Root Morphology and Tooth Length of Maxillary First Premolar in Nepalese Population

Kafle Dashrath*,Acharya Nisha,Sthapit Subodh

Introduction: Maxillary first premolar teeth are commonly extracted teeth for orthodontic purpose and commonly root treated tooth because of dental caries. There are different variations on root form, number as well length of the root and tooth.
Objective: To find out the root morphology and average tooth and root length of maxillary first premolars in Nepalese population samples.
Materials and methods: Total 100 maxillary first premolar teeth were collected for the study and carefully stored in chambers separated for male and female. Root form was identified and recorded. Similarly tooth length and root length was measured by digital caliper (MC, China) and compared by independent t-test. Result: 58% of the samples had single rooted roots. Whereas double root, fused root and triple root form were 20%, 21% and 1% respectively. There was not any significant difference on male and female toot and root length.
Conclusion: Majority of Nepalese premolars have a tendency to be single rooted. Overall tooth length is shorter than the established tooth length.
