Shear bond strength of composite resin to fresh amalgam.

The shear bond strength between fresh amalgam and composite resin using three adhesive systems was assessed. Amalgambond (5.19 MPa), All-Bond (3.45 MPa), and Clearfil New-Bond (4.37 MPa) had comparable shear bond strengths higher than Enamel Bond (1.27 MPa) after 48 hours of water immersion. This bond was hydrolytically degraded during 100 days of immersion in water. The greatest deterioration was observed for Clearfil New-Bond (0.81 MPa). Amalgambond provided the best results, whereas All-Bond and Clearfil New-Bond had comparable bond strength to Enamel Bond at the end of the experiment.

Papilla regeneration by noninvasive prosthodontic treatment: segmental proximal restorations.

Bonded segmental proximal restorations, whether direct or laboratory fabricated, can be added to selected aspects of a tooth utilizing the acid-etch technique with no macromechanical preparation. When properly executed the prosthetic supplements guide and support newly regenerated papillae in deficient interproximal aspects. Although they are overcontoured, the properly finished and polished convex intracrevicular areas of the restorations will not have adverse effects on the tissues. When overcontoured restorations are limited in the interproximal space, compression and relief of the gingival fibers results. Alternately, any overcontouring of the labial aspects might stretch and cause overtension to the gingival fibers and result in iatrogenic damage to the periodontal support structures. The controlled, intentional, overcontoured proximal restorations and the adjoining soft tissues can easily be maintained through regular oral hygiene measures, for healthy, long-lasting service.
