The aim of this clinical study is to compare and evaluate the Success of Selective Caries vs Stepwise Caries Removal Techniques in treatment of dental caries.

The patient will be selected as per the pre-defined eligibility criteria. Written informed consent will be taken from each consenting participant. Initial caries excavation will be done under rubber dam isolation. The patient will then be randomly allocated to two groups: selective removal to soft dentin or stepwise caries removal. Composite restoration with glass ionomer liner will be then placed in both groups. Additional complete caries excavation will be done in the stepwise caries removal group after six months.

Inclusion Criteria:

• Outpatient in age range of 18yr-60yr
• Permanent mandibular posterior teeth with deep caries
• Caries extending to >3/4 of dentin with a layer of sound dentin between pulp and carious tissue as seen on radiograph
• Positive response to cold test and electric pulp test

Exclusion Criteria:

• Any general disease affecting the caries e.g. patient under head and neck radiotherapy
• Patients with immuno-compromised status
• Tooth with fracture line, cracks.
