The Skeletal Class II malocclusion is one such phenotype, which is a polygenic, complex disorder. The identification of epigenetic regulators would aid in understanding the complex relationship between the epigenetic marks and the phenotype. Also, these epigenetic marks can be considered for developing diagnostic leads upon validation for a specific disorder. Materials and methods: The present study follows an observational study design, which was performed using computational tools. The preliminary data about the genes associated with the Skeletal class II malocclusion was derived from DisGeNet, followed by identification of the protein-protein interaction networks. The microRNA targets were then identified using miRDB and the unique microRNA population common to all the five genes were further curated using the Venn plot. Results: The DisGeNet database provided information on the genes that were associated with skeletal Class II malocclusion. The five genes identified were ACTN3, GH1, HDAC4, HMGA2 and KAT6B. One microRNA, hsa-miR-892c-5p was unique to ACTN3, HDAC4 and HMGA2. The hsa-miR-3925-5p and hsa-miR-590-3p were found to be common to the genes ACTN3, HDAC4 and GH1 + HMGA2 respectively. Discussion: The identification of microRNAs targeting candidate genes could aid in defining the role of these microRNAs in establishing the phenotype. The future scope of this study lies in curating microRNAs that are common to class II malocclusion related candidate genes.

Resin based adhesives are conventionally used but have drawbacks like white spot lesions and technique sensitivity. To overcome these problems, Resin modified glass ionomer cements (RMGIC) were introduced to utilise the fluoride releasing characteristic of GIC. Aim: To compare and evaluate bond failure rate and type of bond failure between brackets bonded with RMGIC and composite. Materials and methods: 25 patients undergoing orthodontic treatment were included and evaluated for 6 months. Bonding was done with RMGIC and composite. Patients were recalled every month and bond failure rate and type of bond failure was evaluated. Results: A total of 526 teeth were bonded out of which 263 were bonded with RMGIC and 263 with composite. Statistical analysis was done with Chi-square test (p>0.05). Maximum debonding was seen in RMGIC group (6.46%) compared to composite (3.42%). Maximum debonding was seen in 1st molars bonded with RMGIC (35.3%). Majority bond failure type observed was Adhesive enamel failure in brackets bonded with RMGIC. Conclusion: From the study, it can be concluded that bond failure was commonly seen in RMGIC group in comparison with composite group. Adhesive enamel failure was the most commonly seen bracket failure type. RMGIC had majority bracket failure but within acceptable range and hence can be used as a substitute adhesive for bonding.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135302378","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}

A multidisciplinary approach is particularly important for the successful treatment of chronic TMD cases. Management of TMD involves the work of dentists from various specialities. It is multifactorial in nature and requires proper examination and treatment planning. Thus, the primary purpose of this study is to find out the awareness of TMDs among postgraduate students. MATERIALS AND METHODOLOGY: The present study was retrospective in nature. A questionnaire involving TMDs was sent to all postgraduates involved in patient treatment through google forms. All participants were asked to anonymously answer the structured questionnaire containing multiple-choice and open-text questions in google forms. The questionnaire was specially developed for students and was organized into three sections. RESULTS: 204 participants responded and returned the completed questionnaires. Results showed that 98 % of the respondent’s occlusal disturbance causes TMD and TMJ problems are associated with malocclusion. The majority of the participants were aware of the aetiology and diagnosis but only 53% of them were aware of the treatment protocols. CONCLUSION: The causes and diagnosis domains of the questionnaire yielded a high degree of agreement while the treatment modalities were not known. Most of them were not aware of the treatment modalities reason being a lack of knowledge during the course of their undergraduate and postgraduate study.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135720670","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}

Since the anterior cranial base shows little growth after the age of 7, it is regarded as a stable reference for cephalometric analysis. Objective: The aim of this study was to predict skeletal malocclusion by correlating the length of the cranial base and the volume of the sphenoid sinus in different sagittal skeletal patterns.Materials and methodology: In this study, a total of 30 cone beam computed tomography (CBCT) scans of patients, aged between 18 and 35 years who underwent orthodontic and orthognathic treatment were evaluated. DICOM files from the CBCT scans were imported and viewed using Dolphin imaging software. Skeletal malocclusion was evaluated using a lateral cephalogram obtained from the CBCT. Volumetric analysis of the sphenoid sinus and length of the cranial base was evaluated with the help of the Dolphin imaging software. A normality test was done to decide the statistical method for data analysis. A one-way ANOVA with Tukey’s post hoc test was done to compare the three groups. Results: There was a correlation noted between the volume of the sphenoid sinus in skeletal class II malocclusion but no correlation was noted in the length of the cranial base.

With the increase in the number of adult patients seeking fixed orthodontic treatment, there is a need to find a more reliable procedure to bond the artificial crown surface. Successful orthodontic treatment requires sufficiently high and durable bond between buccal tubes and ceramic/zirconia surfaces. There is a need for a bonding agent which can provide maximum bond strength to all surfaces. This study aimed to assess and compare the shear bond strength and adhesive remnants of orthodontic buccal tubes to natural teeth, ceramic crowns and zirconia crowns using two different bonding systems. METHODS: In this in vitro study, 60 extracted human molar teeth were randomly assigned to three groups (n=20) and then divided into two subgroups(n=10). Bonding of buccal tubes to enamel, ceramic and zirconia surfaces was done using Assure plus universal bonding resin and Enhance LC. The shear bond strength of buccal tubes to the enamel, ceramic and zirconia surfaces were determined by universal testing machine. The SBSs and ARI scores were statistically analysed with and Kruskal Wallis test. RESULTS: The mean shear bond strength of buccal tubes to enamel, ceramic and zirconia surfaces bonded with Assure plus and Enhance LC was highest for enamel followed by zirconia surfaces respectively. Non-parametric Kruskal-Walli’s test found significant differences regarding the shear bond strength and adhesive remnant index (ARI). CONCLUSION: Bonding of buccal tubes to enamel, zirconia, and ceramic surfaces with Assure universal bonding resin and Enhance LC provided adequate bond strength. Thus, it may be used for bonding of orthodontic buccal tubes to the artificial crown surfaces in the clinical setting.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135260657","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}
