Abstract The aim of this prospective study, conducted in a dental practice was to evaluate the success rate of a hybrid composite material (TPH-Spectrum; Dentsply DeTrey, Konstanz, Germany) and a polyacid-modified composite resin (Compoglass; Vivadent, Schaan, Liechtenstein) in Class II restorations in primary molars after 1 year. A total of 190 restorations (96 with TPH-Spectrum and 94 with Compoglass) were inserted in 52 children. TPH-Spectrum was applied using the total etching technique, whereas Compoglass was inserted without acid etching prior to application of the bonding adhesive. The restorations were assessed according to the Ryge criteria, directly after placement and after 1 year. After 12 months, 6.4% of the Compoglass and 3.1% of the TPH-Spectrum restorations were clinically unacceptable and had to be renewed. The fillings with Compoglass revealed a tendency to lower evaluation scores with respect to color matching, cavosurface discoloration, anatomic form, margin integrity and caries assessment than the restorations with TPH-Spectrum. However, these differences were statistically not significant. The results of the present investigation show that, at least for a period of 1 year, both the hybrid composite TPH-Spectrum and the polyacid-modified composite resin Compoglass are suitable materials for restoration of deciduous molars. However, owing to the fewer treatment steps required for application of a polyacid-modified composite resin, this type of material may be more favorable for restoring primary molars.
