The aim of this clinical study was to evaluate the effects of different isolation methods and material filler ratios on the retention rates of two different fluoride-containing fissure sealants over an 18-month period. Methods: A total of 100 children (200 teeth) participated in this randomized, single-blind, split-mouth clinical trial. The mandibular permanent first molars of each participant were divided into two groups: one receiving a highly filled fluoride-releasing fissure sealant (Fissurit FX, Voco, Germany), and the other an unfilled fluoride-releasing sealant (Teethmate F-1, Kuraray, Germany). Each material group was also divided into two subgroups based on the isolation method used: rubber dam or cotton roll isolation. Sealant retention rates were evaluated at 6-, 12-, and 18-month follow-up visits. Data were statistically analyzed using a 0.05 significance level.

The retention rates of two different resin-based fissure sealant materials (a pit and fissure sealant containing high-filler fluoride and a pit and fissure sealant containing non-filler fluoride)
Timeframe: The evaluation of pit-and-fissure sealants was conducted to record the presence of caries lesions and sealant retention at 6-, 12-, and 18-month follow-up visits.
