The aim of this study was to obtain data of medical emergencies at the non-hospital based private dental practices in Petaling district of Selangor, Malaysia. Ninety out of 281 identified main practitioners of non-hospital based private dental practices had agreed to participate. A standardised questionnaire forms consisting of four parts including demographic data, emergency equipment and drugs available, occurrence of medical emergencies and training of dental practitioners. All data retrieved were analysed using the Statistical Programme for Social Science (SPSS) version 22.0 (SPSS Inc., 1999). Some of the clinics (28.9%) had reported experiencing medical emergencies events. The most common emergency event noted was syncope (42.2%), followed by hypoglycaemia (27.7%). Majority of the events occurred in the dental surgery room (84.3%), after completion of treatment (31.3%) and were associated with dental extraction procedures (61.4%). Only nine of the clinics (3.3%) were equipped with emergency trolley and none were prepared with a defibrillator or automated external defibrillator (AED). It was also found that 32.3% of all clinics do not have any emergency drugs. All of the practitioners received basic life support training before graduation and 52.2% received supplementary training after graduation. In conclusion, emergency medical events do occur, but majority of dental practices involved in this study were not well equipped to manage these emergencies. It is important to have a standardised national guideline to ensure a safe and well-prepared dental setting during any adverse medical events.
本研究的目的是获取马来西亚雪兰莪州八打灵区非医院私人牙科诊所的医疗紧急情况数据。281名已确定的非医院私人牙科诊所的主要从业者中,有90人同意参与。标准化调查表由四部分组成,包括人口统计数据、可用的急救设备和药物、医疗紧急情况的发生和牙科医生的培训。使用社会科学统计程序(SPSS)22.0版(SPSS股份有限公司,1999)对检索到的所有数据进行分析。一些诊所(28.9%)曾报告发生过医疗紧急事件。最常见的紧急事件是晕厥(42.2%),其次是低血糖(27.7%)。大多数事件发生在牙科手术室(84.3%),治疗结束后(31.3%),并与拔牙程序有关(61.4%)。只有9家诊所(3.3%)配备了急救车,没有一家配备除颤器或自动体外除颤器(AED)。调查还发现,32.3%的诊所没有任何急救药物。所有从业者在毕业前都接受了基本的生命支持培训,52.2%的人在毕业后接受了补充培训。总之,紧急医疗事件确实会发生,但本研究中涉及的大多数牙科诊所都没有做好应对这些紧急情况的准备。重要的是要有一个标准化的国家指南,以确保在任何不良医疗事件中都有一个安全且准备充分的牙科环境。

This study aimed to determine the prevalence and severity of chronic periodontitis (CP) and the relationship between periodontal status and dry mouth condition in patients with type 2 diabetes mellitus (T2DM). A cross-sectional study was conducted on 66 controlled T2DM patients, determined by HbA1c level ≤ 9%. Plaque index (PI), gingival index (GI), periodontal pocket depth (PPD), and clinical attachment loss (CAL) were recorded. Subjects were given questionnaire for self-evaluation of dry mouth followed by collection of saliva. Data were analysed using SPSS version 22.0. Results showed that the prevalence of CP was 93.9% with severity ranging from mild (41.9%), moderate (30.6%), to severe (27.5%). Most subjects (74.2%) had normal stimulated salivary flow rate although 15.9% reported having less saliva. There was no significant association between periodontal parameters and salivary flow rate. In conclusion, T2DM patients exhibited high prevalence of CP despite having controlled glycaemic status. Dry mouth condition was not a common symptom and was also not associated with periodontitis. To ensure appropriate management of diabetics, collaboration between medical colleagues and dental practitioners is important to control progression of periodontal disease.
本研究旨在确定2型糖尿病(T2DM)患者慢性牙周炎(CP)的患病率和严重程度,以及牙周状况与口干状况之间的关系。对66名对照T2DM患者进行了横断面研究,其HbA1c水平≤9%。记录牙菌斑指数(PI)、牙龈指数(GI)、牙周袋深度(PPD)和临床附着丧失(CAL)。对受试者进行口腔干燥自评问卷调查,然后收集唾液。使用SPSS 22.0版对数据进行分析。结果显示,CP的患病率为93.9%,严重程度从轻度(41.9%)、中度(30.6%)到重度(27.5%)不等。大多数受试者(74.2%)的刺激唾液流量正常,但15.9%的受试者报告唾液较少。牙周参数和唾液流速之间没有显著的相关性。总之,尽管血糖状况得到控制,但T2DM患者表现出高CP患病率。口腔干燥不是常见症状,也与牙周炎无关。为了确保对糖尿病患者进行适当的管理,医学同事和牙科医生之间的合作对于控制牙周病的进展非常重要。

Work environment in dentistry benefits the right-handed dental practitioners. This situation requires the left-handers to work in an adjusted position causing them discomfort and inconvenience. The aim of this study was to explore the experiences of the identified left-handed undergraduate dental students in Faculty of Dentistry, Universiti Sains Islam Malaysia (USIM) in performing dental procedures. The first phase of the study was to determine handedness of the students using the Edinburgh Handedness Inventory Questionnaire that was distributed to all the dental students. This was followed by a qualitative study using the phenomenology approach. Semi-structured interviews were conducted on left-handed students to determine their perceptions on left-handedness in performing dental procedures. The number of students interviewed was based on attainment of the saturation point. The interview was recorded and transcribed verbatim. The transcripts were analysed through coding, categorising and grouping responses into themes. Prevalence of left-handedness in this faculty was 7%. The participants were not aware of the right-handed situation when they enrolled in the faculty. This situation gave rise to psychological impact such as anxiety and stress. Although some participants were able to use their right hand for certain procedures, the dominant hand continued to be their preference. The difficulties encountered when using the non-dominant hand were grip-strength, angulation and positioning of the instruments. Dental procedures in periodontology (such as scaling, root debridement) and oral surgery (tooth extraction, incision and suturing) were found to be very challenging. They experienced muscle fatigue, reduced precision and prolonged time to complete the dental procedures. They felt that they should be given more time to adapt using the right hand under the tutelage of left-handed faculty members. Left-handed dental students faced difficulties in adapting to the right-handed situation and affect their effectiveness and efficiency. Specific activities need to be designed for left-handers to adapt to the situation under the guidance of left-handed faculty members.
牙科的工作环境有利于惯用右手的牙科医生。这种情况需要左撇子在调整好的位置上工作,这会给他们带来不适和不便。本研究的目的是探索马来西亚伊斯兰大学牙科学院(USIM)已确定的左撇子本科生在进行牙科手术方面的经验。研究的第一阶段是使用分发给所有牙科学生的爱丁堡惯用手问卷来确定学生的惯用手情况。随后采用现象学方法进行了定性研究。对左撇子学生进行了半结构化访谈,以确定他们在进行牙科手术时对左撇子的看法。受访的学生人数是以达到饱和点为基础的。采访被逐字记录下来。转录本通过编码、分类和将反应分组为主题进行分析。该学院的左撇子患病率为7%。参与者在进入学院时并没有意识到右手的情况。这种情况引发了焦虑和压力等心理影响。尽管一些参与者能够在某些程序中使用右手,但占主导地位的手仍然是他们的偏好。使用非优势手时遇到的困难是握力、角度和器械的定位。牙周病学(如洁牙、牙根清创术)和口腔外科(拔牙、切口和缝合)的牙科手术非常具有挑战性。他们经历了肌肉疲劳、精度下降和完成牙科手术的时间延长。他们觉得应该给他们更多的时间在左撇子教员的指导下适应使用右手。左撇子牙科学生在适应惯用右手的情况方面面临困难,并影响了他们的有效性和效率。需要为左撇子设计具体的活动,以便在左撇子教员的指导下适应这种情况。

For decades, coconut oil was reported to possess a broad spectrum of antimicrobial activity due to its abundant fatty acid’s contents. Streptococcus mutans (S. mutans) has been strongly implicated as the main etiological factor in dental caries. Regardless of the ongoing medical advances, the therapeutic resources for dental caries remain ineffectual, and this has led to renewed interest in using virgin coconut oil (VCO) as a possible choice for dental caries control. In this study, the ability of VCO and activated virgin coconut oil (AVCO) combatting cariogenic S. mutans ATCC 25175 has been evaluated. Fatty acids contents were compared through Gas Chromatography-Mass Spectrum (GC-MS) analysis, and their antimicrobial activity was determined using disc diffusion and minimum inhibitory concentration (MIC) test. From the GC-MS analysis, AVCO (59%) was found to have a slightly higher medium-chain fatty acids (MCFA) as compared to VCO (54.1%), and the long-chain fatty acids (LCFA) contents in VCO (45.9%) was found to be higher than AVCO (41%). Interestingly, S. mutans ATCC 25175 was found to be susceptible towards AVCO (MIC: 6.24 mg/ml) and resistance towards VCO in vitro. The excellent antimicrobial activity of AVCO as a result from (i) the release of individuals fatty acids after activation of virgin coconut oil by lipase digestion and (ii) the present of MCFA and LCFA that are significant in antimicrobial activity. Further study can be designed to specifically examine the activity of individuals fatty acids present in oils against S.mutans virulence genes/protein using molecular dynamic assessment.
几十年来,椰子油因其富含脂肪酸而被报道具有广谱抗菌活性。变形链球菌(S.mutans)是龋齿的主要致病因素。尽管目前医学取得了进展,但龋齿的治疗资源仍然无效,这导致人们对使用初榨椰子油(VCO)作为控制龋齿的可能选择重新产生了兴趣。在本研究中,评估了VCO和活性初榨椰子油(AVCO)对抗致龋变形链球菌ATCC 25175的能力。采用气相色谱-质谱(GC-MS)分析法对脂肪酸含量进行比较,并采用纸片扩散法和最小抑菌浓度(MIC)法测定其抗菌活性。从GC-MS分析中发现,与VCO(54.1%)相比,AVCO(59%)具有略高的中链脂肪酸(MCFA),并且VCO中的长链脂肪酸含量(45.9%)高于AVCO(41%)。有趣的是,变异链球菌ATCC 25175在体外对AVCO敏感(MIC:6.24mg/ml),对VCO耐药。AVCO优异的抗微生物活性是由于(i)通过脂肪酶消化活化初榨椰子油后个体脂肪酸的释放和(ii)抗微生物活性显著的MCFA和LCFA的存在。可以设计进一步的研究,使用分子动力学评估来专门检测油中存在的个体脂肪酸对变异链球菌毒力基因/蛋白质的活性。
