The goal of this clinical trial is to evalute the effect of different resin composite packing techniques on pulpal condition in patient with deep carious occlusal cavities in their molar teeth. The main questions it aims to answer are:
* Do composite packing technquies cause pulpal inflammatory response ?
* Do composite packing technquies cause post operative pain ? Researchers will compare elastic cavity liner packing techniques to sonic activated and flowable bulk packing techniques to see their effect on pulp condition.
Participants will :
* Provide an honest medial and dental history to undergo the restorative procedures .
* Report subjective symptons.
* Attend all scheduled follow-ups visit for pulp assessment.
