The purpose of this study was to assess the impact, and students' and teachers' perceptions, of using smartphones as clickers during formal lectures. This was an observational study based on a qualitative analysis of semi-structured interviews. Forty French dental students received conventional lectures, and 40 additionally used the Socrative® digital tool to answer several questions during the session. Thematic analysis makes it possible to state that students were bored by, and unwilling to take part in, conventional lectures. The use of real-time, smartphone-based questions helped them to stay focused and share opinions with their classmates. Teachers also found the lecture livelier and the students more involved thanks to the immediate feedback. The results of this study imply that using smartphones as clickers may simplify the use of clickers, encourage students to participate and increase student-teacher interaction.

Objective: Epidermolysis bullosa (EB) is a rare genetic mucocutaneous disorder characterized by epithelial fragility leading to blister formation on skin and mucous membranes with even minor mechanical trauma. Most EB oral health publications give fragmented information, focusing on only one oral health aspect or one EB type. The aim of this study was to expand the knowledge of the overall oral health status of individuals with dystrophic, junctional, and simplex EB. Method and materials: A comparative multicenter study, including a control group, and based on questionnaires and clinical examinations, was undertaken in three EB expert centers. Results: Most EB (90.2%) participants brushed their teeth at least once a day despite the pain. The prevalence of enamel defects and caries experience did not differ between the 42 EB participants and the 42 age-/sex-matched healthy controls. Gingival inflammation unrelated to dental plaque accumulation was found in EB participants. Blisters, erythema, and erosion/ulceration mainly involved gingiva, buccal mucosa, lips, and palate, with different topographic patterns according to EB type. EB patients whatever the age showed a similar lesion distribution. Simplex and dystrophic EB patients under 12 years old displayed higher lesion severity than junctional EB ones. Only dystrophic type exhibited microstomia and ankyloglossia. Conclusion: Oral health status seemed to benefit from a close collaboration between dental practitioner and dermatologist, and from regular dental examination, starting at a young age and with a focus on prevention. The new appreciation of oral health involvement highlighted by this study is essential for EB patients care, regarding comorbidities and quality of life. [ABSTRACT FROM AUTHOR]

Introduction: Narrative medicine is a novel approach aimed at attending to the socio‐emotional aspects of illness and care. Parallel charts represent one of the tools of narrative medicine and are brief accounts of care in which practitioners can express their feelings and emotions towards patients and treatments. They are, therefore, intended to collect practitioners' feedback in the form of "narrative" tools to encourage reflection. Materials and Methods: This is a single‐centre observational pilot study comprising the setting up and analysis of parallel charts in two classes of 5th and 6th year students in a Paediatric Dentistry Department in France. Forty‐four students completed 126 parallel charts. A qualitative, thematic, analysis was conducted and the charts were also classified according to the three types of description of illness made by Arthur Kleinman. Results: This work showed that dental students mainly compiled parallel charts from a disease‐centred perspective. The qualitative analysis identified the various themes addressed by the student: relationship with patients and managing children's anxiety, student stress, relationship with the environment or with lecturers. Conclusion: The qualitative analysis highlighted the usefulness of compiling parallel charts by the students to allow them to express both positive and negative feelings, and thus to adopt a self‐evaluative approach regarding their practices based on emotional impact. Parallel charts may improve patient‐practitioner relationship, but more extensive studies over longer periods of time need to be undertaken. [ABSTRACT FROM AUTHOR]

A 12‐year‐old girl presented to the Department of Paediatric Dentistry of the Toulouse University Hospital 10 days after a facial injury, complaining of persistent pain and halitosis. Previous examinations only reported trauma of the upper incisors. Further clinical exploration showed an 8 cm laceration of the oral mucosa in the lower labial sulcus, 1.5 cm inferior to the gingival margin and exposing the symphyseal bone. The diagnosis of mental protuberance degloving was established. The treatment consisted of debridement of the wound, removal of the necrotic tissue, multiple plane sutures and antibiotics. Complete healing of the wound with no sensory deficit was achieved. Mental degloving injuries occur when a shearing force is applied to the soft tissues overlying the chin, stripping them from the labial bone. This type of wound is rare and can go undetected if a meticulous oral examination is not performed. Early management is essential so healing is not compromised. [ABSTRACT FROM AUTHOR]

Introduction: Dental education emphasises the acquisition of technical skills. Recent advances in 3D printing technologies have enabled the emergence of new educational tools usable in hands‐on work sessions. The possibility to print 3D models from CT scans of patients is now available to dental practitioners. The aim of this study was to develop and evaluate a 3D printed model for paediatric dentistry training and compare it to the reference model used in our faculty. Materials and Method: 3D models were obtained by modifying and printing the CT scan of a young patient using the Voco® Solflex 350 3D® printer and Voco® V‐print resin. Thirty‐four students were asked to perform a pulpotomy and preparation for a stainless steel paediatric crown on tooth 85 on both the 3D printed model and the industrial model (Frasaco®), and then to answer a questionnaire. The data were analysed using R software. Result: Both models obtained high scores. The learning potential and its applicability to clinical practice showed no statistically significant difference. Although the colour and the simulation of the proximal area disturbed the students (P = 0.009), the 3D models were seen as a good idea (P = 0.012). When it came to model design, the students appreciated the simulation of caries on 3D models (P = 0.0001) and considered the use 3D of models as a more realistic experience (P = 0.017). Discussion: Although this study has some limitations (number of participants, choice of the models to be compared), it constitutes the first attempt to compare students' perception of 3D and series models. It shows that 3D technology makes it possible to obtain models of similar quality while offering a more realistic experience. Conclusion: There are still many ways in which these models could be improved. For example, modifying the quality of resins could improve the milling sensation, and the design could be improved to achieve better contact points. Nevertheless, these 3D models offer the possibility to give the patient a more central place in the education of future practitioners. [ABSTRACT FROM AUTHOR]

Purpose Obstructive sleep apnea (OSA) has been described as a common sleep respiratory disorder. Its prevalence in the adult population has been reported to be high, varying from 3% to 28%. Dental practitioners play a key role in the treatment of this disease, using tailor-made mandibular advancement devices (MADs). This pilot study assessed the efficacy and compliance of a custom-fitted thermoplastic MAD for the treatment of moderate to severe OSA syndrome. Materials and Methods In this open study without a control group, OSA syndrome sufferers were enrolled by four centers. One specific MAD was custom fitted to the patients. Polysomnography, Epworth, and snoring scales were administered from inclusion to 45 days postinclusion. Results The study population consisted of 33 men and 8 women; 35 patients completed the study. Patient response was high with 69% of them considered as responders, and 60% showing a complete response. Also, 77.3% of patients with moderate OSA syndrome presented a complete response. An improvement was observed in the apnea hypopnea index, which decreased from 34.1 ± 18.9 to 12.8 ± 14.1. The Epworth Sleepiness Scale score, snoring, and quality of sleep scores decreased with the device ( p < 0.0001). Compliance rates were high, with patients wearing the device 6.5 nights a week. Side effects and patient complaints were minor and transient. Conclusion This custom-fitted MAD improved respiratory and somnolence parameters, with response rates similar to those published in the literature with other devices. [ABSTRACT FROM AUTHOR]
