Clinical performance of class I occlusal composite resin restorations: a multicenter double-blinded randomized clinical trial

Abstract

<p><strong>Objective: </strong>The objective of this study was to evaluate the 6-month clinical performance of class I occlusal composite resin restorations through a multicenter, randomized, double-blind, clinical trial. <strong>Material e Métodos: </strong>Two hundred and eighty class I occlusal restorations were performed in 70 patients (aged between 17 to 50 years). The restorations were divided into four groups: G1 (Filtek P60/3M ESPE); G2 (Rok/SDI); G3 (Filtek™ P90/3M ESPE); G4 (Evolux/Dentsply). Two pre-calibrated dental practitioners performed and evaluated the restorative procedures regarding to color match, marginal discoloration, recurrent caries, wear (anatomic form) and marginal integrity according to the USPHS criteria. <strong>Resultados: </strong>In 85.8% of the evaluated restorations was observed the ideal score (A) for color match; 91.4% for marginal discoloration; 100% for recurrent caries; 87.7% for wear (anatomic form) and 99.3% for marginal integrity.<strong> Conclusion: </strong>The composite resins used in this study presented satisfactory and similar clinical performance in a 6-month clinical evaluation.</p><p><strong>Keywords</strong></p><p>Dentistry; Composite resins; Permanent dental restoration; Molar; Bicuspid.</p>

Clinical Evaluation of Postoperative Sensitivity in Class I Resin Composite Restorations

“…Eighty Class I restorations were performed in molars and premolars of sixteen male (n=5) and female patients (n=11), aged between 23 and 46 years, of the CISAM. Sample size was calculated according to previous studies [13,17,18]. The restorations were divided into four groups according to adhesive system and the resin composite used (Figure 1).…”
