Aim: The study aimed to evaluate the microleakage of nano-filled resin-modified glass ionomer restorative (nano-filled RMGI) in comparison with that of conventional glass ionomer cement (CGIC), and resin-modified glass ionomer cement (RMGIC). Materials and Methods: Forty-five standardized Class V cavity preparations were prepared on sound extracted human molar teeth. Teeth were randomly assigned to three experimental groups of 15 teeth each and restored as follows: Group 1, CGIC; Group 2, RMGIC; and Group 3, nano-filled RMGI. The specimens were placed in a solution of 2% Rhodamine-B dye for 24 h at room temperature under vacuum. Staining along the tooth restoration interface was recorded. Results were analyzed using Kruskal-Wallis and Wilcoxon tests. Results: There were no statistically significant differences in dye leakage between all the three restorative materials for occlusal margins (P = 0.464). Group 3 showed significantly less microleakage compared to Group 1 (P = 0.007) and Group 2 (P = 0.040) at the gingival margins. The degree of microleakage in the gingival margins of each group was more than that found in occlusal margins. Conclusions: No material was able to completely eliminate microleakage at enamel, dentin, or cementum margin. Nano-filled RMGI showed least microleakage compared to other two cements at gingival margins.
Clinical Relevance to Interdisciplinary Dentistry
- Cervical lesions have been a restorative challenge for dentists for many years.
- An interdisciplinary treatment approach is the appropriate choice in cases where there is gingival recession and cervical lesions.
- Glass ionomer cements have been commonly used for restoration of cervical lesions.
- Nano-filled resin-modified glass ionomer cement can be used for the restoration of cervical lesions, as it has a better marginal sealing ability compared to conventional glass ionomer and resin-modified glass ionomer cements.
