Description
INTRODUCTION: The dentogingival unit is the anatomical complex formed by the gingiva, gingival sulcus, junctional epithelium and connective tissue insertion, also known as “biological space”. The biological space is essential for the success of various procedures in Dentistry and consequent maintenance of periodontal health. OBJECTIVE: Characterize the gingival phenotype and determine the dimensions of the dentogingival unit in the anterior region of the maxilla with CBCT analysis. MATERIALS AND METHODS: The total population of the study consists of 50 individuals. A CBCT of the anterior maxilla of each participant was performed with the MID Planmeca ProMax® 3D equipment with the same specifications / conditions. The characterization of the dentogingival unit was performed by measuring the following parameters on teeth 21 and 11: Free Gingival Thickness; Thickness of Adhered Gingiva; Gingiva Thickness in Supracrestal Insertion; Thickness Alveolar Bone; Distance from the Alveolar Crest to the Amelocement Line; Distance from the Amelocement Line to the Free Gingival Margin; Alveolar Height; Alveolar Width; and Mesio-distal diameter of the foramen incisor. RESULTS: The mean values in each parameter for the teeth 11 and 21 were obtained, as well as the Pearson correlation values between variables, and those that presented statistical relationship were ‘free gingival thickness’ and ‘thickness at supracrestal insertion’; alveolar width and height; and between ‘distance from amelocentral line to alveolar crest’ and ‘distance from amelocentral line to free gingiva’. Regarding the analysis by gender, there was a statistically significant positive association between males and measurements of ‘alveolar width’ and ‘incisive papilla’ parameters. A statistically significant negative relationship was found between the existence of ‘prior orthodontic treatment’ and ‘alveolar bone thickness’, found in both teeth studied. CONCLUSIONS:Within its limitations, this study proved the reliability and effectiveness of CBCT as a method of analysis of these variables, and it was possible to successfully determine several parameters of the dental gingival unit using the CBCT.| Period | 27 Jul 2019 |
