  Background and Aim: Periodontium biotype has many variations among different people. It has been suggested that the variation in the periodontium biotype may be related to the shape and form of the crowns of the teeth. The aim of this investigation was to examine the forms of the crowns in the maxillary anterior segment and corresponding gingival characteristics among healthy young Iranian subjects.


  Materials and Methods: For this cross-sectional study 200 individual (100 male & 100 female) with average age of 26.5 ± 7.29 with healthy periodontium were chosen from dental students of Islamic Azad University. The gingival angle, height of interdental papilla, crown width and crown height of maxillary anterior teeth were measured by a digital caliper on a diagnostic stone cast. Also marginal gingiva’s thickness, probing depth and width of keratinized gingival was assessed clinically by a William’s probe on each individual. Binary logistic regression method was used for statistical analysis. 

  Results: In central teeth (11-21) gingival thickness had a significant correlation with amount of keratinized gingiva and probing depth. In lateral teeth (12-22) gingival thickness had significant correlation with amount of keratinized gingiva, probing depth and crown width. In canine teeth (13-23) gingival thickness had significant correlation with amount of keratinized gingiva, probing depth, crown’s height, papilla’s height and gingival angle. There was no statistical relation between crown’s form and gingival thickness.


  Conclusion: Based on the findings, crown form had no relation with the gingival thickness but in each type of tooth gingival thickness was related to different factors.
