This is a randomized clinical trial that aims to compare the clinical and radiographic success of Hall technique (HT) versus Indirect pulp capping (IPC) for the management of deep dentinal caries in primary molars and to compare the child and parent acceptance of HT versus IPC for the management of deep dentinal caries in primary molars.

This is a randomized clinical trial that aims to compare the clinical and radiographic success of Hall technique (HT) versus Indirect pulp capping (IPC) for the management of deep dentinal caries in primary molars and to compare the child and parent acceptance of HT versus IPC for the management of deep dentinal caries in primary molars.

Children aged 4-9 years old presenting with occlusal or proximal carious lesions of primary molars radiographically extending into the inner third or quarter of dentin will be invited to participate in this study. Patients will be randomized into two treatment groups using online block randomization technique (block of 6) and sealed envelope techniques. Time taken for clinical procedure will be recorded by a research assistant prospectively from the time the child sits on the dental chair till the end of procedure. Child pain perception will be recorded during intervention by a blinded research assistant using the Sound Eye Motor scale (SEM). Parental preference and child acceptance for each procedure will be recorded immediately after treatment using parent and child questionnaires. Clinical and radiographic success, and patient satisfaction will be evaluated at 6 and 12 months follow up.

Inclusion Criteria:

• Fit and healthy.
• Occlusal or proximal carious lesions on primary molars radiographically extending into the inner third or quarter of dentin.

• No tenderness to percussion, or pathological mobility.
• No radiographic evidence of interradicular/ periapical radiolucency.
• Radiographic evidence of a radiopaque dentin layer between the radiolucent caries lesion and the dental pulp
• Tooth is restorable.
• Patient has good level of cooperation for the intended procedure.
• Parents consented for their children to be included in the study.

Exclusion Criteria:

• Medically compromised children.
• Irreversible pulpitis or pulp necrosis.
• Soft and/or hard tissue pathology.
• Furcal/ periapical pathology.
• Root resorption exceeding one third of the root.
• Pathological mobility.
• Patient has poor level of cooperation for the intended procedure
