How do dentists perceive portable dentistry? A qualitative study conducted in Quebec.

INTRODUCTION: People with impaired mobility face difficulty accessing dental care. One solution is portable dentistry, which includes delivering dental care in homes or residential institutions. Dentists, however, appear reluctant to offer such services. Our objective was to understand how dentists perceived portable dentistry and potential challenges to its implementation. METHODS: We conducted a qualitative descriptive study based on semi-structured interviews with a sample of dentists in Quebec, Canada. We employed a combination of maximum variation and snowball sampling strategies to recruit 14 participants. The interviews were conducted and audio-recorded through Zoom and lasted approximately 40 minutes. After transcribing them, we performed a thematic analysis with a combination of inductive and deductive coding. RESULTS: Despite perceiving portable dentistry as a valuable practice model, participants showed little interest in adopting this approach, arguing it was not every dentist's "job" to provide portable services. They believed portable dentistry must be financially burdensome and difficult to integrate into their daily work due to lack of time and portable equipment. Accordingly, participants considered it was the duty of governments, professional organisations overseeing dentistry education and practice, and dental schools to develop portable dentistry programs and hire dentists to deliver such services. CONCLUSIONS: To promote portable dentistry, it may be necessary to improve the knowledge and competencies of dentists, but also to challenge their professional identity as well as the current model of dental clinics as the standard of care delivery. To achieve this, we need strong leadership from dental schools, professional organisations and government.

Towards planetary oral health / Vers une santé orale planétaire

It is time to consider the protection of our environment as a major public health issue in oral medicine. Evidence shows that activities related to dental practice, such as patient transportation, use of rare materials and chemicals, or energy consumption, affect our ecosystems and contribute to the global degradation we are increasingly observing. The degradation of our environment is considered the greatest threat to our health. Exposure of oral tissues to multiple environmental factors can lead to pathological conditions. In addition to these direct effects, there are more complex phenomena, leading to co-deficits in the health of populations. The example of the sugar industry illustrates the systemic failures resulting in the double degradation of the environment and the health of individuals. Face with these dynamically interacting phenomena, human communities must consider systemic responses such as those described in this article. The dental community will need to do its part and consider global oral health as a central issue. This conceptual work will help define the innovations and action needed to ensure equitable practice that respects planetary limits.

Il est temps de considérer la protection de notre environnement comme un enjeu majeur de santé publique en médecine bucco-dentaire. Des données probantes montrent en effet que les activités liées à la pratique dentaire, comme le transport de patients, l'utilisation de matériaux rares, de produits chimiques, ou la consommation énergétique, affectent nos écosystèmes et contribuent aux dégradations planétaires que nous observons de plus en plus. Par rétroaction, la dégradation de notre environnement est considérée comme la plus grande menace pour notre santé. L'exposition des tissus de la sphère orale à de multiples facteurs environnementaux peut en effet conduire à des états pathologiques. À ces effets directs s'ajoutent des phénomènes plus complexes, induisant des co-déficits sur la santé des populations. L'exemple de l'industrie du sucre illustre les défaillances systémiques menant à la double dégradation de l'environnement et de la santé des individus. À ces phénomènes en interaction dynamique, les communautés humaines doivent envisager des réponses systémiques comme celles que nous décrivons dans cet article. La communauté dentaire devra faire sa juste part et considérer la santé orale planétaire comme un enjeu central. Ce travail conceptuel permettra de définir les innovations nécessaires et les actions adaptées pour garantir une pratique équitable et respectueuse des limites planétaires.

Dentists' Experiences and Dental Care in the COVID-19 Pandemic: Insights from Nova Scotia, Canada.

BACKGROUND: This study aimed to describe dental care provision and the perceptions of dentists in Nova Scotia, Canada, during 1 week of the COVID-19 pandemic, shortly after the closing down of non-emergency, in-person care. METHODS: A survey was distributed to all 542 registered dentists in Nova Scotia, asking about dental care provision during 19-25 April 2020. Most answers were categorical, and descriptive analyses of these were performed. Data from the 1 open-ended question were analyzed using an inductive approach to identify themes. RESULTS: The response rate was 43% (n = 235). Most dentists (181) provided care but only 13 provided in-person care. From the open-ended question, 4 concerns emerged: communication from the regulatory authority; respondents' health and that of their staff; the health of and access to care for patients; and the future of their business. CONCLUSION: Most respondents remained engaged in non-in-person dental care using various modes. They expressed concerns about their health and that of their staff and patients as well as about the future of their practice. PRACTICAL IMPLICATIONS: Dentists and dental regulatory authorities should engage in discussions to promote the health of dental staff and patients and quality of care during the chronic phase of the pandemic.

What do we know about portable dental services? A scoping review.

BACKGROUND: Delivering dental care to patients in their home or residential institutions is known as "portable dentistry". The demand for portable dental services is on the rise, but dentists remain reluctant to adopt portable practices. OBJECTIVES: To explore the literature on portable dental services and understand (a) the process of planning and delivering portable dental services and (b) the benefits and challenges of portable dentistry for service providers and patients. METHODS: A systematic scoping search was conducted. We retrieved 3994 documents, 28 of which were included in the final synthesis. Three authors read the papers and conducted thematic content analyses independently. RESULTS: We present a synthesis of the literature and proposed a model of portable dentistry containing three levels with the patient is at the centre surrounded by concentric rings representing the dentist (dental team) and society. At each of these levels, our model is further subdivided into three components: 1) organisation of the service; 2) arrival and set-up of the service; and 3) delivery of the service. In addition, each level includes 1) human factors, which are related either to the dental professional or the patient; 2) non-human factors, which refer to either the equipment or the physical environment; and 3) financial factors, which are related to cost and remuneration. CONCLUSIONS: We propose a model for portable dentistry that dentists and dental educators interested in this practice should find useful.

General practitioners' perspective on poverty: a qualitative study in Montreal, Canada.

Background: Social inequalities in healthcare systems persist worldwide. Physicians' prejudices and negative attitudes towards people living in poverty are one of the determinants of healthcare inequalities. We know very little about general practitioners' (GPs) perceptions of poverty, which shape their attitudes. Objective: To identify the perceptions of poverty of GPs who deal with it in everyday practice. Methods: A qualitative study based on interviews with GPs working in deprived urban neighbourhoods. In-depth semi-structured interviews were conducted with physicians working in disadvantaged neighbourhoods in Montreal, Canada. Interviews were audio-recorded and transcribed verbatim. Analysis consisted of interview debriefing, transcript coding, and thematic analysis using an inductive and iterative approach. Results: Our study revealed two contrasting perceptions of poverty. The global conception of poverty referred to social determinants and was shared by the majority of physicians interviewed, while the moral conception, centring on individual responsibility, was shared by a minority of participants. Conclusion: The moral judgments and misunderstandings evidenced by GPs regarding poverty suggest avenues for improving general medical training. Understanding social determinants of health should be an important component of this training, to improve access to care for people living in poverty.

Fruit and vegetable intake among Emirati adolescents: a mixed methods study.

BACKGROUND: Interventions to promote healthy eating in adolescents are needed in the United Arab Emirates. To design effective interventions, adolescent eating behaviours need to be understood. AIMS: This study aimed to describe eating behaviours of adolescents in Dubai and the factors associated with fruit and vegetable intake. METHODS: This was a sequential explanatory study using a mixed methods approach. Ten of the 34 Arabic high schools in Dubai were randomly selected and students in grades 10-12 were included. Data were collected on self-reported fruit and vegetables intake, eating behaviours, food availability and sociodemographic variables. In the qualitative phase, 14 students were interviewed about their eating behaviour. RESULTS: A total of 620 students were included: 57% were boys and most reported medium/high family affluence. Only 28% of the participants met the recommended daily fruit and vegetable intake, with significantly more males than females meeting it (P < 0.01). Lunch was the most frequently eaten meal, breakfast was frequently skipped, and there were high levels of fast food and soft drink consumption. Adequate fruit and vegetable intake was positively associated with increased lunch frequency, being male, parental support for healthy eating, and positive perception of family meals. CONCLUSIONS: There are significant differences in eating habits between Emirati male and female adolescents. Lunch, as the main family meal, faces threats because of modern working hours. The gender-specific social context may require targeted interventions to achieve optimal outcomes in each group.

Access to Dental Services for People Using a Wheelchair.

OBJECTIVES: We investigated the perspectives of people using a wheelchair and their difficulties in accessing dental services. METHODS: Our participatory research was on the basis of a partnership between people using a wheelchair, dental professionals, and academic researchers. Partners were involved in a committee that provided advice at all stages of the project. Our team adopted a qualitative descriptive design. Between October 2011 and October 2012 we conducted semistructured individual interviews with 13 adults who lived in Montreal, Québec, Canada, and used a wheelchair full time. We audio-recorded and transcribed verbatim interviews, and we interpreted data using an inductive thematic analysis. RESULTS: Oral health is of heightened importance to this group of people, who tend to use their mouth as a "third hand." We identified successive challenges in accessing dental services: finding a dentist and being accepted, organizing transportation, entering the building and circulating inside, interacting with the dental staff, transferring and overcoming discomfort on the dental chair, and paying for the treatments. CONCLUSIONS: Governments, dental professional bodies, dental schools, and researchers should work with groups representing wheelchair users to improve access to dental services.

Ideological roadblocks to humanizing dentistry, an evaluative case study of a continuing education course on social determinants of health.

BACKGROUND: Front line providers of care are frequently lacking in knowledge on and sensitivity to social and structural determinants of underprivileged patients' health. Developing and evaluating approaches to raising health professional awareness and capacity to respond to social determinants is a crucial step in addressing this issue. McGill University, in partnership with Université de Montréal, Québec dental regulatory authorities, and the Québec anti-poverty coalition, co-developed a continuing education (CE) intervention that aims to transfer knowledge and improve the practices of oral health professionals with people living on welfare. Through the use of original educational tools integrating patient narratives and a short film, the onsite course aims to elicit affective learning and critical reflection on practices, as well as provide staff coaching. METHODS: A qualitative case study was conducted, in Montreal Canada, among members of a dental team who participated in this innovative CE course over a period of four months. Data collection consisted in a series of semi-structured individual interviews conducted with 15 members of the dental team throughout the training, digitally recorded group discussions linked to the CE activities, clinic administrative documents and researcher-trainer field notes and journal. In line with adult transformative learning theory, interpretive analysis aimed to reveal learning processes, perceived outcomes and collective perspectives that constrain individual and organizational change. RESULTS: The findings presented in this article consist in four interactive themes, reflective of clinic culture and context, that act as barriers to humanizing patient care: 1) belief in the "ineluctable" commoditization of dentistry; 2) "equal treatment", a belief constraining concern for equity and the recognition of discriminatory practices; 3) a predominantly biomedical orientation to care; and 4) stereotypical categorization of publically insured patients into "deserving" vs. "non-deserving" poor. We discuss implications for oral health policy, orientations for dental education, as well as the role dental regulatory authorities should play in addressing discrimination and prejudice. CONCLUSION: Humanizing care and developing oral health practitioners' capacity to respond to social determinants of health, are challenged by significant ideological roadblocks. These require multi-level and multi-sectorial action if gains in social equity in oral health are to be made.

Providing care to vulnerable populations: a qualitative study among GPs working in deprived areas in Montreal, Canada.

BACKGROUND: Communication barriers between persons living in poverty and healthcare professionals reduce care effectiveness. Little is known about the strategies general practitioners (GPs) use to enhance the effectiveness of care for their patients living in poverty. OBJECTIVE: The aim of this study was to identify strategies adopted by GPs to deliver appropriate care to patients living in poverty. METHODS: We conducted in-depth semi-structured interviews with 35 GPs practising in Montreal, Canada, who regularly provide care to underprivileged patients in primary care clinics located in deprived urban areas. Analysis consisted of interview debriefing, transcript coding, thematic analysis and data interpretation. RESULTS: GPs develop specific skills for caring for these patients that are responsive to their complex medical needs and challenging social context. Our respondents used three main strategies in working with their patients: building a personal connection to overcome social distance, aligning medical expectations with patients' social vulnerability and working collaboratively to empower patients. With these strategies, the physicians were able to enhance the patient-physician relationship and to take into account the impact of poverty on illness self-management. CONCLUSIONS: Our results may help GPs improve the health and care experience of their vulnerable patients by adopting these strategies. The strategies' impacts on patients' experience of care and health outcomes should be evaluated as a prelude to integrating them into primary care practice and the training of future physicians.

DENTAL STUDENTS' PERSPECTIVES ON RURAL DENTAL PRACTICE: A QUALITATIVE STUDY.

INTRODUCTION: The chronic shortage of dentists in rural communities may affect the quality of care provided to these communities. The aim of this study was to explore the knowledge and perspectives of Quebec's future dentists regarding rural dental practice and their career intentions. METHODS: We conducted a qualitative study at 2 major dental faculties using the interpretive description method. Purposeful maximum variation sampling and snowball techniques were used to recruit 4th-year dental students and specialty residents as study participants. Face-to-face, semi-structured, 60-90-minute interviews were conducted and audio-recorded. Qualitative data were analyzed using a thematic approach including interview debriefing, transcript coding, data display and interpretation. RESULTS: Of the 17 interviews, 10 were with women and 7 with men; the age range of participants was 22-39 years. Five major themes emerged from the interviews: awareness of access to oral health care in rural areas, image of rurality, image of rural dental practice, perceived barriers to and perceived enablers of rural dental practice. Students said that undergraduate dental education, financial rewards, professionalism, professional support and social media may positively affect their perspective on rural dental practice. CONCLUSIONS: There is a need to implement and support strategies known to increase dental students' knowledge of rural practice and their motivation to choose rural practice. Dental educators have an essential role to play in shaping professional character and encouraging apprenticeship to meet these goals.

Impact of three genetic musculoskeletal diseases: a comparative synthesis of achondroplasia, Duchenne muscular dystrophy and osteogenesis imperfecta.

Achondroplasia, Duchenne muscular dystrophy, and osteogenesis imperfecta are among the most frequent rare genetic disorders affecting the musculoskeletal system in children. Rare genetic disorders are severely disabling and can have substantial impacts on families, children, and on healthcare systems. This literature review aims to classify, summarize and compare these non-medical impacts of achondroplasia, Duchenne muscular dystrophy and osteogenesis imperfecta.

Providing care to people on social assistance: how dentists in Montreal, Canada, respond to organisational, biomedical, and financial challenges.

BACKGROUND: Dentists report facing difficulties and experiencing frustrations with people on social assistance, one of the social groups with the most dental needs. Scientists ignore how they deal with these difficulties and whether they are able to overcome them. Our objective was to understand how dentists deal with critical issues encountered with people on social assistance. METHODS: We conducted in-depth, semi-structured interviews with 33 dentists practicing in Montreal, Canada. The interview guides included questions on dentists' experiences with people on social assistance and potential strategies developed for this group of people. Analyses consisted of interview debriefing, transcript coding, and data interpretation. RESULTS: Dentists described strategies to resolve three critical issues: missed appointments (organisational issue); difficulty in performing non-covered treatments (biomedical issue); and low government fees (financial issue). With respect to missed appointments, dentists developed strategies to maximise attendance, such as motivating their patients, and to minimise the impact of non-attendance, like booking two people at the same time. With respect to biomedical and financial issues, dentists did not find any satisfactory solutions and considered that it was the government's duty to resolve them. Overall, dentists seem reluctant to exclude people on social assistance but develop solutions that may discriminate against them. CONCLUSIONS: The efforts and failures experienced by dentists with people on social assistance should encourage us to rethink how dental services are provided and financed.

From pediatric to adult care: strategic evaluation of a transition program for patients with osteogenesis imperfecta.

BACKGROUND: Achieving a successful transition from pediatric to adult care for young adults with special needs, especially rare genetic diseases such as osteogenesis imperfecta (OI), is a prominent issue in healthcare research. This transition represents a challenge for patients with OI, their families, clinicians and healthcare managers because of the complex nature of the process and the lack of evaluation of existing transition programs. We evaluated a transition program for adolescents and young adults with OI from a pediatric orthopedic hospital to adult care. METHODS: Data were collected by interview, observation, and document review from April 2013 to October 2013. Participants included six patients with OI, four parents, and 15 staff, including administrators, coordinators, social workers, nurses, pediatricians, surgeons, occupational therapists and physiotherapists. A SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis was performed. RESULTS: The strengths of the transition program included a solid theoretical approach based on a partnership with parents, and a comprehensive transition model based on fostering independent living and professional integration. The program's main weaknesses were the successive organizational changes and discontinuation of certain transition activities, and the potential conflict between the transition program and participation in research protocols. Further opportunities include the implementation of a multi-site transition model with cross-site personnel and user evaluations, with the inclusion of second-generation patients. Dissatisfaction reported by some care-team members at the adult care hospital could threaten collaboration among institutions involved in the transition process, whereas dissatisfaction of some former patients may reduce their perceptions of quality of care received during the transition. CONCLUSIONS: This study confirmed that a "one-size-fits-all" transition model for patients with OI would be inappropriate across, or even within institutions. Opportunities should be seized to create tailored, theoretically-sound transition programs that reflect patient preferences, especially those of young adults with complex and chronic health conditions. Alignment with other organizational activities should be considered, and ongoing evaluation of transition programming may be required. This SWOT analysis and utilization-focused evaluation has led to a comprehensive new project to improve the transition program for patients with OI and other conditions requiring special follow-up.

Living with cleft lip and palate: the treatment journey.

OBJECTIVE: To better understand how individuals with cleft lip and palate (CLP) perceive and experience their treatment process and how these perceptions and experiences change over the life course. DESIGN: Qualitative in-depth semistructured interviews with 11 adults with nonsyndromal complete CLP. PARTICIPANTS/SETTING: Individuals from three Canadian cities were recruited by convenience and theoretical sampling through AboutFace International. The number of participants was determined by the principle of theoretical saturation. RESULTS: The experience of individuals with CLP through the treatment process changes over the life course. In childhood and early adolescence, most individuals experience stigma, negative self-perception, and as a result were more prone to perceiving the treatment process not only as unbearably burdensome but also as fueling their feeling of "defectiveness." In adulthood, participants' self-perception improved, partly because of definitive surgical correction, leading them to realize treatment benefits and reappraise the treatment process as satisfactory rather than burdensome. Subsequently, some individuals pursued further surgeries hoping for additional psychological gains, in lieu of psychosocial interventions addressing the underpinnings of residual feelings of "defectiveness." This led to dissatisfaction and frustration when the procedures did not lead to the hoped-for psychological gains. CONCLUSIONS: The results emphasize the importance of self-perception in determining how participants perceive several important aspects of the treatment experience throughout the life course. Further studies should focus on how to incorporate self-perception as an important variable and outcome in the treatment process.

3D printing vs traditional workflow for the fabrication of mandibular implant overdentures: study protocol for a mixed-methods cross-over RCT.

BACKGROUND: Complete tooth loss is a significant global oral health issue, particularly impacting older individuals with lower socioeconomic status. Computer-assisted technologies enhance oral healthcare access by the elderly. Despite promising in vitro reports on digital denture materials, evidence from randomized clinical trials (RCTs) is lacking to verify their performance. This cross-over RCT will investigate whether 3D-printed implant-retained mandibular overdentures (IMO) are more satisfactory for edentulous seniors than those made through traditional methods. METHODS/DESIGN: We will recruit 26 completely edentulous participants (any sex/gender) based on the following eligibility criteria: age ≥ 60 years, no tooth extraction in the past 12 months, two implants in the lower jaw, and need for new dentures in both jaws. Each participant will receive two denture pairs, either manufactured by 3D printing or traditionally, to be worn in a random order. A timeline of 3 months with each denture pair will be considered for outcome assessment (total: 6 months). Patient satisfaction with dentures will be measured by the McGill Denture Satisfaction Questionnaire. We will evaluate other patient-reported outcomes (including oral health-related quality of life) as well as clinician-assessed quality and cost. At the end of the trial, participants will choose which denture pair they wish to keep and interviewed about their experiences with the 3D-printed IMO. The quantitative and qualitative data will be incorporated through an explanatory mixed-methods strategy. A final quantitative assessment will happen after 12 months with the preferred IMO to assess the long-term performance and maintenance needs. DISCUSSION: This mixed-methods RCT will explore patient experiences with 3D-printed IMOs, aiming to assess the potential for altering clinical practice and dental public health policies. Our results will inform policies by showing whether 3D printing offers comparable outcomes at lower costs, facilitating greater access to oral care for the elderly.

The impact of severe osteogenesis imperfecta on the lives of young patients and their parents - a qualitative analysis.

BACKGROUND: Osteogenesis imperfecta (OI) is a rare genetic disorder that causes increased bone fragility. Living with, caring for, and parenting a child with OI are all highly demanding and challenging. This study is a temporal analysis of the impact of severe OI on the lives of young patients and their parents. METHODS: This study was carried out at the Shriners Hospital for Children, a pediatric orthopedic hospital located in Montreal, Canada. Using qualitative interpretative description, we conducted semi-structured interviews with 24 subjects - 12 young patients diagnosed with severe OI and 12 of their parents. The interview data were subject to a predominantly inductive open thematic analysis and a temporal comparative analysis. We did a retrospective chart review to complement our data collection. RESULTS: We found that the impact of severe OI on the young patients and their parents was characterized by four themes: 1) Starting at the time of diagnosis, a series of stages shaped life and the return to every day "normal", 2) Living with OI was full of "ups and downs" throughout life, 3) Every day "normal" life with OI consisted of significant changes for parents and challenges for the whole family, and 4) Living with OI generated some positive experiences. CONCLUSION: This study contributes to a better theoretical understanding of the impact of severe OI on families. It also has some practical implications for the development of effective support systems for patients with severe OI and their families.

How health professionals perceive and experience treating people on social assistance: a qualitative study among dentists in Montreal, Canada.

BACKGROUND: In Canada, the prevalence of oral diseases is very high among people on social assistance. Despite great need for dental treatment, many are reluctant to consult dental professionals, arguing that dentists do not welcome or value poor patients. The objective of this research was thus to better understand how dentists perceived and experienced treating people on social assistance. METHODS: This descriptive qualitative research was based on in-depth semi-structured interviews with 33 dentists practicing in Montreal, Canada. Generally organized in dentists' offices, the interviews lasted 60 to 120 minutes; they were digitally recorded and later transcribed verbatim. The interview transcripts were coded with NVivo software, and data was displayed in analytic matrices. Three members of the research team interpreted the data displayed and wrote the results of this study. RESULTS: Dentists express high levels of frustration with people on social assistance as a consequence of negative experiences that fall into 3 categories: 1) Organizational issues (people on social assistance ostensibly make the organization of appointments and scheduling difficult); 2) Biomedical issues (dentists feel unable to provide them with adequate treatment and fail to improve their oral health); 3) Financial issues (they are not lucrative patients). To explain their stance, dentists blame people on social assistance for neglecting themselves, and the health care system for not providing adequate coverage and fees. Despite dentists' willingness to treat all members of society, an accumulation of frustration leads to feelings of powerlessness and discouragement. CONCLUSIONS: The current situation is unacceptable; we urge public health planners and governmental health agencies to ally themselves with the dental profession in order to implement concrete solutions.

[Perceived oral health and use of dental services during pregnancy: the MaterniDent study]. / Santé bucco-dentaire perçue et recours aux soins pendant la grossesse : étude MaterniDent.

INTRODUCTION: The main objective of the MaterniDent study was to determine the nature and frequency of dental problems experienced by pregnant women and their associated factors. The secondary objective was to determine the frequency of dental visits during pregnancy and to identify associated factors. METHODS: The MaterniDent study was a multicenter cross-sectional study conducted among 904 postpartum women in three French maternity wards. Data were collected using self-administered questionnaires. Measured variables included socio-demographic, health and behavioral characteristics. RESULTS: 57% of women reported having experienced at least one dental problem during pregnancy, while 20% had experienced dental pain during pregnancy. Multiparity, vomiting, soda consumption and increased sugar consumption during pregnancy were significantly associated with dental pain (p<0.05). 56% of women did not visit a dentist during pregnancy, 26% consulted a dentist for a perceived problem, and 18% visited a dentist for a check-up. Younger pregnant women and those without supplemental insurance were less likely to see a dentist for a preventive dental visit (p <0.05). DISCUSSION: A significant proportion of women experienced a dental problem during pregnancy, although they did not necessarily consult a dentist to treat the problem. Given the impact of oral diseases for both mother and child, prevention and professional dental care during pregnancy should be promoted.

The experiences of people living with environmental sensitivities concerning oral health and access to dental services.

PURPOSE: Because people living with environmental sensitivities are poorly acknowledged in our society, we still know very little about their experiences navigating in the health care system, especially with respect to dental services. Our objective, therefore, was to describe their dental care pathway and better understand their experiences accessing oral health services. MATERIALS AND METHODS: A qualitative descriptive study was conducted in partnership with organizations supporting people with environmental sensitivities. Through a criterion sampling technique, 12 people living with environmental sensitivities in Quebec (Canada) were invited to participate in individual semi-structured interviews. These interviews lasted around 90 min and were transcribed to be thematically analysed. RESULTS: Participants faced major barriers accessing dental services and thus lived for long periods of time with unmet dental needs. Their dental care pathways were often delayed or even interrupted for several reasons. First because they were exposed to pollutants upon leaving their house, which rendered their trip to the dentist perilous. Second because dentists lacked knowledge about environmental sensitivities and seemed reluctant to accommodate them. CONCLUSIONS: We invite governments, dental professionals, and researchers to develop policies and clinical approaches for improving people living with environmental sensitivities' quality of life and access to dental services.IMPLICATIONS FOR REHABILITATIONAlthough environmental sensitivities are recognized as disability in several countries such as Sweden and Germany, people with these conditions face major barriers to access healthcare services.Dental professionals, for instance, are reluctant to acknowledge environmental sensitivities as a disability and seldom accommodate sufferers' special needs.We invite dentists to foster holistic and person-centered approaches and be receptive to the health conditions and needs of people with environmental sensitivities.Dentists could address oral health needs of people with environmental sensitivities by doing home-visits with portable dental equipment as this removes barriers related to their exposure to pollutants.

How to use mixed methods in oral health research.

Wicked problems exist in the realm of oral health research. Due to their inherent complexity, using qualitative or quantitative methods alone may not be adequate for resolving them. Mixed methods approaches combine qualitative and quantitative methods, and thus, can provide a powerful tool for understanding and solving complex problems in dental public health. However, using mixed methods does not come without its challenges. This commentary outlines four main tips for researchers to consider when applying mixed methods to their research projects.
