ABSTRACT
The in vitro occlusal wear of two recently introduced, small-particle composite resins was evaluated. Twelve disks of each material were opposed by maxillary third molars and subjected to 300,000 masticatory cycles in a servohydraulic model of the human masticatory apparatus. Before and after profiles of the surfaces of both the disks and the teeth were mapped and digitally recorded on magnetic disks. P-50 disks showed significantly (P < .05) less volume loss than did Herculite disks. Enamel that opposed P-50 disks showed significantly (P < .001) more near than did enamel that opposed Herculite disks.

    Background/Aim. Retention of fissure sealants and good adaptation to enamel are essential for their success. Fluoride releasing resin-based materials are widely accepted for pit and fissure sealing, but newly designed glass ionomers can serve as a good alternative. The aim of this study was to...

    A laboratory study was conducted to explore the possibility of imparting an anticariogenic property to the resins used as pit and fissure sealants via the addition of NaF to the materials. The addition of NaF in amounts of 2 to 5% appreciably reduced enamel solubility and increased its fluoride...

    Self-etch bonding systems are promoted as a time-saving and user-friendly alternative to etch-and-rinse bonding systems. Self-etch adhesives are characterized by a relatively mild etching effect, resulting in a relatively low incidence of postoperative hypersensitivity. On the other hand, their...
