Knowledge and Perception of Orthodontic Treatment among General and Non-Orthodontic Dental Specialists: A Comparative Study. Healthcare (Basel) 2023; 11:healthcare11030340. [PMID: 36766915 PMCID: PMC9914675 DOI: 10.3390/healthcare11030340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 01/08/2023] [Accepted: 01/10/2023] [Indexed: 01/27/2023] Open
Abstract
The objective of this study is to discover any possible association of gender or practitioner classification with orthodontic knowledge and attitudes towards orthodontic treatment. Descriptive cross-sectional research was conducted on two groups of dentists in the Ha'il region of Saudi Arabia. Group I included general practitioners, while Group II had non-orthodontic specialists. The findings suggest a statistically significant (p < 0.05) difference between the knowledge and attitudes of general practitioners and non-orthodontic specialists. Independent two tailed t-scores for difference in Knowledge (t-score = 3.19919, p = 0.003) and Attitude (t-score = 2.16314, p = 0.048319), highlight significant disparities in the knowledge and attitudes of general practitioners and non-orthodontic specialists. However, no statistically significant difference was observed in terms of knowledge and attitudes based on gender differences. This study captures and highlights subtle information that is very significant in dealing with critically important orthodontics issues. The study suggests that it is possible that a non-orthodontic specialist may suggest an altogether different line of treatment with different consequences when compared to a general practitioner and vice versa. This may result in unwanted, permanent orthodontic effects, highlighting the significance of the early stage of orthodontic treatment awareness. This research reveals disparities between the perceptions of general practitioners and non-orthodontic specialists about the stage and relevance of orthodontic treatment. It is strongly advised to see an orthodontic expert rather than a general practitioner or non-orthodontic specialist for orthodontic issues.

[PMID: 35835702 DOI: 10.1016/j.ajodo.2022.06.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Revised: 06/06/2022] [Accepted: 06/06/2022] [Indexed: 11/01/2022]
Abstract
INTRODUCTION This study aimed to evaluate the content, reliability, and quality of YouTube videos for early orthodontic treatment. METHODS YouTube video searches were carried out using the keyword "early orthodontic treatment," which was determined using Google Trends. After sorting according to relevance, the first 120 videos were observed, and 61 videos were analyzed accordingly. Further, the general characteristics, uploader source, reliability score (RS), global quality scale (GQS), video information quality index, audiovisual quality, viewers' interaction index, viewing rate, and total information content score (TCS) data belonging to these videos were analyzed. Based on their reliability scores, videos were divided into 2 main groups (low and medium/high information content) accordingly. RESULTS It was found that 25 (41%) of the videos had medium/high information content, and 36 (59%) had low information content, respectively. Videos with medium/high information content were found to have long video durations, increased comments, and high TCS, GQS, RS, and video information quality index scores (P <0.05). The videos uploaded by doctors had increased comments, long duration, and high TCS, GQS, and RS scores (P <0.05). CONCLUSIONS The quality of the information provided by YouTube videos on early orthodontic treatment was generally insufficient. In addition, the information quality was high for videos uploaded by doctors.

Abstract
BACKGROUND Elastodontics is a specific interceptive orthodontic treatment that uses removable elastomeric appliances. They are functional appliances that produce neuromuscular, orthopedic and dental effects. Thus, these devices are useful in the developmental age, when skeletal structures are characterized by important plasticity and adaptation capacity, allowing to remove factors responsible for malocclusions. Elastomeric devices are generally well tolerated by patients requiring simple collaboration and management. This work can be useful to update all orthodontists already adopting these appliances or for those who want to approach them for the first time. This study aimed to describe four cases treated with new elastomeric devices called AMCOP Bio-Activators and to provide an overview of elastodontics, its evolution, indications and limits. METHODS A total of four clinical cases were presented after a treatment period of 16-20 months to evaluate the clinical and radiological effects of the elastodontic therapy. RESULTS The effectiveness of Bio-Activators on clinical cases was evidenced with a significant improvement in skeletal and dentoalveolar relationship, and malocclusion correction in a limited treatment period (16-20 months). CONCLUSIONS The Bio-Activators showed clinical effectiveness to achieve therapeutic targets according to a low impact on the patient's compliance.

Individualized 3D-Printed Bone-Anchored Maxillary Protraction Device for Growth Modification in Skeletal Class III Malocclusion. J Pers Med 2021; 11:jpm11111087. [PMID: 34834439 PMCID: PMC8619151 DOI: 10.3390/jpm11111087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 10/18/2021] [Accepted: 10/23/2021] [Indexed: 11/17/2022] Open
Abstract
Bone-anchored maxillary protraction (BAMP) is effective for skeletal Class III malocclusion. However, infection, screw and plate loosening, and device failures occur with conventional plates. This pilot prospective study analyzed the feasibility of individualized BAMP using preoperative simulation and 3D titanium printing in patients referred by the orthodontic department for four BAMP miniplates. Preoperative cone beam computed tomography data were analyzed using CAD/CAM software to fabricate the individualized 3D-printed BAMP device. The customized plates were printed using selective laser sintering and inserted onto the bone through an adjunct transfer jig. The accuracy of preoperative simulation and actual placement of the BAMP device were tested by superimposing simulated positioned digital images and postoperative computed tomography data. The growth modification effect depended on superimposition of lateral cephalograms and comparative changes in SNA, SNB, ANB, and Wits. Two male patients were finally included in the study. BAMP decreased the ANB difference (−4.56 to −1.09) and Wits appraisal (−7.52 to −3.26) after 2 years. Normal measurement indices for sagittal and vertical growth indicated successful growth modification. The mean accuracy between preoperative simulation and actual surgery was 0.1081 ± 0.5074 mm. This treatment modality involving preoperative simulation and 3D titanium printing for fabricating and placing customized BAMP devices precisely at planned locations is effective for treating skeletal Class III malocclusion.

Abstract
The orthodontic management of patients with Class III malocclusion poses numerous prognostic and treatment challenges to the clinician. Various removable, orthopaedic, myofunctional and fixed appliances have been recommended for the correction of Class III malocclusion. The Reverse Twin Block (RTB) is a simple and well tolerated appliance which has often been used for the early management of such cases in mixed dentition. Cases reporting use of RTB in permanent dentition are however, limited. This article presents an insight into the encouraging results of reverse twin block (RTB) appliance used in conjunction with fixed mechanotherapy for the successful treatment of a 12-year-old patient presenting with skeletal Class III malocclusion and a concave facial profile. The RTB appliance helped establish a favourable environment for unrestricted maxillary growth, at the same time redirecting the mandibular growth to a clockwise direction and correcting the incisal relationship. The favourable treatment outcome and long-term stability achieved substantiates the feasibility of RTB appliance in mild to moderate skeletal Class III malocclusions in permanent dentition cases.

Abstract
The present study aimed to assess the perception and knowledge of Brazilian orthodontists on the ideal moment to treat Class II malocclusions. Questionnaires with open, semi-open and close questions were sent by e-mail to 1653 Brazilian orthodontists. These orthodontists were registered in the Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR). One-hundred and three (9.86%) Orthodontists replied to the questionnaires. Most of them were males (60.5%) with specialization as the highest level of professional qualification (59.9%). Most of the orthodontists (51%) reported preference for treating Class II malocclusions in late mixed dentition, followed by the early mixed dentition (29%). The age range between 10 and 12 years old figured as the most prevalent in patients searching for treatment (42.7%). Most of the patients searching for treatment were females (69.7%). Preferences for functional orthopedic appliances were reported by 35% of the orthodontists. Brazilian orthodontists revealed a trend for treating patients with Class II malocclusions in the late mixed dentition. Female patients aged from 10 to 12 years old represented the majority of patients that search for orthodontic treatment. Functional orthopedic appliances were preferred by Brazilian orthodontists for treating Class II malocclusions.

Abstract
Deleterious oral habits, such as non-nutritive sucking or tongue thrusting, if not intercepted at an early stage can cause complex malocclusions. This manuscript describes a clinical case report of a successful interception of a severe anterior dental open bite caused by thumb sucking and tongue thrusting habits. The case involved a six-year-old female patient treated with the use of palatal spurs and maxillary removable crib followed by monitoring the development of dental occlusion. At the end of the interceptive phase acceptable results were achieved, showing the efficacy of the treatment undertaken as well the importance of an early intervention to remove harmful oral habits.

Abstract
INTRODUCTION The aims of this study were to establish the prevalence of dental features that indicate a need for early intervention and to ascertain the prevalence of different methods of early treatment among a population of Nigerian children in mixed dentition. METHODS Occlusal relationships were evaluated in 101 children in mixed dentition between the ages of 6 and 12 years who presented at the Orthodontic Unit, Department of Child Dental Health, Lagos University Teaching Hospital over a 2 years period. The need for different modes of early orthodontic treatment was also recorded. RESULTS Anterior tooth rotations (61.4%) and increased overjet (44.6%) were the most prevalent occlusal anomalies. Others included deep bite (31.7%), reverse overjet (13.9%), and anterior open bite (14.8%). Severe maxillary spacing and crowding were exhibited in 12.0% and 5.0%, respectively. About a third (35.7%) of the subjects presented with crossbite while lip incompetence was observed in 43.6% of the subjects. About 44% of the subjects also presented with various oral habits with digit (15.8%) and lip sucking (9.9%) being the most prevalent. Subjects were recommended for treatment with 2 by 4 fixed orthodontic appliances (22.3%), habit breakers (20.7%), removable orthodontic appliances (16.5%), and extractions (15.7%). CONCLUSIONS Increased overjet and anterior tooth rotation were the majority of occlusal anomalies seen, which are not only esthetically displeasing but may also cause an increased susceptibility to trauma to these teeth. Treatment options varied from extractions only to the use of appliance therapy.

Abstract
The aim of this article is to show the use of the Balters' Bionator in pseudo-Class III treatment. The importance of differentiating between true Class III and pseudo-Class III is emphasized. The therapeutic results of a Balters' Bionator appliance are presented in three case reports of subjects in the mixed dentition. In this stage of development it is possible to correct an isolated problem. The use of the Bionator III in this kind of malocclusion enabled the correction of a dental malocclusion in a few months and therapeutic stability of a mesially-positioned mandible encouraging favourable skeletal growth.

Abstract
Among the commonly encountered dental irregularities which constitute developing malocclusion is the crossbite. During primary and mixed dentition phase, the crossbite is seen very often and if left untreated during these phases then a simple problem may be transformed into a more complex problem. Different techniques have been used to correct anterior and posterior crossbites in mixed dentition. This case report describes the use of hexa helix, a modified version of quad helix for the management of anterior crossbite and bilateral posterior crossbite in early mixed dentition. Correction was achieved within 15 weeks with no damage to the tooth or the marginal periodontal tissue. The procedure is a simple and effective method for treating anterior and bilateral posterior crossbites simultaneously.

Abstract
Time can be considered the fourth dimension in dento-facial orthopedics. Treatment timing can play a significant role in the outcomes of treatment aimed to produce an orthopedic effect in the craniofacial structures. The results of methodologically-sound cephalometric studies of both the past and the recent history of orthodontics clearly indicate that optimal treatment timing for Class II skeletal disharmony with a functional appliance (e.g. twin block) is during or slightly after the peak in mandibular growth as revealed by a reliable biologic indicator of individual skeletal maturity such as the cervical vertebral maturation method.

Abstract
O objetivo desse estudo foi elaborar um protocolo de assistência ortodôntica em saúde coletiva. Um programa de prevenção e interceptação ortodôntica foi sugerido, com a inclusão de atitudes que visem à prevenção das oclusopatias em programas de saúde já existentes e a ampliação da oferta de serviços nas UBSs, abrangendo a instalação de mantenedores de espaço e procedimentos interceptores. Os possíveis problemas oclusais a serem abordados no programa interceptor foram discutidos e classificados em prioridades primária e secundária de atendimento, enfatizando os desvios oclusais que não deveriam ser tratados precocemente. A idade sugerida para abordagem seria a correspondente à da dentição decídua e início da dentição mista. A organização e inclusão de procedimentos ortodônticos são possíveis de ser aplicadas com o gerenciamento dos recursos físicos, humanos e financeiros e o estabelecimento de critérios para acesso aos serviços. A utilização de protocolo de assistência e o correto planejamento das ações ortodônticas podem possibilitar a realização de ações preventivas e interceptoras nas próprias UBSs, enquanto maiores recursos possam ser alocados para a criação de Centros de Referência de Especialidades, com a possível implantação de procedimentos em Ortodontia Corretiva.

Abstract
It would be of benefit to have a better understanding of the relative effects of genetics and environmental factors on craniofacial parameters when undertaking orthodontic therapy and treatment planning. However, there is a lack of such information in pre-adolescents. The aim of this study was to verify the degree of genetic and environmental contribution to the growth of the facial skeleton in twins aged 6 to 12 years. The material comprised the lateral cephalograms of 89 pairs of female twins in Beijing, China, of whom 61 pairs were diagnosed by DNA analysis as monozygotic (MZ) and 28 pairs as dizygotic (DZ). Four main groups (with a starting age of 6, 7, 9 and 11 years) were studied in a semi-longitudinal manner, with a sub-group further investigated for 2-4 consecutive years. The total sample therefore consisted of 183 pairs (MZ 110, DZ 73) aged from 6 to 12 years. The depths of the cranial base, mid and lower face were measured, as well as anterior and posterior face height. A two-tailed t-test showed significant environmental effects on lower face depth (P < 0.01), whilst genetic effects on face height were also significant (P < 0.01). The results suggest that early orthodontic intervention would have a greater influence on the antero-posterior rather than on the vertical plane of growth.

Abstract
The principal aims of this study were to find the cephalometric predictors for good treatment results of bionator therapy and to justify bionator therapy as an early phase I treatment for patients with Class II Division 1 malocclusion. Forty subjects who had Class II Division 1 malocclusion and who were treated with the bionator were selected for this study. They were classified into a good treatment result group and a poor treatment result group in reference to the posttreatment molar relationship, posttreatment overbite and overjet, posttreatment profile, and existence of relapse. Thirty-one cephalometric variables were analyzed on the pretreatment lateral cephalograms by t-test to evaluate differences between the 2 groups. The variables that differed significantly were analyzed by discriminant analysis to assess their predictability. The study showed that horizontal growth pattern, close to normal anteroposterior relationship between the maxilla and mandible, upright mandibular incisor, and retrusive lower lip were important predictors for good results. In particular, protrusion of the lower lip was the most important factor for the determination of the treatment results. In addition, the treatment times were much shorter for patients with these good predictors. The present study supports the premise that bionator therapy can produce clinically stable and favorable results if the patients are appropriately selected with the use of these diagnostic criteria.
