Análise do biótipo gengival através de fotografias frontais intra-orais.

Abstract

The correct diagnosis of gum biotypes is extremely important to clinical practices and adequate surgical planning, since success in final treatment depends on the integration of osseous, conjunctive and epithelial tissues. The aim of this study was to assess whether there are inter- and intra-specialties divergences in classifying thin/festonate and plane/thick gum biotypes in frontal inter-oral photographs. In this observational cross-sectional study, fifty photographical images were analyzed by the method of visual inspection by 25 specialists, clinicians in Dentistry, Prosthetics, Periodontics, Implantology and Orthodontics. Variables have been analyzed by the non-parametric Qui-Square statistical test and the assessment of dispersion between levels of non-agreement in answers by the coefficients of variance and mean. The testing established with a level of significance of 5% demonstrated that 74% of the items analyzed accepted the hypothesis and 26% rejected it. The specialties with a level of agreement of 60% were Dentistry (38%) and Orthodontics (38%). Yet in 100% of answer agreement, the largest consistencies occurred in the specialties of Implantology (42%) and Prosthetics (42%). It was possible to conclude that the gum biotype identification through simple visual clinical inspection is not sufficiently reliable for the correct planning of a restorative, surgical, prosthetic, orthodontic and periodontal treatment.
