Process evaluation of a pragmatic feasibility trial on smokeless tobacco cessation intervention delivered in dental hospitals.

BACKGROUND: Article 14 of the WHO 'Framework Convention on Tobacco Control' recommends, that all oral healthcare providers provide support for tobacco cessation, to all patients. Despite evidence on the effectiveness of tobacco cessation interventions in dental settings, implementation remains low in most high-burden countries like Pakistan. A pragmatic pilot trial of a dentist-delivered behavioural support intervention for smokeless tobacco (ST) cessation, was conducted in dental hospitals in Pakistan. This paper presents the findings of the process evaluation of the trial. METHODS: A mixed-method process evaluation of a multi-centre randomised control pilot trial of dentist-delivered behavioural support intervention ST cessation was conducted. The intervention included three sessions namely: pre-quit, quit and post-quit sessions. The process evaluation involved: semi-structured interviews with trial participants (n = 26, of which dental patients were n = 13 and participating dentists were n = 13 conducted from June-August 2022); and fidelity assessment of audio recordings of the intervention sessions (n = 29). The framework approach was used to thematically analyse the interview data. RESULTS: Overall the trial procedures were well accepted, however, young patients expressed uneasiness over revealing their ST use status. The intervention was received positively by dentists and patients. Dentists identified some challenges in delivering behavioural support to their patients. Of these, some were related to the contents of the intervention whereas, others were related to the logistics of delivering the intervention in a clinical setting (such as workload and space). Acceptability of the intervention resources was overall low amongst young patients as they did not take the intervention resources home due to fear of their family members finding out about their ST use. The intervention was successful in achieving the intended impact (in those who engaged with the intervention), i.e., change in the patients' ST use behaviour. Giving up ST with the aid of behavioural support also had an unintended negative effect i.e., the use of harmful substances (cannabis, cigarettes) to give up ST use. Patients' satisfaction with their dental treatment seemed to influence the intervention outcome. CONCLUSION: While there are many variables to consider, but for the participants of this study, behavioural support for abstinence delivered through dentists during routine dental care, appears to be an acceptable and practical approach in helping patients give up ST use, in a country like Pakistan, where negligible support is offered to ST users.

Smokeless Tobacco Cessation Support in Dental Hospitals in Pakistan: Dentists and Dental Patients' Perspectives on Current Practices, Support Needed, and Opportunities Available.

INTRODUCTION: Despite evidence on the effectiveness of tobacco cessation interventions in dental settings, the implementation remains low, especially for smokeless tobacco (ST). The purpose of this study was to develop an understanding of the influences governing the implementation of ST cessation support in dental hospitals. AIMS AND METHODS: A multicenter qualitative study was conducted at two tertiary-care dental hospitals, in Pakistan. Semi-structured interview guide, guided by the Capability-Opportunity-Motivation-Behavior (COM-B) model, were used to capture the views of dentists (n = 12) and dental patients (n = 12), regarding ST cessation support in dental hospitals. Framework approach was used to thematically analyze the data. RESULTS: Screening of ST users in routine dental practice was seldom practiced and the cessation support offered was brief advice. Barriers identified by dentists included: Fear of offending and stereotyping patients; lack of knowledge and skills; lack of privacy; lack of belief in the effectiveness of behavioral support; lack of time and workload pressure; ST use amongst dentists; lack of referral systems and; the absence of a mandatory requirement of offering ST cessation support. Facilitators included: Delivering support through junior dentists and the length of interaction between the dentist and the patient. Naswar was the most common ST product used by dental patients. Patients reported receiving negligible cessation support from any healthcare provider. CONCLUSIONS: A range of influences governing the implementation of ST cessation support in dental hospitals were identified. These findings can inform the implementation of behavioral interventions for ST cessation in dental and other clinical settings, in low and middle-income countries. IMPLICATIONS: Smokeless tobacco control considerably lags, in comparison to the control of combustible tobacco. This is the first study that qualitatively explores the implementation of ST cessation support in dental settings in Pakistan. Utilizing the "Capability-Opportunity-Motivation-Behavior" model, it provides an in-depth understanding of the inability of dentists in implementing effective behavioral interventions for ST cessation support in routine dental practice. Highlighting the striking discrepancy between the patient's need for and receptivity towards cessation support and the dentists' concerns over their patients' receptivity towards cessation support, it calls for the need for effective implementation strategies to optimize dentist-led tobacco cessation interventions in low-resource settings.

Behaviour Change Intervention for Smokeless Tobacco (ST) Cessation Delivered through Dentists in Dental Settings: A pragmatic pilot trial.

INTRODUCTION: Evidence on smokeless tobacco (ST) cessation interventions is scarce. The South Asian (SA) region which shares more than 90% of the burden of ST use, is grossly underrepresented in research on ST cessation. This study aimed to assess the feasibility of delivering and investigating a behavioural support intervention for ST cessation in dental settings in Pakistan. METHODS: A multi-centre, pilot, 2-armed parallel group, individually randomised control trial, with a 1:1 allocation ratio, was conducted at two dental hospitals. Eligibility criteria included: being a ST user; seeking dental treatment and; not currently accessing cessation support. All participants were provided written self-help, ST cessation material. The intervention group also received a dentist-delivered, bespoke behavioural support intervention for ST cessation developed for users of SA origin. Participants were followed up telephonically at three and six months. Self-reported six month abstinence was verified by salivary cotinine. Analysis was descriptive, with 95% confidence intervals presented where appropriate. RESULTS: 100 participants were successfully recruited from the selected hospitals. Of these 78% continued to engage throughout the study duration and provided primary outcome data, whereas, 63% completed all hospital visits. The outcome measures were successfully collected. Biochemically verified six-month abstinence in the intervention and control group was 10% and 4%. CONCLUSIONS: It was feasible to deliver and evaluate a dentist-delivered behavioural support intervention for ST cessation in Pakistan. The data suggested that the intervention may improve ST quit rates. The findings of this study will be useful in informing the design of future definitive studies. IMPLICATIONS: To our knowledge this is the first pragmatic pilot trial on ST cessation in dental settings in Pakistan and the first trial on dentist-delivered structured behavioural support intervention for ST cessation. It adds to the scarce, trial evidence base on ST cessation interventions. Findings suggest behavioural support intervention for ST cessation may improve quit rates. The trial was conducted in a country with poor ST control measures, where ST products are not taxed, the products are sold openly to and by minors and the users are offered negligible cessation support. The findings may therefore be generalisable to LMICs and particularly South Asian countries, with similar policy backgrounds.

Nicotine pouches: a review for the dental team.

Nicotine pouches are tobacco-free products that are becoming increasingly popular in the UK. They are held between the user's lip and gum to provide a source of nicotine. This article describes the composition of nicotine pouches, the legality surrounding their production and sale, patterns of use and explores possible oral and general health effects of their usage.

Effect of tobacco and nicotine in causing staining of dental hard tissues and dental materials: A systematic review and meta-analysis.

INTRODUCTION: Dental staining is a common concern for tobacco users. However, little is known about which components of tobacco are responsible for the staining and whether nicotine may be implicated. This is of increasing relevance with the popularity of novel products such as heated-tobacco products and electronic cigarettes (E-cigarettes). OBJECTIVES: This systematic review aimed to establish the evidence base for the effect if any, of the various tobacco and nicotine products in causing staining of dental hard tissues and materials. MATERIAL AND METHODS: This systematic review was performed in accordance with the preferred reporting items for systematic reviews and meta-analyses guidelines. There were four structured population intervention comparison outcomesquestions. A search was conducted up to December 2021 in three databases: MEDLINE, EMBASE, and Web of Science, and manual searching of relevant sources was also completed. Two researchers individually reviewed the titles then abstracts and finally full articles. A reporting quality appraisal was conducted appropriately to the study methodology. RESULTS: Of the 815 records titles identified, 56 full-text articles were assessed for eligibility, of which 27 were included for analysis. The included studies were mainly laboratory studies of varying reporting quality. There was evidence from 18 studies that tobacco exposure caused staining of dental hard tissues (pooled results from three studies- enamel/dentine; mean difference [MD]: 16.22; 95% confidence interval[12.11, 20.32; I2 : 96%)and materials (pooled result from four studies-resin composite; MD: 11.90; 95% CI: 11.47, 12.34; I2 : 100%). There was limited evidence that E-cigarettes 99%) and heated tobacco products (HTPs; pooled results from three studies--1.07, 6.54; I2 : 99%) cause staining, but this was lower than with traditional tobacco/found 11 compounds, of which 8 were terpenoids, from tobacco products implicated in causing staining. Finally, there was some evidence that resin composites stained more than other materials. CONCLUSIONS: Tobacco smoking causes dental staining. There was limited evidence that E-cigarettes and HTPs did cause dental staining that was less intense than that caused by traditional tobacco products.

Monkeypox: what do dental professionals need to know?

Infection control is critical for the safe delivery of dental care. Infection control practices must be responsive to emerging and re-emerging infectious diseases and outbreaks, as was clearly seen during the peak of the COVID-19 pandemic. An emerging global outbreak of the monkeypox virus has again raised potential challenges for infection control in dentistry. Monkeypox is an infectious disease, characterised by a rash affecting the skin and soft tissues, including the oral cavity. Previously, cases were mostly seen following contact with infected animals in Central and West Africa, with limited human-to-human transmission within and outside of these areas. However, since May 2022, sustained human-to-human transmission has occurred globally. Monkeypox can be transmitted via close contact with an infected person, contaminated objects and surfaces, or by droplets and possibly aerosols, which is therefore of potential importance to dental settings. This article discusses the relevance of monkeypox to dental professionals, the typical presentation of the disease, its potential impact on infection prevention and control practices and the delivery of dental services. The current monkeypox outbreak highlights the need for a more sustained programme of research into dental infection control that can provide a solid evidence base to underpin preparedness planning for future outbreaks and pandemics.

Behaviour change intervention for smokeless tobacco (ST) cessation delivered through dentists within a dental setting: a feasibility study protocol.

OBJECTIVES/AIM: To adapt a structured behavioural support intervention for smokeless tobacco (ST) cessation and to assess the feasibility and acceptability of delivering the intervention via dentists within dental settings in Pakistan. MATERIAL AND METHODS: The study will have 3 phases: (1) Adapt a previously developed intervention to make it suitable for delivery in a clinical/dental setting through qualitative interviews with dental patients and dentists; (2) A multi-centre, pilot randomised control trial in two teaching dental hospitals in Pakistan. Participants (dental patients) will be randomly assigned to intervention or control group in a 1:1 allocation ratio to receive either a structured behavioural support intervention involving face to face counselling or self-help material plus usual care. Each participant will be in the study for approximately 6 months and the overall study is expected to run for 12 months; (3) An embedded qualitative process evaluation. All trial participants will be followed up at 3 and 6 months to assess self-reported ST use. Outcome measures will include: rates of eligibility, recruitment and retention, randomisation group cross-over rates, the provision of data on ST use behaviour, fidelity to the intervention and qualitative assessment of acceptability and feasibility. DISCUSSION: Despite the high use of ST in Pakistan, users are offered negligible cessation support. The findings of this multi-centre, mixed-method feasibility study will inform the scope for a larger trial on ST cessation delivered through the existing dental health system.

General dental practitioner views on the current and future provision of advanced NHS restorative dentistry services: a cross-sectional survey in England.

Introduction Advanced NHS restorative dentistry services are an important aspect of patient care. Managed clinical networks (MCNs) have been proposed as a future model of care.Aim To assess general dental practitioners' (GDPs') satisfaction with the current provision of advanced NHS restorative dentistry services and assess their views on MCNs.Methods A self-administered, online survey was distributed by the Northern Dental Practice Based Research Network and was shared on social media.Results In total, 108 responses were received from GDPs working in England; 55% in the North East. GDPs felt current services for periodontics, endodontics, tooth surface loss and temporomandibular disorders were the most important and were most unsatisfied with periodontics, endodontics and tooth surface loss. The most important barriers to current referral practice were previous referral rejections and the return of costly treatment plans. Opinions were favourable towards the proposed MCNs, with one-third of participants feeling they were already suitable to apply to deliver Level 2 services. There was a notable imbalance between sexes, with fewer female dentists (57%) registering interest in joining an MCN compared to their male counterparts (76%) and female dentists also identifying more barriers to join MCNs, including access to suitable training. Recent graduates were least likely to cite a lack of time as a barrier to engaging with MCNs.Conclusions GDPs are currently unsatisfied with advanced NHS restorative dentistry services but appear keen to engage with MCNs. The survey identified important insights which may help healthcare planners develop services.

Oral and periodontal implications of tobacco and nicotine products.

Tobacco use contributes to more mortality and morbidity globally than any other behavioral risk factor. Adverse effects do not spare the oral cavity, with many oral diseases more common, and treatments less successful, in the tobacco-using patient. Many of the oral health effects of cigarette smoking are well established, but other forms of tobacco, including cigars and smokeless tobacco, merit dental professionals' attention. Recently, an expanding variety of new or emerging tobacco and/or nicotine products has been brought to market, most prominently electronic cigarettes, but also including heated tobacco and other noncombustible nicotine products. The use of cannabis (marijuana) is increasing and also has risks for oral health and dental treatment. For the practicing periodontist, and all dental professionals, providing sound patient recommendations requires knowledge of the general and oral health implications associated with this wide range of tobacco and nicotine products and cannabis. This review provides an overview of selected tobacco and nicotine products with an emphasis on their implications for periodontal disease risk and clinical management. Also presented are strategies for tobacco use counselling and cessation support that dental professionals can implement in practice.

The effect of high-speed dental handpiece coolant delivery and design on aerosol and droplet production.

OBJECTIVES: High-speed dental instruments produce aerosol and droplets. The objective of this study was to evaluate aerosol and droplet production from a novel electric micromotor handpiece (without compressed air coolant) in real world clinical settings. METHODS: 10-minute upper incisor crown preparations were performed in triplicate in an open-plan clinic with mechanical ventilation providing 3.45 air changes per hour. A 1:5 ratio electric micromotor handpiece which allows water coolant without compressed air (Ti-Max Z95L, NSK) was used at three speeds: 60,000 (60 K), 120,000 (120 K), and 200,000 (200 K) revolutions per minute. Coolant solutions contained fluorescein sodium as a tracer (2.65 mmol L - 1). High-speed air-turbine positive control, and negative control conditions were conducted. Aerosol production was evaluated at 3 locations (0.5 m, 1.5 m, and 1.7 m) using: (1) an optical particle counter (OPC; 3016-IAQ, Lighthouse) to detect all aerosol; and (2) a liquid cyclone air sampler (BioSampler, SKC Ltd.) to detect aerosolised fluorescein, which was quantified by spectrofluorometric analysis. Settled droplets were detected by spectrofluorometric analysis of filter papers placed onto a rig across the open-plan clinic. RESULTS: Local (within treatment bay) settled droplet contamination was elevated above negative control for all conditions, with no difference between conditions. Settled droplet contamination was not detected above negative controls outside the treatment bay for any condition. Aerosol detection at 1.5 m and 1.7 m, was only increased for the air-turbine positive control condition. At 0.5 m, aerosol levels were highly elevated for the air-turbine, minimally elevated for 200 K and 120 K, and not elevated for 60 K. CONCLUSIONS: Electric micromotor handpieces which use water-jet coolant alone without compressed air produce localised (within treatment bay) droplet contamination, but are unlikely to produce aerosol contamination beyond the immediate treatment area (1.5 m), allowing them to be used safely in most open-plan clinic settings.

No benefit of an adjunctive phototherapy protocol in treatment of periodontitis: A split-mouth randomized controlled trial.

AIM: To assess the efficacy of a commercially available adjunctive phototherapy protocol ("Perio-1") in treatment of periodontitis. MATERIALS AND METHODS: In an examiner-blind, randomized, controlled, split-mouth, multicentre study, 60 periodontitis patients received root surface debridement (RSD) in sextants either alone (control sextants) or with the adjunctive phototherapy protocol (test sextants). Re-evaluation was performed at 6, 12 and 24 weeks. RESULTS: No statistically significant differences in mean (± standard deviation) clinical attachment level (CAL) change from baseline to week 24 were observed between test (-1.00 ± 1.16 mm) and control sextants (-0.87 ± 0.79 mm) at sites with probing pocket depths (PPDs) ≥5 mm ("deep sites") at baseline (p = .212). Comparisons between test and control sextants for all other parameters (CAL change at all sites, PPD change at deep sites/all sites, bleeding on probing, plaque scores), and for all change intervals, failed to identify any statistically significant differences. CONCLUSIONS: The phototherapy protocol did not provide any additional clinical benefits over those achieved by RSD alone. (German Clinical Trials Register DRKS00011229).

Interventions for tobacco cessation delivered by dental professionals.

BACKGROUND: Dental professionals are well placed to help their patients stop using tobacco products. Large proportions of the population visit the dentist regularly. In addition, the adverse effects of tobacco use on oral health provide a context that dental professionals can use to motivate a quit attempt. OBJECTIVES: To assess the effectiveness, adverse events and oral health effects of tobacco cessation interventions offered by dental professionals. SEARCH METHODS: We searched the Cochrane Tobacco Addiction Group's Specialised Register up to February 2020. SELECTION CRITERIA: We included randomised and quasi-randomised clinical trials assessing tobacco cessation interventions conducted by dental professionals in the dental practice or community setting, with at least six months of follow-up. DATA COLLECTION AND ANALYSIS: Two review authors independently reviewed abstracts for potential inclusion and extracted data from included trials. We resolved disagreements by consensus. The primary outcome was abstinence from all tobacco use (e.g. cigarettes, smokeless tobacco) at the longest follow-up, using the strictest definition of abstinence reported. Individual study effects and pooled effects were summarised as risk ratios (RR) and 95% confidence intervals (CI), using Mantel-Haenszel random-effects models to combine studies where appropriate. We assessed statistical heterogeneity with the I2 statistic. We summarised secondary outcomes narratively. MAIN RESULTS: Twenty clinical trials involving 14,897 participants met the criteria for inclusion in this review. Sixteen studies assessed the effectiveness of interventions for tobacco-use cessation in dental clinics and four assessed this in community (school or college) settings. Five studies included only smokeless tobacco users, and the remaining studies included either smoked tobacco users only, or a combination of both smoked and smokeless tobacco users. All studies employed behavioural interventions, with four offering nicotine treatment (nicotine replacement therapy (NRT) or e-cigarettes) as part of the intervention. We judged three studies to be at low risk of bias, one to be at unclear risk of bias, and the remaining 16 studies to be at high risk of bias. Compared with usual care, brief advice, very brief advice, or less active treatment, we found very low-certainty evidence of benefit from behavioural support provided by dental professionals, comprising either one session (RR 1.86, 95% CI 1.01 to 3.41; I2 = 66%; four studies, n = 6328), or more than one session (RR 1.90, 95% CI 1.17 to 3.11; I2 = 61%; seven studies, n = 2639), on abstinence from tobacco use at least six months from baseline. We found moderate-certainty evidence of benefit from behavioural interventions provided by dental professionals combined with the provision of NRT or e-cigarettes, compared with no intervention, usual care, brief, or very brief advice only (RR 2.76, 95% CI 1.58 to 4.82; I2 = 0%; four studies, n = 1221). We did not detect a benefit from multiple-session behavioural support provided by dental professionals delivered in a high school or college, instead of a dental setting (RR 1.51, 95% CI 0.86 to 2.65; I2 = 83%; three studies, n = 1020; very low-certainty evidence). Only one study reported adverse events or oral health outcomes, making it difficult to draw any conclusions. AUTHORS' CONCLUSIONS: There is very low-certainty evidence that quit rates increase when dental professionals offer behavioural support to promote tobacco cessation. There is moderate-certainty evidence that tobacco abstinence rates increase in cigarette smokers if dental professionals offer behavioural support combined with pharmacotherapy. Further evidence is required to be certain of the size of the benefit and whether adding pharmacological interventions is more effective than behavioural support alone. Future studies should use biochemical validation of abstinence so as to preclude the risk of detection bias. There is insufficient evidence on whether these interventions lead to adverse effects, but no reasons to suspect that these effects would be specific to interventions delivered by dental professionals. There was insufficient evidence that interventions affected oral health.

Evaluating splatter and settled aerosol during orthodontic debonding: implications for the COVID-19 pandemic.

Introduction Dental procedures produce splatter and aerosol which have potential to spread pathogens such as SARS-CoV-2. Mixed evidence exists on the aerosol-generating potential of orthodontic procedures. The aim of this study was to evaluate splatter and/or settled aerosol contamination during orthodontic debonding.Material and methods Fluorescein dye was introduced into the oral cavity of a mannequin. Orthodontic debonding was undertaken with surrounding samples collected. Composite bonding cement was removed using a speed-increasing handpiece with dental suction. A positive control condition included a water-cooled, high-speed air-turbine crown preparation. Samples were analysed using digital image analysis and spectrofluorometric analysis.Results Contamination across the eight-metre experimental rig was 3% of the positive control on spectrofluorometric analysis and 0% on image analysis. Contamination of the operator, assistant and mannequin was 8%, 25% and 28% of the positive control, respectively.Discussion Splatter and settled aerosol from orthodontic debonding is distributed mainly within the immediate locality of the mannequin. Widespread contamination was not observed.Conclusions Orthodontic debonding is unlikely to produce widespread contamination via splatter and settled aerosol, but localised contamination is likely. This highlights the importance of personal protective equipment for the operator, assistant and patient. Further work is required to examine suspended aerosol.

Evaluating contaminated dental aerosol and splatter in an open plan clinic environment: Implications for the COVID-19 pandemic.

OBJECTIVES: Identify splatter/aerosol distribution from dental procedures in an open plan clinic and explore aerosol settling time after dental procedures. METHODS: In two experimental designs using simulated dental procedures on a mannequin, fluorescein dye was introduced: (1) into the irrigation system of an air-turbine handpiece; (2) into the mannequin's mouth. Filter papers were placed in an open plan clinic to collect fluorescein. An 8-metre diameter rig was used to investigate aerosol settling time. Analysis was by fluorescence photography and spectrofluorometry. RESULTS: Contamination distribution varied across the clinic depending on conditions. Unmitigated procedures have the potential to deposit contamination at large distances. Medium volume dental suction (159 L/min air) reduced contamination in the procedural bay by 53%, and in other areas by 81-83%. Low volume suction (40 L/min air) was similar. Cross-ventilation reduced contamination in adjacent and distant areas by 80-89%. In the most realistic model (fluorescein in mouth, medium volume suction), samples in distant bays (≥5 m head-to-head chair distance) gave very low or zero readings (< 0.0016% of the fluorescein used during the procedure). Almost all (99.99%) of the splatter detected was retained within the procedural bay/walkway. After 10 min, very little additional aerosol settled. CONCLUSIONS: Cross-infection risk from dental procedures in an open plan clinic appears small when bays are ≥ 5 m apart. Dilution effects from instrument water spray were observed, and dental suction is of benefit. Most settled aerosol is detected within 10 min indicating environmental cleaning may be appropriate after this. CLINICAL SIGNIFICANCE: Aerosols produced by dental procedures have the potential to contaminate distant sites and the majority of settled aerosol is detectable after 10 min. Dental suction and ventilation have a substantial beneficial effect. Contamination is likely to be minimal in open plan clinics at distances of 5 m or more.

Evaluating aerosol and splatter following dental procedures: Addressing new challenges for oral health care and rehabilitation.

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 < .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.

Exploring the use of mouth guards in Muay Thai: a questionnaire survey.

OBJECTIVE: To identify Muay Thai participants' attitudes towards use of mouth guards and their experiences of dental trauma. MATERIALS AND METHODS: An online cross-sectional survey was used to record Muay Thai participants' experiences and opinions regarding use of mouth guards. Participants were recruited from a Muay Thai gym in the north east of England. RESULTS: 92 respondents took part in the survey. 3% reported having never worn a mouth guard, whereas 61% reported routinely wearing mouth guards during a fight. Significantly more (73%) younger participants (18-29 years) reported wearing mouth guards during fights compared to those aged 30 years and older (50%) (p < 0.05). Mouth-formed ('boil and bite') were the most frequently used type of mouth guard (60% of users), followed by custom-made mouth guards provided by a dentist (32%). Factors such as protection, breathing, good fit and comfort were all considered important in the choice of mouth guard. 14% of respondents had experienced dental injuries, with chipped/broken teeth being the most common. CONCLUSION: Given the risk for dental trauma in Muay Thai, it is important that participants are advised regarding mouth guard use, particularly those that do not routinely wear them.

The first six weeks - setting up a UK urgent dental care centre during the COVID-19 pandemic.

Introduction The COVID-19 pandemic has posed many challenges, including provision of urgent dental care. This paper presents a prospective service evaluation during establishment of urgent dental care in the North East of England over a six-week period.Aim To monitor patient volumes, demographics and outcomes at the North East urgent dental care centre and confirm appropriate care pathways.Main outcome methods Data were collected on key characteristics of patients accessing urgent care from 23 March to 3 May 2020. Analysis was with descriptive statistics.Results There were 1,746 patient triages (1,595 telephone and 151 face-to-face), resulting in 1,322 clinical consultations. The most common diagnoses were symptomatic irreversible pulpitis or apical periodontitis. Sixty-five percent of clinical consultations resulted in extractions and 0.8% in an aerosol generating procedure. Patients travelled 25 km on average to access care; however, this reduced as more urgent care centres were established. The majority of patients were asymptomatic of COVID-19 and, to our knowledge, no staff acquired infection due to occupational exposure.Conclusion The urgent dental care centre effectively managed urgent and emergency dental care, with appropriate patient pathways established over the six-week period. Dental preparedness for future pandemic crises could be improved and informed by this data.

Perceived influences on smoking behaviour and perceptions of dentist-delivered smoking cessation advice: A qualitative interview study.

OBJECTIVES: Many factors lead to the commencement and maintenance of smoking, and better understanding of these is relevant in the management of oral health, particularly as smoking cessation advice (SCA) from the dental team is a key component of patient care. Whereas most previous research has focused on dental professionals' perceptions of providing SCA, and identified facilitators and barriers to its provision, there has been more limited research focusing on patients' perceptions of receiving SCA in the dental context. Accordingly, this study aimed to explore the views of smokers with periodontitis receiving dentist-delivered SCA. METHODS: One-to-one, semi-structured interviews were conducted with a purposive sample of 28 adults who smoked tobacco and had recently received SCA during dentist-delivered periodontal therapy. Participants were sampled to reflect a range of ages and smoking behaviours. The interview schedule was based on the Theoretical Domains Framework (TDF) to explore perceived influences on smoking behaviour. Interviews also elicited participants' views on dentist-delivered SCA. Interviews were audio-recorded, transcribed verbatim and analysed thematically, drawing on the TDF. RESULTS: A broad range of perceived influences on smoking behaviour emerged from the data. Influences were allocated into seven prominent TDF domains: (i) social influences (family and friends, social pressures); (ii) social/professional role and identity (secret smoking); (iii) knowledge (experiences/perceptions of smoking cessation medications); (iv) environmental context and resources (social, home and workplace environment, cost of smoking, resentment towards authority); (v) emotions (stress management, pleasure of smoking and fear of quitting); (vi) nature of the behaviour (habitual nature, link to other behaviours, smell); and (vii) beliefs about consequences (health). With regard to views on dentist-delivered SCA, five main themes emerged: (i) opportunistic nature; (ii) personal impact and tangible prompts; (iii) positive context of cessation attempt; (iv) lack of previous support; and (v) differences between dentist-delivered SCA and other setting SCA. CONCLUSIONS: Smokers with periodontitis consider that a wide range of factors influence their smoking behaviour. Dentist-delivered SCA was supported and positively received. Important aspects included the opportunistic nature, personal impact, use of tangible prompts and positive context (of the quit attempt). Future research should focus on optimizing dentist-led smoking cessation intervention based on the themes identified.
