ABSTRACT


Aim

To report on the absence of carious lesions at margins of glass ionomer cement (GIC) and amalgam
restorations.

Methods

Six Anglophone and 1 Lusophone databases were searched for articles up to 5 January 2008.
Inclusion criteria for articles were: (i) titles/abstracts relevant to topic; (ii) published in English, Portuguese or Spanish
language; (iii) reporting on a randomised control trial. Exclusion criteria were: (i) insufficient random allocation of study
subjects (ii) operator and subject not blinded, where appropriate; (iii) not all entered subjects accounted for at trial
conclusion; (iv) subjects of both groups not followed up the same way. Articles were accepted only if they complied with all
the criteria. Ten articles complied with the inclusion criteria and were selected for review. From these 4 were rejected and 6
articles reporting on 8 separate studies accepted. Due to aspects of heterogeneity, studies were sub-grouped before meta-
analysis.

Results

Significantly less carious lesions were observed on single-surface GIC restorations in permanent teeth
after 6 years as compared to restorations with amalgam (OR 2.64 - CI 95 1.39 - 5.03, p 0.003). No studies
investigating multiple-surface restorations on permanent teeth were identified. Studies investigating carious lesions at
margins of restorations in primary teeth showed no difference between both materials after 3 and 8 years. CONCLUSIONS:
Carious lesions at margins of single-surface GIC restorations are less common than with amalgam fillings after 6 years in
permanent teeth. No difference was observed in primary teeth. More trials are needed in order to confirm these
results.
