Abstract: Background: In vitro studies conducted under simulated oral environment under estimated the force decay of elastomeric ligatures. There are only few invivo studies that are reported evaluating the force decay of elastomeric ligatures. Aim & 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 . Materials 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.). The mean force values and standard deviations for all the groups at each time period. The mean percentage of force decay between time periods for each study group was calculated. One way ANOVA followed by Post hoc Tukey HSD was performed for within the group and between group comparisons. Paired T test was done for pairwise comparisons. (P value≤ 0.05) Results: The mean force level recorded were high at the base line level with as received modules before inserting into the patients mouth for all the three study groups. The mean force level was 766.50 ± 3.659 gms, 650.50±2.759 gms and 594 .10 ± 4.630 gms for group I, II & III respectively in the as received condition. The percentage of force decay was 32.94 % at 24 hrs and 69.85% at 7 days and 79.31% at 21 days for Group I. A force decay of 31.36%, 70.76% and 79.83% from the base line value was noted in group II at the same time intervals. In Group III The force decay rate at 24 hrs, 7 days and 21 days were 33.29%, 66.10% and 77.12% respectively. One way ANOVA for within group and between group comparison showed a significant difference between the force levels recorded at different time intervals within and between all the three study groups. Post Hoc Tukey HSD revealed a significant difference between the three groups at all the time intervals tested except at 7 days and 21 days where the force levels exerted by the group II and Group III samples were not significantly different.

Facial characteristics are affected by facial proportions, growth pattern, facial heights and smile of the patients. Long face syndrome usually presents with an increased lower anterior and total anterior facial height, a gummy smile, a hyperdivergent growth pattern and decreased facial height. However, there are many variations in the posterior facial height and the growth pattern. There can be patients having an increased anterior facial height with increased or average posterior facial height, or an average and reduced mandibular plane angle. This paper aimed at reviewing the various characteristic facial variants of an increased anterior facial height. This article reviews three such variants of an increased anterior facial height. It particularly highlights the variant with increased anterior and posterior facial height and the modification in the treatment of such cases. The most common treatment option for the normally occurring variant of hyperdivergent growth pattern with a reduced posterior facial height is surgical superior impaction.

Aim: The aim of this study was to do a 3-dimensional analysis of the upper and lower dental arch forms and compare the same between male and female South Indian subjects who were not previously treated with fixed orthodontic appliances.Materials and Methods: The sample consisted of 3D scans of dental casts from 50 untreated patients(25 males and 25 females) in permanent dentition. An assessment of the arch form was performed using angular and linear values on scans using a software(MEDIT).The data was tabulated and statistically analyzed using SPSS software and Student’s t test(2- tailed) was used to determine statistical significance of differences in measurements between the two groups.Results: In male subjects the intercanine, intermolar, interpremolar diameters and arch depth were significantly greater than females and there was a statistically significant difference (p value=<0.05).Conclusion: Ovoid arch form is commonly seen in both South Indian males and females followed by broader arch forms in males and tapered arch forms in females. South Indian males have wider arches when compared to females.

This study aimed to report the treatment steps in a 26-year male patient, presented with a class II div 1 incisor relationship on a class II skeletal base with increased vertical proportions. The case was complicated by missing lower second premolars and retained lower second deciduous molars. Severe crowding was evident in the lower arch with mild crowding in the upper arch. The overbite and the overjet were increased. Scissor bite was evident in the left buccal segment. Treatment involved extraction of upper first premolars and lower second deciduous molars, utilizing moderate anchorage using a preadjusted edgewise fixed appliance (0.022’’ X 0.028”) with Roth prescription. Treatment duration was 20 months in total. The envelope of discrepancy specifies strict rules when camouflaging class II cases. The ability to retract incisors and the use of class II mechanics are within limited range to avoid damage to the periodontium. The current case report showed that the ability of the clinician to retract incisors using TADs could be carried out with high rate of success and safety.

There is an increasing trend in adults seeking orthodontic treatment. Visibility of braces and duration of treatment are factors detrimental to patients choice of having orthodontic treatment as well as their satisfaction with the outcome. Adult orthodontics is unique both in the treatment goals as well as tissue response. Realistic goals with adjuvant procedures and short duration of treatment are preferred. We present two cases of “Limited outcome orthodontics” in adult patients with localized malalignment, successfully managed within a very short duration of 5 months.

Aim: To evaluate and compare perceived pain and discomfort levels experienced by subjects treated with tooth-borne (Hyrax) and bone-borne (MARPE) Maxillary expansion appliances. Materials and Methods: Ten subjects (7 boys and 3 girls) with a mean age of 15.8(+/- 2.8) years were randomized into two groups. Group A received a MARPE appliance anchored using mini-implants in the anterior palate and group B received a conventional Hyrax appliance. A self-assessment questionnaire on pain intensity, discomfort and analgesic consumption was given to subjects on the review visit and responses were collected. Descriptive statistics and Mann-Whitney U test was done to compare the mean of pain and discomfort levels between the two groups. Results: All 10 subjects answered the questionnaire. More pain was experienced in the posterior teeth region by subjects treated with MARPE (p<0.05). No significant intergroup difference in pain levels experienced in the anterior region, palatal vault and the head region and analgesic consumption was noted. (p>0.05) Conclusions: Although both Hyrax and MARPE were generally well tolerated there was a significantly higher pain experience in posterior teeth region for subjects treated with MARPE.

Background: Dental care facilities generate a high amount of Biomedical Waste (BMW) like sharps such as surgical needles, blades, wires, brackets, extracted teeth, human tissues, discarded or expired medicines and dental materials, highly contaminated with blood and saliva. Segregation and collection should be done in separate colour coded bags or containers; according to Biomedical Waste Rules, 2016 the Ministry of Environment and Forest in India. Poor management of wastes leads to high risk to public, patients and professionals and also contributes to environmental degradation. Aim: To assess the knowledge and awareness on management of biomedical waste management among orthodontists and practicing general dentists. Materials and methods: A cross sectional study was conducted through Google form (electronic based survey) among general practising dentists; survey consisted of 18 closed ended questions. The data collected were tabulated in Microsoft Excel and exported to SPSS, descriptive statistics and Chi-Square test was performed (p < 0.05 was considered statistically significant). Results: 83.8% practising dentists follow the biomedical waste disposal policy in their hospital or clinic, among which 91% use protective barriers (e.g. gloves, masks) during handling of biomedical waste. 63.1% disposed human anatomical waste and blood contaminated waste properly where only 55.9% disposed extracted teeth and human tissue in yellow bags. Significant association was found between management of incinerated ash and qualification among orthodontists ( p=0.019) and with experience of less than 1 year had proper knowledge; (p=0.021). Disposal of plaster of Paris was properly managed among general practioners (p=0.039). Management of sharps was done properly using needle destroyers among general dentists and orthodontists (p=0.041). Conclusion: Safe and effective management of biomedical waste is a legal necessity but also a social responsibility of dentists, according to this present survey 7 – 9.2 % of the dentists are not effectively following the biomedical waste management.

Aim: The aim of the current study is to compare the healing following gingivectomy procedures using the Diode system and Er:Cr:YSGG lasers in patients undergoing fixed orthodontic treatment. Methodology: The study is a single center randomized controlled clinical study with a sample size of 40 patients who underwent gingivectomy using lasers. The patients were divided into two groups randomly (Group A= 20 and Group B= 20). Group A patients had undergone gingivectomy using diode laser (BIOLASE EPIC X,940 nm) and Group B patients had undergone gingivectomy using Er:Cr:YSGG laser (Waterlase,2780nm). The patients were followed at day3, day 7 and day 14. The wound healing was assessed post laser application using a healing index by Landry et al at different time intervals. Data were entered in Microsoft Excel spreadsheet and analyzed using SPSS software (IBM SPSS Statistics, Version 20.0, Armonk, NY: IBM Corp.). Independent t test was used to compare the mean healing index score between the groups. Repeated measures ANOVA and Post hoc Bonferroni test was used for comparison of mean healing index scores of Group A and B at different time periods Result: When comparing the healing index at day 3 between the groups, there was no significant difference between the diode laser and erbium laser group (P = 0.24). Similarly at day 7 and at day 14, there were no significant differences between the groups (P= 0.20), (P= 0.18) at day 7 and day 14 respectively. When comparing the healing index score of gingivectomy with diode laser between different time intervals, there was a statistically significant healing was seen at day 14 (P = 0.001). The healing at day 14 was significantly better than day 3 and day 7 in the erbium laser group (P =0.001). Conclusion: Within study limits it is concluded that Er:Cr:YSGG lasers have better healing compared to diode lasers following laser assisted gingivectomy although the results are not statistically significant. Thus, the use of laser is an effective treatment approach in the management of orthodontic associate gingival enlargement.
目的:本研究的目的是比较二极管系统和Er:Cr:YSGG激光在固定正畸治疗患者牙龈切除术后的愈合情况。方法:该研究是一项单中心随机对照临床研究，样本量为40例接受激光牙龈切除术的患者。将患者随机分为两组，A组20例，B组20例。A组患者行二极管激光(BIOLASE EPIC X,940 nm)牙龈切除术，B组患者行Er:Cr:YSGG激光(Waterlase,2780nm)牙龈切除术。随访时间分别为第3天、第7天和第14天。Landry等人在不同时间间隔使用愈合指数评估激光应用后的伤口愈合情况。数据在Microsoft Excel电子表格中输入，并使用SPSS软件(IBM SPSS Statistics, Version 20.0, Armonk, NY: IBM Corp.)进行分析。采用独立t检验比较各组间愈合指数平均评分。采用重复测量方差分析和Post hoc Bonferroni检验比较A组和B组不同时间段的愈合指数平均值。结果:组间比较第3天的愈合指数，二极管激光组与铒激光组比较，差异无统计学意义(P = 0.24)。在第7天和第14天，各组间差异无统计学意义(P= 0.20)，第7天和第14天差异无统计学意义(P= 0.18)。比较不同时间间隔的二极管激光牙龈切除术的愈合指数评分，第14天的愈合有统计学意义(P = 0.001)。第14天的愈合明显优于第3天和第7天(P =0.001)。结论:在研究范围内，Er:Cr:YSGG激光比二极管激光在激光辅助牙龈切除术后具有更好的愈合效果，尽管结果没有统计学意义。因此，激光是治疗正畸伴发牙龈肿大的有效方法。

The patients were divided into two groups randomly (Group A= 20 and Group B= 20). Group A patients had undergone gingivectomy using diode laser (BIOLASE EPIC X,940 nm) and Group B patients had undergone gingivectomy using Er:Cr:YSGG laser (Waterlase,2780nm). The patients were followed at day3, day 7 and day 14. The wound healing was assessed post laser application using a healing index by Landry et al at different time intervals. Data were entered in Microsoft Excel spreadsheet and analyzed using SPSS software (IBM SPSS Statistics, Version 20.0, Armonk, NY: IBM Corp.). Independent t test was used to compare the mean healing index score between the groups. Repeated measures ANOVA and Post hoc Bonferroni test was used for comparison of mean healing index scores of Group A and B at different time periods \u0000Result: \u0000When comparing the healing index at day 3 between the groups, there was no significant difference between the diode laser and erbium laser group (P = 0.24). Similarly at day 7 and at day 14, there were no significant differences between the groups (P= 0.20), (P= 0.18) at day 7 and day 14 respectively. When comparing the healing index score of gingivectomy with diode laser between different time intervals, there was a statistically significant healing was seen at day 14 (P = 0.001). The healing at day 14 was significantly better than day 3 and day 7 in the erbium laser group (P =0.001). \u0000Conclusion: \u0000Within study limits it is concluded that Er:Cr:YSGG lasers have better healing compared to diode lasers following laser assisted gingivectomy although the results are not statistically significant. Thus, the use of laser is an effective treatment approach in the management of orthodontic associate gingival enlargement.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44825542","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}

Aim and Objectives The aim of this review is to systematically evaluate and assess the available evidence on arch dimensional changes in the mandible following expansion using Schwarz Appliance in growing patients. Materials and Methods The protocol for the review was registered with the PROSPERO database. A systematic search was done on the following scientific databases PubMed, Cochrane Central, LILACS and Google Scholar to identify articles of relevance published until April 2021. Articles that satisfied the inclusion criteria were included in the review. The review was performed based on the PRISMA guidelines. MINORS tool was used to evaluate the Risk of Bias and quality of evidence of the included studies. Results 243 trials were identified after implementing the search strategy. After eliminating duplicates 196 trials remained. After screening the titles and abstracts for the eligibility criteria, 190 trials were eliminated from further review. Full text was sought for the remaining six articles and one study was eliminated after review of the full text. Four the included studies showed low Risk of Bias in their methodologies and one study showed a low risk of Bias in its methodology. Qualitative analysis was performed on the remaining five trials. The studies significant increase in the Intermolar, intercanine, interpremolar and arch perimeter and also observed significant up righting of the permanent mandibular first molar. Conclusion Arch dimensional changes in the mandible of growing patients after expansion using Schwarz Appliance are dento-alveolar in nature. No skeletal Expansion is seen.

Orthodontic treatment can be part of a dental interdisciplinary treatment as a way to help other specialists in the team achieve efficient treatment results when dealing with complex cases. The team members must have basic and sufficient knowledge related to other disciplines if they are to have common ground for fruitful discussion of treatment options and possible solutions that will provide optimum esthetics and function, especially for adult patients. This article discusses important factors related to endodontics, periodontics, and restorative/prosthodontics and their interactions with orthodontics.
