Schwannoma or neurilemmoma is an uncommon, benign peripheral nerve tumor derived from Schwann cells. It is usually a slow growing, asymptomatic, well encapsulated tumor that arises in association with a nerve trunk.Here we present a rare case of Ancient Schwannoma in a 20 year old male. The patient presented with a small, slow growing asymptomatic mass on the dorsal surface of the tongue, present since past 1year. Lesion was completely excised. Diagnosis was confirmed by histopathology and immunohistochemistry.

Adenomatoid odontogenic tumor, fourth most common odontogenic tumor in the Indian population. It is the most common odontogenic tumor associated with impacted teeth. The diagnosis stands important as it is most commonly associated with an impacted maxillary canine. An adenomatoid odontogenic tumor (AOT) is a tumor of epithelial origin that shows duct-like structures and the epithelium forms whorled masses of cells in a scant fibrous stroma. AOT is not a common odontogenic neoplasm and it was first described by Steensland in the year 1905. Initially, AOT was described as pseudoadenoameloblastoma by Dreibladt in the year 1907 and it was considered a distinct entity and some of them believed it to be a variant of ameloblastoma by Stafne in the year 1948.
腺瘤样牙源性肿瘤,印度人口中第四大常见牙源性肿瘤。它是与阻生牙相关的最常见的牙源性肿瘤。诊断是很重要的,因为它是最常见的颌阻生犬。腺瘤样牙源性肿瘤(AOT)是一种起源于上皮的肿瘤,呈导管状结构,上皮在稀少的纤维间质中形成轮状细胞团。AOT不是一种常见的牙源性肿瘤,于1905年由Steensland首次描述。最初,AOT在1907年被Dreibladt描述为假性成釉细胞瘤,并被认为是一个独立的实体,其中一些人认为它是Stafne在1948年提出的成釉细胞瘤的一种变体。

The skeletal anatomy of maxillofacial region is the most complex in the body. Injuries of this region is classified from isolated injuries which involves osseous components to complex maxillofacial injuries involving the entire facial skeleton. The aim of any imaging technique for maxillofacial injury is to evaluate the positions of anatomic elements in precision for both hard and soft tissues in spatial planes. The oldest method of imaging Maxillofacial injuries was the classic x-rays. The challenge of the classical method was the inability to represent all the bone structures of facial skeleton precisely and the very difficulty to access the elements of the soft tissue of face in detailed form. Computed tomography have replaced conventional x-rays and is now a very important tool of imaging for very precise evaluation of maxillofacial trauma and it’s potency with the ability to detect the exact number and site along with the extent of fractures.A systemic self-study was planned to analyze the best choice of imaging techniques for cases of maxillofacial traumatic injuries. With the application of electronic databases we searched PubMed, Google Scholar, Web of Science, Clinical Trial Gov, Medline Plus, health line, John Hopkins Medicine which were published in English language. This systemic self-study have reviewed the facts which were published earlier to determine the ideal choice of imaging techniques for any trauma to maxillofacial region. Vast analysis and along with proper examination of data to evaluate with final conclusion.Based on our systemic self study we observed this fact that maxillofacial injuries are one of the most frequently encountered injuries which are very often admitted in emergency department. With the revolution of technology in healthcare, today 3D Computed tomography has become the ultimate and primary imaging method because of its significant technical improvement.We concluded that 3D Computed Tomography imaging is very useful for assessing the severity of midface fracture and injury. The reason for 3D Computed Tomography being chosen as imaging choice is just because the 3D image displays the spatial relationships of fracture segments which are in dislocated form and assists surgeons with better graphic display of the actual anatomic presentation which further guides and asists in the management planning and surgical approach in operation Theatre. Hence 3D Computed tomography is the imaging method of choice for an accurate diagnosis which have totally replaced conventional radiography due to its inability to depict the complex anatomical structure of maxillofacial region. This is the reason 3D Computed Tomography is regarded as golden choice in cases of oro-maxillofacial trauma.
颌面部是人体最复杂的骨骼解剖部位。该区域的损伤可分为涉及骨成分的孤立损伤和涉及整个面部骨骼的复杂颌面损伤。颌面部损伤成像技术的目的是在空间平面上精确评估软组织和硬组织的解剖元素的位置。最古老的颌面损伤成像方法是经典的x射线。传统方法面临的挑战是无法精确地表示面部骨骼的所有骨骼结构,并且很难以详细的形式访问面部软组织的元素。计算机断层扫描已经取代了传统的x射线,现在是一种非常重要的成像工具,用于非常精确地评估颌面部创伤,它的潜力在于能够检测到骨折的确切数量、位置和程度。通过系统的自我研究,分析颌面部外伤病例的最佳成像技术选择。利用电子数据库检索PubMed、Google Scholar、Web of Science、Clinical Trial Gov、Medline Plus、health line、John Hopkins Medicine等英文出版的文献。本系统的自我研究回顾了先前发表的事实,以确定任何颌面部创伤的理想成像技术选择。大量的分析和适当的数据检查,以评估最终结论。通过系统的自我研究,我们发现颌面部损伤是急诊科最常见的损伤之一。随着医疗保健技术的革命,如今3D计算机断层扫描由于其显著的技术进步,已经成为最终和主要的成像方法。我们的结论是,三维计算机断层成像对评估中面部骨折和损伤的严重程度非常有用。之所以选择3D ct作为影像学选择,是因为3D图像能显示脱位骨折节段的空间关系,有助于外科医生更好地显示实际解剖表现,从而指导和协助手术室的治疗计划和手术入路。因此,三维计算机断层扫描是准确诊断的首选成像方法,由于无法描绘颌面部区域复杂的解剖结构,它已经完全取代了传统的x线摄影。这就是为什么三维计算机断层扫描被认为是口腔颌面创伤病例的黄金选择。

COVID-19 (Coronavirus disease 2019) was declared a “pandemic” by the World Health Organization (WHO) in early March 2020. All over the world extraordinary measures are being adopted to fight the spread of the ongoing outbreak. Under such conditions, people’s knowledge to preventive measures is greatly affected by their awareness of the disease. Aim of the present study was to assess the awareness and knowledge about Covid-19 among non-treating staff in hospitals. The community-based, cross-sectional survey was conducted using a self-developed structured questionnaire and individuals were personally interviewed. A total of 82 individuals were interviewed who included the sterilization workers, cleaners and ward staff. The non-teaching staff included was working in the dental, medical and physiotherapy institute. The result interpretation showed that 95.1% of participants included in the study knew about Covid-19. Awareness was pragmatic among 89% about the precautions to be taken. While, 63.4% agreed on getting formal training from the workplace. Respondents agreed to change the methods and adopt newer techniques to bout with the Covid-19 pandemic. Since its initial outbreak in China in December 2019, the COVID-19 disease has had a cascading effect worldwide. Even though these subjects are not actively involved in patient management, there are high chances of non-clinical staff having patient contact at some point in the healthcare setting and therefore at risk of contracting and spreading the infection.
2020年3月初,世界卫生组织(世卫组织)宣布COVID-19(冠状病毒病2019)为“大流行”。世界各地正在采取非常措施,以防止当前疫情的蔓延。在这种情况下,人们对预防措施的了解程度很大程度上受到疾病意识的影响。本研究的目的是评估医院非治疗人员对Covid-19的认识和知识。以社区为基础的横断面调查采用自行开发的结构化问卷和个人访谈进行。共采访了82人,包括消毒工人、清洁工和病房工作人员。包括在牙科、医疗和理疗研究所工作的非教学人员。结果解释显示,研究中95.1%的参与者知道Covid-19。89%的人对要采取的预防措施有实际的认识。而63.4%的人同意从工作场所接受正规培训。受访者同意改变方法并采用更新的技术来应对Covid-19大流行。自2019年12月在中国首次暴发以来,新冠肺炎在全球范围内产生了连锁反应。尽管这些受试者没有积极参与患者管理,但在医疗保健环境中,非临床工作人员在某些时候与患者接触的可能性很高,因此有感染和传播感染的风险。

Long term edentulism in the maxillary posterior region presents with complications that compromise the quality and quantity of the residual ridge, making the implant placement impossible. Despite of these challenges, prosthetically driven dental implants tend to restore function using various sinus membrane elevation and augmentation techniques. Over the past few years, these techniques have undergone several advancements aiming to overcome the short comings of the conventional techniques and assuring a successful outcome.

Maxillary sinus is the largest among the paranasal sinus which is of surgical clinical and anthropological significance. Classification of maxillary antrum based on shapes and sizes using panoramic radiography have not been developed till date. Different shapes and sizes of maxillary antrum were taken into notice while tracing orthopantomogram. As panoramic radiograph is the most commonly available and feasible technology, a deeper study of this topic felt compelling.: To classify maxillary antrum based on its shape, presence of septa, shape of the floor and presence of recess employing digital panoramic radiographs. A total of 1000 panoramic radiographs available in soft copies in Department of Oral Radiology, Sree Anjaneya Institute of Dental Sciences were analysed for developing this classification. The panoramic radiographs were taken using KODAK 8000 carestream machine with exposure parameters 73kVp, 12mA, 13.9 seconds. The shapes identified included cloudy, rectangle, round, trapezoidal, square, ovoidal, pentagonal, hexagonal. In which cloudy marked the highest and hexagonal the least. Among the maxillary sinuses observed a few showed septations. The sinus floor contours observed comprised scalloped, wavy, curved, straight and v-shaped. Out of which a few showed recess. This is a proposed new classification of maxillary antrum using Panoramic radiograph. From this study, eight distinct shapes of the maxillary sinus were identified, wherein cloudy type was predominant and hexagonal was the least commonest. Only a few had sepatations and recess. Six distinct shapes of floor were identified, of which scalloped marked the highest.
上颌窦是鼻窦中最大的一类,具有外科、临床和人类学意义。基于上颌上颌窦形状和大小的全景x线摄影分类至今尚未发展起来。上颌上颌窦的不同形状和大小在进行骨断层扫描时得到了注意。由于全景x线摄影是最常见和可行的技术,因此对这一主题的深入研究令人信服。采用数字全景x线片,根据上颌上颌窦的形状、有无隔、底的形状和有无隐窝进行分类。Sree Anjaneya牙科科学研究所口腔放射科共1000张全景放射照片的软拷贝进行了分析,以发展这一分类。全景x线照片采用KODAK 8000 carestream相机拍摄,曝光参数为73kVp, 12mA, 13.9秒。识别的形状包括云状、矩形、圆形、梯形、方形、卵形、五边形和六边形。其中多云标记最高,六边形标记最少。上颌窦中,少数出现分隔。观察到的窦状地板轮廓包括扇形、波浪形、弯曲形、直形和v形。其中有几个显示出凹槽。这是一种使用全景x线片对上颌上颌窦的新分类。从本研究中,我们发现上颌窦有八种不同的形状,其中以混浊型为主,六边形最不常见。只有少数班级有课间间隔和课间休息。六种不同形状的地板被识别出来,其中扇形地板是最高的。

: Calcium hydroxide (Ca(OH)2) has been used as a root canal medicament due to its antimicrobial activity and organic tissue dissolution capacity. To, increase the efficiency and success of root canal/endodontics treatment calcium hydroxide has to be removed from the canals walls. This study evaluate and compare four different irrigation system i.e. Conventional Irrigation (plastic 30 gauge needle), Sonic Irrigation ( Endoactivator), Ultrasonic Continuous Irrigation and Negative pressure with Endo Irrigation plus.For carrying out this study we have used 50 extracted premolar roots, preserved in sodium hypochlorite. Then they were randomly allocated five in four groups (n=10) and a control group. Specimen were statistically analysed by Kruskal Wallis test. All Testing was performed at significance level P-values 0.05.

氢氧化钙(Ca(OH)2)因其抗菌活性和有机组织溶解能力而被用作根管药物。为了提高根管治疗的效率和成功率,必须从根管壁上去除氢氧化钙。本研究评估和比较了四种不同的灌溉系统,即常规灌溉(塑料30号针),超声灌溉(内激活器),超声连续灌溉和负压带内藤灌溉+。为了进行这项研究,我们使用了50个提取的前磨牙根,保存在次氯酸钠中。然后将5人随机分为4组(n=10)和对照组。采用Kruskal - Wallis检验对标本进行统计学分析。所有检验均以显著性水平p值0.05进行。分析采用社会科学版(SPSS)17.0 for Windows(SPSS)。美国,芝加哥,IL)。在我们目前的研究中,我们发现没有一种技术可以完全去除根管中的Ca(OH)2。但超声灌洗系统(内激活器)在去除氢氧化钙方面有一些潜在的好处。

Eagle’s syndrome is a condition associated with the elongation of the styloid process or calcification of the stylohyoid ligament, clinically characterised by throat and neck pain, radiating into the ear. A styloid process is considered elongated or abnormal when it exceeds a normal length of 25-27 mm. However, elongation of the ossified styloid ligament is insufficient for diagnosing Eagle’s syndrome. Instead, a constellation of symptoms in history, as mentioned above, and physical and radiographic examinations contribute to diagnosis. In this report, we describe the case of a 71-year-old man who presented with long standing orofacial pain due to unilateral elongated styloid process on the right side.
鹰氏综合征是一种与茎突延长或茎突舌骨韧带钙化相关的疾病,临床表现为喉咙和颈部疼痛,并向耳部放射。当茎突的长度超过正常的25-27毫米时,被认为是拉长或异常。然而,骨化茎突韧带的伸长不足以诊断Eagle综合征。相反,病史中的一系列症状(如上所述)以及体格和放射检查有助于诊断。在这个报告中,我们描述的情况下,71岁的男子谁提出了长期站立口面部疼痛,由于单侧茎突延长右侧。
