Different Modes of Universal Adhesive in Smokers and Non-Smokers

Hacettepe University47 enrolled

Overview

The aim of the study was to evaluate the influence of smoking on the clinical performance of a universal adhesive used with different application modes in non-carious cervical lesions.

Forty-seven patients (having at least three noncarious cervical lesions) were participated in this study. After allocation of patients into 2 groups according to their smoking habits (non-smokers; 24, smokers;23), lesions in each patient were restored with a resin composite, (Essentia, GC) using a universal adhesive G-Premio Bond and phosphoric acid (i-Dental) in three different application modes (etch\&rinse, selective-etch or self-etch). The restorative treatments were performed by single operator. Two experienced and calibrated examiners evaluated the restorations for retention, marginal discoloration, marginal adaptation, color match, postoperative sensitivity and secondary caries at one week (baseline), at 6-, 12, and 18 months using modified USPHS criteria.While the USPHS criteria measure the clinical performance of the restorative material, it scores according to three different degrees;Alpha:The restoration is clinically perfect. Bravo:All features of the restoration are sufficient, need not be renewed. Charlie: the restoration is clinically unsuccessful, unacceptable. The gingival and plaque index were also assessed with a periodontal probe.

Interventions

G-Premio Bond in etch&rinse modeDEVICE

The phosphoric acid gel was applied to enamel and dentin washed for 5s and was dried gently with air spray. The adhesive system was applied to enamel and dentin surfaces and leave it in place for 10s.

G-Premio Bond in selective-etch modeDEVICE

The phosphoric acid was applied only on enamel for 10-15s then washed and was gently dried with air spray. The adhesive system was applied to enamel and dentin surfaces.

G-Premio Bond in self-etch modeDEVICE

The adhesive system was applied to the enamel and dentin surfaces.

Retention

According to the usphs criteria, retention indicates whether a restorative material is functional in the oral environment, and is the most important criterion by which we can evaluate the success of the material. Alpha: Retained. Charlie: Mobile or missing; clinically unacceptable.
