Sigara Kullanan Ve Kullanmayan Bireylerde Universal Adezivin Üç Farklı Modu Kullanılarak Yerleştirilen Servikal Kompozit Restorasyonların Bir Yıllık Klinik Takibi

Abstract

The aim of this clinical study was to evaluate the one-year clinical performance of resin composite restorations using an universal adhesive (G-Premio BOND; GC) with three different modes in non-carious cervical lesions placed in smokers and non-smokers using modified USPHS criteria, gingival index, plaque index and dentin hypersensitivity. A total of 228 non-carious cervical lesions in 47 patients (nonsmokers; 24, smokers;23) with at least 3 non-carious cervical lesions were restored in this study. Six groups were formed according to patients’ smoking habits and universal adhesive application modes (Etch&Rinse-ER, Selective-Etch-SLE or Self-Etch-SE). The resin composite (Essentia, GC) was placed incrementally by a single operator. Two experienced and calibrated examiners evaluated the restorations at one week (baseline), 3, 6 and 12 months using modified USPHS criteria, gingival index, plaque index and dentin hypersensitivity. Generalized estimating equations (GEE) method was used for both qualitative and quantitative variables to examine changes in time in groups and different modes (p<0,05). The recall rate of patients was 100%. In non-smokers, one restoration from SE group at 6 months and one from ER group were lost at 12 months. No statistical difference was observed between the groups at each recall (p>0,05). According to the modified USPHS criteria, statistically significant differences was only observed in marginal discoloration at the 12-month recall between smoking and non-smoking groups (p<0,05). When the risk of marginal discoloration was evaluated at 12 months, it was found to be 2,72 (95% CI 1,36-5,45) times higher in smokers than non-smokers (p <0,05). For both smokers and non-smokers groups, there were statistically significant differences between the baseline and 3-,6- and 12-month recall in terms of marginal discoloration (p<0,05). The rate of deterioration in marginal adaptation was higher than the baseline at 12 months (p<0,001). When the different modes of universal adhesive were evaluated according to the modified USPHS criteria, no statistically significant difference was detected (p> 0,05). For smokers’ group, pre- and postoperative sensitivity (VAS score) was found to be statistically higher than non-smokers at all evaluation periods (p=0,031). It can be concluded that smoking had an effect on the clinical performance of restorative materials and dentin hypersensitivity in individuals.
