A national survey of the impact of the COVID-19 pandemic on training and wellbeing of restorative and mono-speciality specialist trainees in the UK and Ireland.

Introduction COVID-19 emergency and associated measures across the UK and Ireland during the first and third waves of the pandemic disrupted mainstream dental services and training across all specialties.Aims Investigate the effect of COVID-19 pandemic on training, mental health and wellbeing of specialty trainees (STs) in restorative dentistry and associated mono-specialities across the United Kingdom and Ireland.Materials and methods A cross-sectional survey was conducted exploring experiences of STs in restorative dentistry, prosthodontics, endodontics and periodontics (n = 101) across the United Kingdom and Ireland during the first (March 2020) and third (July 2021) waves of the pandemic.

The teaching and assessment of local anaesthesia in UK dental schools.

Introduction: Local anaesthesia (LA) is fundamental to successful dental treatment. Graduating hygienists, therapist and dentists should be confident and proficient in delivering LA. There is one previously published article reviewing LA teaching in United Kingdom (UK) dental schools in 2016, and at this time 10 out of 14 schools allowed peer-to-peer administration.

Denture cleanliness and hygiene: an overview.

Dentures are an excellent treatment modality for partial and edentate patients; however, improper denture care and hygiene can result in both decreased longevity of the prosthesis and increased risk of developing dental caries, periodontal disease and oral candidosis. Previously, it has been shown that patients and dental professionals are unaware of the different materials and methods available for optimum denture care and hygiene. This article provides an overview of the key legislation and main commercially available methods for denture cleanliness and hygiene, and serves as a basis for providing tailored denture hygiene for denture wearers.

Malignant Transformation Rate of Oral Submucous Fibrosis: A Systematic Review and Meta-Analysis.

Oral submucous fibrosis (OSF) is a chronic progressive condition affecting the oral cavity, oropharynx and upper third of the oesophagus. It is a potentially malignant disorder. The authors collated and analysed the existing literature to establish the overall malignant transformation rate (MTR).

Calcium phosphate nanoparticles for potential application as enamel remineralising agent tested on hydroxyapatite discs.

Calcium phosphate exhibits excellent biocompatibility, and with particle size in the nanoscale, calcium phosphate nanoparticles (CPNPs) were explored to replace the hydroxyapatite lost in the nanoporous teeth due to dental erosion. CPNPs (2% w/v) colloidally stabilised by sodium citrate were synthesised co-precipitation. They were characterised in terms of particle size, morphology, crystallinity, Ca/P ratio and calcium ion release.

The synthesis of nano silver-graphene oxide system and its efficacy against endodontic biofilms using a novel tooth model.

Objective: The deleterious caustic effects of sodium hypochlorite (NaOCl) as a root canal irrigant makes it imperative that alternative methods are developed for root canal disinfection. The purpose of this study was to examine the antimicrobial efficacy of silver nanoparticles (AgNPs) synthesized on an aqueous graphene oxide (GO) matrix (Ag-GO), with different irrigant delivery methods to enhance the disinfection regimen, using a novel ex vivo infected tooth model.

Methods: AgNPs were prepared by reducing AgNO with 0.

Detection threshold of non-contacting laser profilometry and influence of thermal variation on characterisation of early surface form and textural changes in natural human enamel.

Objectives: To determine the detection threshold of non-contacting laser profilometry (NCLP) measuring surface form and surface roughness change in natural human enamel in vitro, characterise how ambient scanning thermal variation affects NCLP measurement, and calculate bulk enamel loss in natural human enamel.

Methods: NCLP repeatability and reproducibility accuracy was determined by consecutively scanning natural human enamel samples with/without sample repositioning. Ambient thermal variation and NCLP sensor displacement over short (30 s), medium (20 min), and long (2 h) scanning periods were evaluated for their standard deviation.
