Full textNowadays, it is known that the determination of the pulp vitality testing only its nerve sensorial response through thermal or electrical tests is discussable because those procedures are not sufficiently sensitive to determine the degree of pulp involvement. Besides the vitality of the pulp does not only depend on its nerve condition, but on its blood supply too. Another factor to consider during the pulp diagnostic, independently of the nature of stimulus or their intensity, is the possibility to occur non reliable responses in excessively anxious patients face to the dentistry treatment. The diagnosis of the pulp vitality by the measurement of the dental crown temperature such as the infrared thermography (which evaluates the temperature distribution in a body through the radiation emitted by its surface) arises as a possibility to overcome the sensitivity tests disadvantages, for example: the stimulation necessity, the variants due to the thickness of the dentin and enamel, the age, the condition of the dental structure and etc. This study evaluated the applicability of the infrared thermography test in the analysis of temperatures decline produced by thermal test using cold spray, and its viability as an aid for the endodontic diagnostic. Using thermal imaging, this methodology analyzed the temperature of the crowns surface of four teeth with vitality and two endodontically treated teeth when submitted to the cold test with and without the use of rubber dam. The results did not show a significant difference between teeth conditions with regard to the crowns surface temperature and the use of rubber dam did not affect these results. The proposed methodology used in this study showed to be highly efficient to analyzing the thermal changes on the dental surface; however new studies must be performed to turn infrared thermography a practicable aid into the endodontic practice.

This research that aimed to evaluate endodontic treatments performed by undergraduate dental UFPB and factors for failure by clinical examination, radiographic and symptomatic cases in CBCT. Were selected 120 patients through analysis of 557 medical records are on file in the Department of Endodontics that were seen between the years 2007 to 2011. The patients' ages ranged from 15 to 78 years, 31 were male and 89 were female. The diagnosis chronic apical periodontitis was 50% of cases, followed by chronic periapical abscess (15.0%). With respect to dental group the most frequent were upper central incisors (28.3%) and pre-molars (24.2%). As for the number of sessions required to treat 59.2% of the cases was conducted in three sessions. The time of follow up ranged from 1 ½ years to 4 ½ years. Regarding the clinical management 73.3% the patients had no signs or symptoms, but the rest of the sample signs and symptoms were: 11.7% pain only by percussion and 3.3% pain by percussion with mobility. The presence of blackened crown was recorded in 37.5% of cases. The majority of patients had appropriate endodontic treatment (72.5%), keeper intracanal absent (88.3%) and adequate coronal restoration (74.2%). Most radiographic images in the index PAI showed normal appearance bringing a success index (PAI 1 + PAI 2) 70%. In index Strindberg most (62.5%) of the treatments were considered successful, with 30.0% uncertain healing and 7.5% failure. The percentage with endodontic treatment and adequate coronal restoration and success in Strindberg and PAI index was highest among those who had no signs and symptoms, with a significant association. The percentage of cases with endodontic treatment and adequate coronal restoration was higher among cases successfully than among uncured, with significant association. The success rate by Strindberg and PAIwas higher among cases with vital pulp than pulp necrosis. A significant association between the index PAI and the index CTCTPAI, but the measures tomography and radiography, the mean and median were higher in CT than on radiographs, significant difference betweenthe two methods.Concludes that the clinical and radiographic examinations are important in the process of preservation endodontic, but the CBCT is more suitable for this type of diagnosis, due to higher sensitivity and specificity in evidence of endodontic failure.

Com relação ao grupo dental os mais freqüentes foram: Incisivos centrais superiores (28,3%) e Prémolares superiores (24,2%). Quanto ao número de sessões requeridas para o tratamento 59,2% dos casos foi realizada em três sessões. O tempo de proservação variou entre 1 ano e meio a 4 anos e meio. Em relação ao controle clínico 73,3% dos pacientes não apresentaram sinais e sintomas, porém no restante da amostra os sinais e sintomas mais freqüentes foram: 11,7% dor somente por percussão e 3,3% dor por percussão e mobilidade. A presença de coroa escurecida foi registrada em 37,5% dos casos. A maioria dos pacientes apresentava tratamento endodôntico adequado (72,5%), retentor intracanal ausente (88,3%) e restauração coronária adequada (74,2%). A maioria das imagens radiográficas no índice PAI apresentava aspecto normal trazendo um índice de sucesso (PAI 1+PAI 2) de 70%. No índice de Strindberg a maioria (62,5%) dos tratamentos foi considerada sucesso, 30,0% com cura incerta e 7,5% de insucesso. O percentual com tratamento endodôntico e restauração coronária adequada e sucesso no índice Strindberg e PAI foi mais elevado entre os que não apresentavam sinais e sintomas, havendo associação significativa. O percentual de casos com tratamento endodôntico e restauração coronária adequada foi maior entre os casos com sucesso do que entre os não curados, havendo associação significativa. O percentual de sucesso pelo Strindberg e PAI foi mais elevado entre os casos com polpa vital do que com necrose pulpar. Houve associação significativa entre o índice CBCTPAI e o índice PAI, porém nas medidas da tomografia e radiografia, a média e a mediana foram mais elevadas na tomografia do que na radiografia, havendo diferença significativa entre os dois métodos.

Full textIn the traditional education model, developing of cognitive learning, psychomotor and conduct aspects during the endodontic diagnosis and treatment planning become a problem for students due to the relatively limited number of clinical experiences in diagnosis as well as the availability of adequate teacher/student ratio and the insufficient number of patients. Thus, the development of new strategies for effective teaching and learning process and evaluations in diagnosis would be interesting for education in Endodontics. The aim of this study was verified and compares the students performance in Endodontic varying the educational methodology where the use of hypermedia technology and internet could make the teaching-learning process easier. For this, undergraduate dental students from three universities were divided in three groups according to the applied teaching-learning methodology: GI - Traditional centered teacher - control group (n=23), GII Adding a review before the traditional centered teacher method (n = 30) and GIII - Self-instruction using hypermedia technology accessed by Internet (n = 90). The www.endo-e.com website was used as a self-instruction and evaluation method that includes diagnosis of pulp and periapical diseases, root canal therapy and clinical cases simulation. The results were statistically analyzed using Kruskal-Wallis followed by Student-Newman-Keuls tests. The strategy focused on the teacher that used previous review, where students interacted with simulated conditions following traditional class was the most efficient method and showed statistically significant difference (p<0,01) when compared with other strategies. There were no statistically significant differences between groups using strategies focused just on the teacher and student without the use of interactivity. Hypermedia technology and the use of Internet showed equivalence with the conventional teaching and learning strategy (teacher-centered) and can be considered as a complementary strategy to facilitate the diagnosis learning in Endodontics.

Full textThe difficulties imposed by the anatomy of the root canal system are a frequent cause of endodontic treatment failures, especially in upper first molars where the prevalence of the second mesiobuccal canal (MB2) is variable. Several methods have been proposed to detect this root canal, but also is important to consider the influence of the clinical condition of the over tooth its the correct diagnosis. Therefore, this study was aimed: i) to assess the diagnostic ability of conventional radiography and CBCT with different voxel sizes in the detection of MB2 in different root conditions; and, ii) to assess the reproducibility of this diagnosis under the same conditions. Radiographs and CBCT scans (0.2-mm, 0.25-mm and 0.3-mm voxel) of eighty-nine extracted human molars were performed in three steps: first mesiobuccal canal (MB1) non filled, filled and after deobturation. Then, samples were cleared. Three examiners, calibrated and blinded, evaluated the images and pointed out the presence or absence of MB2. Statistical analysis was crried on with the PASW Statistics 17.0 software. It was observed that CBCT is a secure complementary method for investigating the presence of MB2. Moreover, when the MB1 canal is filled should be choose the 0.2-mm protocol. The 0.3-mm voxel size images proved to be adequate for a correct diagnosis when the MB1 was non filled or deobturated. In the assessment of diagnostic reproducibility, it can was concluded that the MB1 seemed to be a determinant factor for the result outcome canal condition when compared to the voxel size and the examiner’s experience. These results should be considered when an endodontic re-treatment was indicated, specially when the presence of a MB2 is suspected. The removal of endodontic material prior to request the images exams reduces the presence of artifacts, allowing the use of the 0.3-mm voxel protocol. It was able to allow a correct diagnosis with less patient exposure to the X ray.

Este estudo objetivou analisar comparativamente a tomografia volumétrica Cone-Beam e o exame radiográfico periapical, pela técnica de Clark, quanto à identificação de acidentes e complicações endodônticas, simuladas, de interesse endodôntico. Dezesseis dentes humanos, em três mandíbulas humanas, foram submetidos ao preparo de 20 alterações/lesões, de modo a simular situações que podem constituir-se em complicações para o diagnóstico e tratamento endodôntico. As simulações foram divididas em quatro grupos: G1) fragmento de lima fraturada no conduto radicular; G2) perfurações/rasgos no conduto radicular; G3) núcleos metálicos com desvio em relação ao trajeto do canal radicular e; G4) reabsorções externas. Cada dente foi submetido a exame radiográfico periapical pela técnica de Clark e cada mandíbula, a exame por Tomografia Computadorizada Cone-Beam. A análise dos exames foi realizada por um único observador, especialista em radiologia odontológica. Os resultados gerais utilizando-se o teste estatístico de McNemar demonstraram diferença estatisticamente significante (p < 0,05) para a Tomografia Computadorizada Cone-Beam em relação às radiografias periapicais. A análise estatística dos resultados individuais por alteração/lesão, utilizando-se o teste estatístico de Wilcoxon, demonstrou que houve superioridade da Tomografia Computadorizada Cone-Beam na identificação de reabsorções, com valor estatisticamente significante (p < 0,05). De acordo com os resultados pode-se concluir que, de uma forma geral, a Tomografia Computadorizada Cone-Beam apresentou superioridade em relação às radiografias periapicais convencionais, na identificação das alterações/lesões simuladas.
This study aimed to analyze and compare volumetric tomography ConeBeam and periapical examination, by technique of Clark, identifying accidents and endodontic complications, which were simulated, for endodontic interest. Sixteen human teeth from three human jaws were submitted to preparation of 20 changes/injuries in order to simulate situations that can lead to complications for diagnosis and endodontic treatment. The simulations were divided into four groups: G1) fragment of fractured file in radicular duct; G2) holes/slots in radicular duct; G3) metal cores with deviation from the path of root canal and, G4) external resorption. Each tooth was submitted to examination of periapical radiography, by technique of Clark and each jaw, by the examination of Cone-Beam Computed Tomography. The analysis of the tests was performed by a single observer, a specialist in dental radiology. The overall results using McNemar statistical test showed a difference statistically significant (p < 0.05) for Cone-Beam Computed Tomography if compared to periapical radiographs. Statistical analysis of individual results for alteration/defect, using Wilcoxon statistical test showed superiority of Cone-Beam Computed Tomography to identify resorptions, with statistically significant value (p < 0.05). According to the results it can be concluded that, generally, the Cone-Beam Computed Tomography showed superiority in relation to conventional periapical radiographs, identifying simulated changes/injuries.

Full textThe aim of this study was to compare the effectiveness of Cone Beam Computed Tomography and periapical radiography as a follow-up method of periapical lesions after endodontic treatment. We evaluated in the study radiographs and tomography scans of 1,462 individuals with cleft lip and palate at the Hospital of Rehabilitation of Craniofacial Anomalies - University of Sao Paulo who came for treatment endodontic between the years 2009 and 2011. According to inclusion criteria were selected 46 single-rooted teeth with periapical lesions, which were divided into groups radiographic evaluation (Group I) and tomographic evaluation (Group II). Data were analyzed using the PAI score for periapical changes found. The results were observed that statistically significant differences in the groups studied. In 34 cases the CT scores attributed to the teeth evaluated were higher than the scores attributed to the radiographs of same teeth evaluated, demonstrating the greater precision of Cone Beam Computed Tomography. Thus, analysis of results obtained in this work demonstrates that the Cone Beam Computed Tomography is more effective in follow-up of periapical lesions than periapical radiography after endodontic treatment in patients with cleft lip and palate.

Resumo: O presente trabalho teve como objetivos: avaliar a acurácia da Tomografia Computadorizada de Feixe Cônico e de radiografias periapicais digitais no diagnóstico de reabsorções radiculares em dentes traumatizados e verificar a influência da presença do material obturador na detecção dessas lesões (capítulo 1); relatar dois casos clínicos de reabsorções radiculares cujo diagnóstico foi realizado por meio da Tomografia Computadorizada de Feixe Cônico (capítulo 2). No capítulo 1, a amostra desta pesquisa foi constituída por radiografias e tomografias de pacientes com reabsorções radiculares e histórico de trauma dental, coletadas do banco de dados de uma clínica radiológica. Vinte oito dentes com reabsorções inflamatórias externas (14 com tratamento endodôntico e 14 sem tratamento endodôntico), 8 dentes com reabsorções inflamatórias internas e 4 dentes com reabsorção por substituição foram incluídos. Vinte casos sem reabsorção foram selecionados para o grupo controle. A análise das imagens foi realizada por 2 endodontistas e 2 radiologistas, previamente calibrados. Os resultados revelaram que a sensibilidade, especificidade e acurácia da Tomografia Computadorizada de Feixe Cônico foi superior às radiografias periapicais para o diagnóstico de reabsorções inflamatórias externas e internas (p<0.05 / Teste t). Para reabsorção por substituição, não houve diferença entre os métodos avaliados (p>0.05 / Teste t). Nos dentes tratados endodonticamente, a tomografia também apresentou resultados estatisticamente superiores para o diagnóstico das reabsorções inflamatórias externas (p=0.0138 / Teste t). No capítulo 2, dois casos clínicos de reabsorções radiculares (1 de reabsorção cervical externa e 1 de reabsorção inflamatória interna) foram descritos. A abordagem terapêutica adotada durante o diagnóstico e tratamento foi minuciosamente detalhada. O tratamento da reabsorção cervical externa foi multidisciplinar e envolveu a endodontia e periodontia. No caso com reabsorção interna, apenas o tratamento endodôntico foi necessário. Após o período de proservação, ambos os casos apresentaram-se sem sintomatologia e o sucesso clínico foi verificado. Concluiu-se que a Tomografia Computadorizada de Feixe Cônico foi superior às radiografias periapicais em relação ao diagnóstico de reabsorções inflamatórias (capítulo 1) e apresenta-se como um importante recurso de diagnóstico auxiliar para a detecção, localização e planejamento do tratamento clínico das reabsorções radiculares (capítulo 2)
Abstract: The aims of this study were: to evaluate the accuracy of cone beam computed tomography (CBCT) and digital periapical radiography in diagnosing root resorption following dental trauma and to verify the influence of filling material in detecting these lesions. (Chapter 1); describe two cases reports of root resorptions diagnosed by CBCT (Chapter 2). In chapter 1, periapical radiographs and CBCT images of patients with root resorption and a history of dental trauma from the database of a private radiology clinic were retrospectively reviewed. The sample comprised 28 teeth with external inflammatory resorption (14 with and 14 without endodontic treatment), 8 teeth with internal inflammatory resorption, 4 teeth with replacement resorption and 20 normal teeth as the control group. Images were analyzed by two radiologists and two endodontists who were previously calibrated. The results showed that the sensitivity, specificity and accuracy of CBCT in diagnosing internal and external inflammatory resorption was significantly higher than for radiography (p < 0.05 / t test). For replacement resorption, no statistical difference was noted (p > 0.05 / t test). In endodontically treated teeth, CBCT was also statistically superior in diagnosing external inflammatory resorption (p = 0.0138 / t test). In chapter 2, two cases reports of root resorptions (cervical external resorption and internal inflammatory resorption) were described. The therapeutic approach adopted for the diagnosis and treatment was detailed. Treatment of cervical external resorption involved endodontics and periodontics.In casewith inflammatory internal resorption, only endodontic treatment wasnecessary. After the observation period, both cases were presented without symptoms and clinical success was confirmed. Based on these findings, it was concluded that CBCT was superior to periapical radiography in diagnosing inflammatory root resorption following dental trauma, with or without endodontic treatment (Chapter 1) and presents itself as an important resource of as an auxiliary diagnosis for the detection, location and planning of the clinical treatment of root resorption (Chapter 2)

Full textA área da imagiologia e da endodontia estão em completa interligação. O diagnóstico e a concretização de um plano de tratamento dependem dos achados clínicos assim como os imagiológicos. No entanto, a quantidade de técnicas imagiológicas que hoje estão à disposição do clínico e do paciente invocam a necessidade de compreender quais as vantagens na utilização dos diversos meios para o sucesso no tratamento. Foi então realizada uma pesquisa nas bases de dados online PubMed, Scielo, Science Direct e b-On, compreendida entre o ano de 1996 e 2015, tendo sido seleccionados 48 artigos e o recurso a 3 livros para a concretização do trabalho. As conclusões obtidas são de que apesar da evolução e da descoberta de novas técnicas imagiológicas, não existe nenhuma que seja nem aconselhada ou desaconselhada ou sensível a 100% para o diagnóstico das patologias e que o recurso às diversas técnicas deve ter por base certos critérios que justifiquem a sua utilização. The imaging and endodontics area are in full interconnection. The diagnoses and the implementation of a treatment plan depend on the clinical as well as imaging foundings. However, the amount of imaging techniques that is now available to the clinician and patient, cal the need to understand the advantages in the use of various means to success in treatment. It was then carried out a search in online databases PubMed, Scielo, Science Direct and b -On, between 1996 and 2015 and was selected 48 articles and the use of 3 books for completing the work. The conclusions reached are in spite of evolution and discovery of new imaging techniques, there is none that is either recommended or discouraged or sensible at 100% for the diagnosis and that the use of various techniques should be based on certain criteria that justify its use.

Full textVarious imaging modalities have been used in the dentomaxillofacial fields over the past few decades, none of them with entirely satisfactory results. Two anatomical structures were explored in this study. On the one hand, the temporomandibular joint (TMJ); in addition endodontic structures. The first chapter of this document, based on a bibliographical synthesis, allowed, to expose various methods of the dentomaxillotacial imaging. We briefly pointed out the principles 0f image acquisition and three-dimensional image processing. The following chapter exposed methodology of exploration and analysis of the TMJ images. After a review of anatomical and pathological aspects of this joint, we reviewed briefly the imaging modalities and then exposed two protocols (3D imaging and analysis) which we carried out. First was an evaluation of the 2D TMJ images, and the second a methodology of 3D imaging and analysis of this joint. The last chapter was devoted to the exploration and the analysis of the endodontic images. In the same way, various in vivo and in vitro methods were reviewed. Then, we exposed the 3D imaging of the endodontic structures

Full textThe majority of patients who suffer from toothache report referred pain to other sites in the head and neck. Thus, the aim of this study was to investigate the clinical and psychophysical characteristics of referred pain in the orofacial region and how factors such as intensity, duration and nature of odontogenic pain might modulate them. We employed psychophysical and clinical methods to correlate pain perception with the anatomy and physiology of the trigeminal system. Sixty patients reporting primary toothache were investigated as to the clinical and psychophysical aspects of their pains symptoms and signals (intensity, duration, location and state of the pulp inflammatory process). Pain intensity and state of irreversible pulp inflammation were found to significantly affect facilitate the incidence of referred pain and its spread across vertical laminations. Considering these results, we proposed a physiological model based on both neuronal integration (spatial and temporal summation) and the topographic organization of the trigeminal system, which is able to explain the observed characteristics of referred dental pain.

Este trabalho tem como pano de fundo, as seguintes etapas: planeamento da cirurgia, indicações, contra-indicações, comparação entre a cirurgia tradicional e a cirurgia atual, instrumentos e equipamentos usados. Por outro lado, estabelece-se uma comparação entre materiais, como MTA versus tecnologia bio-cerâmica. O anteriormente elencado tem como objetivo final a preservação do elemento dentário, que necessita de ser reabilitado. This work presents a literature review on the Periapical surgery, having as a backdrop, the following steps: planning of surgery, indications, contraindications, comparison between traditional surgery and the current, instruments and equipment used in surgery. On the other hand, provides a comparison between materials, such as bio-ceramic versus MTA technology. This procedure has as final goal the preservention of the tooth under treatment.

Full textThe oral cavity presents a wide range of human and microbial proteins. This study aims to identify and annotate the human and microbial proteins in the literature associated with endodontic infection. The study developed identified 523 proteins being 385 microbial and 138 human, of which 96 are unique proteins of endodontic pathology. The information on these proteins has been noted in the database OralOme which can be accessed via the web by OralCard interface. Functional characterization of the endodontic OralOma disease possible to infer an increased number of molecular processes involved in protein activity and receptor transport activity. The determination of protein-protein interactions between human proteins and microbial proteins identified that a large number of interactions are associated with defense functions and attempt invasion of host tissues. Many proteins identified in the endodontic disease don’t present quantification data and merely identifying potential biomarkers for endodontic disease. This suggest new studies of proteomics to enable this quantification.

Full textIntroduction: There is currently a growing global concern about the overuse of antibiotics and the consequent emergence of bacterial strains resistant to these drugs. Objectives: The main purpose of this investigation was to determine antibiotic prescribing habits in the treatment of endodontic disease, including whether dentists appropriately select the use of antibiotics according to the endodontic diagnosis established by them. Materials and Methods: A questionnaire was prepared in which 219 responses were obtained. The data analysis was performed through descriptive and inferential statistics and the Mann-Whitney test and the Chi-Square test. Results: 219 dentists practicing their clinical practice in the various areas of dentistry and in Portuguese territory answered the questionnaire of this investigation. Among the several questions that addressed different diagnoses, we found that the diagnosis in which they reported the highest number of prescription was in the case of facial cellulitis or non-draining abscess (89%) n = 195, being in agreement with the current guidelines. However, we have also noticed that there is a high occurrence of prescription in other diagnoses. The antibiotics most commonly used by clinicians are amoxicillin plus clavulanic acid and azithromycin for patients allergic to penicillin. Conclusion: Antibiotics are prescribed for the treatment of pulp-periradicular diagnoses where there is no clinical indication, by scientific evidence, for this. The results of this study suggest that there are gaps in the knowledge about the correct indication for the prescription of antibiotics in endodontic practice.

Full textOne of the great challenges presented to the dentist in the daily clinic is to make a correct diagnosis of different clinical conditions, including vertical root fracture. These can vary in extent and are most often associated with endodontic treated teeth. The diagnosis of a vertical root fracture in dental medicine is crucial when avoiding to lose surrounding bone structure for implant rehabilitation. For this work a bibliographical narrative revision was made, using data bases such as Pubmed, Medline, Scielo and Google Scholar. The main objective of this dissertation is to show the relevance of the different resources that the dental practitioner counts for the diagnosis of root vertical fracture and to determine which one is most appropriate for current use.

Full textEndodontic infections involve the invasion and multiplication of microorganisms in dental pulp and periapical tissues. They include, therefore, two types of pathologies: pulp pathologies and periapical pathologies. Pulp pathologies include the reversible pulpitis, irreversible pulpitis and pulp necrosis. Periapical pathologies include acute apical abscess, chronic apical abscess, acute apical periodontitis, chronic apical periodontitis, periapical granuloma and periapical cyst. Pulpal and periapical disease exhibit different clinical manifestations that along with signs and symptoms manifested, permit to make the diagnosis of the type of endodontic infection. Endodontic infections are associated with a high diversity of bacteria, often being entitled endodontic polymicrobial infections. It is known that microorganisms are the main cause of pulp and periapical diseases and, therefore, the main objective of endodontic treatment consist in elimination of microorganisms and prevention of re-infection. Endodontic infections treatment is based on the chemical-mechanical preparation of the root canal system - instrumentation and irrigation – further obturation and it is culminate with the final restoration or rehabilitation treatment. This work aims to acquire a broader knowledge about types of endodontic infections, the several diagnostics and mainly to the various treatment options available in Endodontics. For such it was realized a literature-based on scientific articles published in the databases PubMed, Scielo and Science Direct as well as some books related to the topic.
