case_images: Representative images of crown-root fracture management of Case 1. Preoperative intra oral view (1A) and periapical radiograph (1B) of lower first and second primary molars, showing crown-root fracture. Stainless steel crowns were placed followed by pulpectomy (1C,1D). Twelve-month (1E), 24-month (1F) and 36-month (1G,1H) follow-up were uneventful

case_images: Intraoral examination revealed a complicated crown-root fracture of the left first and second primary mandibular molars, which was confirmed by a periapical radiograph (Figures 1A and 1B). Ltd, South Korea), restoration with GIC (Fuji II) and composite (3M, ESPE, USA) (Figures 1C and 1D). On the recall visits on months 12 and 24 (Figures 1E and 1F), there was no clinical or radiographic pathology, with physiologic root resorption. The patient was asymptomatic clinically and radio-graphically after 36 months and showed continuation of physiologic root resorption (Figures 1G and 1H).

case_images: Treatment of crown-root fracture in Case 2. Preoperative intraoral photograph (2A) and periapical radiograph (2B) show crown-root fracture in the upper left second primary molar. A stainless steel crown was placed, after which pulpectomy was performed (2C, 2D). No failure was observed in the 12-month (2E), 24-months (2F) and 36-months (2G, 2H) follow-up

case_images: Intraoral examination showed a crown fracture extending from the cervical region to the occlusal surface of the left maxillary second primary molar with subgingival extension of the fracture line (Figures 2A and 2B). Because of the patient's age, conservative treatment was opted similar to that discussed in Case 1, i.e., stabilization with stainless steel crown followed by endodontic therapy of the offending tooth (Figures 2C and 2D). The child was followed for 12, 24 (Figures 2E and 2F) and 36 months with no clinical/radiographic signs of failure (Figures 2G and 2H).
