Abstract
AbstractA 9-year-old child reported with chief complaint of broken teeth (11 and 21) and discolored tooth (21). Diagnosis of pulp necrosis with apical periodontitis with regard to 11 and 21 was made based on clinical and radiographic examination. The canals were irrigated with sodium hypochlorite and then dried with paper points. Disinfection of canals was done using photoactivated disinfection (PAD). Platelet-rich fibrin (PRF) was placed as scaffold in canals till the cementoenamel junction (CEJ). A 2-mm thick layer of white MTA was placed, followed by dual seal using glass–ionomer cement (GIC) and composite resin. Follow-up examination was done for 1 year. Clinical examination showed no pain, tenderness on percussion, and no mobility and improvement in color of teeth. Radiographic evaluation revealed continued thickening of the dentinal walls, root lengthening, regression of the periapical lesion, and partial apical closure. This report of pulp revascularization shows that disinfection with photodynamic therapy combined with PRF resulted in satisfactory root development in necrotic immature teeth.
