Abstract

Model study is one of the standard orthodontic components which is important for diagnosis and treatment plan, but in some patients with the high gag reflex, it will be difficult to get this kind of study models. The existence of a new device which is able to show the condition of patients mouth in three space areas (axial, sagittal, and coronal) is expected to be an alternative when a study model is difficult to get. The purpose of this study is to find out whether or not there are any differences on the size of canines mesiodistal, first and second premolar resulted from CBCT imaging with Moyers analysis on the study models. The method of the research is comparative descriptive. Measurements are made on 10 CBCT imaging results and 10 study models. The mesiodistal size, the result of CBCT imaging is measured by the available computer program and also the mesiodistal size of the study models is measured using a sliding compass, and then the size of canines, first and second premolar teeth resulted from CBCT imaging are compared to the result of Moyers method analysis on the study models. The t-test is used to find out if there is a difference between teeth size value between the CBCT imaging with the study models. The significance is determined based on the p-value < 0,05. The statistical test result shows a significant difference between the size of canines mesiodistal, first and second premolar teeth, the result of CBCT imaging and the Moyers analysis result in the study models in which t count > t table.

Abstract

The aim of an orthodontic treatment is to achieve aesthetic, dental health and the surrounding tissues, occlusal functional relationship, and stability. The success of an orthodontic treatment is influenced by many factors, such as diagnosis and treatment plan. In order to do a diagnosis and a treatment plan, medical record, clinical examination, radiographic examination, extra oral and intra oral photos, as well as study model analysis are needed. The purpose of this study was to evaluate the differences in dental arch form between level four polynomial and pentamorphic arch form and to determine which one is best suitable for normal occlusion sample. This analytic comparative study was conducted at Faculty of Dentistry Universitas Padjadjaran on 13 models by comparing the dental arch form using the level four polynomial method based on mathematical calculations, the pattern of the pentamorphic arch and mandibular normal occlusion as a control. The results obtained were tested using statistical analysis T student test. The results indicate a significant difference both in the form of level four polynomial method and pentamorphic arch form when compared with mandibular normal occlusion dental arch form. Level four polynomial fits better, compare to pentamorphic arch form.

Abstract

This research is aimed at observing whether there are differences in the measurement results between dental arch length and arch length measured manually and by using computer software, i.e. Corel Draw 12, in study model cast as well as the measurement speed in both techniques. The method used in this research is the descriptive comparative method. The measurement is performed to 52 study model cast samples with the Spee Curve depth of < 1.5 mm, between 1.5 and 3 mm, > 3 mm. The measurements are performed using 2 techniques: a manual technique using a calliper and by using Corel Draw 12, a computer program with a computer scanner. The t-test statistic is used to reveal whether there are differences in the measurement results between the two techniques and which method needs shorter time. Statistically, there are significant differences either in the speed of the measurement or the results of the measurement using both techniques where t-calculated > t table. The deeper the Spee curve, the more different the results from the manual technique and computed technique. The differences are in the range of 0.32 to 0.52 mm for dental arch length and 0.33 to 0.43 mm for arch length. These differences are still acceptable clinically. By referring to the results of this research, it is expected that computer usage can be increased and become an alternative against manual technique of measurement.

Abstract

The purpose of this study was to examine the stability of orthodontic treatment results in dentoskeletal class I malocclusion treated with and without extraction of four premolars and to compare the stability of treatment result between those groups. Occlusal relationship after treatment and six-month post retention were measured on dental cast using The Objective Grading System Index at Orthodontic Specialist Clinic, Faculty of Dentistry Universitas Padjadjaran. The analytic descriptive study was carried out on 30 samples that comprised 14 samples were treated without extraction of four premolars and 16 samples were treated with extraction of four premolars. ABO Measuring Gauge was used to measure seven variables: tooth alignment, the height of the marginal ridges, buccolingual inclination, occlusal relationships, occlusal contacts, overjet, and interproximal tooth contacts. The results were statistically analyzed with the Wilcoxon rank test to test the difference of The Objective Grading System Index between posttreatment and postretension. Mann-Whitney U test was applied to determine the difference between the group with the extraction of four premolars and the group without extraction of four premolars. The level of significance was set at 0.05. The results of this study showed these following variables: tooth alignment, occlusal contacts, and overjet were unstable at the group with the extraction of four premolars, while only tooth alignment was found to be unstable in the group without extraction of the four premolars. Mann-Whitney U test did not show statistically significant difference in stability comparison test between the groups.

Abstract

Orthodontic treatment has a main purpose to reach balanced functional occlusion and create a harmonic esthetic face. But several studies indicates that orthodontic treatment influence smile esthetics, especially smile arc and buccal corridor. One-third of the treated patients showed a flat smile arc and orthodontic treatment with extraction resulted in excessive buccal corridors. The purpose of this research is to evaluate the difference of the Objective Grading System index, developed by the American Board of Orthodontics (ABO) and smile aesthetics in patients with Class I dentoskeletal malocclusion before and after orthodontic treatment. Twenty dental casts, panoramic radiographs and grouped pre and post-treatment. Dental casts and panoramic radiographs are scored according to the guidelines of the Objective Grading System. Extra-oral photographs were assessed by researcher using modified Goldstein dentofacial analysis. Result of measurements were evaluated with statistical t-test. Results of the research indicates Objective Grading System index and also score of smile esthetics before and after orthodontic treatment shows difference statistically (for Objective Grading System index P = -1121 > 2.09 and for smile esthetics P = 5.15 > 2.09). But extremely weak relationship was found between Objective Grading System index and Aesthetics smiles (231).

Abstract

Orthodontic treatment could influence alveolar bone height. The longer the treatment, the more effect it will be. The purpose of this study was determined the differences in alveolar bone height at the canine, second bicuspid, mandibular first molar in the case of mandibular premolar extraction with different treatment duration. This study is a retrospective – comparative analytic study, involving 17 samples which have finished orthodontic treatment at FKG Unpad PPDGS orthodontic clinic. The alveolar bone height was determined from panoramic x-rays obtained by measuring the ratio of alveolar crest and the cemento enamel junction to the tooth cusp (Bjorn method). The results of the study were then analyzed using t-student test with Pvalue=0.05, showed a significant correlation in alveolar bone height reduction. In the group less than 2-years treatment, there was a reduction in alveolar bone height only at the mesial side of tooth 35 while there was a significant reduction at the distal canine, the mesial-distal second bicuspid and the mesial-distal side of the mandibular first molar in a group more than 2 years-treatment. This study concluded that there was a significant influence on the duration of treatment and alveolar bone height reduction in the group more than 2-years treatment.

Abstract

Introduction: Power chains is the common device used in fixed orthodontic treatment. Force decay in power chains is a problem that can affect the teeth movement due to a continuous force cannot be maintained. Force decay in power chain can be affected by the use of alcohol-containing mouthwash or alcohol-free mouthwash. The objective of this study was to determine the effect of alcoholic-containing mouthwash, alcohol-free mouthwash, and artificial saliva towards the power chains force decay. Methods: This research was an experimental analytic laboratory in-vitro with the comparative approach. The sample in this study were 40 power chain, short A (SA); 40 power chain, short B (SB); 40 power chain, long A (LA); and 40 power chain, long B (LB), which divided into 5 groups that were consecutively exposed to the artificial saliva as control group; Minosep® with 0.1% of chlorhexidine gluconate; Listerine® with 0% of alcohol; Hexadol® with 9% of alcohol; and Listerine® with 26.9% of alcohol. The measurement of force decay was performed with digital force gauge on day 0, 1, 14, and 28. The statistical analysis was done by using the Wilcoxon and Mann-Whitney tests. Result: There was a significant difference (p<0.05) between the force decay of power chain that exposed to the alcohol-containing mouthwash, alcohol-free mouthwash, and the artificial saliva. Conclusion: The force decay level of power chain that exposed to an alcohol-containing mouthwash was higher compared to the force decay level of power chain that exposed to an alcohol-free mouthwash and an artificial saliva.
