Abstract

Objectives: To describe radiographic characteristics of primary molars indicated for pulpectomy at the High - Tech Center - School of Dentistry, Hanoi Medical University. Subjects and Methods: A cross-sectional descriptive study was conducted on 64 primary molars from children aged 4–8 years requiring pulpectomy. Radiographic features including carious lesion site and size, root resorption, periradicular bone loss, root development stage, and diagnosis were recorded. Data were analyzed using Fisher’s exact test with a significance level of p < 0.05. Results: The second primary molars in the mandible accounted for the highest proportion of pulpectomy cases (48.4%). Very large carious lesions were observed in 57.8% of cases, mainly on occlusal surfaces or both occlusal and proximal. Pathological root resorption was present in 43.8% of cases and was significantly associated with extensive bone loss and pulp necrosis. Conclusion: Radiographic features such as root resorption, periradicular bone loss, and large carious lesions are closely associated with the severity of pulpal damage. Radiographs play a crucial role in early diagnosis and treatment for primary molars.
