Clinical And Radiographic Evaluation Of Nano-Propolis, Nano-Curcumin and MTA as Direct Pulp Capping Agents in Young Permanant Teeth

Inclusion Criteria: * Young permanent teeth with deep carious lesions that led to a caries-exposed pulp after spoon excavation and a diagnosis of reversible pulpitis. * The tooth has a pulp exposure caused by trauma that occurred within 48 h. Exclusion Criteria: * The patient has a history of systemic disease that interferes with pulp healing. * The tooth has clinical signs and symptoms of irreversible pulpitis, e.g., spontaneous throbbing pain, tenderness to percussion, abnormal tooth mobility, swelling, or sinus tract. * Radiographic evidence of internal or external resorption, inter-radicular bone loss, or periapical pathology. * The tooth was non-restorable. During the study, if any symptoms of irreversible pulpitis, apical periodontitis, or infection occurred, the patients received the appropriate treatment following the institute protocol, including regenerative and root canal treatment.
