The aim of the present study is to determine the ?community indicator? for dental caries among secondary school children within the Federal Territory of Kuala Lumpur (FTKL). School factors were investigated for their ability to be used as community indicators. The components encompassing school factors include: type of school, school?s examination performances at the Peperiksaan Menengah Rendah (PMR) level, in the subjects of Mathematics, Bahasa Melayu (Malay Language), Science and English, school?s socioeconomic circumstances and school?s material deprivation. The study design is ecological in nature where schools were the unit of analysis. It used aggregated data for caries experiences acquired from the Oral Health Management Information System and the school factors which were extracted from the schools? database. The subjects involved in this study were all the (75) day type secondary schools in FTKL. However, only 55 schools had complete information both for the dental caries factor and the school factors which were available for analysis. The use of bivariate analysis suggested that the school mean DMFT was significantly associated with the schools? performance in English (p= 0.02) and the schools? socioeconomic code (p= 0.005). The schools? performance in English and socioeconomic code were able to explain about 10 percent and 14 percent of the variation in the school mean DMFT respectively. The final model that included both variables together explained about 17 percent of the variation in school mean DMFT. As a conclusion, this study suggests that the schools? performance in English at the PMR level and the schools? socioeconomic code could be used as community indicator to identify secondary schools with higher caries level in FTKL. Nevertheless, further improvement of the model is needed in order to create a more reliable indicator.
本研究的目的是确定“社区指标”。在吉隆坡联邦领土(FTKL)内的中学生中进行龋齿调查。调查了学校因素作为社区指标的能力。学校因素的组成部分包括:学校类型,学校?他在PMR水平的数学、马来语、科学和英语考试中的表现如何?美国的社会经济环境和学校?S物质匮乏。研究设计本质上是生态的,以学校为分析单位。它使用了从口腔健康管理信息系统中获得的龋病经验的汇总数据和从学校中提取的学校因素。数据库。本研究的研究对象为FTKL市全部(75所)日制中学。然而,只有55所学校有完整的龋齿因素和学校因素信息可供分析。双变量分析的使用表明,学校平均DMFT与学校?学生的英语表现(p= 0.02)和学校?社会经济代码(p= 0.005)。学校吗?英语和社会经济代码的表现能够分别解释学校平均DMFT的10%和14%的变化。包括这两个变量的最终模型解释了学校平均DMFT中约17%的差异。作为结论,这项研究表明,学校?在PMR级别和学校的英语表现?社会经济代码可以作为社区指标来识别FTKL中较高龋病水平的中学。然而,为了创造一个更可靠的指标,需要进一步改进模型。

One of the many growth anomalies that affect the mandibular condyle is hemimandibular elongation without any condylar hyperplasia. Condylar growth patterns can be evaluated by serial clinical comparisons, cephalometric tracings and bone scanning with technetium 99m phosphate. However, no ideal method has been found to assess whether condylar overgrowth is “inactive”. Therapy is guided by the patient's age and condylar growth activity. Treatment modalities have ranged from condylectomy to orthopedic maxillary management. A case is presented where one such patient was treated with condylectomy and a long follow-up of seven years showing stable results after surgery.
影响下颌髁的许多生长异常之一是半下颌延伸而没有任何髁突增生。髁突生长模式可通过一系列临床比较、头侧显像和99m磷酸锝骨扫描来评估。然而,尚无理想的方法来评估髁突过度生长是否为“非活动”。治疗应根据患者的年龄和髁突生长活动情况进行指导。治疗方式从髁突切除术到矫形上颌手术。一个病例是提出,其中一个这样的病人是治疗与髁突切除术和长期随访7年显示稳定的结果后手术。

A late adolescent patient presented with a Class III malocclusion on a skeletal Class III base, complicated by severe upper arch and moderate lower arch crowding, reverse overjet, anterior and bilateral posterior crossbites with displacement, proclined upper incisors, retroclined lower incisors, distally tipped lower canines and non-coincident centrelines. Treatment was undertaken on an extraction basis by employing the use of an upper removable appliance with Z-springs and posterior bite blocks to correct the anterior crossbite, quad helix and jockey arch for arch expansion, and pre-adjusted edgewise fixed appliance to level and align, space closure and achieve a mutually protective functional occlusion. This paper discussed the rational and evidences behind the treatment employed.

This cross-sectional study was carried out to identify A. actinomycetemcomitans and P. intermedia in the subgingival plaque of three ethnic groups (Malays, Chinese and Indians) in a selected group of adult Malaysians with advanced Chronic Periodontitis and to correlate these findings with their periodontal status. Thirty periodontally diseased adults were age, gender and ethnically matched with 30 healthy individuals. Clinical parameters were assessed for all. Subgingival plaque samples were collected for identification of A. actinomycetemcomitans and P. intermedia using polymerase chain reaction. Prevalence for P. intermedia (83.3%) was high and A. actinomycetemcomitans (6.7%) low in the total subject population. P. intermedia and A. actinomycetemcomitans were more prevalent in diseased (86.7%, 10% respectively) than in healthy (80%, 3.33% respectively) subjects. A. actinomycetemcomitans was detected in 15% Indians, 5% Malays but none of the Chinese subjects whereas P. intermedia was detected in 90% Malays, 85% Indians and 75% Chinese subjects. No significant association between presence of A. actinomycetemcomitans and P. intermedia with race and periodontal disease status was found. Only A. actinomycetemcomitans had a significant association with clinical attachment level (CAL) (p < 0.05). In conclusion, in this small subject group, none of the pathogens were associated with race and periodontal disease status and only A. actinomycetemcomitans had a significant association with CAL.
本横断面研究的目的是在一组患有晚期慢性牙周炎的马来西亚成年人中,在三个种族(马来人、华人和印度人)的龈下菌斑中鉴定放线菌属和中间假单胞菌,并将这些发现与他们的牙周状况联系起来。30名患牙周病的成年人与30名健康人年龄、性别和种族相匹配。评估所有患者的临床参数。收集龈下菌斑标本,采用聚合酶链反应法鉴定放线菌单胞菌和中间假单胞菌。总体人群中,中间假单胞菌的患病率较高(83.3%),放线菌comitans的患病率较低(6.7%)。中间假单胞菌和放线菌合成假单胞菌在患病人群中的患病率分别为86.7%和10%,高于健康人群(分别为80%和3.33%)。在15%的印度人、5%的马来人、75%的华人受试者中检测到放线菌,而在90%的马来人、85%的印度人和75%的华人受试者中检测到中间病原菌。放线菌和中间假单胞菌的存在与种族和牙周病状况无显著关联。只有放线菌与临床依恋水平(CAL)有显著相关性(p < 0.05)。总之,在这个小的受试者组中,没有病原体与种族和牙周病状态相关,只有放线菌球菌与牙周病有显著关联。

Polishing of the composite resin restorations ? literature review. 复合树脂修复体的抛光?文献综述。
Pub Date : 2010-12-31 DOI: 10.22452/ADUM.VOL17NO1.5

The widespread use of aesthetic fillings has highlighted their advantages and disadvantages. One of the most troublesome features of earlier aesthetic materials was the difficulty of finishing the restoration surface to decrease adherence of food debris. The rougher the finished surface, the greater the possibility of bacterial accumulation and discolouration of restoration along the restoration margin with secondary caries formation. Aside from these clinical implications, patients are highly discerning and could detect roughness of 0.30 ?m with their tongue. The aesthetic restoration should mimic the appearance of natural dentition and should have an enamel-like appearance. An increased demand for superior aesthetics from composite resin has increased the demand for more eff icient and simple polishing techniques. The development of nanocomposites has given a new perspective to the polishing of composite resins. Nanocomposites claim the advantage of improved gloss, optical characteristics and reduced wear. To date, results of in vitro studies have been equivocal regarding the most efficient and effective polishing system. There is variation in the effects of different finishing and polishing instruments on the surface roughness due to great diversity in size, shape, composition and distribution of the filler particles of composite resins, type of resin and a wide variety of finishing and polishing instruments. This paper will review the different factors that affect polishing techniques used in achieving the desired polish on composite resin restorations.
美学填充物的广泛使用凸显了它们的优点和缺点。早期美学材料最麻烦的特点之一是难以完成修复表面,以减少食物碎屑的粘附性。加工后的表面越粗糙,沿修复体边缘细菌积聚和变色的可能性越大,并产生继发性蛀牙。除了这些临床意义之外,患者的辨识能力很强,可以用舌头检测到0.30 ?m的粗糙度。美学修复应该模仿自然牙列的外观,应该有一个珐琅样的外观。对复合树脂的卓越美学需求的增加增加了对更有效和简单的抛光技术的需求。纳米复合材料的发展为复合树脂的抛光加工提供了新的前景。纳米复合材料声称具有改善光泽度、光学特性和减少磨损的优点。迄今为止,体外研究的结果一直是模棱两可的关于最有效和有效的抛光系统。由于复合树脂填充颗粒的大小、形状、组成和分布、树脂类型以及各种各样的精加工和抛光仪器的差异,不同的精加工和抛光仪器对表面粗糙度的影响是不同的。本文将回顾影响抛光技术的不同因素,以达到复合树脂修复体所需的抛光效果。

Differential diagnosis of orofacial pain is crucial, as the course of each process and its clinical management varies markedly. A case is illustrated here of trigeminal neuralgia in a 49-year-old Indian female whose complaint was initially diagnosed as dental pain leading to sequential extractions of her right mandibular and maxillary molars but with no pain abatement. Subsequent neurological assessment diagnosed her complaint as trigeminal neuralgia but pain remained poorly controlled even with high doses of carbamazepine and gabapentin. A dental referral and orthopantomographic examination revealed multifocal sclerotic masses in her jaws, suggestive of florid cemento-osseous dysplasia (FCOD). Right mandibular incisional biopsy confirmed the diagnosis. A decision was made to curette the right mandibular masses and lateralised the right inferior dental nerve. Follow-up disclosed considerable pain reduction. This case raises the issue as to whether the sclerotic bone masses in FCOD may have caused nerve compression which aggravated her neuralgic pain.
面部疼痛的鉴别诊断是至关重要的,因为每个过程的过程和临床处理有很大的不同。一例三叉神经痛的病例在这里是一个49岁的印度女性,她的投诉最初被诊断为牙痛导致连续拔除她的右下颌和上颌磨牙,但没有疼痛减轻。随后的神经学评估诊断为三叉神经痛,但即使使用高剂量卡马西平和加巴喷丁,疼痛仍然难以控制。牙科转诊和骨断层检查显示她的颌骨多灶性硬化肿块,提示骨质增生不良(FCOD)。右下颌骨切口活检证实了诊断。我们决定切除右侧下颌骨肿块并使右侧下牙神经偏侧。随访显示疼痛明显减轻。这个病例提出了一个问题,即FCOD的硬化骨团是否可能导致神经压迫,从而加重了神经痛。

Purpose of the study: The objective of this study was to investigate the existence of the golden proportion between the width of the maxillary anterior teeth of undergraduate dental students at University of Malaya. Materials and method: Standardised photographs of 100 dental students? smiles displaying only the lips and the teeth were captured. The images were transferred to a personal computer and the width of the maxillary anterior teeth was measured using an Image Analyzer (Leiqa QWin). Calculations were made according to the Theory of Golden Proportion. The data were statistically analysed using paired student T-test (?<0.05) Results: There was a statistically significant difference between the width of the right lateral incisors and 62% of the width of the right central incisors (only 19% subjects had their right lateral incisors in golden proportion with the width of their right central incisors, M=12.5%, F=20.3%, p=0.00). A significant difference also existed between the width of the right canines and 62% of the width of the right lateral incisors (only 17% of the subjects had the width of their canines in golden proportion with the width of their right lateral incisors, M=23.1%, F=12.2%, p=0.00). Conclusions: A significant difference existed between the right lateral incisors and 62% of the right central incisors, and between the right canines and 62% of the right lateral incisors in both male and female subjects. Mean maxillary anterior tooth proportion among the dental students were 0.70 for laterals to central incisors and 0.82 for canines to lateral incisors. The golden proportion is not a suitable method to relate the maxillary anterior tooth proportions in these Malaysian subjects.
研究目的:本研究的目的是调查马来亚大学牙科本科学生上颌前牙宽度之间是否存在黄金比例。材料和方法:100名牙科学生的标准化照片。只露出嘴唇和牙齿的微笑被捕捉了下来。将图像传输到个人计算机上,使用图像分析仪(Leiqa QWin)测量上颌前牙的宽度。根据黄金比例理论进行了计算。采用配对学生t检验对数据进行统计学分析(?<0.05)结果:右侧侧切牙宽度与右侧中切牙宽度的比例为62%,差异有统计学意义(仅19%的受试者右侧侧切牙与右侧中切牙宽度的比例为黄金比例,M=12.5%, F=20.3%, p=0.00)。右侧犬齿宽度与右侧侧门牙宽度的62%也存在显著差异(只有17%的受试者犬齿宽度与右侧侧门牙宽度达到黄金比例,M=23.1%, F=12.2%, p=0.00)。结论:在男性和女性受试者中,右侧侧切牙与62%的右侧中切牙、右侧犬齿与62%的右侧侧切牙之间存在显著差异。学生上颌前牙比例中,侧门牙与中门牙之比为0.70,犬齿与侧门牙之比为0.82。黄金比例不是一个合适的方法来联系上颌前牙比例在这些马来西亚受试者。

This study aimed to detect the presence of enterococci in the root canals of untreated and treated teeth with periapical disease and to compare this to their presence in the saliva and in the immediate surgical environment during root canal treatment. Using an aseptic technique, 33 samples were obtained from 27 untreated and 6 previously treated teeth associated with apical periodontitis. Reduced Transport Fluid (RTF) was used as transport medium. Saliva samples and areas in the surgical environment were also sampled. These were performed prior to chemo-mechanical debrjdement and obturation for every case. The saliva was diluted to 10- J and was plated on Bile Aesculin Azide (BEA) agar whereas the rest of the samples were plated on Bile Aesculin (BE) agar. These plates were then incubated aerobically at 37°C for 48 hours. All the colony types that blackened the agar were sub-cultured to obtain pure isolates and tested on 6.5% sodium chloride (NaCI). Growth on this medium was Gram stained for further confirmation of cell morphology. Gram positive cocci isolated from previous positive test were identified as enterococci. Enterococci were recovered from untreated cases only; from 2 teeth (in 2 patients) prior to chemo-mechanical debridement, from 3 teeth (in 3 patients) prior to obturation and I from saliva sample. A 'total of 5 samples from 5 different patients were positive for enteroco·cci. Sampling in theimmediate surgical environment revealed a low occurence in the range of3.0% (1/33) to 15_2% (5/33). In conclusion, the occurence of enterococci in patientsand the immediate surgical environment was low number.
本研究旨在检测未经治疗和治疗的根尖周疾病牙齿根管中肠球菌的存在,并将其与根管治疗期间唾液和手术环境中肠球菌的存在进行比较。使用无菌技术,从27个未治疗的和6个先前治疗的根尖牙周炎相关牙齿中获得33个样本。采用还原输运液(RTF)作为输运介质。唾液样本和手术环境的区域也被采样。这些都是在每个病例进行化学机械清除和封闭之前进行的。将唾液稀释至10- J后,涂于叠氮胆七叶皂苷(BEA)琼脂上,其余样品涂于胆七叶皂苷(BE)琼脂上。然后在37°C有氧孵育48小时。将所有使琼脂变黑的菌落类型进行继代培养,获得纯分离株,并在6.5%氯化钠(NaCI)上进行检测。革兰氏染色在培养基上生长,进一步确认细胞形态。从既往阳性试验中分离的革兰氏阳性球菌被鉴定为肠球菌。仅在未经治疗的病例中发现肠球菌;2例患者化学机械清创前的2颗牙齿,3例患者封闭前的3颗牙齿,1例患者唾液样本。5例患者共5份标本肠球菌·cci阳性。直接手术环境的抽样显示低发生率在3.0%(1/33)至152%(5/33)之间。综上所述,肠球菌在患者和即刻手术环境中的发生率较低。

The objectives of this study were to assess the practice of molar root canal treatment (RCT) among general dental practitioners (GDPs), confidence level of GDPs in performing molar RCT and to identify factors that influence their confidence in managing molar RCI. One hundred questionnaires were distributed to GDPs in Kuala Lumpur and Selangor. Fifty questionnaires were delivered by mail and the remaining fifty were hand-delivered. All data was coded and verified. Fifty six OOPs rcsponded to the questionnaires. Only forty five questionnaires were accepted (n=45) as eleven OOPs had never performed molar RCI. Most of the OOPs followed the standard quality guidelines while performing molar RCT except for vitality testing (36.4%) and rubber dam usage (27.3%). In this study, 100% of the GDPs were confident in making diagnosis of perinidicular diseases and 95.4% were confident in performing molar RCT from history taking until obturation. Patients' tolerance and availability of instruments and materials (97.7%) were two factors that most influence the GDPs' confidence level. The least influcncing factor was undergraduate training (78.1 %). Attending seminars and lectures on endodontic, large number of molar teeth treated for ReT, patLents' affordability to pay for RCT and postgraduate training also influencc GDPs' confidence to a certain degree. From this study, it can be concluded that majority of OOPs complied standard quality guidelines except for vitality testing and rubber dam usage. Most of them were confident in performing molar RCT and were greatly influenced by the availability or"instruments and materials in their clinic and patients' tolerance in receiving molar RCI.
本研究的目的是评估普通牙科医生(gdp)进行磨牙根管治疗(RCT)的做法,gdp进行磨牙RCT的置信水平,并确定影响他们管理磨牙RCI信心的因素。向吉隆坡和雪兰莪的gdp发放了100份问卷。其中50份问卷通过邮寄的方式发放,剩下的50份则是手工发放。所有数据都经过编码和验证。56名受访者回答了调查问卷。只有45份问卷被接受(n=45),因为11名OOPs从未进行过臼齿RCI。除活力测试(36.4%)和橡胶坝使用(27.3%)外,大多数OOPs在进行磨牙RCT时符合标准质量准则。在本研究中,100%的gdp对针尖周围疾病的诊断有信心,95.4%的gdp对从病史到闭孔进行磨牙RCT有信心。患者的耐受性和器械和材料的可获得性(97.7%)是影响gdp置信水平的两个最重要因素。影响因素最少的是本科教育(78.1%)。参加牙髓学方面的研讨会和讲座、接受ReT治疗的磨牙数量较多、患者支付RCT费用的能力和研究生培训的能力也在一定程度上影响了gdp的信心。从本研究可以看出,除了活力测试和橡胶坝使用外,大多数OOPs符合标准质量准则。他们大多数对进行磨牙RCT有信心,并且在很大程度上受到临床可用的“仪器和材料”以及患者接受磨牙RCI的耐受性的影响。

Mini-implant Supported Over Denture in a Patient with Down Syndrome: A Case Report 唐氏综合征患者的迷你种植支撑覆盖义齿:一例报告
Pub Date : 2009-12-31 DOI: 10.22452/ADUM.VOL16NO1.6
Rathna Devi VaithiIingam, R. Mahmood
The presence of macroglossia, a tendency towards poor cooperation and the inability to adapt to compl~te dental prostheses due to motor and mental deficiencies makes the oral rehabilitation of Down Syndrome patients difficult. This article reports on the use of mini implant supported overdenture to rehabilitate a Down Syndrome patient who had difficulty adapting to his new mandibular complete denture. The patient's ability to cooperate during treatment as well as the maintenance of an optimal oral hygiene practice enabled mini-implants to be inserted and maintained 20 months post insertion as evidenced by clinical and radiological findings. To the author's knowledge, this is the first reporting of a successful mini implant supported overdenture in a Down Syndrome patient.
由于运动和智力缺陷导致的大舌缺失、合作能力差的倾向以及无法适应完成义齿,使得唐氏综合征患者的口腔康复变得困难。这篇文章报告了使用微型种植支撑覆盖义齿来修复唐氏综合症患者谁有困难适应他的新的下颌全口义齿。临床和放射学结果证明,患者在治疗期间的合作能力以及保持最佳口腔卫生习惯使微型种植体得以植入并在植入后维持20个月。据作者所知,这是首次报道在唐氏综合征患者中成功使用迷你种植支撑覆盖义齿。
