Effectiveness of single-surface ART restorations in the permanent dentition: a meta-analysis

J Dent Res. 2004 Feb;83(2):120-3. doi: 10.1177/154405910408300207.


Over the past few years, there has been an increase in the number of studies reporting on various aspects of the Atraumatic Restorative Treatment (ART) approach. Five randomized clinical trials in which ART restorations with glass ionomers were compared with amalgam restorations in permanent teeth for a maximum period of 3 yrs constituted the database. This meta-analysis divided the publications into 'early' (1987-1992) and 'late' (1995-) studies on the basis of improvements in the approach. The analysis showed that, in the 'early' studies, single-surface amalgam restorations survived statistically significantly longer than comparable ART restorations after 1, 2, and 3 yrs. This trend did not continue into the late group of studies; no statistically significant difference between the 2 types of restorations was found. Based on the available data, it appears that there is no difference in survival results between single-surface ART restorations and amalgam restorations in permanent teeth over the first 3 yrs.
