacturer, is a safe procedure and that there are no clinical systemic differences to the healthy patient when doses between 108mg (5,4mL) and 216mg (10,8mL) are used.

Resumo: A cirurgia para extração de terceiros molares retidos, constitui a cirurgia de média complexidade mais frequentemente realizada em consultórios de cirurgiões-dentistas. Trata-se de estudo prospectivo, descritivo, com componente analítico, com o objetivo de avaliar a ansiedade dos pacientes no período que antecede o procedimento, as alterações hemodinâmicas, respiratórias e dor no intraoperatório em pacientes submetidos à extração de terceiros molares retidos sob anestesia local. Foram incluídos no estudo 42 sujeitos do sexo masculino, hígidos, com idade compreendida entre 18 e 34 anos. A anestesia foi feita com cloridrato de lidocaína a 2% com adrenalina 1:50.000 (Xylestesin®), na dose que variou de 72 a 144 mg, correspondente ao conteúdo de 2 a 4 tubetes (1,8 ml/tubete). Foram avaliados com auxílio de monitor multiparamétrico não-invasivo os seguintes parâmetros: pressão arterial sistólica, diastólica e média, frequência cardíaca, saturação periférica de O2 e frequência respiratória; o grau de ansiedade (escala de ansiedade para cirurgia odontológica - Escala de Corah) e dor (escala analógica- verbal). A análise estatística foi realizada por meio dos testes t de Student pareado e Wilcoxon pareado. O nível de significância foi fixado em 5% (p < 0,05). O tempo médio máximo de cirurgia foi 60 minutos, período considerado para análise dos resultados. Neste estudo, 20 pacientes apresentavam algum grau de ansiedade. Dor intensa foi referida por 7 pacientes nos momentos da osteotomia, odontossecção e luxação que necessitaram de complementação com anestésico local. A análise dos parâmetros hemodinâmicos e respiratórios mostrou em quase todos os momentos de avaliação, alterações significantes da pressão arterial média, diastólica e da frequência respiratória. Na maioria dos casos, 32 pacientes (76,2%) a saturação de O2 manteve-se normal (>95%), em todos os momentos. A análise dos dados mostra que pelo menos em algum momento do procedimento houve alteração clinicamente significante nos valores médios da pressão arterial sistólica e da frequência respiratória (alteração acima de 20% em relação ao valor inicial). Os resultados deste estudo permitem concluir que alterações hemodinâmicas e respiratórias podem ocorrer durante extrações de terceiros molares retidos, especialmente em pacientes ansiosos e com dor. A monitorização é importante na detecção e consequentemente prevenção dessas intercorrências, sendo particularmente útil em pacientes em que essas repercussões devam ser evitadas
Abstract: Surgical extraction of retained third molars is a surgery of medium complexity that is frequently performed in the office a dental surgeon. A prospective descriptive study with an analytical component was conducted, aimed at evaluating anxiety during the period preceding the procedure, as well as hemodynamic and respiratory alterations and pain during the intraoperative period in patients undergoing the extraction of retained third molars under local anesthesia. Forty-two healthy male subjects, ranging in age from 18 to 34 years were included in the study. Anesthesia was performed with lidocaine hydrochloride 2% with epinephrine 1:50,000 (Xylestesin®), at a dose ranging from 72 to 144mg, corresponding to 2 to 4 cartridges (1.8ml/ cartridge). A non-invasive multiparametric monitor was used to monitor the following parameters: systolic, diastolic and mean arterial blood pressure, heart rate, peripheral O2 saturation, respiratory rate; level of anxiety (anxiety scale for dental surgery - Corah's Scale) and pain (verbal analog scale). Statistical analysis was performed with a paired Student's t test and a paired Wilcoxon's test. The significance level was set at 5% (p < 0.05). The mean maximum duration of surgery was 60 minutes, which was the period considered for result analysis. In this study, twenty patients had some level of anxiety. Severe pain was reported in seven patients who required supplementation with local anesthesia during osteotomy, tooth sectioning and luxation. The analysis of hemodynamic and respiratory parameters showed in almost all the moments, significative alterations of systolic, diastolic and mean blood pressure. In the greater number of cases, 32 patients (76,2%), O2 saturation was normal (> 95%) all the time. The data analysis shows that at least at some point the procedure was clinically significant change in average systolic blood pressure and respiratory rate (change over 20% on the original).The results of this study enabled us to conclude that hemodynamic and respiratory alterations may occur during the extraction of retained third molars, especially in anxious patients with pain. Monitoring is important for the detection and thus prevention of these complications. Furthermore, it is particularly useful in patients in whom these repercussions must be avoided

Objetivo: avaliação da associação entre fatores de risco e complicações pós-operatórias em procedimentos de exodontia de terceiros molares mandibulares por técnica aberta.
Materiais e métodos: estudo longitudinal observacional prospetivo em pacientes com indicação de exodontia de terceiros molares mandibulares.
O paciente foi observado em dois tempos clínicos: preenchimento da ficha clínica de identificação e exodontia (T0) e avaliação pós-operatória oito dias depois (T1).
A cirurgia foi tutelada pelos docentes e as técnicas utilizadas foram selecionadas consoante a posição dentária e dificuldade de cada caso. A anestesia, sutura e medicação pós-operatórias foram protocoladas.
Na avaliação pós-operatória quantificou-se a dor utilizando uma escala visual analógica aos 3 e 8 dias pós-extração, e registou-se a ocorrência de hematoma, hemorragia, trismo, edema e alveolite.
Os dados recolhidos foram analisados com métodos de estatística descritiva e inferencial apropriados utilizando o software SPSS® v. 23.0.
Resultados: foram realizadas 30 exodontias em pacientes com média de idades de 21,23 ± 5,18 anos, 13 do género masculino e 17 do género feminino.
As complicações mais frequentes foram edema (76,7%) e trismo (63,3%), não se registou nenhum caso de alveolite.
Os fatores de risco com associação significativa à dor aos 8 dias foram: pacientes de maior idade (p=0,024), incisão trapezoidal (p=0,031) e tempo operatório mais longo (p=0,009). Os hábitos tabágicos foram o único fator significativamente associado à hemorragia (p=0,026). Quanto à ocorrência de trismo, o tempo operatório mais longo foi o único fator com relação estatisticamente significativa (p=0,012). O edema teve uma associação significativa com o recobrimento mucoso total (p=0,031) e com a posição mesioangular (p=0,001).
Conclusão: os resultados sugerem que a idade, os hábitos tabágicos, a posição e tipo de inclusão dentária, o tipo de incisão e o tempo operatório são fatores preditivos da incidência de complicações pós-operatórias na cirurgia de terceiros molares mandibulares.Objectives: assessment of the relation between risk factors and post-op complications for third molar complex extractions. Materials and methods: Prospective Coorte study including patients with indication for mandibular third molar extraction. The patient was observed in two moments: enrollment and surgery (T0) and postoperative evaluation (T1), after one week. The surgery was supervised by oral surgery professors and the techniques used were selected according to the dental position and the difficulty of each case. Local anesthesia, suture and postoperative medication were the same for all cases. Postoperative pain was evaluated using a visual analogue scale at 3 and 8 days after extraction, and the occurrence of hematoma, bleeding, trismus, swelling and alveolitis was registered. The data collected was analyzed using appropriate descriptive and inferential statistics methods, using SPSS® software (v. 23.0). Results: A total of 30 third molars were extracted. The mean patient age was 21.23 ± 5.18 years, 13 males and 17 females. The most common complications were swelling (76.7%) and trismus (63.3%). There were no cases of dry socket. The risk factors with significant association with pain at the eighth day were older patients (p=0.024), trapezoidal flap (p=0.031) and long operative time (p=0.009). Smoking was the only factor associated with bleeding (p=0.026). The swelling had a significant association with total soft tissue impaction (p=0.031) and with the mesioangular position (p=0.001). Conclusion: The results suggest that age, cigarette smoking, teeth position and impaction level, type of incision and operative time are the predictive factors for the incidence of postoperative complications in mandibular third molar extraction.

AbstractThird molar impactions is one of the commonest minor oral surgical procedures in the realm of the oral and maxillofacial surgeon. Many basic principles of minor oral surgery have to be applied in a logical manner to attain a good healing. The assessment, clinical and radiographic evaluation plays an important role in selecting the right technique to ensure good results. This chapter aims to go through the basics of third molar impactions in a sequential way to guide the clinician to take the right decisions.

AbstractThe trigeminal nerve constitutes the largest sensory cortex representation in the brain compared to any other sensory nerve. This is likely due to the fact that the trigeminal nerve underpins our very existence, as it protects, sensorially, our senses including the organs that provide sight, smell, taste, hearing, speech and meninges protecting our brain.Neurophysiologically, our affective and limbic systems in our brains are alerted before we even set foot in the dental surgery and the patient’s brain is anticipating and aligned for pain experience. Thus, when trigeminal nerve injuries occur, which in the main are preventable, the majority of patients experience mixed symptoms including ongoing and elicited neuropathic pain, numbness and altered sensation. These neuropathic features cause significant impact on the patients’ ability to function, for example, cold allodynia prevents the patient enjoying cold foods and drinks and undertaking outdoor activities or elicited pain on touch frequently interferes with sleep. The resultant chronic symptoms and functional impedance often result in significant psychological morbidity.There is no magic bullet to resolve these sensory nerve injuries, and our specialty is beholden to prevent nerve injuries where possible. The patient must have the appropriate consent, and their expectation is managed with understanding the potential benefits and risks for their chosen interventions.Prevention and management of nerve injuries related to local anaesthesia, implants and third molar surgery are outlined in this chapter. There is insufficient capacity to go in-depth for each area, but the author has provided up to date evidence base where it exists and some strategies to minimize and manage optimally these unfortunate complications.

Full textAbstract:
Bleb-related endophthalmitis is one of the most visually devastating complications of glaucoma filtering surgery. Endophthalmitis associated with a functioning filtering bleb may develop months or years postoperatively. Early postoperative endophthalmitis occurs within 6 weeks following the surgery, and late endophthalmitis occurs after this 6-week window. Early detection and rapid institution of appropriate treatment is important in optimizing outcomes and preserving vision. Blebitis is defined as an infection localized to the bleb and surrounding tissues, including the anterior chamber. Blebitis lacks vitreous involvement. Ocular signs of blebitis may include hyperemia around the bleb site, focal infiltrate in the bleb, bleb purulence, and anterior chamber reaction. Bleb-related endophthalmitis encompasses the findings of blebitis with concurrent vitreous inflammation. The presence of vitreous inflammation differentiates bleb-related endophthalmitis from blebitis (Figure 24.1). Risk factors for bleb-related infections are listed in Table 24.1. Bleb morphology and the presence of a bleb leak affect the risk of blebitis or endophthalmitis. Bleb leaks have been identified as the single most important risk factor for the development of bleb-related infections. In a case-control study by Soltau et al, Seidel-positive bleb leaks increased the risk of bleb infection nearly 26-fold. A multicenter study also found that a bleb leak is a major risk factor for blebitis and endopthalmitis. In a review of 20 endophthalmitis cases, 55% of the patients (11 patients) had a Seidel-positive leak following filtering surgery, and three-quarters (15 patients) were noted to have a thin or avascular bleb. Recurrent bleb leaks were observed in over a third of the patients. Song et al found that bleb leaks occurred in 27% of eyes (13 of 49 eyes) with delayed-onset bleb-related endophthalmitis. It is recommended that the clinician routinely monitor patients for bleb leaks and make appropriate interventions to resolve the leak once it is identified. The advent of antifibrotic agents has improved the success rate of traditional filtering surgery but has also increased the incidence of bleb-related infections. Greenfield et al demonstrated that mitomycin-C (MMC) increases the risk of bleb leak.

Central third bone-patellar tendon-bone (BPTB) autografts are commonly used for anterior cruciate ligament (ACL) reconstructions. Following surgery, complications arise at the donor site, including extension deficits and anterior knee pain [1]. These complications are partially caused by inadequate healing of the patellar tendon (PT) as well as adhesions in the anterior interval. Recent clinical data have suggested these are contributing factors in the early development of osteoarthrosis following ACL reconstruction [2]. Thus, it is necessary to understand the changes in mechanical and viscoelastic behavior in the healing PT.

The Fontan procedure is a surgery performed to treat patients with single ventricle congenital heart defects. The Fontan is the final of three surgical stages. The first stage consists of aortic reconstruction, in a Norwood procedure or variant thereof. In the second stage, the Bidirectional Glenn procedure, the superior vena cava (SVC) is disconnected from the heart and redirected into the pulmonary arteries (PAs). In the third and final stage, the inferior vena cava (IVC) is connected to PAs via a straight Gore-Tex tube, forming a T-shaped junction. Although early survival rates following the Fontan procedure can exceed 90%, significant morbidity remains after surgery including venous hemodynamic abnormalities, diminished exercise capacity, thromboembolic complications, protein-losing enteropathy, heart transplant etc. [1].

Three consecutive randomized open studies have been carried out in 892 patients undergoing abdominal, gynecological, thoracic or urological surgery. They were over 40 years old and presented at least one of the following risk factors for thrombosis: previous thromboembolism, obesity, varicose veins, malignancy (30% in these studies), pre-operative hospitalization over 5 days, estrogen therapy, chronic cardiac disease or bronchitis. The two groups of each trial were well matched with regard to population characteristics. The third trial included higher rate of patients undergoing urologic surgery. Isotopic venous thromboses and bleeding complications were assessed after subcutaneous administration of a low molecular weight (LMW) heparin fragment (Enoxaparin, 1 mg = 100 Anti-Xa I.U.) or unfractionated heparin (UH). The 3 studies compared 3 × 5,000 IU UH daily with 1 × 60 mg, 1 × 40 mg, or 1 × 20 mg LMW heparin daily. Thromboembolic event rates were not significantly different among the groups (UH : 3.6, 2.8, 7.6% respectively compared to LMWH : 3, 2.8, 3.7%). Significant decrease of hematocrit and hemoglobin were only observed in patients receiving 60 mg Enoxaparin (as compared to UH) whilst in the 2 other trials no difference could be evidenced between the 2 populations. The metaanalysis of the three studies on the “intention to treat” patients gave results consistent with those observed in good compliers. The three consecutive studies showed homogeneous results (p = 0.20), the Mantel Haenszel test did not evidence a global difference between Enoxaparin and unfractionated Heparin (p = 0.54). These results suggest that an optimal dosage of 20 mg per day of Enoxaparin is safe and as efficient as UH 5,000 IU × 3 in the prevention of post-operative thrombosis in this population.

70 patients were randomized to 3 groups. Group I : patients received 5,000 IU calciparineR subcutaneously given 2h before operation, twice a day for 3 days and then, doses were adjusted ty heparin levels. Groups II and III : 2,500 IU Kabi 2165 were given instead of calciparineR, but in group III, a single daily dose of 5,000 IU Kabi 2165 was administered from the third day. Fibrino-peptide A (FPA), FPA generation, D-dimers were measured in plasma by ELISA methods. Anti Xa activity, Xa generation, heparin cofactor II (HC II), antithrombin III (AT III) were assayed in plasma using amidolytic methods. Serial measurements were done : pre-operatively, 2 and 8h after the first heparin injection and on the 7th post-operative day, before heparin administration. Pre-operatively, the mean level of D-dimers was higher (p<0.05) in 9 patients with bleeding complications after surgery (0.83 ± 0.57 pg/ml) compared to other patients (0.42 ± 0.33 pg/ml) 2h after heparin injection : 1) Xa activity was lower (p<0.001) in group I (<0.05 IU/ml) than in groups II and III (0.137 ± 0.1 IU/ml) ; 2) inhibition of Xa generation decreased (p<0.001) in group I (11.7 ± 8%) compared to that in groups II and III (25.8 ± 13%) ; 3) inhibition of FPA generation was lower (p<0.05) in group I (27.1 ± 32.2%) than in groups II and III (45.7 ± 29.2%) ; 4) diminution of D-dimers under heparin (0.37 ± 0.28 pg/ml) was only significant (p<0.05) in groups II and III. 8h after the first heparin injection, in all groups : 1) D-dimers increased (p<0.001) compared to pre-operative values ; 2) AT III and HC II diminished (p<0.001) ; 3) no anti Xa activity and no inhibition of Xa and FPA generation were found. On the 7th day : 1) 4 patiertts with deep vein thrombosis had higher FPA than other patients ; 2) AT III but not HC II fell in group I (p<0.05) ; 3) no anti Xa activity and no inhibition of Xa and FPA generation were observed in all groups. In conclusion : 1) although clinical results are similar in the 3 groups, Xa activity, Xa generation, FPA generation change differently according to the heparin used ; 2) the occurence of deep vein thrombosis is followed by an FPA increase and bleeding complications are correlated with a high level of pre-operative D-dimers.
