Abstract

Introduction: Various factors determine the morphological characteristics of gingiva, which plays an important role in the final aesthetic outcome. Gingival biotype is described as a buccolingual dimensions of the gingiva.

Objective: The aim of the study was to find the correlation between gingival biotypes and tooth forms.

Methods: This analytical cross-sectional study was done in 360 patients visiting Department of Dental Surgery, Bir Hospital. The data collection was done from 2020 February to 2021 January using convenience sampling technique. All the parameters were assessed and recorded. The crown width/crown length ratio determined the tooth form. The gingival biotype was classified as thin and thick and was measured by the method of transparency of periodontal probe. Data were analysed using SPSS software v.26.

Results: The result showed that thick gingival biotype was seen in 254 (70.6%) and 106 (29.4%) participants had thin gingival biotype. Square tooth form was most common (256, 71.1%), followed by ovoid (68, 18.9%), and tapered tooth form (36, 10.0%). Thick gingival biotype was seen more than thin gingival biotype among total square, ovoid, and tapered tooth form compared to thin gingival biotype which was not statistically significant (p-value = 0.060).

Conclusions: Within the limitation of the study, it was concluded that there was no correlation between gingival biotype and tooth form.
