Abstract

The examination of static and dynamic occlusal relationship are important in orthodontic diagnosis. Thus, this study aims to analysis the difference of occlusal cant and favored chewing side. This is cross-sectional study of 70 healthy dental students Universitas Sumatera Utara with complete dentition and have no orthodontics treatment history. The position of tongue spatula across on occlusal of both first bicuspids to assess the existence and degree of the canting occlusal based on extra-oral photograph. The occlusal cant positive if it coincided to inter pupil as transversal references and sectioned with facial midline as a vertical reference more than 3º. A modified direct method- visual observation was done to assess the favored chewing side. A chi-square test with p level 0.05 in evaluation of the null hypothesis that states there was a difference of occlusal cant and favored chewing side in those subjects. From 36 subjects with cant occlusal positive, there were 26 subjects with and 10 subjects without favored chewing side. Then, from 34 subjects with cant occlusal negative, there were 14 subjects with and 20 subjects without favored chewing side. There was a significant difference (p=0.017) between occlusal cant and favored chewing side. Subjects with complete teeth showed that favored chewing side tendency of 3,714 more often had an occlusal cant positive compared to favored chewing side negative. In conclusion, the significant difference of occlusal cant and favored chewing side in subjects with complete dentition can be considered as a preliminary study in order to understand the complexity of development of mandibular asymmetry.

Abstract

Background: The development of radio diagnostics in orthodontics is still a challenge in treating skeletal anomaly with facial asymmetry. The assessment of skeletal symmetry, which can be obtained by frontal radiographs such as panoramic radiograph and posteroanterior cephalograph, is still limited. Purpose: The aim of this study is to evaluate panoramic radiograph and posteroanterior cephalograph in measuring the vertical mandibular asymmetry based on Kjellberg technique. Methods: This study was a cross-sectional study of 43 pre-treatment panoramic radiographs and posteroanterior cephalographs from dental faculty students at Universitas Sumatera Utara between 18–25 years old. The subjects have fully erupted permanent teeth until the second molar and complained about facial asymmetry. The validity and reliability of vertical mandibular asymmetry of Kjellberg technique with Cliniview software in both radiographs used Cohen-K analysis. Results: The measurement of vertical mandibular asymmetry showed no significant differences using panoramic radiograph and posteroanterior cephalograph (0.073-0.321 > 0.05). Conclusion: The vertical mandibular asymmetry analysis with Kjellberg technique in panoramic radiograph is potent as an adjunctive diagnostic tool in vertical mandibular asymmetry.

Abstract

Correction of skeletal Class II malocclusion with camouflage orthodontic treatment generally requires the extraction of the maxillary first premolars to provide space for retraction of the maxillary incisors. Retraction of incisors changes the position of the incisors and the dimensions of the dental arch, which can cause changes in tongue posture and affect the upper airway. The purpose of this study was to determine the relationship between premolar extraction on the dimensions of upper airway and tongue posture in skeletal Class II malocclusion. This study was designed as a retrospective cohort using lateral cephalometric radiographs before and after orthodontic treatment. The samples in this study consisted of 44 samples of adult patients (n = 44) aged 18-40 years, who were divided into 2 groups: 22 subjects treated without premolar extraction and 22 subjects treated with premolar extraction. Lateral cephalometric radiographic analysis were used to measure the dimensions of the upper airway by analyzing superior posterior airway space (SPAS), middle airway space (MAS), inferior airway space (IAS), vertical airway length (VAL), and tongue posture (tongue length and height tongue) using imageJ software. No Statistically significant different changes were observed as seen from the following results: SPAS (p = 0.709), MAS (p = 0.365), IAS (p = 0.562), (p = 0.401), tongue length (p = 0.578), tongue height (p = 0.086) in the sample group without extraction premolar. No significant alterations in the upper airway and tongue posture measurement were observed in the sample group with extraction premolar. Premolar extraction with retraction on upper incisors did not affect upper airway dimensions and toung posture in skeletal Class II malocclusion.
