PLATELET RICH FIBRIN SCAFFOLD COMBINED WITH INDUCED BLOOD CLOT IN PULP REVASCULARIZATION OF NECROTIC IMMATURE PERMANENT TEETH WITH CHRONIC PERIAPICAL LESIONS: A CASE SERIES

ABSTRACT Background: Traumatized non-vital permanent teeth with incomplete root formation and divergent apices present particular challenges to clinicians during management traditional approaches. Objectives: This report described the outcomes of pulp revascularization three traumatized immature necrotic using platelet-rich fibrin scaffold combined induced blood clot. Materials Methods: Three patients (two boys aged 8 11 years one girl 13 years) were presented maxillary incisors pulps. Access cavities prepared canals gently irrigated 1.5% sodium hypochlorite (20 mL/ 5 min). Calcium hydroxide paste was applied mm short apex temporized intermediate restorative material. At following appointment after two weeks, treated by protocol Platelet rich clot cases clinically radiographically followed up eighteen months. Results: The asymptomatic at all follow-up periods. Cone Beam Computed Tomography (CBCT) images revealed evidence maturation healing periapical lesions. Calcific intra-canal deposits noted middle apical thirds canals. Conclusions: Pulp procedure showed elongation, increased dentin thickness resolution
