Improving evidence on evaluating the acceptance of the cognitively impaired is required to improve the technology development process so that it can be translated into an improved patient experience and adherence. Although the study was specifically focused on teledentistry, the approach described in this study could be adapted to other forms of teleconsultation.

Purpose In France, all incarcerated prisoners are required to undergo a dental examination (Ministère de la santé et de la protection sociale, 2004 and Ministère de la justice, 2004). However, only one in two prisoners benefits from this oral health check-up. Oral teleconsultation could improve the quality of oral care in prisons. The paper aims to discuss these issues. Design/methodology/approach The focus of this study was therefore to apply oral teleconsultation as an experiment. Using an oral teleconsultation system, a dentist and a nurse were separately asked to give patients a score, according to how urgently their dental issue needed to be treated. This score will henceforth be referred to as the "dental emergency scores given". Findings The separate dental emergency scores given by the dentist and the nurse were compared and the results demonstrate the following: - 36.7 per cent (11) of the two scores were equal - 53.3 per cent (16) of the two scores differed by 1 point - 10 per cent (3) of the two scores differed by 2 points. The average score of the nurse was 2.23 and that of the dentist was 2.13. The small disparity should not obscure the fact that 63 per cent of the diagnoses turned out to be incorrect. Practical implications Dental care could easily be improved with oral teleconsultation as a care plan could be developed for each patient. Social implications The condition of one's dental health is, of course, very important for general health, but it also affects social aspects. Good oral hygiene and health are very important when looking for a job after having been released from prison. Originality/value This is the first study on oral teleconsultation in prisons. Dental care is rarely studied on prisoners. Telemedicine in dentistry is just beginning all over the world. This study is the first step of an extensive project in the University Hospital of Montpellier and the Villeneuve-les-Maguelone prison.

Adolescence is closely associated with a high risk of caries. The identification of specific bacteria in an oral microniche, the interdental space of the molars, according to carious risk can facilitate the prediction of future caries and the anticipation of the progression or stabilization of caries in adolescents. A cross-sectional clinical study according to the bacteriological criteria of interdental healthy adolescents and carious risk factors—low and high—using a real-time polymerase chain reaction technique was conducted. The presence of 26 oral pathogens from the interdental microbiota of 50 adolescents aged 15 to 17 years were qualitatively and quantitatively analyzed. Bacteria known to be cariogenic (Bifidobacterium dentium, Lactobacillus spp., Rothia dentocariosa, Streptococcus cristatus, Streptococcus mutans, Streptococcus salivarius, Streptococcus sobrinus, and Streptococcus wiggsiae) did not present differences in abundance according to carious risk. Periodontal bacteria from the red complex are positively correlated with carious risk. However, only 3 bacteria—S. sobrinus, E corrodens and T. forsythia—presented a significant increase in the highest group. Estimating the risk of caries associated with bacterial factors in interdental sites of molars in adolescents contributes to the better definition of carious risk status, periodicity and intensity of diagnostic, prevention and restorative services.

Proper treatment of dental caries demands detection of carious lesions at an early stage and a minimal invasive cavity preparation to preserve the maximum tooth structure. Various devices use fluorescence for caries detection via recording the red fluorescence generated by dentin caries under illumination. The aim of this study was to evaluate the porphyrin and pentosidine involvement in the red fluorescence observed in enamel and dentin caries when illuminated with the Soprolife® camera (Sopro, Acteon Group, La Ciotat, France) and Vistacam® camera (Dürr Dental AG, Bietigheim-Bissingen, Germany). Three techniques were used: single photon fluorescence spectroscopy, micro-Raman spectroscopy, and color analysis with ImajeJ software. Cross-sections of human teeth, scored from 0–6 with the International Caries Detection and Assessment System (ICDAS), were examined by fluorescence microscopy. Teeth spectra of each ICDAS score were compared with those of protoporphyrin IX (PpIX), porphyrin I, and pentosidine solutions. A specific confocal Raman microscopy analysis was realized and a Red–Green–Blue model analysis of Soprolife® images was performed using ImageJ software to compare the color variations on ICDAS score 1 and 2. Fluorescence spectroscopy and micro-Raman spectroscopy revealed the presence of PpIX in carious enamel and dentin. The clinical relevance of this experimentation was that the increased knowledge of the fluorescence aids for caries detection could improve the preventive approach, thus reducing the operative one.

Objective A large number of digital tools supporting students have emerged over recent years which are encouraged in tutoring. A study conducted at the University of Montpellier (France) among 3rd, 4th, and 5th year dentistry students aimed primarily to identify the type of pedagogical support the students preferred according to their discipline. The secondary aim was to evaluate the student satisfaction after establishing a new pedagogical support. Materials and Methods A total of 165 questionnaires were completed. The main questions concerned pedagogical use of information technology and multimedia tools, choice of dentistry disciplines most justifying their use, and pedagogical gaps in these disciplines. Next, a program of pedagogical videos was developed for the most corresponding discipline. A satisfaction survey was finally conducted. Results Nearly 95.7% of students found online classes and E-learning via the virtual learning environment useful, with the most requested type being video. Demand was stronger in conservative dentistry and endodontics (27%), prosthetics (19%), and periodontology (18%). The most apprehended disciplines were endodontics in the 3rd year, endodontics and prosthetics in the 4th year, and prosthetics in the 5th year. Regarding satisfaction, 100% of students appreciated these videos and 99.4% considered they fulfilled expectations. Conclusion All students requested videos, especially for clinical subjects such as endodontics. With digital technology, our world is experiencing a technological revolution resulting in many daily life changes. With students evolving in a digitally saturated society, our ways of learning and teaching need rethinking. Digital technology can help improve learning effectiveness and develop pedagogical practices more adapted to today's students.

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.

BackgroundIndividuals living in rural and remote settings face oral health problems and access-to-care barriers due to the shortage of oral health care providers in these areas, geographic remoteness, lack of appropriate infrastructure and lower socio-economic status. E-Oral Health technology could mitigate these barriers by providing the delivery of some aspects of health care and exchange of information across geographic distances. This review will systematically evaluate the literature on patient satisfaction with received E-Oral Health care in rural and remote communities.MethodsThis systematic review will include interventional and observational studies in which E-Oral Health technology is used as an intervention in rural and remote communities of any country worldwide. Conventional oral health care will be used as a comparator when provided. Patient satisfaction with received E-Oral Health care will be considered as a primary outcome for this review. Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Global Health will be searched using a comprehensive search strategy. Two review authors will independently screen results to identify potentially eligible studies and independently extract the data from the included studies. A third author will resolve any discrepancies between reviewers. Two independent researchers will assess the risk of bias and the Grading of Recommendations Assessment, Development, and Evaluation.DiscussionThe potential implications and benefits of E-Oral Health care can inform policymakers and health care professionals to take advantage of this technology to address health care challenges in these areas.Systematic review registrationPROSPERO CRD42016039942.Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-017-0550-3) contains supplementary material, which is available to authorized users.

Objectives:The purpose of this study was to identify the major sources of perceived stress and their relation to a student satisfaction questionnaire about the curriculum and the pedagogy among French dental students.Materials and Methods:All dental students (n = 178) from years 4 to 6 at the University of Montpellier (France) participated in this exploratory survey. In spring 2016, a 3-part questionnaire was distributed during clinical sessions: the first part asked about sociodemographic and living conditions, the second part aimed to assess the students' perceived stress (Dental Environmental Stress questionnaire), and the third part was a satisfaction questionnaire exploring the clinical organization and the teaching methodologies (Student Course Experience Questionnaire). A Spearman's correlation test and a principal component analysis were used to assess the relation between the variables of the questionnaire.Results:The response rate was 99.4%. The most stressful items were “the number of tasks to be performed during clinical practice,” “the waiting time before opinion from teachers,” and “the administrative part and computer problems.” Fifty-four percent of the students claimed to be satisfied with their studies, showing a score of seven or higher. There was a negative correlation between the level of student satisfaction and the level of perceived stress.Conclusion:Although most of the students were globally satisfied with their curriculum, this study highlighted dysfunctions in the clinical education with a level of stress correlated with the student's dissatisfaction. Most of all, students found that examinations were too stressful and that the clinical requested task quotas were overestimated.
