The etiology is congenital or idiopathic and include trauma, arthritis, infection, previous TMJ surgery etc. Management requires extensive resection of the ankylotic mass and reconstruction of the ramus-condyle unit with autogenous or alloplastic grafts. Most of the time, combination of surgical treatment with physiotherapy is needed in order to achieve maximum rehabilitation and functionality of the mandible.</p> <p><strong>Purpose:</strong> The aim of this study is to present the surgical management of an unusual case of unilateral TMJ ankylosis and recent of literature review.<br /> Case report: A thirty-seven-year old patient reported unable moving his lower jaw. Clinical examination revealed unilateral TMJ ankylosis of congenital cause and the lateral movement of the mandible was impossible. The patient surgical treatment included resection of the newly formed bone mass, replacement of the condyle with costo-chondral graft and replaced of articular disc with the temporal fascia. Since and for ten years after surgery the patient shows no signs of relapse.</p> <p><strong>Conclusion:</strong> The development of TMJ ankylosis may be congenital or acquired etiology. In order to manage it required a comprehensive clinical and radiographic examination. Surgical resection of the bone and coronoid process on the entire side is necessary and a graft that mimics the articular disc is placed, while it is necessary the immediate postoperative kinesiotherapy.</p> 12/30/2019//m.lakotalakes.com/johcs/johcs-aid1029.php & lt; h2> Abstract< / h2><p>Parry-Romberg syndrome is an uncommon condition, self-limiting with slow progressive hemifacial atrophy. This syndrome can lead to several progressive congenital and developmental deformities. It can cause severe facial asymmetry and subsequently lead to esthetic and psychological problems and adversely affect patient&rsquo;s quality of life, so its treatment holds great importance. Still, there is no exact treatment protocol for this disease, treatment approaches are bounded and patient&rsquo;s response to the treatment is imponderable. However, most of the patients can benefit from conservative treatments. In this paper, we have reported a moderate case of Parry-Romberg syndrome, with no familial history of any syndromes. We also have discussed about present anomalies and the steps of exerted conservative treatments.</p> 08/28/2019//m.lakotalakes.com/johcs/johcs-aid1028.php & lt; h2> Abstract< / h2>& lt; p>皮埃尔玛丽亚和Sainton综合症或cleido-cranial发育不良(CCD)是一种罕见综合症的一种常染色体的遗传模式,特点是表现为一个三和弦:锁骨发育不全、延迟囟门骨化,缝合线的头骨的金库。这些可以添加多个牙夹杂物。;/ p> 08/13/2019//m.lakotalakes.com/johcs/johcs-aid1027.php & lt; h2> Abstract< / h2>& lt; p> & lt; strong>背景:& lt; / strong>本研究进行了评估吸烟的影响在不同的假牙基材。你们;/ p>& lt; p> & lt; strong>材料,amp;Methods< / strong>:目前的研究是在美国进行的假牙修复术。总共六十石蜡标本形状的圆形盘准备。这些被分为两组。组我(30)标本heata€“固化义齿基材料和组II(30)标本基础弹性义齿材料。标本都是15每进一步分为四个亚组。子群我heata€“治愈假牙基材标本(对照组),子群二世是弹性义齿基材标本(对照组),第三组是heata€“治愈假牙基材标本暴露于吸烟(研究组)和第四子群弹性义齿基材标本暴露于吸烟(研究小组)。 The initial (IRa) and final (FRa) surface roughness was measured before and after smoking test of the specimens.</p> <p><strong>Results</strong>: It was observed that in group I, mean IR (&micro;m) value was 0.182 and FR value was 0.572.

From history and examination alone, clinicians reported significant findings on 50.3% of records, while 43.6% had no such findings. Ten (10) (6.1%) records were unclear. Examination of OPGs revealed 79.1% of the films had no pathological findings while in 20.9% had. Most of the findings (70.0%) were retained roots, 6% were radio-lucencies, 12% were other radio-opacities, 9% were impacted teeth while 3% had both retained root and radio-opacity. Most pathologies (64%) were located in the posterior region of jaws while the other findings were evenly distributed in the anterior and posterior regions of the jaws. There was no predilection of pathological findings to any other factor other than gender. In 83.4% records, queries on clinical notes coincided with significant findings on OPGs; while 16.6% were either unclear or did not coincide. Most (71%) OPG findings led to modification of treatment plan.</p> <p><strong>Conclusion</strong>: Pathological findings are common on pre-treatment OPGs. It may be good practice to take an OPG for edentulous patients prior to complete denture therapy where such services are available, to prevent complications from intra-bony pathologies. However, Most of the findings are either detectable by clinical exam or may not be of major consequence to the health of patients. Complete denture may be done without OPGs for new and old denture wearers where the service is not available.</p> 02/09/2018//m.lakotalakes.com/johcs/johcs-aid1023.php <h2>Introduction</h2> <p>Salivary stone (sialothiasis) is a calcifying concentration within the ductal system of salivary gland [1].

The complexity of open bite is attributed to a combination of skeletal, dental and habitual factors. Etiology of open bite can be attributed to genetics, anatomic and environmental factors.However, the tendency toward relapse after conventional or surgical orthodontic treatment has been indicated. Therefore, open bite is considered one of the most challenging dentofacial deformities to treat. The aim of this article is to emphasize that early etiological diagnosis, dentofacial morphology and classification are essential to the successful outcome of the technical intervention. Failure of tongue posture adaptation subsequent to orthodontic and/or surgical treatment might be the primary reason for relapse of open bite. Prolonged retention with fixed or removable retainers is advisable and necessary in most cases of open bite treatment. The treatment of open bite remains a tough challenge to the clinician; careful diagnosis and timely intervention with proper treatment modalities and appliance selection will improve the treatment outcomes and long-term stability.</p> 01/10/2018//m.lakotalakes.com/johcs/johcs-aid1021.php & lt; h2> Abstract< / h2>& lt; p>纠正二类咬合不正一直挑战牙齿矫正医师由于复杂和多因子的病因学。年龄的病人和选择设备中发挥着重要作用的结果治疗。amp;,增长修改使用功能电器在二类病人达到稳定的结果。牙齿矫正医师有各种各样的固定和可移动的电器的处理异常咬合II。综述文章尝试编译各种可用的固定功能电器。你们;/ p> 11/24/2017//m.lakotalakes.com/johcs/johcs-aid1020.php & lt; h2> Abstract< / h2>& lt; p>坏死性筋膜炎是一种快速进步软组织感染,可以用扩散描述皮下组织坏死和浅筋膜。amp;,这可能是感染的原因过程中牙原性的起源,最常见的引起的混合克+和克,有氧和厌氧微生物中发现患者倾向于感染。在确诊疾病的情况下,有可能危及生命的并发症。本案例分析介绍疾病的诊断标准和治疗计划,鼓励医生们将更多的精力用在预防感染。;/ p> 11/02/2017//m.lakotalakes.com/johcs/johcs-aid1019.php & lt; h2> Abstract< / h2>& lt; p> & lt; strong>目的:& lt; / strong>评估和学习老年患者口腔健康意识和卫生习惯和识别重要的壁垒建立口腔健康服务、疾病预防和口腔健康促进项目相同的。你们;/ p>& lt; p> & lt; strong>材料和Methods< / strong>:共有500名患者在50年以上的年龄段选择使用随机抽样技术。一个selfa€结构化问卷调查包括20多项选择题给他们。结果使用比例关系,进行了分析;/ p>& lt; p> & lt; strong> Results< / strong>:这项研究的结果显示了急性缺乏口腔卫生意识和口腔卫生行为的有限的知识。在罗西尼,很少人使用牙刷。;/ p>& lt; p> & lt; strong> Conclusions< / strong>:因此,有迫切需要全面的教育计划,促进良好的口腔卫生,对正确的口腔卫生实践。你们传授教育;/ p> 10/26/2017//m.lakotalakes.com/johcs/johcs-aid1018.php & lt; h2> Abstract< / h2><p>Selective alveolar decortication and periodontal augmentation with a bone graft were the two procedures used for the correction of the skeletal class II malocclusion in the case reported.A 25-year-old male patient presented with a skeletal class II malocclusion with increased bi-maxillary dento-alveolar protrusion, increased overjet, deep bite and imbricated and rotated mandibular incisors with bilateral presence of supernumerary teeth in the maxillary right and left premolar regions. Extraction of supernumerary in the maxillary right and left premolar region, and impacted UL5 was done. Pre-adjusted edgewise appliance, Roth&rsquo;s prescription (0.022x0.028-inch slot), was bonded and a week later full thickness labial and lingual flaps were reflected in the maxillary and mandibular arches. Circumscribed corticotomy cuts was done and subsequently augmented with a bone graft. Orthodontic treatment was commenced immediately after surgery and orthodontic adjustments were performed every 2 weeks. The entire orthodontic treatment was completed in 9 months. Regional acceleratory phenomenon, triggered by the alveolar decortication, was responsible for the rapid correction of the malocclusion and the augmentation with the bone graft provided adequate bone volume for housing the teeth, thereby decreasing the possibility of subsequent relapse.</p> 10/05/2017//m.lakotalakes.com/johcs/johcs-aid1017.php & lt; h2> Abstract< / h2><p><strong>Introduction</strong>: One of the essential requirements for efficient oral and maxillofacial surgeon is comprehensive knowledge in anatomy of head and neck regions. Authors believe that asking students to draw anatomical<br /> sketches will assist them to improve their imaginary memory for human anatomy.

This in vivo&nbsp; study was conducted to evaluate the efficacy of resin modifi ed glass ionomer cement (RMGIC) on reducing enamel demineralization around orthodontic brackets and confirm the superior caries-preventive effect of RMGIC by assessing the mutans streptococci (S.mutans) in plaque samples in vitro.</p> <p><strong>Methods</strong>: 60 subjects (aged 14-20 years) scheduled to have premolar extractions as part of the orthodontic treatment plan were selected and randomly divided into 2 groups of 30 each (group 1: the brackets were bonded on the teeth using light cure composite resin and group 2: the brackets were bonded using RMGIC). Plaque scores (modification of plaque index by Silness and Loe) were recorded and plaque samples were collected before bonding, one week and one month after bonding. S.mutans colonies were recorded from the plaque samples inoculated on MSB agar plates, incubated under 95% N2 and 5% CO2 for 48 hours at 370C in a CO2 jar. After 1 month, the right maxillary and mandibular first premolars were debonded, extracted and depth of enamel demineralization area was estimated using polarized light microscope.</p> <p><strong>Results</strong>: After statistical analysis, a significantly higher mean depth of demineralized lesions was noticed in group 1 as compared to group 2. A significant difference between occlusal and gingival depth was seen only in group 2, thus illustrating a wedge effect. In group 1, a statistically significant increase in the mean colony forming units (CFU) of S.mutans has been noticed at different time intervals whereas in group2, a significant increase was observed only at 1month. Unlike at 1 month, a statistically significant difference in mean CFU between group 1 and group 2 has been observed at 1 week (P&lt;0.05).</p> <p><strong>Conclusions</strong>: Enamel lesions adjacent to the bracket base on teeth bonded with the RMGIC were smaller than those on teeth bonded with a composite resin. The high &ldquo;burst effect&rdquo; of fluoride release for the first few days of RMGIC after bonding is confirmed by statistically significant reduction in CFU counts of S. mutans in plaque.</p> 06/22/2017//m.lakotalakes.com/johcs/johcs-aid1013.php & lt; h2> ABSTRACT< / h2>& lt; p> & lt; strong>问题的声明:& lt; / strong>前牙骨折,由于创伤性损伤,经常发生在牙科。这导致坏死的牙髓和根尖周的病理变化。牙髓学的和恢复性牙科的目标是保留自然牙齿最大功能和令人愉悦的美学。;/ p>& lt; p> & lt; strong> study<的目的;/ strong>:本研究旨在广泛的重建受损牙齿的过程称为,“生物修复。amp;”, & lt; / p>& lt; p> & lt; strong>材料和methods< / strong>:生物通过自然,提取牙齿从另一个人代表了一个低成本的选择和替代技术形态功能恢复受损的前牙提供高功能和审美的结果。你们;/ p>& lt; p> & lt; strong> Conclusions< / strong>:这种情况下报告指的是美学和功能恢复的下颌侧切牙periradicular非手术治疗后病变。;/ p> 05/12/2017//m.lakotalakes.com/johcs/johcs-aid1012.php & lt; h2> ABSTRACT< / h2>& lt; p>恢复部分或完全无齿的患者植入假体已广泛应用的支持,实现较高的成功率。然而,许多研究认为夜间磨牙症的存在是一个禁忌的治疗模式。本研究的目的是审查的文学和识别风险因素植入与磨牙症受试者的康复计划的支持。恢复bruxers使用植入假体的支持,使用植入与足够的长度和直径,以及适当的定位,似乎是一个可靠的治疗降低了失败的风险。夜间磨牙症控制通过使用刚性咬合的稳定装置的夜班警卫,缓解该地区的植入物,是高度表示。虽然很明显,植入磨牙症患者的康复需要足够的支持计划和后续,需要设计良好的随机对照试验提供可靠的证据的长期成功的治疗模式灵活;/ p> 05/09/2017//m.lakotalakes.com/johcs/johcs-aid1011.php & lt; h2> ABSTRACT< / h2><p>Clowning is a form of humour. It is an art form that invites play, interaction, and laughter. Clown Care is a programme in hospitals and medical centres involving visits from specially trained hospital clowns. Clowning helps patients to focus on something other than their illness. Olsson et al. and Spitzer suggested that clown care could create a warm climate, promote good interpersonal relationships, and relieve feelings of frustration, anxiety, or hostility.Hospital clowns work worldwide as a health humanization resort, providing interplay with patients, family and staff creating a positive emotional state that fosters affirmative environmental conditions. This type of activity varies greatly in terms of professionalism, accountability and artistic methods. Promotion of emotional and psychosocial well-being of patients transcends opportunities for oral health promotion activities in hospitals, schools and community. Previous research reports on clown training reflects attitude-building potential for the healthcare students provided that it is performed in a deep, essential, strict and continuous fashion in a facultative manner rather than mandatory allowing the student to build his own artistic, professional and personal path. Thus, the prospect of introducing training curriculum of this underrated non-technical skill for dental students in Indian dental education system needs to be harnessed.</p> 04/26/2017//m.lakotalakes.com/johcs/johcs-aid1010.php & lt; h2> ABSTRACT< / h2>& lt; p>第三臼齿提取影响的迹象包括预防牙齿邻牙再吸收。吸收可分为生理(当乳牙脱落)或病理(当造成的损伤或刺激牙周韧带)。很多原因可以触发外部根吸收(ERR),最常见的原因是矫正力量。最常见的情况下犯错涉及影响第三磨牙,由于缺乏空间的爆发,产生更大的机会宁可第二磨牙的远端部分。病理学是临床牙科保健变得越来越频繁。根尖周的评估和全景片是用来帮助诊断,锥束ct。在锥束ct扫描,检测到射线可透过的不规则的地区差距;这些差距代表牙科材料的重大损失。这篇文章的目的是报告的第二个克分子吸收引起的影响第三磨牙和执行审查文学的根吸收外部的原因。 Ideally, this information will aid dental clinicians (and orthodontists in particular) in understanding the features of this pathology so that they may recommend preventive third molar extraction when necessary.</p> 04/07/2017//m.lakotalakes.com/johcs/johcs-aid1009.php & lt; h2> ABSTRACT< / h2><p>The recent introduction of the miniscrew in orthodontics revolutionized the clinical and biomechanical approach of anchoring.

The basal angle range of 103.6&deg;-126.4&deg; may be used as a guide for the potential range of normal skull base angles in Thai population and possibly also the Southeast Asian population.</p> 03/10/2017//m.lakotalakes.com/johcs/johcs-aid1005.php & lt; h2> ABSTRACT< / h2><p><strong>Aim: </strong>To evaluate sexual dimorphism in horizontal lip position in adults with different skeletal patterns.</p> <p><strong>Material and Methods</strong>: The sample comprised of 120 patients (Females 18 years and above, Males 21 years and above) with no history of previous orthodontic treatment or functional jaw orthopaedic treatment. They were divided into different groups based on the ANB angle and gender. Group I and II included 30 males and 30 females with skeletal class I malocclusion (ANB 0-4 degree). Group III and IV included 30 males and 30 females with skeletal class II malocclusion respectively (ANB above 4 degree).</p> <p><strong>Results</strong>: When comparison between males and females (Class I+Class II) was done S-line (p&lt;0.001), B-line (p&lt;0.001), E-line (p&lt;0.001), Holdaways angle (p&lt;0.001) and Merrifield angle (p&lt;0.001) were found to be statistically significant. S-line (p&lt;0.001), E-line (p&lt;0.001) and Holdaways angle (p&lt;0.001) were found to be statistically significant when comparison was done between males and females (Class I). When comparison was done between males and females (Class II) only Holdaways angle (p&lt;0.001) showed a significant statistical difference.</p> <p><strong>Conclusion</strong>: Sexual dimorphism was found in various lip parameters. Significant amount of differences were found between Class I and Class II (male and female) subjects.</p> 12/30/2016//m.lakotalakes.com/johcs/johcs-aid1003.php & lt; h2> Review< / h2>& lt; p>口腔癌倾向于被发现在后期是有害的患者由于其高死亡率和患病率(存活率15 - 50% [1])。口腔癌的发病率在全球范围内大约是所有恶性肿瘤的3%,因此创建一个重要的全球卫生问题[2]。最常见的口腔癌症是鳞状细胞癌(SCC),占所有癌症的96%的口腔[3]。amp;,口腔鳞状细胞癌(OSCC)和口咽咽鳞状细胞癌是世界上第六个最常见的恶性肿瘤今天[4]。口腔癌的平均存活率五年,远低于其他癌症[5]。早期检测将允许口腔癌90%可治愈的和成本有效的治疗[6]。;/ p>& lt; p>口腔癌的早期检测是重要的因此减少死亡率致命的疾病的发病率。方法可用于早期检测涉及到在口头cancer&知识渊博的,病因,检测和检查方法为临床医生需要遵循的进步的方法检测。能力,受过良好教育的口腔卫生保健提供者需要提供适当的口腔癌筛查检查,早期口服,头部和颈部癌症检测。OSCC筛查的检出率只有0.12% [7]。 Therefore, we focused on the important of advanced screening and detecting methods for early diagnosis of oral premalignant and malignant lesions.</p> <p>Tobacco use and alcohol consumption are regarded as the main risk factors for oral squamous cell carcinoma (OSCC) table 1, while human papilloma virus (HPV) infection is emerging as the leading risk factor in cancers of the oropharynx.

Quantitative description is possible by measuring the relative bone density, which puts the mean grey value of a certain area in relation to the surrounding bone tissue.&nbsp;In this research the intra- and interindividual variability is determined for this method and a standard operation procedure is elaborated.</p> <p>Therefore ten panoramic radiographs of typical surgical indications in oral a maxillofacial surgery were analyzed by three different members of the workgroup, five times each. The measurements were analyzed with descriptive and comparative statistical methods.</p> <p>The mean coefficient of variation was 2.972% &plusmn; 2.361%. The measurements of defect regions were more consistent (2.252% &plusmn; 1.928%) than the measurements of surrounding bone (3.691% &plusmn; 2.626%). The analysis of variance did not show a statistically significant influence of the different raters to the measurements (ANOVA, Pr&gt;F = 0.9462).</p> <p>Following the standard operation procedure this method seems to be an easy, cheap and close to practice way to visualize healing process of the jaws. Especially in the mandibula, but also in the maxilla with special reconsideration of the sinus-region, it seems to be suitable.</p> 11/30/2016//m.lakotalakes.com/johcs/johcs-aid1001.php & lt; h2> Abstract< / h2><p><strong>Objective:</strong> The aim of the study was to determine the compliance to infection control of various dental laboratories in Durban.</p> <p><strong>Study design: </strong>This was a qualitative survey.</p> <p><strong>Setting: </strong>Dental laboratories in Durban area, South Africa.</p> <p><strong>Subject</strong>: Registered laboratory technicians.</p> <p><strong>Study methodology</strong>: Convenient random sampling method was used.</p> <p><strong>Results</strong>: There was poor compliance to infection control procedures by most dental laboratories. Majority, 66.67%, of the dental laboratories relied on dental clinics for disinfection of dental impressions; therefore, they did not disinfect the impressions. On the other hand, only 33.33% carried out disinfection of dental impressions on their own. A high number (53.3%) of the respondents had disinfection areas within their dental laboratories, 6.7% had no disinfection areas while 40% depended upon dental clinics for all disinfections. About 60% of the dental technicians had valid vaccinations against Hepatitis B Virus while 40% had no vaccination against HBV.</p> <p><strong>Conclusion</strong>: The results of this study indicated that there was substantial nonconformity to infection control measure in all dental laboratories. There should be comprehensive inspection of dental laboratories prior to licensing and thereafter by the South African Dental Technician Council&rsquo;s inspectors to ensure that all dental laboratories comply with the various infection control measures.</p>
