A clinical evaluation of packable and microhybrid resin composite restorations: one-year report.
OBJECTIVE
The objective of this study was to evaluate the clinical performance of two packable and one microhybrid resin composites placed in occlusal cavities of posterior permanent teeth after 1 year.


METHODS
Sixty occlusal restorations were placed in 18 male or female patients aged 21 to 44 years. The restorations were divided into three groups according to the restorative material: G1 (Surefil + Prime&Bond NT); G2 (Filtek P60 + Singlebond), and G3 (Suprafill + Suprafill). They were placed by two previously calibrated operators. The restorations were directly evaluated for color matching, marginal discoloration, secondary caries, wear, marginal adaptation, and postoperative sensitivity.


RESULTS
Of the total restorations, 66.7% were scored A (ideal) for color matching; 98.2% for marginal discoloration; 100% for secondary caries; 92.6% for wear; and 92.6% for marginal adaptation. Postoperative sensitivity was reported in 5% of the restorations. Fisher's exact, McNamara's, and chi-square tests did not indicate statistical difference between the groups, related to the evaluated criteria.


CONCLUSIONS
The packable (Filtek P60 and Surefil) and the microhybrid (Suprafill) resin composites exhibited excellent clinical performance after 1 year and may be considered possible materials for the restoration of posterior teeth.
