Short summary
A 13-year-old boy presented with molar root-incisor malformation (MRIM), a rare developmental anomaly characterized by abnormal root formation with normal crowns, treated with endodontics and extraction. A novel finding of contralateral incisor absence suggests systemic involvement in root development signaling pathways.

Key points
- Molar root-incisor malformation (MRIM) is a rare developmental anomaly with abnormal root formation and normal crowns.
- A 13-year-old patient was treated with endodontics for an incisor and extraction of a mobile first molar.
- Histological analysis of the extracted molar showed pathological changes in root and pulpal tissues.
- Congenital absence of the contralateral maxillary central incisor is a novel finding in this case.

Abstract
Abstract Molar root-incisor malformation (MRIM) is an uncommon developmental anomaly that is defined by an abnormal and incomplete root formation along with clinically normal crown morphology and texture, mostly involving permanent first molars and central incisors. A 13-year-old boy with typical clinical and radiographic features of MRIM, probably the first case in the Indian subcontinent, was treated with endodontic treatment of the maxillary incisor and extraction of the mobile mandibular left first molar. A systemic disease, which needed hospitalization and treatment at 1 month of age, may indicate an involvement of the signaling pathways related to root formation. H & E-stained sections of the extracted specimen were examined histologically to assess the pathological changes in the malformed root and pulpal tissues. The congenital absence of the contralateral maxillary central incisor is new finding and has not been mentioned in the literature. This case, and the novel clinical features, reminds general dental practitioners of the need to be aware of the diagnosis of MRIM and the need for a multidisciplinary treatment approach.
