RESUMO

The fusion of orthodontic treatment and periodontal tissue-regeneration therapy has attracted attention. However, regenerated bone has a higher density than physiologic bone, which may cause problems including root resorption or stagnation of orthodontic movement. Therefore, the optimized periodontal regeneration for orthodontic movement (O-PRO) approach was developed with the aim of regenerating periodontal tissues with sparse bone quality. Unlike conventional methods, this concept is specifically suited for orthodontic movement. A new classification for the preoperative evaluation of periodontal tissues was also devised, and results are reported from cases where orthodontic treatment was implemented using each type of O-PRO method.

RESUMO

In 2018, a new « Classification of Periodontal and Peri-implant Diseases and Conditions ¼ was adopted by the American Academy of Periodontology and the European Federation of Periodontology. Numerous studies in recent years have improved the understanding of periodontal diseases and their risk factors, leading to an update of the 1999 classification. Among the major changes is the development of a classification of periodontitis into different stages and grades and the notion of periodontal health, an essential prerequisite for orthodontic treatment. Based on the analysis of the 24 published articles, this work provides explanations regarding the main changes that orthodontists may face. The classification of Chicago precisely defines periodontal health and proposes a new system for characterizing periodontitis in stages and grades. It then becomes a valuable aid for the orthodontist in risk detection and periodontal screening. The knowledge of this new classification is essential for reliable communication between dentists, periodontists and orthodontists, in order to guarantee the success of orthodontic treatment.

RESUMO

For several decades, orthodontists and periodontists have repeated that orthodontics have no harmful consequences on the periodontium when it is healthy or treated. However, a systematic review of the literature undermines this common refrain and concludes that there is a lack of reliable evidences of the positive effects of orthodontics on periodontal health with, in the best periodontal conditions, slight adverse effects. It is therefore the responsibility of orthodontists to keep the periodontal cost of orthodontic treatment as low as possible. How to make sure that this « at best ¼ does not turn into an « at worst ¼ ? In order to minimize the deleterious consequences of orthodontic treatment on the periodontium, the orthodontist must be able to specify which patients she/he can immediately consider providing orthodontic treatment and those on whom periodontal treatment is mandatory before all. The orthodontist must therefore transform, for a few minutes, into a periodontist in order to recognize the eight signs of loss of attachment and the six risk factors for periodontitis, exposed in this article. Both needs for periodontal and orthodontic treatment have to be measured and would not be efficient without the patient's and the practitioners' motivation.

RESUMO

The objective of this comparative retrospective cohort performed on 202 patients was to evaluate the influence of instrumental extraction (forceps, suction cup, spatula) during delivery on the need for orthodontic treatment. Questionnaires on the type of delivery were distributed in three different structures. The need for treatment was assessed using the IOTN indicator (Index of Orthodontic Treatment Need). The groups were compared by statistical tests at the significance level of 5 %. 202 patients were included (51 in the group « instrumental delivery ¼, 151 in the control group). With an average IOTN of 3.3 in the « instrumental delivery ¼ group versus 2.5 in the « non-instrumental delivery ¼ group, the difference between the two groups is statistically significant (p = 0.00015). Since the need for orthodontic treatment is significantly higher in patients born by instrumental delivery compared to patients born without instrumental support, instrumental extraction is therefore a risk factor in orthodontics, diagnosis and orthodontic treatment may be indicated in these patients. In addition, provided that it is proven effective, early osteopathic management may be recommended.

RESUMO

The aim of this study was to describe a surgical technique that can be used to solve dentofacial deformities in cleft palate patients with maxillary hypoplasia in order to increase maxillary alveolar bone width, without modifying the skeletal base, and therefore, keeping the velopharyngeal function unaltered. Four patients with a history of cleft palate not associated with syndrome and treated under conventional surgical protocol during their childhood, underwent PAOO surgery incorporating L-PRF, followed by an accelerated orthodontic treatment with checkups every two weeks. All patients reached the desired occlusion without modifying their skeletal bases and velopharyngeal function. Orthodontic treatments were finished between 10 and 14 months after surgery without complications. There were no observed complications in the velopharyngeal postsurgical function and an increase in the arch width was achieved in all cases, along with a reduced orthodontic treatment time. The clinical results obtained confirm that PAOO technique is a safe and reliable complement to orthognathic surgery in the surgical treatment of cleft patients. By increasing the perimeter of the maxillary dentoalveolar ridge, the segmentation of the maxilla could be avoided, increasing the post operatory stability of these patients.

RESUMO

AIM: To systematically review the comparative differences in the performance and timeliness of conventional orthodontic treatment with that of corticotomy-assisted accelerated orthodontic treatment. DATA SOURCES: The electronic databases PubMed and Google Scholar were searched from January 2007 to January 2018 in English, with manual searches of reference lists and gray literature. Thirty-six articles were included in the study with inclusion criteria as prospective clinical studies of patients treated with fixed conventional appliance and the intervention was the corticotomy-assisted accelerated orthodontic treatment method. STUDY SELECTION: Two reviewers assessed independently the eligibility of the included articles. One investigator abstracted study design information, intervention details, and harms data from all included studies into a standardized evidence table. The accuracy of these data was checked by the second investigator. We resolved any disagreements through discussion with other authors. RESULTS: Different aspects of the corticotomy-assisted accelerated orthodontics treatment method were investigated including risk factors, advantages, and disadvantages as compared to that of conventional orthodontic treatment. CONCLUSION: There is limited available evidence about effectiveness of corticotomy-assisted accelerated orthodontics. Although the current review indicates that the corticotomy-assisted accelerated orthodontic treatment method can fasten the treatment duration by 2.2-3 folds compared to conventional orthodontic treatment, furthermore, the level of evidence needs well-conducted prospective research with big sample size to draw valid conclusions. CLINICAL SIGNIFICANCE: Orthodontic treatment is a time-consuming process and due to noncompliance of patients, research has found different methods to accelerate the treatment, thus reducing the total treatment duration. Use of accelerated orthodontic techniques is expected to help clinicians in better treatment decisions for noncompliant patients.

RESUMO

The idea of a global orthodontic organization, the World Federation of Orthodontists (WFO), made up of national and regional orthodontic organizations, was realized in 1995 in San Francisco at the 4th International Orthodontic Congress that was held in conjunction with the 95th annual American Association of Orthodontists meeting. This umbrella organization strives to promote quality orthodontic care, practiced and delivered by orthodontic specialists in all parts of the world. In addition, it supports its member organizations with governing principles that promote appropriate membership criteria, qualified individual leadership participation, and long-term stability of the organization over time. In response to the Coronavirus Disease 2019 pandemic, the WFO has responded proactively and plans to augment its digital resources even further in the near future. This article describes the formation of the organization, the idea that germinated through the first three international orthodontic congresses, its workflow and membership criteria, the accountability and commitment it has toward its affiliates and individual members, and its plans for future years to come.

RESUMO

AIM: This literature review aims to update the evidence for prevention of white spot lesion (WSL) using orthodontic sealants among patients with fixed orthodontic appliances. BACKGROUND: As a major issue among orthodontists, prolonged treatment duration increases the risk of plaque development around orthodontic brackets and bands. In consequence, this can lead to heightened risk for caries development and higher possibility of WSL development around fixed orthodontic brackets. RESULTS: Increased prevalence of WSLs generally occurs during orthodontic treatment. This review explored various products of orthodontic sealants used to prevent WSL. Orthodontic sealants do not require patient compliance and thus will further lessen the burden among orthodontists as well as support enamel surface for a long period of time during treatment. Certain factors, however, are considered important in the efficacy of these sealants, such as antibacterial activity, color stability, resistance to acid and brush abrasion, and their effect on shear bond strength (SBS). CONCLUSION: The review showed that the use of orthodontic sealants in preventing WSLs during and after fixed orthodontic treatment is significantly effective. However, the bioactive glass is deemed more effective against WSL development due to its ability to immediately repair enamel surface, low cytotoxicity, and high biocompatibility. Moreover, clinical studies on bioactive glass are still needed to determine its acceptability among patients with fixed orthodontic appliance. CLINICAL SIGNIFICANCE: Development of WSL around the orthodontic brackets during treatment is a difficult task among orthodontists. As such, this review explored various strategies to effectively combat WSL development for good oral health and esthetics during orthodontic treatment.

RESUMO

Objective: To investigate of effects of using phase-contrast video technique on education in oral hygiene training. This one blind, parallel randomized controlled trial was conducted in a tertiary clinic. Fifty-three patients who presented to the orthodontics department aged 12-20 years were divided into two groups randomly by computer-generated assigned codes to receive oral hygiene education. The participants were blinded to type of education method. Before orthodontic therapy, the control group was trained only by the conventional method, while the test group was trained by phase-contrast video microscopy method in addition to conventional method. Some images and videos of moving microorganisms in dental plaque were shown to the patients in test group on a computer monitor. Subjects and Methods: The bacterial count, plaque index, and gingival index scores were compared. Measurements were obtained in baseline and follow-ups which were repeated with 1-month intervals after the training. Results: The plaque index scores (1.05 ± 0.1 vs. 1.43 ± 0.2; P < 0.001) and gingival index scores (0.90 ± 0.1 vs. 1.14 ± 0.2; P < 0.001) in test group was statistically lower than those in control group at the end of the study. The gingival index scores reduced by 39% in test group vs. 14% in control group. The number of bacteria significantly decreased in the group trained with phase-contrast video microscope technique (8,059,133 ± 3016 vs. 10,830,600 ± 4919; 0.018). Conclusions: The training with phase-contrast microscopy has a more positive effect than the traditional method in oral hygiene education.

RESUMO

BACKGROUND: The aim of this study was to evaluate the impact of clinical closure and delayed orthodontic care delivery in terms of types of emergencies, pain intensity, and disability experienced by orthodontic patients during the COVID-19 pandemic. METHODS: This was a descriptive cross-sectional study using an electronic survey that was distributed to orthodontic patients who were not seen in clinic for 2 to 3 months due to clinic closure. The survey included demographics, types of orthodontic emergencies, Numerical Rating Scale, and Manchester Orofacial Pain Disability Scale. RESULTS: There were a total of 150 respondents with mean age of 20 years; 57.33% were female patients. The most common reported orthodontic emergencies were poking wire 30%, debonded brackets 27.3%, bad odor 24%, sharp ligature tie 20%, inflammation and bleeding 9.3%, ulcer 8.7%, and problematic palatal device 8%. Pain was significantly associated with poking wire (P < 0.001), sharp ligature tie (P < 0.01), ulcer (P < 0.05), and problematic palatal device (P < 0.01). Poking wire, sharp ligature tie, and problematic palatal device were found to be significant predictors of pain intensity. Median pain intensity was 3, similar to the median disability score. There was a significant association between pain intensity and disability score (P < 0.01). With each unit increase in pain intensity, the disability score increased by 1.18. CONCLUSIONS: Delay in receiving orthodontic care could result in an orthodontic emergency, yet pain and disability resulting from these events are minimal. The decision to resume clinical service should be evaluated considering risks and benefits in case of the pandemic. Further studies are required.

RESUMO

In 2019, the Board of Trustees of the American Association of Orthodontists asked a panel of medical and dental experts in sleep medicine and dental sleep medicine to create a document designed to offer guidance to practicing orthodontists on the suggested role of the specialty of orthodontics in the management of obstructive sleep apnea hypopnea syndrome. The present article aimed to provide interpretation of this White Paper, and to further help Chinese orthodontist to understand it.

RESUMO

INTRODUCTION: A diverse range of outcomes is used in orthodontic research with a focus on measuring outcomes important to clinicians and little consistency in outcome selection and measurement. We aimed to develop a core outcome set for use in clinical trials of orthodontic treatment not involving cleft or orthognathic patient groups. METHODS: A list of outcomes measured in previous orthodontic research was identified through a scoping literature review. Additional outcomes of importance to patients were obtained using qualitative interviews and focus groups with adolescents aged 10-16 years. Rating of outcomes was carried out in a 2-round electronic Delphi process involving health care professionals and patients using a 9-point scale. A face-to-face meeting was subsequently held with stakeholders to discuss the results before refining the core outcome set. RESULTS: After triangulation, a final list of 34 outcomes grouped under 10 domains was obtained for rating in the e-Delphi surveys. Fifteen outcomes were voted "in" after the second Delphi round involving 274 participants with a further outcome being included after the consensus meeting. These were subsequently refined into a final set of 7 core outcomes, including the impact of self-perceived esthetics, alignment and/or occlusion, skeletal relationship, stability, patient-related adherence, breakages, and adverse effects on teeth or teeth-supporting structures. CONCLUSIONS: A bespoke orthodontic core outcome set encompassing both clinician- and patient-focused outcomes was developed. Incorporating this is the first step into providing a more holistic assessment of the impact of treatment while allowing for meaningful comparisons and synthesis of results from individual trials.

RESUMO

The purposes of this study were to investigate the influence of the orthodontics-first approach (OFA) and surgery-first approach (SFA) on changes in the signs and symptoms of temporomandibular joint disorders (TMDs) and to compare pre- and postoperative orthodontic treatment duration and total treatment duration between the two approaches. This retrospective study recruited 182 adult patients with malocclusions treated with OFA and SFA and recorded variables such as age, gender, skeletal classification, and signs and symptoms of TMD (clicking and pain disorders) before the start of the surgical-orthodontic treatment and after surgery. Changes in the signs and symptoms of TMD and treatment duration were evaluated within each approach and compared between two approaches. A binary logistic regression was performed to assess the influence of the variables on the postoperative signs and symptoms of TMD. There were no significant postoperative changes in temporomandibular joint (TMJ) pain for OFA and SFA, whereas a significant reduction was found in TMJ clicking after surgery for both approaches. According to binary logistic regression, the type of surgical-orthodontic treatment (OFA or SFA) was not a significant risk factor for postoperative TMJ clicking and pain, and the risk of postoperative TMJ clicking and pain was significant only when TMJ clicking (OR = 10.774, p < 0.001) and pain (OR = 26.876, p = 0.008) existed before the start of the entire treatment, respectively. With regard to the treatment duration, SFA (21.1 ± 10.3 months) exhibited significantly shorter total treatment duration than OFA (34.4 ± 11.9 months) (p < 0.001). The results of this study suggest that surgical-orthodontic treatment using SFA can be a feasible option of treatment for dentofacial deformities based on the equivalent effect on TMD and shorter overall treatment period compared to conventional surgical-orthodontic treatment using OFA.

RESUMO

INTRODUCTION: The present study aimed to evaluate the most common urgencies and emergencies in orthodontics during the coronavirus disease 2019 (COVID-19) pandemic and to assess how orthodontists in Brazil were dealing with patients and challenges. METHODS: Early in 2020, as the COVID-19 pandemic spread around the world, routine dental care was suspended in many countries, and only patients needing urgent or emergency care could be seen. During this period, orthodontists in Brazil were invited to participate in an anonymous online survey. Over 48 hours (May 1-3, 2020), 395 orthodontists (specialists, MScs, and PhDs) responded. They answered questions regarding dental office and appointments during the pandemic, the type of urgency or emergency care provided, the type of appliance and urgencies, etc. The level of concern about the impact of the pandemic on patients' orthodontic treatments and the financial impact on the dental office was also evaluated. Descriptive statistics were performed with percentages, and responses were compared between specialists, MScs, and PhDs, using chi-square tests. RESULTS: Specialists were the majority of respondents. Most orthodontists were handling only emergencies or urgencies. The most frequent urgencies were bracket breakage, archwire breakage, and breakage of molar tubes and/or bands. Stainless steel fixed appliances were the most common type of appliance related to unscheduled appointments. The majority of patients got in touch with the orthodontist using the professional WhatsApp messenger (WhatsApp Inc, Menlo Park, Calif). Orthodontists were more concerned with the financial impact of the pandemic than with the orthodontic treatment itself. CONCLUSIONS: Breakage of brackets, archwires, or tubes and/or bands were the most common causes of urgency and/or emergency appointments during the pandemic. The level of concern about the financial impact of the stay-at-home orders and the COVID-19 pandemic was significantly greater for specialists and MScs than for PhDs.
