Effect of Different Resin Composite Packing Techniques on Pulp Condition (Randomized Clinical Trial)
Sponsor: October 6 University
Summary
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.

Conditions
Interventions
Sonic Fill bulk fill resin composite
The SonicFill bulk-fill resin composite is delivered directly into the cavity preparation using its specialized, ultrasonically activated handpiece. The material is placed in a single bulk increment of up to 5 mm, completely filling the cavity to the occlusal margin. Once the sonic activation stops, the material reverts to a sculptable, non-slumping consistency, allowing immediate anatomical contouring. The entire bulk increment is then light-cured from the occlusal surface according to the manufacturer's recommended exposure time and intensity
SDR flowable bulk fill resin composite
SDR bulk-fill flowable composite is dispensed directly into the cavity using the manufacturer's syringe tip, starting from the deepest part of the preparation to avoid air entrapment. Due to its self-leveling properties and low polymerization stress, it is placed in a single bulk increment of up to 4 mm, leaving approximately 1.5-2 mm of occlusal space for the capping layer. The material is then light-cured. The remaining occlusal volume is restored using a conventional packable resin composite to act as the wear-resistant enamel replacement. Then the capping layer is adapted to the cavosurface margins, anatomically contoured to replicate correct tooth morphology, and light-cured.
