Objectives: This study tested the fracture resistance of capped and uncapped bulk-fill composite restorations and compared them to a conventional composite. Also, the effect of different radiant exposure was investigated.
Methods And Materials: Flowable and high-viscosity bulk-fill composites (SureFil SDR, Filtek Bulk-Fill Posterior, and Tetric N-Ceram Bulk-Fill) and a nanohybrid resin composite (Filtek Z350 XT) were used.

This study aimed at developing a controlled drug delivery system for recombinant human insulin-like growth factor-I (IGF-I) for localized delivery in bone healing. IGF-I was microencapsulated into an end-group uncapped 14 kDa poly(D,L-lactide-co-glycolide) 50:50 (PLGA 50:50) by solvent extraction from a W(1)/O/W(2) dispersion. Prior to encapsulation, IGF-I was exposed to ultrasonication in a water/dichloromethane dispersion, and its stability tested in the presence and absence of various excipients in the W(1) phase.

A review of all cases of operative hand surgery at The Adelaide Children's Hospital during the period January 1-June 30, 1988 yielded 38 cases that resulted from trauma (burns and fractures excluded). Lacerations from uncapped galvanized-iron fences occurred in 10 patients. Of these patients, two patients required skin grafts, seven patients had flexor-tendon injuries and three patients suffered digital-nerve lacerations.
