Orthodontic treatment is no longer reserved for only healthy patients. With better management of serious medical problems, increased quality of life expectations, and greater ambulation, medically compromised individuals are now regular visitors to orthodontic practices. While orthodontic treatment has been historically considered to be completely noninvasive, specific orthodontic procedures may place some patients at risk for serious sequelae. Among the most common of these conditions are those associated with cardiovascular disease, bleeding disorder, respiratory disorder, neurological disorder, renal disease, musculoskeletal system, endocrine disorder, liver disease, allergies, and drug side effects. Aggressive risk assessment is the key factor in the identification and prevention of medically associated problems. Assessment and management of patients at risk for endocarditis, bleeding, and asthmatic attacks are discussed. The orthodontic treatment of patients with medical disorders is becoming an increasing aspect of modern-day practice. The influences of various systemic diseases on orthodontic treatment have been discussed and various recommendations to overcome the potential problems have been highlighted in this article.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48298713","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}

Materials and Methods: The sample consisted of fifty adult patients with a mean age of 24.5 years, with Class II malocclusion, and the patients were divided into two groups. In Group A, 0.022” McLaughlin, Bennett, and Trevisi Bracket System (MBT) was used in 25 patients as fixed orthodontic treatment and 0.016” nickel-titanium (Ni-Ti) wire was placed for initial alignment, whereas in Group B, a total of fifty mini-screws were placed in 25 patients, one mini-screw on each side in the maxilla between the 2nd premolar and the 1st molar. The patients answered a questionnaire to assess their opinions on treatment. Results: The data of description of pain experienced in 24 h, 2nd day, and 7th day in Group A and Group B are enumerated. In Group A, the pain experienced in 24 h, 2nd day, and 7th day was 49.72 (36.22), 37.17 (35.32), and 17.34 (14.45) and in Group B, it was 24.72 (15.65), 13.32 (14.34), and 12.45 (11.60), respectively. The questionnaire set was completed for functional aspect evaluation. The descriptive data of visual analog scale were presented. During this study, patient had difficulty in eating, food sticking around implant, and interference during tooth brushing was moderate, but there was no any anaesthetic appearance and disturbance in chewing ability was noted. Statistical Analysis: The nonparametric Kruskal–Wallis and Mann–Whitney tests were performed to evaluate the differences between the groups for pain. The Chi-square test was used to determine differences between the procedures. Differences at P < 0.01 were considered statistically significant. Statistical software, namely, SAS 9.0 (SAS Institute Inc., Cary, NC, USA), the Statistical Package for the Social Sciences (SPSS), version 15.0 (SPSS Inc., Chicago, IL, USA), and Systat 11.0 (Systat Software Inc., Chicago, IL, USA), were used for the analysis of data.

Materials and Methods: Radiographs involving SP (n = 158; 77 female and 81 male, age with a mean value of 12.84 ± 1.94 years) were evaluated retrospectively. Class I group included 52 subjects (0 ≤ ANB ≤4), Class II group included 57 subjects (ANB>4), and Class III group included 49 subjects (ANB <0). The length of the SP was measured in Photoshop CS5 software (Adobe Systems Inc., San Jose, CA, USA). Skeletal maturation stages were determined by the evaluation of hand-wrist radiographs and lateral cephalometric radiographs. The data were analyzed using Student's t-test and one-way ANOVA. Results: Statistically significant difference in the length of the SP was found between Class I and Class II group (P ≤≤≤05). The mean length of the SP was 30.68 ± 9.69 mm in Class I group and 34.63 ± 5.87 mm in Class II group. No statistically significant difference was found in between skeletal maturation stages of the groups neither in the bilateral length of the SP between genders. Conclusion: The risk of Eagle syndrome in skeletal Class II malocclusion might be higher. In addition, when a patient is referred with pain in the temporomandibular area with skeletal Class II anomaly, SP elongation should be considered besides the joint problems.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47960301","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}

Materials and Methods: Thirty pretreatment lateral cephalograms obtained from the same digital cephalostat were analyzed. Tracings were done using CephNinja for iPhone (Cyncronus) and manually by the hand on acetate sheets. Cephalometric landmarks and angular and linear measurements were recorded. All tracings were performed by the same investigator. Statistical Analysis: To evaluate reproducibility, for each cephalometric measurement, the agreement between the value derived from CephNinja, and that measured manually was assessed with the intraclass correlation coefficient (ICC). Agreement was rated as low for an ICC <0.75 and an ICC >0.75 was considered indicative of good agreement. Furthermore, differences in measurements between those derived from CephNinja application and manual tracing were statistically evaluated (P < 0.05). Results: All the measurements had ICC >0.75, indicating high agreement among both the tracing methods. Differences in measurements between CephNinja and hand tracing were not statistically significant for any of the cephalometric parameters.

Materials and Methods: A total of sixty individuals (thirty males and thirty females) between 18 and 27 years of age were selected. The pretreatment lateral cephalograms of the samples selected (n = 60) for the study were divided into two groups, Group I and Group II, after which posteroanterior cephalograms were taken for the measurement of asymmetry. All the cephalometric parameters were defined as quantitative variables. The mean and standard deviation (SD) for each measurement was calculated. The results were presented in frequencies, percentages for qualitative data, and mean ± SD for quantitative data. Paired t-test was used to test the significance (P = 0.05 or less) in the difference between the right and left sides of the face. Chi-squared test was used to check the significance of difference in proportions. All the analyses were carried out on MS-Excel and SPSS 16.0 version (Chicago, Inc., Illinois, USA). Results: In Group II, the parameters for mandibular morphology and volumetric comparison and the mean of all parameters taken were statistically insignificant, but the mean for condylion-antegonial notch was greater for the right side, and the difference between the left and right sides was statistically significant (P = 0.019). When comparing the cephalometric parameters between the left and right sides in Group I and Group II, none of the mean values were proved to be statistically significant, but the right side parameters revealed to be greater than the left side of the measured parameters. Conclusion: All participants showed mild skeletal asymmetry on posteroanterior cephalograms, which was not statistically significant. In Group II, the relative mean of condylar asymmetry was statistically significant, which proves the presence of some amount of condylar asymmetry in this group. The other cephalometric parameters measured in our study showed that the value of the same was greater for the right side than the left side.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44967461","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}
