Abstract
Objective: The purpose of this in vitro study was to investigate variations in the root canal morphology of
mesiobuccal root of maxillary first permanent molars in local population of Rawalpindi and Islamabad.
Study Design: Descriptive cross sectional study.
st
Place and Duration of Study: The study was conducted from 1 January to 30th June 2017 at Islamic
International Dental Hospital (IIDH), Riphah International University, Pakistan.
Materials and Methods: Mesiobuccal root of eighty two maxillary first permanent molar teeth collected from
Islamabad and Rawalpindi were analyzed using the Clearing Technique. Convenience sampling technique was
used. Data was analyzed by using SPSS version 24. Descriptive statistics were used. Frequency and percentages
were calculated for types of canal configuration.
Results: The frequency of a single canal orifices in the mesiobuccal root of maxillary first molar was 48.7% (type I,
III, V and others), that with two canal orifices was 50% (type II, IV, VI and others), whereas with three canal
orifices was 1.23% .
Conclusion: According to the results of this study, a second canal is common occurrence in local population of
Rawalpindi and Islamabad. The distribution of canal configurations of our population differs from other
populations suggesting ethnic/racial divergence.
