Body image perception plays an important role in seeking orthodontic treatment. Body dysmorphic disorder (BDD) is a psychological condition where an individual constantly focuses on flaws in their appearance. This study aimed to assess BDD in adult orthodontic treatment candidates according to the index of treatment need (IOTN) in Qazvin city in 2020. This descriptive study was conducted on 404 eligible patients over 18 years of age presenting to dental clinics in Qazvin seeking orthodontic treatment. The patients were categorized according to their IOTN (grades 1–5) and filled out the Body Deformation Metacognition Questionnaire (BDMCQ). Data were analyzed by t-test and Analysis of Variance using the Statistical Package for the Social Sciences. Of all the patients, 50.2% were grade 1 (no need for treatment),and 1.5% were grade 5 (very great need for treatment). Furthermore, 54.5% of patients had severe BDD. BDD had no significant correlation with gender or marital status (P > 0.05). BDD was significantly correlated with age, educational level, and IOTN grade (P < 0.05). The present results revealed that over 50% of patients seeking orthodontic treatment did not need treatment, according to the IOTN. Dental clinicians are advised to be more careful in accepting patients with a history of psychological problems and numerous surgical procedures who seek cosmetic treatments.

This study aims to investigate the success rate of orthodontic traction of impacted teeth using the gold chain bonding (GCB) procedure significantly higher odds of success than older patients (P = 0.0099, odds ratio = 0.897). The success rate was highest for the upper lateral incisors (97.4%) followed by upper central incisors (94.7%). The success rate of surgical re-intervention of GCB procedure was 69%. Orthodontic patients underwent the GCB procedure at the National Dental Centre Singapore (NDCS) between 2014 and 2021. The sample comprised 495 teeth from 421 patients (238 male, 257 female; median age 14; range 7 -38 years). The historical records of these patients’ orthopantomograms and electronic medical records were reviewed to collect data on age, gender, ethnicity, tooth type, and surgical re-intervention. The success rate was calculated and compared using chi-square test and logistic regression analysis. The level of significance was set at P < 0.05. The overall success rate of the GCB procedure was 93.3%. There was no significant difference in the success rates between male (92.9%) and female (93.8%) patients (P = 0.779) or between Chinese (93.2%), Malay (94.4%), and Indian (91.7%) patients (P = 0.664). Younger patients have significantly higher odds of success than older patients (P = 0.0099, odds ratio = 0.897). The success rate was highest for the upper lateral incisors (97.4%) followed by upper central incisors (94.7%). The success rate of surgical re-intervention of the GCB procedure was 69%. Gold chain bonding is a highly predictable procedure for orthodontic treatment of impacted teeth with a high success rate especially in younger patients. Gender and ethnicity do not significantly affect the success rate.

The objective of this study was to determine if mandibular canine development is an indicator of maxillary cleft site canine development. A cross-sectional chart review with analysis of cone-beam computed tomography (CBCT) imaging of patients aged 7–12 with a unilateral complete cleft lip and palate who received alveolar bone graft surgery from January 2009 to January 2019. Three-dimensional (3D) measurements of the cleft site canine and ipsilateral mandibular canine were taken. A two-dimensional image was created from the 3D CBCT to simulate a traditional panoramic radiograph. Descriptive statistics and multivariable linear regression analyses were conducted, adjusting for age and gender. Pearson and Spearman correlations were calculated. The main outcome measure was the mandibular canine crown-to-root ratio (C:RR) compared to that of the maxillary cleft site canine C:RR. Five hundred and thirteen patients were reviewed, of which 78 met the inclusion criteria. Adjusting for age and gender, every unit change in mandibular canine C:RR corresponds to 0.69 (95% confidence interval [CI] = 0.42–0.95) change in maxillary canine C:RR, up to a mandibular canine C:RR of 3. Beyond a mandibular C:RR of 3, no change in the maxillary canine C:RR was observed (−0.02; 95%CI = −0.27–0.24). Pearson correlation coefficient was r = 0.65, and the Spearman correlation was P = 0.75. Mandibular canine C:RR is correlated to maxillary cleft site canine C:RR when the mandibular canine C:RR is ≤3.

The purpose of this study was to compare the predictive ability of different convolutional neural network (CNN) models and machine learning algorithms trained with frontal photographs and voice recordings. Two hundred and thirty-seven orthodontic patients (147 women, 90 men, mean age 14.94 ± 2.4 years) were included in the study. According to the orthodontic patient cooperation scale, patients were classified into two groups at the 12th month of treatment: Cooperative and non-cooperative. Afterward, frontal photographs and text-to-speech voice records of the participants were collected. CNN models and machine learning algorithms were employed to categorize the data into cooperative and non-cooperative groups. Nine different CNN models were employed to analyze images, while one CNN model and 13 machine learning models were utilized to analyze audio data. The accuracy, precision, recall, and F1-score values of these models were assessed. Xception (66%) and DenseNet121 (66%) were the two most effective CNN models in evaluating photographs. The model with the lowest success rate was ResNet101V2 (48.0%). The success rates of the other five models were similar. In the assessment of audio data, the most successful models were YAMNet, linear discriminant analysis, K-nearest neighbors, support vector machine, extra tree classifier, and stacking classifier (%58.7). The algorithm with the lowest success rate was the decision tree classifier (41.3%). Some of the CNN models trained with photographs were successful in predicting cooperation, but voice data were not as useful as photographs in predicting cooperation.

Low-level laser therapy (LLLT) has been widely implemented in the acceleration of orthodontic tooth movement (OTM). However, the impact of LLLT on the alveolar bone changes accompanying OTM has not been comprehensively addressed in a clinical trial. Hence, the objective of this investigation was to perform a three-dimensional (3D) assessment of the impact of LLLT on the changes in bone quality (bone density), and quantity (bone thickness and volume) during the canine retraction stage of orthodontic treatment. Twenty patients requiring maxillary first premolars’ extraction followed by canine retraction were recruited for this split-mouth study. Before the commencement of canine retraction, the maxillary arch in each of the enrolled subjects was randomly split into an “experimental” side, and a “control” side. In the experimental group, LLLT was performed on days 0, 3, 7, 14, and then every two weeks until the completion of the research duration (12 weeks). The employed diode laser was of 980 nanometers (nm) wavelength and a dosage of 8 joules per square centimeter (J/cm2), in a continuous mode. Canine distalization was accomplished using nickel-titanium closed-coil springs, with a force of 150 grams (g). Pre-retraction and post-retraction cone-beam computed tomography was performed to assess bone quality and quantity, in terms of alveolar bone density, thickness, and volume. A statistically significant reduction in bone density and volume was found following canine retraction (P < 0.05) with and without LLLT application. For the total bone thickness, a statistically significant decrease was observed at both the coronal and mid-root levels of the maxillary canine (P < 0.05), whereas an insignificant change was reported at the apical level (P > 0.05) in both the studied groups. Furthermore, insignificant differences were documented in all the measured outcomes between the experimental and the control groups (P > 0.05). With the employed parameters in the present study, LLLT does not positively influence the changes in neither bone quality (bone density) , nor bone quantity (bone thickness and volume) accompanying OTM. Moreover, a significant reduction in bone density, in bone thickness (coronal and mid-root levels), as well as in bone volume accompanies canine distalization in both groups.

The objective of this study was to delve into predictors of adherence in adult orthodontic patients as stated by orthodontists in Saudi Arabia. Ninety-one orthodontists from Saudi Arabia completed a questionnaire in relation to the importance and frequency of use of predictors of adherence. In this cross-sectional quantitative and exploratory study, orthodontists were requested to rate the predictors of adherence on a five-point Likert scale. The questionnaire in this study was categorized into four sections such as (1) evaluation – their opinion on the importance of predictor in the assessment of patient adherence, (2) application – scope of use of each predictor in the assessment of adherence in the routine practice, (3) open-ended questions to amass information about other apparent predictors of adherence, and (4) demographics. Mixed and variable responses were obtained in terms of the importance and extent of application of predictors in assessing patient adherence. The survey revealed the most important predictors for adherence that included patient’s adherence to appointments and their cooperation in handling dental appliances, and maintenance of oral hygiene. However, in actual practice, orthodontists were frequently implementing factors such as the patient to keep appointments, the patient is observed to be involved in treatment, and the patient is observed to be enthusiastic about treatment. Through the open-ended questions, multiple factors were reported that need to be explored further. However, the remaining factors reported for adherence portrayed varied patterns. Predictors of adherence were reported with varying extent of consistency among orthodontists in Saudi Arabia. However, adherence to appointment, co-operation in handling of appliances, and oral hygiene emerged as the most significant factors by the orthodontists for adherence in cases of adult patients.

The nasoalveolar molding (NAM) appliance has been the appliance of choice for pre-surgical orthopedics to improve nasal and lip morphology, and optimally align the alveolar segments before cheiloplasty. However, the appliance has some limitations, including its complexity and long clinical chair time for appliance adjustments. In this case report, we present a patient treated for a right complete cleft lip and palate using three types of Korat modification for NAM with a 5-year follow-up. This study demonstrated that the Korat-NAM improved the aforementioned issues and was suitable for patients at different stages before and after lip and palate repair.

Objectives: The first aim of this study was to investigate the correlation between chronological age, cervical vertebral maturation (CVM) stage, and midpalatal suture (MPS) maturation stage. The second aim was to assess the relationship between the prognosis for rapid maxillary expansion (RME) and age, CVM stage, and MPS maturation stage. Material and Methods: We divided 109 participants into three age groups: <15 years, 15–25 years, and >25 years. The participants had undergone both cone-beam computed tomography (CBCT) and lateral cephalometric X-ray examination. Their MPS maturation stage was classified as A to E and CVM stage as cervical stage 1 (CS1) to CS6, according to a previously proposed method. We used the weighted kappa coefficient to assess intra-examiner agreement and Spearman’s correlation coefficient, to evaluate the correlations of MPS maturation stage with age and CVM stage. Results: The weighted kappa coefficients were 0.849 and 0.923 for the identification of MPS maturation stage and CVM stage, respectively. There were significant, but weak correlations between MPS maturation stage and age ( r = 0.313, P = 0.001) and, CVM stage ( r = 0.287, P = 0.002). MPS stage C was the most prevalent across all age groups and all CVM stages. Conclusion: Chronological age and CVM stage may not accurately predict MPS maturation stage, especially in older patients. Further, the prognosis for RME may not be strongly related to either CVM or MPS maturation stage. We recommend using CBCT X-rays for individual MPS assessments before selecting the type of maxillary expansion treatment.
目的:本研究的第一个目的是探讨实足年龄、颈椎成熟(CVM)阶段和中腭缝合(MPS)成熟阶段之间的相关性。第二个目的是评估快速上颌扩张(RME)的预后与年龄、CVM分期和MPS成熟阶段的关系。材料和方法:我们将109名参与者分为三个年龄组:15岁、15 - 25岁和25岁。参与者接受了锥束计算机断层扫描(CBCT)和侧位头颅x线检查。根据先前提出的方法，将其MPS成熟阶段分为A至E期，CVM阶段分为宫颈1期(CS1)至CS6期。采用加权kappa系数和Spearman相关系数来评价MPS成熟阶段与年龄和CVM阶段的相关性。结果:MPS成熟期和CVM成熟期的加权kappa系数分别为0.849和0.923。MPS成熟阶段与年龄(r = 0.313, P = 0.001)、CVM阶段(r = 0.287, P = 0.002)存在显著相关性，但相关性较弱。MPS C期在所有年龄组和所有CVM分期中最为普遍。结论:年龄和CVM分期不能准确预测MPS成熟阶段，尤其是老年患者。此外，RME的预后可能与CVM或MPS成熟阶段无关。我们建议在选择上颌扩张治疗类型之前，使用CBCT x线进行个体MPS评估。
{"title":"Investigation of the correlation of midpalatal suture maturation stage with chronological age and cervical vertebral maturation stage","authors":"Chin-Chen Yang, Meng-Yen Chen, Jia-Kuang Liu, Chen-Jung Chang","doi":"10.25259/apos_86_2023","DOIUrl":"https://doi.org/10.25259/apos_86_2023","url":null,"abstract":"Objectives: The first aim of this study was to investigate the correlation between chronological age, cervical vertebral maturation (CVM) stage, and midpalatal suture (MPS) maturation stage. The second aim was to assess the relationship between the prognosis for rapid maxillary expansion (RME) and age, CVM stage, and MPS maturation stage. Material and Methods: We divided 109 participants into three age groups: <15 years, 15–25 years, and >25 years. The participants had undergone both cone-beam computed tomography (CBCT) and lateral cephalometric X-ray examination. Their MPS maturation stage was classified as A to E and CVM stage as cervical stage 1 (CS1) to CS6, according to a previously proposed method. We used the weighted kappa coefficient to assess intra-examiner agreement and Spearman’s correlation coefficient, to evaluate the correlations of MPS maturation stage with age and CVM stage. Results: The weighted kappa coefficients were 0.849 and 0.923 for the identification of MPS maturation stage and CVM stage, respectively. There were significant, but weak correlations between MPS maturation stage and age ( r = 0.313, P = 0.001) and, CVM stage ( r = 0.287, P = 0.002). MPS stage C was the most prevalent across all age groups and all CVM stages. Conclusion: Chronological age and CVM stage may not accurately predict MPS maturation stage, especially in older patients. Further, the prognosis for RME may not be strongly related to either CVM or MPS maturation stage. We recommend using CBCT X-rays for individual MPS assessments before selecting the type of maxillary expansion treatment.","PeriodicalId":42593,"journal":{"name":"APOS Trends in Orthodontics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135773681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This case report presents the multidisciplinary management of a patient with severe skeletal Class III malocclusion, anterior open bite, dentigerous cyst, and multiple restorations. The patient underwent orthodonticorthognathic treatment, autotransplantation, cyst removal, and esthetic rehabilitation with porcelain veneers. The presurgical orthodontic decompensation of the proclined upper incisors involved mini-screw-assisted entire upper arch distalization. The bimaxillary osteotomy included advancing the maxilla, mandibular setback, rotating the maxillomandibular complex clockwise, and moving the chin posteriorly. The role of multidisciplinary treatment is very important in orthognathic patients with compromised dentition. Autotransplantation could help patients avoid the need for prosthetic implants. Entire arch distalization could be a possible alternative to premolar extraction for presurgical orthodontic decompensation in cases of proclined incisors.
