Exfoliation rates of primary molars submitted to three treatment protocols after 3.5 years

摘要

ObjectiveThe aim of the study was to evaluate the exfoliation pattern of primary molars treated according to three treatment protocols. The hypothesis tested was that there is no difference in the exfoliation pattern of primary molars treated according to conventional restorative treatment using amalgam (CRT), atraumatic restorative treatment using high-viscosity glass-ionomer (ART), and ultraconservative treatment (UCT). The latter consisted of restoring small cavities with ART and cleaning medium/large nonrestored cavities daily with toothpaste/toothbrush under supervision.
