Effect of root resorption of primary teeth on the development of its permanent successors: An evaluation of panoramic radiographs in 7–8 year-old boys

Root resorption in primary teeth can occur as a physiologic or pathologic phenomenon. Physiological root resorption occurs in healthy primary teeth or primary teeth with caries but no pulp involvement, whereas pathological root resorption occurs in primary teeth with pulpal caries. Knowledge about the effects of both physiological and pathological root resorptions in primary teeth on the development of its permanent successors is important for the development of an appropriate proper treatment plan. This study aimed to evaluate the effect of root resorption of primary teeth on the development of its permanent successors in boys aged 7–8 years. This descriptive cross-sectional study comprised 71 primary mandibular molars and premolars, which were screened using 32 sheets panoramic radiographs obtained from 7–8-year-old boys. Root resorption of primary teeth appeared to have no significant effects on the development of its permanent successors in the current study.
