Abstract
BACKGROUND: Clinical studies comparing retention rates of pit and fissure sealants placed under Isolite, rubber dam, and cotton roll combined have not been conducted until now. AIM: To evaluate the retention rate of pit and fissure sealants (PFS) placed under three different isolation techniques (Isolite system [IS], rubber dam isolation [RDI], and cotton roll isolation [CRI]). DESIGN: One hundred and forty-four teeth from 48 children aged 6-15 years attending paediatric dental clinics at King Saud University in Saudi Arabia were randomized to receive three PFS using three isolation techniques. The children that met the inclusion criteria were randomized by a simple block random allocation method. All PFS were placed by an operator and evaluated by a blinded evaluator. The evaluation scores were recorded at baseline and followed up over a period of 12-22 months. RESULTS: The children's mean age was 8.58 ± 1.93 years. Seven patients were lost to follow-up. A total of 123 teeth were clinically evaluated; of these teeth, 22% had completely retained sealants, whereas approximately 66% had a partial loss of sealants, and approximately 12% had a complete loss of sealants. There were, however, no significant differences between the three isolation techniques on the retention rate of pit and fissure sealant. CONCLUSION: The types of isolation had no impact on the retention rate of pit and fissure sealant.
