This retrospective study aimed to evaluate patterns of comprehensive dental treatment under general anaesthesia (GA) for healthy children in Universiti Teknologi MARA, Malaysia. The treatment records of healthy paediatric patients who received dental treatment under GA from February 2017 to January 2021 were reviewed. The patients were divided into two groups: (1) less than 6 years old and (2) 6 to 16 years old. Patients’ characteristics were summarised using descriptive statistics while an independent t-test was applied to investigate the influence of “age group” on treatment duration, number of procedures and use of various restorative materials. A total of 125 paediatric patients (67 boys and 58 girls) were included. The patients’ mean age at the time they underwent GA was 5.77 ± 1.94 years old and the average duration of dental treatment was 62.58 minutes. There was a significant difference in the duration of treatment between the two age groups (p < 0.05). Tooth extraction was the most dental procedure performed (63.31%). The 6 to 16 years old group had a significantly shorter treatment duration (p < 0.05). However, no significant differences were found in all procedures (extraction, restoration, preventive and pulp therapy) and the utilisation of composite, glass ionomer cement (GIC) and compomer in both groups. The use of stainless steel crown (SSC) restorations was significantly higher in the less than six years old group (p < 0.05). Most of the dental procedures performed under GA on healthy children were extraction procedures. Children less than six years of old had a longer treatment duration under GA. Composite restorations and SSC were more frequently used in primary dentition.
这项回顾性研究旨在评估马来西亚马拉科技大学健康儿童在全身麻醉(GA)下的综合牙科治疗模式。回顾了2017年2月至2021年1月接受GA牙科治疗的健康儿科患者的治疗记录。将患者分为两组:(1)6岁以下和(2)6-16岁。使用描述性统计对患者的特征进行总结,同时使用独立的t检验来调查“年龄组”对治疗持续时间、手术次数和各种恢复材料使用的影响。共纳入125名儿科患者(67名男孩和58名女孩)。患者接受GA时的平均年龄为5.77±1.94岁,牙科治疗的平均持续时间为62.58分钟。两个年龄组的治疗时间有显著差异(p<0.05)。拔牙是进行最多的牙科手术(63.31%)。6-16岁组的治疗持续时间明显更短(p<0.05),两组在所有程序(提取、修复、预防和牙髓治疗)以及复合材料、玻璃离聚物水泥(GIC)和复合物的使用方面均未发现显著差异。不到6岁的儿童使用不锈钢冠(SSC)修复体的比例明显较高(p<0.05)。在GA下对健康儿童进行的大多数牙科手术都是拔牙手术。六岁以下的儿童在GA下的治疗时间更长。复合修复体和SSC在乳牙列中更常见。

High viscous glass ionomer cement (HVGIC) was recently developed for atraumatic restorative treatment (ART). However, its moisture sensitivity remains a limitation thus protective coating application is recommended. This study investigated the effect of resin coating on the surface roughness and microhardness of two HVGICs (Riva Self Cure HVGIC [RV] and Equia® Forte Fil [EQ]) conditioned in food-simulating liquids (FSLs). Fifty standard disc-shaped samples were fabricated using customised stainless-steel mould (10 × 2 mm). Coating was applied on top surface of all samples and subsequently divided into five groups: air (control), distilled water, 0.02 N citric acid, heptane and 50% ethanol-water solution. The samples were conditioned in FSLs at 37°C for seven days. Subsequently, the surface roughness and microhardness of samples were measured using optical profilometry and microhardness tester, respectively. SEM analysis was done for qualitative observation of surface morphological changes. Data were analysed using one-way ANOVA, two-way ANOVA and posthoc Tukey’s test (α = 0.05). Interestingly, the results revealed that surface roughness was significantly influenced by FSLs immersion, presence of coating and the materials itself (p < 0.001). The lowest surface roughness was found on control coated samples: RV (50.98±4.25) nm and EQ (62.77±3.92) nm, while the highest values seen on uncoated surfaces in citric acid: RV (505.26±31.10) nm and EQ (350.33±15.36) nm. RV samples had the lowest microhardness of 54.97±2.48 Vickers hardness number (VHN) post-immersion in citric acid. In conclusion, with the exception of RV conditioned in heptane and ethanol, the uncoated HVGICs generally had higher surface roughness than the coated HVGICs. HVGICs conditioned in citric acid showed the most significant increase in surface roughness and reduction in microhardness.
高粘度玻璃离聚物水泥(HVGIC)是最近开发的一种用于无创伤修复治疗(ART)的水泥。然而,其水分敏感性仍然是一个限制,因此建议使用保护涂层。本研究研究了树脂涂层对两种在食品模拟液体(FSL)中处理的HVGIC(Riva Self Cure HVGIC[RV]和Equia®Forte Fil[EQ])表面粗糙度和显微硬度的影响。使用定制的不锈钢模具(10×2mm)制作了50个标准圆盘状样品。将涂层涂覆在所有样品的顶面上,随后分为五组:空气(对照)、蒸馏水、0.02N柠檬酸、庚烷和50%乙醇水溶液。样品在37°C的FSL中处理7天。随后,分别使用光学轮廓术和显微硬度计测量了样品的表面粗糙度和显微硬度。扫描电镜分析对表面形态变化进行了定性观察。使用单因素方差分析、双因素方差分析和posthoc-Tukey检验(α=0.05)对数据进行分析。有趣的是,结果显示表面粗糙度受到FSL浸渍、涂层存在和材料本身的显著影响(p<0.001)。对照涂层样品的表面粗糙度最低:RV(50.98±4.25)nm和EQ(62.77±3.92)nm,而在柠檬酸的未涂覆表面上观察到的最高值:RV(505.26±31.10)nm和EQ(350.33±15.36)nm。RV样品在柠檬酸中浸泡后的显微硬度最低,为54.97±2.48维氏硬度值(VHN)。总之,除了在庚烷和乙醇中调节的RV外,未涂覆的HVGIC通常比涂覆的HVGC具有更高的表面粗糙度。在柠檬酸中处理的HVGICs显示出表面粗糙度的最显著增加和显微硬度的降低。

Dental caries is a commonly progressive disease that proceeds through various degrees of severity that a dentist can detect. The aims of the in vivo study were to assess the accuracy of the individual model (near-infrared light transillumination [NILT] device, visual and radiographic examinations) in detecting occlusal caries, and to evaluate the performance of visual and NILT device combination for occlusal caries detection in deciding the treatment options. Fifty-two non-cavitated occlusal surfaces from 16 patients were assessed with three different diagnostic devices in random order. Identified lesions were prepared and validated. Logistic regression analysis was performed for each method. The sensitivity and specificity values for each method and the combined models were statistically measured using RStudio version 0.97.551. At the enamel level, visual detection was the most sensitive method (0.88), while NILT was the most specific (0.93). NILT scored the highest for sensitivity (0.93) at the dentine level and visual detection scored the highest for specificity (0.88). Visual detection + NILT model was significantly better (p = 0.04) compared to visual detection or NILT alone (df = 1). The visual-NILT combination is a superior model in detecting occlusal caries on permanent teeth. The model provided surplus value in caries detection hence improving the treatment decision-making in occlusal surfaces.
龋齿是一种常见的进行性疾病,其严重程度各不相同,牙医都能检测到。体内研究的目的是评估个体模型(近红外光透射[NILT]装置,视觉和放射检查)检测咬合龋齿的准确性,并评估视觉和NILT装置组合检测咬合龋齿的性能,以决定治疗方案。对16例患者的52个非空化咬合面采用三种不同的诊断设备随机排序进行评估。准备并验证已确定的病变。对每种方法进行Logistic回归分析。采用RStudio 0.97.551版本统计各方法及组合模型的敏感性和特异性值。在牙釉质水平,目测是最敏感的方法(0.88),而NILT是最特异的方法(0.93)。在牙本质水平上,NILT的灵敏度最高(0.93),视觉检测的特异性最高(0.88)。视觉检测+ NILT模型明显优于单纯视觉检测或NILT模型(p = 0.04) (df = 1)。视觉-NILT联合检测恒牙合龋是较好的模型。该模型为龋病检测提供了剩余价值,从而改善了牙合面治疗决策。

Orthodontic treatments have been described as a risk factor for the development of gingival recessions. This descriptive and cross-sectional study was performed to evaluate the alveolar bone morphotype of the upper and lower anterior of 33 orthodontic treatment of candidate patients. The images were obtained from a high-resolution cone beam computerised tomography. Then, the thickness of the alveolar bone plate of teeth was measured in six levels, recording the presence of dehiscences and fenestrations. A total of 2,334 sites were evaluated. The average thickness of the maxillary alveolar bone at the buccal surface was 0.70, 0.62 and 1.43 mm at the cervical, middle and apical levels, respectively, while in the mandibular teeth it was 0.53, 0.50 and 2.96 mm. At the palatal and lingual surfaces, the bone was thicker than the buccal except at the apical level of the mandible. Most of the examined sites were measured less than 1 mm (n = 1,235, 52.9%), associated with high prevalence of bone dehiscences (57.6%) and fenestrations (33.3%), particularly in skeletal Class III patients. The observed bone morphotype involved a high vulnerability to bone resorption, and the subsequent gingival recession occurrence, face to orthodontic movements.
正畸治疗已被描述为牙龈退缩发展的风险因素。这项描述性和横断面研究旨在评估33名候选患者正畸治疗前上下牙槽骨形态类型。这些图像是从高分辨率锥束计算机断层扫描中获得的。然后,在六个层面上测量牙齿牙槽骨板的厚度,记录是否存在开裂和开窗。共评估了2334个地点。口腔表面上颌牙槽骨的平均厚度在颈、中和根尖水平分别为0.70、0.62和1.43 mm,而在下颌牙齿中为0.53、0.50和2.96 mm。在腭和舌表面,除下颌根尖水平外,骨比口腔厚。大多数检查部位的测量值小于1毫米(n=1235,52.9%),与骨折(57.6%)和开窗(33.3%)的高患病率有关,尤其是在骨骼III级患者中。观察到的骨形态类型涉及骨吸收的高度脆弱性,以及随后发生的牙龈退缩,面对正畸运动。

Education worldwide has been conducted in the traditional face-to-face classroom teaching style for ages, and this includes the education in dentistry. Since the introduction of online education and distance learning, teaching institutions have gradually made e-learning an integral part of teaching and learning activities. With the emergence of COVID-19 pandemic and closure of teaching institutions worldwide, the faculty of dentistry is amongst the many that were forced to leap onto the online education field abruptly. There is a sudden need for educators to resort to online teaching and e-learning becomes an essential tool to be developed as an alternative to traditional education methods. This article serves as a review to explore and discuss the common concerns and institutional readiness in delivering e-learning and review the methods currently utilised during this time of crisis.
多年来,世界各地的教育都是以传统的面对面课堂教学方式进行的,其中包括牙科教育。自从引入在线教育和远程学习以来,教学机构逐渐将电子学习作为教学活动的组成部分。随着新冠肺炎疫情的出现和全球教学机构的关闭,牙科学院是许多被迫突然进入在线教育领域的教师之一。教育工作者突然需要求助于在线教学,电子学习成为一种替代传统教育方法的重要工具。本文旨在探讨和讨论提供电子学习的共同问题和机构准备情况,并回顾当前危机时期使用的方法。

The present study aimed to evaluate the surface electromyography (sEMG) activity of the masseter muscles in patients with a history of temporomandibular joint disorder (TMJD) who received orthodontic treatment. In total, 22 participants aged 18–35 years old were included in this study. They were divided into the control group (patients without a history of TMJD [n = 11]) and the test group (those with a history of TMJD [n = 11]). Each participant underwent sEMG of the right and left masseter muscles at 5-s maximum voluntary contraction (MVC). Results showed that the TMJD group had a lower sEMG activity of masseter muscles at MVC than the non-TMJD group. However, the differences were not statistically significant (p > 0.05, t-test). The Spearman’s correlation coefficient test revealed a weak negative correlation between muscle activity on sEMG and history of TMJD (p > 0.05). In conclusion, orthodontically treated patients in TMJD group have reduced masseter muscle activity during MVC, compare to the non-TMJD group.
本研究旨在评估有颞下颌关节紊乱(TMJD)病史并接受正畸治疗的患者咬肌表面肌电图(sEMG)活动。本研究共纳入了22名年龄在18-35岁之间的参与者。将其分为对照组(无TMJD病史的患者[n = 11])和试验组(有TMJD病史的患者[n = 11])。每个参与者在5秒最大随意收缩(MVC)时对左右咬肌进行肌电图。结果表明,TMJD组面肌电信号活动咬肌的肌肉在MVC低于non-TMJD组。但差异无统计学意义(p < 0.05, t检验)。Spearman相关系数检验显示肌电活动与颞下颌关节病病史呈弱负相关(p < 0.05)。综上所述,与非TMJD组相比,TMJD组正畸治疗的患者在MVC期间咬肌活动减少。

The first dental examination is a major step that is affected by many factors and determines the dental treatment process. The main objective of this study was to evaluate the association of child temperament with child dental anxiety, parental dental anxiety, dental behaviour and dental caries. The study consisted of 100 children aged 3 to 6 who were attending their first dental examination and their accompanying parents. The Facial Image Scale (FIS), Frankl’s Behaviour Scale (FBS), Corah’s Dental Anxiety Scale (CDAS) and the Short Temperament Scale for Children (STSC) were used for assessment. The DMFT (decayed, missing and filled teeth) score of each child was recorded. Children who exhibited negative behaviour on the FBS had the highest rhythmicity scores (p = 0.008). The mean DMFT score of children in the rhythmicity temperamental dimension was relatively high (p = 0.008). The parents of children defined as negative on the FBS had high dental anxiety levels on CDAS (p < 0.001). Children whose parents had higher dental anxiety levels showed higher dental anxiety (p = 0.007). The success rate of dental treatment procedures may be increased by improving dentists’ knowledge of dental anxiety related to the child’s temperament and integrating parental support to reduce dental anxiety.
第一次牙科检查是受多种因素影响的重要步骤,决定了牙科治疗过程。本研究的主要目的是评估儿童气质与儿童牙科焦虑、父母牙科焦虑、牙科行为和龋齿的关系。这项研究由100名3至6岁的儿童和他们的陪同父母组成,他们正在参加第一次牙科检查。采用面部图像量表(FIS)、弗兰克尔行为量表(FBS)、科拉口腔焦虑量表(CDAS)和儿童短气质量表(STSC)进行评估。记录每个孩子的DMFT(蛀牙、缺牙和补牙)评分。在FBS上表现出消极行为的儿童的节律性得分最高(p=0.008)。儿童在节律性-气质维度上的平均DMFT得分相对较高(p=0.008焦虑(p=0.007)。牙科治疗程序的成功率可以通过提高牙医对与儿童气质相关的牙科焦虑的认识,并整合父母的支持来减少牙科焦虑来提高。

Educational landscape has changed drastically over the past decades with the integration of technology to support the role of educators. The objectives of this study were to examine the use of social media application among dental students and to investigate significant demographic variables with regard to social media use for academic purposes. All dental students across all academic years were invited to participate in a self-administered questionnaire (content validated, pre-tested) survey conducted online via Google Forms. Overall response rate was 67.8%. Of the 244 respondents, 99.1% owned smartphones, with a majority of them were iPhone and Android users. Notably, 91.4% of the respondents had access to internet data via a third generation (3G) mobile carrier and WiFi connection. A majority of the respondents (97.1%) used social media to communicate or connect with friends whereas 5.7% of them used it for business purposes. There was no significant association between gender, year of study and type of internet access with the mean of social media usage for academic purposes (p > 0.05). Most of the respondents preferred YouTube (74.6%) and Google (73.7%) for seeking information in their study. In conclusion, we found that majority of respondents had acknowledged the importance of social media in education. Our findings suggest the potential value of integrating social media in teaching and learning activities to enhance students’ learning experience.
在过去的几十年里,随着技术的融合,教育工作者的角色发生了巨大的变化。本研究的目的是调查牙科学生对社交媒体应用的使用情况,并调查与学术目的社交媒体使用有关的重要人口统计学变量。所有学年的牙科学生都被邀请参加一份自我管理的问卷调查(内容经过验证,预先测试),通过谷歌表格进行在线调查。总有效率为67.8%。在244名受访者中,99.1%的人拥有智能手机,其中大多数是iPhone和Android用户。值得注意的是,91.4%的受访者通过第三代(3G)移动运营商和WiFi连接访问互联网数据。大多数受访者(97.1%)使用社交媒体与朋友沟通或联系,而5.7%的受访者将其用于商业目的。性别、学习年限和互联网接入类型与学术目的社交媒体使用的平均值之间没有显著关联(p < 0.05)。大多数被调查者在学习中更喜欢YouTube(74.6%)和谷歌(73.7%)来寻找信息。综上所述,我们发现大多数受访者都承认社交媒体在教育中的重要性。我们的研究结果表明,将社交媒体整合到教学和学习活动中,可以提高学生的学习体验。

Thalassemia is an inherited disorder that involves abnormal haemoglobin formation. This cross-sectional study with universal sampling was conducted from May 2018 to January 2019 to evaluate the oral health status of children with thalassaemia. The sample consisted of 54 transfusion-dependent patients between the ages of 3–17 years old, who were registered at the paediatric day-care centre of Hospital Melaka. Oral health status was evaluated which included soft tissue examination, recording of dental caries, malocclusion and oral hygiene status of the children, while their parents answered a pre-validated self-administered questionnaire on sociodemographic and oral health practices and attitudes. The mean deft (decayed, exfoliated and filled teeth) among the 3–5 years old was 6.71±6.07. The mean DMFT (decayed, missing and filled teeth) was 3.00±3.94 among the 13–17 years old and 1.12±1.42 among the 6–12 years old. Most of the 3–5 years old children exhibited good oral hygiene (71.4%). Dentofacial findings among the 3–5 years old were increased overjet (35.7%) and open bite (28.6%) predominantly. Fractured teeth (69.2%), increased overjet (46.2%) and discolouration (23.1%) were the common dentofacial findings among the 6–12 years old while increased overjet (71.4%), soft tissue lesions (57.1%) and posterior crossbite (28.6%) were seen among the 13–17 years old. In this cohort of children with thalassaemia, the prevalence of dental caries was high in preschool children and older children.
地中海贫血是一种遗传性疾病,涉及异常的血红蛋白形成。这项普遍抽样的横断面研究于2018年5月至2019年1月进行,旨在评估地中海贫血儿童的口腔健康状况。样本包括54名年龄在3-17岁之间的输血依赖患者,他们在马六甲医院的儿科日托中心登记。对儿童的口腔健康状况进行了评估,包括软组织检查、龋齿记录、错牙合和口腔卫生状况,而他们的父母则回答了一份预先验证的关于社会人口和口腔健康实践和态度的自填问卷。3-5岁儿童的平均灵巧度(蛀牙、脱落牙和填充牙)为6.71±6.07。13-17岁的平均DMFT(蛀牙、缺牙和补牙)为3.00±3.94,6-12岁的平均为1.12±1.42。大多数3-5岁儿童表现出良好的口腔卫生(71.4%)。3-5岁儿童的口腔检查结果主要是过度咬合(35.7%)和开放咬合(28.6%)。在6-12岁的儿童中,牙齿骨折(69.2%)、牙冠增加(46.2%)和变色(23.1%)是常见的牙面表现,而在13-17岁的儿童则出现牙冠增多(71.4%)、软组织病变(57.1%)和后反牙(28.6%)。在这组地中海贫血儿童中,学龄前儿童和年龄较大儿童的龋齿患病率较高。

The study aimed to quantify the impact of lockdown during the COVID-19 pandemic on new case referrals to the Oral and Maxillofacial Surgery (OMS) service. The researchers retrospectively reviewed all new referrals received during a government-imposed 47-day lockdown period and a similar period pre-lockdown as a control group. The main outcome was the differences in the number of new case referrals between the two periods. The contributing clinical and demographic factors were also explored. Appropriate bivariate statistics were computed and the level of significance was set at 0.05 for all tests. A total of 309 referrals were received during the study period. There was a reduction of new referrals due to the lockdown from five to two cases per day. There was a statistically significant reduction of cases referred from outpatient and emergency departments. There was also a statistically significant difference with regard to home address distance to the centre. Medically compromised and orofacial infection referrals were not affected by lockdown. The lockdown imposed due to the pandemic has significantly impacted the pattern of new OMS referrals. Referrals for orofacial infections, the medically compromised and inpatients were minimally affected by lockdown.
该研究旨在量化新冠肺炎大流行期间封锁对口腔颌面部外科(OMS)新病例转诊的影响。研究人员回顾性地审查了在政府实施的47天封锁期间和封锁前类似时期作为对照组收到的所有新转诊。主要结果是两个时期的新病例转诊数量存在差异。还探讨了影响临床和人口统计学的因素。计算适当的双变量统计数据,并将所有测试的显著性水平设置为0.05。研究期间共收到309例转诊病例。由于封锁,新的转诊病例从每天5例减少到每天2例。从门诊和急诊科转诊的病例在统计上显著减少。家庭住址与中心的距离也存在统计学上的显著差异。医疗受损和口腔面部感染转诊没有受到封锁的影响。由于疫情而实施的封锁对新的OMS转诊模式产生了重大影响。口腔面部感染的转诊患者、身体受损的患者和住院患者受封锁影响最小。
