RESUMO:

INTRODUCTION: The identification of the periodontal biotype is an important tool in the diagnosis and prognosis of periodontal treatments. In the treatment of gingival recession, the palatal region has been described as the main graft donor area. PURPOSE: This study aimed to investigate the difference in thickness of the palatal mucosa in individuals with thin and thick biotypes, evaluated in different regions. METHODS: This study included 30 periodontally healthy patients submitted to computed tomography (CT) scans. The images were acquired on the CS8100 3D tomograph and all parameters were analyzed tomographically in the CS 3D Imaging software. The gingival thickness was measured in the maxillary central incisors and categorized into thin or thick biotype. Then, the thickness of the palatal mucosa was measured in the canine, 1st premolar, 2nd premolar and 1st molar at 3mm, 6mm, 9mm and 12mm from the gingival margin. The Mann-Whitney, Wilcoxon and Friedman tests were used to evaluate differences in palatal mucosa thickness between groups, between teeth and in different regions, respectively. RESULTS: There was no statistical difference in mucosal thickness between the groups and between the different teeth analyzed (p> 0.05). In all analyzed teeth, the furthest from the gingival margin, the thickness of the palatal mucosa was higher (p <0.0001). CONCLUSION: In the analyzed sample, the palatal mucosa thickness was not correlated to the type of patient biotype and there was no statistical difference between the different teeth evaluated. However, it was observed that, independently of the tooth, areas more distant from the gingival margin may be better suited to grafting procedures because they have a higher tissue thickness.
