A Two-Year Clinical Evaluation of Glass Ionomer and Ormocer Based Fissure Sealants

Abstract

The objective of the present study provides further data comparing retention, marginal integrity and caries preventive effects of two fissure sealants (glass ionomer based; GC Fuji VII Capsule [Fuji VII] and ormocer based; Admira Seal [AS]) in children. This study was designed as a randomized single-blind clinical trial. The permanent first molars (PFMs) of 50 children, 7-13 years of age (mean age: 8.9<1.3 years), were sealed with a split-mouth design. Fissure sealants applied to the PFMs according to the manufacturer's recommendations by one pediatric dentist. Clinical evaluation of the sealants was carried out to record retention, marginal integrity and presence of caries at 6, 12, 18 and 24 months after placement by the other pediatric dentist. Kaplan-Meier survival analysis and Cox's regression models were used to estimate the probability of two sealants success. Results: Alpha and Bravo retention rates at the end of follow-up were 13% and 80% for Fuji VII and 3% and 83% for AS, respectively. For retention and marginal integrity between fissure sealants was found similar survival rates (p>0.05). After 24 months, presence of caries was 16% for Fuji VII and 32% for AS (p<0.05). Conclusion: Fuji VII and AS exhibited similar retention and marginal integrity during 24 months. However, Fuji VII was showed better results than AS for caries preventive effect. Consequently, Fuji VII sealants may be a better choice for preventing occlusal caries.

A 48-month randomized controlled trial of caries prevention effect of a one-time application of glass ionomer sealant versus resin sealant

“…Choosing between a resin sealant and a glass ionomer sealant will be strongly influenced by clinical considerations, including the prevalence or risk of caries in the child. In this study, the prevalence of caries in the participants was high compared with previous studies 27,32,38,39) and the GIS group performed better than the RS group in preventing caries.…”

Evidence-based clinical practice guideline for the use of pit-and-fissure sealants

“…Summary of findings. Data from 10 randomized controlled trials [40][41][42][43][44][45][46][47][48][49] included in the meta-analysis suggest that in children and adolescents with sound occlusal surfaces, the use of GI sealants compared with resin-based sealants may reduce the incidence of occlusal carious lesions in permanent molars by 37% after 2 to 3 years of follow-up (OR, 0.71; 95% CI, 0.32-1.57); however, this difference was not statistically significant (P ¼ .39) (eTable 3, available online at the end of this article). In absolute terms, for a population with a caries baseline risk (prevalence) of 30%, this means that use of a GI sealant would prevent 67 carious lesions out of 1,000 sealant applications (95% CI, 102 more-179 fewer lesions) compared with using a resin-based sealant after 2 to 3 years of follow-up; however, this difference was not statistically significant.…”

Retention evaluation of two glass ionomer cement sealants: six-month clinical follow-up

“…Systematic reviews, randomized controlled clinical trials and consulted Meta-analyzes emphasize that the pit and fissure ionomer sealing is highly effective in preventing caries lesions and treatment of incipient lesions 8,[10][11][12][13][14][15][16] .…”
