Abstract
Purpose: To evaluate reliability of Q-ray view (Aiobio Inc,. Seoul, Korea) for assessing retention status of pit and fissure sealants.
Methods: Pit and fissure sealants of 58 permanent molars from 15 third-grade students were examined. Posterior teeth with ≥1 pit and fissure sealants applied to the occlusal surface for >6 months were examined. The teeth were examined using traditional visual-tactile assessments and combined Q-ray view. Pit and fissure sealants were evaluated by assessing marginal plaque, marginal discoloration, marginal integrity, retention, and presence of caries. Fleiss kappa and Cohen's kappa values were calculated to compare inter- and intrarater agreements between visual-tactile and combined Q-ray view assessments.
Results: Regarding interrater agreement in visual-tactile assessments, K values of Cohen's kappa for marginal plaque, marginal discoloration, and presence of caries were 0.22?0.57, 0.36?0.57, and 0.43?0.61, respectively, and agreements ranged from slight to moderate. When combined with Q-ray view, the values were 0.81?0.89, 0.69?0.88, and 0.80?0.90, respectively, and agreements ranged from substantial to nearly perfect level, indicating statistical significance. Marginal plaque (0.81?0.83), marginal discoloration (0.57?0.89), and presence of caries (0.69?0.91) showed higher agreements in combined Q-ray view than in visual-tactile assessments, and kappa values of marginal plaques were significantly higher in combined Q-ray view than in visual-tactile assessments.
Conclusion: Evaluating retention status of pit and fissure sealants using Q-ray view showed higher reliability than using visual/tactile assessments for marginal plaque, marginal discoloration, and presence of caries. Therefore, Q-ray view may be used to assess the retention status of pit and fissure sealants.
