Lesões bucais em pacientes pediátricos : estudo retrospectivo de 620 biópsias registradas no Laboratório de Patologia Bucal da Universidade Federal de Uberlândia-MG-Brasil

At childhood, specifically, dentistry has been restricted to dentition and periodontal tissues maintenance, which is basically evidenced by caries, periodontal illness and malocclusion prevention and treatment. This approach leaves lacunae as to diagnosis and treatment of soft and hard tissues lesions. Studies aiming this knowledge are sparse, restricted to that epidemiological ones of population database or isolated clinical cases reports. The aim of this study was to perform an epidemiological retrospective study of oral illness at pediatric age, based on diagnosed cases searched from Uberlândia s Federal University Oral Pathology Laboratory between 1978 and 2004 periods. For this study 7292 recorded cases were obtained in this period (27 years) from Laboratory records. From the total, 8.5% of the cases, corresponding to 620 biopsies, matched limit age criteria (0-14 years old) and were located on oral tissues. For its ranking, a modified Happonen et al. (1982) criteria, grouping lesions in 10 categories. Our results evidenced that major of cases were located in the older group between 10-14 years (375/620), females were more affected (356/620) and lower lip was the most frequent location (198/620). Ten recognized categories from samples presented the following frequency: hyperplasic and soft tissue reaction lesions (20.2%); soft tissue benign tumors (7.0%); oral mucosa lesions (3.4%); maxillary and oral soft tissue cysts (14.4%); periapical and fibrous scar illness (4.2%); odontogenic tumors (6.1%); bone lesions (2.7%); salivary glands lesions (35.5%); malign lesions (0.9%) and normal tissue and dental specimens (5.5%). Major number of lesions was found on salivary glands lesions group (35.5%), hyperplasic and soft tissue reaction lesions (20.2%) and maxillary and soft tissues cysts (14.4%). Mucocele was the most prevalent entity (33.7%) in all study followed by dentygerous cyst (6.8%) and fibrous hyperplasia (5.3%). Twelve most frequent lesions were responsible for 74% of the whole sample. ; Mestre em ...
