AVALIAÇÃO TOMOGRÁFICA DAS DIMENSÕES VERTICAIS DOS TECIDOS PERIODONTAIS SUPRACRESTAIS EM DENTES ANTERIORES DA MAXILA.

The aim of this study was to evaluate the dimensions of the supracrestal periodontal tissues (SPT) on tomographic scans. One hundred patients, 600 maxillary anterior teeth (200 central incisors, 200 lateral incisors and 200 canines), were evaluated. The average distance from the gingival margin to the alveolar bone crest (ABC) was 3.25mm (95% CI: 3.20-3.30), while the distance from the cemento-enamel junction to ABC was 1.77mm (95% CI: 1.72-182mm). The measurements were significantly different between the tooth groups (ANOVA, p < 0.001). When properly indicated, tomography can be an important tool for assessing the dimensions of TPSCs on a case-by-case basis. Keywords: biologic width, supracrestal attached tissues, periodontal supracrestal soft tissues, cone beam computed tomography.
