Comparative Evaluation of Digital Cephalometric Tracing Applications on Mobile Devices and Manual Tracing.

BACKGROUND Cephalometric radiography evaluates facial skeleton development and aids in diagnosis and treatment phases (pre and post) in orthodontics. This study aimed to compare digital cephalometric tracing using a smartphone application (App), a tablet-based platform, and manual tracing in 30 orthodontic patients. MATERIAL AND METHODS Thirty orthodontic pretreatment, criteria based, lateral cephalometric radiographs were analyzed/grouped for Steiner analysis parameters (5 skeletal, 3 dentals, 1 soft tissue) by 3 tracing methods [manual - group (Gp M), smartphone (Android - OS9) - Gp S, tablet (Apple - IOS13) - Gp T) after mandatory standardization/calibration. Measurements include 5 angular (SNA, SNB, ANB, SNMPA, SNOP), 3 linear U1NA, L1NB, U1L1, and 1 soft tissue (S line) (millimeters and degrees). Inter-examiner rating was determined using Dahlberg's test. After normality distribution testing (Shapiro-Wilk), data were analyzed using one-way analysis of variance (ANOVA) for group differences. Homogeneity of variance was verified using the Levene test. Differences were determined on probability value of (p≤0.05). RESULTS The results showed that Steiner's analysis parameters were similar in all groups with homogenous variances. Highest differences in mean values were found for L1NB, U1L1, and S line measurement, with higher values being observed in Gp S tracings. However, these differences were not statistically significant (p≤0.05). All parameters, irrespective of being measured in either degrees or millimeters, had means comparable to each other. CONCLUSIONS Smartphone and tablet-based applications produced tracings that were comparable and reliable when compared to conventional manual tracings. Standardization of images, processing, printing, and calibration of devices is important to achieve good results.

Awake bruxism report in a population of dental students with and without ecological momentary assessment monitorization-A randomised trial.

OBJECTIVE: The Ecological Momentary Assessment (EMA) concept was the basis for developing a smartphone application for the real-time report of awake bruxism (AB) activities. The aim of this study was to assess the effects of the EMA with a randomised controlled trial designed to compare the frequency of AB reported in two separate single observation points between a group of students monitored over time with an EMA smartphone application and a non-EMA monitored group. METHODS: Sixty-four (N = 64) dental students (22.3 YO [±2.6]; 52F; 12 M) answered the Oral Behaviour Checklist (OBC-1) and were randomised into an EMA-group (EG) and control group (CG). EG were monitored with a smartphone application for AB report during seven consecutive days and completed three EMA monitoring periods (EMA-1, 2 and 3) at one-month intervals. After the third period (EMA-3), both EG and CG answered again the OBC (OBC-2). Descriptive statistics were performed to characterise the sample. Pearson's chi-squared test, Fixer Exact test and post hoc Z test with Bonferroni correction were performed. The study hypothesis was that EMA could influence the AB reported by the participants because it implies an increase in the awareness, self-recognition, and self-control of bruxism behaviours. The level of significance was set at p < .05. RESULT: The percentage of participants who changed the report of the activity of clenching their teeth while awake between OBC-1 and OBC-2 was significantly higher among participants in EG, when compared to CG (p = .027). For all other behaviours reported the within- and between-group differences from OBC-1 to OBC-2 were not significant. Clenching and bracing were the most frequently reported, whilst grinding was the less frequent behaviour. CONCLUSION: A smartphone-based EMA approach demonstrated be useful to monitor AB over time, increasing individual's awareness, particularly to bracing and clenching behaviours.

Benefits of the combination of digital and analogic tools as a strategy to control possible awake bruxism: A randomised clinical trial.

BACKGROUND: Awake Bruxism (AB) management includes cognitive and behavioural changes. Digital and analogic tools can be used to remind the individual to control/avoid AB behaviours. However, no study addressed both tools together. OBJECTIVE: To compare the efficacy of the combination of digital (smartphone application) and analogic (adhesive reminders) tools versus digital tool alone for AB management. METHODS: Seventy-two individuals diagnosed with probable AB were divided into 3 groups: Group 1 (n = 24), used both digital and analogic tools during 30 days; Group 2 (n = 24), used only a digital tool during 30 days and Group 3 (n = 24), used only a digital tool for the first 15 days and then added the analogic tool for 15 days. The AB frequency was measured in real-time with a smartphone app, which sent alerts asking the individuals if they were doing any AB behaviours (bracing, teeth contact, clenching or grinding). Groups were compared using one-way ANOVA and before-after adding an analogic tool (group 3) by paired t-test, considering α = 0.05. RESULTS: All groups showed a decrease in AB behaviours at the end of the evaluation period. Group 1 (digital and analogic tools) showed the lowest average of AB behaviours among all groups; however, statistically significant differences were found only for the comparison between groups 1 and 2. In group 3, a significantly greater reduction in AB behaviours was found after combining both approaches. CONCLUSION: The combination of digital and analogic tools showed the greatest reduction of AB frequency and can be recommended for AB control.

The International Association of Dental Traumatology (IADT) and the Academy for Sports Dentistry (ASD) guidelines for prevention of traumatic dental injuries: Part 8: ToothSOS app.

The Guidelines for Prevention of Traumatic Dental Injuries were reviewed and approved by the Board of Directors of the International Association of Dental Traumatology (IADT) and the Academy for Sports Dentistry (ASD).

Electronic oral health surveillance system for Egyptian preschoolers using District Health Information System (DHIS2): design description and time motion study.

BACKGROUND: Early childhood caries (ECC) is a major global health issue affecting millions of children. Mitigating this problem requires up-to-date information from reliable surveillance systems. This enables evidence-based decision-making to devise oral health policies. The World Health Organization (WHO) advocates the adoption of mobile technologies in oral disease surveillance because of their efficiency and ease of application. The study describes developing an electronic, oral health surveillance system (EOHSS) for preschoolers in Egypt, using the District Health Information System (DHIS2) open-source platform along with its Android App, and assesses its feasibility in data acquisition. METHODS: The DHIS2 Server was configured for the DHIS2 Tracker Android Capture App to allow individual-level data entry. The EOHSS indicators were selected in line with the WHO Action Plan 2030. Two modalities for the EOHSS were developed based on clinical data capture: face-to-face and tele/asynchronous. Eight dentists in the pilot team collected 214 events using modality-specific electronic devices. The pilot's team's feedback was obtained regarding the EOHSS's feasibility in collecting data, and a time-motion study was conducted to assess workflow over two weeks. Independent t-test and Statistical Process Control techniques were used for data analysis. RESULTS: The pilot team reported positive feedback on the structure of the EOHSS. Workflow adaptations were made to prioritize surveillance tasks by collecting data from caregivers before acquiring clinical data from children to improve work efficiency. A shorter data capture time was required during face-to-face modality (4.2 ± 0.7 min) compared to telemodality (5.1 ± 0.9 min), p < 0.001). The acquisition of clinical data accounted for 16.9% and 21.1% of the time needed for both modalities, respectively. The time required by the face-to-face modality showed random variation, and the tele-modality tasks showed a reduced time trend to perform tasks. CONCLUSIONS: The DHIS2 provides a feasible solution for developing electronic, oral health surveillance systems. The one-minute difference in data capture time in telemodality compared to face-to-face indicates that despite being slightly more time-consuming, telemodality still shows promise for remote oral health assessments that is particularly valuable in areas with limited access to dental professionals, potentially expanding the reach of oral health screening programs.

Awareness and usage of mobile applications as an orthodontic diagnostic tool among Croatian orthodontic clinicians.

OBJECTIVE: To assess the impact of gender and orthodontic qualification length on the awareness, knowledge and usage of orthodontic diagnostic mobile applications, non-diagnostic mobile applications and social media platforms among orthodontic clinicians. DESIGN: Cross-sectional questionnaire-based study. SETTING: The Republic of Croatia. PARTICIPANTS: A total of 92 orthodontic specialists, members of the Croatian Dental Chamber. METHODS: This study was conducted using a questionnaire distributed via email to orthodontic clinicians between May and July 2022. RESULTS: In total, 92 respondents were divided into groups according to sex and median orthodontic qualification length: more recently qualified (MRQ) with ⩽12 years; and longer qualified (LQ) with >12 years. Nearly one-third of respondents did not have any prior knowledge of mobile applications used as an orthodontic diagnostic tool. MRQ respondents were more interested in using mobile apps as opposed to computer software for digital analysis (P < 0.05). This interest was in a negative correlation with orthodontic qualification length (P < 0.01) and was more prevalent among female respondents (P < 0.001). About one-third (32.6%) of respondents did not use non-diagnostic mobile applications and 44.6% did not use social media platforms. Nearly two-thirds (62%) of the respondents did not promote their work through social media. Male respondents and LQ promoted their work more frequently than others (P < 0.05). The usage of other mobile applications was in a positive correlation with the knowledge and awareness of orthodontic mobile applications (P < 0.05). CONCLUSION: Orthodontic clinicians lacked knowledge, awareness and the usage of orthodontic diagnostic mobile applications according to sex and orthodontic qualification length. One-third used non-diagnostic mobile applications and less than half used social platforms in daily clinical work.

A novel wide scale well-baby clinic mobile application: an Egyptian pilot study.

BACKGROUND: Utilization of under 5-year-old child healthcare services in Egypt is considered low, the highest proportion of well-baby visits is mainly for immunization in the first 2 years of age. Mobile health (mHealth) interventions have the potential to be a useful and low-cost way to disseminate information about proper nutrition, can be used to monitor children's growth using the official charts of World Health Organization, can also help in accessing vaccine-related information and schedules. OBJECTIVES: To assess needs and requirements for a new comprehensive well-baby clinic mobile application (app) covering well-baby clinic service components. Thereafter, to develop the app prototype and validate it. METHODS: This study was conducted in four phases: User requirements, development, validation and usage. In user requirement phase, the need for the new app was assessed by performing literature review, market app research and an online survey. In development phase, we developed the novel well-baby clinic app that constituted all well-baby clinic services for children's health monitoring relying on evidence-based information and honoring data safety. In validation phase, after a series of testing, the app was validated using Mobile app rating scale (MARS) by public health and pediatrics consultants to assess its quality. Finally, the app was launched and made available to the public on Android platform. RESULTS: Sehhat Tefly app was developed based on the demands and requirements of mothers of under 5-year-old children. The app constituted caregiver, child information and seven service elements: physical growth, developmental milestones, immunizations, nutrition, teething, safety & emergency measures and report. The app quality mean was rated 3.7 out of 5 by the panel of experts. The app was downloaded 1445 times in a 4 month period. CONCLUSIONS: Sehhat Tefly app can meet the need for a free, easy and accessible tool for caregivers to track the progress of children's development and wellbeing. It can also provide advice for referral to physician consultation in case of deviation from normal measures.

Mobile educational tool based on augmented reality technology for tooth carving: results of a prospective cohort study.

BACKGROUND: Augmented reality (AR) technology has been shown to be effective in displaying information and presenting three-dimensional objects. Although AR applications are commonly used by learners via mobile devices, plastic models or two-dimensional images are still commonly used in tooth carving practice. Learners practicing tooth carving face a challenge due to the three-dimensional features of teeth as there is a lack of tools available that provide sequential guidance. In this study, we developed an AR-based tooth carving practice tool (AR-TCPT) and compared it to a plastic model to evaluate its potential as a practice tool as well as its user experience. METHODS: To model tooth carving, we created a three-dimensional object from sequential steps that included the maxillary canines and maxillary first premolars (16 steps), mandibular first premolars (13 steps), and mandibular first molars (14 steps). Image markers, created using Photoshop software, were assigned to each tooth. An AR-based mobile application was developed using the Unity engine. For tooth carving, 52 participants were randomly assigned to a control group (n = 26; using a plastic tooth model) or an experimental group (n = 26; using the AR-TCPT). User experience was evaluated using a 22-item questionnaire. Data were comparatively analyzed using the nonparametric Mann-Whitney U test via the SPSS program. RESULTS: The AR-TCPT detects image markers with the mobile device camera and displays three-dimensional objects for tooth fragmentation. Users can manipulate the device to view each step or examine the shape of a tooth. The results of the user experience survey revealed that the AR-TCPT experimental group scored significantly higher in tooth carving experience compared with the control group that used the plastic model. CONCLUSION: Compared with the conventional plastic model, the AR-TCPT provided a better user experience for tooth carving. The tool is highly accessible as it is designed to be used on mobile devices by users. Further studies are required to determine the educational impact of the AR-TCTP on quantitative scoring of carved teeth as well as individual user's carving abilities.

Effectiveness of a smartphone application on dental anxiety in adolescents: A randomized controlled trial.

BACKGROUND: Dental anxiety is a common issue among adolescents. Despite the use of smartphones being an important part of their daily lives, only a few digital-based interventions for dental anxiety have been tested in randomized controlled trials (RCT). AIM: The aim of this study was to evaluate a new smartphone application (App) named FALE, which was designed to demonstrate interest from the dentist to adolescent and to reduce dental anxiety. DESIGN: This is a RCT in which 184 adolescents aged 10-19 years were randomly allocated into the intervention group (IG) or the control group (CG). The intervention was applied in the waiting room before the consultation at a dental clinic. The IG answered the FALE, which contained 14 questions-of which the first and last questions addressed anxiety, whereas the CG answered the question about anxiety twice with an interval between them. RESULTS: There was a significant difference in the distribution of anxiety rating frequencies before and after the intervention period in both groups. For the IG, there was a reduction in anxiety after the intervention of 16.29%, and, in the CG, a reduction of 2.2% (p < .001). CONCLUSION: The FALE App effectively reduced dental anxiety before the appointment.

Aligning orthodontic education: Investigating the use of a digital app to improve the performance in managing orthodontic problems.

INTRODUCTION: General dentists are qualified to manage orthodontic emergencies within their scope of practice. This may involve advice, hands-on intervention or referral to a specialist orthodontist. This study aimed to assess the effect of an orthodontic app on dental undergraduates' ability to manage common orthodontic issues. In addition, this study aimed to determine the confidence of dental students in finding information related to orthodontic emergencies (CFI) as well as their confidence in managing orthodontic emergencies (CMOE). MATERIALS AND METHODS: Students were randomised into one-of-three groups, an app group, an internet group and a closed-book, exam-style group. All participants self-reported their CFI and CMOE. Following this, all participants were asked to complete a multiple-choice question (MCQ) paper based on clinical orthodontic scenarios. In addition, the app group were instructed to complete an app usability questionnaire (MAUQ). RESULTS: Approximately, 91.40% of students (n = 84) had not received clinical training in managing orthodontic emergencies, and 97.85% (n = 91) had not managed an orthodontic emergency clinically within the last 6 months of their training. The mean score for CFI was 0.10 out of 1.0 (SD 0.11) and CMOE was 0.28 out of 1.0 (SD 0.23). Statistically significant better MCQ scores were found in the app group, and no statistically significant difference was found between the internet and exam-style group. CONCLUSIONS: This study is the first to consider the use of an orthodontic app to aid in the management of orthodontic issues. It has practical implications for how mobile apps can aid in learning and can be incorporated into the wider dental field.

Orthodontic apps: An assessment of content accuracy and validity.

OBJECTIVE: To assess the content accuracy of orthodontic treatment information in patient-focused apps. DESIGN: A cross-sectional review study. SETTING: Orthodontic apps available on the UK Android and Apple App Stores. METHODS: Apps identified in a previous research study and those identified via a questionnaire of specialist orthodontists were assessed for accuracy of content utilising an evidence-based checklist. The checklist covered five main orthodontically relevant themes and 32 codes with respective items. RESULTS: The accuracy of information content for 16 patient-focused apps was assessed. Eight apps provided information related to orthodontic treatment and handling emergencies. Five apps were reminder apps and a small number (n = 3) contained games and timers for toothbrushing and aligners. With regard to the accuracy of information content, only two apps contained information across all five themes of the evidence-based checklist. Only one app received a score of 'fair - excellent' under the oral hygiene theme; interestingly, this app was the most commonly used patient-focused app. Eight apps containing orthodontic treatment information scored poorly as they had inaccurate information on handling emergency situations. None of the apps were deemed excellent with regard to accuracy of information content. CONCLUSION: The orthodontic mobile apps assessed in this study mostly contained information of poor accuracy. Therefore, there is a need for high-quality apps with credible information supported by evidence to be developed.

The awareness and usage of orthodontic apps and social media by orthodontists in the UK: A questionnaire-based study.

OBJECTIVE: To assess the awareness and usage of mobile apps and social media among orthodontic clinicians to support patients with orthodontic treatment, support the professional development of orthodontists, and identify any relevant apps and social media platforms currently recommended to patients. DESIGN: Cross-sectional questionnaire-based study. SETTING: United Kingdom. METHODS: A questionnaire was developed and distributed to members of the British Orthodontic Society (BOS). To increase the response rate, the questionnaire was circulated at three time points between January and March 2020. RESULTS: A total of 149 orthodontists responded to the questionnaire (15% response rate) with 113 orthodontists completing all questions (11.4%). Of those who answered, 81% (n = 111) had been qualified for >10 years, 35% worked in practice (n = 48), 34% worked in a hospital (n = 47) and 26% worked in both hospital and practice (n = 36). The results indicated that 20% of clinicians (n = 22) used apps to support patients and 33% (n = 37) reported using apps for professional purposes. Brush DJ appeared to be the most popular patient focused app (39%, n = 18) whereas the IOTN (17%, n = 8), Invisalign (17%, n = 8) and Dental Monitoring apps (9%, n = 4) were the most popular clinician-focused apps. With regard to social media, 53% (n = 60) of respondents reported that they used social media to communicate generic orthodontic information and promote their practice to patients. The most commonly used social media platforms were Facebook and Instagram. Of respondents, 96% expressed a willingness to recommend an evidence-based mobile app to patients if available, and 88% were willing to recommend an evidence-based social media platform. CONCLUSIONS: Orthodontic clinicians are utilising mobile apps and social media to support both patients and their own professional development. There is a willingness to increase the use of evidence-based platforms and apps to support patients.

Relationship between Behavior and Periodontal Health Self-Perception in Diabetic and Non-Diabetic Patients from Transylvania, Romania-A Self-Report Study, including The Desire to Use a Mobile App for Oral Care Improvements.

The study aimed to assess self-reported symptoms of periodontal disease (gingival bleeding, tooth mobility and halitosis) among diabetic and non-diabetic patients from Transylvania, Romania. Using statistical analysis methods, correlation between the aforementioned symptoms and diet, oral hygiene habits, stress, physical activity, and BMI (body mass index) were researched. Another secondary objective was to assess the impact of self-reported oral health, aesthetics, and halitosis on their life. Patients' willingness to use a mobile app for generating awareness of oro-dental complications, improving their knowledge of oro-dental health, and reminding them to visit the dentist based on an awareness-raising function, was also assessed. Methods: The study was based on an original self-administered questionnaire, applied to 182 subjects, in an unselected, randomized manner. A total of 110 questionnaires were applied in two dental offices and 72 questionnaires were applied in a public clinic for diabetic patients from Cluj-Napoca, Romania. Results: Warning signs and symptoms relevant to periodontal disease were identified by respondents, having statistically significant associations with the declared oral health-care habits, including interdental aids, vicious habits (nail biting, bruxism), etc. Some of these periodontal signs could be correlated with a certain lifestyle, such as the perceived stress, smoking status, practicing maintenance sports, and alcohol consumption. A total of 66% of the non-diabetics and 68% of the diabetics of the surveyed subjects consider a software application for generating awareness of oro-dental complications useful, and are willing to pay around EUR 6 for it. Conclusions: Having a medical condition such as diabetes makes patients pay more attention to dental health compared with non-diabetic patients. Patients expressed their desire to use a software application to help them to be aware of their condition and for improving their self-report capabilities, including their oral-health-related status.

Does using mobile applications and social media-based interventions induce beneficial behavioral changes among orthodontic patients?

DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs) and controlled clinical trials (CCTs). The protocol of the study was registered on the International Prospective Register of Systematic Reviews (PROSPERO: CRD42019157298). DATA SOURCES: Seven electronic databases (MEDLINE, Web of Science Core Collection, Unpublished Clinical Trials accessed through clinicaltrials.gov, Embase, LILACS, ProQuest Database, The Cochrane Library) were searched. Additionally, the reference lists of the included studies were hand searched. STUDY SELECTION: Clinical trials (RCT and CCT) that assessed the impact of the interventional use of mobile applications and social media among orthodontic patients were included. The review question was defined in PICO format as follows: population (P) = patients (no age restriction) undergoing orthodontic treatment using fixed, removable, or functional appliances, or patients in the retention phase that are wearing fixed or removable retainers; intervention (I) = mobile applications and social media-based interventions; comparison (C) = control group that did not receive any adjunctive intervention; outcome (O) = behavior changes in orthodontic patients after receipt of the intervention. Two authors independently conducted literature search from inception up to March 2021. DATA ANALYSIS: Social media-based interventions and mobile applications (or bespoke) were used in the form of reminders (WhatsApp reminders) and provision of information including YouTube videos and Instagram posts. Primary outcomes included adherence to wearing appliances or adjuncts, oral hygiene levels, oral health-related behaviors, periodontal outcomes, appointment attendance, knowledge, and related iatrogenic effects. Treatment-related experiences and patient-reported outcomes were assessed as secondary outcomes. RESULTS: 16 studies (14 RCTs and 2 CCTs) were included in the qualitative synthesis, of which only 7 studies were included in the quantitative synthesis (meta-analysis). Results from meta-analyses showed that the intervention was favored in relation to gingival index (GI) (number of studies = 4, standardized mean difference [SMD] = -0.81, 95% confidence interval [CI] = -1.35 to -0.28, P = 0.00, certainty of evidence = very low), plaque index (PI) (number of studies = 7, SMD = -0.91 [95% CI, -1.64 to -0.19], P = 0.01, certainty of evidence = very low), and bleeding index (BI) (number of studies = 4, SMD = -0.22 [95% CI, -0.50 to 0.05], P = 0.11, certainty of evidence = high). Sensitivity analysis was performed (including additional 3 studies for GI and 5 studies for PI), which also favored the intervention in relation to GI (number of studies = 7, SMD = -0.60 [95% CI, -1.01 to -0.18], P = 0.00, certainty of evidence = very low), and PI (number of studies = 12, SMD = -0.67 [95% CI, -1.14 to -0.19], P = 0.01, certainty of evidence = very low). CONCLUSIONS: Limited evidence supports beneficial behavior change among orthodontic patients when using mobile applications or social media-based interventions.

Does motivation via a smartphone application improve oral hygiene in patients undergoing orthodontic treatment?

DESIGN: This is a randomized cohort study. COHORT SELECTION: The inclusion criteria comprised patients aged 14-19 years who started their orthodontic treatment using fixed appliances at the Orthodontic Clinic at Universidade Cruzeiro do Sul, San Paulo, Brazil. Only patients who had smartphones were included in this study. The exclusion criteria comprised patients who had previous orthodontic treatment, presence of any oral pathology, and chronic use of analgesic medication or presence of syndromes. Included patients were randomized to two groups (control and experimental). DATA ANALYSIS: The oral hygiene of the included patients was evaluated clinically at five points in time: before bonding fixed orthodontic appliance (T0), immediately after randomization (T1), at 30 days after the beginning of the intervention (T2), at 60 days after the beginning of the intervention (T3), and at 90 days after the beginning of the intervention (T4). Oral hygiene was assessed using visual plaque index (VPI) and gingival bleeding index (GBI) at six sites of all teeth in every arch excluding third molars. Prior to the intervention, all patients who participated in this study underwent an oral hygiene session aimed to obtain a plaque index equal to zero and were given standardized oral hygiene instructions. Patients included in the control group were not given any structured oral hygiene follow-up in addition to the standard follow-up already established at the orthodontic clinic. Patients in the experimental group were instructed to install an application (A Dentista Cientista) that was designed especially for this study on their smartphones. This application aimed to guide and motivate patients daily in a playful way about performing oral hygiene practices. The application reminded the patients to perform their oral hygiene through an alarm. RESULTS: A total of 11 patients were screened for study eligibility; 3 patients were excluded from the study. Eight patients were included in this study, four patients in each group. Although VPI and GBI values were reduced at T1 and T2 in the experimental group, there were no statistically significant differences for VPI and GBI between the groups at any time evaluated (P > 0.05). The patients who were included in the experimental group reported a good acceptability of the application and they would recommend it to other people. In addition, the patients who were included in the experimental group agreed that oral hygiene is crucial and 75% of them agreed that the application encouraged them to take better care of their oral health. CONCLUSIONS: This study showed that mobile applications might help in improving the oral hygiene of orthodontic adolescent patients.

First evaluation of an app to optimize and organize the processes and assessments in dental clinical courses.

BACKGROUND: Digital teaching and learning tools, such as computer/mobile apps, are becoming an important factor in modern university education. The objective of our study was to introduce, analyze, and assess an organization and dual assessment app for clinical courses in dental medicine. METHODS: This was a survey-based study of dental students from the clinical study phase (4th/5th year; 8th/10th semester) of a department of prosthetic dentistry at a German university hospital about the benefits of a novel web-based and mobile app for organization and dual assessment of dental clinical courses. A total of eight questions were answered in an anonymous online survey. Data were analyzed using the Kolmogorov-Smirnov test, followed by an exploratory data analysis (α < 0.05). RESULTS: The app was given an average grade of 2.4, whereby 56.9% of the respondents rated the app with a grade of 2 (2 = good). In all, 94.6% of the study participants had not experienced any technical problems when using the app. Concerning the assessment, teaching doctor assessment (51.5 [IQR: 44.0]) was rated significantly better (p = 0.002) than self-assessment (39.5 [IQR: 32.8]). CONCLUSIONS: This investigation evaluated a newly introduced app to optimize dental clinical course workflows and assessment. The organizational feature was rated as good, while the daily self- and teaching doctor assessments were evaluated as less important. The results outline how the use of app technologies can provide an infrastructure for managing organization and daily assessments in dental education.

Comparison of Different Clinical Decision Support Tools in Aiding Dental and Medical Professionals in Managing Primary Dentition Traumatic Injuries.

BACKGROUND: Many patients are taken to the emergency room for dental trauma treatment, but studies reveal that medical professionals do not feel confident in diagnosing and treating children with traumatic dental injuries. The purpose of this study was to determine if a clinical decision support tool (CDST) would improve dental trauma knowledge of primary teeth in medical students and pediatric dentists. Another purpose was assessing effectiveness of print and mobile app CDSTs. METHODS: Medical students (n = 100) and pediatric dentists (n = 49) were given a pretest to assess baseline dental trauma knowledge. All subjects were randomly assigned to 1 of 3 groups for the posttest: no CDST, print CDST, and mobile app CDST. Test scores and total time spent on each test were recorded and analyzed. RESULTS: Compared with medical students, pediatric dentists scored significantly higher in both pretest (8.57 ± 0.96 vs 4.20 ± 1.58; P < 0.001) and posttest (8.37 ± 1.09 vs 4.96 ± 1.99; P < 0.001). There was no significant difference in time spent to complete the 2 tests between both groups. Medical students and pediatric dentists who utilized the mobile app CDST had scored highest (P = 0.028) but took the longest time (P < 0.001) on the posttest. CONCLUSIONS: Both print and mobile app CDSTs improved diagnosing and managing traumatic dental injuries in primary dentition significantly compared with those without aid. Medical students with CDSTs showed significant improvement in managing primary dental trauma; therefore, it is recommended for better, more accurate diagnosis and treatment in patients.

Evaluation of the effectiveness of a mobile application in the management of dental anxiety: A randomised controlled trial.

BACKGROUND: The software, which was developed according to the principle of perceived control, can be installed on tablets and smartphones and used by patients to help them control their anxiety. OBJECTIVE: The aim of this study was to evaluate the effectiveness of a specially designed mobile application developed to provide patients with a sense of anxiety control during the various stages of endodontic treatment. The patients' anxiety was assessed by measuring their salivary cortisol levels. METHODS: A total of 46 patients requiring endodontic treatment were recruited. The patients were randomly assigned to two groups. The experimental group used the special communication application, while the control group did not. Salivary samples were collected from all patients preoperatively, postanaesthesia, and postoperatively. The samples were analysed with an enzyme-linked immunosorbent assay to measure the cortisol levels. RESULTS: A significant difference in cortisol levels was observed between the experimental and the control group (Mann-Whitney U-test, p < .05). This difference was significant in the experimental group in each step (p < .01). No difference was found in the control group steps (p > .05). CONCLUSIONS: Perceived control of anxiety using the specially designed software was effective in reducing salivary cortisol levels.

Critical appraisal of the information available on traumatic dental injuries found in applications.

BACKGROUND/AIMS: Traumatic dental injuries (TDI) are a public health problem and the search for information becomes essential to help in their management. The aim of this study was to search existing TDI applications (Apps) to critically describe the characteristics and main information found in them regarding TDI. METHODOLOGY: Searches were performed in the Play Store (Android) and App Store (iOS), using MeSH terms, synonyms and terms related to dental emergencies and TDI, in English, Spanish and Portuguese. Apps with information on the management of post-TDI emergencies or TDI prevention were included. The type of operating system (Android/iOS), cost (free/paid), target audience (dentist/patient), age of classification (free/>17 years old), language, star rating (1★ to 5★), number of downloads and post-download ratings, type of dentition (primary/permanent), reference used for classification according to TDI type and management (International Association for Dental Traumatology/Andreasen/others/not reported), and available content (prevention/emergency management/preservation/illustrations) were evaluated. RESULTS: Among 486 apps, 13 were eligible: 11 for Android and 2 for iOS. Most were free (92.3%), for patients (38.4%) and had a free age classification (90.9%). The main language was English (53.8%), and most of the Apps either had no information on star ratings (46.1%) or received 4★ (23.1%). The number of downloads was not reported (23.1%) or was fewer than 100 (23.1%). Most of the Apps were for permanent teeth (61.5%) and had explanations about dental management for TDI emergencies (92.3%) and multiple TDIs (61.5%). Most Apps addressed the importance of monitoring TDIs (76.9%) and contained illustrative images (76.9%). However, many did not report the TDI classification (46.1%), and 38.5% reported TDI prevention. CONCLUSIONS: Information on dental trauma management according to dental injury, inclusion of images, target audience, type of TDI and their prevention varied in the available Apps. However, most were focused on permanent teeth and addressed several TDI in English language only.
