Effect of Er:YAG, Co2 lasers, papain, and bromelain enzymes dentin treatment on shear bond strength of composite resin

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1575-1581, December 2022., 2022
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).

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
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 ...

Sealing ability in vitro study and biocompatibility in vivo animal study of different bioceramic based sealers

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1582-1590, December 2022., 2022
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

open access: yesThe Anatomical Record, EarlyView.
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 ...

Effect of preparation design on marginal adaptation and fracture strength of ceramic occlusal veneers: A systematic review

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1391-1403, December 2022., 2022
Abstract Objectives This systematic review aims to investigate the effect of different preparation designs on the marginal fit and fracture strength of ceramic occlusal veneers. Materials and Methods Based on the PICO question and the search terms, an electronic search was performed in Google Scholar, PubMed (MEDLINE), Scopus, Cochrane Library, Web of ...

Expert perspective: How, When, and Why to Potentially Stop Anti‐resorptive Drugs in Osteoporosis

open access: yesArthritis &Rheumatology, Accepted Article.
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 ...

Comparative evaluation of intermediate solutions in prevention of brown precipitate formed from sodium hypochlorite and chlorhexidine gluconate

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1591-1597, December 2022., 2022
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 ...
