Background: Primary teeth undergo physiological root resorption followed by eruption of their permanent successors. Roots of primary mandibular molars can have either symmetrical or asymmetrical resorption patterns. This study aimed to determine the frequency of root resorption patterns of primary mandibular molars and the position of premolar successors through radiographs in children. Methods: A total sample of 240 primary mandibular teeth from 140 patients (5-12 years) who visited the Paediatric Dentistry Department of Fatima Jinnah dental college were reviewed using radiographs. The root resorption patterns of primary mandibular molars and the location of the premolar successors were determined. Effect modifiers were controlled through stratification concerning age, gender, right or left side and presence of caries. Post-stratification chi-square analysis was used and p
