Abstract Objective Effective bond strength of composite resin restoration leads to its durability, so evaluation of dentin surface treatment with enzymes and laser for higher bond strength is an important factor. Materials and Methods Sixty human molar teeth were cut at a depth of 2 mm of occlusal part and divided into six groups (n = 10).

We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Abstract Introduction The effectiveness of root canal therapy in endodontic practice is largely determined by providing a compact fluid‐tight closure at the apex of the root canal, which inhibits irritant entry and buildup, which leads to a biological breakdown of the attachment mechanism and failure.

The relationship between form and function of the carnivore mandible
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Expert perspective: How, When, and Why to Potentially Stop Anti‐resorptive Drugs in Osteoporosis
Osteoporosis is a chronic disease and anti‐resorptive treatments are often continued for many years. Despite their established efficacy in reducing fracture risk, the most commonly used anti‐resorptive treatments bisphosphonates and denosumab have short and longer term risks that, coupled with their benefits and other unique characteristics, influence ...

Abstract Objectives To evaluate intermediate treatments between sodium hypochlorite and chlorhexidine gluconate irrigations for the prevention of a toxic brown precipitate in root canal therapy. Materials and Methods Thirty‐nine premolars were irrigated with 6% sodium hypochlorite and divided into either: No intermediate treatment; Dry paper points ...
