ABSTRACT

Odontogenic lesions are a heterogeneous group of diseases that presents differences in their biological behavior and the occurrence of variable inductive interactions. Calcifying odontogenic cyst (COC), or Gorlin's cyst, is a well-recognized example of these lesions. We describe a case of COC with AOT-like areas and highlights its morphological diversity. A 60-year-old pheoderma man presented with a large swelling in the anterior buccal region of the mandible. Panoramic radiography revealed a well-defined, unilocular, radiolucent lesion associated with important root resorption. Complete enucleation of the lesion was performed and the histopathological findings met the criteria for the diagnosis of COC, although the cyst exhibited unusual AOT-like features. The patient has been recurrence free for 6 months after surgery. COCs with AOT-like features are rare, and reflect the multipotentiality and complexity of the inductive effects of the odontogenic epithelium with the ectomesenchyme. Enucleation seems to be the most indicated treatment, similar to classical COC (AU)


As lesões odontogênicas são um grupo heterogêneo de patologias que apresentam diferenças no seu comportamento biológico, e ocorrência de interações indutivas variáveis. O cisto odontogênico calcificante (COC), ou cisto de Gorlin, é um exemplo bem conhecido destas lesões. Descrevemos um caso de COC com áreas adenomatóides e destacamos a sua diversidade morfológica. Paciente do sexo masculino, 60 anos de idade, apresentou um aumento de volume na região anterior da mandíbula. A radiografia panorâmica revelou uma lesão bem definida, unilocular e radiolúcida associada a uma reabsorção radicular importante. A enucleação completa da lesão foi realizada e os achados histopatológicos preencheram os critérios para o diagnóstico de COC, embora o cisto exibisse características adenomatóides pouco usuais. O paciente permanece livre de recidivas durante 6 meses após a cirurgia. Os COCs com características adenomatóides são raros, e refletem a multipotencialidade e complexidade dos efeitos indutivos do epitélio odontogênico com o ectomesênquima. A enucleação parece ser o tratamento mais indicado, semelhante ao COC clássico. (AU)

ABSTRACT

Nas últimas décadas a sociedade como um todo foi impactada das mais diversas maneiras pelo uso da tecnologia. Inteligência Artificial é o termo usado para se referir a algoritmos que permitem com que computadores realizem tarefas que exigem a percepção humana para serem feitas. O presente estudo tem o objetivo de relatar o que há de mais recente na literatura sobre o tema de Inteligência Artificial na Odontologia, mais propriamente na área de Patologia Oral e Maxilofacial, e realizar um piloto para diferenciação de lesões utilizando software gratuito. Para realizar o estudo, foram selecionados casos específicos dos últimos 20 anos do Serviço de Patologia Oral e Maxilofacial da Universidade de São Paulo, sendo estes casos de lesões benignas e malignas para comparação e poder elucidar como a patologia através da IA pode ser realizada.). Ao finalizar este processo, o modelo de ML identificou as imagens que foram pedidas para que o software analisasse e uma taxa de acurácia foi obtida, que neste caso foi de 98% de assertividade de que a imagem colocada era referente a uma imagem histológica de uma lesão maligna e de 97% para a lesão benigna (neste caso, um carcinoma epidermoide e um fibroma respectivamente). O estudo concluiu que a IA é pouca explorada tanto no âmbito rotineiro quanto acadêmico e que novas pesquisas devem ser realizadas com incentivo a fim de produzir literatura, mostrar aos estudantes o que pode ser realizado com tecnologia apropriada e agilizar o processo diagnóstico, facilitando a vida do profissional e de todo o sistema que o envolve.

ABSTRACT

Objetivo: Investigar as percepções e atitudes de pais/responsáveis sobre cuidados relacionados à saúde bucal das crianças por meio de um estudo descritivo. Métodos: Foi aplicado um questionário semiestruturado aos pais/responsáveis de crianças atendidas nas clinicas de Odontopediatria da Pontifícia Universidade Católica de Minas Gerais (PUC-MG) em 78 pais/responsáveis. O questionário apresentava questões sociodemográficas, assim como questões específicas relacionadas aos cuidados e atitudes para a saúde bucal de seus filhos/crianças. Análise descritiva e exploratória, por meio de médias, frequências e porcentagens foram realizadas e ilustradas por meio de figuras. Resultados: Embora a maioria dos entrevistados tenha alegado já terem recebido informações a respeito dos cuidados bucais infantis, pais/responsáveis consideraram o momento propício para a primeira visita ao dentista somente após o 1º ano de vida, período inadequado para o aleitamento materno, além da utilização inadequada de chupeta e mamadeira por longos períodos e do período para a inserção do hábito da escovação. Além disso, temáticas relacionadas à erosão dentária, teste da linguinha e a importância do íon fluoreto para a saúde bucal foram os assuntos classificados com mais dúvidas. Conclusão: Em geral, as atitudes dos pais e responsáveis não se mostraram adequadas, apesar de possuírem informações prévias no que tange a saúde bucal das crianças. Com isso, verifica-se a necessidade de enfatizar mais a fundo questões referentes a esta temática e diferentes meios para a difusão deste tipo de informação.


Aim: To investigate the perceptions and attitudes of parents/guardians about oral health care for children through a descriptive/cross-sectional study. Methods: A semi-structured questionnaire was applied to 78 parents/guardians of children seen at the Pediatric Dentistry Clinics of the Pontific Catholic University of Minas Gerais (PUC-MG). The questionnaire presented sociodemographic questions, as well as specific questions related to the care and attitudes towards the oral health of their children. Exploratory and descriptive analyses by means of means, frequencies,and percentages were performed and illustrated in figures. Results: Although most of the interviewees claimed to have already received information regarding children's oral care, they considered the proper time for the first visit to the dentist only after the 1st year of life, an inadequate period for breastfeeding, as well as the inappropriate use of pacifiers and bottles for long periods and an improper period for the insertion of the habit of tooth brushing. Furthermore, issues related to dental erosion, the tongue test, and the importance of fluoride ions for oral health were the subjects classified with the most doubts. Conclusion: In general, the attitudes of parents and guardians proved to be inappropriate, although they have previous information regarding the oral health of children. Thus, there is a need to offer a more in-depth emphasis on issues related to this theme and different means through which to disseminate this type of information.

ABSTRACT

Tumors of the maxillomandibular complex are a heterogeneous group of lesions with a wide spectrum of clinical and histopathological characteristics. Aim: To evaluate the prevalence of odontogenic and non-odontogenic tumors associated with maxillary bones in a Reference Center for Oral Lesions. Methods: A cross-sectional study based on the medical records of a Reference Center for Oral Lesions at the State University of Feira de Santana, from 2006 to 2018. The data was initially analyzed in a descriptive manner. For bivariate analysis, Pearson's chi-square test was applied. The level of significance was set at 5%, where p≤ 0.05 is considered significant. Results: The prevalence of tumors was 2.27%. The average age of the individuals was 22.2 (± 15.1) years, the majority being up to 39 years (79.59%) and female (69.40%). A statistically significant difference was observed in relation to age (p = 0.00), as well as regarding the location of tumors in the anterior or posterior region (p = 0.02). Odontogenic tumors were benign, with odontoma being most frequent (46.90%), followed by ameloblastoma (16.30%). As for the non-odontogenic, neurofibroma (4.10%) and osteoma (4.10%) were the most common across the benign, while osteosarcoma accounted for 6.10% of cases. Conclusion: Odontogenic tumors were the most frequent in women, with age up to 39 years, odontoma being most common in the posterior region of the mandible. Among nonodontogenic tumors, central neurofibroma and osteoma were the most common. Osteosarcoma was more frequent in men over 40 years old and in the mandible region

ABSTRACT

ABSTRACT: Introduction: A telemedicine program in oral pathology (TOP) and a preventive oral examination (POE) to identify oral lesions was implemented in Hualqui, Chile. The objective of this study is to describe the results of the TOP plus POE strategy at CESFAM Hualqui, Chile, during the period of 2016 to 2019. Materials and methods: A prospective cohort study was conducted with 152 Hualqui patients between 2016 and 2019. The following variables were recorded: diagnosis; injury diagnosis dates; date of teleconsultation; date and response of the specialist and subsequent control; waiting time for response (WTR) and waiting time for attention (WTA). Results: The WTR was 19.7 ± 12.8 days and WTA presented a median of 20 days (1−125) days. A total of 45 different oral pathologies were identified, the most frequent being stomatitis 8.6% (13), fibroma 8.6% (13) and mucocele 7.9% (12), and among the least frequent highlights three cases of oral cancer. Conclusions: The waiting periods until a response from the specialist and then until the face-to-face control were around 3 weeks each, most of the cases were identified through POE and correspond mostly to benign pathologies.

ABSTRACT

ABSTRACT Objective: To compare the agreement of clinical and radiographic diagnosis with the histopathological diagnosis in fibro-osseous lesions of the jaws. Material and Methods: An analytical and exploratory study was made based on systematic collected data, carried out in the laboratory of surgical pathology of a public Dental School. There were evaluated cases of fibrous dysplasia (FD), cemento-osseous dysplasia (COD) and ossifyng fibroma (OF), diagnosed by clinical, radiographic (panoramic and periapical radiography), and histopathological analysis, in a period of 12 years (from March 2001 to June 2013). Descriptive and inferential statistics (Fisher's exact test) were obtained. Results: Ninety-six cases of FOLs were evaluated. The radiographic aspects of the FOLs studied did not differ significantly (p=0.09). Radiolucent lesions were the least frequent, corresponding to approximately 13.5% of radiographic findings. Mixed lesions and radiopaques were more present, how they were COD and FD, respectively. The more aggressive variation of OF (Juvenile Ossifying Fibroma - JOF) was less frequent among the pathologies evaluated. In approximately 61.46% of the cases clinical and radiographic diagnosis were confirmed by histopathological diagnosis of FOLs. The highest agreement and the highest disagreement were observed in COD cases (40.7% and 62.2%, respectively). Conclusion: FOLs of the maxillaries represent a group of lesions in which the establishment of the clinical and radiographic diagnosis supported by the histopathological confirmation is critical and challenging.

ABSTRACT

ABSTRACT Objective: To determine the frequency of oral potentially malignant disorders and Oral Squamous Cell Carcinoma (OSCC) and evaluate the consistency between their clinical and pathological features. Material and Methods: This retrospective study was conducted on records with a diagnosis of oral leukoplakia, oral erythroplakia, erythroleukoplakia, actinic cheilitis, lichen planus, and OSCC in the Pathology Department of Kerman dental school from September 1997 to September 2017. Data were analyzed in SPSS 21 at the significance level of ≤5%. Results: There were 378 cases of oral potentially malignant disorders and 70 cases of OSCC with a mean age of 46.82 ± 15.24 years. Buccal mucosa was the most frequent site, and lichen planus the most common lesion. Females were significantly older than males in leukoplakia and carcinoma in situ lesions. Clinical diagnosis and histopathology were consistent in 69.03% of cases. Conclusion: Clinical and histopathological diagnoses were consistent in 69.03% of records. The highest degree of clinical compliance with histopathology was observed in OSCC. Dentists should pay attention to oral potentially malignant disorders for early diagnosis to prevent their transformation to malignancy.

ABSTRACT

ABSTRACT Objective To evaluate the effect of the COVID-19 impacts on the activities of researchers in the field of Oral Medicine (OM) and Oral Pathology (OP). To assess the research activities and training of human resources by Brazilian productivity fellows in research (BPFR) in OM and OP in the COVID-19 Era. Material and Methods Thirty-six BPFR in OM and OP areas, funded by National Council for Scientific and Technological Development (CNPq), received a virtual structured questionnaire by e-mail, on the Google Forms (Google®) platform, with questions regarding research activities and training of human resources (supervision of undergraduate and postgraduate students), during the COVID-19 pandemic. From the thirty-six BPFR in OM and OP, twenty-seven (75.0%) answered the questionnaire. Results Most of them were males (n=20; 74.1%) and were distributed in four Brazilian regions and ten states of the federation, including the Federal District. Twenty-four (88.9%) BPFR reported having suspended clinical activities, while sixteen (59.3%) answered that histopathology practices are suspended. Twenty-five (92.6%) BPFR mentioned difficulties in conducting research projects and 55.5% stated having no difficulties in the supervision of undergraduates, master's and PhD students. Conclusion The current scenario may significantly impact the diagnosis of oral diseases in Brazil. Moreover, a decrease in the scientific production of BPFR in OM and OP in the coming years is also considered.

ABSTRACT

ABSTRACT Objective: To evaluate the intra-examiner and inter-examiner reliability of linear and curvilinear measurements for the complete assessment of implant sites and jaw pathologies using Cone-Beam Computed Tomography (CBCT). Material and Methods: Fifty cone-beam computed tomographic images of patients were retrieved from the archives of Dentomaxillofacial Radiology. CBCT images taken for implant planning and evaluation of intrabony jaw pathologies (benign cyst/tumor) were included. Two expert oral and maxillofacial radiologists analyzed the images independently and made the measurements. The images for implant planning were analyzed for width, the height of the edentulous site, and the qualitative analysis of bone in the region. Jaw pathologies were assessed for linear dimensions and curvilinear measurements. Results: The inter-observer measurement error for implant site analysis ranged from 0.12 to 0.42 mm with almost perfect agreement (ICC: 0.94 to 1). The inter-observer measurement error for jaw pathology was 0.09 to 0.25 mm (ICC: 0.98-1). Curvilinear measurements showed perfect agreement between the observers. The intraobserver reliability for the various parameters used for the assessment of the implant site and jaw pathologies indicated almost perfect agreement. Conclusion: Reliability between the radiologists is high for various measurements on CBCT images taken for implant planning and jaw pathologies.

ABSTRACT

Resumen Introducción: La trombocitopenia inmune primaria (PTI) es una enfermedad caracterizada por la destrucción acelerada de plaquetas o la producción inadecuada de estas. Se puede clasificar según su etiología en primaria y secundaria. Métodos: Se presenta el caso de un paciente sexo masculino de 30 años de edad, que acude al servicio de urgencia dental del Hospital Barros Luco, por lesiones hemorrágicas mucosa oral y pequeñas manchas rojas en manos, brazos y espalda, de veinticuatro horas de evolución, asintomáticas y sin causa atribuible. Al examen físico se corrobora la presencia de múltiples vesículas hemorrágicas en región bucal y petequias en las zonas descritas. Se realiza diagnóstico presuntivo de PTI que se confirma al obtener un recuento plaquetario (RP) de 2000 uL. Se deriva a medicina interna para evaluación y manejo. La literatura describe que para confirmar esta enfermedad se requiere una historia clínica exhaustiva, descartar una patología sistémica o infecciosa previa y pruebas de laboratorio que evidencien recuento normal de células sanguíneas con una trombocitopenia marcada. Conclusión: El odontólogo tiene un rol significativo en el manejo multidisciplinario en este tipo de cuadros donde el conocimiento de manifestaciones orales de enfermedades sistémicas es de vital importancia para el diagnóstico, derivación y posterior tratamiento de estas.


Abstract Introduction: Primary immune thrombocytopenia (ITP) is a disease characterized by accelerated destruction of platelets or inadequate production of platelets. It can be classified according to its etiology in primary and secondary. Methods: We present the case of a 30-year-old male patient, who comes to the dental emergency service of the Barros Luco Hospital, for oral mucosa hemorrhagic lesions and small red spots on the hands, arms and back, 24 hours of evolution, asymptomatic and without attributable cause. Physical examination corroborates the presence of multiple hemorrhagic vesicles in the oral region and petechiae in the areas described. A presumptive diagnosis of ITP is made and confirmed by obtaining a platelet count (RP) of 2000 uL. He is referred to internal medicine for evaluation and management. The literature describes that confirming this disease requires an exhaustive medical history, ruling out a previous infectious or systemic pathology, and laboratory tests that show normal blood cell counts with marked thrombocytopenia. Conclusions: The dentist has a significant role in multidisciplinary management in this type of condition, where knowledge of oral manifestations of systemic diseases is of vital importance for the diagnosis, referral and subsequent treatment of these. Oral manifestations in primary immune thrombocytopenia patients. Case report

ABSTRACT

El quiste dentígero y el ameloblastoma son patologías con poca sintomatología y características clínicas, las cuales son evidentes cuando las lesiones alcanzan dimensiones mayores y esto sucede cuando llevan un tiempo considerable de evolución, por lo cual son descubiertas generalmente en exámenes radiográficos de rutina. El presente artículo describe los hallazgos histológicos y su correlación clínico-patológica y radiográfica entre el quiste dentígero y el ameloblastoma, lo que permite un diagnóstico y un plan de tratamiento. Se presentan dos casos de pacientes masculinos, de 12 y 15 años, que asisten a consulta a la Facultad de Odontología de la Universidad de Cartagena en Colombia, por presentar tumefacción en zona de sínfisis mandibular y en zona de tercer molar inferior derecho. Se especifican hallazgos clínicos, radiográficos e histológicos. Para llegar a los diagnósticos de quiste dentígero y ameloblastoma se deben tener en cuenta todos los hallazgos del examen clínico y radiográfico, pero debe primar el dictamen del examen histopatológico para determinar un tratamiento adecuado. (AU)


Dentigerous cysts and ameloblastomas present with few symptoms, and clinical characteristics present when lesions reach larger dimensions following a considerable length of evolution, and thus, these lesions are often discovered in routine radiographic examinations. This study describes the histological findings and clinical, pathological, and radiographic correlations between dentigerous cysts and ameloblastomas which aid in diagnosis and treatment planning. Two male patients, aged 12 and 15, were attended at the Faculty of Dentistry of the Cartagena University in Colombia due to swelling at the mandibular symphysis and lower right third molar area. The clinical, radiographic and histological findings are described. Clinical and radiographic findings must be taken into account to diagnose dentigerous cysts and ameloblastomas, with histopathological examination providing the definitive diagnosis and allowing adequate patient management.

ABSTRACT

ABSTRACT Antiresorptive therapy is the main form of prevention of osteoporotic or fragility fractures. Medication-related osteonecrosis of the jaw (MRONJ) is a relatively rare but severe adverse reaction to antiresorptive and antiangiogenic drugs. Physicians and dentists caring for patients taking these drugs and requiring invasive procedures face a difficult decision because of the potential risk of MRONJ. The aim of this study was to discuss the risk factors for the development of MRONJ and prevention of this complication in patients with osteoporosis taking antiresorptive drugs and requiring invasive dental treatment. For this goal, a task force with representatives from three professional associations was appointed to review the pertinent literature and discuss systemic and local risk factors, prevention of MRONJ in patients with osteoporosis, and management of established MRONJ. Although scarce evidence links the use of antiresorptive agents in the context of osteoporosis to the development of MRONJ, these agents are considered a risk factor for this complication. Despite the rare reports of MRONJ in patients with osteoporosis, the severity of symptoms and impact of MRONJ in the patients' quality of life make it imperative for health care professionals to consider this complication when planning invasive dental procedures.

ABSTRACT

Leukemic cells are rarely present in the oral cavity, and there are very few reports regarding such cases. However, we identified some reports of leukemic cells infiltrating tissues in the oral cavity, including gingival involvement. Recurrent painful oral ulcerations and prominent generalized periodontal destruction are the most common oral features of neutrophil disorders, and they may even be the initial symptoms of the disease. The ulcers may affect any part of the oral mucosa, including the tongue and palate. The objective of this report is to describe and discuss a case of myeloid sarcoma in the oral cavity of a 48-year-old male patient.

ABSTRACT

Synovial chondromatosis (SC) in the temporomandibular joint (TMJ) is an uncommon entity, mostly when the involvement is bilateral. The authors report a rare case of bilateral SC, with a follow-up of 13 months, and a literature review. A 60-year-old Caucasian woman, with the chief complaint of pain for 6 years in the bilateral pre-auricular region, had a progressive clacking and discomfort on the left side during mouth opening. The panoramic image was suggestive of SC. The bilateral lesion was surgically removed by direct access. Histopathological examination confirmed the clinical diagnosis of bilateral SC. This article shows the importance of a multidisciplinary approach for the early diagnosis and appropriate treatment. Also, it encourages the referral of such cases to professionals with a greater familiarity with this entity.

ABSTRACT

Introdução: O adenoma pleomórfico (AP) ou tumor misto benigno é a neoplasia de glândula salivar mais comum. A glândula parótida geralmente é a mais acometida com 80% dos casos, e, quando surge em glândulas salivares menores, o palato é a região mais afetada. O objetivo deste trabalho é relatar um caso clínico de AP em palato duro, tratado de forma conservadora. Relato de caso: Paciente 35 anos, gênero masculino, apresentando aumento de volume em palato, aos 6 meses de evolução, foi submetido à realização de procedimento cirúrgico, realizado sob anestesia local, para enucleação da lesão, seguido por curetagem de periósteo e com preservação de tecido mucoso sobrejacente. Considerações Finais: No momento, o paciente encontra-se com 1 ano de acompanhamento e não apresenta sinais de recidiva... (AU)

ABSTRACT

Introdução: Os tumores neurais são lesões, que têm origem nos nervos periféricos e representam um percentual de 45% dos neoplasmas, que atingem a região de cabeça e pescoço. A alta incidência nessa área é justificada pela quantidade relativamente grande de terminações nervosas periféricas agrupadas. Ainda que sejam de mesma origem neural, sua heterogeneidade microscópica e patogenética lhes conferem um variado padrão de apresentação clínica e histopatológica, diferindo na sua forma de tratamento. O objetivo do presente estudo foi analisar, por meio da técnica imuno-histoquímica, a expressão das proteínas S100 e CD68 em tumores neurais, localizados na cavidade bucal de pacientes atendidos no Serviço de Patologia Bucal da Universidade de Odontologia de Pernambuco. Metodologia: Todos os casos referentes a tumores neurais do Serviço de Patologia oral e maxilofacial da Faculdade de Odontologia de Pernambuco foram revistos. Avaliaram-se dados relativos à idade, ao sexo e à localização anatômica. A técnica imunohistoquímica foi realizada por meio do método estreptavidina-biotina, utilizando-se os anticorpos anti: S100 e CD68. A análise foi feita de forma descritiva, conforme dados da pesquisa. Resultados: foram avaliados 23 casos de tumores neurais da cavidade bucal, 15 neurofibromas, 6 neuromas traumáticos, 1 neurilemoma e 1 neuroma encapsulado em paliçada. Verificou-se que a proteína S100 foi expressa em todos os casos estudados com positividade variada, e a proteína CD68 apresentou expressão positiva em 18 casos (neuroma traumático, neurofibroma). Conclusões: os tumores neurais da cavidade bucal foram considerados raros, visto que ocorreram em apenas 23 casos entre 5.761, ou seja, em 2,3% das lesões biopsiadas da FOP-UPE... (AU)


Introduction: Neural tumors are lesions that originate from peripheral nerves and represent a percentage of 45% of neoplasms that reach the head and neck region. The high incidence in this area is explained by the relatively large number of grouped peripheral nerve endings. Although they are of the same neural origin, their microscopic and pathogenetic heterogeneity give them a varied pattern of clinical and histopathological presentation, as well as differing in their form of treatment. The aim of the present study was to analyze by immunohistochemical technique the expression of S100 and CD68 proteins in neural tumors located in the oral cavity of patients treated at the Oral Pathology Service of the University of Dentistry of Pernambuco. Methodology: All cases referring to neural tumors of the Service of Oral and Maxillofacial Pathology of the School of Dentistry of Pernambuco were reviewed. Data regarding age, sex, and anatomical location were evaluated. The immunohistochemical technique was performed by the streptavidin-biotin method using the anti-S100 and CD68 antibodies. The analysis was made in a descriptive way according to the research data. Results: 23 cases of neural tumors of the buccal cavity, 15 neurofibromas, 6 traumatic neuromas, 1 neurilemoma and 1 palisade encapsulated neuroma were evaluated. It was verified that S100 protein was expressed in all the cases studied with varied positivity, and the CD68 protein showed positive expression in 18 cases (traumatic neuroma, neurofibroma). Conclusions: Neural tumors of the oral cavity were considered rare, since they occurred in only 23 cases among 5,761, that is, 2.3% of FOP-UPE biopsied lesions... (AU)

ABSTRACT

Introdução: Tendo em vista a importância do campo da patologia oral e maxilofacial, faz-se necessário compreender o impacto da mais recente Classificação dos Tumores de Cabeça e Pescoço da OMS na frequência e distribuição dos cistos e tumores odontogênicos. Este estudo teve como objetivo estabelecer a frequência de lesões odontogênicas ao longo de 12 anos, em um serviço de referência em Patologia Oral, no Nordeste brasileiro. Metodologia: Os casos diagnosticados como cisto (OC) ou tumor (OT) odontogênico de 1999 a 2010 foram revisados e reclassificados de acordo com a atual Classificação da OMS de Tumores de Cabeça e Pescoço. Foram analisados dados referentes ao diagnóstico histopatológico, à localização da lesão, à idade, ao sexo e à etnia. A análise dos dados bivariados foi realizada, calculando-se as razões de prevalência, o teste do qui-quadrado e o teste exato de Fisher. Resultados: Entre 3.034 espécimes, 409 foram OC e 199 foram OT. Os Oc mais frequentes foram o cisto radicular (n = 129) e ceratocisto odontogênico (n = 99). Entre os OT, os mais frequentes foram ameloblastoma (n = 80) e odontoma (n = 47). Conclusões: Houve uma redução considerável na frequência relativa de OT após a reclassificação de lesões... (AU)


Introduction: Due to the importance of oral and maxillofacial pathology, it is necessary to understand the impact of the latest WHO Head and Neck Tumor Classification on the frequency and distribution of odontogenic cysts and tumors. This study aimed to establish the frequency of odontogenic injuries over 12 years in a reference service of Oral Pathology in the Northeast of Brazil. Methodology: All cases which received a diagnosis of odontogenic cyst (OC) or tumour (OT) from 1999 to 2010 were reviewed and reclassified according to the lastest WHO Classification of Head and Neck Tumors. Data regarding the histopathological diagnosis, location of the lesion, age, gender and Ethnicity were analyzed. The bivariate data analysis was performed by calculating the prevalence ratios, as well as the chi-square test and Fisher's exact test. Results: Among 3,034 specimens, 409 were OC and 199 were OT. The most frequent OC were the radicular cyst (n = 129) and odontogenic keratocyst (n = 99). Among the OT, the most frequents were ameloblastoma (n = 80) and odontoma (n = 47). Conclusions: There was a considerable reduction in relative frequency of OTs after the reclassification of important pathological entities... (AU)
