The biomedical model has been severely criticised in the last decades and its dominance challenged. This is why the concept of person-centred dentistry has penetrated the professional discourse and become a growing concern for our profession. Furthermore, dentists have been urged to take patients' environment more into account and to tackle the social determinants of their health, illness and access to care. Unfortunately, dentists still poorly comprehend person-centredness and social dentistry, and face difficulties to implement biopsychosocial approaches. To respond to these issues, we propose the Montreal-Toulouse Biopsychosocial Model for dentistry, which encompasses patient-centredness and social dentistry. Our model presents three types of tasks (understanding, decision-making and intervening) that dentists should take in each of three overlapping levels (individual, community and society). We also propose a 'Q-List', an original tool designed to help dental professionals adopting this model and reflecting upon their actions. This Q-List includes key questions to elicit dentists' reflexiveness and to support their biopsychosocial practice of dentistry. We invite dental professionals to adopt biopsychosocial approaches and use the Montreal-Toulouse Model as a guide. We also encourage them to use our Q-List and adapt it to their context of practice.

Introduction In the last decades, health professions have progressively moved towards person-centredness. Dentistry, however, lags behind the other health professions and remains deeply anchored in a biomedical vision.Aims Our objective was thus to better understand how dentists perceived person-centred care (PCC) and identify the challenges they may face in implementing it.Methods We conducted qualitative descriptive research in the province of Quebec, Canada; it was based on in-depth interviews with 11 general dental practitioners working in private clinics.Results Thematic analyses reveal that dentists had little interest in understanding the life and stories of their patients. Furthermore, their openness to share decision-making was limited to procedures that they considered of relatively low value and less for procedures they considered of higher value, such as indirect restorations.Discussion We argue that dentists' reluctance to understanding and shared decision-making is rooted in the old-established identity of dentistry as an art. Dentists indeed considered the dental craft as sacred - an art form with unbreakable axioms that defined quality of care.Conclusion It is time for the dental profession to reflect on its ideological foundations and reconsider its identity. This reflection is crucial to respond to the needs of a changing society that is losing its confidence in the profession.

Dentistry has seen a slow trend toward person-centred care (PCC), with most approaches developed by scholars who have tried to progress away from disease-centred care. Unfortunately, the perspectives and experiences of underprivileged people have not been considered in the development of these approaches. Our objective was thus to understand underprivileged people’s experiences and expectations about dental care and contribute to the development of person-centred dentistry. We conducted a qualitative descriptive study with a sample of 13 people living in poverty. We used a maximum variation sampling strategy and selected them among the users of a free dental clinic in Montreal, Canada. We conducted semi-structured interviews that we audio recorded, transcribed verbatim, and thematically analysed. Our main finding is that participants wanted to feel human and respected by dentists. More specifically, they wanted to be more involved in the dental care process through quality time and empathetic conversations with the dentist. They also wished for an exchange of information free of technical terms and built on mutual trust. In conclusion, person-centred dental care models should emphasize empathy, trust, and quality care beyond technical skills. Clinicians should provide comprehensive information in dental encounters and treat their patients as whole persons.

There is a dearth of tools designed to inform people about what to expect from person-centred dental encounters and to guide them during the care process. This is why we propose the Montreal-Toulouse Wheel of patients' expectations for dental visits, which describes what people could expect during person-centred clinical encounters. The Wheel comprises four core expectations: 1) be understood; 2) be respected; 3) have power; and 4) be given enough time. It also includes three expectations that are more specific to the process of care: 5) be informed and understand; 6) share decisions with the dentist and even co-construct the treatment plan; and 7) be comfortable during clinical procedures and the whole care process. We also propose a Q-List to help patients reflect on their relationship with dental professionals and engage them in person-centred dental care. This Q-List describes the seven expectations of the Wheel and provides open-ended questions that we invite patients to reflect upon. We also hope that dental professionals and educators will find the Wheel and the Q-List useful to develop person-centredness and promote inclusive and equitable dentistry.Key pointsThe Montreal-Toulouse Wheel of expectations presents what people should expect during person-centred dental visits.It comprises four core expectations, plus three expectations that reflect the clinical process.The Wheel of expectations comes with a Q-List - a series of open questions - to help patients reflect on their relationship with dentists and engage in person-centred care.

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.

Background Dentistry must reduce its ecological footprint in response to the triple ecological disaster of climate change, biodiversity loss, and pollution. It is thus necessary to introduce or reinforce sustainability in dental curricula and continuing education programmes. As such, this study aimed to explore how dental professionals perceive ecological issues, conceptualize and integrate sustainable practices into clinical routines, and identify their needs regarding continuing education in this domain. Methods We conducted a qualitative, exploratory study in partnership with the Ministry of Health and professional dental organizations of the province of Québec, Canada. We held six virtual focus groups (60–90 min) with a sample of 28 Québec practitioners—8 dentists, 9 dental hygienists, and 11 dental assistants—from public and private clinics. Sessions were audio-recorded, transcribed verbatim, and analyzed thematically following Braun and Clarke’s approach. Results Most participants expressed concern about climate change and a sense of responsibility toward future generations. They defined sustainability as minimizing ecological impact without compromising infection control, but acknowledged a lack of information on the subject, often equating it with waste reduction while overlooking higher-impact sources such as patient and staff travel. Their self-initiated actions, which were shaped by their professional roles, faced barriers including time pressure, hierarchical decision-making, the cost of sustainable products, and infection control rules, operating at individual, clinic, and policy levels. All groups actively wanted continuing education on sustainable dentistry, preferably in a hybrid format, and requested clear clinical protocols along with supportive procurement and regulatory policies to make change feasible. Conclusions Our analysis met the objectives by describing clinicians’ perceptions and routines, identifying needs foental professionals expressed concerns aboutr continuing education, and surfacing multilevel barriers and enablers. Accordingly, it is important to develop continuing education programmes on sustainable dentistry that are tailored to their learning preferences and professionals’ roles within the clinic. Training should be complemented by the provision of clear clinical protocols, designated sustainability leads, and procurement systems that remove cost and supply barriers.

ObjectivePatient-centred care is considered to be an important element in the evaluation of integrated healthcare and has been effective in addressing oral health disparities. This study explored the patients’ perspectives of patient-centred integrated care in oral health services integrated into a primary healthcare organisation serving a northern Quebec Cree population.DesignThis study used a multiple case study design within a qualitative approach and developmental evaluation methodology. Two theoretical models, Picker’s Principles of Patient-Centred Care and Valentijn’s Rainbow Model of Integrated Care, guided data collection and data analysis. The thematic analysis included transcription, debriefing, codification, data display and interpretation.SettingThis study was conducted in purposefully selected four Cree communities of Northern Quebec.ParticipantsAdult patients in need of oral healthcare and who attended the local dental clinic were identified and recruited by maximum variation sampling and snowball techniques.Outcome measuresPatients’ perspectives of patient-centred integrated oral healthcare.ResultsData analysis generated six major themes: enhanced accessibility, creating supportive environment, building trust through shared decision making, appreciation of public health programmes, raising oral health awareness and growing cultural humility among healthcare providers. Patients identified the integration of dental care into primary healthcare with respect to co-location, provision of free oral healthcare services, care coordination and continuity of care, referral services, developing supportive environment, shared decision making, oral health promotion and culturally competent care.ConclusionThese results confirmed that patient-centred care is an important element of integrated care. Patients valued the use of this concept in all domains and levels of integration. They recommended to further strengthen the clinical integration by involving parents in oral health promotion as well as optimising care coordination and empowering a supportive environment in organisational integration.

Despite the growing interest in understanding the psycho-social impact of rare genetic diseases, few studies examine this concept and even fewer seek to obtain feedback from families who have lived the experience. The aim of this project was to involve families of children living with osteogenesis imperfecta (OI) in the development of a tool to assess the impact of OI on the lives of patients and their families. This project used an integrated knowledge translation approach in which knowledge users (clinicians and people living with OI and their families) were consulted throughout the four steps of development, that is: content mapping, item generation, tool appraisal and pre-testing of the questionnaires. The International Classification of Functioning and Health was used as a framework for content mapping. Based on a scoping review we selected two validated tools to use as a basis for developing the questionnaire. The final parent self-report version measured six domains: experience of diagnosis; use of health services; use of social and psychological support services; expectations about tertiary specialized centers; and socio-demographic information. A total of 27 out of 40 families receiving care at the Shriners Hospital for Children-Canada and invited to participate in the pre-test returned the completed questionnaires. In more than two-thirds of families (69%; n = 18) OI was suspected either at or within the first 3 months after birth. Up to 46% of families consulted between 3 and 5 doctors (46%; n = 12) prior to final diagnosis. The use of services by families varied from 0 to 16 consultations, 0 to 9 exploratory examinations and 1 to 10 types of allied health services. In the 12 months prior to the study, fewer than a quarter of children had been admitted, for treatment, for hospital stays of longer than 8 hours or to an emergency department (24% and 9% respectively). Only 29% of parents received psychological support. This joint development process generated a tool, with good psychometric properties, that provides unique insight into the experiences of patients and families with OI, the psycho-social impact of the illness, and their service needs and expectations.

Background Overdentures retained by a single implant in the midline have arisen as a minimal implant treatment for edentulous mandibles. The success of this treatment depends on the performance of a single stud attachment that is susceptible to wear-related retention loss. Recently developed biomaterials used in attachments may result in better performance of the overdentures, offering minimal retention loss and greater patient satisfaction. These biomaterials include resistant polymeric matrixes and amorphous diamond-like carbon applied on metallic components. The objective of this explanatory mixed-methods study is to compare Novaloc, a novel attachment system with such characteristics, to a traditional alternative for single implants in the mandible of edentate elderly patients. Methods/design We will carry out a randomized cross-over clinical trial comparing Novaloc attachments to Locators for single-implant mandibular overdentures in edentate elderly individuals. Participants will be followed for three months with each attachment type; patient-based, clinical, and economic outcomes will be gathered. A sample of 26 participants is estimated to be required to detect clinically relevant differences in terms of the primary outcome (patient ratings of general satisfaction). Participants will choose which attachment they wish to keep, then be interviewed about their experiences and preferences with a single implant prosthesis and with the two attachments. Data from the quantitative and qualitative assessments will be integrated through a mixed-methods explanatory strategy. A last quantitative assessment will take place after 12 months with the preferred attachment; this latter assessment will enable measurement of the attachments’ long-term wear and maintenance requirements. Discussion Our results will lead to evidence-based recommendations regarding these systems, guiding providers and patients when making decisions on which attachment systems and implant numbers will be most appropriate for individual cases. The recommendation of a specific attachment for elderly edentulous patients may combine positive outcomes from patient perspectives with low cost, good maintenance, and minimal invasiveness.

Background The quality of the physician-patient therapeutic relationship is a key factor in the effectiveness of care. Unfortunately, physicians and people living in poverty inhabit very different social milieux, and this great social distance hinders the development of a therapeutic alliance. Social competence is a process based on knowledge, skills and attitudes that support effective interaction between the physician and patient despite the intervening social distance. It enables physicians to better understand their patients' living conditions and to adapt care to patients' needs and abilities. Methods/Design This qualitative research is based on a comprehensive design using in-depth semi-structured interviews with 25 general practitioners working with low-income patients in Montreal's metropolitan area (Québec, Canada). Physicians will be recruited based on two criteria: they provide care to low-income patients with at least one chronic illness, and are identified by their peers as having expertise in providing care to a poor population. For this recruitment, we will draw upon contacts we have made in another research study (Loignon et al., 2009) involving clinics located in poor neighbourhoods. That study will include in-clinic observations and interviews with physicians, both of which will help us identify physicians who have developed skills for treating low-income patients. We will also use the snowball sampling technique, asking participants to refer us to other physicians who meet our inclusion criteria. The semi-structured interviews, of 60 to 90 minutes each, will be recorded and transcribed. Our techniques for ensuring internal validity will include data analysis of transcribed interviews, indexation and reduction of data with software qualitative analysis, and development and validation of interpretations. Discussion This research project will allow us to identify the dimensions of the social competence process that helps physicians establish therapeutic relationships with low-income patients living with chronic illness. This study will also offer concrete recommendations for improving health interventions among low-income patients and for helping them to better manage their chronic illnesses. Ultimately, our aim is to strengthen the capacity of the health care system and of professionals to provide care that is adapted to the social conditions of people living in poverty.
