Lip squamous cell carcinoma in a Brazilian population : epidemiological study and clinicopathological associations
2010
Objectives: It was evaluated epidemiological aspects of primary lip squamous cell carcinoma (LSCC) and its associations with clinicopathological factors. Study design: This retrospective, cross-sectional study analysed a sociodemographic, clinical, and morphological data of HNSCC in a Brazilian population (n=30). Data analysis included descriptive statistics and bivariate analyses using the chi-square and Fisher's exact tests to compare the variables. Results: The LSCC represented 10.8% of all oral cavity squamous cell carcinoma. Lip malignant disease was more prevalent in elderly men, with male-to-female ratio of 5:1. Lower lip was more affected. It was observed high rates of chronic solar…
The relative frequency of odontogenic tumors : a study of 376 cases in a Brazilian population
2017
Background Odontogenic tumors (OTs) are rare lesions, exclusive of the jaws, that are derived from epithelial and/or ectomesenchymal elements of the tooth-forming apparatus. Their biological behavior is heterogeneous, including hamartomatous tissue proliferation, benign nonaggressive and aggressive neoplasms, and malignant tumors with metastatic capacity. The aim of this study was to describe the relative frequency of odontogenic tumors in a Brazilian population. In addition, a review of the literature identified studies on odontogenic tumors that follow the 2005 World Health Organization. Material and Methods A total of 376 cases of odontogenic tumors from an oral pathology service were re…
Odontogenic cysts: Demographic profile in a Brazilian population over a 38-year period
2009
Objective: To determine the distribution of odontogenic cysts diagnosed histologically over a period of 38 years in a Brazilian population according to age, gender and site affected and to compare these data with previously reported studies from other countries. Study design: A total of 1019 cases of odontogenic cysts diagnosed between 1970 and 2007 were studied. Clinical features obtained from the patient records and microscope slides were reviewed according to the 1992 World Health Organization classification. Results: The mean age was 31.0 years, and there was a predominance of females. The most frequent odontogenic cysts were radicular cysts (61.4%), followed by dentigerous cysts (20.1%…
Retrospective study of 289 odontogenic tumors in a Brazilian population
2016
Background: Odontogenic tumors (OTs) are considered important among oral lesions because of their clinicopathological heterogeneity, and variable biological behavior. This paper aims to determine the frequency and distribution of OTs, over a period of 10 years, at a public university in Northeastern Brazil and compare this data with previous reports. Material and Methods: We reviewed all cases of OTs from oral pathology laboratory of University of Pernambuco (UPE), from 2004 to 2014. Diagnoses were re-evaluated and the tumors were classified according to the latest (2005) World Health Organization Classification of Tumors. In addition, we searched in the English-language literature retrospe…
Demographic profile of oral nonodontogenic cysts in a Brazilian population
2013
Objectives: The purpose of this study was to determine the clinical and demographic characteristics of oral non- odontogenic cysts (ONOC) in a Brazilian population over a 53-year period and to compare this data with the literature. Study D esign: A total of 20.391 biopsies records were evaluated, from April/1959 to August/2012. Cases of oral developmental cysts were selected. Data regarding age, gender, time of evolution, and anatomic site of all cases were collected. The data were analyzed by descriptive statistics. Results: Among 20.391 oral biopsies, 71 (0.35%) met the criteria of ONOC. Females accounted for 50.70% of all cases. The mean age observed was 38.14 years (range: 5-88 years). …
Oral lipomas in a Brazilian population : a 10-year study and analysis of 450 cases reported in the literature
2009
Objectives: Lipomas are common benign mesenchymal neoplasms that rarely occur in the oral cavity and correspond to less than 4.4% of all benign oral soft tissue tumors. This study describes the clinical, radiological and histological features of cases of oral lipomas seen over a period of 10 years and compared the findings with those reported in the literature. Study Design: All cases of oral lipomas seen between 1999 and 2009 were retrieved from the archives of the Stomatology Division of the Federal University of Ceará, Brazil. Age, gender, tumor location, clinical findings, duration, histological subtypes, and treatment outcome were recorded. In addition, the English-language literature …
Prevalence of carotid artery calcifications among 2,500 digital panoramic radiographs of an adult Brazilian population
2018
Background The aim of the present study was to analyze the epidemiological data of digital panoramic radiographs revealing suggestive images of carotid artery calcifications (CAC) from a Northeast Brazilian population. Material and Methods A cross-sectional retrospective study was conducted with 2,500 digital panoramic radiographs obtained from a single imaging reference center in Northeast Brazil. Images from individuals of both sexes and older than 18 years were included and those that did not cover the region of cervical vertebrae or presented low radiographic quality were excluded. Data were analyzed regarding prevalence, location (bilateral, right or left), sex, and age using the Chi-s…
Nonendodontic periapical lesions: a retrospective descriptive study in a Brazilian population
2021
Background Several nonendodontic diseases can occur in the periapical region, resembling endodontic inflammatory conditions. Therefore, the aim of the present study was to determine the frequency of nonendodontic periapical lesions diagnosed in a Brazilian population. Material and Methods The files of two Oral Pathology laboratories were reviewed and all cases including at least one clinical diagnosis of endodontic periapical lesions were selected for the study. After initial selection, demographic and clinical data, clinical diagnosis and final diagnosis were reviewed and tabulated. Final diagnosis included endodontic periapical lesions, and benign and malignant nonendodontic periapical le…
Epidemiologic study of odontogenic and non-odontogenic cysts in children and adolescents of a Brazilian population
2017
Background The objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. Material and Methods Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. Results A total of 2.114 biopsy records of pediatric patients were analyzed with oral and maxillofacial lesions. Data such as gender, age, anatomical location, and histopathological diagnosis were collected and categorized. Among all oral and maxillofacial lesions (n=2.114), were diagnosed 294 cases of odontogenic cys…
Analysis of familial incidence of non-syndromic cleft lip and palate in a Brazilian population
2009
Background: The purpose of this study is to follow the familial incidence of non-syndromic or isolated cleft lip, with or without cleft palate (NSCL/P), and to analyze the relationships between the type of NSCL/P in the affected individual and his/her parent, looking at children in the first grade.

Detailed histories were collected regarding the familial incidence of NSCL/P. For the 185 individuals, the relationship between the type of NSCL/P and the sociodemographic and personal characteristics of the affected person and her/his cleft relatives was …
