Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Resin-based sealant

A dental isolation device was used (Mr. Thisty One Step, Zirc Dental, Buffalo, MN, USA) and the treatments were conducted by one operator according to following steps; Group 1: Etching with 37% phosphoric acid for 30 s (i-GEL N, i-dental, Lithuania), rinsing for 30 s with air-water spray and drying with oil-free air for 15 s, resin sealant (Conceal F, SDI, Australia) application into the occlusal and buccal/palatal pits and fissures with direct placement syringe system and light curing with 460-500 nm wavelength halogen light unit (Hilux Dental Curing Light Unit 250, Benlioğlu Dental Inc, Turkey) for 20s on each surface.
