Brief summary

The purpose of this study is to compare the onset and severity of pain and postoperative sensitivity in patients after using conventional nanohybrid and bulkfill composites Null Hypothesis: There is no significant difference in mean postoperative sensitivity exhibited with conventional nano-hybrid versus bulkfill composites in mandibular molars with class 1 cavity.

Detailed description

The study will include 79 patients with class 1 carious mandibular molars. Teeth are divided into two groups based on composite placement techniques. In group 1, 39 patients are restored with conventional nanohybrid composites using an incremental layering technique. In group 2, 40 patients are restored with bulk-fill composites containing a single increment. After taking a brief history, informed consent will be taken from patients. The depth of the cavity will be determined using a periodontal probe not extending more than 3 mm. Preoperatively, pulp vitality will be assessed using the cold thermal test. A preoperative radiograph will also be taken. A rubber dam will be used. The cavity will be prepared and a selective etch technique will be used. Patients will be recalled after 24 hours and 1 week, thermal cold tests will be performed and a questionnaire containing the Numerical Rating Scale will be given to each patient for evaluation of post-operative pain felt after 24 hours and 1 week.
