RESUMO

Aim: To evaluate orthodontists' knowledge and clinical practices regarding the treatment of patients with HIV/AIDS. Methods: Cross-sectional study performed with 655 Brazilian orthodontists based on a previously calculated sample size. Self-administered questionnaires were sent to orthodontists to collect information on knowledge and clinical conduct regarding the care of patients with HIV/AIDS. The study evaluated the awareness of possible risk factors for contamination, oral manifestations of HIV, need for more information on the care of HIV-positive patients, whether orthodontic treatment is indicated in HIV-positive patients, and whether they had knowingly performed orthodontic treatment in HIV-positive patients. Simple regression models were adjusted, and crude Odds Ratios estimated the associations with 95% confidence intervals. The variables with P < 0.20 in the crude analysis were tested in multiple logistic regression models, and those with P ≤ 0.05 were maintained in the final model. Magnitudes were estimated by adjusted Odds Ratios values, with 95% confidence intervals. Results: Orthodontists who were aware of the oral manifestations of HIV/AIDS, those having work experience of more than 20 years, and those who believed that orthodontic treatment could be indicated for these patients were 3.30 (1.79-6.10), 2.74 (1.36-5.52) and 1.92 (1.13-3.24) times more likely to perform orthodontic treatment in HIV-positive patients, respectively. Most orthodontists (92.9%) reported they needed to obtain more information about orthodontic care in patients with HIV/AIDS. Conclusion: Although orthodontists reported feeling able and qualified to provide dental care to patients with HIV/AIDS, gaps in their knowledge need to be addressed with further training

RESUMO

Bimaxillary protrusion is a clinical condition with high prevalence rate, which damages facial esthetics and affects the mental health of patients. Its clinical manifestations include protrusion of lips, overexposure of teeth, vertical and sagittal overdevelopment of alveolar bone in the anterior areas of upper and lower anterior jaws, and so on. The common protocols for the treatment of severe bimaxillary protrusion is orthodontic treatment with exaction of premolars or combined orthognathic-orthodontic treatment. However, either method is of great difficulty. By systematic mechanical design, the author used the treatment system of customized lingual appliances associated with corticotomy to realize the vertical and torque control of the anterior teeth, and obtain the orthodontic treatment effect of both esthetics and health. The clinical strategies for the treatment of severe bimaxillary protrusion were provided.

RESUMO

Orthodontic tooth movement inevitably affects adjacent periodontal tissue. The labiobuccal alveolar bone is generally thin, and patients with dental crowding often present alveolar dehiscence and fenestration. These may lead to prolonged treatment time, even gingival atrophy, tooth loosening and other complications in the orthodontic tooth movement. Periodontally accelerated osteogenic orthodontics (PAOO) could accelerate the orthodontic tooth movement and promote the formation of new bone by using corticotomy and bone grafting. This article, starting from the influence of orthodontic treatment on periodontal hard tissue, describes the application of PAOO in orthodontic treatment.

RESUMO

BACKGROUND: MicroRNAs (miRNAs) are non-coding short, single-stranded RNA molecules that may serve as biomarkers for various inflammatory and molecular mechanisms underlying bone and tissue remodeling consequent to orthodontic force application. METHODS: A thorough literature search in major databases was conducted in March 2021 to generate evidence for miRNAs in orthodontics, with prior PROSPERO registration. The initial search revealed 920 articles, subjected to strict selection criteria according to PRISMA, and resulted in final inclusion of four studies. Quality assessment by QUADAS-2 classified three studies as unclear risk-of-bias while the applicability was high. Further, bioinformatic analysis was performed to identify the target genes from the miRNA database (miRDB) and TargetScan databases and their protein-protein interaction pathways with the STRING analysis. RESULTS: Multiple miRNAs in gingival crevicular fluid (GCF) of orthodontic patients were seen, including miRNA-21, 27(a/b), 29(a/b/c), 34,146(a/b), 101, and 214 along with matrix metalloproteinases (MMPs)-1, 2, 3, 8, 9, 14 in one study. A statistically significant increase in expression of miRNA-29a/b/c,101, 21 from pre-treatment (before initiation of retraction) was seen to reach a peak at 4-6 weeks (wk) of retraction. On the contrary, miRNA-34a showed downregulation from the 1 day to 4 wk of retraction and also, negatively correlated with MMPs-2,9,14 levels at the same observation times. The distance of canine movement showed mild correlation with miRNA-27a/b, 214 at 2 wk of retraction. Bioinformatics revealed 1213 mutual target genes which were analyzed for inter-relational pathways using Cytoscape plugin, MCODE. Further, 894 prominent protein interactions were identified from the STRING database and SMAD4, IGF1, ADAMTS6, COL4A1, COL1A1, COL3A1, FGFR1, COL19A1, FBN1, COL5A1, MGAT4A, LTBP1, MSR1, COL11A1, and COL5A3 were recognized as the hub genes. Their interactions were able to isolate multiple miRNAs: hsa-miR-34a-5p, hsa-miR-29b-2-5p, hsa-miR-29b-3p, hsa-miR-34a-3p, hsa-miR-27a-5p, hsa-miR-29a-5p, hsa-miR-29b-1-5p, hsa-miR-29c-3p, hsa-miR-214-5p, hsa-miR-27a-3p, hsa-miR-29a-3p, hsamiR-146-5p, which were found promising as biomarkers for tooth movement. CONCLUSIONS: Our results support using miRNAs as biomarkers in varied orthodontic study designs and for inter-relationships with pathological settings like periodontal disease, pre-malignancies, or conditions like obesity or metabolic irregularities, etc. The identified target genes and their protein interaction pathways can be used to propose precision therapies, focusing on ideal tooth movement with minimal iatrogenic side-effects.

RESUMO

Introduction The Royal College of Surgeons of England (RCSEng) and the Royal College of Physicians and Surgeons of Glasgow (RCPSG) offer the bi-collegiate Membership in Orthodontics (MOrth) examination, a summative assessment of specialist knowledge, skill and behaviour in orthodontics. The COVID-19 pandemic has had a profound global effect on almost every facet of normal life, including the conduct of face-to-face examinations. We highlight development, implementation and feedback for the bi-collegiate MOrth Part 2 examination delivered remotely to a cohort of candidates in September 2020 by RCSEng/RCPSG.Methods Two anonymised online surveys (Google Forms) were distributed via electronic mail following completion of the examination diet. Forty-two candidates were sent a survey covering four domains and comprising a total of 31 questions. The 20 examiners were sent a survey containing eight questions. In both surveys, free-text responses were also collected. A rating system was used to categorise responses. All survey responses were summarised in an online data collection sheet.Results The response rate was 78.5% (33/42) and 75% (15/20) for candidates and examiners, respectively. Overall, favourable responses in relation to all sections of the assessment were elicited from candidates with the majority (mean 79.8%; 75.8-81.9%) reporting that the online examination format worked well. Equally, favourable responses were reported by examiners. Notably, 80% of examiners felt that the online exam style did not affect the mark a candidate would receive, and 100% were confident that the marks the candidates received were a reflection of their ability and were not affected by the online delivery of the assessment.Conclusions The feedback from both candidates and examiners relating to an online remote assessment of the bi-collegiate MOrth Part 2 was generally positive. Based on the survey responses, this format of a high-stakes examination was acceptable to all stakeholders, and demonstrated a high level of perceived validity and reliability in terms of content.

RESUMO

Artificial intelligence (AI) applications have significantly improved our everyday quality of life. The last decade has witnessed the emergence of up-and-coming applications in the field of dentistry. It is hopeful that AI, especially machine learning (ML), due to its powerful capacity for image processing and decision support systems, will find extensive application in orthodontics in the future. We performed a comprehensive literature review of the latest studies on the application of ML in orthodontic procedures, including diagnosis, decision-making and treatment. Machine learning models have been found to perform similar to or with even higher accuracy than humans in landmark identification, skeletal classification, bone age prediction, and tooth segmentation. Meanwhile, compared to human experts, ML algorithms allow for high agreement and stability in orthodontic decision-making procedures and treatment effect evaluation. However, current research on ML raises important questions regarding its interpretability and dataset sample reliability. Therefore, more collaboration between orthodontic professionals and technicians is urged to achieve a positive symbiosis between AI and the clinic.

RESUMO

PURPOSE: Teledentistry uses computer-based technology to render remote healthcare-related therapy and/or consultation. The purpose of this study was to review the contributions and concerns about the use of teledentistry in clinical orthodontics. MATERIALS AND METHODS: The focused question was "What are the benefits and limitations of the use of teledentistry in clinical orthodontics?" PubMed/Medline, Scopus, Embase, Google-Scholar and ISI Web of knowledge databases were searched up to and including February 2021 using the following key words: 1. teledentistry; 2. teleorthodontics; 3. ethics; 4. orthodontics; 5. SCOPE: The inclusion criteria were: (a) clinical studies; (b) case reports; and (c) case series. Studies on animal models, in vitro and/or ex vivo studies, letters, commentaries, and narrative and systematic reviews were not included in the search. The design of the study was tailored to recapitulate the relevant information. RESULTS: Four clinical studies fulfilled the eligibility criteria and were processed for data extraction. All studies had been performed after obtaining informed consent from the participants. Three studies reported that teledentistry was useful in clinical orthodontics. In one study, a clear conclusion could not be drawn regarding the benefits of teledentistry in clinical orthodontics. Two out of the four studies did not obtain prior approval from an institutional review board or ethics committee. Three studies did not report any measures that were undertaken to safeguard the electronic transfer of patient-related health information. CONCLUSIONS: Teledentistry is a useful tool for initial patient assessments; however, it is not a reliable alternative for in-office clinical orthodontic practice.

RESUMO

INTRODUCTION: Having a beautiful smile is the main desire of people seeking dental treatment. To achieve this goal, many variables must be considered. These include tooth alignment, color, shape and size, besides their harmonious relationship with the lips and face. An individualized diagnosis is essential to achieve the best result. Within this context, facial analysis and the characteristics of shape, size and position of maxillary incisors play a key role. METHODS: This paper describes clinical situations in which interdisciplinary treatment was performed to achieve esthetic results in a conservative manner and ensuring greater stability. In most cases requiring reshaping of maxillary incisors for esthetic reasons, prior orthodontic movement is essential. The main focus of this paper is to discuss the many variables involved in these situations. RESULTS AND CONCLUSION: The results of treatments described in this paper were obtained by means of a multidisciplinary approach, involving Orthodontics and Esthetic Dentistry, acting in harmony and recognizing their possibilities and limitations, in order to offer patients the best esthetic solution for their smile. The best treatment option is not always the easiest or fastest. The dentist, as a health professional, should consider the patients' wishes but also perform treatments with minimal intervention, and the best and most predictable esthetic result, also focusing on function and health.

RESUMO

OBJECTIVES: A novel magnetic resonance imaging (MRI) scan protocol is presented on the basis of ultra-short time to echo (UTE). By this MRI cephalometric projections (MCPs) can be acquired without the need of post processing in one shot. Different technical parameterizations of the protocol are performed. Their impact on the performance of MCPs is evaluated in comparison to the gold standard-the lateral cephalometric radiography (LCR) for cephalometric analysis (CA) in orthodontics. METHODS: Seven MCPs with various scan parameters influencing the scan duration and one LCR are used from one subject. 40 expert assessors performed CA for 14 predefined cephalometric landmarks. Relative metric distances and absolute angular measurements were calculated. Statistical analysis is presented and the deviations are highlighted to demonstrate the potential of the method for further analysis. RESULTS: The MCPs are acquired in 5-154 seconds, depending on resolution and contrast. Mean relative distances were 2.4-2.7 mm in MCPs and 1.6 mm in LCR, which demonstrate the accuracy and level of agreement of the expert assessors in identifying anatomical landmarks. In comparison to other studies, the presented MCP performed similar in angular analysis and demonstrated on average deviation of 1.2° ±1.1° in comparison to LCR. Despite the point articulare (Ar) and the related gonial angle the calculate distances and angles show outcomes in the range of ±2°/2mm. CONCLUSIONS: MCPs can be acquired much faster in comparison to other techniques known from literature for CA. This study demonstrated the potential of the new method and showed first feasible results. Further research is needed to analyze the performance on a broad range of patients.

RESUMO

Aims: The aim of this study is to evaluate the multidisciplinary treatment relationship between the two specialties of Dentistry, Departments of Periodontology and Orthodontics, by examining consultation request notes between the two departments. Materials and Methods: The consultation request notes of 1685 patients who were treated at Erciyes University Faculty of Dentistry were included in the study. All notes were analyzed retrospectively and divided into categories. While the consultation request notes of 446 patients from the Department of Periodontology (DP) to the Department of Orthodontics (DO) were evaluated, the consultation request notes of 1239 patients from DO to DP were evaluated. Pearson's Chi-Squared test was used in the cloud-based TURCOSA statistical software for the statistical analysis of the obtained data. Results: The highest number of requests for consultation from DP to DO was due to "Evaluation of the patient for orthodontic treatment (n = 203; 45.5%)," and the highest number of requests from DO to DP was "Gingival/Periodontal Treatment and Providing Motivation of Oral Hygiene (n = 558; 45.0%)". It was observed that most patients for whom consultation was requested were women (P < 0.05). Conclusions: This study determined the most common reasons for consultation requests between DP and DO and the sex which was the most prevalent. It was concluded that requests were made for the expertise of the other department for problems that could not be solved by the first department.

RESUMO

BACKGROUND: Coronavirus disease (COVID-19) has led to unprecedented challenges in the arts, sports, education, finance, and healthcare. The aim of this study was to compare demographic characteristics of new-patient visits for orthodontic treatment in the pandemic year (2020) versus previous years. METHODS: The retrospective study included patients who sought care at a tertiary orthodontic referral center between January 1, 2016 and December 31, 2020. Clinical and demographic characteristics, including age, age group (child, young adult, adult), gender, and numbers of monthly and annual new-patient visits were compared between the pre-pandemic (2017-2020) and post-pandemic (2020) periods. The daily average numbers of appointments were compared for 2019 versus 2020. RESULTS: The average number of monthly new-patient visits was 240.69 ± 81.48 in the pre-pandemic period, as opposed to 113.75 ± 88.89 in the year 2020 (P < 0.001). The average number of monthly new-patient visits decreased by 48.3% in 2020 compared to 2019, while the average number of daily new-patient visits in 2020 decreased significantly in all months (P < 0.05), except for January (P = 0.613) compared to the monthly numbers from the previous year. No significant difference was found between the pre-pandemic period and 2020 with regard to gender (P = 0.410). In all years, the numbers of new-patient visits were higher for women, compared with men, and for children, compared with adults. CONCLUSIONS: The results indicated a sharp decrease in the number of new-patient visits for orthodontic treatment in the pandemic year (2020) compared to previous years.

RESUMO

John Nutting Farrar (1839-1913) has been hailed as the 'father of American orthodontics' and his textbook, published in 1888, is often claimed to be the first devoted exclusively to orthodontics, while the American Emerson Angell is supposed to be the inventor of the orthodontic 'jackscrew'. However, the unknown Englishman Charles Gaine, identified by Lilian Lindsay in 1933 as the author of the first British orthodontic textbook, could be said to be the father of British orthodontics, as the publication of his book in 1858 and his demonstration of the screw appliance at the Great Exhibition of 1851 predated both these transatlantic events.

RESUMO

INTRODUCTION: Three-dimensional (3D) printing technologies are profoundly changing the landscape of orthodontics. To optimize treatment-oriented applications, dimensional fidelity is required for 3D-printed orthodontic models. This study aimed to evaluate the effect of build angle and layer height on the accuracy of 3D-printed dental models and if each of their influences on print accuracy was conditional on the other. METHODS: A maxillary cast was scanned using an intraoral scanner. One hundred thirty-two study models were printed at various combinations of build angle (0°, 30°, 60°, 90°) and layer height (20 µm, 50 µm, 100 µm) with a digital light processing printer (n = 11 per group). The models were digitally scanned, and deviation analyzed using a 3D best-fit algorithm in metrology software. RESULTS: A statistically significant interaction was consistently found between build angle and layer height for each positive deviation, negative deviation, and proportion out of bounds. Average deviations of all study models were within clinically acceptable ranges, but the least accurate models were printed at 0°/20 µm. Although there was a tendency for an oblique build angle of 30° or 60° with a smaller layer height of 20 µm or 50 µm to print the most accurate models, 95 % confidence intervals overlapped with all other angles and heights except for 0°/20 µm. CONCLUSIONS: Build angle and layer height have statistically significant interactive effects on the accuracy of 3D-printed dental models. Overall, digital light processing printers produced models within clinically acceptable bounds, but the choice of build angle and layer height should be considered in conjunction with the clinical application, desired print time, and preferred efficiency of each print job.

RESUMO

BACKGROUND: An alveolar cleft commonly affects 75% of cleft lip and palate patients. While it is common practice to provide a course of orthodontic treatment before alveolar bone grafting, there are no previous high-quality studies reporting on the benefits of this type of treatment. AIM: The aim of the study is to evaluate the effectiveness of pre-alveolar bone graft orthodontics for unilateral non-syndromic cleft palate patients. METHOD: The PABO trial is a multicentric, parallel, two-arm, single-blinded randomised controlled trial. The inclusion criteria include unilateral cleft alveolus patients requiring bone graft and between the age group of 8 and 13 years with erupted upper central incisors. Participants will be recruited at three centres across India. Participants will be randomised to orthodontic treatment or no orthodontic treatment group. Both groups of participants will have alveolar bone graft surgery and will be followed up for 6 months after surgery. The primary outcome will be the success of the alveolar bone graft measured by anterior oblique radiograph and secondary outcomes include quality of life, cost analysis and quality of the dento-occlusal outcome. Data analysis will be carried out by an independent statistician at the end of the study. DISCUSSION: This study is the first to evaluate the effect of orthodontics on alveolar bone graft success. The increased burden of care for these patients with multiple treatments required from multiple specialists from birth to adult life highlights the need for reducing unnecessary treatment provision.
