Introduction: The aim of the study was to compare pain relief in temporomandibular disorder (TMD) patients with or without lifestyle modification.

Materials and methods: This randomized clinical trial was performed on patients with TMD, who did not regularly exercise or listen to music. The participants were allocated into two groups. In the treatment group, the participants were instructed to exercise five times or more per week (30 minutes per session) and listen to the music of their choice five times or more per week (15 minutes per session) for 12 weeks. In the control group, the participants had their usual lifestyle without any modifications. The participants were examined for clicking and crepitus in the joint and maximum mouth opening before and after the intervention. The pain severity was also documented based on a visual analog scale.

Results: Thirty five patients were studied in each group. Twelve weeks after the intervention, the mean pain severity was 2.70 ± 0.73 in the treatment group and 4.63 ± 0.77 in the control group. The results of data analysis demonstrated a significant difference between the two groups regarding the mean pain severity at 12 weeks after the intervention (P <.001).

Conclusions: Lifestyle modification through physical exercise and listening to music may reduce pain in TMD patients.

简介该研究旨在比较颞下颌关节紊乱症(TMD)患者在改变生活方式或不改变生活方式的情况下疼痛缓解情况:这项随机临床试验的对象是不经常锻炼或听音乐的 TMD 患者。参与者被分为两组。在治疗组,参与者被要求每周锻炼五次或五次以上(每次 30 分钟),每周听五次或五次以上自己选择的音乐(每次 15 分钟),为期 12 周。在对照组中,参与者的生活方式与平常一样,没有任何改变。在干预前后,对参与者的关节咔嗒声和吱吱声以及最大张口量进行检查。此外,还根据视觉模拟量表记录了疼痛的严重程度:每组研究了 35 名患者。干预 12 周后,治疗组的平均疼痛严重程度为 2.70 ± 0.73,对照组为 4.63 ± 0.77。数据分析结果表明,干预 12 周后,两组患者的平均疼痛严重程度存在显著差异(P 结论:治疗组和对照组的疼痛严重程度差异显著,而对照组的疼痛严重程度差异显著:通过体育锻炼和聆听音乐来改变生活方式可减轻 TMD 患者的疼痛。

Tooth impaction is a frequent phenomenon, and the prevalence and distribution of this entity in different regions of the jaws may vary considerably. The third molars, maxillary canines, maxillary and mandibular premolars, and maxillary central incisors are the most commonly affected teeth. Impacted teeth in children and adolescents are rarely associated with pathological changes, but the prevalence of problems has been found to increase in later decades. Impacted teeth are commonly asymptomatic and not associated with any pathologic lesions for years. Proliferative potential of various odontogenic lesions were calculated using Ki-67 labeling index calculation, with the highest index of Unicystic Ameloblastoma followed by Adenomatoid odontogenic tumor, Unicystic Ameloblastoma, followed by the dental follicle. Ki-67 is a marker of cell proliferation, used as an important diagnostic marker in the pathologic differentiation of various lesions. It is always better to orthodontically treat or extract asymptomatic impacted teeth to avoid or to restrict the proliferative capacity of the dental follicle. Treatment decisions about the third molar have important clinical and cost implications.

牙齿嵌塞是一种常见现象,这种现象在颌骨不同部位的发生率和分布可能有很大差异。第三磨牙、上颌犬齿、上颌和下颌前磨牙以及上颌中切牙是最常见的受影响牙齿。儿童和青少年的阻生牙很少伴有病理变化,但问题的发生率在几十年后会有所增加。受影响的牙齿通常没有症状,多年来也没有任何病理变化。利用 Ki-67 标记指数计算各种牙源性病变的增殖潜力,其中单囊性釉母细胞瘤的指数最高,其次是腺瘤样牙源性肿瘤、单囊性釉母细胞瘤,再次是牙泡。Ki-67 是细胞增殖的标志物,在各种病变的病理分型中作为重要的诊断标志物。为避免或限制牙囊的增殖能力,最好对无症状的阻生牙进行正畸治疗或拔除。有关第三磨牙的治疗决定具有重要的临床和成本影响。

A 20-year-old female presents with a painless, progressive, normal color smooth surface sublingual swelling extending to chin that had gradually increased in size over the preceding 2 months, which severely impaired her speech and swallowing. Fine-needle aspiration biopsy was suggestive of benign cystic lesion. Following surgical excision, the mass was found to contain a large amount of sebaceous keratin material removed along with the entire capsule of the cyst. Definitive diagnosis was confirmed with histological examination. We report a case of dermoid cyst treated surgically through an intra-oral approach by preserving and relocating the Wharton's duct using micro-surgical repair to the floor of the mouth, thereby leading to a good cosmetic and functional result for the patient.

一名 20 岁的女性因无痛、进行性、正常颜色、表面光滑的舌下肿物延伸至下巴而就诊,肿物在过去两个月中逐渐增大,严重影响了她的言语和吞咽。细针穿刺活检提示为良性囊性病变。手术切除后发现,肿块中含有大量皮脂腺角蛋白物质,整个囊肿的囊膜也被切除。组织学检查证实了最终诊断。我们报告了一例通过口腔内方法进行手术治疗的类皮样囊肿病例,利用显微外科修复术将沃顿氏管保留并移至口腔底部,从而为患者带来了良好的外观和功能效果。

Since the first reported case in December 2019, COVID-19 has become a worldwide pandemic. Although primarily a zoonotic infection, human-to-human transmission is well reported now and the mode of spread is mainly via respiratory droplets during direct contact or via surfaces contaminated with the virus as it remains viable on the surfaces for a long time. Direct communication and consistent exposure to body fluids such as blood and saliva and the fact that routinely done dental procedures generate aerosols predisposing dental professionals to serious risk for COVID-19 infection. Hence, to ensure the smooth working and safety of dental professionals as well as the patients, a set of directives are of paramount importance. Various guidelines have been released for the efficient operation of dental professionals; however, no such recommendations/directives have been laid out pertaining to dental implants in particular. Here, we are presenting a set of recommendations for managing urgent implant-related treatment procedures.

自 2019 年 12 月报告首例病例以来,COVID-19 已成为一种全球性流行病。虽然主要是人畜共患传染病,但目前人与人之间的传播已有大量报道,传播方式主要是通过直接接触时的呼吸飞沫或被病毒污染的物体表面,因为病毒在物体表面仍可存活很长时间。直接交流和持续接触体液(如血液和唾液),以及牙科常规操作过程中产生的气溶胶,使牙科专业人员面临感染 COVID-19 的严重风险。因此,为确保牙科专业人员和患者的顺利工作和安全,制定一套指令至关重要。目前已经发布了各种指南,以提高牙科专业人员的工作效率;但还没有特别针对牙科植入物的建议/指南。在此,我们将提出一套管理与种植牙相关的紧急治疗程序的建议。

Osteolytic lesions refer to the destruction of any part of bone due to a disease process (pertaining to dissolution of bone, especially loss of calcium). Osteomyelitis is the inflammation of the bone caused by an infecting organism. Although bone is normally resilient to bacterial colonization, events such as trauma, surgery, infections, the presence of foreign bodies, and anemia may disrupt bony integrity and lead to the onset of bone infections. Sometimes, osteomyelitis causes no signs and symptoms or the signs and symptoms are hard to distinguish from other problems. This may be true for children, older adults, and people whose immune systems are compromised. Here, we report a case of chronic intermedullary inflammation of bone in a child.

溶骨病变是指由于疾病过程(与骨骼溶解有关,尤其是钙的流失)而导致的骨骼任何部分的破坏。骨髓炎是由感染性生物体引起的骨骼炎症。虽然骨骼通常对细菌的定植有很强的抵抗力,但创伤、手术、感染、异物存在和贫血等事件都可能破坏骨骼的完整性,导致骨感染的发生。有时,骨髓炎不会引起任何症状和体征,或者这些症状和体征很难与其他问题区分开来。儿童、老年人和免疫系统受损的人可能会出现这种情况。在此,我们报告了一例儿童慢性髓间骨炎病例。

Background: The aim of this study is to evaluate the location and radio morphometric features of the posterior superior alveolar artery (PSAA) in patients undergoing rehabilitation of posterior maxilla and other sinus augmentation surgical procedures by cone-beam computed tomography (CBCT).

Materials and methods: A total of 816 CBCT scans were included. Various radio morphometric measurements were done to assess the PSAA location, diameter, and distances to the sinus floor and alveolar crest.

Results: The PSAA was mostly intraosseous in the maximum in the age group 31-51 years (56%), in males (53.4%), and in dentate patients (57.4%). The artery tends to be wider in older patients. Distances to the sinus floor or the alveolar crest tend to be shorter in women.

Conclusions: This study suggests that CBCT is a valuable pre-surgical tool and the evaluation of the PSAA on CBCT images could reduce the likelihood of excess bleeding during surgery in the maxillary posterior region.

背景:本研究的目的是通过锥形束计算机断层扫描(CBCT)评估接受上颌后牙槽后上动脉(PSAA)修复手术和其他鼻窦增大手术患者的牙槽后上动脉(PSAA)的位置和放射形态特征:共纳入 816 张 CBCT 扫描图像。结果:PSAA 大部分位于上颌窦内,与上颌窦底和牙槽嵴的距离较远:结果:31-51 岁年龄组(56%)、男性(53.4%)和有齿患者(57.4%)的 PSAA 大多位于骨内。年龄较大的患者动脉往往较宽。女性到窦底或牙槽嵴的距离往往较短:这项研究表明,CBCT 是一种有价值的术前工具,在 CBCT 图像上评估 PSAA 可以降低上颌后区手术中出血过多的可能性。

Aim: To analyze the effect of the mandatory helmet rule in helmet usage among motorcycle riders and on facial trauma and to determine the significance of difference in the possibility of facial trauma between the helmeted and non-helmeted motorcycle riders.

Setting and design: A retrospective comparative study conducted in a major trauma center at Uttar Pradesh.

Material and method: Data for the present study was obtained from records of the Emergency Department of Trauma Center, for a period of two months before and after the implementation of The Motor Vehicles Act in UP. The study included patients with a history of non-fatal motorcycle accidents who sustained facial injuries regardless of the presence of injuries to other areas of the body during the study period. Information regarding helmet usage during the accident was also recorded. The results were compared between the pre-law period and post-law period.

Statistical analysis used: Sample t-test was applied to find the level of significance.

Results: Out of 219 injured patients, 152 (69.40%) subjects were not wearing helmets, whereas only 67 (30.59%) subjects were wearing helmets. It was observed that around 68.18% of people stated wearing helmets after law implementation with a statistical significance (P value < 0.05).

Conclusion: Our study shows that the mandatory helmet rule with elevated penalty rates has significantly increased the usage of helmet among the motorcycle riders, and it also proves that the possibility of facial trauma is significantly higher in non-helmeted riders when compared to helmeted riders.

目的:分析强制性头盔规定对摩托车骑手使用头盔的影响以及对面部创伤的影响,并确定戴头盔和不戴头盔的摩托车骑手之间面部创伤可能性差异的显著性:在北方邦的一家大型创伤中心进行的回顾性比较研究:本研究的数据来自北方邦《机动车辆法》实施前后两个月内创伤中心急诊科的记录。研究对象包括在研究期间有非致命摩托车事故史且面部受伤的患者,无论身体其他部位是否受伤。同时还记录了事故中头盔的使用情况。研究结果在立法前和立法后进行了比较:采用抽样 t 检验来确定显著性水平:在 219 名受伤患者中,152 人(69.40%)没有佩戴头盔,只有 67 人(30.59%)佩戴了头盔。据观察,约有 68.18% 的人表示在法律实施后佩戴了头盔,且具有统计学意义(P 值 < 0.05):我们的研究表明,强制佩戴头盔的规定和较高的处罚率大大提高了摩托车骑手对头盔的使用率,同时也证明,与佩戴头盔的骑手相比,未佩戴头盔的骑手面部受创的可能性明显更高。

Pierre Robin sequence poses a great challenge for anesthesiologists during laryngoscopy and intubation, making oxygenation and ventilation difficult. The role of early surgical intervention is recommended for the improvement of the airway and overall survival of the neonate. The situation becomes even more challenging, when the neonate may not be fit for such surgical interventions. The present case posed such a challenge to the team. To the authors' knowledge, the decision to use a face mask as an interim life-saving measure was considered for the first time. This provided a greater window of opportunity for further course of action, only to be later managed by distraction osteogenesis of the mandible. The unconventional use of orthopedic appliances for the management of threatened airways may provide the clinician with time, where further management may be carried out. The present article will explain such a procedure that was carried out as a life-saving measure.

在喉镜检查和插管过程中,皮埃尔-罗宾序列给麻醉师带来了巨大挑战,使氧合和通气变得困难。为了改善气道状况和新生儿的整体存活率,建议尽早进行手术干预。当新生儿可能不适合进行此类手术干预时,情况就变得更具挑战性。本病例就给团队带来了这样的挑战。据作者所知,使用面罩作为临时救生措施的决定是首次考虑。这为进一步的行动方案提供了更多的机会,只是后来通过下颌骨牵张成骨术进行了处理。采用非常规的矫形器来处理受威胁的气道,可为临床医生提供进一步处理的时间。本文将对这一挽救生命的手术进行说明。

Condylar osteomyelitis is a long-standing infection of the condylar head of the mandible. The chronic progression of this disease can lead to the destruction of surrounding bony structures and can ultimately affect function. Currently, in English Literature, there have been few cases published on condylar osteomyelitis. Interestingly, regardless of proximity, there have only been two other reported cases of condylar osteomyelitis subsequent to extractions of the upper maxillary third molar. We report a case of a 27-year-old female who presented with an acute episode of condylar osteomyelitis after a simple extraction of an upper left third molar. Several courses of antibiotics did not alleviate her severe trismus, paresthesia, or extensive preauricular collection. Three surgical interventions showed negative growth on numerous swabs. However, CT scans and an MRI confirmed extensive osteomyelitis along the left head, neck, and the angle of the mandible. Following inpatient IV antibiotics, the patient was discharged with a PICC line to allow for long-term treatment. An improvement in function, pain, and swelling was seen on discharge. However, due to the nature of this disease she was monitored for 2 years and due to joint collapse has been listed for alloplastic replacement.

髁状突骨髓炎是下颌骨髁状突头部的一种长期感染。这种疾病的慢性发展会导致周围骨骼结构的破坏,并最终影响功能。目前,在英文文献中,有关髁状突骨髓炎的病例发表很少。有趣的是,无论距离远近,仅有两例上颌第三磨牙拔除术后发生髁状突骨髓炎的报道。我们报告了一例 27 岁女性的病例,她在简单拔除左上第三磨牙后出现急性髁状突骨髓炎。几个疗程的抗生素治疗并没有缓解她严重的咀嚼障碍、麻痹和广泛的耳前积液。三次手术治疗后,多次咽拭子检查均呈阴性生长。但是,CT 扫描和核磁共振成像证实,左侧头部、颈部和下颌角有广泛的骨髓炎。住院静脉注射抗生素后,患者带着 PICC 管出院,以便进行长期治疗。出院时,患者的功能、疼痛和肿胀均有所改善。然而,由于这种疾病的性质,她需要接受两年的监测,由于关节塌陷,她已被列入异体置换的名单。

Background: Stature or body height is one of the most important and useful anthropometric parameters which determines the physical identity of an individual. Cranium encompasses hard tissue components with approximately immortal behavior, reason being cranial measurements were selected for the present study for estimation of stature.

Objective: This investigation aimed to assess the stature of unknown using cephalometric parameters by creating equations through regression analysis.

Materials and methods: We selected 361 dental students for the present research; among them, 210 were females and 151 were males in the age range of 21-32 years. Stature and cephalic parameters, i.e., fronto-occipital circumference, head length, and head breadth were measured for each contributor following standard methods and techniques. Cephalic Index was calculated by using the formula: Cephalic Index (CI) = (Head width/Head length) ×100. Karl Pearson's correlation coefficient of stature with cephalic parameters was calculated, and regression analysis was done to generate the formulae for stature estimation.

Results: Results indicated that all cephalic measurements have strong correlation with stature, and among them, circumference of head was found to be the most reliable predictor.

Conclusion: Stature of unknown or deceased can be identified using cephalic parameters as an auxiliary practice.

背景:身材或身高是最重要、最有用的人体测量参数之一,它决定了一个人的身体特征。颅骨包括硬组织成分,具有近乎不朽的特性,因此本研究选择测量颅骨来估算身材:本调查旨在通过回归分析建立方程,利用头颅测量参数评估未知者的身材:本研究选取了 361 名牙科专业学生,其中 210 人为女性,151 人为男性,年龄在 21-32 岁之间。我们按照标准方法和技术测量了每位参与者的身材和头型参数,即前枕周、头长和头宽。头指数的计算公式为头宽指数(CI)=(头宽/头长)×100。计算身材与头型参数的卡尔-皮尔逊相关系数,并进行回归分析,得出身材估算公式:结果:结果表明,所有头颅测量值都与身材有很强的相关性,其中头围是最可靠的预测指标:结论:使用头颅参数作为辅助方法,可以确定未知者或死者的身材。
