Millions undergraduates are active users of WhatsApp platform and this can be used for learning and evaluation.\u0000Objectives: The study's goals and include using WhatsApp to reinforce pre-clinical wire bending exercises among undergraduate dental students and assessing the effectiveness and acceptability of this platform among them.\u0000Materials and Methods: This prospective study was conducted over a nine-month period and included 79 final-year BDS students from Mansarovar Dental College in Bhopal. The research was divided into three three-month sessions. An examination of similar questions of 10 MCQ and 10 Likert questions was conducted at the beginning and end of each session. A WhatsApp group called \"Let's Learn Wire Bending\" was formed, and digital images of wire bending exercises with step-by-step instructions and clinical benefits were posted. WhatsApp discussions about each appliance were held for three months, and at the end of the third month, an offline examination was held using the first question paper set, and student progress was evaluated.\u0000Statistical analysis: Shapiro-Wilk’s test was applied for evaluating normality of samples distribution, and in non-parametric data obtained from the Likert’s score was converted into mid-point data analysis, and comparison between groups. Mann-Whitney U test was applied to assess acceptability.\u0000Results: There was a statistically significant difference between before-session test results and after-session test results with a p-value less than 0.001. Likert feedback questionnaire revealed that students enjoyed this method of teaching.\u0000Conclusions: The present study concluded that teaching pre-clinical wire bending exercises through WhatsApp application reinforces the traditional method of pre-clinical demonstration. \u0000","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42452275","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}

The present case series discusses a hybrid type of fixed functional appliance, i.e. Twin Force Bite Corrector appliance in three cases: A 15‑year‑old female patient with Class II malocclusion due to mandibular retrognathism, a 14‑year‑old male patient with Class II malocclusion due to mandibular retrognathism, and a 14‑year‑old female patient with Class II malocclusion due to mandibular retrognathism. The effects produced by this appliance are similar to the conventional fixed functional appliances such as Forsus, Herbst, and also it has a distinct advantage of quick chair-side fabrication and simple design.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44023411","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}

There are only few invivo studies that are reported evaluating the force decay of elastomeric ligatures.  \u0000Aim & Objectives:  The aim of this in-vivo study was to evaluate the force decay of three different clear elastomeric ligature modules stretched over the lower incisor brackets intra orally over three different time periods at 24 hrs, 7 days and 21 days by comparing it with the force levels evaluated at as received conditions . \u0000Materials and methods: Ten patients undergoing fixed orthodontic treatment with  Roth Prescription, 0.022\" slot preadjusted edgewise stainless steel brackets   with aligning and levelling completed and   0.019\" x 0.025\" SS arch wire placed passively in the lower arch were included in the study. The three types of elastomeric ligature modules formed the three study groups [Group I: Molded“O” (Ormco, USA),Group II: Alastik (3M Unitek, USA)&Group III: Uni-stick (American orthodontics, USA)] Each group was assigned with a specific lower incisor in each patient and the respective modules were used in the teeth during the study period. The force levels required to stretch the modules to a predetermined length of 4.1mm were evaluated at 4 different time intervals at 0 hour (as received), 24, 7 days, and 21 days after intra-oral use using a universal testing machine (Instron model 1112, Instron Corp.).
