Clinical Evaluation of Tooth-colored Materials in Small Class I Lesions

Tooth-colored adhesive materials have been increasingly used after the introduction of minimal intervention concept. Objective: The present study aimed to evaluate clinical performances of tooth-colored adhesive materials restored in small class I lesions. Method: The materials were Fuji II LC capsule (FII), Fuji IX capsule (FIX), Filtek Supreme/Clearfil Photo Bond (S/C), Filtek Supreme/Prime&Bond NT (S/P).  All materials were randomly restored on 122 class I lesions of posterior teeth under rubber dam. The restorations were restored by 2 operators following the manufacturers' instructions. They were evaluated by 2 evaluators at base line and 18 months. The assessments were based on modified Ryge's criteria. The criteria were color match (CM), retention (RT), marginal discoloration (MD), marginal adaptation (MA), secondary caries (SC), anatomic form (AF) and surface texture (ST). Result: The results (% alpha grade) are summarized in the table. Conclusion: Within 18 months, glass-ionomer restorations exhibited comparable performances to composite except for their color match and surface texture.
