Introduction: This study was performed to assess the root resorption of retained primary teeth having no successors. Methods: According to the selection criteria, 2232 students were diagnosed and selected. The statistical analysis was performed by using a statistical software IBM SPSS version 21. Results: only 83 subjects had retained deciduous teeth (R.D.T) giving percentage of 3.71%. Periapical radiographs were used to assess the resorption of the roots. Furthermore, 126 roots was found in the (95) R.D.T, (66) roots was in males and (60) was in females and all roots have some form of resorption. No significant relationship was observed between different variables (arch, gender, and sides) and the root resorption, (P value = 0.138, 0.1258 and 0.176) respectively of P <0.05. Conclusion Within the limitation of the study , the primary maxillary canine were the most frequently retained deciduous teeth , followed by the mandibular 2nd primary molar, but the maxillary central incisor and mandibular 1st molar are the least. Regarding levels of root resorption, the level 1 root resorption was the most frequent 51.6 % , followed by level 2, level 3 & level 4 respectively; 23.8 % , 14.3 % & 10.3 %.
