The aim of this in vivo study was to evaluate the clinical 1 year follow-up of silica and
 flouroapatite reinforced glass carbomer filling material.

 In this study, total of 100 (46 class I, 54 class II) restorations were performed in 36
 patients. All cavities were prepared conventionally. Half of the restorations were restored
 with nano composite resin (Tokuyama Estelite, Tokuyama Dental, Japan) and the other half were
 restored with glass carbomer material (GCP Dental, The Netherlands). Rubber-dam was used for
 isolation. Before the replacement of composite restorations, enamel edges were etched
 according to selective etching method. Then universal adhesive system was applied. Composite
 resin was applied to the cavity in 2 mm layers by incramental technique. Glass carbomer was
 placed with bulk technique by applying finger pressure with surface covering. Composite
 restorations were polymerized with LED light curing unit. Glass carbomer restorations were
 cured its own special curing unit. Restorations were evaluated with modified USPHS criteria
 at the end of the first week, 6 months and 12 months. Data were analyzed using Fisher's Exact
 Chi-Square test, Fisher Freeman Halton Test and Continuity (Yates) Correction. Wilcoxon sign
 test was used for intra-group comparisons of the parameters. Statistically significance was
 evaluated at p <0.05.
