Single‐ or two‐visits endodontic treatment: Impact of irrigants on surface roughness, microhardness, topography, and fracture resistance of root dentin

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the effect of the number of simulated endodontic treatment visits and the type of irrigant on the surface roughness, microhardness, topography, and fracture resistance of root dentin. Bovine roots were distributed into six groups (n = 14) according to the irrigant and number of treatment visits: 0.9% saline solution ...

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Role of adjunctive methacryloyloxydecyl dihydrogen phosphate primers on dentin bond strength of universal adhesives under saliva and artificial aging

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated whether adjunctive 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) primers enhance the microtensile bond strength (µTBS) of two universal adhesives (UAs) to dentin under artificial aging and repeated salivary contamination applied at each bonding step.

Associations Between Multimorbidity, Polypharmacy and Oral Conditions in Older Adults: A Systematic Review and Meta‐Analysis

Gerodontology, EarlyView.
ABSTRACT Objective This systematic review and meta‐analysis evaluated the relationship between multimorbidity and polypharmacy on the oral health in older adults (aged 75 years or older). The PECO focus question set for this study was, ‘What is the occurrence, association and impact of multimorbidity and polypharmacy on the oral conditions and its ...
