Oral health promotion activities in the workplace: a scoping review.

There is limited literature and no reviews on oral health promotion activities in the workplace to guide planning and practice. This review summarizes evidence about oral health promotion activities in the workplace (nature and extent), its impact and the factors that facilitate or act as barriers to implementation. Using the PRISMA-ScR guidelines, scientific articles written in English and published in peer-reviewed journals up to April 2021, from six databases (Medline, PubMed, CINAHL, Scopus, EMBASE and Emcare) were screened and selected. The full texts of 95 articles were then considered; 21 articles met the inclusion criteria of using oral health status or oral health predisposing factors as primary outcome after an intervention in the workplace. Almost all included articles took a quantitative approach (n = 18), two used a qualitative design and another used a mixed-method approach. The most common activities were personalized or group oral health education interventions and oral health screenings conducted by a dental professional. Two studies reported the cost-benefit of workplace oral health promotion (WOHP). The literature indicated that WOHP interventions can be successful in achieving improvements in oral health, measured using a range of clinical (plaque accumulation, gingival inflammation, periodontal inflammation) and self-rated oral health indicators. Based on the limited literature available, WOHP may have benefits for employee oral health and employers, and the support of managers and organizations potentially improves the success of programmes. The workplace would appear to be an ideal setting to promote oral health. However, there is limited information to guide oral health promotion planning and implementation, and policy.

Conceptualising a theoretical framework for planning and evaluating workplace oral health promotion programs.

ISSUED ADDRESSED: Workplaces have considerable potential for enhancing personal resources and providing a supportive working environment for staff health, including oral health and well-being. To date, assessments of workplace oral health promotion (WOHP) activities have observed benefits ranging from self-reported oral health to clinical parameters. However, previous WOHP actions were not based on a theoretical framework and did not consider the working environment as part of the planning and evaluation process. METHODS: This article used evidence-based health promotion theoretical frameworks, and associated facilitators and barriers, in constructing an integrated and theoretically robust approach to planning and evaluating oral health promotion activities in the workplace. RESULTS: The PRECEDE-PROCEED Model for planning and evaluation, the reach effectiveness adoption implementation maintenance, and the Salutogenic Model of Health were chosen to complement each other in the planning and evaluation process, based on their different features and the applicability of those features to the workplace setting. Because of the limited literature in this area, the current article also used evidence from oral health promotion in other settings (including schools and the community) and general health promotion in the workplace to construct a theoretical framework for planning and evaluating WOHP activities. CONCLUSIONS: The theoretical framework developed could assist in planning or improving existing workplace health promotion programs that focus on or incorporate oral health elements. SO WHAT?: Future research on applying and adapting the proposed framework is required.

Concurrent validity of the short-form Family Impact Scale (FIS-8) in 4-year-old US children.

BACKGROUND: US data on the validity and reliability of the short-form Family Impact Scale (FIS-8; a scale for measuring the impact of a child's oral condition on his/her family) are lacking. METHODS: Cross-sectional analysis of data on four-year-old US children taking part in a multi-center cohort study. For child-caregiver dyads recruited at child age 12 months, the impact of the child's oral condition on the family was assessed at age 48 months using the FIS-8, with a subsample of 422 caregivers (from 686 who were approached). Internal consistency reliability was assessed using Cronbach's α, with concurrent validity assessed against a global family impact item ("How much are your family's daily lives affected by your child's teeth, lips, jaws or mouth?") and a global oral health item ("How would you describe the health of your child's teeth and mouth?"). RESULTS: Cronbach's alpha was 0.83. Although gradients in mean scores across ordinal response categories of the global family impact item were inconsistent, there were marked, consistent gradients across the ordinal categories of the global item on the child's oral health, with scores highest for those rating their child's oral health as 'Poor'. CONCLUSIONS: While the findings provide some evidence for the utility of the FIS in a US child sample, the study's replication in samples of preschoolers with greater disease experience would be useful.

Neoliberalism and Indigenous oral health inequalities: a global perspective.

Neoliberalism is the dominant ideology underpinning the operation of many governments. Its tenets include policies of economic liberalization such as privatization, deregulation, free trade and reduced public expenditures on infrastructure and social services. Champions of neoliberalism claim that expansion of global trade has rescued millions from abject poverty and that direct foreign investment successfully transfers technology to developing economies. However, critics have urged governments to pay greater attention to how neoliberalism shapes population health. Indigenous populations experience inequalities in ways that are unique and distinct from the experiences of other marginalised groups. This is largely due to colonial influences that have resulted in sustained loss of lands, identity, languages and the control to live life in a traditional, cultural way that is meaningful. Oral health is simultaneously a reflection of material circumstances, structural inequities and access to health services. Indigenous populations carry a disproportionate burden of oral health inequalities at a global level. In this commentary, we contend that neoliberalism has overwhelmingly contributed to these inequities in three ways: (1) increased dominance of transnational corporations; (2) privatization of health and; (3) the neoliberal emphasis on personal responsibility.

The Dunedin Multidisciplinary Health and Development Study: Oral health findings and their implications.

Longitudinal research is needed to better understand the natural history of oral conditions and long-term health and social outcomes. Oral health data has been collected periodically in the Dunedin Multidisciplinary Health and Development Study for over 40 years. To date, 70+ peer-review articles on the Study's oral health-related findings have been published, providing insight into the natural history of oral conditions, risk factors, impacts on quality of life, and disparities in oral health. Some of these report new findings, while others build upon the existing body of evidence. This paper provides an overview of these findings and reflects on their public health implications and policy utility in New Zealand.

The effect of bitewing radiography on estimates of dental caries experience among children differs according to their disease experience.

BACKGROUND: Radiography is a regularly used and accepted adjunct to visual examination in the diagnosis of dental caries. It is assumed that not using radiographs can lead to underestimation of dental caries experience with most reports having involved studies of young adults or adolescents, and been focused on the permanent dentition. The aim of this study was to determine the relative contributions of bitewing radiography and clinical examination in the detection of dental caries in primary molars and to determine whether those contributions differ according to caries experience. METHODS: A cross-sectional study was conducted, involving examinations undertaken in dental clinics. Bitewing radiographs taken at the time of the clinical examination were developed and read later, with the data from those used at the analysis stage to adjust the caries diagnosis for the mesial, occlusal and distal surfaces of the primary molar teeth. Children's clinically determined dmfs score was used to allocate them to one of three caries experience groups (0 dmfs, 1-8 dmfs, or 9+ dmfs). RESULTS: Of the 501 three-to-eight-year-old children examined, nearly three-quarters were younger than six. Caries prevalence and mean dmfs after clinical examination alone and following radiographs were 63.1% and 4.6 (sd, 6.2), and 74.7% and 5.8 (sd, 6.5) respectively. Among children with a dmfs of 1-8, the number of lesions missed during the clinical examination was greater than the number of 106 (25.6%) in children with a dmfs of 9+. In the 185 children with no apparent caries at clinical examination, 124 lesions were detected radiographically, among 58 (46.8%) of those. CONCLUSIONS: Taking bitewing radiographs in young children is not without challenges or risks, and it must be undertaken with these in mind. Diagnostic yields from bitewing radiographs are greater for children with greater caries experience. The findings of this study further support the need to consider using bitewing radiographs in young children to enhance the management of lesions not detected by a simple visual examination alone.

Efficacy of Codeine When Added to Paracetamol (Acetaminophen) and Ibuprofen for Relief of Postoperative Pain After Surgical Removal of Impacted Third Molars: A Double-Blinded Randomized Control Trial.

PURPOSE: The use of opioids in combination with nonopioids is common practice for acute pain management after third molar surgery. One such combination is paracetamol, ibuprofen, and codeine. The authors assessed the efficacy of codeine when added to a regimen of paracetamol and ibuprofen for pain relief after third molar surgery. MATERIALS AND METHODS: This study was a randomized, double-blinded, placebo-controlled trial conducted in patients undergoing the surgical removal of at least 1 impacted mandibular third molar requiring bone removal. Participants were randomly allocated to a control group (paracetamol 1,000 mg and ibuprofen 400 mg) or an intervention group (paracetamol 1,000 mg, ibuprofen 400 mg, and codeine 60 mg). All participants were treated under intravenous sedation and using identical surgical conditions and technique. Postoperative pain was assessed using the visual analog scale (VAS) every 3 hours (while awake) for the first 48 hours after surgery. Pain was globally assessed using a questionnaire on day 3 after surgery. RESULTS: There were 131 participants (36% men; control group, n = 67; intervention group, n = 64). Baseline characteristics were similar for the 2 groups. Data were analyzed using a modified intention-to-treat analysis and, for this, a linear mixed model was used. The model showed that the baseline VAS score was associated with subsequent VAS scores and that, with each 3-hour period, the VAS score increased by an average of 0.08. The treatment effect was not statistically meaningful, indicating there was no difference in recorded pain levels between the 2 groups during the first 48 hours after mandibular third molar surgery. Similarly, the 2 groups did not differ in their global ratings of postoperative pain. CONCLUSION: Codeine 60 mg added to a regimen of paracetamol 1,000 mg and ibuprofen 400 mg does not improve analgesia after third molar surgery.

Self-reported oral behaviour habits in hyperdivergent and normodivergent facial types.

The relationship between facial morphology and jaw function remains controversial. The purpose of this study was to investigate differences in self-reported oral behaviour habits between individuals with normodivergent and hyperdivergent facial types. Some 80 cases and controls were individually matched on age, sex ethnicity and treatment stage. The participants were recruited from an orthodontic clinic, and included both adolescents and adults. Habitual oral activity was assessed using the Oral Behaviour Checklist (OBC) based on their experiences in the past 4 weeks. Univariate and bivariate analyses were performed. The sample had a mean age of 17·2 years (SD = 4·6; range = 12-49 years), and was predominantly female (65·0%) and of New Zealand European origin (91·3%). The prevalence of reporting one or more frequently performed habitual muscular behaviour in either study group was over 85% (P > 0·05). There was no difference in total OBC score between the hyperdivergent (25·6; SD: 9·0) and normodivergent group (25·3; SD: 9·9). Moreover, there was no difference in the prevalence of either nocturnal or daytime oral behaviours between the two groups. While this study did not include any objective measures of functional or habitual activity, we found no differences in self-reported oral behaviour habits between normodivergent and hyperdivergent individuals. The findings do not support an association between vertical facial form and habitual muscular activity.

Self-report of temporomandibular joint clicking and psychological factors: is there an association?

The objectives of this study were to test the hypothesis that self-reported TMJ clicking sounds in adolescents are positively associated with non-specific somatic symptoms, self-perception of body image and care-seeking behaviour. A cross-sectional study was carried out in 353 young adolescents (48·4% females) recruited from community (N = 272) and orthodontic clinic (N = 81) settings. Assessments included self-reported TMJ clicking, non-specific physical symptoms, body image concerns and for the clinic sample only, the source of motivation for treatment. TMJ sounds were self-reported by 19% of the sample and were associated with higher scores for non-specific physical symptoms and body image concerns (P < 0·001). Adolescents who were self-motivated to seek orthodontic treatment had greater scores for non-specific physical symptoms, more body image concerns and tended to report TMJ sounds more often (26·3% and 7·7% respectively; P = 0·41) than those who were solely parent/family-motivated to seek treatment. Self-reported TMJ sounds in adolescents were associated with a propensity to somatisation and concerns with body image. Care-seeking adolescents have greater non-specific physical symptoms and body image concerns and tend to report more frequent TMJ sounds.

The learning environment in professional doctorate and postgraduate dental education: a qualitative study.

INTRODUCTION: Currently, there is a lack of studies focusing on professional doctoral students' and graduates' perceptions of their learning environment, in particular, using a qualitative approach to elicit in-depth information. This article aims to contribute to the existing body of knowledge by systematically exploring, critically analysing and getting a deeper understanding of professional doctorate dental students' and graduates' insights into effective and ineffective clinical and physical learning environment characteristics. METHODS: The study included a total of 20 participants. Participants included 16 final-year Doctor of Clinical Dentistry (DClinDent) students and four dental specialists (graduates of the DClinDent programme). Semi-structured, individual interviews were used. Participants were asked to reflect upon and describe in detail their effective and ineffective learning environment experiences. The critical incident technique was used to guide the data collection. Data were analysed using a general inductive qualitative approach. RESULTS: Learning environment characteristics which participants associated with effective learning included the following: sufficient opportunities for comprehensive treatment planning; introduction to a number of patient treatment philosophies; a sufficient number of complex cases; clinically oriented research and assignment topics; a focus on clinical training in the programme generally; a research topic of a realistic depth and breadth, suitable for their 'specialist training' degree; and a well-resourced and updated physical infrastructure. On the other hand, most participants indicated that the absence of an adequate number of clinical cases, an overemphasis on research (as opposed to clinical practice) in the DClinDent programme and an 'outdated' physical infrastructure in the dental school clinics could hamper effective clinical learning. CONCLUSION: These findings contribute to the meaningful advancement of the literature on learning environment strategies through the exploration of (and in-depth qualitative insights into) what facilitated effective learning by New Zealand professional doctorate candidates and graduates. These findings provide a starting point for reflection by international academic directors, educational developers, curriculum planners, programme managers and clinical teachers in respect of the further development of the learning environment. Although the findings from this study may not be directly transferable to all international contexts, they have the potential to contribute to the further development of theory in this area.

Validity of self-reported periodontal questions in a New Zealand cohort.

OBJECTIVE: This study aims to assess the validity of four self-reported questions for measuring periodontitis in a birth cohort. METHODS: Full-mouth periodontal examinations (three sites/tooth) were undertaken at age 38 in a complete birth cohort born in 1972/1973 in New Zealand. Four self-reported periodontal screening questions were included ("Do you think you have gum disease"; "Has a dental professional ever told you that you have lost bone around your teeth"; "Have you ever had scaling, root planing, surgery, or other treatment for gum disease" and "Have you ever had any teeth that have become loose by themselves without some injury"), and the sensitivity and specificity of those self-reported items were calculated for individual questions and using a multivariable binary logistic regression model. Generalised linear models were used to compare relative risks for periodontitis and smoking, using the (a) clinical measures and (b) self-reported questions. RESULTS: Among the 895 who had periodontal examinations, the prevalence of periodontitis was 43.7, 22.8 and 12.0 %, respectively, for one or more sites with ≥4, ≥5 and ≥6 mm clinical attachment loss (AL). The specificity of the four self-reported questions was high (82-94 %), but the sensitivity was low for all, except the question: "Do you think you have gum disease". The four questions' highest combined sensitivity + specificity value was 1.33 for one or more sites with ≥4 mm AL, with the area under the receiver operating characteristic (ROC) curve being greatest for one or more sites with ≥6 mm AL, at 0.84. For the smoking-periodontitis association, the estimates of relative risk for periodontitis among smokers were as follows: (a) 1.81, 2.88 and 5.79, respectively, clinically determined to have one or more sites with ≥4, ≥5 and ≥6 mm AL and (b) 2.19, 2.17, 1.23 and 1.89, respectively, for the four self-reported questions. CONCLUSION: The four self-reported periodontal screening questions performed adequately in identifying clinically determined periodontal disease, and they showed moderate validity when used together as a set. However, the strength of the association between smoking and periodontitis was underestimated when they were used instead of clinically determined periodontal disease. CLINICAL RELEVANCE: These findings suggest that clinical examinations remain to be the desired approach for periodontal surveys, but where resource constraints preclude those, self-reported methods can provide useful information; after all, some periodontal information is better than none at all.

Dental implant use in New Zealand: A 10-year update.

OBJECTIVE: The aim of this study was to explore changes in dentists' promotion and use of implants in New Zealand over the past 10 years. METHODS: A postal survey was conducted of a random sample of 807 New Zealand registered dentists, using a 23-item questionnaire adapted from one used in a similar survey in 2004. RESULTS: The participation rate was 54.3%. In the past 10 years, the percentage of dentists providing an implant service has increased from 49.4% to 68.0%, with an equal proportion of females now providing this service. Single missing teeth (56.9%) and trauma (51.5%) are the most common clinical situations in which implants are provided. Patient enquiries about implants have slightly increased. A need for continuing education, particularly in the area of implant prosthetic procedures, was noted by 76.5%. Despite more proprietary implant systems now being available, the most commonly used system has remained unchanged. Cost is still the primary barrier to implementing implant treatment. CONCLUSIONS: Although dental implant use in New Zealand has increased, it appears that a need exists for continuing education, particularly for implant prosthetic procedures. The perceived expense of treatment continues to hinder optimal utilisation.

Steroid Prophylaxis: The knowledge and practices of New Zealand General Dental Practitioners.

OBJECTIVE: To describe the knowledge and practices of New Zealand (NZ) General Dental Practitioners (GDPs) concerning the use of steroid prophylaxis. METHODS: An online survey was conducted in 2013 involving a sample of 500 NZ GDPs who met inclusion criteria and had email addresses on the Dental Council register. RESULTS: A total of 214 dentists responded, giving a 44.5% response rate after accounting for undelivered questionnaires. Nearly two-thirds (61 .7%) did not currently recommend corticosteroid prophylaxis, although nearly three-quarters (74.8%) believed that dental treatment posed a potential risk to patients with adrenal suppression. Over half (53.4%) believed that oral corticosteroids could cause adrenocortical suppression, and a similar proportion (58.3%) believed that a specific dose of oral prednisolone of 7.5 mg per day could do so. Most practitioners (79.6%) supported the formulation of steroid prophylaxis guidelines. CONCLUSION: Despite most NZ GDPs believing the dental setting to pose a risk of adrenal crisis for patients taking corticosteroids, there is some confusion among dentists identifying at-risk patients and their ability to manage if such an event was to occur in their practices. There is further confusion over whether steroid prophylaxis is warranted for perceived at-risk patients, and which regime to follow when it is. There is an associated tendency to be over-cautious when determining the need for steroid prophylaxis, and to rely on their undergraduate steroid prophylaxis guidelines when doing so. There is a need for evidence-based guidelines to be formulated by an expert panel.

Ethnic and socioeconomic inequalities in dental treatment at a school of dentistry.

BACKGROUND AND OBJECTIVES: Health services should be targeted toward those most in need of health care. Poor oral health disproportionately affects Maori, Pacific Island, and socioeconomically deprived New Zealanders of all ages, and oral health care services should be prioritised to such groups. In New Zealand, free oral health care is available for all children up to the age of 17. On the other hand, adult dental services are provided on a user-pays basis, except for a limited range of basic services for some adults, access to which varies regionally. This study investigated the extent of dental treatment inequalities among patients at New Zealand's only School of Dentistry. METHODS: Data were audited for all treatments provided at the University of Otago Faculty of Dentistry from 2006 to 2011 for patients born prior to 1990. Ethnic and socioeconomic inequalities in the provision of dental extractions, endodontic treatment, crowns, and preventive care were investigated. Differences were expressed as the odds of having received one or more treatments of that type during the six-year period 2006 to 2011. RESULTS: Data were analysed for 23,799 individuals, of whom 11,945 (50.2%) were female, 1,285 (5.4%) were Maori and 479 (2.0%) were Pacific, 4,040 (17.0%) were of low socioeconomic status (SES), and 2,681 (11.3%) were beneficiaries or unemployed. After controlling for SES, age, and sex, Maori had 1.8 times greater odds of having had a tooth extracted than NZ European patients, while Pacific Islanders had 2.1 times the odds. Furthermore, after controlling for ethnicity, age, and sex, low-SES patients had 2.4 times greater odds of having had a tooth extracted than high-SES patients, and beneficiaries had 2.9 times the odds. Conversely, these groups were less likely to have had a tooth treated with a crown or endodontics or receive preventive care. CONCLUSIONS: Existing policies call for the reduction of inequalities. There is a need for a strategy to monitor changes in treatment inequality over time which includes improving equity in service care provision. The observed treatment inequalities are likely to be an underestimate of those occurring in private dental practice in New Zealand.

Stress and coping in fourth-year medical and dental students.

UNLABELLED: Medicine and dentistry are stressful professions. Dental and medical students suffer high levels of stress and may experience adverse psychological symptoms and use dysfunctional coping mechanisms. AIM: To investigate levels and sources of stress, anger, anxiety and sadness, and associated coping mechanisms, in fourth-year dental and medical students. METHODS: A link to an online questionnaire was emailed to all fourth-year dental and medical students at the University of Otago, in Dunedin (New Zealand). RESULTS: The response rate was 60.2% (N = 100). The majority of students (58.6%) reported frequently feeling stressed. More dental than medical students reported always feeling stressed, but a greater proportion of medical students reported not coping well with stress, suffering abnormal anxiety, anger and sadness, and having these feelings for prolonged periods. Destructive coping mechanisms were more common among dental students, while positive coping mechanisms were also used by both groups. Few students (13.5%) reported using professional counselling services during their undergraduate years. CONCLUSIONS: Mental stability is indispensable for the compassionate, professional and competent delivery of care by health professionals. The high prevalence of detrimental emotions and adverse mental states reported by students before they enter the health workforce is alarming and needs to be addressed.

A qualitative study of the meaning of oral health and self-care for 40 Dunedin residents living on lower incomes.

BACKGROUND AND OBJECTIVES: This project extends studies of oral health cultures for lower income families by identifying the participants' meaning of oral health self-care, barriers to its attainment, and suggestions for its improvement. METHODS: Forty open-ended interviews were conducted with Dunedin residents purposively selected from a variety of ages, backgrounds and ethnicities. Transcribed interviews were analysed thematically. RESULTS: Five key themes emerged: (1) oral health understandings for self and wider family groups; (2) the complexity of understanding cost in relation to oral self-care; (3) oral self-care tools and daily oral health routines; (4) relationships with oral health workers and the meaning of good and bad care provision; and (5) the State's involvement in oral health. CONCLUSIONS: Participants valued good oral health and were knowledgeable about it, but cost was the primary barrier to care.
