The effect of selective caries cleaning and total caries cleaning on pulp health and post operative pain in teeth with deep caries will be investigated.

Inclusion Criteria:

• Patients aged ≥15 years with bilateral deep carious mature permanent teeth.
• Positive vitality test (cold sensitivity).
• No spontaneous pain or periapical radiolucency.
• Willingness to attend 6- and 12-month follow-ups

Exclusion Criteria:

• Uncontrolled systemic diseases Pregnancy or allergy to dental materials used Teeth with irreversible pulpitis (spontaneous pain, necrosis) Non-restorable teeth (fractures, extensive decay)

Patients and outcome assessors were blinded to the intervention groups. The operator was not blinded due to the visible differences between total and selective caries removal techniques.
