Abstract

Background: There is a strong genetic influence in determination of tooth dimensions bearing an influence on the facial dimension. Aims and Objective: To determine a correlation between clinical crown height of upper and lower permanent incisor (11 and 41), molar (16 and 46) and lower facial height clinically and cephalometrically in males and females. Materials & Methods: A sample of 180 patients were (90 males and 90 females) included in our study,(60-hypodivergent, 60-normodivrgent and 60-hyperdivergent) with an age range of 17-25 years. Threeanthropometric measurements were considered. The lower facial height from subnasale(Sn) to menton, and cephalometric lower facial height distance from anterior nasal spine(ANS) to menton and the clinical crown height of maxillary and mandibular incisors and molars were measured. Observations: Significant difference was observed in relation to 16 in normodivergent patient and lower facial height clinically and cephalometrically in hyperdivergent growth patient. No significant difference between clinical&cephalometric lower facial height in normodivergent, hypodivergent and hyperdivergent male and female patient. Significant difference was observed between 41 to lower facial height in hypodivergent & 11,41 &46 to lower facial height in hyperdivergent patient. Conclusion: A strong significant correlation was observed with clinical crown height of lower central incisor and lower facial height in hyperdivergent and hypodivergent patient.
