Influence of Isolation Technique on the Survival of Resin-Modified Glass-Ionomer Restorations in Primary Molars: A 9-Months Randomized Controlled Trial

Objective:  T o compare the survival of occlusal and occlusal-proximal restorations performed with resin-modified glass-ionomer cement (RMGIC) in deciduous molars using rubber dam cotton rolls isolation .  Material Methods:  Ninety-two patients were included 200 cavitated or occlusoproximal dentin caries lesions randomized into two groups: (n = 100) RMGIC placed. At baseline follow-up visit, presence, severity activity registered. Two independent, blinded examiners evaluated treated teeth clinically USPHS criteria radiographically after 9 months. Descriptive analysis, curve (log-rank test) Cox regression to assess risk factors related failure.  Results: Out 179 (92 group 87 group) at 9-month period. No lesion progression was observed radiographically. The overall treatment success rate 85.47% (83.47% for 87.35 group). significant difference between methods log-rank test (p 0.16). showed no failure Conclusion:  No found a
