Cases with missing molars do need a well-executed treatment plan and a thorough knowledge of biomechanics to treat which usually leads to its prosthetic rehabilitation instead of orthodontic management by the orthodontists. Its orthodontic management is not only time consuming but also requires patience and proper treatment strategy involving right choice of appliance and auxiliaries to achieve the best possible results. Here in this case series we have tried to show different treatment modalities in cases with missing permanent molars leading to ideal post treatment outcomes.
臼齿缺失的病例确实需要一个执行良好的治疗计划和全面的生物力学知识来治疗,这通常导致其假肢康复,而不是由正畸医生进行正畸治疗。其正畸治疗不仅耗时,而且需要耐心和正确的治疗策略,包括正确选择矫治器和辅助器具,以达到最佳效果。在这个病例系列中,我们试图展示在恒磨牙缺失的病例中不同的治疗方式导致理想的治疗后结果。

Biomaterials are the materials that are used for the restoration and reorganization of various tissues as well as organs. Some of the common materials presently used are organic, metallic, and composites. To increase the biocompatibility of these materials, some types of coatings are regularly applied. Hydroxyapatite is one of the materials which is mostly used for coating these materials. Hydroxyapatite acquires the same structural and chemical characteristics as human bone. In the present review, we discussed the various aspects of hydroxyapatite coatings that consist of rationale, coating process, various techniques, and coating failures.

Aim:The aim of this study is to evaluate the effect of different surface finish of various restorative materials on the wear of opposing enamel.Objectives of the study:1.To compare the amount of enamel loss in experimental groups of various restorative materials at different intervals of masticatory cycles. 2.To compare and evaluate the most compatible finished or polished surface of the restorative material causing least enamel wear. Materials and Methods: A total of 90 samples were prepared for this study - 75 in disc form and 15 enamel antagonist and divided into 6 groups. Group 1 - Enamel vs Enamel antagonist, Group 2 - Enamel vs Fiber Reinforced Composite disc, Group 3 Enamel vs  Autoglazed metal ceramic disc , Group 4 - Enamel vs  Overglazed metal ceramic disc, Group 5 - Enamel vs Polished  metal ceramic  disc by polishing kit, and Group 6 - Enamel vs PEEK disc were fabricated. 105 extracted premolars were collected and randomly divided into six groups of 15 each and 15 for enamel antagonist. Each tooth sample was weighed before wear testing using electronic analytical balance of 0.0001 g accuracy. Occlusal surfaces of these teeth were then abraded against the substrates in a wear machine for a total of 10,000 cycles. Each tooth sample was weighed after 5000 cycles and after the total of 10,000 cycles, respectively, using the same balance. Differences in weight of tooth samples before and after wear testing were evaluated statistically using One-way analysis of variance and Tukey’s post hoc tests was used. Results:  The values obtained for overall mean percentage weight loss after 10000 rotations in increasing order is observed: Group 1 (Enamel Vs Enamel 0.0043 ± 0.00) < Group 6 (Enamel Vs PEEK disc 00.0131 ± 0.01) < Group 2 (Enamel Vs Fiber reinforced composite 0.0258 ± 0.01) < Group 5 (Enamel Vs Polished metal ceramic disc 0.0294 ± 0.00) < Group 3 (Enamel Vs Autoglazed metal ceramic disc 0.0318 ± 0.01) < Group 4 (Enamel Vs Overglazed ceramic disc 0.0451 ± 0.01). Conclusion:PEEK showed the least amount of enamel wear followed by Fiber reinforced composite. Fiber reinforced composite may cause less wear than dental ceramics. Enamel wear produced by polished metal ceramic disc  is substantially less than autoglazed and over glazed metal ceramic disc. This study indicates that any potential damage to ceramic can directly affect enamel and suggests that porcelain should be polished instead of over glazed. Key Words: Fiber reinforced composite, Autoglazed, Overglazed, Polished  surface, Wear, PEEK.
目的:评价不同修复材料的不同表面光洁度对对牙釉质磨损的影响。本研究的目的:1。比较不同修复材料的实验组在咀嚼周期不同时间间隔的牙釉质损失情况。2.比较和评估修复材料最相容的抛光或抛光表面,使牙釉质磨损最小。材料和方法:本研究共准备了90个样品,其中盘状样品75个,搪瓷拮抗剂15个,分为6组。组1 -搪瓷vs搪瓷拮抗剂,组2 -搪瓷vs纤维增强复合材料盘,组3 -搪瓷vs自动上光金属陶瓷盘,组4 -搪瓷vs超上光金属陶瓷盘,组5 -搪瓷vs抛光金属陶瓷盘,组6 -搪瓷vs PEEK盘。收集拔牙前磨牙105颗,随机分为6组,每组15颗,牙釉质拮抗剂组15颗。每个牙齿样品在使用0.0001 g精度的电子分析天平进行磨损测试之前称重。然后,这些牙齿的咬合表面在磨损机中与基板摩擦,总共进行10,000次循环。每个牙齿样本分别在5000次循环和10000次循环后使用相同的天平称重。采用单因素方差分析和Tukey事后检验对磨损试验前后牙齿样本的重量差异进行统计分析。结果:获得总体的意思是百分比值减肥10000旋转增加订单后观察:组1(搪瓷Vs搪瓷0.0043±0.00)<集团6(搪瓷Vs PEEK盘00.0131±0.01)<组2(搪瓷与纤维增强复合0.0258±0.01)<集团5(搪瓷和抛光金属陶瓷盘0.0294±0.00)< 3组(搪瓷Vs Autoglazed金属陶瓷盘0.0318±0.01)<集团4(搪瓷与釉陶瓷盘0.0451±0.01)。结论:PEEK对牙釉质磨损最小,纤维增强复合材料次之。纤维增强复合材料比牙科陶瓷造成的磨损更小。抛光金属陶瓷盘产生的搪瓷磨损基本上小于自动上釉和过上釉金属陶瓷盘。这项研究表明,对陶瓷的任何潜在损伤都会直接影响珐琅质,并建议对瓷器进行抛光,而不是过度上釉。关键词:纤维增强复合材料,自动上釉,过釉,抛光表面,磨损,PEEK

Frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, gingiva, and the underlying periosteum. The frena may endanger the gingival health when they are attached closely to the gingival margin. An aberrant frenum is presupposed to create functional and aesthetic problems. Archer’s ‘classical frenectomy’ is an extensive procedure including the excision of fibers, interdental papilla, and exposure of the alveolar bone up to the palatine papilla. The aftermath delayed healing, loss of interdental papilla, and unusual scar led toward the traditional approaches such as Edward’s frenectomy, frenum relocation by Z-plasty, and free gingival graft, with their practical and esthetic restriction. A superior approach to make a primary closure in midline and to bypass anaesthetic scar by creating a zone of attached gingiva, frenectomy is associated with lateral pedicle graft. Miller, in his study on 27 subjects, proposed that newly created zone of attached gingiva may have bracing effect inhibiting reopening of diastema. A case report of this approach with its well defined benefits is presented.
系带是附着在嘴唇和脸颊上的粘膜褶皱,与牙槽黏膜、牙龈和下面的骨膜相连。系带与龈缘紧密附着时,会危害牙龈健康。一个异常的系带被认为会产生功能和美学问题。Archer的“经典系带切除术”是一项广泛的手术,包括切除纤维、牙间乳头和暴露牙槽骨至腭乳头。其后果是愈合延迟、牙间乳头缺失和不寻常的疤痕导致传统的方法,如爱德华系带切除术、z -成形术系带移位和游离牙龈移植物,其实用性和美观性都受到限制。系带切除术与外侧蒂移植物相结合,是在中线进行初级关闭并通过建立附着龈区来绕过麻醉疤痕的最佳方法。Miller在对27名受试者的研究中提出,附着龈新形成的区域可能具有支撑作用,抑制膈膜重新开放。此方法的一个案例报告,其明确定义的好处是提出。

Presently, it is known that pathogenic bacteria are the key factors for the initiation of periodontal disease, but the host response and the severity of clinical expression are largely determined by genetic susceptibility and environmental factors. There is evidence that the individual response to the environment and variations in the immune response in periodontitis are associated with genetic factors. The gene polymorphisms like interleukin-1 beta (IL-1b), interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-a) genes and their factors that determine the production of various cytokines which play an important role in the pathophysiology of inflammation and periodontal diseases. A sequel of this realization is that if the genetic basis of periodontal disease susceptibility can be understood, such information may have diagnostic and therapeutic value. This review focus to upgrade the general practitioners and periodontist about various genetic polymorphisms associated with periodontal diseases to aid in a better approach to the condition in the future.
目前,已知病原菌是牙周病发病的关键因素,但宿主反应和临床表现的严重程度在很大程度上取决于遗传易感性和环境因素。有证据表明,个体对环境的反应和牙周炎免疫反应的变化与遗传因素有关。白细胞介素-1 β (IL-1b)、白细胞介素-6 (IL-6)、肿瘤坏死因子- α (TNF-a)基因及其基因多态性决定各种细胞因子的产生,这些细胞因子在炎症和牙周病的病理生理中起重要作用。这一认识的结果是,如果牙周病易感性的遗传基础能够被理解,这些信息可能具有诊断和治疗价值。这篇综述的重点是提高全科医生和牙周病医生对各种与牙周病相关的遗传多态性的认识,以帮助将来更好地治疗牙周病。

Hemangiomas of the head and neck are benign tumours that have their origin from the blood vessels. Hemangiomas are classified as capillary, cavernous , sclerosing and central type. The nature of this tumour is progressively slow growing, including involvement of greater portions of the superficial and deep blood vessels, functions maybe affected, depending on the location. Hemangiomas are common in the head and neck and have rare occurrence in the oral cavity. Lips, buccal mucosa and tongue are the common sites, hemangiomas occur rarely on the palate. This is a case of unusual location of capillary hemangioma on the palate in a middle aged man diagnosed by histopathology after surgical excision.
头颈部血管瘤是起源于血管的良性肿瘤。血管瘤分为毛细血管型、海绵状、硬化型和中心型。这种肿瘤的性质是逐渐缓慢生长,包括累及大部分浅层和深层血管,功能可能受到影响,这取决于位置。血管瘤常见于头部和颈部,很少发生在口腔。唇部、颊黏膜和舌是多发部位,上颚血管瘤很少发生。这是一例在手术切除后经组织病理学诊断的中年男性上颚毛细血管瘤的异常位置。

Abstract Aims and objectives: Tic douloureux is another name for trigeminal neuralgia (TN). The first report of TN can be found in the writing of Avicenna in the 11th century, but John Fothergill gave the modern description of TN in his 1773 paper on the subject. The present study was conducted to evaluate the prevalence of Trigeminal Neuralgia (TGN) among north Indian population. Materials and methods: A cross-sectional descriptive study on the prevalence of Trigeminal neuralgia was conducted in the outpatient department of Oral Medicine and Radiology during a period of 5 years (1 January 2015 to 31 December 2019) months. All selected patients over the age of 18 were asked for their TN history using a structured questionnaire based on diagnostic criteria of trigeminal neuralgia according to the beta-version of the 3rd edition of the International Classification of Headache Disorders (ICHD3-beta) after acquiring their personal data (name, age, gender and address).Descriptive statistics included calculation of means and percentages. Data distribution was assessed for normality using Shapiro-Wilk test to check whether a sample came from a normally distributed population or not. The chi-square test is used to determine whether there is a significant difference between the expected frequencies and the observed frequencies in one or more categories. Student’s t-test was used to test the means between the samples. All values were considered statistically significant for a value of p<0.05. Results: Results: Out of 1500 patients, 26.67%were male and 73.33% were female. The peak incidence was in the age range of 60-70 years. Maxillary nerve (71.1%) was most commonly is involved followed by mandibular (20.2%) and ophthalmic (8.7%) nerve. The right side of the face (80%) was more involved than the left side (20%) of the face. The majority of patients described their attack as a shock like and of spontaneous onset. Conclusion: TN is often misdiagnosed as toothache, resulting in root canal therapy and tooth extractions. To recognize and manage this problem, an interprofessional strategy involving the primary care physician, dentist, neurologist, anesthesiologist, and neurosurgeon is required. Correct diagnosis and management can benefit patients and result in a good prognosis.
目的和目的:Tic douloureux是三叉神经痛(TN)的别名。关于TN的第一份报告可以在11世纪阿维森纳的著作中找到,但是约翰·福瑟吉尔在他1773年关于这个主题的论文中给出了TN的现代描述。本研究旨在评估印度北部人群中三叉神经痛(TGN)的患病率。材料和方法:对口腔医学和放射科门诊三叉神经痛的患病率进行了为期5年(2015年1月1日至2019年12月31日)的横断面描述性研究。在获取个人资料(姓名、年龄、性别和地址)后,根据第三版国际头痛疾病分类(ICHD3-beta)的三叉神经痛诊断标准,使用结构化问卷询问所有年龄在18岁以上的患者的TN病史。描述性统计包括均值和百分比的计算。采用Shapiro-Wilk检验检验数据分布是否为正态分布,以检验样本是否为正态分布。卡方检验用于确定在一个或多个类别中预期频率与观测频率之间是否存在显著差异。使用学生t检验来检验样本间的均值。以p<0.05为差异有统计学意义。结果:1500例患者中,男性占26.67%,女性占73.33%。发病高峰年龄在60 ~ 70岁。最常受累的是上颌神经(71.1%),其次是下颌神经(20.2%)和眼神经(8.7%)。右侧面部(80%)比左侧面部(20%)更受影响。大多数患者描述他们的发作为类似休克的自发性发作。结论:TN常误诊为牙痛,导致根管治疗和拔牙。为了认识和处理这个问题,需要一个包括初级保健医生、牙医、神经科医生、麻醉科医生和神经外科医生在内的跨专业策略。正确的诊断和处理可以使患者受益并获得良好的预后。

All values were considered statistically significant for a value of p<0.05. \u0000Results: Results: Out of 1500 patients, 26.67%were male and 73.33% were female. The peak incidence was in the age range of 60-70 years. Maxillary nerve (71.1%) was most commonly is involved followed by mandibular (20.2%) and ophthalmic (8.7%) nerve. The right side of the face (80%) was more involved than the left side (20%) of the face. The majority of patients described their attack as a shock like and of spontaneous onset. \u0000Conclusion: TN is often misdiagnosed as toothache, resulting in root canal therapy and tooth extractions. To recognize and manage this problem, an interprofessional strategy involving the primary care physician, dentist, neurologist, anesthesiologist, and neurosurgeon is required. Correct diagnosis and management can benefit patients and result in a good prognosis.","PeriodicalId":100856,"journal":{"name":"King Saud University Journal of Dental Sciences","volume":"7 22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85556551","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}

Surgical removal of impacted lower wisdom tooth remains as the most common dental surgical procedure that is performed on outpatient basis. In the present study, a total of 40 patients with impacted lower wisdom tooth underwent surgical extraction under local anaesthesia by using Normal saline as irrigating solution at two different temperatures that is refrigerated at 8-degree Celsius temperature and other NS at room temperature. The patients underwent standard operating procedures and medication. Post-operative complications in terms of pain, swelling, infection and delayed wound healing were assessed and compared on Day 1 and Day 3and 7th day after surgery. The result of this study showed that irrigation with cold saline decreases the post-operative complications and enhances the healing after third molar removal. A bigger scale of research with more samples is recommended to evaluate the most efficacy irrigating solution during surgical removal of impacted lower wisdom tooth.  
手术切除阻生下智齿仍然是最常见的牙科手术,在门诊进行的基础上。本研究共选取40例埋伏下智齿患者,在局麻状态下,采用生理盐水作为冲洗液,在8℃温度下冷藏,其他NS在室温下冷藏,进行手术拔牙。患者接受了标准的手术程序和药物治疗。在术后第1天、第3天和第7天评估和比较术后并发症的疼痛、肿胀、感染和伤口愈合延迟。结果表明,冷盐水冲洗可减少第三磨牙拔除术后并发症,促进第三磨牙拔除后的愈合。建议进行更大规模、更多样本的研究,以评估手术拔除埋伏下智齿时冲洗液的最有效效果。

Idiopathic gingival enlargement is a rare non-hemorrhagic, slowly proliferative fibrous lesion of the gingival tissue in which no causative agent can be identified. These type of enlargement causes esthetic and functional problems. This case report highlights the diagnosis and treatment of the idiopathic gingival enlargement of a 14 years old female patient who presented with a generalized diffuse type of gingival enlargement in both the maxillary and mandibular arches which covers maximum portion of the crowns. Based on family history and clinical examination, diagnosis was made following which segment wise gingivectomy was carried out. Histopathologic evaluation was also done. Post operative enlargement was noticed on first week which gradually decreased to some extent in the third week post operatively.
