Post-Operative Sensitivity in Teeth Restored with Posterior Dental Composites Using Self-Etch and Total-Etch Adhesives.
J Pak Dent Assoc Jan ;24(1):22-7.

ABSTRACT: To compare the level of post-operative sensitivity (POS) in teeth restored with posterior dental composite restorations using self-etch and total-etch adhesive systems. METHODOLOGY: Eighty patients were selected with small class I carious lesions on premolars from the Out Patient Department of Altamash Dental Hospital, Karachi. Forty patients were placed in treatment Group I (Self Etch: SE) and 40 in control group: Group II (Total Etch: TE). Composite restorations were placed in the cavities by using SE and TE adhesives respectively. Patients were followed for a week and POS was recorded in response to cold stimulus from an ice stick on Visual Analog Scale after one, four and seven days of restoration. Data was analyzed using SPSS version 12.0. RESULTS:Statistically significant difference was found in the level of POS in both groups (SE and TE) between the Day one and later follow up visits. For postoperative day-7, VAS score were significantly lower than that in post-operative day-1 among both groups. CONCLUSION:TE adhesives showed significantly less POS compared to SE group during the first four days of restoration placement after which the difference between the groups faded. The study results showed that postoperative sensitivity was found with both total-etch adhesive and self-etch adhesive till one week post-operatively. A reduction in sensitivity was found in both groups from day one to day seven. KEY WORDS: Post-operative sensitivity, self-etch adhesives, total-etch adhesives, composites.
