Clinical Evaluation of Giomer and Resin-based Fissure Sealants

One-hundred FPMs with MIH which were indicated for non-invasive fissure sealant were selected in 39 children (between 6-12 years). Using a split mouth design, the FPMs were randomized into two groups; Group 1: resin sealant (Conceal F); Group 2: giomer sealant (BeautiSealant) and dental isolation device was used during the procedure (Mr. Thursty). Clinical evaluation was performed by two blinded examiners using the United States Public Health Service (USPHS) criteria to assess anatomical form, marginal adaptation, surface texture, marginal discoloration, retention and secondary caries at 1, 3, 6 and 12 months. Statistical analysis was performed using SPSS 20.0 software (IBM Corp., Chicago, IL, USA) and the level of significance was set at p<0.05. The association between independent variable (groups) and dependent variable (USPHS scores) was evaluated with Fisher's exact test. The crosstabulation of the categorical data regarding the groups were analyzed with chi-square test or Fisher's exact test. The Log-rank test and Kaplan-Meier analysis were used to calculate and compare the cumulative survival rates of the sealants.
