| ABSTRACT Aim: It is to determine the relationship between gingival thickness and (buccal bone thickness, crown length, crown width, papillary height and papillary width) at upper central incisors teeth by means of a noninvasive and relatively accurate digital registration method. Subjects and Methods: In 100 periodontally healthy subjects, cone-beam computed tomographic images were obtained. Measurements of buccal bone thickness and gingival thickness at the central incisors was performed at points 1 mm from the alveolar crest. Correlation coefficient was calculated to assess the correlation between gingival thickness and buccal bone thickness. Results: The mean and standard deviation values were calculated for each group. Pearson correlation was used to find the correlation between Gingival thickness and each of Bone thickness, Crown length, Crown width, Papillary height and Papillary width. Independent sample t-test was used to compare between females and males’ results in each variable. The significance level was set at p ≤ 0.05A statistically significant difference was found between females and males in all variables Gingival thickness, Bone thickness, Crown length, Crown width, Papillary height and Papillary width where (p<0.001), (p<0.001), (p=0.001), (p=0.027), (p=0.036) and (p<0.001) respectively, where females always showed thin type. There was a significant positive relationship between gingival thickness and Bone thickness, which states that increasing gingival thickness will be accompanied by increasing in bone thickness and vice versa. Conclusion: there are significant correlation between the gingival biotype, bone thickness, Crown length, crown width and papilla of anterior incisor crowns and respectively were females always showed thin biotype than males. | ||||
