Background: Odontogenic cysts are the most common form of cystic lesions affecting the maxillofacial region and one of the main causes of the damage of these bones.Objective: To determine the frequency of different types of odontogenic jaw cysts diagnose among the Bangladeshi population.Study design: A descriptive observational study was made of 62 patients.Study setting and period: The study was done in the Department of Oral & Maxillofacial Surgery, Bangabandhu Sheikh Mujib Medical University, Shahbag, Dhaka-1000 from 1st March 2010 to 28th February2011.Participants: Sixty-two patients with cystic lesions in the maxillofacial region were selected for the study.Methods: Patients who attended in the Oral & Maxillofacial Surgery Department of BSMMU during the study period with suspective cystic lesion in the maxillofacial region were included in the study. After clinical diagnosis with odontogenic cysts all the patients were treated surgically either under local anesthesia or under general anesthesia if required. Cystic lining was then sent for histopathological confirmation. Data were collected from a total of 76 patients with a clinical diagnosis of odontogenic jaw cysts. Of those, data of 14 patients were not included in the analysis (Histopathology showed no cystic lesion in 6 patients and non odontogenic cyst in 8 patients). Therefore data of a total of 62 patients were analyzed for the purpose of the study. The study protocol was explained to the patients in detail before obtaining the informed consent from the patients. Patients were allocated for the study.Outcome Variable: The following variable were recorded: gender, age, site of the lesion, swelling, tooth mobility, carious tooth, discolored tooth, missing tooth, radiological features, impacted tooth and correlation with histological types.Results: Out of 76 histopathology reports analyzed, odontogenic cyst found in 62 cases (82%). The mean patient age was 28.06 years. The cysts were slightly more prevalent in females (52%). Radicular cyst was the most prevalent histological type (56%), followed by dentigerous cyst (21%), odontogenic keratocysts (15%) and residual cysts (8%). The most common location of the odontogenic cysts were in the maxilla (n=35) than mandible (n=27).Conclusion: The most frequently occurring lesion was radicular cyst and the site was the anterior region of the maxilla. The dentigerous cyst and odontogenic keratocyst were the next most common lesions and preferred site was in the ramus and angular region of the mandible.Update Dent. Coll. j: 2015; 5 (2): 30-39

The term residual cyst is used for a cyst that has persisted after its associated tooth has been extracted or lost. Residual cysts are commonly observed in males and frequently found in the anterior region of the maxillary jaw. Residual cysts are among most common cysts of the jaws and are generally asymptomatic. We are reporting a case of residual cyst in the mandible of a 59-year-old male patient with emphasis on the pathogenesis, clinical, radiological features and treatment aspects.International Journal of Human and Health Sciences Vol. 02 No. 02 April’18.

Simple bone cyst (SBC) of the jaws is uncommon, representing approximately 1% of all jaw cysts. It is often accidentally discovered on routine dental examination as it is asymptomatic in most of cases. In this report, we discuss a case of SBC in a 16 years old female who presented in our department for correction of her mal-aligned teeth. On routine x-ray for orthodontic treatment, a well defined, unilocular radiolucent area approximately 3x1cm in size with scalloped borders on the left body of mandible expanding from distal surface of 34 to distal surface of 37 was discovered. Surgical exploration was required for both diagnostic and definitive treatment. The operative finding was hollow cavity without any epithelial lining.

Introduction A tendency to the increasing rate of follicular jaw cysts in children has been observed in Nizhny Novgorod region lately. Material and methods. 240 children (131 (54.6%) boys and 109 (45.4%) girls) with follicular jaw cysts aged 4 to 17 inclusive were treated at the maxillofacial department of Nizhny Novgorod Regional Children’s Clinical Hospital between 2003 and 2018. The follicular jaw cyst was diagnosed based on complaints, past medical history, and X‑ray examination (orthopantomography, computed tomography) done on the outpatient basis. All patients were operated using standard methods such as cystectomy, cystotomy, cystectomy with maxillary sinusotomy (when a cyst penetrates the maxillary sinus). Results. Within the last years, duration of hospitalization was reduced from 17.0±0.6 to 4.0±0.3 calendar days (2017) and to 4.8±0.4 calendar days (2018). The amount of immature permanent teeth increased as well. Conclusions. Thus, in spite of a greater number of children with follicular jaw cysts in Nizhny Novgorod region, it was possible to reduce duration of hospitalization and increase the number of preserved immature permanent teeth due to better diagnostics, earlier cyst detection and use of cystectomy.

Full textAbstract:
Összefoglaló. Bevezetés: Az állcsonti cysták helytálló diagnosztikája a klinikai, radiológiai és patológiai leletek együttes értékelésével lehetséges. Korábbi munkánk során többször tapasztaltuk a klinikoradiopatológiai kommunikáció és korreláció hiányát, és ez olykor inadekvát diagnózisok felállításához vezetett. Célkitűzés: Célunk ezen kommunikációs probléma mértékének becslése és annak bemutatása, hogy ez a hiányosság hogyan befolyásolhatja a diagnosztikát. Módszer: Korábbi, más célú retrospektív elemzés újraértékelése történt a klinikai (radiológiai) adatközlés, a revízió kapcsán módosuló diagnózisok számszerűsítése céljából, valamint további 3 egyetemi patológiai intézet 10-10 anonimizált leletének vizsgálata az adatközlések vonatkozásában. Eredmények: 2 intézményben 85 odontogen cysta diagnózisakor csupán a betegek életkora, neme volt 100%-osan ismert. A lokalizációra vonatkozó adekvát információ 62%-ban, a méretre vonatkozó csupán 29%-ban fordult elő a szövettani kérőlapokon. Összességében a diagnózist segítő releváns információt csak 52%-ban adtak meg. Az utólagos klinikoradiopatológiai korrelációra törekvő revízió során 38/85 esetben (45%) módosult a végső diagnózis kisebb vagy nagyobb mértékben. A megküldött leletek alapján a klinikai/radiológiai adatok közlése <50% és 100% közöttinek becsülhető más intézetekben is. Az 5 intézmény közül csak az egyikben utalt specializációra az, hogy minden leletet egy patológus véleményezett, általában sok patológus (n = 25) valamelyike véleményezte a kevés tömlőt (n = 105). A diagnózis kommunikáció hiányán alapuló kisiklásának lehetőségét 5 példával illusztráljuk: cysta radicularisként leletezett paradentalis, lobos follicularis és lateralis periodontalis cysta, ductus nasopalatinus cysta és radicularis cysta differenciáldiagnosztikáját példázó tömlő, valamint botryoid odontogen cysta kerül bemutatásra. Következtetés: Az odontogen tömlők precíz diagnosztikája mind a klinikai, mind a patológiai oldalról javítást igényel, amelynek egyik része az ilyen irányú képzés lehet. Orv Hetil. 2021; 162(12): 458–467. Summary. Introduction: Proper diagnosis of jaw cysts requires the parallel evaluation of clinical, radiological and histopathological findings. Lack of clinico-radio-pathological correlation can lead to inconsistent diagnoses. Objective: To evaluate the rate of lacking clinico-pathological communication and demonstrate how this may influence diagnostics. Method: Data of a former retrospective analysis were re-evaluated to quantify the lack of clinical data communicated to pathologists and estimate the rate of final diagnoses requiring alteration after review of all available clinical data. 10 anonymized reports on odontogenic cysts from 3 university pathology departments each were analysed for the lack of relevant clinical information. Results: Only the age and gender of patients were documented in 100% for 85 jaw cysts diagnosed in 2 departments of pathology. Adequate information about cyst localization and size were communicated in 62% and 29%, respectively. Overall, information relevant to the diagnosis was given in 52% of the cases. Revision based on clinico-radio-pathological correlation led to alterations of the diagnosis in 38/85 cases (45%). Based on reports from other institutions, the communication of clinical data is estimated to be between <50% and 100%. 25 pathologists were involved in reporting 105 cysts. 5 cases illustrate how diagnosis may fail without good communication: a paradental, an inflamed dentigerous and a lateral periodontal cyst, each misdiagnosed as radicular cyst; a cyst raising the differential diagnosis of nasopalatine duct versus radicular cyst; a botryoid odontogenic cyst. Conclusion: Proper diagnosis of jaw cysts requires improvements from both pathological and clinical sides, and could probably be improved through education. Orv Hetil. 2021; 162(12): 458–467.

Full textAbstract:
The dentigerous cyst is one of the most common developmental odontogenic cysts in the jaw. Occurrence of the bilateral dentigerous cyst is uncommon, and frequently associated with syndromes like basal cell nevus syndrome or cleidocranial dysplasia. There are few reports on the presence of bilateral dentigerous cyst in nonsyndromic patients, and most of these are associated with first and third molars. The reported case in this paper is bilateral dentigerous cysts associated with mandibular permanent second premolars, in the absence of any signs of syndrome. To our knowledge bilateral dentigerous cysts in these locations have not been previously reported.

Zysten und zystenähnliche Erkrankungen sind häufig auftretende Krankheiten des Ober- sowie Unterkiefers. Das Ziel der durchgeführten Studie war es, die Prävalenz und die topografische Verteilung von Kieferzysten für eine Leipziger Population darzustellen. Dafür wurden aus 4245 oralpathologischen Fällen der Jahre 2000 bis 2010 jene herausgefiltert, die einen Bezug zur Zielstellung aufwiesen. Es wurden Daten von 1336 Fällen (31,5%) ermittelt und retrospektiv ausgewertet. Die Auswertung erfolgte an Hand folgender Merkmale: Alter, histologische Beurteilung, Geschlecht, Größe, Lokalisation, Vorliegen eines Rezidivs, sowie entzündliche oder regressive Veränderung. Mit 932 Fällen stellten radikuläre Zysten die größte Gruppe (69,8%), gefolgt von follikulären Zysten (n=257; 19,2%), keratozystischen odontogenen Tumoren (n=62; 4,6%) sowie Residualzysten (n=54; 4,0%). Jeweils mit Anteilen kleiner als 1% wurden die folgenden Entitäten festgestellt: Ameloblastome (n=12), laterale parodontale Zysten (n=5), solitäre Knochenzysten (n=5), nasopalatinale Zysten (n=3), aneurysmatische Knochenzysten (n=2), paradentale Zysten (n=2), sowie Eruptionszysten als auch glanduläre odontogene Zysten (jeweils n=1). Mit 62,4% aller Patienten waren Männer signifikant häufiger betroffen (833 zu 502). 52,5% aller Zysten traten im Unterkiefer auf, damit signifikant öfter als im Oberkiefer (701 zu 603 Fälle). Die Altersspannweite reichte von einem bis zu 92 Jahren. Durchschnittliche trat eine Zyste erstmals mit 42,86 ± 17,30 Jahre (n=1335) auf. Weiterhin betrug die Durchschnittsgröße einer Zyste 1,17 ± 0,9 cm (n=1327). In 1101 Fällen (82,5%) konnte eine entzündliche Komponente histologisch nachgewiesen werden, vordergründig bei radikulären (n=932) sowie follikulären Zysten (n=106). Rezidive einer Erkrankung wurden in 17 Fällen beschrieben, besonders oft in keratozystischen odontogen Tumoren (n=8) sowie Ameloblastomen (n=4). Regressive Veränderungen konnten an 9 Zysten festgestellt werden, mit 4 Fällen am häufigsten bei keratozystischen odontogenen Tumoren. Die Prävalenz als auch die Verteilung der Kieferzysten in Leipzig zeigte sich in weiten Teilen sehr ähnlich zu den aus anderen Populationen.

Full textAbstract:
Bakgrund: Vid diagnostik av käkbenslesioner skickas ibland en remiss till röntgenspecialist för ett utlåtande. Röntgenspecialisten ger en eller flera tentativa diagnoser vilka kan underlätta vid beslut om behandling. Efter behandlingen skickas en biopsi till patolog för att erhålla en patologanatomisk diagnos. Syftet med denna studie är att 1) utreda hur väl tentativa röntgenologiska diagnoser överensstämmer med patologanatomiska diagnoser av käkbenslesioner och 2) utvärdera hur ofta röntgenutlåtanden kan leda till felaktig behandling av käkbenslesioner.Material och metod: Röntgenutlåtanden och motsvarande patologanatomiska diagnoser jämfördes retrospektivt under en tioårsperiod för nio vanliga käkbenslesioner. För varje käkbenslesion räknades antalet korrekta respektive inkorrekta röntgenologiska diagnoser som erhållits. Utöver detta jämfördes även den förväntade behandlingen av varje tentativ röntgendiagnos med den förväntade behandlingen av den korrekta patologanatomiska diagnosen. Utifrån detta gjordes sedan en bedömning av huruvida röntgenutlåtandet kunde leda till underbehandling, korrekt behandling eller överbehandling. Resultat: Röntgendiagnoserna överensstämde med de patologanatomiska diagnoserna i 191 av 394 fall (48%). Därutöver gav 61 röntgenutlåtanden (16%) den korrekta diagnosen tillsammans med en eller flera inkorrekta diagnoser. 142 utlåtanden (36%) gav endast en eller flera inkorrekta diagnoser. Drygt en fjärdedel av alla röntgenutlåtanden bedömdes kunna leda till felaktig behandling. Konklusion: Resultaten indikerar en anmärkningsvärd diskrepans mellan de tentativa röntgendiagnoserna och de patologanatomiska diagnoserna av de undersökta käkbenslesionerna. När röntgenspecialisten ger fler än en tentativ diagnos finns en ökad risk för överbehandling vilket kan leda till onödigt lidande för patienten samt en ökad kostnad för både patienten och samhället. Baserat på dessa resultat bör röntgenspecialisternas rutiner för hur många tentativa diagnoser de anger i sina röntgenutlåtanden ses över.Background: When diagnosing jaw lesions, a referral may be sent to a radiologist for a radiographic report. The radiologist offers one or several tentative diagnoses, which help form the basis for treatment. After treatment a biopsy is sent to a pathologist for a pathoanatomical diagnosis. The aim of this study is to 1) determine the correspondence between tentative radiographic diagnoses and pathoanatomical diagnoses of jaw lesions and 2) evaluate how frequently radiographic reports may lead to incorrect treatment of jaw lesions. Materials and methods: Radiographic reports and pathoanatomical diagnoses of nine common jaw lesions were compared retrospectively over a ten-year period. The numbers of correct and incorrect tentative radiographic diagnoses were counted for each lesion. In addition, the expected treatments of the tentative radiographic diagnoses were compared with the expected treatments of the correct pathoanatomical diagnoses. Each report was then categorized as leading to undertreatment, correct treatment or overtreatment.Results: The radiographic reports corresponded with the pathoanatomical diagnoses in 191 out of 394 cases (48%). In addition, 61 radiographic reports (16%) stated the correct diagnosis along with one or several incorrect diagnoses. 142 reports (36%) only stated one or several incorrect diagnoses. Just over a quarter of the radiographic reports were deemed to lead to incorrect treatment. Conclusion: The results indicate a remarkable discrepancy between tentative radiographic diagnoses and pathoanatomical diagnoses for the studied jaw lesions. There is a tendency towards overtreatment when more than one tentative diagnosis is stated in the radiographic reports. Overtreatment may lead to unnecessary suffering for the patient and financial loss for both the patient and society. Based on these results, radiologists should review their practice of stating several tentative diagnoses in their reports.

Studies demonstrate that galectins are involved in the development of immunoinflammatory response, by regulation of homeostasis and immune cell functions. However, the function of these lectins in the development of periapical lesions are scarce in the literature. The objective of this study was to evaluate, through immunohistochemistry, the expression of galectinas -1, -3 and -7 in periapical granulomas (PGs), radicular cysts (RCs), and residual radicular cysts (RRCs), related this with morphological parameters (intensity of the inflammatory infiltrate and the thickness of the cystic epithelial lining). The sample consisted of 20 periapical granulomas (PGs), 20 radicular cysts (RCs), and 20 residual radicular cysts (RRCs) were submited to immunohistochemistry. The inflammatory and epithelial cells were quantified from nuclear and/or cytoplasmic/membrane expression and their percentage submited for statistical evaluation. The results for the morphological analysis revealed that 100% of GPs and 80% of CRs showed an intense inflammatory infiltrate (grade III), and to CRRs, 60% had a mild inflammatory infiltrate (grade I). The analysis of epithelial lining in cystic lesions showed that atrophic ephitelium was observed in 65% of CRRs and 50% of the RCs, the hyperplastic ephitelium was demonstrated, respectively, in 50% and 35% of the RCs of CRRs. Immunohistochemical evaluation of each galectin in connective tissue demonstrated that GPs exhibited higher expression of galectin -1 in relation to RCs and CRRs in both components (nucleus and cytoplasmic/membrane) of inflammatory cells (p <0.05). Additionally, lesions that exhibit inflammation grade II had an increased expression of galectin-1 in both cell components (p <0.05). Galectin-3 showed no differences statistically significant in inflammatory cells of connective tissue (p> 0,05). In Galectin-7, GPs showed a higher immunoreactivity of this protein in cytoplasmic/membrane component, compared to CRs and CRRs (p <0.05) and independently of the type of lesion, those with inflammatory infiltrate grade III had greater immunoreactivity of galectin-7 (p <0.05). In the epithelial lining, galectins -1 and -3 showed no statistically significant differences of immunoreactivity (p> 0.05). However, the immunohistochemical expression of galectin-7 revealed that epithelial lining of CRRs showed a higher percentage of nuclear expression than CRs epithelial lining (p = 0.014). Lesions with hyperplastic epithelium showed a greater cytoplasmic/membrane positivity than lesions with atrophic epithelium (p=0.020). Positive correlations were observed to each galectin on epitelial and connective tissues. In addition, positive correlations were observed between galectins -1 and -7 into connective tissue (p <0.001), independent the type of lesion. In conclusion, the results of this study show the involvement of these proteins in the modulation of immunoinflammatory response among periapical lesions.
Estudos revelam que as galectinas exercem importante papel na resposta imunoinflamatória, através da regulação da homeostase e em funções de células imunes. Todavia, a participação destas proteínas no desenvolvimento de lesões periapicais ainda não foi esclarecida. O objetivo do estudo foi avaliar, por meio de imunoistoquímica, a expressão das galectinas -1, - 3 e -7 em granulomas periapicais (GPs), cistos radiculares (CRs) e cistos radiculares residuais (CRRs), correlacionando-as com parâmetros morfológicos (intensidade do infiltrado inflamatório e padrão de revestimento epitelial). Amostra composta por 20 GPs, 20 CRs e 20 CRRs foi submetida à imunoistoquímica. As células inflamatórias e epiteliais foram quantificadas à partir da imunoexpressão nuclear e/ou citoplasmática/membranar e dados seus percentuais foram sumetidos à avaliação estatística. Os resultados para a avaliação morfológica revelaram que 100% dos GPs e 80% dos CRs apresentaram um intenso infiltrado inflamatório (grau III), e para os CRRs, 60% apresentaram um infiltrado inflamatório leve (grau I). Na análise do revestimento epitelial das lesões císticas, o padrão atrófico foi observado em 65% dos CRRs e 50% dos CRs, já o hiperplásico, em 50% dos CRs e 35% dos CRRs. A avaliação imunoistoquímica de cada galectina no componente conjuntivo, demonstrou que os GPs apresentaram uma maior expressão da galectina -1 em relação aos CRs e CRRs tanto no núcleo quanto no componente citoplasmático/membranar das células inflamatórias (p< 0,05). Adicionalmente, as lesões que apresentaram inflamação grau III tiveram uma maior expressão da galectina-1 em ambos componentes celulares (p<0,05). A galectina-3 não demonstrou diferenças estatisticamente significativas nas células inflamatórias do componente conjuntivo (p> 0,05). Para a galectina-7, os GPs apresentaram uma maior imunoexpressão desta proteína no componente citoplasmático/membranar, comparadas aos CRs e CRRs (p<0,05) e independente do tipo de lesão, as que apresentaram infiltrado inflamatório grau III tiveram maior imunoexpressão da galectina-7 (p<0,05). No componente epitelial, as galectinas -1 e -3 não apresentaram diferenças estatisticamente significativas de imunoexpressão (p> 0,05). Todavia, a imunoexpressão da galectina-7 revelou que o revestimento epitelial de CRRs apresentaram um maior percentual de positividade nuclear quando comparado ao revestimento dos CRs (p = 0,014). Lesões com epitélio hiperplásico exibiram maior positividade citoplasmática/ membranar quando comparadas às de epitélio atrófico (p=0,020). Foram observadas correlações positivas para cada uma das galectinas no componente epitelial e conjuntivo de todas as lesões. Adicionalmente, foram observadas correlações positivas entre as galectinas -1 e -7 no tecido conjuntivo (p < 0,001), independente do tipo de lesão. Em conclusão, os resultados do presente estudo evidenciam a participação destas proteínas na modulação da resposta imunoinflamatória entre lesões periapicais.

Introduction: Gorlin syndrome (GS) also known as Nevoid Basal Cell Carcinoma Syndrome, is a rare disease resulting from mutations in Patched-1 gene and characterized by triad of disorders comprising multiple basal cell carcinomas, numerous keratocystic odontogenic tumors (KOT) and skeletal abnormalities. About 90% of patients develop KOTs in gnathic bones, preferably in the posterior mandible, presenting radiographically as radiolucent lesions uni- or multilocular. Studies suggests that KOTs associated with GS (KOTGSs) have distinct and more aggressive behavior compared to those who developing sporadically (KOTSPs). Objectives: This study aimed at comparing clinical, histopathological and immunohistochemical features of KOTSPs and KOTGSs from different institutions in Brazil and abroad, and understand the role of proteins associated with proliferation/cell cycle (p53, p63 and Ki-67), the alpha-smooth muscle actin (α-SMA) and syndecan-1 (CD138) in an attempt to associate the expression with biological behavior of KOTs. Methodology: Were previously reviewed and selected 30 KOTGSs and 8 KOTSPs, in which were performed qualitative and semi-quantitative analysis histopathological and immunohistochemical to p53, p63, Ki-67, SMA and CD138. Results: 30 cases of KOTGSs were obtained from 12 patients with GS, 5 females (41.66%) and 7 men (58.33%); whereas in group of KOTSPs, 5 cases (62.50%) was in females and 3 males (37.50%). About 58.33% of patients with GS had more than one lesion throughout life. The average age of individuals with GS was 14.66 ± 16.81 years, while in patients with KOTSPs was 41 ± 39.59. The predominant radiographic pattern was radiolucent unilocular, preferably affecting the posterior mandible. Histopathological features in both groups was analyzed, and the most frequent was pleomorphism in KOTGSs. In addition, there was increased expression of p53 and p63 in KOTGSs and similar expression of SMA and Ki-67 between groups. It was also observed that there was a lower reactivity for CD138 in the basal epithelial layer of KOTGSs and stromal expression of CD138 was similar between the groups. Conclusions: Agressiveness of KOTGSs can be explained by increased cellular pleomorphism rate and expression of p53 and p63 and tendency to loss of syndecan-1 expression compared to KOTSPs.
Introdução: A Síndrome de Gorlin (SG) também conhecida como Síndrome do Carcinoma Nevóide Basocelular, é uma doença rara resultante de mutações no gene Patched-1 e caracterizada por uma tríade de alterações que inclui múltiplos carcinomas basocelulares, numerosos tumores odontogênicos queratocísticos (TOQs) e anormalidades esqueléticas. Cerca de 90% dos portadores desenvolvem TOQs no interior dos ossos gnáticos, preferencialmente na região posterior da mandíbula, apresentando-se radiograficamente como lesões radiolúcidas uni ou multiloculares. Estudos têm sugerido que os TOQs associados à SG (TOQSG) apresentam comportamento distinto e mais agressivo em comparação àqueles que desenvolvem-se de modo esporádico (TOQEs). Objetivos: O presente estudo teve como objetivo analisar comparativamente os aspectos clínicos, histopatológicos e imuno-histoquímicos de TOQEs e TOQSGs oriundos de diferentes instituições do Brasil e do exterior, além de entender o papel de proteínas associadas com proliferação/ciclo celular (p53, p63 e Ki-67), da actina de músculo liso-alfa (α-SMA) e da proteína sindecano-1 (CD138), na tentativa de associar a expressão das mesmas com o comportamento biológico dos TOQs. Metodologia: Foram previamente revisados e selecionados 30 TOQSGs e 8 TOQEs, nos quais foram realizadas análises qualitativas e semi-quantitativas histopatológicas e imuno-histoquímicas para p53, p63, Ki-67, AML e CD138. Resultados: Trinta casos de TOQSGs foram obtidos de 12 pacientes com SG, 5 do gênero feminino (41,66%) e 7 do gênero masculino (58,33%); ao passo que no grupo dos TOQEs, 5 casos (62,50%) acometeram o gênero feminino e 3 o masculino (37,50%). Cerca de 58,33% dos pacientes com SG apresentaram mais de uma lesão ao longo da vida. A média de idade dos indivíduos com SG foi de 16,81 anos ± 14,66 enquanto dos portadores de TOEs foi de 41 anos ± 39,59. O padrão radiográfico predominante foi o radiolúcido unilocular, afetando preferencialmente a região posterior de mandíbula. Foram avaliadas as características histopatológicas de ambos os grupos de lesões, sendo o pleomorismo celular mais frequente nos TOQSGs. Além disso, observou-se maior expressão de p53 e p63 nos TOQSG e expressão similar de AML e Ki-67 entre os grupos. Observou-se ainda que houve menor reatividade para CD138 no estrato epitelial basal dos TOQSGs e a expressão estromal de CD138 foi similar entre os grupos analisados. Conclusões: A maior agressividade dos TOQSGs pode ser explicada pela maior taxa de pleomorfismo celular, maior expressão de p53 e p63 e tendência à perda de expressão de sindecano-1 quando comparados aos TOQEs.

Johannesburg, 2015Objectives: To analyse the clinico-pathological features of orthokeratinised jaw cysts (OJCs) and to determine whether human papillomavirus (HPV) DNA can be detected in OJCs. Material and methods: The clinical and radiological information of 30 patients diagnosed with OJCs were reviewed and the respective histology samples were studied for light microscopic features characteristic of HPV infection. The 30 OJCs were further evaluated for the presence of HPV by using consensus HPV polymerase chain reaction (PCR). Results: Patients with OJC ranged from 13 to 71-years (mean, 30.9 years; ± 12.9 years). There was a predilection for males (21/30). Most OJCs were found in the mandible (80%) and 44.8% were associated with an impacted tooth. Koilocyte-like characteristics were identified in 70% of cases, while 43.3% of cases showed a verruciform pattern of hyperkeratosis. All 30 OJCs were negative for HPV-DNA. Conclusion: HPV infection does not appear to play a role in the OJC and is not responsible for the wart-like histological changes that may be encountered in OJCs.

the branch of DentistryOrthokeratinised jaw cyst (OJC) is an entity distinct from odontogenic keratocyst (OKC) but that has not been fully characterised at the molecular level. The aim of this study was to compare the proliferative activity between the epithelial linings of OKC and OJC by immunohistochemical staining for Ki-67 and cyclin D1. The total numbers of Ki-67 and cyclin D1 positively (+) stained cells/10 consecutive lengths of a light microscope calibration ruler were counted for each case (OKC, n=15; OJC, n=15) and statistically compared in the basal compartment, suprabasal compartment and full thickness of the cyst lining between the 2 cyst types. OJC showed significantly fewer Ki-67+ cells and cyclin D1+ cells than OKC, consistent with the clinically more indolent behaviour of the OJC. Ki-67 expression was mainly detected in the suprabasal compartment in OKC. Expression of Ki-67 was more uniform in OJC and notably without a significant predilection for the suprabasal compartment. The accumulation of Ki-67 positive cells suprabasally in OKC raises the possibility that a process of asymmetrical cell division may be operational in OKC. Expression between Ki-67 and cyclin D1 differed significantly both quantitatively and by distribution pattern in OKC and OJC, which suggests that the presence of the cyclin D1 protein may not necessarily reflect production of this molecule by cycling cells in OKC and OJC.

Full textAbstract:
AbstractCysts of the Oro-Maxillofacial region have common occurrence in comparison to any other parts of the body. These can be true cysts or pseudocysts and can be found in the jaw bones or in the soft tissues. Cysts are of various types, and over the years, various classifications are put forward, which are helpful to identify each cyst, based on its origin and its clinical and histopathological presentation. Based on the classification, one can also decide the treatment plan accordingly. The classifications are given by various researchers and also by WHO. In this chapter, various odontogenic and nonodontogenic cysts and their treatment aspect are discussed in detail.

Full textAbstract:
Odontogenic cysts and tumours arise from inclusion of tooth-forming epithelium and mesenchyme in the jaw bones during development. Cysts also arise from non-odontogenic epithelium trapped during fusions or from vestigial structures. In addition, bone cysts that can arise at other skeletal sites may also occur in the jaws. Odontogenic cysts and tumours may be classified according to their putative developmental origins and biology. The classification of jaw cysts is shown in Fig. 6.1. Odontomes are hamartomatous developmental lesions of the tooth-forming tissues. Odontogenic tumours are uncommon and are usually benign. Ameloblastoma is the most common odontogenic tumour and is described in detail. The other odontogenic tumours are rare and only the principal features are presented. Very rare congenital lesions of possible odontogenic origin are mentioned in the final section. A cyst may be defined as pathological cavity lined by epithelium with fluid or semi-fluid contents. However, clinically, the term encompasses a broader range of benign fluid-filled lesions, some of which do not possess an epithelial lining. The preferred definition is, therefore, ‘a pathological cavity having fluid or semi-fluid contents that has not been created by the accumulation of pus’. Cysts are commonly encountered in clinical dentistry and are generally detected on radiographs or as expansions of the jaws. Most cysts have a radiolucent appearance and are well circumscribed, often with a corticated outline. At least 90% of jaw cysts are of odontogenic origin. The clinico-pathological features of jaw cysts are summarized in Table 6.1. The incidence of the four most common jaw cysts are provided in Table 6.2. The epithelial lining of odontogenic cysts originates from residues of the tooth-forming organ. • Epithelial rests of Serres are remnants of the dental lamina and are thought to give rise to the odontogenic keratocyst, lateral periodontal, and gingival cysts. • Reduced enamel epithelium is derived from the enamel organ and covers the fully formed crown of the unerupted tooth. The dentigerous (follicular) and eruption cysts originate from this tissue, as do the mandibular buccal and paradental cysts. • Epithelial rests of Malassez form by fragmentation of Hertwig’s epithelial root sheath that maps out the developing tooth root. Radicular cysts originate from these residues.
