Background: Fracture incidences are more common in teeth with endodontic therapy and hence endodontic therapy should aim toward the reinforcement of such teeth by placing various restorative materials. Aims: Comparative evaluation of different intraorifice barrier material on strengthening the fracture resistance of teeth requiring endodontic therapy. Methods: Sixty extracted human mandibular premolars with one root were divided into four groups (n = 15); Group 1- Light cured Glass ionomer cement, Group 2 - Nanohybrid composite (NHC), Group 3 - High copper amalgam, Group 4-Control. Decoronation of specimens was done to a standardized length of 14 mm and was instrumented up to International Organization for Standardization (ISO) #30 size master apical file. Gutta percha was used to carry out the obturation by the cold lateral compaction technique. With the exception of the control group, elimination of 3 mm obturation from the coronal portion was done and intraorifice barrier materials were placed. Universal Testing Machine was used for testing fracture resistance. Statistical Analysis: Analysis of variance was applied to analyze the data obtained and pairwise comparison was done by post hoc tukey's test (P < 0.05). Results: Better resistance to fracture incidence was seen with NHCs. Control group presented the least values. Conclusion: On placement of intraorifice barrier materials in teeth with endodontic therapy, there was a reduction in fracture incidence.
背景:骨折发生率在接受牙髓治疗的牙齿中更为常见,因此牙髓治疗应通过放置各种修复材料来加固这些牙齿。目的:比较评价不同牙缝内屏障材料在增强需要根管治疗的牙齿抗折性方面的作用。方法:将60颗单根拔除的下颌前磨牙分为4组(n=15);第1组-光固化玻璃离聚物水泥,第2组-纳米杂化复合材料(NHC),第3组-高铜汞合金,第4组对照。将标本去冠状动脉化至14mm的标准化长度,并按照国际标准化组织(ISO)#30尺寸的主心尖锉进行仪器化。采用牙胶冷侧压技术进行充填。除对照组外,从冠状部分消除3 mm的闭塞,并放置验证内屏障材料。万能试验机用于测试断裂阻力。统计分析:采用方差分析法对所获得的数据进行分析,并通过post-hoc tukey检验进行配对比较(P<0.05)。结果:NHCs对骨折发生率有更好的抵抗力。对照组的数值最低。结论:在根管治疗的情况下,在牙齿中放置牙缝内屏障材料可以降低骨折发生率。

Severe early childhood caries (S-ECC) is a health concern which can lead to reduced overall quality of life. In most cases, due to the extent of rehabilitation required and difficulty in obtaining cooperation of the patient due to their age necessitates management under general anesthesia (GA). However, the COVID-19 pandemic limited dental treatment to emergency procedures only. The objective of this study was to report two cases of emergency management of S-ECC, under GA, emphasizing on the protocols and procedures required to be followed to safely deliver treatment in the background of the pandemic. Two children aged 3.5 years and a 5 years, respectively, were brought to the department by their parents due to severe pain, difficulty in chewing, and disturbed sleep. They were taken up as emergency cases for rehabilitation to alleviate pain and restore function. Protocols and procedures to prevent transmission of COVID-19 during treatment were followed stringently. In emergency management to rehabilitate patients suffering from S-ECC, care should be taken to follow all protocols instituted to prevent transmission of COVID-19 infection. This is highlighted in the oral cavity due to an increased chance of transmission during aerosol-generating procedures.
严重的儿童早期龋齿(S-ECC)是一种健康问题,可导致整体生活质量下降。在大多数情况下,由于需要康复的程度以及患者年龄的原因难以获得合作,需要在全身麻醉(GA)下进行管理。然而,新冠肺炎大流行将牙科治疗仅限于紧急程序。本研究的目的是报告两例在GA下的S-ECC紧急管理病例,强调在大流行背景下安全提供治疗所需遵循的协议和程序。两名分别为3.5岁和5岁的儿童因剧烈疼痛、咀嚼困难和睡眠障碍被父母带到该科。他们被作为紧急病例接受康复治疗,以减轻疼痛并恢复功能。严格遵守治疗期间预防新冠肺炎传播的协议和程序。在康复S-ECC患者的应急管理中,应注意遵守为防止新冠肺炎感染传播而制定的所有协议。由于气溶胶产生过程中传播的机会增加,这在口腔中尤为突出。

Periodontitis is a microbial disease of tooth-supporting tissues that results in progressive destruction of surrounding soft and hard tissues with eventual loss of tooth or tooth mobility. A comprehensive literature search was performed by using the keywords: periodontitis, periodontal disease, combined with the word genes, mutation, or polymorphism. Gene polymorphism studies with a reported genotype frequency in chronic periodontitis (CP) and aggressive periodontitis (AgP) patients were searched and reviewed. There has been a growing evidence of polymorphisms in the interleukin (IL)-1, IL-4, IL-6, IL-10, IL-12, and tumor necrosis factor-alpha with CP and AgP in certain populations. However, carriage rates of the rare (R) allele of any polymorphism varied considerably among studies, and most of the studies appeared underpowered and did not correlate for other risk factors, hence furthermore researches are required including large sample size, different races, genotypes, and other risk factors which were found to be influential in expression and severity of CP and AgP to get a more comprehensive insight into the contribution of IL gene polymorphisms in CP and AgP.
牙周炎是一种牙齿支持组织的微生物疾病,会导致周围软组织和硬组织的逐渐破坏,最终导致牙齿或牙齿丧失活动能力。使用关键词进行全面的文献检索:牙周炎、牙周病,结合基因、突变或多态性。对慢性牙周炎(CP)和侵袭性牙周炎(AgP)患者基因型频率的基因多态性研究进行了检索和综述。越来越多的证据表明,在某些人群中,白细胞介素(IL)-1、IL-4、IL-6、IL-10、IL-12和肿瘤坏死因子α与CP和AgP存在多态性。然而,任何多态性的罕见(R)等位基因的携带率在研究中都有很大差异,而且大多数研究似乎动力不足,与其他风险因素无关,因此需要进一步的研究,包括大样本量、不同种族、基因型,以及其他对CP和AgP的表达和严重程度有影响的危险因素,以更全面地了解IL基因多态性对CP和AgP的贡献。

The legendary Greek philosopher, Aristotle once said that “Man is by nature a social animal.” Biological transmission of any disease is linked to the social contact of human beings. Respiratory infections are the best example of it. Pandemics of respiratory viral illnesses in history have taught a lesson of simple measures to protect ourselves by using face masks. Since the last nine centuries, scientists have struggled to come up with the masks giving 95%–99% of protection against respiratory pathogens. Through this article, we aim to review the evolution of the mask through times, with the objective of finding its effectiveness in preventing infections and also its role as a source of infection. Various online databases were searched to find articles that provided description of evolution of the mask.
希腊传奇哲学家亚里士多德曾说过:“人天生就是一种社会动物。”任何疾病的生物传播都与人类的社会接触有关。呼吸道感染就是最好的例子。历史上呼吸道病毒性疾病的流行给我们上了一堂通过使用口罩保护自己的简单措施的课。自过去九个世纪以来,科学家们一直在努力研制出能够对呼吸道病原体提供95%-99%保护的口罩。通过这篇文章,我们旨在回顾口罩的时代演变,目的是发现它在预防感染方面的有效性,以及它作为感染源的作用。搜索了各种在线数据库,以找到提供口罩进化描述的文章。

Introduction: Dermoid and epidermoid cysts commonly termed as “Dermoids” are known to be developmental benign swellings that possibly occur as a result of traumatic implantation of epithelium or entrapment of epithelial remnants during embryonic fusion. The occurrence is rare (about 7%) in the head-and-neck region and they represent <1.6% of all cysts of the oral cavity. Patients and Methods: A retrospective study was done on 12 histopathologically proven cases of epidermoid and dermoid cysts of the maxillofacial region that were treated in Shyam Shah Medical College, Rewa, Madhya Pradesh, India, from January 2013 to December 2019. The cases were evaluated for clinical presentation, demographic characteristics, and treatment performed. Results: Out of a total of 12 cases that were included in this study, 10 cases were diagnosed as epidermoid and 2 cases as true dermoid cysts. The mean age of occurrence was 31.66 ± 9.97 years. Male predominance was seen with a male-to-female ratio of 1.4:1. The floor of the mouth was the most commonly involved site in ten (83.34%) cases. Sublingual cysts were seen in five (41.67%) cases, combined sublingual–submandibular involvement in three (25%) cases, and midline floor of the mouth cyst in two (16.67%) cases. All the cases were treated by surgical enucleation, and no recurrence or malignant transformation was reported in any case at a minimum follow-up of 2 years. Conclusion: Based on the findings of this retrospective study, it is suggested that these lesions are very rare in the maxillofacial region and pose a diagnostic challenge. However, fine-needle aspiration cytology, ultrasound imaging, computerized tomography, and magnetic resonance imaging techniques can be relied upon for precise treatment planning. Surgical enucleation of these lesions is the preferred treatment modality.
引言:通常称为“Dermoid”的Dermoid和表皮样囊肿是一种发育性良性肿胀,可能是由于胚胎融合过程中上皮的创伤性植入或上皮残留的包埋而发生的。这种情况在头颈部很少见(约7%),占口腔所有囊肿的1.6%以下。患者和方法:对2013年1月至2019年12月在印度中央邦雷瓦Shyam Shah医学院接受治疗的12例经组织病理学证实的颌面部表皮样囊肿和皮样囊肿进行回顾性研究。对这些病例的临床表现、人口统计学特征和治疗进行评估。结果:在纳入本研究的12例病例中,10例诊断为表皮样囊肿,2例诊断为真皮样囊肿。平均发病年龄为31.66±9.97岁。男性占主导地位,男女比例为1.4:1。在10例(83.34%)病例中,口腔底部是最常见的受累部位。舌下囊肿5例(41.67%),舌下-下颌联合受累3例(25%),口腔中线底囊肿2例(16.67%)。所有病例均通过手术摘除进行治疗,在至少2年的随访中,任何病例均未报告复发或恶性转化。结论:根据这项回顾性研究的结果,这些病变在颌面部非常罕见,对诊断提出了挑战。然而,细针抽吸细胞学、超声成像、计算机断层扫描和磁共振成像技术可以用于精确的治疗计划。手术摘除这些病变是首选的治疗方式。

Subcutaneous emphysema (SE) is a rare but possible complication of dental treatment resulting from the usage of high-speed air-driven instruments and introduction of irrigating solutions like hydrogen peroxide into soft tissues. Two case reports are described here, namely (a) drying of root canals using a three-way syringe by “Venturi” technique and (b) accidental injection of hydrogen peroxide instead of local anesthesia in an infiltration technique. A review of the literature is done wherein a search for terms such as pneumomediastinum, mediastinitis, embolism, or extensive SE (ESC) from 1965 to 2020 using the PubMed search engine was done and the results were tabulated. Since the number of cases and complications reported are on the rise,data regarding diagnosis, investigations, and a management protocol with an emphasis on prevention have been elaborated. Methods such as reductive manipulation or “counter incision,” as incited from medical literature, have been suggested to reduce morbidity and mortality. In both of the case reports, subcutaneous cervicofacial emphysema resolved briefly due to the effectual reduction maneuver implemented promptly.
皮下肺气肿(SE)是一种罕见但可能的牙科治疗并发症,其原因是使用高速气动器械和将过氧化氢等冲洗溶液引入软组织。这里描述了两个病例报告,即(a)使用“文丘里”技术使用三向注射器干燥根管和(b)在浸润技术中意外注射过氧化氢而不是局部麻醉。通过PubMed搜索引擎检索1965 - 2020年间的文献,如纵隔气肿、纵隔炎、栓塞或广泛SE (ESC),并将结果制成表格。由于报告的病例和并发症数量在上升,有关诊断、调查和以预防为重点的管理方案的数据已得到详细阐述。从医学文献中引申的一些方法,如复位操作或“反切口”,已被建议用于降低发病率和死亡率。在这两个病例报告中,由于及时实施了有效的复位操作,皮下颈面肺气肿得到了短暂的解决。

Background: Dental fear and anxiety remains the most common emotions experienced by the child who visit the pediatric dentist. The success of pedodontics is determined by the odontologist's capability to gain the confidence and maintain the cooperation of the child. Objective/Aim: The aim of the study was to assess the behavior and anxiety levels of school-going children in a dental setting using a Miniature Pediatric Dental Office Model during the first dental visit of the child. Study Design: This cross-sectional research was carried out in a dental institute in the department of pediatrics and preventive dentistry. The study protocol was explained to the parents of 3–9-year-old children. Demographics were elicited from the parents and their correlation with the placement of the doll in the pediatric dental office model and a modified Frankl's behavior rating scale was used to assess the child's behavior. Results: Of 84 participants, 47 children were under the age of 6 years and 37 children were ≥6 years of age. In the doll placement test, the majority (36.9%) of the children preferred pattern 2 (the child is on the chair, the dentist is inside the operatory, the mother is inside the operatory, and the father is outside the operatory) in the doll placement test, and the least (8.3%) preferred pattern 1 (the child is on the chair, the dentist is inside the operatory, the father is inside the operatory, the mother is outside the operatory). Thirty-four percent children up to the age of 6 years exhibited a mix of negative-positive behavior, and 43.2% of children aged 6 years showed a positive behavior according to the modified Frankl's rating scale. Conclusion: The doll placement test using a miniature pediatric office aided us in determining the child's anxiety level during their first dental visit. To achieve emotional support and avoid the impact of traumatic separation, especially in younger children, our study showed that mothers should be present in the dental office to remove behavior-related problems.
背景:牙科恐惧和焦虑仍然是去看儿科牙医的孩子最常见的情绪。儿童牙科的成功取决于牙科医生获得孩子信心和保持合作的能力。目的/目的:本研究的目的是在儿童第一次牙科就诊期间,使用小型儿科牙科办公室模型评估在牙科环境中上学儿童的行为和焦虑水平。研究设计:这项横断面研究是在儿科和预防牙科的一个牙科研究所进行的。研究方案向3至9岁儿童的父母进行了解释。从父母那里获得人口统计数据,以及他们与儿童牙科办公室模型中玩偶放置的相关性,并使用改良的Frankl行为评定量表来评估孩子的行为。结果:在84名参与者中,47名儿童年龄在6岁以下,37名儿童年龄≥6岁。在玩偶放置测试中,大多数(36.9%)儿童在玩偶放置试验中更喜欢模式2(孩子在椅子上,牙医在手术室里,母亲在手术室里面,父亲在手术室外面),以及最少(8.3%)的首选模式1(孩子在椅子上,牙医在手术室里,父亲在手术室,母亲在手术室外)。根据改良的Frankl评分量表,34%的6岁以下儿童表现出消极-积极的混合行为,43.2%的6岁儿童表现出积极的行为。结论:使用小型儿科办公室进行的玩偶放置测试有助于我们确定孩子第一次牙科就诊时的焦虑水平。为了获得情感支持,避免创伤分离的影响,尤其是在年幼的孩子身上,我们的研究表明,母亲应该出现在牙科诊所,以消除与行为相关的问题。

The success of pedodontics is determined by the odontologist's capability to gain the confidence and maintain the cooperation of the child. Objective/Aim: The aim of the study was to assess the behavior and anxiety levels of school-going children in a dental setting using a Miniature Pediatric Dental Office Model during the first dental visit of the child. Study Design: This cross-sectional research was carried out in a dental institute in the department of pediatrics and preventive dentistry. The study protocol was explained to the parents of 3–9-year-old children. Demographics were elicited from the parents and their correlation with the placement of the doll in the pediatric dental office model and a modified Frankl's behavior rating scale was used to assess the child's behavior. Results: Of 84 participants, 47 children were under the age of 6 years and 37 children were ≥6 years of age. In the doll placement test, the majority (36.9%) of the children preferred pattern 2 (the child is on the chair, the dentist is inside the operatory, the mother is inside the operatory, and the father is outside the operatory) in the doll placement test, and the least (8.3%) preferred pattern 1 (the child is on the chair, the dentist is inside the operatory, the father is inside the operatory, the mother is outside the operatory). Thirty-four percent children up to the age of 6 years exhibited a mix of negative-positive behavior, and 43.2% of children aged 6 years showed a positive behavior according to the modified Frankl's rating scale.

Background: The change in food consumption patterns with greater reliance on junk and processed foods is more often related to lifestyle disorders nowadays. Dental health status is a clear indicator of lifestyle choices as well as major changes in the lifestyle. Aims and Objectives: The aim of the present study was to assess the dental health status of individuals of Shimla (Himachal Pradesh, India) on the basis of their primary dental check-up and the interview-based data. Materials and Methods: A total of 301 individuals (152 males and 149 females) were examined for dental caries, dental plaque, and periodontal diseases among them followed by an interview session inquiring about their dietary intake and lifestyle patterns. The frequency distribution for each state was calculated for each tooth type, and statistical analyses were done. Results: The number of decayed, missing, and filled teeth of each subject resulted in the calculation of average decayed-missing-filled teeth index as 1.5182. The calculated significant caries index and plaque index were found as 3.06 and 1.2872, respectively. The maxillary teeth (59.2% and 43.62% in males and females, respectively) were more affected than the mandibular teeth (37.5% and 47.5% in males and females, respectively). The survey showed that the most affected teeth by caries were first premolars and first molars (22.36% of males and 30.87% of females showed caries in their first premolars; 25% of males and 15.43% of females showed caries in their first molars). Conclusion: The overall dental health status revealed that females had more deteriorated dental health conditions than males, though the difference in the frequencies was not statistically significant. Dietary survey has revealed that their diet includes a high amount of sugar content along with carbonated drinks and junk food.
背景:食品消费模式的改变,对垃圾食品和加工食品的依赖程度越来越高,这往往与当今生活方式紊乱有关。牙齿健康状况是生活方式选择和生活方式重大变化的明确指标。目的和目的:本研究的目的是评估西姆拉(喜马偕尔邦,印度)个人的牙齿健康状况,基于他们的初级牙科检查和基于访谈的数据。材料与方法:对301人(男性152人,女性149人)进行了龋齿、牙菌斑和牙周病的检查,并对他们的饮食摄入和生活方式进行了访谈。计算各齿型各状态的频率分布,并进行统计分析。结果:根据每个受试者的蛀牙、缺牙和补牙数量,计算龋缺牙-补牙平均指数为1.5182。计算的显著龋指数和菌斑指数分别为3.06和1.2872。上颌牙患病率(男女分别为59.2%和43.62%)高于下颌骨(男女分别为37.5%和47.5%)。调查显示,患龋最多的牙齿为第一前磨牙和第一磨牙(男性22.36%、女性30.87%);25%的男性和15.43%的女性在第一磨牙出现龋齿)。结论:总体牙齿健康状况显示,女性比男性有更多的牙齿健康状况恶化,但频率差异无统计学意义。饮食调查显示,他们的饮食中含有大量的糖,还有碳酸饮料和垃圾食品。

Amelogenesis imperfecta is a genetically determined inherited disorder characterized by abnormal formation of tooth enamel leading to esthetic, functional, and psychological impact on the patient. If teeth affected are not treated early; the existing condition will further deteriorate, leading to injury to the attachment apparatus complicating the proposed treatment plan and future prognosis. The definitive objectives of this rehabilitation were to eradicate tooth sensitivity while restoring masticatory function and enhancing esthetics. Treatment plan included root canal treatment of the decrepit teeth followed by porcelain fused to metal restoration. This case report highlight the prosthodontic management of a patient diagnosed with hypomaturation type amelogenesis imperfecta.
无釉质发育不全是一种由基因决定的遗传性疾病,其特征是牙釉质的异常形成,导致患者的审美、功能和心理影响。如果牙齿受影响没有及早治疗;现有的情况会进一步恶化,导致附着装置的损伤,使所提出的治疗方案和未来的预后复杂化。这种康复的最终目标是消除牙齿敏感,同时恢复咀嚼功能和提高审美。治疗方案包括对衰老牙进行根管治疗,然后进行烤瓷金属修复。本病例报告强调修复处理的病人诊断为低饱和型淀粉性发育不全。

Background: Ban on smoking in public places reduced the number of smokers considerably. According to Global Adult Tobacco Survey-2, tobacco use is decreased by 3% in Karnataka. However, the loose sale of tobacco products encourages the practice as tobacco users continue to use tobacco by purchasing loose tobacco products. Hence, the present study was carried out to assess the compliance of loose tobacco ban in Bidar city of Karnataka. Aim: The aim of this study is to assess the compliance on loose tobacco ban in Bidar City. Methods: The exploratory research design was used. The study was cross-sectional and community based in nature. Sample Size: 98; 50 vendors and 48 consumers were randomly selected using the time-cluster sampling. Data were collected from 22 different locations using the observation and interview method within 2 km radius of Bidar City. Two separate pretested and predesigned semi-structured interview schedules were administered to tobacco users and vendors. The study was carried out in November 2019. Ethical clearance was obtained from the Institutional Ethics Committee. Statistical analysis was done using the percentages and frequency tables. Results: Majority (96%) of the tobacco users were unaware of loose tobacco ban in Karnataka and prefer to buy cigarettes in loose. Four percent of tobacco users were aware that loose tobacco is banned. Majority of (76%) tobacco users think buying a full pack of cigarettes would increase smoking. There is absolutely no compliance on loose tobacco ban by tobacco vendors.
背景:禁止在公共场所吸烟大大减少了吸烟者的数量。根据全球成人烟草调查-2,卡纳塔克邦的烟草使用减少了3%。然而,烟草制品的随意销售鼓励了这种做法,因为烟草使用者通过购买散装烟草制品继续使用烟草。因此,本研究旨在评估卡纳塔克邦比达尔市松散烟草禁令的执行情况。目的:本研究的目的是评估比达尔市松散烟草禁令的执行情况。方法:采用探索性研究设计。这项研究是横向的,本质上是基于社区的。样本量:98;采用时间群抽样法随机抽取50家销售商和48家消费者。采用观察法和访谈法,在比达尔市2公里半径内的22个不同地点收集数据。对烟草使用者和销售商进行了两个单独的预先测试和预先设计的半结构化访谈计划。该研究于2019年11月进行。获得了机构伦理委员会的伦理许可。采用百分比表和频率表进行统计分析。结果:大多数(96%)烟草使用者不知道卡纳塔克邦的松散烟草禁令,更喜欢购买散装香烟。4%的烟草使用者知道散装烟草是被禁止的。大多数(76%)烟草使用者认为购买整包香烟会增加吸烟。烟草供应商绝对没有遵守松散的烟草禁令。
