To test the alternate hypothesis that salivary alkaline phosphatase is a reliable indicator of skeletal maturity in comparison with other methods of assessment of skeletal maturation. Total 112 subjects were selected out of 150 subjects on the basis of inclusion and exclusion criteria, for participation in the study. For each subject, personal details including chronological age was noted. Height and weight measurements were done for calculation of body mass index (BMI). Further, Lateral Cephalogram and Orthopantomogram were obtained for assessment of cervical vertebrae maturation stages and Demirjian index. Then, an unstimulated salivary sample was collected for evaluation of alkaline phosphatase activity by colorimetric method. The data obtained was analyzed using SPSS software. The results of the present study showed that the highest correlation for skeletal maturation assessment was found with alkaline phosphatase activity. The hypothesis is accepted.

Appropriate biomechanical use of temporary anchorage devices (TADS) will enable the clinician to avoid undesirable tooth movements. The following are two cases in which simple and efficient biomechanics have been performed with the use of TADS for the correction of incisor inclination and deep overbite.

During the decades-long period of cephalometric dominance, the \"aesthetic\" of the face was predominantly used to describe the profile as observed on a lateral cephalogram However, the paradigm has now shifted to soft tissue-based diagnosis and treatment planning. This creates the need for soft tissue-based analysis especially on photographs considering its evaluation of myriad populations. To evaluate the skeletal cephalometric parameters and photograph-based soft tissue parameters in the Malwa population. The study was conducted using 50 lateral cephalometric radiographs and 50 profile photographs. Data were analyzed for probability distribution using the Shapiro-Wilk test. Descriptive statistics were performed and data were presented as median and inter-quartile range. Correlation between the variables was assessed using Spearman’s correlation coefficient. P value < .05 was considered statistically significant. Our reported values of both photographic and lateral cephalogram parameters are different not only from the international population, but also different values are observed from the not only Indian population, but also from various subsets of the Indian population. Therefore, the average value of lateral profile photographic parameters as well as cephalometric parameters in my study can be used as floating norms for the Malwa population.","PeriodicalId":497876,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971971","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}

In contrast to fixed appliance treatments (FAT), the relationship between external apical root resorption (ERR) and clear aligners is still unknown. The objective of this systematic review was to evaluate the frequency and severity of root resorption in clear aligner orthodontic treatment, compare it to fixed multi-bracket appliances, and determine the factors that contribute to this phenomenon. The review was conducted without regard to linguistic constraints, using PRISMA criteria and examining studies from 2000 to 2023. MEDLINE/PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were among the databases that were searched. MeSH words about root resorption, aligners, and orthodontics were utilized. Cohort studies, case-control studies, randomized clinical trials, and comparative clinical studies assessing root resorption during clear aligner orthodontic therapy. Out of the 116 studies that were first found, 11 studies were included in the final analysis. While several trials revealed equal results or no significant differences, six reported decreased incidence and severity of ERR in clear aligner therapies (CAT) compared to FAT. A meta-analysis revealed that CAT had less severe ERRs than FAT. In both treatments, ERR frequently affected the maxillary lateral incisors. Potential significant factors included the mechanical distinctions between CAT and FAT, length of therapy, tooth movement velocity, degree of malocclusion, and extraction instances.The review indicates that there may be differences in the frequency and intensity of ERR between CAT and FAT. In multiple investigations, CAT demonstrated reduced ERR severity, although it did not completely eradicate its recurrence. Mechanical characteristics, length of therapy, degree of malocclusion, and number of extraction instances were factors affecting ERR. The included studies' quality assessment indicated a moderate to substantial risk of bias, highlighting the need for more thorough research using reliable measuring techniques, especially when utilizing CBCT imaging.","PeriodicalId":497876,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140974732","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}

In individuals with Class II malocclusions, there is an anteroposterior discrepancy between the maxillary and mandibular dentitions, which is usually accompanied by a skeletal discrepancy. In such malocclusions, a functional appliance (myofunctional or fixed functional) is chosen as a treatment method depending on the severity and need of the particular case. This systematic review aims to evaluate the dental-alveolar, skeletal and soft tissue changes with the use of Advansync™ (A Class II corrector/ fixed functional appliance) in the treatment of Class II malocclusion. A literature search was done on Pubmed, EbscoHost , Google Scholar, Science Direct. This was conducted by two reviewers independently and any conflicts in results were managed through discussion. A Risk of Bias was done for the final articles included in the study. A total of 3,099 records were identified while searching through the database based on Mesh terms and search strategies. Based on the inclusion and exclusion criteria’s the total articles which were eligible for the systematic review were six. As the study was specific in terms of age and gender there was a high risk of selection bias but low risk of reporting bias.Out of the 6 studies, 5 had a low risk of bias and based on their cumulative findings, the effectiveness of Advansync is similar to those of other Class II correctors. The advantage of Advansync over other correctors is that the appliance saves treatment time and can be incorporated from the second month of treatment thereby shortening the duration of treatment.Fixed Class II correctors are used widely in Orthodontics. The selection of the appropriate appliance for the patient is the need of the hour. Thus, this systematic review gives us an insight on the use of Advansync in Class II correction.","PeriodicalId":497876,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"133 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140977073","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 study aimed to evaluate the correlation of mandibular ramus to the mandibular base ratio with mandibular incisor proclination in a mixed Indian population.A total of 100 cephalograms were selected from the archives of the department of orthodontics fulfilling inclusion and exclusion criteria.The mean age of cases studied was 17.09 ± 2.61 years, with an age range of 13–26 years. The sample comprised 47 males and 53 females. The results of this study showed that the higher incisor mandibular plane angle (IMPA) has statistically and clinically significant association with a higher ramus to mandibular base ratio in both male and female groups. The unit increase in IMPA is significantly associated with a 0.004 unit increase in the ratio of ramus to mandibular base. This study concludes that the IMPA and ratio of ramus to mandibular base are the closest counterparts of each other and explains the variations in the IMPA even in the population group with similar skeletal characteristics. These two components interacts with each other to give a balanced occlusion and function.","PeriodicalId":497876,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"56 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140974987","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}
