Aim: The purpose of this study was to investigate the root canal morphology of the primary maxillary right first and second molars using CBCT according to Vertucci & New root canal classification system given by Ahmed HMA et al., Method: 60 Patients aged 3-9 years were taken in the study. The CBCT of maxillary right quadrants of study subjects were taken at imaging centre and evaluated on CBCT scans according to Vertucci & Ahmed HMA et al.,’s classification both. Result: The most common canal configuration for right primary maxillary 1st and 2nd molar was Vertucci Type I except mesio-buccal canal in right maxillary second molar was Vertucci Type IV. Conclusion: As deciduous molar teeth exhibit thin torturous canals and ribbon like roots a thorough knowledge of the root canals can improve the outcome of pulp treatment in pediatric patients.
