BACKGROUND AND OBJECTIVE The onset and progression of early tooth decay is often preventable with dental sealants. However, occasionally decay progresses underneath the sealant. Current technology does not permit monitoring of potential lesion progression or arrest. Dental sealants themselves mask the visual cues that identify early tooth decay, and radiographs are not sufficiently sensitive. T...

BACKGROUND In the lumbar spinal column, an annular disruption may be sealed after annulotomy to prevent further prolapse and instability. We investigated the biomechanical effects of various material properties of an injectable sealant. METHODS We used a 3-dimensional, nonlinear, osteoligamentous, experimentally validated finite-element model of the L3-L5 spine segment to study annulotomies o...

Resin-based pit-and-fissure sealants are often used to form a barrier on the occlusal surface of molars to treat caries lesions; however, bacteria can remain in the pit and fissures without detection, increasing the risk of secondary caries. Sealants with antimicrobial properties or microbial repellent actions might be advantageous. The aim of this study was to assess the inhibitory effect of a...

BACKGROUND Sealant application during fixed appliances orthodontic treatment for enamel protection is common, however, reliable data on its durability in vivo are rare. OBJECTIVE This study aims at assessing the durability of a sealant (OpalSeal, Ultradent) for protection against white-spot lesion formation in orthodontic patients over 26 weeks in vivo, taking into account the provision or ab...

OBJECTIVE To evaluate the efficacy of fibrin sealant in reducing resection surface-related complications in liver surgery. BACKGROUND Bile leakage, bleeding, and abscess formation are major resection surface-related complications after liver resection. It is unclear whether application of fibrin sealant to the resection surface is effective in reducing these complications. METHODS In a mult...

The utilization of fibrin sealants to augment hemostasis, seal tissues, and facilitate targeted delivery of drugs is increasing. In 1985, a hospital-based program was established to provide autologous and allogeneic cryoprecipitate that serves as a fibrin sealant when combined with bovine thrombin. To date, more than 4,000 patients have been treated with this product at our institution, with an...
