High‐Concentration Hydrogen Peroxide Gels Containing Calcium Polyphosphate Associated With Violet Led Light: Bleaching Efficacy and Effects on Enamel Properties

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of violet LED light (VL) and hydrogen peroxide (HP) in‐office bleaching gels supplemented with calcium polyphosphate (CaPP) or calcium gluconate (GU): Materials and Methods Bovine enamel blocks (n = 10) were randomly assigned: commercial HP gel, commercial HP gel with GU, or experimental 35% HP with or without

Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS): fieldwork, synthesis and modelling efforts

open access: yesFrontiers in Marine Science, 2016
The ocean’s biological carbon pump plays a central role in regulating atmospheric CO2 levels. In particular, the depth at which sinking organic carbon is broken down and respired in the mesopelagic zone is critical, with deeper remineralisation resulting

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

Inflammatory and Immunological Basis of Periodontal Diseases

open access: yesJournal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Scaling after remineralisation of reverse osmosis permeate

open access: yesDesalination, 2019
Abstract Scaling problems are more frequently observed in hot water equipment fed with remineralised reverse osmosis permeate compared to hot water systems fed with conventionally purified water. These problems occur when permeate from reserve osmosis is remineralised to a hardness to meet the regulations.

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Inflammation and mechanical force‐induced bone remodeling

open access: yesPeriodontology 2000, EarlyView.
Abstract Periodontitis arises from imbalanced host–microbe interactions, leading to dysbiosis and destructive inflammation. The host's innate and adaptive immune responses produce pro‐inflammatory mediators that stimulate destructive events, which cause loss of alveolar bone and connective tissue attachment.
