Abstract

Objective: The purpose of this study was to evaluate the clinical performance of composite restorations in root surface carious lesions with or without resin-modified glass ionomer lining.

Methods and materials: The sample consisted of 25 female and 14 male patients. A maximum of four lesions were included for each patient. After caries removal, the depth, length, and width of the cavity were measured. Lesions in the same patient were randomly divided into two groups, and the dentin surfaces were either lined with resin-modified glass ionomer liner (Glass Liner II) or left as they were. Self-etch adhesive (All Bond SE) was applied and cured for 20 seconds. All cavities were restored with nanohybrid anterior composite resin (Clearfil Majesty Esthetic). Two experienced clinicians evaluated the marginal adaptation (retention) rate, anatomic form, secondary caries, sensitivity, and marginal staining of restorations at the end of the first week and at six, 12, and 18 months posttreatment. The data were statistically analyzed using the Chi-square and two-way repeated measures tests.

Results: At the end of 18 months, a total of five lined and three unlined restorations were lost. There was no significant relationship between marginal adaptation and cavity lining at six, 12, and 18 months (p>0.05). Although marginal stainings of restorations were mostly localized, the total number of localized or generalized discolored restorations increased with time (p<0.001). There was a statistically significant relationship between marginal staining and smoking (p>0.05). There was no significant relationship between marginal staining and frequency of toothbrushing at six, 12, and 18 months (p=0.286, p=0.098, and p=0.408, respectively).

Conclusion: Within the limitations of this study, both restorative applications were accepted as clinically appropriate.
