X-linked hypophosphataemic rickets is a hereditary metabolic disorder. The dental features include abscesses and swelling without caries or trauma. We present a case of familial hypophosphataemic rickets in an 11-year-old boy followed up for 60 months. We describe the treatment of multiple pulp necroses with apical periodontitis. Multiple pulp necroses with apical periodontitis were diagnosed in the anterior teeth. Ca(OH)2 apexification was performed; healing was evident over the next 60 months. The incisors, canines, and premolars exhibited shortened roots. To prevent pulp necrosis, regular check-ups included applications of fissure sealant and fluoride, vital testing, and radiography. The canines and premolar pulps retained vitality. Ca(OH)2 apexification followed by preventative follow-up was successful. The prognosis at the 60-month check-up was good.
