Comparison of glass-ionomer (FUJI iii) and resin based fissure sealants (3M espe) one year clinical trial.
J Pak Dent Assoc Jan ;19(1):024-9.

OBJECTIVE: To compare and evaluate the retention rate, marginal integrity and surface structure of glass-ionomer [Fuji III] with resin based fissure sealants [3M ESPE]. METHODOLOGY:This study had a spilt mouth design using contralateral mandibular permanent first molars with well defined fissures and was conducted on 50 school children. First half of the children were randomly selected and applied glass-ionomer sealant on one side followed by resin-based sealant on contralateral tooth and vice versa. Quality evaluation was done by calibrated examiner on 4th, 8th and 12th month after application of sealant. Mann-Whitney test was done for the treatment difference and Wilcoxon signed ranks test was done for evaluation of sealants at different intervals and significance level was set at 0.05. RESULT: At 12th month evaluation, extensive loss of sealant was recorded in 44% of the glass-ionomer sealant, where as none of the tooth scored extensive loss for light cure resin-based sealant (p-0.0001). Light cure resin-based sealant (88%) had better adaptation compared to glass-ionomer sealant (28%) (p-0.05). Only 6% scored smooth surface in glass-ionomer compared to 66% in light cure resin-based sealant (p-0.001). CONCLUSION:Since the retention, marginal integrity and surface structure of glass-ionomer seems to be clearly lower than that of resin-based sealant, more clinical evidence of the effect of glass ionomer on caries development after the loss of the sealant material should be collected before glass-ionomer sealants can be recommended for general use.
