Abstract
The purpose of this study was to compare different types of pit and fissure sealant Ketacbond (Conventional Glass iono mer cement) GIC, Vitremer (Resin modified glass ionomer) RMGI, and Delton Resin sealant (RS) for retention and caries prevention after 6, 12 and 18 Months.
Two hundred and ninety three sound first permanent molars in children six to eight years of age children were divided into three groups Group 1, (n = 98) teeth were sealed using ketacbond GIC (Conventional Glass ionomer cement), Group II: (n= 97) teeth were sealed using Vitremer RMGI (Resin modified glass ionomer), Group III: (n = 98) teeth were sealed using Delton(RS) Resin sealant. All teeth were free from caries, unsealed, and the sealing materials were selected randomly. All teeth were sealed after prophylaxis of the occlusal surfaces, washing for 20 seconds, dried for 30 seconds, and isolated using cotton rolls to prevent salivary contamination. The three sealing materials were prepared and applied to the conditioned teeth according to instruction of the manufactures. The collected data of the three groups were calculated using qui-square test to evaluate and compare the retention and prevalence of caries between the different groups after 6, 12 and 18 Months.
The results of the three groups were 4.1, 23.5, and 96.9% respectively, while it was 6.2, 12.2 and 3.1 % for partial retention 1, and 9.3, 12.2, and zero
% for partial retention 2, at the same time interval, the total loss of sealant were 80.4, 34.7, and zero. A statistical significant difference was found on the prevalence of retention level after 18 months between the three groups. One carious lesion was detected in group 3, two in-group 1 after 18 month, while no carious lesions were detected in group 2.
From the results of this study it can be concluded that pit and fissure sealant is safe, preventive, effective, non-surgical, and non-expens ive procedure, and should be applied specially to molars at risk to caries. Delton a resin based sealant (RS) presented better retention rate than Vitremer (RMGI) and followed by Ketac -bond (GIC). Glass ionomer cement and modified resin glass ionomers can be used as pit and fissure sealant especially when c aries prevention is neede d
