Utilising massive open online courses to enhance global learning dissemination in cleft lip and palate: a case report of penta helix collaboration.

BACKGROUND: Educating and raising awareness in cleft lip and palate future generations is one vital effort to ensure the improvement of cleft care and research in the future. This study reported the overview in organising and evaluating the Massive Open Online Course (MOOC) in Cleft Lip and Palate as the alternative way for students' capacity building outside their study program whilst also earning credits towards their studies. METHODS: Smile Train cleft charity generously donated recorded lectures from cleft experts around the world in which each of the experts agreed to provide one-hour live discussion sessions. The learning activities ranging from lectures, pre- and post-course evaluation, forum, live discussion sessions, virtual visits to Indonesian Cleft Centre, self-reflection assignments and final project. A survey was released to the participants to collect their feedback. RESULTS: The course mainly attracted dental students, and several allied health professional students. In total, 414 out of 717 participants registered for this MOOC managed to finish the course and received a certificate of completion which was run between August-October 2021. In general, participants positively received the course. CONCLUSIONS: The MOOC model and its objective of disseminating widespread information across geographical boundaries to enhance learning about cleft lip and palate treatment was achieved. This report serves as an example for other educational institutions and stakeholders who plan to use online educational engagement platforms to provide high-quality education and capacity building to participants in lower-middle income countries.

Scoping review of outcome measures in cleft care used in research and reports.

Treatment outcome measures are critical in the decision making of best practices in the OFC field. OFC consortium working groups provided standardization of outcome measures based on previous treatment outcome studies. However, the implementation of such standardization in OFC centres worldwide is unknown. This study presented mapped outcome measures in cleft care using a structured review method complemented by quantitative overview of the relevant published research to provide initial guidelines for the implementation of treatment outcome standardization. A scoping review of the literature of treatment outcomes in cleft care following Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines was performed. The selected indexed paper in outcome measures mapped following the international consortium in standard set of outcome measures in cleft care. Three hundred and sixty-five articles were filtered. The most discussed domains of cleft care were dental and oral health, appearance and speech/communication. Overall, the majority of publications were produced in high-income countries. The current review indicates that there are inequalities of treatment outcome studies among the domain of cleft care. In addition, there are also inequalities of published articles from HIC versus LMIC in treatment outcomes. This information can be used to develop targeted interventions aimed at encouraging cleft centres worldwide to adapt standardized outcome measures.

Classification Systems of Cleft Lip, Alveolus and Palate: Results of an International Survey.

OBJECTIVE: This study aimed to identify commonly used classification systems by cleft providers around the world, including the perceived indications and limitations of each system. DESIGN: A cross-sectional survey. PARTICIPANTS: A total of 197 registrants from three international cleft/craniofacial meetings. INTERVENTIONS: Participants were sent a web-based questionnaire concerning cleft classification systems. MAIN OUTCOME MEASURES: Frequency of commonly used classification systems, their perceived indications and limitations. RESULTS: A total of 197 respondents from 166 different centers completed the questionnaire. Healthcare professionals from all disciplines responded, with the most frequent respondents being plastic surgeons (38.1%), maxillofacial surgeons (28.4%) and orthodontists (23.9%). Eighteen different classification systems were in use. The most frequently used systems were the International Statistical Classification of Diseases and Related Health Problems (ICD-10) (35.5%), LAHSHAL (34.0%), and Veau (32.5%) classification systems. Most respondents (32.5%) indicated that anatomical and morphological characteristics are essential components of a classification system. However, respondents indicated that their current classification systems lacked sufficient description of cleft extension and severity. CONCLUSIONS: Great variety in the use of classification systems exists among craniofacial specialists internationally. The results recommend the usage of the LAHSHAL classification of OFCs, due to its comprehensiveness, relatively high implementation rate globally, convenience of usage and complementarity with the ICD-10 system. Moreover, it can overcome deficiencies inextricably linked to ICD-10, such as incapacity to describe laterality and clefts of the alveolus. More international exposure to the merits of using the LAHSHAL classification system would be highly recommended.

Caries in children with and without orofacial clefting: A systematic review and meta-analysis.

This systematic review compared children's primary dentition caries experience for those with cleft lip and/or palate (CL/P) and without. Four databases were searched without date restriction for; cross-sectional studies comparing caries experience for children with CL/P to those without. Screening, data extraction and risk assessment were carried out independently (in duplicate). Meta-analyses used a random-effects model. Twenty studies (21 reports) fitting the inclusion criteria comprised 4647 children in primary dentition from 12 countries. For dmft (n = 3016 children; 15 groups), CL/P mean = 3.2; standard deviation = 2.22 and no CL/P mean dmft = 2.5; sd 1.53. For dmfs (n = 1095 children; 6 groups), CL/P mean = 4; sd = 3.5 and no CL/P mean = 3; sd = 2.8. For % caries experience (n = 1094 children; 7 groups), CL/P mean = 65%; sd = 20.8 and no CL/P mean = 52%; sd = 28.1. Meta-analysis showed higher caries experience in children with CL/P, standardised mean difference = 0.46; 95% CI = 0.15, 0.77. Studies' risk of bias was high (n = 7), medium (n-10) and low (n = 3). Children with CL/P had higher caries experience compared to those without CLP.

Facial Anthropometry Measurements Using Three-Dimensional Stereophotogrammetry Analysis Among Nigerians.

ABSTRACT: This study aimed to determine the normative facial anthropometry measurement among Nigerians using three-dimensional stereophotogrammetry analysis.This study was carried out in Lagos, Nigeria over a period of 3 years. The sample population was Nigerians of diverse ethnic groups, age 16 and above with no history of congenital or acquired craniofacial deformities.A total of 452 subjects participated in the study with 56.2% males and 43.8% females. Most of the participants were between the ages of 25 to 49 (54.4%), 40.7% were less than 25 years of age and only 4.4% were more than 50 years old. The mean body mass index (BMI) for males was 22.7 and 23.4 for females. Mean values of upper facial height, midfacial height, lower facial height, intercanthal distance, interpupillary distance, upper facial width, and lower facial width are 69.13 ±â€Š5.91, 49.89 ±â€Š3.56, 67.85 ±â€Š6.12, 35.19 ±â€Š3.20, 67.04 ±â€Š3.67, 139.43 ±â€Š7.11, and 124.29 ±â€Š9.72 mm, respectively. The upper facial height, commissure width, upper lip length, and lower jaw width were significantly affected by age, while the BMI of an individual was a determinant of the interpupillary distance, facial width, and lower jaw width.This study demonstrated that there was a statistically significant difference in the facial dimensions of males when compared to females across all ages among the study population. The authors also observed that age and BMI are significant predictors of variations in some of the measurements.

Systematic Review of Clinical Practice Guidelines for Oral Health in Children With Cleft Lip and Palate.

OBJECTIVE: Clinical practice guidelines (CPGs) exist to present recommendations and policies aimed at optimizing the oral health of children and adolescents born with cleft lip and/or palate. The aim of this review is to identify and assess the scope, quality, adequacy, and consistency of CPGs related to oral health in children and adolescents with clefts, along with reporting any differences and shortcomings. METHODS: A systematic review of the literature of CPGs following Preferred Reporting Items for Systematic Reviews guidelines was conducted. Assessment of selected CPGs was performed using the Appraisal of Guidelines for Research & Evaluation II methodological quality instrument. RESULTS: Only 7 CPGs fulfilled the criteria. Of these, 4 were from the American Cleft Palate-Craniofacial Association, and 1 each from the American Academy of Pediatrics, the Academy of Breastfeeding Medicine, and the American Academy of Pediatric Dentistry. The lowest overall mean scores were in the domain "Rigor of Development" (mean 29.58%, SD 17.11), revealing lower quality in methodology of the guideline. The domain "Clarity of Presentation" (mean 73.80%, SD 7.87) revealed the best score. CONCLUSIONS: Our review results reveal a lack of integrated high-quality CPGs that can be used as universal guidelines by health workers in a range of disciplines for improving oral health in children and adolescents with cleft problems.

Development of intra-oral automated landmark recognition (ALR) for dental and occlusal outcome measurements.

BACKGROUND: Previous studies embracing digital technology and automated methods of scoring dental arch relationships have shown that such technology is valid and accurate. To date, however there is no published literature on artificial intelligence and machine learning to completely automate the process of dental landmark recognition. OBJECTIVES: This study aimed to develop and evaluate a fully automated system and software tool for the identification of landmarks on human teeth using geometric computing, image segmenting, and machine learning technology. METHODS: Two hundred and thirty-nine digital models were used in the automated landmark recognition (ALR) validation phase, 161 of which were digital models from cleft palate subjects aged 5 years. These were manually annotated to facilitate qualitative validation. Additionally, landmarks were placed on 20 adult digital models manually by 3 independent observers. The same models were subjected to scoring using the ALR software and the differences (in mm) were calculated. All the teeth from the 239 models were evaluated for correct recognition by the ALR with a breakdown to find which stages of the process caused the errors. RESULTS: The results revealed that 1526 out of 1915 teeth (79.7%) were correctly identified, and the accuracy validation gave 95% confidence intervals for the geometric mean error of [0.285, 0.317] for the humans and [0.269, 0.325] for ALR-a negligible difference. CONCLUSIONS/IMPLICATIONS: It is anticipated that ALR software tool will have applications throughout clinical dentistry and anthropology, and in research will constitute an accurate and objective tool for handling large datasets without the need for time intensive employment of experts to place landmarks manually.

Nose profile morphology and accuracy study of nose profile estimation method in Scottish subadult and Indonesian adult populations.

This study investigated nose profile morphology and its relationship to the skull in Scottish subadult and Indonesian adult populations, with the aim of improving the accuracy of forensic craniofacial reconstruction. Samples of 86 lateral head cephalograms from Dundee Dental School (mean age, 11.8 years) and 335 lateral head cephalograms from the Universitas Padjadjaran Dental Hospital, Bandung, Indonesia (mean age 24.2 years), were measured. The method of nose profile estimation based on skull morphology previously proposed by Rynn and colleagues in 2010 (FSMP 6:20-34) was tested in this study. Following this method, three nasal aperture-related craniometrics and six nose profile dimensions were measured from the cephalograms. To assess the accuracy of the method, six nose profile dimensions were estimated from the three craniometric parameters using the published method and then compared to the actual nose profile dimensions.In the Scottish subadult population, no sexual dimorphism was evident in the measured dimensions. In contrast, sexual dimorphism of the Indonesian adult population was evident in all craniometric and nose profile dimensions; notably, males exhibited statistically significant larger values than females. The published method by Rynn and colleagues (FSMP 6:20-34, 2010) performed better in the Scottish subadult population (mean difference of maximum, 2.35 mm) compared to the Indonesian adult population (mean difference of maximum, 5.42 mm in males and 4.89 mm in females).In addition, regression formulae were derived to estimate nose profile dimensions based on the craniometric measurements for the Indonesian adult population. The published method is not sufficiently accurate for use on the Indonesian population, so the derived method should be used. The accuracy of the published method by Rynn and colleagues (FSMP 6:20-34, 2010) was sufficiently reliable to be applied in Scottish subadult population.

Digital Three-Dimensional Automation of the Modified Huddart and Bodenham Scoring System for Patients With Cleft Lip and Palate.

OBJECTIVE: The modified Huddart and Bodenham scoring system assesses maxillary arch constriction and surgical outcomes in cleft lip and palate. This project automates modified Huddart and Bodenham scoring using three-dimensional digital models. DESIGN: Development of a novel software tool. SETTING: The design, construction, development, and testing of the system was carried out at Dundee Dental Hospital. PATIENTS, PARTICIPANTS: Subjects with cleft lip and palate. INTERVENTIONS: A plug-in has been developed using an open three-dimensional development platform: Rhinoceros, version 5 ( http://www.rhino3d.co.uk ). Users select cusps on mandibular and maxillary teeth on three-dimensional digital models. A three-dimensional cubic spline generates a mandibular curve, and a best-fit horizontal mandibular reference plane is produced using a least-squares method. Horizontal distances projected from the shortest three-dimensional distances were subsequently calculated between the maxillary cusps and the mandibular curve to calculate the modified Huddart and Bodenham score. MAIN OUTCOME MEASURES: Automatic scoring of digital models using the modified Huddart and Bodenham system produces similar results to manual scoring. RESULTS: By standardizing outcome assessment in cleft care, multicenter comparisons for audit and research can be simplified, allowing centers throughout the world to upload three-dimensional digital models or intraoral scans of the dental arches for remote scoring. Thereafter, these data can feed back into the global database on orofacial clefting as part of the World Health Organization's international collaborative "Global Burden of Disease" research project for craniofacial anomalies. CONCLUSIONS: The automated system facilitates quicker and more reliable outcome assessments by minimizing human errors.

The validity and reliability of an automated method of scoring dental arch relationships in unilateral cleft lip and palate using the modified Huddart-Bodenham scoring system.

OBJECTIVE: To evaluate an automated software tool for the assessment of dental arch relationships using the modified Huddart and Bodenham (MHB) index. DESIGN: Cohort of 43 models of subjects aged 9-21 with UCLP and the ten GOSLON reference models sets. METHOD: The 53 sets of plaster models were scored using the MHB index and scanned with a benchtop scanner. The digital models were MHB scored visually using a commercial software program and landmarked for automatic scoring using a software plug-in. Scoring/landmarking was undertaken by three observers and repeated after 1 month. Intra- and inter-observer reproducibility were tested using Cronbach's alpha and intraclass correlation coefficients (ICC) (threshold > 0.9). Bland-Altman plots demonstrated inter-observer agreement for each model format. Random and systematic error with digital landmark identification error were determined using the x, y, and z co-ordinates for 28 models digitized twice 1 month apart using Cronbach's alpha and a t-test, respectively. RESULTS: Intra-operator landmark identification was excellent (Cronbach's alpha = 0.933) with no differences between sessions (P > 0.05). Intra-observer reproducibility was excellent for all examiners (Cronbach's alpha and ICC 0.986-0.988). Inter-observer reproducibility was highest for the software plug-in (0.991), followed by plaster (0.989) and OrthoAnalyzer (0.979) and Bland-Altman plots confirmed no systematic bias and greater consistency of scores with the automated software. CONCLUSION: The automated MHB software tool is valid, reproducible, and the most objective method of assessing maxillary arch constriction for patients with UCLP. CONFLICT OF INTEREST STATEMENT: The authors declare no conflict of interest or financial relationship with any organization or software used within the study.

Validating the Clinical Use of the Modified Huddart and Bodenham Scoring System for Outcome in Cleft Lip and/or Palate.

OBJECTIVE: The aim of this study was to validate the clinical use of the modified Huddart and Bodenham scoring system for the measurement of maxillary arch constriction in children born with cleft lip and/or palate. DESIGN: The study design consisted of a reliability assessment between clinical and study model scoring. SETTING: The study was carried out in cleft clinics at three hospital-based orthodontic units. PARTICIPANTS: A total of 53 subjects were recruited when attending routine clinic appointments and gave informed consent to participate. INTERVENTION: The modified Huddart and Bodenham scoring system was applied to study models for 53 subjects by all examiners; whereas, one examiner scored 53 subjects clinically, the other two examiners scored 25 and 28 subjects, respectively, on two occasions at least 1 month apart. MAIN OUTCOME MEASURE: Reliability of modified Huddart and Bodenham scoring clinically and on study models was compared. RESULTS: When scoring clinically with the modified Huddart and Bodenham index on two occasions, the intraexaminer and interexaminer intraclass correlation coefficients (ICC) indicated a high level of repeatability and reliability (ICC range, 0.941 to 0.989). The Bland-Altman plots did not show any areas of systematic bias. The ICC between clinical and model scores for each examiner ranged between 0.923 and 0.959. The Bland-Altman plots did not show any areas of systematic bias. The ICC between clinical and model scores for each examiner ranged between 0.923 and 0.959. Canines had lower reliability than molars and incisors. CONCLUSIONS: There was excellent intraexaminer and interexaminer agreement both on study models and in the intraoral scoring using the modified Huddart and Bodenham index. In addition, there was a high degree of correlation between study model and clinical scores using this index.

Orthodontic scanners: what's available?

The popularity and availability of virtual technology in orthodontics for the replacement of hard-copy records with electronic records is growing rapidly, with a move towards a 'digital' patient for diagnosis, treatment planning, monitoring of treatment progress and outcome. As part of this ongoing development, three-dimensional digital models of the dental arches have the potential to replace traditional plaster models and their associated limitations for treatment planning, appliance construction and simulated treatment outcomes. This article provides the reader with a summary of the currently available benchtop model scanners and intraoral scanners. It is likely that this technology will become increasingly common-place within the orthodontic profession over the next decade.

FAF1, a gene that is disrupted in cleft palate and has conserved function in zebrafish.

Cranial neural crest (CNC) is a multipotent migratory cell population that gives rise to most of the craniofacial bones. An intricate network mediates CNC formation, epithelial-mesenchymal transition, migration along distinct paths, and differentiation. Errors in these processes lead to craniofacial abnormalities, including cleft lip and palate. Clefts are the most common congenital craniofacial defects. Patients have complications with feeding, speech, hearing, and dental and psychological development. Affected by both genetic predisposition and environmental factors, the complex etiology of clefts remains largely unknown. Here we show that Fas-associated factor-1 (FAF1) is disrupted and that its expression is decreased in a Pierre Robin family with an inherited translocation. Furthermore, the locus is strongly associated with cleft palate and shows an increased relative risk. Expression studies show that faf1 is highly expressed in zebrafish cartilages during embryogenesis. Knockdown of zebrafish faf1 leads to pharyngeal cartilage defects and jaw abnormality as a result of a failure of CNC to differentiate into and express cartilage-specific markers, such as sox9a and col2a1. Administration of faf1 mRNA rescues this phenotype. Our findings therefore identify FAF1 as a regulator of CNC differentiation and show that it predisposes humans to cleft palate and is necessary for lower jaw development in zebrafish.

Could retaining the dental recall interval save NHS dentistry?

The World Health Assembly in May 2021 was a watershed moment in oral health, with the landmark resolution that designated oral diseases as non-communicable diseases (NCDs). This was strongly supported by a host of other NCDs in recognition of the common risk factor principle and acknowledgement of the fact that oral diseases do not occur in isolation from other NCDs, but are commonly associated with cardiovascular disease, diabetes/obesity, respiratory diseases, metabolic syndrome, a range of other inflammatory disorders and cancers. Regular monitoring and early detection would potentially intercept these NCDs and this could form a central plank of a revamped holistic 'health'- as opposed to 'disease'-oriented health care system.Consultation with patients and dentists reveals strong support for maintaining regular recall intervals, which maintains trust and optimises motivation and compliance. In-person visits could be minimised by using technology, such as remote consultations and longitudinal monitoring systems, making it adaptable to different health care settings and equitable, affordable, cost-effective and sustainable.A new paradigm with dentists as oral health professionals, and the mainstreaming of oral health and population-level prevention, means the future of health care can be guided by integration and workforce modification producing a surveillance-based, early interceptive, preventive model of care.

Adult attitudes to sustainable dentistry in Trinidad and Tobago and their willingness to accept alternatives.

INTRODUCTION: Attitudes towards and willingness to accept alternatives for sustainable dentistry in Trinidad and Tobago have never been assessed. Market research aids in the understanding of the behaviours of people. Since change can be enacted by public pressure, it is worth engaging the public through research to understand their attitudes and which changes they are willing to accept. METHOD: A self-administered questionnaire was distributed to private and public dental clinics. The questionnaire assessed attitude towards and willingness to accept alternatives which decrease the effect of dental treatment on the environment. RESULTS: The study consisted of 1267 participants. Participants were mostly female, older, employed and mainly of African descent. Participants reported a very positive attitude towards sustainable dentistry (Mean = 3.89, SD = 0.8). and were moderately willing to accept alternatives such as a longer appointment time (Mean 3.47, SD = 0.73) and pay more for their dental treatments (Mean=3.00, SD = 0.87). There was a strong positive correlation with attitudes to sustainable dentistry and participants willingness to accept alternatives such as a longer appointment time (r = 0.658, p < 0.05). CONCLUSION: The adult population had an overall positive attitude towards sustainable dentistry and was willing to accept alternatives so that their dental treatment would have less impact on the environment.

Validation of conventional 2D lateral cephalometry using 3D cone beam CT.

OBJECTIVE: To determine if two-dimensional (2D) measurements from conventional cephalometric lateral skull radiographs are comparable to those derived from three-dimensional (3D) cone beam computed tomography (CBCT) images. DESIGN: In vitro laboratory study. SETTING: University Dental Hospital. METHODS: A sample size calculation determined that 14 dried skulls were required to detect a 2° difference in angular measurements. The skulls were scanned at 0·3 mm(3) voxel size. Maximum intensity projection (MIP) views were uploaded into OPAL cephalometric software (British Orthodontic Society, London, UK) for 2D analysis. CBCT data was uploaded into Mimics (Materialise, Leuven, Belgium) with 3D reconstructed and sagittal slice views being used. An Eastman analysis was carried out for the 2D and 3D images with the data compared using two-sample t-tests at P<0·05. Measurements greater than 2° between the 2D and 3D data were considered clinically significantly different. Intra-observer reproducibility was assessed by calculating random and systematic error using the Dahlberg formula and a two-sample t-test (P<0·05). RESULTS: The random error was below 0·5° and the systematic error was acceptable (P<0·05). There were no statistically significant differences between the measurements from the 2D and 3D images for any variable (P<0·05). However, the mean SNB value and the mean value for the angle between the lower incisor and mandibular plane differed by greater than 2° between the 2D and 3D data. The latter was thought to be due to limitations of the definition of Gonion for 3D images and the precision of locating the lower incisor apex in 2D. CONCLUSION: Measurements used in the Eastman cephalometric analysis derived from 2D cephalometric lateral skull images are comparable to those derived from 3D CBCT images.

Global perspectives in orofacial cleft management and research.

Orofacial clefts (OFCs) refer to clefts of the lip and palate, a heterogeneous group of relatively common congenital conditions that can cause mortality and significant disability if untreated, and residual morbidity even when treated with multidisciplinary care. Contemporary challenges in the field include: lack of awareness of OFCs in remote, rural and impoverished populations; uncertainties due to lack of surveillance and data gathering infrastructure; inequitable access to care in some parts of the world; and lack of political will combined with lack of capacity to prioritise research.OFCs present clinically as either syndromic or non-syndromic, with the latter either being isolated or in conjunction with other malformations; however, many registries still do not differentiate between these fundamentally different entities and lump a spectrum of cleft types and sub-phenotypes together. This has implications for treatment, research and ultimately, quality improvement.This paper deals with the challenges in contemporary management in terms of care and the prospects and possibilities for primary prevention of non-syndromic clefts. In terms of management and optimal care, there are also challenges in the provision of multi-disciplinary treatment and management of the consequences of being born with OFCs, such as dental caries, malocclusion and psychosocial adjustment.

Health Coaching-Based Interventions for Oral Health Promotion: A Scoping Review.

BACKGROUND: Health coaching-based interventions can support behaviour change to improve oral health. This scoping review aims to identify key characteristics of health coaching-based interventions for oral health promotion. METHODS: The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist and the Joanna Briggs Institute manual for evidence synthesis were used in this review. A search strategy using medical subject heading terms and keywords was developed and applied to search the following databases: CINAHL, Ovid, PubMed, Cochrane Library and Scopus. Thematic analysis was used to synthesise the data. RESULTS: Twenty-three studies met the inclusion criteria and were included in this review. These studies were predominantly based on health coaching and motivational interviewing interventions applied to oral health promotion. The following are the characteristics of health coaching-based interventions extracted from themes of the included studies: (a) Health professionals should be trained on the usage of motivational interviewing/health coaching interventions; (b) oral health professionals should acquire motivational techniques in their practice to engage patients and avoid criticisms during the behaviour change process; (c) routine brief motivational interviewing/health coaching intervention sessions should be introduced in dental clinics; (d) traditional oral health education methods should be supplemented with individually tailored communication; and (e) for cost-effectiveness purposes, motivational interviewing/health coaching strategies should be considered. CONCLUSIONS: This scoping review reveals that health coaching-based techniques of health coaching and motivational interviewing can significantly impact oral health outcomes and behaviour change and can improve oral health professional-patient communication. This calls for the use of health coaching-based techniques by dental teams in community and clinical settings. This review highlights gaps in the literature, suggesting the need for more research on health coaching-based intervention strategies for oral health promotion.

Helping general dental practitioners use the Index of Orthodontic Treatment Need: an assessment of available educational apps.

Introduction The Index of Orthodontic Treatment Need (IOTN) defines who receives treatment on the NHS. The British Orthodontic Society developed the 'Easy IOTN' app to help the dental team use IOTN more effectively.Aim This study aims to investigate the quality of the 'Easy IOTN' app and any alternative mobile apps developed to aid a dentist's ability to use IOTN.Materials and methods The App Store and Google Play were searched to identify available apps which provide an educational resource for IOTN. Any app identified was assessed using the Mobile App Rating Scale (MARS) and the Royal College of Physicians' health informatics unit checklist. The 'Easy IOTN' app continuous professional development (CPD) section was assessed for accuracy using a focus group.Results Only the 'Easy IOTN' app was identified. It has a mean MARS score of 3.6. Significant inaccuracies were found within the CPD component of the 'Easy IOTN' app.Discussion A mean MARS score of 3.6 is deemed average and is comparable to the quality of other orthodontic apps which exist. Errors contained within the CPD component could confuse users and have a negative impact on IOTN skill development.Conclusions The educational component of the 'Easy IOTN' app is of an acceptable standard, but the CPD section is flawed.
