Apical periodontitis, a chronic inflammatory lesion of the periradicular tissue, is caused by etiological agents of endodontic origin. It is considered as a potent communication between microbiological factors and defense system of the host at the interface of periodontal ligament and infected radicular pulp. Endodontic treatment failure is often characterized by the existence of post-treatment apical periodontitis, which may be persistent, recurrent or emergent. The major etiology of persisting disease is an intraradicular infection, however in certain cases a secondary intraradicular infection due to factors like leakage from the coronal part of the tooth or an extraradicular infection may be the cause of failure.
根尖牙周炎是根周组织的一种慢性炎症性病变,是由根管起源的病原体引起的。它被认为是牙周膜与感染根髓交界面微生物因子与宿主防御系统之间的有效沟通。根管治疗失败通常以治疗后出现根尖牙周炎为特征,可能是持续性、复发性或突发性的。顽固性疾病的主要病因是根内感染,但在某些情况下,由于牙齿冠状部分渗漏或根外感染等因素引起的继发性根内感染可能是失败的原因。

Periodontitis is an inflammatory disease which results by the interaction between bacteria leading to inflammation and destruction of the connective tissue attachment apparatus. Flap surgeries are most frequently employed treatment modality for deep periodontal pockets. Over the decades, many suture materials like silk and nylonare being used for the approximation of the flaps. In the present scenario of periodontal advancements, fibrin glue manifests to be a great alternative to flap approximation with better clinical and histological results.This randomized clinico-histological study aims to compare the healing of modified flap operation when approximated with Silk suture and N-butyl cyanoacrylate bioadhesive.Thirty patients were recruited in this clinico-histological study. In Group A, surgical site was approximated by 3-0 black braided silk sutures (@TRUSILK) and in Group B, N-butyl cyanoacrylate bioadhesive (@EPICLOS) was used by driplets for flap approximation. Patients were recalled for removal of sutures and any cyanoacrylate present after 1 week of surgery. All the parameters (clinical and histological) were taken at baseline and at 7 day.On intra and inter group comparison all the clinical parameters i.e., Gingival index (GI), Papillary Marginal Attachment (PMA) Index, Turesky-Gilmore-Glickman modification of Quigley Hein Plaque Index (TQHPI), Wound healing index (WHI) and histological parameters i.e., inflammatory cells and vascularity shows significant reduction at 7 day in group B (N-butyl-cyanoacrylate).N-butyl-cyanoacrylate (Group B) is more effective in reducing the clinical and histological parameters than Silk sutures (Group A).
牙周炎是一种炎症性疾病,由细菌之间的相互作用导致炎症和结缔组织附着体的破坏。皮瓣手术是深牙周袋最常用的治疗方式。几十年来,许多缝合材料,如丝绸和尼龙被用于近似皮瓣。在目前牙周进展的情况下,纤维蛋白胶是一种很好的替代皮瓣近似,具有更好的临床和组织学结果。本随机临床组织学研究的目的是比较改良皮瓣手术时,接近丝缝合和氰基丙烯酸酯正丁酯生物胶愈合。在这项临床组织学研究中招募了30名患者。A组采用3-0条黑色编织丝缝合线(@TRUSILK)缝合手术部位,B组采用滴剂滴入的氰基丙烯酸酯正丁酯生物胶粘剂(@EPICLOS)缝合皮瓣。患者在手术1周后被召回以去除缝合线和任何氰基丙烯酸酯。在基线和第7天采集所有参数(临床和组织学)。组内组间比较,龈指数(GI)、乳头边缘附着指数(PMA)、Turesky-Gilmore-Glickman修饰的Quigley Hein斑块指数(TQHPI)、创面愈合指数(WHI)及组织学参数(炎症细胞和血管密度)均在第7天显著降低。正丁基氰基丙烯酸酯(B组)在降低临床和组织学参数方面比丝线(A组)更有效。

The ongoing global COVID-19 pandemic has infected hundreds of millions of people over the world, imposing a tremendous burden on the global healthcare system including the dental community. COVID-19 vaccines are currently the best defense against the rapidly evolving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there are emerging concerns about vaccine breakthrough infections. This study has been done to assess the COVID- 19 breakthrough infection among the vaccinated Dental student community of North Kerala and also evaluate and compare the severity of COVID-19 infection among vaccinated and non-vaccinated individuals. A survey was performed within the Dental student community which included BDS students, House surgeons and Post graduates by means of a questionnaire administered online via Google forms that consisted of demographic information and questions to assess severity of the COVID-19 breakthrough infection. The data were analyzed using the SPSS version 26 software. Result was presented in frequencies, percentages and charts showing the interrelatedness of the variables examined. Among the 714 respondents there were 11.9% males and 88.1% females. Majority of the study subjects reported to have completed two doses of Covid vaccine, while 11.5% had taken only a single dose and 1% had not been vaccinated at all. Around 13% of subjects gave history of being Covid positive before vaccination and (14.7%) got infected even after vaccination.New Covid variants are being evolved continuously, thereby increasing the chance for transmissibility and evasion of the host immune response. This could be the reason for the 14.7% breakthrough infections reported in our study. Therefore, the need for future studies to recognize factors leading to inadequate vaccine response in those with breakthrough infections and ways to mitigate them is highlighted.
新型冠状病毒肺炎(COVID-19)全球大流行在全球范围内感染了数亿人,给包括牙科界在内的全球医疗保健系统带来了巨大的负担。COVID-19疫苗是目前对抗迅速演变的严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)的最佳防御手段。然而,对疫苗突破感染的担忧正在出现。本研究旨在评估北喀拉拉邦接种疫苗的牙科学生社区中COVID-19的突破性感染情况,并评估和比较接种疫苗和未接种疫苗的个体中COVID-19感染的严重程度。在包括BDS学生、住院外科医生和研究生在内的牙科学生社区中进行了一项调查,通过谷歌表格在线进行问卷调查,包括人口统计信息和评估COVID-19突破性感染严重程度的问题。采用SPSS 26版软件对数据进行分析。结果以频率,百分比和图表的形式呈现,显示了所检查变量的相互关系。在714名受访者中,男性占11.9%,女性占88.1%。大多数研究对象报告说已经接种了两剂新冠病毒疫苗,而11.5%的人只接种了一剂疫苗,1%的人根本没有接种疫苗。约13%的受试者在接种疫苗前有Covid阳性史,(14.7%)甚至在接种疫苗后仍被感染。新的冠状病毒变体正在不断进化,从而增加了传播和逃避宿主免疫反应的机会。这可能是我们研究中报告的14.7%突破性感染的原因。因此,强调需要进行未来的研究,以识别导致突破性感染患者疫苗反应不足的因素以及减轻这些因素的方法。

In December 2019, a novel infection called Corona virus disease (COVID-19) was first detected in Wuhan, China; caused by severe acute respiratory syndrome Corona virus 2 (SARS-CoV-2).On 11th March,2020, the World Health Organization declared COVID-19 infection a pandemic. Since then the scientific community around the world is trying to decipher this infection to control it better. We have been successful in formulating the vaccine against it in record time, but during this course, it has taken a huge toll of human lives leaving behind people who got infected with various side effects of the infection. In the absence of any definitive treatment, many alternative modes of management systems have appeared. Various herbal agents appear to have a potential role in prevention and management of this infection. In the limited time so far, several studies have been conducted which have shown positive results but also highlights their potential drawbacks with insufficient scientific evidence. This review describes the potential role of common herbal agents as possible means of management of this infection and the need of further research in this direction where these traditional and relatively safe methods could be integrated in the management schemes of various chronic infections and diseases.
2019年12月,在中国武汉首次发现了一种名为冠状病毒病(COVID-19)的新型感染;由严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)引起。2020年3月11日,世界卫生组织宣布COVID-19感染为大流行。从那时起,世界各地的科学界都在试图破译这种感染,以更好地控制它。我们在创纪录的时间内成功地研制出了针对它的疫苗,但在这一过程中,它造成了巨大的生命损失,留下了感染了这种感染的各种副作用的人。在没有任何确定的治疗方法的情况下,出现了许多可供选择的管理制度模式。各种草药似乎在预防和管理这种感染方面具有潜在的作用。到目前为止,在有限的时间内,已经进行了几项研究,这些研究显示了积极的结果,但也突出了其潜在的缺点,科学证据不足。这篇综述描述了常见的草药作为治疗这种感染的可能手段的潜在作用,以及在这个方向上进一步研究的必要性,这些传统的和相对安全的方法可以整合到各种慢性感染和疾病的治疗方案中。

Facial space infection is the most common infection, which is considered as the life­-threatening problem. It occurs due to the poor oral hygiene and other etiological factors such as tooth infection, decreased immunity. The main path of the spread of the infections is the odontogenic path. The patients having the habit of smoking, tobacco use, chewing areca nuts etc. are at the high risk of having odontogenic infection. So the odontogenic infections are considered as the origin of space infections. Out of which the submandibular space infections is the most common. Mostly it occurs due to the periapical infection and pericoronitis around the mandibular third molar. In this report we have described 38 years old female with the submandibular space infection which appeared 10 days after visiting a local dentist. The clinical characterstics were seen and the management of submandibular space infection was done.
面部空间感染是最常见的感染,被认为是危及生命的问题。它的发生是由于口腔卫生不良和其他病因如牙齿感染,免疫力下降。感染传播的主要途径是牙源性途径。有吸烟、吸烟、嚼槟榔等习惯的患者是患牙源性感染的高危人群。因此,牙源性感染被认为是空间感染的起源。其中,下颌间隙感染最为常见。它主要是由于下颌第三磨牙周围的根尖周感染和冠周炎。在这个报告中,我们描述了38岁的女性与下颌骨间隙感染,出现了10天后,看了当地的牙医。观察其临床特点,并对其进行处理。

The aim of this study was to compare the effect of recycling orthodontic metal brackets by sandblasting with aluminum oxide particles of different sizes and by laser blow method after first and second rebonding /recycling. 120 human premolars extracted for orthodontic purpose were randomly divided into four groups. 40 MBT prescription Orthodontic metallic brackets were bonded on the buccal surface of the samples. Brackets were recycled by sandblasting with 3 different particles size and laser. Debonding of all brackets was performed using a universal testing machine and shear bond strength was determined. Brackets were examined under Field emission scanning electron microscope from each group at each level to compare the surface characteristic of new and rebonded brackets. Data were analyzed with paired test, ANOVA, and post hoc tests.The shear bond strength of group I (sandblasted with 25µm alumina) was significantly higher at the end of 1st recycling compared to group II(50 µm) and III(100 µm) but it was comparable to group IV(laser) at the end of 1st recycling. Group IV showed clinically significant higher shear bond strength compared to group II and III after 1st and 2nd recycling. The shear bond strength for group II and III (sandblasted with 50 and 110µm alumina) was significantly much lower after 2nd recycling as compared to new i.e., Control (p value<0.001⁎⁎⁎).25µm alumina sandblasting and Er-YAG laser blow method obtained better results after three successive recycling. Overall sandblasting emerged as the best method to recycle the orthodontic brackets.
本研究的目的是比较不同大小的氧化铝颗粒喷砂和激光吹砂法在一次和二次再粘/回收后对正畸金属托槽的回收效果。将120颗拔除用于正畸的人前磨牙随机分为4组。将40个MBT处方正畸金属托槽粘接在口腔表面。支架采用三种不同粒度的激光喷砂回收。使用万能试验机对所有支架进行脱粘,并测定剪切粘接强度。在场发射扫描电子显微镜下对每一组、每一层的支架进行检查,比较新支架和再粘合支架的表面特征。数据分析采用配对检验、方差分析和事后检验。在第一次回收结束时,I组(喷砂25µm氧化铝)的剪切结合强度明显高于II组(50µm)和III组(100µm),但在第一次回收结束时与IV组(激光)相当。第1次和第2次循环后,IV组的剪切粘接强度明显高于II组和III组。第II组和第III组(用50和110µm氧化铝喷砂)的剪切强度在第二次循环后明显低于新组,即对照组(p值<0.001)。25µm氧化铝喷砂法和Er-YAG激光吹砂法连续三次回收后效果较好。整体喷砂是修复正畸托槽的最佳方法。

In the present era, esthetics has become an important dimension in dental practice as parents and children are equally self-conscious of their appearance. Children now desire to possess an aesthetically pleasing smile. Harmonizing an esthetic smile integrates facial and dental components. Since the scientific data on pediatric esthetics are limited, the aim of the study was to evaluate esthetic parameters of the face and components of smile in children with deciduous dentition.: After fulfilling inclusion criteria, 3 sets of facial photographs of 100 children were obtained, comprising of frontal at rest, frontal smile and profile at rest images under standardised photographic technique. Linear measurements of facial and dental parameters were assessed with the help of Adobe photoshop and static norms were obtained by taking the average value. Subjective evaluation was performed by a group of professionals using Q-sort technique to list the attractive features in children.Static norms were obtained for facial and dental parameters. Attractive children showed decreased facial height, anterior lower facial height, vermilion height and bigonial width. They also displayed decreased smile index and buccal corridor ratio along with parallel smile arc and more than 3/4th of crown height visibility during smiling. Attractive children presented facial and dental parameters variable from normative values. : The study results can be utilised during restorative and prosthetic rehabilitation among children to improve esthetics.
在当今时代,美学已经成为牙科实践的一个重要维度,因为父母和孩子同样对自己的外表有自我意识。现在的孩子们渴望拥有一个美丽的微笑。和谐的美学微笑整合了面部和牙齿的组成部分。由于儿童美学方面的科学资料有限,本研究的目的是评估乳牙列儿童面部和微笑成分的美学参数。:在满足纳入标准后,获得100名儿童的3组面部照片,包括标准化摄影技术下的静止正面、微笑正面和静止侧面图像。利用Adobe photoshop软件对面部和牙齿参数进行线性测量,取平均值得到静态规范。主观评价是由一组专业人员使用q -排序技术列出儿童的吸引力特征。获得面部和牙齿参数的静态规范。有吸引力的儿童面部高度、前下面部高度、朱红色高度和双侧宽度均下降。在微笑时,他们的微笑指数和颊走廊比例以及平行微笑弧度都有所下降,冠高可见度超过3/4。有吸引力的儿童的面部和牙齿参数从规范值变化。研究结果可用于儿童的修复和义肢康复,以改善美学。

Since the scientific data on pediatric esthetics are limited, the aim of the study was to evaluate esthetic parameters of the face and components of smile in children with deciduous dentition.: After fulfilling inclusion criteria, 3 sets of facial photographs of 100 children were obtained, comprising of frontal at rest, frontal smile and profile at rest images under standardised photographic technique. Linear measurements of facial and dental parameters were assessed with the help of Adobe photoshop and static norms were obtained by taking the average value. Subjective evaluation was performed by a group of professionals using Q-sort technique to list the attractive features in children.Static norms were obtained for facial and dental parameters. Attractive children showed decreased facial height, anterior lower facial height, vermilion height and bigonial width. They also displayed decreased smile index and buccal corridor ratio along with parallel smile arc and more than 3/4th of crown height visibility during smiling. Attractive children presented facial and dental parameters variable from normative values. : The study results can be utilised during restorative and prosthetic rehabilitation among children to improve esthetics.","PeriodicalId":91704,"journal":{"name":"International journal of dentistry and oral health","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87748756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Autism is a disorder that is increasing many folds in incidence and is now considered an epidemic. There are no objective ways to confirm the disorder. Diagnosis is formed subjectively, supported by the perceived behavior of the subject. Therapeutic interventions have better results when started early in life in autism spectrum disorder, yet diagnosis often remains delayed, partly because it mainly relied on identifying abnormal behaviors which will be delayed or not emerge until the disorder is well established. Even so, many promising areas of research have disclosed abnormal biological processes that are related to ASD. Biomarkers that are identified on children who are at risk during the pre-symptomatic period can assist with early diagnosis, confirm behavioral observations, stratify patients into subgroups, and predict therapeutic response. Knowledge of the numerous biomarkers of ASD is important as it can go a long way in the early diagnosis of the condition and some may predict response to specific treatments. Through this review, we intend to give an insight into various biomarkers of ASD that have to date been established for its diagnosis and intervention. It's likely that biomarkers should be combined with other parameters to be effective to identify ASD early and guide proper therapeutic interventions.
自闭症是一种发病率增加了许多倍的疾病,现在被认为是一种流行病。没有客观的方法来确认这种疾病。诊断是主观形成的,由主体的感知行为支持。如果在自闭症谱系障碍患者的生命早期就开始进行治疗干预,效果会更好,但诊断往往仍然延迟,部分原因是它主要依赖于识别异常行为,这些异常行为将被延迟或在疾病完全确定之前不会出现。即便如此,许多有前景的研究领域已经揭示了与ASD相关的异常生物学过程。在症状前有风险的儿童身上识别出的生物标志物可以帮助早期诊断,确认行为观察,将患者分为亚组,并预测治疗反应。了解ASD的众多生物标志物是很重要的,因为它可以在病情的早期诊断中走很长的路,有些可以预测对特定治疗的反应。通过这篇综述,我们打算深入了解迄今为止已经建立的用于ASD诊断和干预的各种生物标志物。很可能生物标志物应该与其他参数相结合,以有效地早期识别ASD并指导适当的治疗干预。

The present study compares the effectiveness of inferior alveolar nerve block and infiltration in the extraction of posterior mandibular teeth. 90 patients were divided into two groups. Group 1 included 45 patients and for each tooth, two injections (0.6 ml out of 1.8 ml of 2% lidocaine from one dental cartridge with 1:80000 adrenaline) were administered, one Local Anesthetic injection was given parallel to the long axis of the tooth in the depth of buccal sulcus with short needle and dental syringe. The second injection was delivered to the lingual vestibule of the mouth's floor to anaesthetize the soft and hard lingual tissue with short needle and dental syringe, whereas Group 2 included 45 patients and were given Inferior Alveolar Nerve Block (1.5 ml of 2% Lidocaine) and Long Buccal nerve Infiltration (0.3ml of 2% Lidocaine). In our study, we found 78% patients was pain free and 22% was feeling pain during tooth extraction in patients who were given infiltration, whereas patients in which Inferior alveolar nerve block was given, 89% patients was pain free and 11% were feeling pain during tooth extraction. 94% of males and 85% of females experienced no pain, whereas 6% of males and 15% of females felt pain during the extraction. The present study suggests that Infiltration can be used as an alternative approach to inferior alveolar nerve block during the extraction of Mandibular posterior teeth.
本研究比较下牙槽神经阻滞和浸润法在下颌后牙拔除中的效果。90例患者分为两组。第一组45例患者,每颗牙注射2次局麻(从1个牙盒中取2%利多卡因1.8 ml,肾上腺素1:8000),用短针和牙注射器平行于牙长轴在颊沟深处注射1次局麻。第2组45例患者采用下牙槽神经阻滞术(2%利多卡因1.5 ml)和颊长神经浸润术(2%利多卡因0.3ml),第2组采用口腔底舌前庭用短针和牙科注射器麻醉舌软硬组织。在我们的研究中,我们发现浸润组拔牙时78%的患者无疼痛感,22%的患者有疼痛感,而下牙槽神经阻滞组拔牙时89%的患者无疼痛感,11%的患者有疼痛感。94%的男性和85%的女性没有感到疼痛,而6%的男性和15%的女性在拔牙过程中感到疼痛。本研究提示浸润法可作为下颌后牙拔除时下牙槽神经阻滞的替代方法。
