- Abstract
Objective: To determine the root morphology, tooth and root length of maxillary first premolars in Indian and Filipino population. Materials and Methods: A total of 121 maxillary first premolars that were extracted for routine orthodontic procedure were examined in this study. The root forms were identified as one root, two roots, three roots and fused roots. The root length is measured from middle of cemento-enamel junction of buccal aspect and the tooth length is measured from tip of buccal cusp to the root apex using a digital vernier caliper. Root length and tooth length comparisons between gender and two races were done by independent t-test. Results: In our study, 49.22% and 60.7% of the Indian and Filipino samples are found to have single root respectively. In the present study the mean tooth length was 21.97 mm in Indian samples and 21.45 mm in Filipino sample. The mean root lengths were 13.46 mm and 13.39 mm in Indian and Filipino sample respectively. No significant correlation among age and gender was noted. Conclusion: Most the maxillary first premolars in Indian and Filipino were single rooted. The mean tooth length was 21.97 mm in Indian samples and 21.45 mm in Filipino sample and the mean root lengths were 13.46 mm and 13.39 mm in Indian and Filipino sample respectively.
