Introduction: Not many investigations have evaluated the relationship between the height of the interdental papillae, gingival zenith and maxillary anterior teeth. The assessment of these parameters can aid in fabricating definitive aesthetic restoration.
Aim: The aim of this study was to evaluate the existence of proportional ratio between the incisal edge to gingival zenith (HGZ) and the tip of the interdental papilla (HIP) in maxillary anterior teeth for Indian population.
Materials and Methods: One hundred healthy volunteers with an average age of 25-30 years comprised the evaluation group. Impression was made using irreversible hydrocolloid impression material and type IV Dental stone cast was made. A calibrated digital caliper measured the distance between HGZ and HIP. The values for all six maxillary teeth were recorded and the proportional ratio was evaluated and statistically analysed.
Results: The mean ratio between HGZ and HIP of all maxillary anteriors in 1st and 2nd quadrant was 1.80, 1.71, and 2.03 in central incisor, lateral incisor and canine respectively with p-value > 0.9.
Conclusion: The mean proportional measurements for maxillary anterior teeth were determined and no definitive proportion existed between HGZ and HIP of maxillary anterior teeth.
