Summary

This study is designed to compare two modern techniques used to restore decayed back teeth with tooth-colored filling materials. Some patients experience temporary discomfort or sensitivity after these types of dental treatments. The purpose of this study is to learn whether one technique may help reduce this short-term sensitivity compared to the other.

Adults who need fillings on both sides of their mouth are invited to participate. Each patient will receive one filling using each technique, placed in different teeth during the same appointment. The procedures will be performed using standard clinical methods and materials.

After treatment, participants will be contacted by telephone to report any discomfort at several time points during the first week. The interviewer will not know which technique was used for each tooth to ensure unbiased reporting. This information will help dentists better understand how these techniques affect patients' comfort in the days following treatment.

Conditions

  • Postoperative Tooth Sensitivity Following Class II Composite Restorations

Interventions

PROCEDURE

Snow-plow restorative technique

The snow-plow technique involves placing a thin layer of uncured flowable bulk-fill resin on the gingival floor of a Class II cavity, immediately followed by placement of a packable bulk-fill composite. Both materials are light-cured simultaneously, allowing the flowable resin to fill voids and improve marginal adaptation.

PROCEDURE

Resin coating restorative technique

The resin coating technique involves applying and light-curing a thin layer of flowable bulk-fill resin after adhesive application to create a stress-absorbing layer on dentin (resin coating), followed by restoration with packable bulk-fill composite. This approach aims to protect the dentin, enhance bond stability, and reduce postoperative sensitivity
