title: [P-30: in vivo study of a posterior composite during 2.5 years].
abstract: P-30, a light-cured radioopaque hybrid composite was developed as a successor to the well known chemically cured P-10 for use as posterior composite. With the help of a computerized measuring method the occlusal wear of occlusally loaded conventional P-30 MOD restorations was analyzed after 6, 12, 18 and 30 months of clinical service. Simultaneously the wear patterns in occlusal contact areas and in contact-free areas were evaluated using the SEM. In addition, marginal adaptation immediately after the placement of the restorations and at all recall intervals was quantitated in the SEM. The long-term results indicated that P-30 was not suitable for use in unetched conventional posterior cavities.
