A 12-year-old patient presented with a severe delay of eruption in permanent maxillary and mandibular incisors. On examination, there was over-retained primary teeth and delayed eruption of permanent teeth. Retained primary teeth showed light yellow discolouration whereas permanent teeth were distinct yellow with thin or little enamel. Subsequent imaging revealed all the premolars except maxillary left first premolar showed signs of intra-alveolar coronal resorption, nephrocalcinosis with bilateral multiple calculi and small papillary tip calcifications, marked increase in alkaline phosphatase. Subsequent dental treatment for restoring the functional and aesthetic requirement followed by appropriate treatment for renal problem was undertaken.
