A Systematic Umbrella Review of the Effects of Teledentistry on Costs and Oral-Health Outcomes.

Teledentistry offers possibilities for improving efficiency and quality of care and supporting cost-effective healthcare systems. This umbrella review aims to synthesize existing systematic reviews on teledentistry and provide a summary of evidence of its clinical- and cost-effectiveness. A comprehensive search strategy involving various teledentistry-related terms, across seven databases, was conducted. Articles published until 24 April 2023 were considered. Two researchers independently reviewed titles, abstracts and full-text articles. The quality of the included reviews was critically appraised with the AMSTAR-2 checklist. Out of 749 studies identified, 10 were included in this umbrella review. Two reviews focusing on oral-health outcomes revealed that, despite positive findings, there is not yet enough evidence for the long-term clinical effectiveness of teledentistry. Ten reviews reported on economic evaluations or costs, indicating that teledentistry is cost-saving. However, these conclusions were based on assumptions due to insufficient evidence on cost-effectiveness. The main limitation of our umbrella review was the critically low quality of the included reviews according to AMSTAR-2 criteria, with many of these reviews basing their conclusions on low-quality studies. This highlights the need for high-quality experimental studies (e.g., RCTs, factorial designs, stepped-wedge designs, SMARTs and MRTs) to assess teledentistry's clinical- and cost-effectiveness.

Terminology of e-Oral Health: Consensus Report of the IADR's e-Oral Health Network Terminology Task Force.

OBJECTIVE: Authors reported multiple definitions of e-oral health and related terms, and used several definitions interchangeably, like mhealth, teledentistry, teleoral medicine and telehealth. The International Association of Dental Research e-Oral Health Network (e-OHN) aimed to establish a consensus on terminology related to digital technologies used in oral healthcare. METHOD: The Crowdsourcing Delphi method used in this study comprised of four main stages. In the first stage, the task force created a list of terms and definitions around digital health technologies based on the literature and established a panel of experts. Inclusion criteria for the panellists were: to be actively involved in either research and/or working in e-oral health fields; and willing to participate in the consensus process. In the second stage, an email-based consultation was organized with the panel of experts to confirm an initial set of terms. In the third stage, consisted of: a) an online meeting where the list of terms was presented and refined; and b) a presentation at the 2022-IADR annual meeting. The fourth stage consisted of two rounds of feedback to solicit experts' opinion about the terminology and group discussion to reach consensus. A Delphi-questionnaire was sent online to all experts to independently assess a) the appropriateness of the terms, and b) the accompanying definitions, and vote on whether they agreed with them. In a second round, each expert received an individualised questionnaire, which presented the expert's own responses from the first round and the panellists' overall response (% agreement/disagreement) to each term. It was decided that 70% or higher agreement among experts on the terms and definitions would represent consensus. RESULTS: The study led to the identification of an initial set of 43 terms. The list of initial terms was refined to a core set of 37 terms. Initially, 34 experts took part in the consensus process about terms and definitions. From them, 27 experts completed the first rounds of consultations, and 15 the final round of consultations. All terms and definitions were confirmed via online voting (i.e., achieving above the agreed 70% threshold), which indicate their agreed recommendation for use in e-oral health research, dental public health, and clinical practice. CONCLUSION: This is the first study in oral health organised to achieve consensus in e-oral health terminology. This terminology is presented as a resource for interested parties. These terms were also conceptualised to suit with the new healthcare ecosystem and the place of e-oral health within it. The universal use of this terminology to label interventions in future research will increase the homogeneity of future studies including systematic reviews.

Teledentistry for improving access to, and quality of oral health care: A protocol for an overview of systematic reviews and meta-analyses.

Digital technologies are becoming essential to address and optimize the suboptimal performance of healthcare systems. Teledentistry involves the use of information and communication technology to improve access to oral health care and the quality of oral health care delivery. Several systematic reviews (SRs) have been conducted to synthesize evidence on the effectiveness of teledentistry but with conflicting results. The aim of this review is to comprehensively summarize available SRs and provide evidence on the impact of teledentistry on access to oral care, patients' and oral healthcare providers' outcomes, quality of oral health care and costs. This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42022373964). Six electronic databases including MEDLINE (Ovid), Embase (Embase.com), CINAHL (EBSCO), Web of Science, Cochrane Library and Epistemonikos will be searched for SRs of quantitative, qualitative, and mixed reviews evaluating teledentistry modalities involving both patients and/or oral health care providers (OHCPs). We will include studies published in English or French. The outcomes will include patients' outcomes (e.g., access to oral health care, patient-reported outcomes, and patient-reported experiences); patient indicators (e.g., clinical outcomes, adherence to treatment, adverse outcomes and costs); and OHCP indicators (e.g., diagnostic accuracy, barriers and enablers costs and equity). Two independent reviewers will perform data screening, data extraction and will assess the quality of included studies using AMSTAR 2 and ROBIS tools. Data will be synthesized narratively and presented by tables and graphs. We will report any overlap of primary studies in the SRs. A statement on the strength of evidence for each outcome will be provided if possible. This review will inform decision-makers, patients, OHCPs, and researchers on the potential effectiveness, benefits, and challenges of teledentistry and support them in making recommendations for its use. Results will be disseminated through peer-reviewed publications, presentations at conferences, and on social media.

The e-DENT teledentistry project: Achievements, lessons learned, and perspectives / Le projet de télémédecine bucco-dentaire e-DENT : réalisations, enseignements et perspectives

In October 2010, the decree n°2010­1229 relating to telemedicine, published in the "Journal officiel de la république française" (JORF) n°0245 of October 21, 2010, specified the terms of the application of telemedicine in France. The practice of remote oral medicine is now becoming more widespread in the country. Since 2010, the dental public health team of the University Hospital (CHU) of Montpellier and the University of Montpellier has been working on the subject, with nearly ten thousand telemedicine acts performed as part of the work of the "First consultation and telemedicine" Medical Activity Unit of the Center for Dental Care, Teaching and Research (CSERD) of the CHU of Montpellier. Various studies have been conducted with multiple target populations to evaluate the value of teledentistry in different settings. The practice of teledentistry should help fight against inequalities of access to care and prevention in France. It has shown to be beneficial for patients, health professionals, dentists and health institutions, but improvements are needed to structure and perpetuate this practice. The profession must make major decisions and relaunch discussions so that France remains one of the leaders in this field.

Le décret no 2010-1229 relatif à la télémédecine, paru au Journal officiel de la République française (JORF) no 0245 du 21 octobre 2010, a précisé les modalités d'application de la télémédecine. La pratique de la médecine bucco-dentaire à distance commence à se faire une place en France. Depuis 2010, l'équipe de santé publique orale du Centre hospitalier universitaire (CHU) de Montpellier et de l'université de Montpellier travaille sur le sujet avec près de 10 000 actes de télémédecine réalisés dans le cadre de l'Unité d'activité médicale de « Première consultation et télémédecine ¼ du Centre de soins, d'enseignement et de recherche dentaire (CSERD) du CHU de Montpellier. Différentes études ont été menées auprès de multiples publics pour évaluer l'intérêt de la télémédecine bucco-dentaire dans différents milieux. La pratique de la télémédecine bucco-dentaire doit permettre de lutter contre les inégalités d'accès aux soins et à la prévention pour la population française. Des intérêts se dégagent pour les patients, les professionnels de santé, les chirurgiens-dentistes et les institutions de santé, mais des améliorations sont nécessaires pour cadrer et pérenniser cette pratique. La profession doit prendre des décisions majeures et relancer les discussions pour que la France reste dans le peloton de tête à l'échelle internationale dans cette pratique.

Interprofessional survey on knowledge and attitudes of midwives regarding oral health, in France.

INTRODUCTION: Oral health is essential for psychosocial well-being and general health. For expectant mothers, pregnancy increases the risk of oral diseases and has a subsequent impact on the oral health of a child once born. Midwives are in charge of pregnancy monitoring, childbirth and newborns' first days of life. They could have an important role in prevention. However, limited studies evaluating the knowledge, attitudes and practices on oral health among midwives have been conducted in Europe. METHODS: We performed a cross-sectional study using a self-administered questionnaire. Two local midwifery associations sent out the questionnaire by email and social media networks to all registered midwives and practicing in the department of Herault (n=613), between April and May 2022. Statistical analyses on quantitative data and descriptive analyses of qualitative free-text responses were performed. RESULTS: In total, 167 midwives were included. We found a lack of knowledge on many oral health topics and this was stated as the main reason that only 29% of midwives provided oral health information to their patients. Only 30% of the midwives had a training module on oral health during their initial training, and less than half of them considered the training adequate. To improve their lack of knowledge, participants expressed a preference for digital communication methods for themselves; however, they favored in-person interaction for public interventions. CONCLUSIONS: This study showed a lack of training and knowledge about oral health among midwives and a lack of oral health discussion with expectant mothers who are a high-risk population for oral diseases.

Interprofessional Survey on Knowledge and Attitudes on Oral Health among Nurses in France.

PURPOSE: Healthcare professionals (HCPs) play a key role in improving the health literacy of patients. Since oral health is an essential part of overall health, the objective of this study was to assess the knowledge and attitudes about oral health among registered nurses. MATERIALS AND METHODS: A four-component questionnaire was used to assess the oral health training, oral health knowledge and attitudes of registered nurses. Participants were recruited from the city of Montpellier, France, and the surrounding area between May and June 2022 via e-mail and social media. RESULTS: In total, 416 responses were included in our study. Only 35.8% of nurses reported that they had received specific training on oral health and 24.3% had never advised patients to consult a dentist. Participants demonstrated good overall knowledge, but stated there were weaknesses in a variety of areas, such as oral health in children. The nurses proposed methods to improve understanding of the importance of oral health, namely by setting up training courses and better interdisciplinary collaboration. CONCLUSION: Our study showed that some aspects of oral health are not well understood by nurses. Initial training should be improved and supplemental training should be offered to improve the knowledge, attitude and practices of nurses in order to improve patient care.

Teledentistry and Forensic Odontology: Qualitative Study on the Capacity of Implementation.

The postmortem identification of people without an identity is performed either by using DNA, dental charts, or fingerprints (until advanced decomposition prevents their study). The lack of forensic dentists who can conduct identifications lead us to reflect on the use of digital technology in this area. The aim of this study was to validate the organizational capacity of using teledentistry for the identification of bodies in a forensic medicine department. A mixed observational study was conducted on 55 cases between July 2020 and February 2021 in the Forensic Medicine and Thanatology Department of Montpellier University Hospital. The protocol was structured in five steps: an initial interview with the agent (a forensic autopsy technician/caregiver specialized in forensic medicine), regarding the idea they had in terms of using telemedicine in their daily practice; agent training in the telemedicine system; realization of a clinical examination using an intra-oral camera by the agent; data analysis by a dental surgeon; final interview with the agent. The study was conducted on 55 subjects. The average age was 54 years old, with more than two-thirds of the patients being male (69%). The videos had an average duration of 29 min. There was an increase in visit duration when rigidity was high; this was also the case when there were many dental specificities in the oral cavity. The quality of the videos was either good or excellent. This study showed that remote identification could be considered as a new non-invasive identification tool. Many features were analyzed to create a training guide for forensic institutes.

Teledentistry from research to practice: a tale of nineteen countries.

Aim: The COVID-19 pandemic has accelerated teledentistry research with great interest reflected in the increasing number of publications. In many countries, teledentistry programs were established although not much is known about the extent of incorporating teledentistry into practice and healthcare systems. This study aimed to report on policies and strategies related to teledentistry practice as well as barriers and facilitators for this implementation in 19 countries. Methods: Data were presented per country about information and communication technology (ICT) infrastructure, income level, policies for health information system (HIS), eHealth and telemedicine. Researchers were selected based on their previous publications in teledentistry and were invited to report on the situation in their respective countries including Bosnia and Herzegovina, Canada, Chile, China, Egypt, Finland, France, Hong Kong SAR, Iran, Italy, Libya, Mexico, New Zealand, Nigeria, Qatar, Saudi Arabia, South Africa, United Kingdom, Zimbabwe. Results: Ten (52.6%) countries were high income, 11 (57.9%) had eHealth policies, 7 (36.8%) had HIS policies and 5 (26.3%) had telehealth policies. Six (31.6%) countries had policies or strategies for teledentistry and no teledentistry programs were reported in two countries. Teledentistry programs were incorporated into the healthcare systems at national (n = 5), intermediate (provincial) (n = 4) and local (n = 8) levels. These programs were established in three countries, piloted in 5 countries and informal in 9 countries. Conclusion: Despite the growth in teledentistry research during the COVID-19 pandemic, the use of teledentistry in daily clinical practice is still limited in most countries. Few countries have instituted teledentistry programs at national level. Laws, funding schemes and training are needed to support the incorporation of teledentistry into healthcare systems to institutionalize the practice of teledentistry. Mapping teledentistry practices in other countries and extending services to under-covered populations increases the benefit of teledentistry.

Dialogue with Key Stakeholders on Digital Technology for Oral Health: Meeting Report.

On September 7, 2022, the University of Montpellier in France hosted a meeting with digital oral health technology developers, Chief Dental Officers, policy makers, the World Health Organization, the International Telecommunication Union, and academia on digital oral health technologies.

Patient satisfaction with e-oral health care in rural and remote settings: a systematic review.

BACKGROUND: During the past decade e-oral health technology has been used to address the oral health care challenges in rural and remote settings. This review systematically evaluated the literature on patient satisfaction with e-oral health care in rural and remote communities. METHODS: The systematic review included interventional and observational studies published between 1946 and 2021, in the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Global Health. Patient satisfaction with received oral health care using self-reported measures, at any time after the intervention, was the main outcome of the review. The other primary outcomes were undesirable consequences of the health care (e-health or conventional) such as diagnostic error. The secondary outcomes considered were waiting time, number of visits, travel, and the cost of oral health care. Two independent researchers assessed the risk of bias using the ROBINS-I risk of bias assessment tool for non-randomized studies. RESULTS: Among 898 studies, 16 studies were included in the review. In most studies reporting patient satisfaction, all patients had shown willingness for teleconsultation for a dental problem and they were mostly satisfied due to saved travel time, saved working days, and prompt treatment onset. Most of the studies acknowledged teledentistry as a cost-effective and cost-saving method. Moreover, the teledentistry consultations showed diagnostic reliability and validity values comparable to conventional dental consultations. The majority of studies were considered level 4 and 3b, due to limited sample populations, analysis based on limited alternatives or costs, non-consistent sensitivity analysis, failure to appropriately control known confounders, and/or failure to carry out an appropriate follow-up of patients. CONCLUSION: Available evidence indicates that e-oral health is associated with higher patient satisfaction and has been found to be an effective and reliable method for patients in rural and remote areas. Therefore, in these areas, the use of e-oral health should be encouraged. However, methodological inconsistencies in the current evidence suggest the need for long-term cohort studies and clinical trials, as well as cost analysis on e-oral health in rural settings. SYSTEMATIC REVIEW REGISTRATION: The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42016039942.

Association of children's toothbrushing and fine motor skills: a cross-sectional study.

Fine motor skills (FMS) allow for the control and coordination of the distal musculature of hands and fingers, a skill required to brush teeth. The objective of this study was to investigate the association between FMS and toothbrushing efficacy. This cross-sectional study included 42 low-income Latino children aged 5 to 9 years from Pasto, Colombia. Toothbrushing efficacy was determined by the children's dental plaque Quigley-Hein Index (QH-I) mean-score difference from before and after toothbrushing. FMS were evaluated using the 5-15R parent evaluation, the spiral drawing Archimedes test, and a neurodevelopmental assessment of movements and prehension patterns during toothbrushing. A descriptive analysis was performed to assess the characteristics of FMS and children's toothbrushing, and a generalized linear model was used to determine associations between these skills and toothbrushing efficacy. Eighty-six percent of the children had at least one difficulty with FMS, and in 7%, they interfered with daily activities. Fourteen percent presented a moderate pattern in the Archimedes test, and 43% had inefficient prehension patterns. Toothbrushing reduced the QH-I by a mean of 1.45 (SD = 0.78-2.12) (p < 0.001). Toothbrushing efficacy was only significantly associated with age (mean-difference = -0.315, 95%CI: -0.481 to -0.148, p < 0.001). FMS and toothbrushing efficacy were not significantly associated. Other components of fine motor control should be analyzed to understand the kinetics of toothbrushing.

A national teledentistry study on the knowledge, attitudes, training and practices of private dentists.

Objectives: Nationally examine the self-perceived knowledge, attitudes and practices of TeleDentistry (TD) among dentists in private practice in France. Methods: A descriptive questionnaire-based survey was conducted nationwide from 10 November 2020 to 13 December 2020. The national scale survey was both anonymous and voluntary and was sent by the National Board of Dentists to 42,464 private dentists that were officially registered in France. The questionnaire included 36 questions divided into various sections: (i) general profile (gender, age range, and university, where respondents completed their dental studies), (ii) general knowledge of telemedicine, and (iii) familiarity with current regulations on telemedicine and activities that qualify as telemedicine. Results: Only 57.1% of dentists in private practice stated that they had never heard nor knew about TD (n=2,887). Only 1.5% (n=76) stated they had attended a training module on telemedicine and/or TD during their studies at university. Only 1.3% (n=26) of dentists who practised a TD activity stated that they knew about telemedicine regulations. Only 65.7% (n=2,020) of those who had never practised and 74.8% (n=1,485) who had practised TD acknowledged that they would like to practice TD. Conclusions: In conclusion, this study found a significant need for TD education and training as well as on regulations. It may be necessary in the future to ensure that all stakeholders in the field of dentistry work together to improve these two topics for dental practitioners. It is also worth noting that TD and telemedicine are public health tools and that they could provide inequitable access to medical care. However, TD must be implemented to decrease inequality and ensure it does not do the opposite.

The contribution of teledentistry in detecting tooth erosion in patients with eating disorders.

OBJECTIVE: The aim of this study was to demonstrate that including a teledentistry consultation in the standard care provided to patients in an eating disorder day hospital could be beneficial, notably for screening for particular pathologies and preventing dental erosion. METHODS: We included 50 patients from the eating disorders unit of the University Hospital of Montpellier, all of whom underwent a dental examination using asynchronous telemedicine. We recorded the data using teledentistry software for the medical file and an intraoral camera for the clinical videos. Remote diagnosis was performed using the Basic Erosive Wear Examination index. In addition, the participants completed a questionnaire to assess their risk factors for dental pathologies. RESULTS: We found dental erosion in 92% of the patients, and 50% had at least one tooth with BEWE 2 or 3 type erosion. CONCLUSIONS: Despite the fact that there can be wide variety within a group of individuals with similar risk factors, dental telemedicine could promote awareness within this at-risk population, as well as provide personalised prevention advice to each patient. Above all, it would make it possible to treat these patients' lesions at the earliest possible moment, thereby improving their outcomes.

Teledentistry and COVID-19: Be Mindful of Bogus "Good" Ideas!

The current health crisis has led to the emergence of new practices, new tools, and an increased use of digital health. Unfortunately, these are too often developed in a way that defies all logic or which has nothing to do with public health. Oral health professionals have been particularly affected during this crisis, and the use of digital health, and especially teledentistry, has been considered in many countries. However, the development of teledentistry is not free of bogus "good" ideas. It is time that teledentistry be adequately considered, while ensuring the quality of the medical procedure and with the aim of reducing inequalities in terms of access to oral healthcare and public health problems.

Applications of teledentistry in a French inmate population: A one-year observational study.

Teledentistry oral examination protocol was evaluated for one year at the Villeneuve-lès-Maguelone Correctional Facility. The aim of the study was to simplify the obligatory dental consultation protocol at the entrance visit for new detainees. 1051 detainees were enrolled and 651 of them (58.9%) accepted an oral examination by teledentistry throughout the entire year of 2018. Only 1 inmate did not need treatment and 88.06% of those who have been examined had at least one untreated cavitated carious lesion. Forty-four percent of people who received a teledentistry check-up were referred to a dentist with a dental emergency. The use of teledentistry at the entry visit in a detention facility may facilitate the oral health screening without wasting the dentist's time, and may allow an optimization of the inmate's oral healthcare.

Concordance study between regular face-to-face dental diagnosis and dental telediagnosis using fluorescence.

BACKGROUND: Teledentistry consultations are an effective way to increase access to care. Whether it be for a screening, referral or even an adapted treatment plan for a certain number of patients whose access to care is complicated, demonstrating the reliability of remote consultations is essential in allowing the technique to become generalised. AIM: This study aimed to determine if teledentistry consultations using fluorescence are of the same quality as regular consultations in the diagnosis of caries. METHODS: Patients were seen in consultation in the dental care centre at the Montpellier University Hospital (France) and in the centre at Kyushu Dental University Hospital (Japan). The protocol was broken down into three parts: the regular consultation, the recording of videos with the Soprocare camera and the remote consultation. The regular consultation and the remote consultation were blinded and carried out by two different dentists. The recording of videos was carried out by a third dentist. The carious diagnosis was based on the International Caries Detection and Assessment System: a clinical rating system for the detection and assessment of caries. RESULTS: One hundred and ninety-five patients met the predefined inclusion criteria. Most patients had at least one surface at stage 3 or higher (73%) with a higher proportion amongst French patients (81% compared to 66%). However, they had good dental hygiene, given that dental hygiene was only deemed unsatisfactory for 10.8% (19% for French patients and 2% for Japanese patients). The odontogram (presence/absence of each tooth) seemed to be correctly identified during the remote consultation (reinterpretation). Out of the 195 patients, 168 (86.2%) were identified without error. CONCLUSIONS: Teledentistry consultations can represent acceptable diagnostic performance with regard to the detection of dental caries. The Soprocare camera enables an early diagnosis of carious lesions with optimal efficiency. Several areas still need to be improved, however, so that the use of the camera during remote consultations is as coherent and effective as possible, especially with regard to the organisational aspects of remote consultations.

Performance of Fluorescence-based Systems in Early Caries Detection: A Public Health Issue.

AIM: Modern clinical caries management involves early stage caries diagnosis and should fit with dental health policy. The objective of this study was to achieve early caries detection in enamel and dentine with a laser-based system (DIAGNOdent™ pen) first and secondary with a new fluorescence intra-oral camera (Soprolife®). A visual inspection with a loupe was used as control. MATERIALS AND METHODS: Following the consolidated standards of reporting trials recommendations, 628 occlusal fissures were included for analysis. RESULTS: The sensitivity and specificity of both devices varied depending on the cutoff threshold of the caries score, and the ROC curve showed higher values for the Soprolife® than for DIAGNOdent™ pen. The values of the area under the curve decreased from 0.81 (Soprolife® in daylight) to 0.79 (Soprolife® in fluorescent mode) and 0.67 for DIAGNOdent™ pen. DIAGNOdent™ pen reproducibility (intra and inter-investigator) showed a wide dispersion, with many values scattered beyond the confidence limits (±2 SD), and the weighted kappa coefficient, which was quite low (0.58), confirmed this tendency. CONCLUSION: Caries prevalence in terms of public health policy is of interest and caries detection increased significantly when using an fluorescence-based intra-oral camera. CLINICAL SIGNIFICANCE: The clinical significance of these findings is that fluorescence could help improve caries diagnosis, reduce clinical misinterpretations, and finally benefit the patients.

Microbiota of interdental space of adolescents according to Risk of Caries: A cross-sectional study protocol.

Dental caries is a major oral disease resulting from a complex interaction between the commensal microbiota, host susceptibility (heredity, immunity, diseases, etc.) and environmental factors (diet, dental hygiene, etc.). To predict the patient's risk of new carious lesions or progression of existing lesions, the Caries Risk Assessment (CRA) takes account of clinical, biological and behavioural factors. Thus, the CRA can predict whether the patient is at high or low risk of developing caries. The practitioner can thus set up a follow-up adapted to the risk of the patient. However, although bacteria are the main etiological factor of carious lesions, the CRA does not consider bacterial quantification or just focus on the level of S. mutans in the saliva. As the majority of cavities are interproximal in adolescence, the aim of this trial is to identify and quantify the interdental microbiota of adolescents aged from 15 to 17 years with low or high carious risk. So, the quantification of new biomarkers associated with carious lesion could be added to the CRA to improve it.
