Abstract

Periodontal ligaments are one of the supporting tissues of teeth that undergo remodeling during the tooth movement process. Vitamin C deficiency inhibits the regeneration of collagen fibers, which are important in tissue remodeling that affects the widening of the periodontal ligament space during the process of tooth movement. The widening of periodontal ligament space can be seen by taking radiographic photos. The purpose of this study was to determine the width of the periodontal ligament space of guinea pigs by administering vitamin C, without vitamin C, and the differences between the two groups. Those samples were grouped into four groups with observation times of 1, 4, 7, and 10 days, and each group consisted of the control group and vitamin C group. Those samples were paired with orthodontic separator rubber. After the specified time was completed, periapical radiographs were taken, and the width of the periodontal ligament space was measured by using Image J software. The mean width of the periodontal ligament space in the vitamin C group was smaller than the control group. Based on this study, it can be concluded that vitamin C has an effect on reducing periodontal ligament space in the process of tooth movement. Key words: periodontal ligament space, vitamin C, tooth movement, remodeling

Abstract

Background: Camouflage treatment of skeletal Class II malocclusion can be performed using extraction or non-extraction techniques. These treatments can cause changes in occlusal plane. Steep occlusal plane during corrective treatment generally relapses after active orthodontic treatment, resulting in unstable interdigitation. Purpose: This study aims to determine and evaluate changes in occlusal plane inclination in skeletal Class II malocclusion cases using extraction or non-extraction techniques of the permanent maxillary first premolar. Methods: The samples consisted of initial and final cephalometry of 40 adult patients with skeletal Class II malocclusion divided into two groups, namely extraction of the permanent maxillary first premolar and non-extraction group. The inclination of occlusal planes in both groups was measured using the ImageJ software, then the factors associated with these changes were observed. Furthermore, the occlusal plane inclination was compared between the extraction and non-extraction groups by using t-test. Results: The occlusal plane inclination in the non-extraction group increased slightly, while the inclination in the extraction group increased significantly (p = 0.017, p-value < 0.05). However, there was no correlation found in the occlusal plane inclination between the extraction and non-extraction groups (p = 0.07, p-value < 0.05). Conclusion: Class II malocclusion correction with either extraction or non-extraction of the maxillary first premolar increased the inclination of the occlusal plane. This study indicated that control of the occlusal plane inclination is highly essential.

Abstract

Background: Standard edgewise and preadjusted Roth are two bracket types widely used for orthodontic treatment. Whether one of these bracket types offers better treatment results than the other requires further evaluation. The Objective Grading System created by the American Board of Orthodontics (ABO) is one of the most reliable indices used to evaluate treatment outcomes. Objectives: To determine the effects of using two different bracket types on treatment outcomes by using the Objective Grading System. Methods: The sample for this study consisted of 64 randomly selected post-treatment dental casts and panoramic radiographs. Of these samples, 32 were treated with a standard edgewise bracket, and the others were treated with a preadjusted Roth bracket. Patient samples were included if they had non-extraction Class I malocclusion (minor crowding < 4 mm for both bracket types, ANB = 2º ± 2º), no history of dental trauma, complete teeth (except third molars), and no growth or development disturbances. All samples were evaluated using eight parameters of the Objective Grading System and statistically analyzed using Mann–Whitney and chi-squared tests. The score range for each tooth in each parameter was 0 – 2. Results: The total score was 19.00 ± 12.00 for the standard edgewise bracket and 15.00 ± 7.00 for the preadjusted Roth bracket, with no statistically significant differences between the two bracket types (p = 0.149). There were also no statistically significant differences in the scores of the eight parameters of the Objective Grading System between these brackets (p > 0.05). The highest score was found for the buccolingual inclination parameter, and the lowest score was for interproximal contacts. Conclusion: According to the Objective Grading System, there are no statistically significant differences between the orthodontic treatment outcomes obtained using a standard edgewise or a preadjusted Roth bracket.

Abstract

Closed coil spring is an additional tool in a fixed-orthodontic treatment. NiTi is an orthodontic alloy that has shape memory and elasticity features, while stainless steel has properties of malleability, low friction between wire-bracket, as well as easy soldering and welding. Various properties of closed coil springs have been widely studied, but research on the stretching time remains unclear. This study aimed to determine the effect and differences in the stretching time for 7 days, 14 days, 21 days, and 28 days on the force magnitude of NiTi and stainless-steel (SS) closed coil spring. A 7 x 5 x 1 cm acrylic blocks with 1 cm acrylic posts were employed, and 25 mm closed coil springs were attached to the acrylic posts using modified T-sticks. The springs were immersed in an artificial saliva with pH of 6.75 for 7, 14, 21, and 28 days in an incubator at 37 °C. The container was removed from the incubator and the force was measured using a universal testing machine. Kolmogorov-Smirnoff test was carried out to analyze parametricdata, while independent T-test was used to determine the difference between each group. There was a significant effect of stretching time on the force magnitude of the SS closed coil spring in all the groups (p < 0.05). There was no significant effect of stretching time on the force of the NiTi closed coil spring on days 7, 14, and 21 (p > 0.05) but there was a significant effect on day 28 (p < 0.05). A significant effect between the ratio of the SS and NiTi closed coil spring (p < 0.05) was confirmed. Longer stretching time indicated a force loss in the SS closed-coil spring, while the NiTi spring had a more stable force which implies a formidable treatment-time for orthodontic treatment.

Abstract

Background: Prolonged airway obstruction during facial growth can influence the development of craniofacial structures. Conversely, craniofacial deformities may contribute to reduced airway dimensions. Understanding the relationship between craniofacial morphology and pharyngeal airway space is essential, particularly in individuals with altered breathing patterns such as mouth breathing. Objective: This study aimed to determine the differences and relationships between craniofacial structures and pharyngeal airway dimensions in patients with mouth breathing compared to those with normal nasal breathing. Methods: This study employed a descriptive-analytic research design. A total of 20 lateral cephalograms were analyzed10 from patients with normal breathing and 10 from mouth-breathing patients, all presenting with skeletal class II malocclusion. Landmarks were identified manually, and measurements were carried out using the CorelDRAW application. The Unpaired T-test was used to assess differences between groups. The Pearson correlation test was used to examine the relationship between craniofacial structures and airway dimensions in the mouth-breathing group. Results: Significant differences were found in mandibular structure and the oropharyngeal U-MPW plane angle (p 0.05) between mouth breathers and nasal breathers. However, no statistically significant correlation was observed between craniofacial measurements and pharyngeal airway dimensions within the mouth-breathing group. Conclusion: This study concludes that increased anteroposterior skeletal measurements and vertical facial height are not significantly associated with narrowing of pharyngeal airway dimensions in mouth-breathing patients. Further studies with larger sample sizes are recommended to explore this relationship more comprehensively.
