Effect of treating carious teeth on children's and adolescents' anthropometric outcomes: A systematic review of randomised controlled trials.

OBJECTIVE: To examine the impact of treating carious teeth on children's and adolescents' anthropometric outcomes. BASIC RESEARCH DESIGN: Four electronic databases and four electronic clinical trials registries were searched. Two reviewers independently conducted the screening, data extraction and critical appraisal. The Cochrane Risk of Bias Tool for Randomised Controlled Trials was used to assess the risk of bias in the included studies. RESULTS: The searches yielded 399 potential studies. Following deduplication and screening of the papers, four were considered eligible for inclusion of which two referred to the same study. None of the included studies was found to have a high risk of bias in any of the domains. However, performance bias was deemed of unclear risk in all studies. One of the studies found that following extraction of pulpally involved teeth, underweight children exhibited a statistically significant improvement in their weight-for-age (change in mean=0.26; p⟨0.001) and BMI-for-age z scores (change in mean=0.52, p⟨0.001) and had a significant weight gain (change in mean=1.2; p⟨0.001). Two studies showed that dental intervention did not have a significant effect on anthropometric outcomes. Treatment of caries significantly improved children's oral health-related quality of life in two studies. CONCLUSIONS: The evidence into the impact of treating carious teeth on children's growth is mixed and inconclusive. However, there is consistent evidence that treatment of severely carious teeth can significantly improve children's oral health-related quality of life. Oral health promotion and strategies to screen for oral health problems and widen dental access should be considered as part of integrated public health programs targeting children.

To what extent do patients' racial characteristics affect our clinical decisions?

Design The study employed a randomised controlled trial methodology and it was delivered electronically as a survey. Intervention Fifty-seven primary and secondary care dentists were randomised to two experimental groups. The participants in both groups assessed a vignette (clinical scenario, clinical photograph and radiograph) with the only difference between the vignettes in the two groups being the patient's race (skin colour: Black or White). The scenario was a case of a severely carious first lower molar with signs and symptoms of irreversible pulpitis.Outcome measures The dentists' clinical treatment decisions (recommendation of root canal treatment or extraction) were recorded. A previously validated Brief Implicit Association Test (BIAT) was used to measure implicit racial bias.Results A statistically significant difference in dentists' recommendations was observed. Recommendation of root canal treatment was greater for White patients (86.21%) compared to the Black patients (60.71%) and dentists were far more likely to recommend extraction in the Black patient group. The BIAT scores also indicated that pro-White unconscious racial bias was prevalent amongst the participants. Conclusion A patient's race may influence a dentist's decision whether to extract or retain a decayed tooth.

Can we deliver effective alcohol-related brief advice in general dental practice?

Design Two-arm cluster randomised controlled feasibility trial. Intervention Twelve NHS dental practices were randomised to the intervention and control arms. Patients consuming alcohol above the recommended levels were eligible to participate in the trial. The intervention was delivered by the dentists in the participating practices and entailed the delivery of a short tailored alcohol-related advice tool and a leaflet, which included information about the effects of alcohol on oral health and the benefits of reducing alcohol intake to both oral and general health. Patients in the control arm were given a mouth cancer prevention leaflet only. The level of alcohol consumption was measured by validated tools (AUDIT: Alcohol Use Disorders Identification Test and AUTID-C: Alcohol Use Disorders Identification Test for Consumption). The patients were followed-up after six months by a telephone interview. Outcome Measures The feasibility trial outcomes were the recruitment, retention, eligibility and delivery rate. The primary outcome of the trial was the impact of the intervention in lowering the level of alcohol consumption as captured by the AUDIT tool. Secondary outcomes included health related quality of life and alcohol consumption and abstinence in the last 90 days. The acceptability of the intervention was also assessed.Results The recruitment and retention rate were high (95.4% and 76.9% respectively). At the follow-up, participants in the intervention arm were significantly more likely to report a longer abstinence period (3.2 vs. 2.3 weeks respectively, P = 0.04). Non-significant differences in AUDIT (44.9% vs. 59.8% AUDIT positive respectively, P = 0.053) and AUDIT-C between baseline and follow-up (-0.67 units vs. -0.29 units respectively, P = 0.058) were observed. Results from the process evaluation indicated that the intervention and study procedures were acceptable to dentists and patients.Conclusion According to this study, dentists offering screening for alcohol misuse and brief advice in a primary dental care setting is not only feasible but also well-welcomed by both the dental team and patients.

The role of ergonomic saddle seats and magnification loupes in the prevention of musculoskeletal disorders. A systematic review.

OBJECTIVES: Musculoskeletal disorders affect a high percentage of dentists, dental hygienists and therapists. Static and awkward working postures are considered as major risk factors. Proper seat selection and use of magnification loupes are promoted for their ergonomic benefits. The aim of this review was to evaluate the existing empirical evidence on the effect of the above interventions on (i) correction of poor posture and (ii) reduction in musculoskeletal pain. METHODS: The review was conducted according to the PRISMA guidelines. The review protocol was registered with PROSPERO (CRD42017058580). The Medline via Ovid, CINHAL via EBSCO, Web of Science, OpenGrey and EThOS electronic databases were searched. Prospective experimental studies were considered for inclusion. The Effective Public Health Practice Project Quality Assessment Tool (EPHPP) was used to assess the methodological quality of the included studies. RESULTS: Eight studies were included in the review. Four investigated the effect of loupes on posture and musculoskeletal pain, 4 the effect of the saddle seats on posture and one of the latter explored the combined effect of magnification and use of saddle seats on posture. CONCLUSIONS: Based on a limited number of studies, the use of ergonomic saddle seats and dental loupes leads to improved working postures. The use of loupes appears to relieve shoulder, arm and hand pain. However, their effect on neck pain is scarce. None of the studies reported on the effect of the saddle seats on musculoskeletal pain. Future well-powered prospective longitudinal studies are deemed necessary to confirm the conclusions of this review.

Impact of stress on dentists' clinical performance. A systematic review.

INTRODUCTION: Dentistry is recognised as a stressful profession and dentists perceive their profession to be more stressful than other healthcare professions. While earlier studies have shown a link between stress and well-being among dentists, whether stress negatively impacts their clinical performance is an important and open question. We do know, however, that stress is associated with reduced performance in other health (and non-health) related professions. OBJECTIVES: This systematic review aimed to answer the question: how does stress impact on dentists' clinical performance? METHODS: This systematic review was registered in PROSPERO (CRD42016045756). The CINHAL, Embase, Medline, PsycINFO, EThOS and OpenGrey electronic databases were searched according to PRISMA guidelines. Two reviewers independently screened the citations for relevance. The citation list of potentially eligible papers was also searched. Prospective empirical studies were considered for inclusion. The inclusion criteria were applied at the full-text stage by the two same reviewers independently. RESULTS: The search yielded 3535 titles and abstracts. Twelve publications were considered potentially eligible, eleven of which were excluded as they did not meet the predefined inclusion criteria. CONCLUSIONS: This systematic review identified a gap in the literature as it found no empirical evidence quantifying the impact of stress on dentists' clinical performance. Prospective well-designed experimental simulation studies, comparing stress with non-stress situations on clinical performance and decision making, as well studies evaluating prospectively real-life dentists' performance under stress are warranted.

Dental and periodontal complications of lip and tongue piercing: prevalence and influencing factors.

BACKGROUND: The aim of this study was to compare the prevalence of lip and tongue piercing complications and explore the effect of ornament time wear period, habits, ornament morphology and periodontal biotype on the development of complications. METHODS: One hundred and ten subjects with 110 lip and 51 tongue piercings were assessed for abnormal toothwear and/or tooth chipping/cracking (dental defects), gingival recession, clinical attachment loss and probing depth of teeth adjacent to the pierced site. Piercing habits (biting, rolling, stroking, sucking) were recorded. RESULTS: Wear time and habits significantly affected the prevalence of dental defects and gingival recession. Pierced site significantly affected dental defects prevalence, with greater prevalence for tongue than lip piercing. Wear time significantly affected attachment loss and probing depth. Attachment loss and probing depth did not significantly differ between tongue and lip piercings. Gingival recession was significantly associated with ornament height closure and stem length of tongue ornaments. Periodontal biotype was not significantly associated with gingival recession, attachment loss and probing depth. CONCLUSIONS: Dental defects prevalence is greater for tongue than lip piercing. Gingival recession is similar for tongue and lip piercing. Longer wear time of tongue and lip piercing is associated with greater prevalence of dental defects and gingival recession, as well as greater attachment loss and probing depth of teeth adjacent to pierced sites. Ornament morphology affects gingival recession prevalence.
