Background Dental procedures often produce aerosol and splatter which have the potential to transmit pathogens such as SARS‐CoV‐2. The existing literature is limited. Objective(s) To develop a robust, reliable and valid methodology to evaluate distribution and persistence of dental aerosol and splatter, including the evaluation of clinical procedures. Methods Fluorescein was introduced into the irrigation reservoirs of a high‐speed air‐turbine, ultrasonic scaler and 3‐in‐1 spray, and procedures were performed on a mannequin in triplicate. Filter papers were placed in the immediate environment. The impact of dental suction and assistant presence were also evaluated. Samples were analysed using photographic image analysis, and spectrofluorometric analysis. Descriptive statistics were calculated and Pearson’s correlation for comparison of analytic methods. Results All procedures were aerosol and splatter generating. Contamination was highest closest to the source, remaining high to 1–1.5 m. Contamination was detectable at the maximum distance measured (4 m) for high‐speed air‐turbine with maximum relative fluorescence units (RFU) being: 46,091 at 0.5 m, 3,541 at 1.0 m, and 1,695 at 4 m. There was uneven spatial distribution with highest levels of contamination opposite the operator. Very low levels of contamination (≤0.1% of original) were detected at 30 and 60 minutes post procedure. Suction reduced contamination by 67–75% at 0.5–1.5 m. Mannequin and operator were heavily contaminated. The two analytic methods showed good correlation ( r =0.930, n =244, p <0.001). Conclusion Dental procedures have potential to deposit aerosol and splatter at some distance from the source, being effectively cleared by 30 minutes in our setting.
Toothbrushing programmes The BDA has backed new calls from NICE for oral health programmes in schools, calling on national government to support local authorities to turn the tide on an epidemic of tooth decay. NICE has recommended councils provide toothbrushing schemes in schools and nurseries in areas where children have poor oral health. Similar schemes exist in both Wales and Scotland, where devolved governments have set out dedicated oral health strategies that include outreach to early years and primary schools, and which have contributed to record breaking falls in decay. Despite progress by many local authorities , there is no equivalent programme in England. Health officials have claimed that devolution of powers to local authorities in England represents a barrier to rolling out a dedicated national programme.

A summary is given of how urgent dental care was established in the North East of England during the COVID-19 pandemic, which may help with future preparedness for pandemics.Aerosol generating procedures were almost always avoided in the delivery of urgent dental care. A telephone triage system was effectively used to determine who needed clinical care and to separate symptomatic, asymptomatic and shielding patients, with very few failures in triage noted.
One-third of the population will only attend the dentist for an acute problem, often waiting a period of time before presenting. The objective of this study was to investigate the levels of pain in patients presenting for a dental emergency and the impact this had on their quality of life. Questionnaires were provided to adult patients attending dental emergency services over 1 week. Demographic and clinical details were collected. Quality of life was measured using EQ-5D-5L. Pain and the interference it caused were examined using the graded chronic pain scale. Data were analysed in STATA using descriptive statistics, Mann-Whitney and chi-squared tests. Results showed that majority of patients (64%) seen were male; the mean age was 36 (±14) years. Forty six per cent of patients reported having a general dental practitioner. One-third of the patients had attended this service previously for emergency care, and 13% consulted for the same problem. The mean duration of pain was 17·7 (±52·3) days prior to seeking care. The mean characteristic pain intensity was 53·6 (±23·6). The mean disability score was 43·4 (±33·6). The mean EQ-5D-5L score was 0·57 (±0·27). In conclusion, a large number of patients attend the emergency dental services despite being 'registered' with a general dental practitioner. A proportion of these individuals will re-attend for the same condition. Patients will often be in pain for over 2 weeks before attending, which may have a significant impact on their quality of life. Further research is warranted to investigate these care-seeking behaviours and patterns.
Objective To develop a beta version of a preliminary set of empirically derived research diagnostic criteria (RDC) for burning mouth syndrome (BMS) through expert consensus, which can then be taken into a test period before publication of a final RDC/BMS. Design A 6 round Delphi process with twelve experts in the field of BMS was used. The first round formed a focus group during which the purpose of the RDC and the definition of BMS was agreed upon, as well as the structure and contents. The remaining rounds were carried out virtually via email to achieve a consensus of the beta version of the RDC/BMS. Results The definition of BMS was agreed to be ‘an intraoral burning or dysaesthetic sensation, recurring daily for more than 2 hours per day over more than 3 months, without evident causative lesions on clinical examination and investigation’. The RDC was based upon the already developed and validated RDC/TMD and formed three main parts: patient self‐report; examination; and psychosocial self‐report. A fourth additional part was also developed listing aspirational biomarkers which could be used as part of the BMS diagnosis where available, or to inform future research. Conclusion This Delphi process has created a beta version of an RDC for use with BMS. This will allow future clinical research within BMS to be carried out to a higher standard, ensuring only patients with true BMS are included. Further validation studies will be required alongside refinement of the RDC as trialling progresses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
