Content quality and reliability of YouTube videos on oral appliance therapy for obstructive sleep apnea: A systematic analysis.

INTRODUCTION: YouTube's popularity as a health information source raises concerns about credibility due to the absence of peer review. Therefore, this study assessed the content quality and reliability of YouTube videos related to oral appliance therapy for obstructive sleep apnea (OSA). METHODS: Videos were systematically searched on August 20, 2023, using terms determined through Google Trends. Videos were included based on predefined criteria and independently assessed by two researchers. Video demographics were extracted. Video quality was evaluated using audio-visual (AV) quality, video information and quality index (VIQI), global quality score (GQS), and reliability using a modified DISCERN tool (mDISCERN). High and low-content videos were defined based on the customized 10-point scoring system. Inter- and intra-examiner reliability of scoring system were calculated. RESULTS: Most videos were educational (46.3%), presented by dental sleep medicine specialists (42.6%), and aimed at laypersons (63%), with the majority originating from the United States (79.6%). The final 54 videos were categorized as high-content (n = 29, 54%) and low-content (n = 25, 46%). High-content videos had more views, comments, and longer video durations (7.07 ± 6.04 min). Significant differences (p < .05) were observed among high and low-content videos in total VIQI, mDISCERN, GQS, and TCS. Moderate correlations were found between GQS and TCS (r = 0.721), mDISCERN and VIQI (r = 0.649), GQS and VIQI (r = 0.601), and AV quality and VIQI (r = 0.531). CONCLUSION: The study highlights variable content quality and reliability of YouTube videos on oral appliance therapy for OSA, emphasizing the need for guidelines to enhance their educational value and deliver reliable, evidence-based information to patients.

Effect of adjuvant autologous platelet concentrates on secondary repair of alveolar clefts: A systematic review and meta-analysis.

OBJECTIVE: To review the existing evidence on the adjuvant use of autologous platelet concentrates (APCs) with iliac crest bone graft (ICBG) in the reconstruction of the secondary alveolar cleft. METHODS: Electronic databases were searched systematically until November 2022. Clinical trials comparing the three-dimensional radiological outcomes of patients who underwent secondary alveolar bone grafting (SABG) with ICBG and APCs to those with ICBG alone and the radiological outcomes assessed 6 months after surgery were included. Two authors performed the study selection and the assessment of the risk of bias. Meta-analysis was performed using the random-effects model to determine the risk ratio (RR) for developing wound dehiscence and the mean difference (MD) with a 95% confidence interval (CI) for the percentage of newly formed bone. RESULTS: Nine studies (seven RCT and two CCT) were included with a low to high risk of bias. At the 6-month follow-up, the study group revealed insignificant results regarding the percentage of newly formed bone (MD = 6.49; 95% CI: -0.97, 13.94; p = .09; χ2  = 0.01; I2  = 71%). In addition, the overall risk of developing wound dehiscence was lower in the study group (RR = 0.34; 95% CI: 0.15, 0.78; p = .01; χ2  = 0.67; I2  = 0%). CONCLUSION: Currently, there is insufficient evidence to support the adjuvant use of APCs with ICBG on enhanced bone regeneration following secondary alveolar bone grafting. However, combining ICBG and APCs might be beneficial in reducing the risk of developing wound dehiscence.

A Rare Incidence of Nonsyndromic Mandibular Incisor Agenesis in a Three-generation Family: Case Report and Literature Review.

Hypodontia is an inherited condition involving the absence of one to six teeth. The permanent dentition is the most frequently affected; however, it may also affect the primary dentition. A congenitally missing tooth (CMT) is the most common dental abnormality, with the missing mandibular second premolar, maxillary lateral incisor, maxillary second premolar, and mandibular central incisor accounting for 90% of CMT in hypodontia studies. The etiology of CMT has been attributed to environmental and genetic contributing factors, with the latter having a strong influence. It may occur in isolation or in association with syndromes. Congenitally missing mandibular incisor is more common in the Asian population and females. Depending on the number and location of missing teeth, hypodontia may be a considerable issue for the clinician since it may impact occlusal balance, mastication, speech, and esthetics and often requires a multidisciplinary approach. Missing mandibular incisors are of particular interest to orthodontists because of the possibility of mandibular retrognathism, the potential for the development of malocclusion, and difficulty in achieving a balanced occlusion. This case report describes the skeletal and dental features of a nonsyndromic familial occurrence of missing mandibular incisors in three generations. A comprehensive literature search was also performed to review the familial cases with missing mandibular incisors. How to cite this article: Selvaraj M, Sennimalai K, Samrit VD, et al.

Effect of oral environment on contemporary orthodontic materials and its clinical implications.

Contemporary orthodontics entails using advanced materials and devices, simplifying the process of tooth movement. It is well documented that orthodontic materials are subjected to various fluctuations and stresses in the oral environment, such as salivary pH, dietary habits, temperature changes, and masticatory loads. These changes reduce bonding materials' longevity, plasticize resin polymers, and reduce elastic properties. In addition, the corrosion of orthodontic appliances in the oral environment has concerned clinicians for some time. This is focused on two principal issues: whether corrosion products are absorbed into the body and cause either localized or systemic effects, and the results of corrosion on the physical properties and the clinical performance of orthodontic appliances. Recently, another major concern is the potential release of bisphenol-A from materials containing polymers such as thermoplastic aligners and resins, which is known to induce xenoestrogenicity and cytotoxicity when the tissue level exceeds the daily recommended intake. However, most of these findings are based on in vitro studies that suffer from serious drawbacks such as failure to replicate the exact oral environment and process during orthodontic treatment. Therefore, developing clinically relevant methods should be the goal of future research related to the aging of orthodontic materials. The purpose of this review is to outline the impact of the oral environment on contemporary orthodontic materials.

MRI-based cephalometrics: a scoping review of current insights and future perspectives.

OBJECTIVE: This review aims to explore the current status of magnetic resonance imaging (MRI) as a cephalometric tool, summarize the equipment design and methods, and propose recommendations for future research. METHODS: A systematic search was conducted in electronic databases, including PubMed, Ovid MEDLINE, Scopus, Embase, Web of Science, EBSCOhost, LILACS, and Cochrane Library, using broad search terms. The articles published in any language till June 2022 were considered. Cephalometric studies conducted using the MRI dataset on human participants, phantom or cadaver were included. Two independent reviewers assessed the final eligible articles using the quality assessment score (QAS). RESULTS: Nine studies were included in the final assessment. Studies used various methods, including 1.5 T or 3 T MRI systems and 3D or 2D MRI datasets. Among the imaging sequences, T1-weighted, T2-weighted and black bone MR images were used for cephalometric analysis. In addition, the reference standards varied among studies, such as traditional 2D cephalogram, cone-beam CT and phantom measurements. The mean QAS of all the included studies was 79% (± 14.4%). The main limitation of most studies was the small sample size and the heterogeneity of the methods, statistical tools used, and metric outcomes assessed. CONCLUSIONS: Despite the heterogeneity and lack of metrological evidence on the effectiveness of MRI-based cephalometric analysis, the preliminary results demonstrated by in vivo and in vitro studies are encouraging. However, future studies exploring MRI sequences specific to cephalometric diagnosis are required for wider adoption of this technique in routine orthodontic practice.

Binder's syndrome: A narrative review.

AIM: The classical features of Binder's syndrome (BS) have been widely reported, yet there is a lack of information on diagnostic and treatment challenges. Therefore, we aimed to review the literature on various aspects, including the role of a multidisciplinary approach in the management of BS. METHODS: A thorough literature search was performed on PubMed, Scopus, Embase, Ovid, Web of Science, EBSCOhost, and Google Scholar using the keywords"Maxillonasal dysplasia", "Maxillonasal dysostosis", "nasomaxillary hypoplasia", "Binder type", "Binder syndrome", "Binder phenotype", and "OMIM 155050". In addition, the articles published in the English language from the inception of the database until June 2021 were considered. RESULTS: The search of different databases yielded 958 publications, out of which 145 relevant articles were reviewed. The studies were categorised by year of publication, study design, and theme. Most of the studies were case reports (42%) followed by case series (19%). The most reported topic was based on different surgical techniques (42%). Finally, the results were synthesised into a narrative review. CONCLUSIONS: The need for a multidisciplinary approach involving clinicians from different specialities is highlighted. Future research is warranted to develop concrete clinical guidelines for the management of this syndrome.

A Rare Case of Cleft Palate Associated With Tongue Hamartoma: A Case Report and Systematic Review.

INTRODUCTION: Palate development involves a genetic regulation through a complex molecular mechanism that may be disrupted by environmental factors, resulting in impaired fusion and cleft palate formation. An encounter with a case of cleft palate due to dorsal tongue hamartoma prompted us to perform this systematic review. OBJECTIVE: To review the clinical profile and management approach for a case with cleft palate and tongue hamartoma. DESIGN: A systematic literature search was conducted using keywords related to cleft palate and tongue hamartoma in PubMed, Scopus, MEDLINE, and Scielo databases through December 2021, with no time or language restrictions. PATIENTS, PARTICIPANTS: Studies reporting patients with cleft palate and tongue hamartoma were included. MAIN OUTCOME MEASURE(S): Information related to clinical profile, diagnostic tests, histopathology, management, and outcomes were extracted.Fourteen relevant publications were identified with 16 cases reported so far. Among them, thirteen patients were females (81.25%), and 3 were males (18.75%). The age of presentation varied from birth to 19 years. Oral-facial-digital syndrome (type II) was the most commonly associated syndrome.Congenital tongue hamartoma with cleft palate is a rare presentation, which can present as an isolated entity or part of a syndrome. Genetic evaluation is warranted, particularly for multiple hamartomatous lesions. The preferred treatment is immediate excision of hamartoma while following a standard timeline for palatoplasty.

Applications of artificial intelligence and machine learning in orthognathic surgery: A scoping review.

Over the recent years, Artificial Intelligence (AI) has been progressing rapidly with its ability to mimic human cognitive functions. The potential applications of AI technology in diagnosis, treatment planning, and prognosis prediction have been demonstrated in various studies. The present scoping review aimed to provide an overview of AI and Machine Learning (ML) algorithms and their applications in orthognathic surgery. A comprehensive search was conducted in databases including PubMed, Embase, Scopus, Web of Science and OVID Medline until November 2021. This scoping review was conducted following the PRISMA-ScR guidelines. After applying the inclusion and exclusion criteria, a total of 19 studies were included for final review. AI has profoundly impacted the diagnosis and prediction of orthognathic surgeries with a clinically acceptable accuracy range. Furthermore, AI reduces the work burden of the clinician by eliminating the tedious registration procedures, thereby helping in efficient and automated planning. However, focussing on the research gaps, there is a need to foster the AI models/algorithms to contemporize their efficiency in clinical decision making, diagnosis and surgical planning in future studies.

Adjunctive orthodontic therapy for prosthetic rehabilitation in a growing child with Axenfeld-Rieger syndrome: A case report.

AIM: The congenital oligodontia impeding the development of the alveolar process resulting in disproportionate jaw growth has been previously reported. This case report describes the interdisciplinary management of an 11-year-old girl with Axenfeld-Rieger syndrome exhibiting oligodontia and maxillary hypoplasia. METHODS AND RESULTS: An adjunctive orthodontic therapy was performed by taking advantage of bone-anchored maxillary protraction (BAMP) therapy using miniplates and 24-hour traction by intermaxillary Class III elastics. After 6 months of active treatment, the maxilla advanced by approximately 5 mm and upper lip relation improved by 3 mm without any significant changes in vertical relations. All the changes were maintained at 15th-month follow-up. A temporary removable prosthesis was given for immediate esthetics, and the definitive management is discussed. CONCLUSION: The BAMP therapy can be a befitting alternative in cases exhibiting complex presentation involving skeletal and dentoalveolar components. An appreciable profile improvement without any dentoalveolar side effects can be achieved with BAMP therapy.
