Summary
Mandibular second premolars, though generally are included under bicuspids, are of two types, the 2 cusp and 3 cusp varients. The aim was to determine the prevalence of the two varieties of mandibular second premolars in Kerala population, South India. This descriptive investigation was undertaken in two dental colleges of Kerala, India. A total of 2500 mandibular second premolars were examined for cuspal variations, groove patterns and gender predilection. A slight predilection (52.8%) for 2-cusp variety was noticed. The most frequent occlusal configuration were crescent shaped and Y groove patterns for 2 cusp and 3 cusp varieties of second premolars respectively.
KEY WORDS: mandibular second premolar, cusp forms, groove patterns.
