Objectives To compare, within the second year, the effects of composite resin and stainless steel crowns (SSCs) on the restoration of primary molars with caries, pulpitis and periapical periodontitis in a prospective study. Methods In this study, all primary molars with caries, pulpitis and periapical periodontitis were treated and restored using either light-curing composite resin or SSCs under general anaesthesia. Data on every treated primary tooth were recorded on every visit. Patients were separated into 12- and 24-month groups based on the data from the operation; the loss of restoration, margin failures, recurrent caries, gingival health, restoration status, adjacent permanent teeth eruption failures were recorded in a prospective manner. Data were analysed using chi-square. Results A total of 84 patients, 556 primary molars including 276 SSCs and 280 light-cured composite resins were included in this study. There were significant differences in restoration maintenance, margin problems and recurrent caries prospectively. Conclusions SSCs are superior to composite resin with respect to restoration maintenance, margin problems and recurrent caries. SSCs are clinically successful restorations in primary molars especially in high caries risk children.
