Novel nitro‐quinoline photoinitiators for composites: exploring the effects of hydroxyl and methacrylate substituents on the photopolymerization of dimethacrylate matrices

open access: yesPolymer International, EarlyView.
New quinoline derivatives proved to be efficient photoinitiators for dental resin monomers under two different light‐curing units, yielding favorable conversion, color and fluorescence results in the presence of different co‐initiators, including an eco‐friendly alternative.

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

open access: yesHigh Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Effect of root canal irrigants on the bond strength between resin sealants and dentin

open access: yes口腔疾病防治, 2019
When the root canal is filled, the use of the adhesive resin⁃based sealant to form a strong bond with the dentin reduces microleakage of the apex, enhances the bending resistance of the tooth, and resists the mechanical dam⁃ age of the pile preparation,

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

open access: yesAustralian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

open access: yesBoreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Cytotoxic Interactive Effects of Dentin Bonding Components on Mouse Fibroblasts [PDF]

open access: yes, 1995
Previous studies have shown a wide range of pulpal reactions to dentin bonding systems and a poor correlation between in vitro and in vivo toxicity of dentin bonding agents.

Influence of rubbing during etching on surface roughness and interfacial characteristics of intact enamel

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...
