Aim of the study:

To evaluate clinical and radiographic success rates of silver diamine fluoride versus mineral trioxide aggregate as indirect pulp capping agents in deeply carious young first permanent molars.

Indirect pulp treatment has become a common maneuver in vital pulp therapy in recent years and is a procedure performed in teeth with deep carious lesions approximating the pulp but without any signs or symptoms of irreversible pulpal changes.

Silver Diamine Fluoride is used to arrest caries lesions in primary teeth but according to the AAPD,2021 more research is needed on the use of SDF to arrest caries lesions in permanent teeth.

Inclusion Criteria:

• Patient and parent showing cooperation and compliance.
• Children 9-14 years old
• Vital deeply carious young first permanent molar(s) with complete root formation
• Asymptomatic teeth or without clinical symptoms of spontaneous pain
• Both genders will be included.

Exclusion Criteria:

• Children unable to return for recall visits.
• Any clinical signs of irreversible pulpitis or pulp necrosis (spontaneous pain, pain on percussion, abscess, sinus).
• Any radiographic sign of irreversible pulp pathologies or pulp necrosis (periapical radiolucency, internal or external root resorption)

Two blinded (patient, radiographic assessor of results)
