The present study was done to evaluate and compare the effect of probiotic toothpaste in reducing streptococcus mutans and to improve periodontal status of patients who are undergoing fixed orthodontic treatment. A total of 60 participants undergoing fixed orthodontic treatment in age range of 14-29 years were selected to receive probiotic toothpaste for a 30 days period. Participants were examined at 2 time points: base line (start of the study) T0 and after 30 days (T 1) of using probiotic toothpaste. In both the groups, S. Mutans Colony Count and Orthodontic Plaque Index was evaluated. At T0, the mean S. mutans colony count was found to be 63.31± 27.23x10-2 CFU/ml. At T1 the mean S. Mutans colony count was found to be 29.70 ± 15.41x10-2 CFU/ml. The mean Plaque Index was found to be 1.23+0.53 at T0. After using probiotic toothpaste twice daily for a period of 1 month (T1) the mean Plaque Index was found to be 0.11±0.32. Use of probiotic toothpaste twice daily has been found useful in reducing S. Mutans colony count after using for a period of 1 month.
本研究旨在评估和比较益生菌牙膏对固定正畸治疗患者减少变形链球菌和改善牙周状况的效果。共有60名年龄在14-29岁之间接受固定正畸治疗的参与者被选中接受益生菌牙膏,为期30天。参与者在两个时间点接受检查:基线(研究开始)T0和使用益生菌牙膏30天后(t1)。评估两组变形链球菌菌落计数和正畸菌斑指数。T0时,平均变形链球菌菌落计数为63.31±27.23 × 10-2 CFU/ml。T1时,平均变形链球菌菌落计数为29.70±15.41 × 10-2 CFU/ml。T0时的平均斑块指数为1.23+0.53。每天使用两次益生菌牙膏,持续1个月(T1)后,平均斑块指数为0.11±0.32。每天使用两次益生菌牙膏,在使用1个月后,可有效减少变形链球菌菌落计数。

Impacted canines are a matter of concern in the treatment of malocclusion. After the third molars, maxillary canines are considered the most commonly impacted teeth with a frequency of 0.27% among Japanese and 2.4% among Italians. Unilateral impactions are more prevalent than bilateral impactions. The impacted canine can be detected with palpation, and radiographic techniques such as IOPA (Tube shift technique), panoramic radiographs, occlusal radiographs, and CT. The mesiodistal position and angulation of the canine crown on a panoramic radiograph can possibly predict treatment success. Various treatment approaches are considered depending on the mesiodistal angulation and position of the impacted canine. An auxiliary spring in the buccal region of the impacted canine designed by Kornhauser Et al has advantages such as avoidance of usage of palatal arches, and additional lab work such as soldering thereby incurring at least an extra clinical visit. This case report showcases the treatment of a 13-year-old growing male patient with a palatally impacted right maxillary canine using a Labial auxiliary spring and correction of molar relation using an Infra Zygomatic Crestal Implant.
在治疗错牙合时,埋伏的犬科是一个值得关注的问题。在第三磨牙之后,上颌犬齿被认为是最常见的阻生牙齿,日本人和意大利人的频率分别为0.27%和2.4%。单侧嵌塞比双侧嵌塞更为普遍。阻生犬可以通过触诊、影像技术如IOPA(管移位技术)、全景x线片、咬合x线片和CT来检测。犬牙冠的近远端位置和角度在全景x线片上可以预测治疗的成功。不同的治疗方法是考虑取决于中远端角度和位置的影响的犬科。Kornhauser等人在患侧犬颊区设计的辅助弹簧具有避免使用腭弓和额外的实验室工作(如焊接)的优点,因此至少需要额外的临床访问。本病例报告展示了一个13岁的男性患者的治疗与腭阻生右上颌犬使用唇辅助弹簧和矫正磨牙关系使用颧下嵴种植体。

To assess and compare anteroposterior jaw dysplasia indicators i.e. (Wits-appraisal, ANB-angle, β(Beta)-angle, W-angle, YEN-angle and π(Pi)-angle) in Angle's Class I molar relation subjects with normal overjet of central India.Sum of 40 lateral cephalograms were traced in line with the inclusion criteria of Angle’s Class I molar relation subjects. Subjects had to be between the ages of 18 and 30 and have a normal overjet and aligned arches. We measured and compared the Wits-appraisal, ANB-angle, (Beta)-angle, W-angle, YEN-angle and Pi-angle. The statistical package for social sciences (SPSS) 20.0 version was used to examine the data. We used descriptive statistics. The Spearman's correlation coefficient was used to evaluate the correlation between the variables. Statistics were judged as significant at a p-value of 0.05. 95% of the confidence interval was chosen. The result showed descriptive statistical representation for the norms of Wits-appraisal, ANB-angle, Beta-angle, Yen-angle, W-angle, and Pi-angle for the Central India population. We found a high correlation of ANB-angle with YEN-angle, ANB-angle and Pi linear, ANB-angle and W-angle, Beta-angle and W-angle, YEN-angle and W-angle and Pi-angle and Pi linear. Among the angles used for the comparative evaluation for the prediction of anteroposterior jaw dysplasia, W-angle and YEN-angle had the utmost accuracy, whereas Beta-angle had the least. Therefore, YEN-angle and W-angle are reliable in our practice in the prediction of anteroposterior jaw dysplasia in the Central India population.
评价和比较印度中部地区正常上突的角I类磨牙关系受试者的前下颌发育不良指标(wits -评价、anb角、β(β)角、w角、yen角和π(Pi)角)。根据Angle 's I类磨牙关系受试者的纳入标准,追踪40张侧位头颅图像。受试者的年龄必须在18到30岁之间,有一个正常的覆盖和对齐的弓。我们测量并比较了wits -评价角、anb角、(Beta)角、w角、yen角和pi角。采用社会科学统计软件包(SPSS) 20.0版本对数据进行检验。我们使用描述性统计。Spearman相关系数用于评价变量之间的相关性。p值为0.05时,判定统计学意义显著。选取95%的置信区间。结果表明,印度中部人口的wits -评价、anb -角、beta -角、yen -角、w -角和pi -角的规范具有描述性统计代表性。我们发现anb角与yen角、anb角与Pi呈线性关系、anb角与w角、beta角与w角、yen角与w角、Pi角与Pi呈线性关系。在预测前后颌骨发育不良的比较评价角度中,w角和yen角的准确度最高,而beta角的准确度最低。因此,yen角和w角在我们预测中印度人群前后颌发育不良的实践中是可靠的。

The objective of this study was to evaluate apical stress distribution during intrusion of the maxillary central incisor with different inclinations in the labial and lingual appliance systems using a three-dimensional finite element model.The three-dimensional finite element models of the maxillary central incisor were produced with 25 ° (normoclined), 30 ° (proclined), and 20 °(retroclined) inclinations. Each incisor model was subjected to an intrusive force of 15cN. The stress level at the apex was calculated in terms of maximum principal stresses.The stress distribution at the apex and cervix was lower in the labial compared to the lingual appliance system for the maxillary central incisor models with an inclination of 25° (normoclined) and 30° (proclined). Whereas the maxillary central incisor model with 20° (retroclined) inclination in the lingual appliance system showed the maximum stress in the cervical region.During intrusion, no significant differences in stress patterns were seen at the root apex in normoclined and proclined maxillary central incisor models in either of the appliance systems, except for the retroclined central incisor model which showed maximum stresses in the cervical region.
本研究的目的是利用三维有限元模型来评估上颌中切牙在不同倾斜度下在唇部和舌部矫治器系统中牙尖应力的分布。制作上颌中切牙25°(正斜)、30°(前斜)和20°(后斜)倾斜的三维有限元模型。每个切牙模型承受15cN的冲击力。顶点处的应力水平按最大主应力计算。上颌中切牙模型倾斜25°(正斜)和30°(斜斜),与舌矫治系统相比,上颌中切牙在唇部的应力分布较低。而舌矫治器系统倾斜20°(后倾)的上颌中切牙模型在颈椎区域的应力最大。在侵入过程中,除后倾中切牙模型在颈椎区域显示出最大应力外,两种矫治系统中正倾和前倾上颌中切牙模型的根尖应力模式均无显著差异。

The current study aims to provide quantitative and qualitative information about the prevalence of dental malocclusions among dental students of Kabul University of Medical Sciences (KUMS) in the orthodontics department of Ali Abad Teaching Dental Clinic that evaluates the relationship of malocclusion between gender and the major causes of malocclusion in society among genders and the tendency of the community toward the treatment of dentoalveolar anomalies. This study was a cross-sectional survey that was done randomly among 133 students, 68 male (51.12%) and 65 female (48.87%), in an age range of 18–25 years old at Kabul University of Medical Sciences, Ali Abad teaching dental clinic faculty of dentistry. show the dental malocclusion classes due to “angle" classification in females in Class I (53.48%), Class II (21.4%), and Class III (23.07%), while in males in Class I (48.33%), Class II (6.66%), and Class III (43.33%). The prevalence rate of crowding was 33% in males and 43% in females. It has been studied and analyzed separately that the most common oral problems in females were dental caries (53.84%). According to our survey (65 female participants), no one had periodontitis, while in males, plaque was at a rate of 28.97%, and the least common was gingivitis (6%), respectively. The occurrence of dental trauma in boys and heredity in girls may be the most important factors for dental malocclusion. Girls were more interested in orthodontic treatments, which may be because they pay more attention to beauty than boys. Moreover, crowding had the highest rate among participants, followed by deep, open bites and edge-to-edge bites.
本研究旨在提供有关Ali Abad教学牙科诊所正畸科喀布尔医科大学(KUMS)牙科学生牙齿错颌患病率的定量和定性信息,评估性别间错颌的关系以及社会中性别间错颌的主要原因以及社区对牙槽畸形治疗的倾向。本研究采用横断面调查方法,随机抽取喀布尔医科大学阿里阿巴德牙科教学诊所牙科系18-25岁学生133名,其中男68名(51.12%),女65名(48.87%)。因“角度”分类导致的错牙合分类中,女性为I类(53.48%)、II类(21.4%)、III类(23.07%),男性为I类(48.33%)、II类(6.66%)、III类(43.33%)。人群拥挤的患病率男性为33%,女性为43%。分别研究和分析,女性最常见的口腔问题是龋齿(53.84%)。根据我们的调查(65名女性参与者),没有人患有牙周炎,而在男性中,斑块的发生率为28.97%,最不常见的是牙龈炎(6%)。男孩的牙外伤和女孩的遗传可能是导致错牙合的最重要因素。女孩对正畸治疗更感兴趣,这可能是因为她们比男孩更注重美。此外,在参与者中,拥挤的比例最高,其次是深的,开放的咬和边缘到边缘的咬。

Cysts of jaw present as swellings of jaws and midface. Of different varieties, dentigerous cyst is most common type of noninflammatory odontogenic cyst. Dentigerous cysts are generally associated with crowns of impacted or unerupted permanent teeth. Here we present a case of dentigerous cyst in 13‑year‑old female child, which was successfully treated with conservative therapy. Patient also reported after one and half year with protruding teeth and retained deciduous right upper canine & impacted permanent canine. This case report also presents orthodontic management of retained deciduous canine and impacted permanent canine.
下颚囊肿表现为下颚和面部中部的肿胀。在不同种类中,牙源性囊肿是最常见的非炎症性牙源性囊肿。含牙囊肿通常与阻生或未出牙的恒牙冠有关。我们报告一例13岁女童的含牙囊肿,经保守治疗成功。患者也报告一年半后牙齿突出,保留乳牙右上牙和恒牙埋伏。本病例报告还介绍了保留乳牙和阻生恒牙的正畸治疗。
