Objective: To assess the efficacy of therapeutic ear plugs in the treatment of myogenous TMD compared to stabilization splints. Materials and Methods: 60 patients suffering from myogenous TMD according to DC/TMD criteria where divided into 2 group, stabilization splint group, and a group treated with therapeutic ear plugs. Pain was evaluated using visual analog scale VAS, and mouth opening was evaluated using a mouth opening index OI, after 1 and 3 months. Results: Pain was reduced significantly in the ear plug group, dropping from 7.18 to 3.82 after 1 month and to 2.41 after 3 months. For the splint group there was significant drop in pain after 3 months where it decreased from 7.34 to 2.63, while it showed a nonsignificant decrease after 1 month (6.16). OI showed significant improvement in mouth opening in the ear plug group decreasing from 10.34 to 6.14 after 1 month and to 5.13 after 3 months. In the splint group the OI improved significantly from 11.06 to 4.87 after 3 months, while the improvement wasn’t significant after 1 month (9.85). Conclusions: Therapeutic ear plugs are a discrete, small, and effective alternative to stabilization splint in the treatment of myogenous TMD, and its full-time wear advantage over the splint makes its

Aim: The aim of this randomized controlled trial (RCT) was to determine whether gargling with green tea was effective in reducing pain after orthodontic elastomeric separators placement. Materials and methods: A total of 50 patients with an age range between 13 and 17 years were recruited and randomly allocated in a ratio of 1:1 to the green tea mouthwash group (GTG) and the control group (CG). Patients in GTG were instructed to gargle with green tea mouthwash after two hours from separators placement and every eight hours afterwards for a week, while participants of CG were asked not to rinse their mouths. The patients in the two groups were instructed not to use any kind of local or systemic analgesics throughout the duration of the study. A 10-cm horizontal visual analog scale (VAS) was used to assess the pain at two hours, six hours, bedtime, 24 hours, and then daily after separators placement for seven days. Results: One patient in each group was lost to follow up and one patient in the CG was excluded because of using analgesics; therefore, 23 patients in the CG and 24 patients in the GTG were analyzed. Although the pain scores were lower at all time points in GTG group, the difference between the two groups was statistically non-significant. Conclusion: Gargling with green tea mouthwash three times daily does not seem to significantly reduce the pain after orthodontic elastomeric separators placement as compared to controls.

Objective: To determine changes in the oropharyngeal airway in Class III patients treated by bimaxillary surgery, and to find possible correlation between oropharyngeal airway changes and the skeletal movements. Materials and Methods: Lateral cephalograms of 30 class III patients (16 females, 14 males, age: 18-25 years old) treated with maxillary advancement and mandibular set-back were evaluated presurgery (T1), post-surgery (T2) and 12 months post-surgery (T3). The anteroposterior oropharyngeal airway and skeletal changes of the maxilla and mandible were measured. ANOVA was performed to determine significant differences between the different time points. Pearson correlation coefficient was used to assess correlations between the changes in oropharyngeal airway and the amount of jaws movements. Results: Parameters indicating anteroposterior maxillary position showed significant increase from T1 to T2 and from T1 to T3. Parameters indicating antero-posterior mandibular position showed significant decrease from T1 to T2 and from T1 to T3. Anteroposterior oropharyngeal airway space showed significant increase from T1 to T2 and from T1 to T3. All measured variables in the study showed insignificant differences between T2 and T3 indicating insignificant relapse of the surgically induced changes. Pearson's correlation analysis showed a statistically significant moderate positive correlation between the oropharyngeal airway increase and the amount of the maxillary advancement, while no correlation was found with the amount of mandibular setback. Conclusions: Combined maxillary advancement and mandibular setback surgeries lead to an increase in the anteroposterior dimension of the oropharyngeal airway. Which is positively correlated to the amount of maxillary advancement only. Introduction Skeletal class III malocclusion is manifested as a discrepancy in the anteroposterior relationship of the maxilla and mandible. The severity of the deformity, the amount of the desired correction, and the expected facial improvement after surgery, affect the treatment of choice. Surgical correction of skeletal class III cases by a combination of bimaxillary surgery has a great effect on the facial esthetics and the patient’s self-esteem. However, it has another functional effect on the oropharynx. The complex anatomy of the oropharynx is pivotal to its function. The pharyngeal muscle tone essential to its patency is reduced during sleep, thus substantiating the role of proper pharyngeal anatomy to guard against airway collapse. Therefore objectives as improving occlusion and aesthetics, should be planned with attention to the pharyngeal function. Several studies reported a reduction of the pharyngeal airways after mandibular setback surgery. Long follow-up showed maintenance of this reduction. At the same time, Mao et al found that although there was some increase in both the airway space width and area during the follow-up period, they did not increase to their origi

Objective This study aims to evaluate the stress distribution and displacement that result from the use of the isoglide eruption spring during palataly impacted canine traction using three-dimensional finite element analysis. Materials and methods: A three-dimensional finite element model of the maxilla was developed from a scanned dry model of skull (meditT510). Traction was simulated With the isoglide eruption spring which is made of nickel titanium (1.2 N). Von Mises stress distributions and initial displacements of the palataly impacted canine and adjacent teeth were analyzed. Results: The isoglide spring showed 0.293MPa stresses on the palataly impacted canine. The stress distribution decreased as the distance from the impacted canine increased. The stresses were (0.225MPa) on the adjacent lateral incisor and (0.002MPa) on the first premolar. The isoglide spring showed a total displacement of (0.0002 mm) on the impacted canine. Conclusion: The iso glide eruption spring is efficient in traction of palatally impacted canines with the stresses on the neighboring teeth decreased as the distance from the impacted canine increased .

Objective: The aim of the study was to compare the nasal cavity width changes following slow and rapid activation of miniscrew-supported maxillary expander. Materials and Methods: Twenty-four adolescent patients having transverse maxillary deficiency were included in the study. All the patients received a maxillary expander supported on four palatal miniscrews. The patients were equally divided into two groups: Group I (slow expansion, once every other day), Group II (rapid expansion, twice per day). Cone beam computed tomography (CBCT) scans were made before expansion (T1) and at the end of the retention period after removing the expanders (T2). Measurements were performed on coronal cuts of the CBCT. Statistical analysis was performed. Results: Both activation rates resulted in a significant increase of the nasal cavity width. No significant difference was found between the two groups. Conclusion: Both slow and rapid activation protocols of miniscrew-supported maxillary expanders are effective in increasing the nasal cavity width.

The objective of this study was to find an association between serum Vitamin D levels and pain perception in orthodontic patients after initial bond-up. Materials and methods: Sixty four patients visiting the hospital for orthodontic treatment were included in this study. Serum vitamin D levels were checked before bondup using ELISA method. Maxillary arch bond-up was done and a 0.12 NiTI (Nickel Titanium) wire was placed for initial leveling and alignment. A Visual Analogue scale (VAS) was used for pain assessment on day1, 3 and 7 after initial bonding. Results: No significant correlation was found between serum vitamin D levels and Orthodontic pain perception on all three days. Patients with severe deficiency of vitamin D gave a higher mean pain score compared to patients with mild deficiency or optimum levels. Females reported higher pain than their male counterparts in 10-20 years age group. Female patients also displayed lower mean vitamin D levels than their male counterparts. Conclusion: There was no significant and direct correlation between serum Vitamin D levels and the perceived level of pain by orthodontic patients.

Digital casts were obtained by two methods; Intraoral scanning by carestream intraoral scanner CS3600 powder free and model scanning by cast scanner Sirona InEos X5 scanner. Three study groups were obtained; Group 1: conventional dental casts ,group 2: digital casts obtained with powder free intraoral scanning and group 3: digital casts obtained by cast scanner. Intercanine and intermolar widths in addition to individual tooth measurements were made using Viewbox program for digital casts and digital caliper for the plaster cast. Results: No statistical significant difference between three groups regarding all measurements had been found. Conclusion:The results of this study confirm the potential of intraoral scanning to acquire data as accurate as alginate impressions as well as scanned digital casts for orthodontic applications","PeriodicalId":305086,"journal":{"name":"Egyptian Orthodontic Journal","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127240318","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}
