SIP, size of the incisive papilla; CAIP, distance between the labial surfaces of the central incisors and the anterior border of the incisive papilla; CPIP, distance between the labial surfaces of the central incisors and the posterior border of the incisive papilla. Significant difference between males and females. Males and females were compared using Student’s t-test.
