n Journal of Minimum Intervention in Dentistry - Cariostatic effect of resin-modified GlC versus compomers - a quantitative systematic review
Objectives To assess whether resin-modified glass ionomer cements have the same cariostatic effect than compomers.
Search strategy The trials were identified from a search of the PubMed database on 5 January 2009 using the terms: ((("Dental Carles:[Mesh] OR "Dental Carles Susceptibility"[Mesh] OR "Root Carles"(Mesh])) AND "Glass lanomer Cements"[Mesh]) AND "Compomers"[Mesh]. References of accepted articles were checked for additional studies sui1able tor inclusion.
Inclusion criteria Randomized / quasi-randomized control trial with relevance to review question including computable data; published in English.
Data collection and analysis The systematic literature search found 86 trials of which 8 were identified to be in line with the inclusion criteria. From the reviewed trials 28 individual datasets were extracted. A total of 24 datasets could be pooled into 5 separate meta-analyses. No meta-analysis was possible for the remaining 4 datasets due to clinical / methodological heterogeneity.
Main results The overall results show no difference between both materials, except for one trial indicating a 22% less chance of caries on resin-modified glass-ionomer restoration margins In permanent teeth after 6 years (RR 1.22; 95%Cl 1.06-1.40; P = 0.005). However these results may an overestimation due to selection bias effect.
Conclusions The overall evidence suggests that resin-modified glass ionomer cements have the same cariostatic effect than compomers.
