ABSTRACT

Introduction: The term gingival biotype is used to describe the gingiva's thickness in facio-lingual dimension. Gingival thickness determined by size and shape of root and contour of alveolar bone. Thick gingival biotype is characterized by dense tissue more than 2 mm and thin gingival biotype is translucent less than1.5 mm. It is considered an important factor in periodontal and orthodontic therapy success. During orthodontic tooth movement, if the mandibular teeth are moved in labial direction, it may lead to resorbtion of labial cortical plate and eventually gingival recession.
Objective: To assess the gingival biotype and phenotype in mandibular central incisor before and after orthodontics treatment.
Material and Methods: This study evaluated gingival thickness on mandibular central incisor on 10 orthodontic patients before and after treatment using two different methods:1) transgingival probing method and 2) visual method.
Result: It was observed that no statistically significant difference in the transgingival probing method from the visual method.
Conclusion: Gingival phenotype changes before and after orthodontic treatment.
