Anais da Academia Brasileira de Ciências
The present study aimed to perform an epidemiological survey on the prevalence rate of oral lesions diagnosed in a referral center in Brazil and to establish association between the lesions and the age and gender of the affected patients. This analytical observational study analyzed 3521 medical records of anatomopathological exams of the Pathological Anatomy and Cytopathology Laboratory of the Cancer Hospital of the state of Mato Grosso (Brazil), from December 2011 to September 2015. A total of 1550 relevant medical records was detected. Patients aging between 41 and 60 consisted of 42.84% of the sample. Males were more affected than females (60.13%). Inflammatory processess consisted of the most prevalent diagnosis (43.29%), followed by squamous cell carcinoma (6.06%), and periapical granuloma (5.23%). Oral health public policies must give major attention to Brazilian males aged between the fourth and sixth decades of life in order to improve their quality of life.

To determine the frequency and spectrum of oral and maxillofacial lesions biopsied in a hospital population in the northern region of Portugal. We conducted descriptive analyses of pathology reports from biopsies of oral and maxillofacial lesions performed between 1990 and 2006, in Oporto Hospital Center. Information on gender and age of patient, location of the lesions and the histopathological diagnosis were analysed. The analyses revealed that 1,520 (47.7%) patients were male and 1,666 (52.3%) were female. They had a mean age ± standard deviation of 47.8 ± 18.6 years. The site most frequently biopsied was the labial mucosa (17.5%). A non-neoplastic diagnosis was established in 2,162 (63.3%) cases, potentially malignant disorders in 163 (5.1%) and neoplasms in 886 (27.6%) (403 benign and 483 malignant). The most commonly reported diagnosis was fibroepithelial polyp (n = 186; 15.9%), followed by squamous cell carcinoma (SCC) (n = 158; 13.6%). SCC was the lesion most commonly found ...
Oral Lesions Diagnosed during Oral Cancer Prevention Campaign in Fernandópolis, Brazil, 2015
World Journal of Dentistry, 2015
Background To describe oral lesions diagnosed during oral cancer prevention campaign performed in Fernandópolis, Brazil, in 2015. Materials and methods Patients who attended for the Basic Health Units of the city of Fernandópolis on the day of the campaign were examined by dental surgeons who searched for oral lesions clinically suggestive for oral squamous cell carcinoma (SCC) or potentially malignant lesions. Final diagnosis was obtained by a re-evaluation of patients with suspicious lesions performed by an expert in oral diseases. Results Seven hundred and sixty-two patients were examined during the campaign; although 96 (12.59%) presented with oral suspicious lesions and forwarded for re-evaluation, only 72 (9.44%) attended for re-evaluation and got the final diagnosis. Among re-evaluated patients, only 1 (1.38%) was diagnosed with oral SCC, whereas 56 (77.77%) were diagnosed with oral benign lesions, and 19 (26.38%) were diagnosed with oral normality variations. Conclusion Oral...
Oral soft tissue biopsies in Oporto, Portugal: An eight year retrospective analysis
Journal of Clinical and Experimental Dentistry, 2015
Background: The diseases that affect the oral cavity are wide and diverse, comprising a broad spectrum of either benign or malignant lesions. However, few histological-based studies were performed for the evaluation of oral cavity lesions, and very few directed to oral soft tissue pathology. The aim of this study was to carry out pioneering research, within a Portuguese population, to determine the frequency and characteristics of oral malignancies, potential malignant disorders, and soft benign tissues pathologies submitted for biopsy in a north Portugal (Oporto) hospital population. Material and Methods: We performed a retrospective study of soft tissue, oral cavity biopsies, in a hospital north of Portugal (Oporto) between 1999 and 2006. We analysed information on gender, age, location of the lesion, and the histopathological diagnosis. Results: A total of 1042 oral biopsies were observed, 557(53.5%) in females and 485 (46.5%) in males, with a mean age of 51.7 years (S.D. ±17.6). The topographic location most frequently affected was labial mucosa (n=306). Considering the nature of the lesions, 700 (67.2%) corresponded to non-neoplasic lesions, 45 (4.3%) to potentially malignant disorders, and 297 (28.5%) to neoplasms (93 benign and 204 malignant). Non-neoplasic lesions were more prevalent in female gender (59.9%) when compared with potentially malignant disorders (46.7%) and neoplasms (39.4%) (P< 0.001). Non-neoplasic lesions presented the lower mean age (49.2±17.6) and potentially malignant disorders the highest mean age (60.5±14.5) (P< 0.001). The most common lesion of entire sample was fibro-epithelial hyperplasia (n=186; 17.9%), followed by squamous cell carcinoma (n=158; 15.1%).

Introduction: As one of the most common human malignancies, oral and oropharyngeal cancer represents a challenge in global public health. Objective: To describe the lesions diagnosed during an oral cancer prevention campaign carried out in Fernandópolis, Brazil, in 2018. Material and methods: Patients treated at the basic health units in Fernandópolis on the day of the campaign were examined by a previously trained dentist who looked for suggestive oral lesions with malignant potential. Patients with suspicious lesions were scheduled for re-evaluation by an oral disease specialist to obtain the correct diagnosis of the lesion. Results: 956 patients were examined during the campaign. Among them, 75 (7.84%) were referred, however, 66 (88%) attended for reassessment and proper diagnostic management by the dentist specializing in oral diseases. Were diagnosed 59 benign oral lesions and 23 variations from normality, no patient was diagnosed with malignant oral lesion. Conclusion: The absence of a diagnosis of oral cancer during the campaign suggests the need to reassess its methodology, aiming to reach a target audience with a higher risk of carrying oral lesions that lead to malignant manifestations. It is also noteworthy that health professionals need better training to clinically recognize lesions suggestive of oral cancer.

Aim To perform an epidemiological and clinical analysis of cases of oral cancer (OC) and potentially malignant disorders (PMDs). Subjects and methods This retrospective study was based on the analysis of data from 631 patients who attended a clinic of the Interdisciplinary League of Oral Cancer (LINCCO) of a public university of northeastern Brazil over a time period of 12 years. Sociodemographic, economic, and clinical variables were investigated. Descriptive, bivariate, and multivariate statistical analyses using Poisson regression were performed. Results During the analyzed period, 19.3% (n = 122) of cases were related to diagnoses of some type of OC or PMDs. The majority of patients were male (60.7%) and in the fifth (22.0%) or sixth (23.7%) decades of life. The reported smoking and alcohol consumption were 27.0% and 27.9%, respectively. The most prevalent lesions were actinic cheilitis (48.4%) and squamous cell carcinoma (SCC) (23.8%). The most affected anatomical region was the lower lip (45.1%). The prevalence of smoking was higher among those who presented with OC [prevalence ratio (PR) = 2.56, 95% confidence interval (CI) = 1.54-4.24, p < 0.001)] compared to those who presented with a PMD. Conclusion Public health managers and the scientific community should continue to direct efforts to raise public awareness about protective and preventive measures for OC and PMDs, including early diagnosis and frequent visits to the dentist. Otherwise, the rates of these injuries may continue to grow exponentially, significantly impacting the health indicators of the population.

Gerodontology 2010;00; doi: 10.1111/j.1741-2358.2010.00370.x Epidemiological study of 534 biopsies of oral mucosal lesions in elderly Brazilian patientsBackground: The number of elderly people in Brazil has increased during the last few decades. Oral lesions are very common in this age group, but few studies have examined the prevalence of these conditions worldwide and, particularly, in Brazil.Purpose: This study aimed to evaluate the frequency of oral lesions in an elderly Brazilian population.Materials and methods: A total of 534 cases of oral lesions retrieved from the files of the Oral Pathology Laboratory of the School of Dentistry, University of Pernambuco, between 1991 and 2008, were descriptively and qualitatively evaluated.Results: In this study, the oral mucosal lesions cases preferentially affected women (n = 357; 66.8%), white persons (n = 253; 47.3%), in the seventh decade of life (n = 361; 67.6%), and with lesions predominantly located on the gingival/alveolar ridge (n = 102; 19.1%). The non-neoplastic lesions (n = 353; 66.1%) were more prevalent than benign neoplasms (n = 85; 15.9%), oral cancers (n = 56; 10.4%) and potentially malignant lesions (n = 40; 7.4%). The five most predominant diseases were fibrous hyperplasia, non-specific chronic inflammatory processes, oral squamous cell carcinoma, non-specified odontogenic cysts and epithelial dysplasia.Conclusions: Our results may be helpful in understanding the distribution of oral diseases in this very specific age group that requires special attention.

The aim of this study was to perform a retrospective study of 1,894 maxillofacial injuries diagnosed in a public laboratory in Mato Grosso and verify the association by considering the following variables: gender, age, anatomical locationand origin of the patient (capital, interior). Methods A sample was selected in the period from2005 to 2008 in order to assess the prevalence of oral lesions in a Public Laboratory (MT Laboratório). Results Chronic gingivitis was the most prevalent lesion, with a frequency of 11.46%, followed by inflammatory fibrous hyperplasia (7.44%), mucocele (7.23%) and fibroma (5.54%). Females were affected in50.63% of cases and males49.37%. However, there is no difference in gender (p=0.435). The second decade of lifeshowed a higher prevalence of injuries. The region of the jaw proved to be the most affected (24.45%) and most patients came from the interior. There was a statistically significant association between some pathologies and sex(p<0.001) among the most prevalent anatomical locations and gender (p<0.001) and origin of the patient (p<0.001). Conclusion It can be concluded that chronic gingivitis was the most prevalent lesion. There was a statistically significant association between some pathologies and sex, amongst the most prevalent anatomical locations and sex and origin of the patient.
