page no: 30/37 www.ommegaonline.org Vol:4 Issue: 2 Abstract: Introduction: The aim of this study was to analyze and compare the dental lingual arch widths and lengths, alveolar arch within patients with Angle’s Class I (ACI), Class IIdivision1 (ACII) and Class III (ACIII) malocclusions in Chinese patients. Methods: This study was performed using measurements on ninety dental casts with ACI (age: 22.2 ± 3.6), ACII (age: 23.0 ± 3.8), and ACIII (age: 22.0 ± 2.8) malocclusion subjects. Two-way ANOVA post-hoc and nonparametric tests were applied for comparisons in groups and genders. Results: Maxillary canineand premolar alveolar widths and all maxillary lingual lengths were significantly narrower in ACIII (p < 0.05). The mandibular intercanine andintermolar widths were wider and the maxillary intermolar width measurement was larger in ACIII (p < 0.05). Male’s palate height in ACIII was greater than ACII (p < 0.05). Gender differences were also significant in these measurements. Conclusions: Our data showed undergrowth of the maxilla and overgrowth of the mandible and incisor inclined lingual in ACIII; mandibular growth retrusion and maxillary incisor inclined in ACII. Alveolar width was greater in males than females.

Material and methods: Dental students (N=37) at the Universities in Dresden, Leipzig, Berlin, Olomuc and Greifswald participated in this research. A standardized lecture, followed by the web-based Toothguide-Trainer tool (www.toothguide.de) prepares the students for templates matching with the computer aided “Tooth guide-Training-Box” (TTB, VITA Zahnfabrik).After color matching in neutral grey surrounding (reference), the participants repeated the matching on modified TTBs (red, yellow and blue). Color distance to the selected templates (∆E) was calculated confounded by gender and age. The mean and standard deviation (SD), median and the 95 % confidence interval (95% CI) were calculated using Mann-WhitneyU test (α=.05).
材料和方法:来自德累斯顿、莱比锡、柏林、奥洛穆克和格雷夫斯瓦尔德大学的牙科学生(N=37)参与了本研究。一个标准化的讲座，然后是基于网络的牙齿指导-训练器工具(www.toothguide.de)，为学生准备与计算机辅助的“牙齿指导-训练盒”(TTB, VITA Zahnfabrik)相匹配的模板。参与者在中性灰色环境(参考)中进行配色后，在修改后的ttb(红、黄、蓝)上重复配色。计算与所选模板的颜色距离(∆E)，并将性别和年龄混淆。采用Mann-WhitneyU检验计算均数和标准差(SD)、中位数和95%置信区间(95% CI) (α= 0.05)。

Case 1 A 65-year-oldman was referredto Oral and Maxillofacial medicinedepartment of Dental School ofShiraz University of Medical Science with a complaint of swelling on the right side of the mandible. The medical and family history was unremarkable. On careful history evaluation, the patient proposed that he was treated for right posterior mandibular pus discharge by a dentist 3 months ago by tooth 45 and 46 extraction. On intraoral examination, a tender, diffuse swelling (4cm × 5 cm) was presented involving the buccal and lingual aspects of the edentulous ridge of 45, 46 region extending from mesial side of right mandibular first premolar to right mandibular second molar. Ulcer with fibrino leukocytic membrane was seen on the surface, partly was normal in color and partly was red,firm in consistency, 43 and 44 had 3rd grade mobility, 47 and 48 had 2nd grade mobility, with no associated sinus tract or discharge. The right submandibular lymph node was palpable.
