Objectives: The aim of this study was esthetic and mechanical evaluation of calcium and phosphate releasing and fluoride releasing hybrid restorative materials versus nanohybrid resin composite in posterior proximal carious lesions.
Materials and methods: A total of 45 participants with class II carious lesions were enrolled and randomly allocated. Lesions were randomly divided into three groups: Group 1 received ACTIVA Presto, Group 2 received GIOMER, and Group 3 received Neo Spectra ST. Under rubber dam isolation, cavities were prepared. Restorative material was placed according to the randomization sequence. Then finishing and polishing of restorations were achieved. Restorations were evaluated by using USPHS criteria at baseline, after 1, 3, 6 and 12 months.
Results: There was no statistically significant difference among the tested materials regarding the mechanical and esthetic criteria except color match.
Conclusions: Compared to Giomer and Neo Spectra ST, ACTIVA Presto showed comparable mechanical properties but inferior esthetic properties.
Clincal Relevance: The three categories of the restorative materials have similar clinical performance in posterior teeth.
