Evaluation and comparison of silorane resin composite to glass ionomer in occluso-proximal restorations of primary molars: A randomized controlled trial.

Objective: In general, proximal restorations of primary molars fracture, so it is vital to study the new materials that could solve this problem. Hence, the present trial assessed the success of occluso-proximal atraumatic restorative treatment (ART) restorations using silorane and glass ionomer cement (GIC) in carious primary molars for a period of 2 years.

Materials and methods: One hundred and ninety-two children between the age group of 4 and 9 years were randomly allocated to GIC or silorane. In the clinical set up, they were treated by a pediatric dentist, and their restorations were evaluated at 3, 6, 12, 18, and 24 months. The primary outcome was the survival of restoration, which was analyzed using the Kaplan-Meier and superior Cox regression models. As a sensitivity analysis, intention-to-treat (ITT) was executed. Sex, age, molar, jaw, cavity volume, and caries incidence were the independent variables.

Results: The restoration survival after 24 months for GIC and silorane was 82.75% and 88.88%, respectively, whereas ITT analysis showed a success of 84.37% and 89.58% for GIC and silorane, respectively.

Conclusion: With regard to longevity, there was no statistically significant difference between silorane and GIC in primary molar occlusoproximal ART restorations.
