Abstract

Background:  Gingival zenith is the most apical point on the marginal gingival scallop and an important landmark described as having a specific spatial orientation in the apico-coronal and mesio-distal direction. Gingival health is among the first fundamental aesthetics objectives during treatment planning. The knowledge regarding the quantitative value of the gingival zenith position of maxillary anterior teeth which is the most esthetic zone will be beneficial during treatment procedures like crown lengthening, restoration, prosthetic replacement and also during orthodontic treatments. Materials and methods: A total of 360 sites in 30 healthy subjects were evaluated. Bilateral gingival zenith measurements were carried on the maxillary impression stone cast. Canine, lateral incisor and central incisor were evaluated for the mesio-distal displacement of gingival zenith in relation to the long axis of crowns. Apicocoronal displacement of the gingival zenith of the lateral incisor concerning the central incisor and canine teeth was also recorded. Statistical analysis: Commercially available statistical software (SPSS version 11.5) was used to analyze the data. Result: Distal displacement of gingival zenith was between 0.26 to 1.01 mm in 90%, 85% and 60% of the central incisors, lateral incisors, and canines, respectively. The gingival zenith's mesial position in relation to the long axis of the crown was not observed in any tooth, regardless of the tooth group. Conclusion: The frequency and magnitude of distal displacement are tooth-dependent and larger in central than in lateral incisors, which in turn, is larger than in canines.
