Abstract

Background: Gingival biotype can be influenced by genetic factors, tooth-related factors and biological issues. This study aimed to determine the biotype of facial gingival and related factors.

Methods: In this study, 300 patients (128 males and 172 females) with a mean age of 36.2 ± 13.27 were selected by simple random sampling. Patients’ characteristics including age, gender, smoking, dental and keratinized gingival anatomy and oral hygiene parameters were recorded and their associations with gingival biotype were investigated using Transparency method. Collected data were analyzed by SPSS24 using t test, Mann-Whitney, ANOVA, and Pearson correlation coefficient. The P<0.05 was considered significant.

Results: Frequency of thin gingival biotype was higher than that of thick gingival biotype. There was a significant relationship between gingival biotype of upper central incisors areas and age (P < 0.001), vibratory brushing (P=0.019) and keratinized gingival width (P=0.021). There was also a significant relationship between the gingival biotype of lower central incisor area and gender (P=0.036), vibratory brushing (P=0.010), vertical brushing (P=0.009) and keratinized gingival width (P=0.011). Moreover, a significant direct relationship was discovered between Gingival biotype of upper and lower central incisors areas. No relationship was found between frequency and duration of brushing, dental flossing, plaque index, tooth shape, and smoking with gingival biotype (P> 0.005).

Conclusions: Gingival biotype was associated with age, gender and keratinized gingival width, as well as some brushing characteristics such as the brushing method.
