Abstract
The interface between the restoration and the gingival tissue seems to have a great influence on the final outcome of various treatments. Therefore, the aim of this study was to evaluate the correlation between different morphometric parameters with the thickness of buccal gingiva at the cemento- enamel junction. In 60 periodontally healthy subjects, the six maxillary anterior teeth were examined. Clinical parameters included the gingival thickness, crown width/crown length ratio (CW/ CL), gingival width (GW), papillary height and transparency of the periodontal probe through the gingival sulcus (TRAN). A positive correlation was found between the gingival thickness (GT) and the crown width/ crown length (CW/CL) ratio as well as the papillary height (PH). A weak negative correlation was found between the transparency of probe TRAN and gingival width (GW) with the gingival thickness (GT). Thus, crown form (CW/CL) and papillary height are helpful indicators to determine the gingival thickness at the cemento- enamel junction. The transparency of probe method is subjective and cannot be relied upon for clinical application.
