Aim or purpose: The present study aimed to evaluate the mean gingival thickness of mandibular anterior region in individuals with norm values of lower incisor position.
Materials and methods: 83 periodontally healthy individuals, with norm values of lower incisor position were enrolled in this study. The gingival thickness of mandibular anterior teeth was deter- mined by the arithmetical mean of gingival thicknesses measured by transgingival probing technique from the coronal mucogingival junction and apical of free gingival sulcus. The mean gingival thickness of mandibular anterior region was determined by the ratio of the sum of gingival thickness of the relevant teeth to the number of teeth.
Results: The gingival thickness of mandibular central, lateral and canine teeth was 0.709 " 0.180 mm, 0.805 " 0.211 mm and 0.665 " 0.192 mm respectively. The mean gingival thickness of mandibular anterior region was 0.692 " 0.163 mm in females and 0.773 " 0.137 mm in males. It was observed that the differ- ence between mean gingival thickness of females and males was statistically significant (p = 0.021). The mean gingival thickness of mandibular anterior region was 0.723 " 0.158 mm in both sexes. It was observed that the incidence of thin gingival biotype was % 95.2 in the mandibular anterior region.
Conclusions: It was determined that the mean gingival thickness of mandibular anterior region was less than 1 mm. In order not to face periodontal pathologic problems such as gingival recession in these individuals, tooth movements must be done within the ana- tomic limits of alveolar bone during the orthodontic treatment.
