Abstract
Aims: To assess the gingival zenith position and its distance from vertical bisecting midline in the maxillary right and left central incisors in Marathwada region.
Materials and methods: 60 participants were selected (34 male and 26 female), considering inclusion and exclusion criteria. 120 teeth were evaluated on diagnostic cast, gingival zenith position (GZP) and vertical bisecting midline (VBM) marked on each tooth. By using magnification loupes and digital vernier calipers, the distance between GZP and VBM was measured three times and average value was recorded. The GZP was recorded as mesial, distal or coinciding with VBM.
Results: Majority of right and left maxillary central incisors shows distal placement of GZP to the VBM and its mean distance from VBM was 0.87 mm. After statistical analysis, it was found that the P value for right and left central incisors was greater than 0.01, which was not statistically significant.
Conclusion: GZP is positioned 0.87mm form VBM and it is important in designing macroesthetics and microesthetics of teeth.
Clinical Significance: These parameters are important during treatment planning of restoration in maxillary central incisors. Deviation from these parameter lead to unappealing and anaesthetic appearance.
