Clinical effectiveness of resin‐modified glass ionomer–based fluoride varnish for preventing occlusal caries lesions in partially erupted permanent molars: A randomised active‐controlled trial

Abstract

Background: Deep pits and fissures in partially erupted permanent molars are vulnerable to dental caries.Aim: To assess the clinical effectiveness of resin-modified glass ionomer-based fluoride varnish (RMGI-F varnish: Clinpro XT™ varnish) in preventing occlusal caries lesions in partially erupted permanent first molars. Design:In this randomised active-controlled superiority trial with a single-blind parallel design, 74 children with 182 partially erupted first permanent molars were allocated into two groups: Group 1: RMGI-F varnish; and Group 2: GI sealant (active control), with an application of 0.1% sodium fluoride varnish for all other teeth. The primary outcome was ICDAS score ≥1 at 12 months of followup. Data were analysed using adjusted Chi-square test and GEE regression for binary outcomes.Results: Group 1 (15.7%) and Group 2 (13.8%) did not differ significantly in ICDAS ≥1 scores at 12 months of follow-up (adjusted χ 2 = 0.373, p = .541). There was no significant difference in retention between Group 1 (48.3%) and Group 2 (20.7%) at 12 months of follow-up (adjusted χ 2 = 0.1, p = .752). Mean application time per tooth (16 ± 5.9 vs 20.2 ± 5.4 min) was significantly different (t = 5.26, p = .014).Conclusions: RMGI-F varnish was not superior to GI sealant in preventing occlusal caries lesions in partially erupted molars.

Effect of Using Fiber Reinforcement Ribbond® System on Marginal Adaptation of Fluoride Releasing Restorations: An In Vitro Study

“…Several in vitro studies and clinical trials have proved the clinical efficacy of glass ionomers and resin-modified glass ionomers [6][7][8][9][10] . The main advantage of these materials is related to their fluoride releasing ability, which reduces the probability of developing new carious lesions adjacent to restorations (CAR) 11 .…”
