ABSTRACT Dry eye syndrome (DES) is a prevalent ocular condition characterized by insufficient tear production or excessive tear evaporation, leading to discomfort and visual disturbances. Omega-3 fatty acids have been proposed as a potential therapeutic intervention for DES due to their anti-inflammatory and lipid modulation properties. Cultured human corneal epithelial cells were exposed to various concentrations of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for 72 h. Cell viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, while inflammatory cytokine levels (interleukin-6 (IL-6), interleukin-8 (IL-8)) and lipid profile (measured by lipid staining) were evaluated using enzyme-linked immunosorbent assay. Untreated cells served as controls for comparison. Omega-3 fatty acid supplementation demonstrated a dose-dependent increase in cell viability compared to untreated cells. At optimal concentrations, EPA and DHA significantly enhanced cell viability by 30% and 35%, respectively (P < 0.05). Moreover, omega-3 fatty acid supplementation led to a significant reduction in inflammatory cytokine levels, with a 50% decrease in IL-6 and IL-8 secretion compared to untreated cells (P < 0.01). Additionally, lipid staining revealed improved lipid profile and organization in corneal epithelial cells following omega-3 fatty acid supplementation, indicative of enhanced tear film stability. In vitro findings suggest that omega-3 fatty acid supplementation exerts beneficial effects on cellular markers associated with DES.
摘要 干眼症(DES)是一种常见的眼部疾病,其特点是泪液分泌不足或过度蒸发,从而导致不适和视觉障碍。欧米茄-3 脂肪酸具有抗炎和调节脂质的特性,因此被认为是干眼症的潜在治疗干预措施。 将培养的人类角膜上皮细胞暴露于不同浓度的欧米伽-3 脂肪酸(包括二十碳五烯酸 (EPA) 和二十二碳六烯酸 (DHA))中 72 小时。细胞活力用 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑测定法评估,炎症细胞因子水平(白细胞介素-6 (IL-6)、白细胞介素-8 (IL-8))和脂质概况(用脂质染色法测量)用酶联免疫吸附测定法评估。未经处理的细胞作为对照进行比较。 与未经处理的细胞相比,补充欧米伽-3 脂肪酸可使细胞活力呈剂量依赖性增加。在最佳浓度下,EPA 和 DHA 可分别显著提高细胞活力 30% 和 35% (P < 0.05)。此外,补充欧米伽-3 脂肪酸可显著降低炎症细胞因子水平,与未处理细胞相比,IL-6 和 IL-8 的分泌量减少了 50%(P < 0.01)。此外,脂质染色显示,补充欧米伽-3 脂肪酸后,角膜上皮细胞的脂质分布和组织得到改善,表明泪膜的稳定性增强。 体外研究结果表明,补充欧米伽-3脂肪酸对与DES相关的细胞标记物产生有益影响。

ABSTRACT Research indicates heavy backpacks can cause students to adjust their posture, potentially harming their spine and shoulders. This study focuses on musculoskeletal pain in schoolchildren in Bangalore, attributed to backpack weight, and examines postural impacts in both urban and rural settings. With consent, 500 students from various schools underwent physical measurements, including backpack weight, and provided data through questionnaires. Postural angles were assessed without backpacks to determine the impact of weight. On average, students carried backpacks weighing 6.53 kg, about 13.53% of their body weight. Pain was reported by 50.9% of boys and 63.9% of girls, with a higher incidence among girls from private schools (88.2%) compared to boys from government schools (51.6%). A significant link was found between heavier backpacks and decreased craniovertebral angle, head on neck (HON), and head and neck on trunk (HNOT) angles, aligning with increased pain prevalence. This underscores the health risks of heavy school backpacks and the need for weight management.
摘要 研究表明,沉重的书包会导致学生调整姿势,从而对脊柱和肩膀造成潜在伤害。本研究的重点是班加罗尔学童因书包重量而导致的肌肉骨骼疼痛,并考察了城市和农村环境对姿势的影响。 在征得同意后,来自不同学校的 500 名学生接受了包括书包重量在内的身体测量,并通过问卷调查提供了数据。在不背书包的情况下对姿势角度进行了评估,以确定重量的影响。 学生背包的平均重量为 6.53 千克,约占体重的 13.53%。50.9%的男生和 63.9%的女生报告了疼痛,其中私立学校女生的疼痛发生率(88.2%)高于公立学校男生(51.6%)。 研究发现,较重的书包与颅椎角度、头颈角度(HON)和头颈与躯干角度(HNOT)的减小有明显联系,这与疼痛发生率的增加一致。这强调了沉重书包对健康的危害以及控制体重的必要性。

ABSTRACT Healthcare-associated infections (HAIs), also known as nosocomial infections, are a significant risk in hospitals, leading to increased morbidity and mortality among patients due to poor hygiene practices. This descriptive study involved 350 participants from Wuhan’s private hospitals. Respondents answered a questionnaire distributed in person or via email, and data were analyzed using SPSS version 25.0. Analysis revealed a knowledge gap among healthcare workers in infection control, affecting their ability to maintain hospital cleanliness. Education levels were assessed, showing that 60% of participants held diplomas or higher qualifications. The study highlights the urgent need for enhanced training and information dissemination on infection control practices among healthcare staff. Identifying this knowledge and practice gap is crucial for improving hospital hygiene and reducing HAI incidence.

ABSTRACT Gutta-percha is commonly used in endodontic therapy for obturating root canals after cleaning and shaping procedures. Warm and cold gutta-percha techniques are two common methods employed for obturation, each with its own advantages and limitations. Twenty extracted human teeth with single-rooted canals were selected and divided into two groups: warm gutta-percha obturation and cold gutta-percha obturation. In the warm gutta-percha group, gutta-percha was heated to a predetermined temperature using a warm gutta-percha heating device and injected into the root canal using a heated carrier. In the cold gutta-percha group, gutta-percha was applied directly to the root canal without prior heating. Root canal obturation quality was assessed using radiographic imaging to evaluate the presence of voids, completeness of obturation, and adaptation to the canal walls. Micro-computed tomography (micro-CT) analysis was also performed to quantify the volume of obturating material and assess the three-dimensional distribution of gutta-percha within the root canal space. Both warm and cold gutta-percha techniques demonstrated effective obturation of root canals, with comparable outcomes in terms of void formation, completeness of obturation, and adaptation to canal walls. However, micro-CT analysis revealed differences in the volume and distribution of gutta-percha within the root canal space. Warm gutta-percha obturation exhibited more uniform distribution of gutta-percha material and higher volumetric filling compared to cold gutta-percha obturation. Additionally, the warm gutta-percha technique demonstrated superior flowability and adaptation to irregularities within the root canal system. In this in vitro study, warm gutta-percha obturation demonstrated advantages over cold gutta-percha obturation in terms of volumetric filling, distribution within the root canal space, and adaptation to canal irregularities.
摘要 在牙髓治疗中,在完成清洁和塑形程序后,通常会使用古塔漆来封固根管。温敷和冷敷是两种常用的灌封方法,各有其优点和局限性。 我们选择了 20 颗带有单根根管的拔牙,并将其分为两组:温热古塔漆封堵法和冷古塔漆封堵法。在温热古塔波卡组,使用温热古塔波卡加热装置将古塔波卡加热到预定温度,然后使用加热载体将古塔波卡注入根管。在冷古塔波胶组中,古塔波胶无需事先加热,直接注入根管。根管封闭质量通过放射成像进行评估,以评价是否存在空隙、封闭是否完整以及与根管壁的适应性。此外,还进行了显微计算机断层扫描(micro-CT)分析,以量化封堵材料的体积,并评估根管内古塔漆的三维分布情况。 温性和冷性古塔漆技术都能有效地封堵根管,在空隙形成、封堵的完整性和对根管壁的适应性方面效果相当。然而,显微 CT 分析表明,根管内的水门汀数量和分布存在差异。与冷古塔水门汀相比,温古塔水门汀封药的古塔水门汀材料分布更均匀,填充体积更大。此外,温热的古塔漆技术还表现出了更好的流动性和对根管系统内不规则情况的适应性。 在这项体外研究中,温热古塔漆封堵术在体积填充、根管空间内的分布以及对根管不规则的适应性方面都比冷古塔漆封堵术更有优势。

ABSTRACT Pterygium is a common ocular surface disorder characterized by the growth of fibrovascular tissue onto the cornea, leading to discomfort and visual impairment. Various surgical techniques, including conjunctival autografting, amniotic membrane transplantation, and bare sclera excision, are employed in the management of pterygium. Cultured human conjunctival epithelial cells were subjected to simulated pterygium conditions, mimicking the fibrovascular proliferation observed in vivo. Subsequently, different surgical techniques, including conjunctival autografting, amniotic membrane transplantation, and bare sclera excision, were simulated in vitro. Cell viability, proliferation, migration, and inflammatory cytokine expression were assessed using various assays, including MTT assay, scratch assay, and enzyme-linked immunosorbent assay (ELISA). Untreated cells served as controls for comparison. Conjunctival autografting demonstrated superior outcomes in terms of cell viability and proliferation compared to amniotic membrane transplantation and bare sclera excision. Autografted cells exhibited a significantly higher percentage of viable cells and enhanced proliferative capacity compared to cells subjected to other surgical techniques (P < 0.05). Additionally, conjunctival autografting promoted faster cell migration into the defect area, resulting in more rapid wound closure compared to other techniques. Furthermore, reduced expression of inflammatory cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), was observed in cells treated with conjunctival autografts compared to other groups. In vitro findings suggest that conjunctival autografting may offer superior outcomes in the management of pterygium compared to amniotic membrane transplantation and bare sclera excision.
摘要 翼状胬肉是一种常见的眼表疾病,其特征是纤维血管组织长在角膜上,导致不适和视力障碍。翼状胬肉的治疗采用了多种手术方法,包括结膜自体移植、羊膜移植和裸巩膜切除术。 对培养的人类结膜上皮细胞进行了翼状胬肉模拟试验,模拟体内观察到的纤维血管增生。随后,在体外模拟了不同的手术方法,包括结膜自体移植、羊膜移植和裸巩膜切除术。通过 MTT 试验、划痕试验和酶联免疫吸附试验(ELISA)等多种试验方法对细胞的活力、增殖、迁移和炎性细胞因子的表达进行了评估。未经处理的细胞作为对照进行比较。 与羊膜移植和裸巩膜切除术相比,结膜自体移植在细胞存活率和增殖方面表现出更优越的结果。与采用其他手术技术的细胞相比,自体移植细胞的存活率明显更高,增殖能力也更强(P < 0.05)。此外,结膜自体移植还能促进细胞更快地迁移到缺损区域,从而使伤口比其他技术更快地愈合。此外,与其他组别相比,用结膜自体移植物处理的细胞中白细胞介素-6(IL-6)和肿瘤坏死因子-α(TNF-α)等炎症细胞因子的表达量有所减少。 体外研究结果表明,与羊膜移植和裸巩膜切除术相比,结膜自体移植在翼状胬肉的治疗中可能具有更好的疗效。

ABSTRACT Tele-orthodontics, the application of telecommunications technology in orthodontic care, has emerged as a promising tool to enhance patient compliance and facilitate treatment monitoring. In traditional orthodontic practice, patient compliance and monitoring are pivotal but often challenging aspects. Tele-orthodontics offers a solution by providing remote communication and monitoring capabilities, potentially improving patient engagement and treatment outcomes. This study conducted a retrospective analysis of orthodontic patients who utilized tele-orthodontics as part of their treatment plan. A total of 100 patients were included in the study, with ages ranging from 12 to 40 years old. Patients were provided with mobile applications or web-based platforms enabling them to communicate with their orthodontists, submit progress images, and receive feedback remotely. Treatment compliance was assessed based on adherence to scheduled appointments, wearing of orthodontic appliances, and completion of prescribed exercises. The analysis revealed a significant improvement in patient compliance with the implementation of tele-orthodontics. Adherence to scheduled appointments increased by 30%, with patients attending 95% of their appointments compared to 65% before the introduction of tele-orthodontics. Moreover, compliance with wearing orthodontic appliances showed a remarkable rise, with patients consistently wearing their appliances for an average of 22 h per day, up from 14 h per day previously. Additionally, the completion rate of prescribed exercises saw a notable enhancement, with 80% of patients completing their exercises as instructed, compared to 50% previously. Tele-orthodontics plays a significant role in enhancing patient compliance and treatment monitoring in orthodontic care. The remote communication and monitoring capabilities provided by tele-orthodontic platforms empower patients to actively participate in their treatment process, leading to improved adherence to appointments, better compliance with wearing orthodontic appliances, and increased completion of prescribed exercises. These findings underscore the importance of integrating tele-orthodontics into orthodontic practice to optimize patient outcomes and satisfaction.
摘要 远程正畸是将电信技术应用于正畸治疗的一种新兴技术,是提高患者依从性和促进治疗监测的一种有前途的工具。在传统的正畸实践中,患者的依从性和监测是至关重要的,但往往具有挑战性。远程正畸通过提供远程通信和监控功能提供了一种解决方案,有可能提高患者的参与度和治疗效果。 本研究对使用远程正畸作为治疗计划一部分的正畸患者进行了回顾性分析。共有 100 名患者参与了这项研究,他们的年龄从 12 岁到 40 岁不等。患者可通过移动应用程序或网络平台与正畸医生进行交流、提交进度图像并远程接收反馈。治疗依从性的评估依据是患者是否按时赴约、是否佩戴正畸装置以及是否完成规定的练习。 分析结果表明,实施远程正畸后,患者的依从性有了显著提高。按期就诊率提高了 30%,患者的就诊率达到 95%,而在采用远程正畸技术之前,这一比例仅为 65%。此外,患者佩戴正畸矫治器的依从性也有显著提高,患者平均每天佩戴正畸矫治器的时间从之前的 14 小时增加到 22 小时。此外,规定练习的完成率也有显著提高,80% 的患者按照指示完成了练习,而以前只有 50%。 远程正畸在提高正畸护理中患者的依从性和治疗监测方面发挥了重要作用。远程正畸平台提供的远程通信和监控功能使患者有能力积极参与治疗过程,从而提高了预约的依从性、佩戴正畸装置的依从性以及规定练习的完成率。这些发现强调了将远程正畸整合到正畸实践中以优化患者治疗效果和满意度的重要性。

ABSTRACT The selection between Zirconia crowns and metal crowns for anterior teeth restorations is pivotal in prosthodontics due to their distinct properties. However, a comprehensive investigation into their effectiveness in anterior tooth restorations is warranted. This in vitro study aimed to compare the effectiveness of Zirconia crowns and metal crowns in anterior teeth restorations. A total of thirty extracted human maxillary central incisors were prepared to receive crowns and randomly allocated into two groups: group A, zirconia crowns; and group B, metal crowns. The crowns were fabricated following standardized protocols and cemented onto the prepared teeth. Various tests, including fracture resistance, marginal adaptation, and color-matching assessment, were conducted on the samples. The mean fracture resistance of Zirconia crowns (Group A) was determined to be 320 N (SD ± 25), whereas it was 280 N (SD ± 30) for metal crowns (Group B). Marginal adaptation assessment revealed a mean gap width of 50 microns (SD ± 10) for Zirconia crowns and 70 microns (SD ± 15) for metal crowns. Evaluation of color matching showed a higher percentage of acceptable matches for Zirconia crowns compared to metal crowns. Zirconia crowns exhibited superior fracture resistance, marginal adaptation, and color matching in comparison to metal crowns for anterior teeth restorations. These findings advocate for Zirconia crowns as a more effective choice for restoring anterior teeth, offering both strength and esthetic appeal.
摘要 由于氧化锆冠和金属冠具有不同的特性,因此在前牙修复中对它们的选择至关重要。然而,有必要对它们在前牙修复中的有效性进行全面研究。 这项体外研究旨在比较氧化锆冠和金属冠在前牙修复中的效果。研究人员准备了三十颗拔出的人类上颌中切牙,并将其随机分为两组:A 组,氧化锆冠;B 组,金属冠。牙冠按照标准化方案制作,并粘接在准备好的牙齿上。对样品进行了各种测试,包括抗折性、边缘适应性和配色评估。 经测定,氧化锆牙冠(A 组)的平均抗折力为 320 牛顿(标准偏差 ± 25),而金属牙冠(B 组)的抗折力为 280 牛顿(标准偏差 ± 30)。边缘适应性评估显示,氧化锆冠的平均间隙宽度为 50 微米(标准差 ± 10),金属冠为 70 微米(标准差 ± 15)。颜色匹配评估显示,与金属冠相比,氧化锆冠的可接受匹配比例更高。 在前牙修复方面,与金属冠相比,氧化锆冠在抗折性、边缘适应性和颜色匹配方面都更胜一筹。这些研究结果表明,氧化锆冠是修复前牙的更有效选择,它既有强度又有美观性。

ABSTRACT Pediatric dental anxiety poses a significant challenge in the delivery of dental care, often resulting in compromised treatment outcomes and negative experiences for both patients and dental professionals. A randomized controlled trial (RCT) was conducted involving 120 pediatric dental patients aged 4 to 10 years old, presenting with varying degrees of dental anxiety. Patients were randomly assigned to three groups: Group A received tell-show-do (TSD) technique, Group B received audiovisual distraction (AVD), and Group C received non-pharmacological behavior guidance (NPBG). Anxiety levels were assessed using a standardized anxiety scale before and after the dental procedure. Patient cooperation during treatment, as well as dentist and parent satisfaction, was also evaluated. The study revealed significant reductions in anxiety levels across all groups post-treatment. However, Group B (AVD) demonstrated the most substantial reduction in anxiety scores, with a mean decrease of 60% from baseline. Group A (TSD) and Group C (NPBG) showed comparable reductions in anxiety levels, with mean decreases of 45% and 50%, respectively. Patient cooperation during treatment was highest in Group B, followed by Groups C and A. Dentist and parent satisfaction scores were significantly higher in Group B compared to the other groups. AVD emerged as the most effective behavioral management technique for treating anxious pediatric dental patients, resulting in significant reductions in anxiety levels and higher levels of patient cooperation during treatment compared to TSD and NPBG techniques.
摘要 儿童牙科焦虑症是牙科治疗过程中的一个重大挑战,往往会影响治疗效果,给患者和牙科专业人员带来负面体验。 一项随机对照试验(RCT)涉及 120 名年龄在 4 到 10 岁之间、有不同程度牙科焦虑的儿童牙科患者。患者被随机分配到三组:A 组接受告诉-展示-做(TSD)技术,B 组接受视听分散(AVD),C 组接受非药物行为指导(NPBG)。在牙科治疗前后使用标准化焦虑量表评估焦虑水平。此外,还对患者在治疗过程中的合作情况以及牙医和家长的满意度进行了评估。 研究显示,所有组别在治疗后的焦虑水平都有明显下降。不过,B 组(AVD)的焦虑评分下降幅度最大,与基线相比平均下降了 60%。A组(TSD)和C组(NPBG)的焦虑水平下降幅度相当,平均降幅分别为45%和50%。B 组患者在治疗过程中的配合度最高,其次是 C 组和 A 组。与其他组相比,B 组的牙医和家长满意度得分明显更高。 与 TSD 和 NPBG 技术相比,AVD 是治疗儿童牙科焦虑症患者最有效的行为管理技术,能显著降低焦虑水平,提高患者在治疗过程中的配合度。

ABSTRACT Endodontic procedures require precise manipulation and visualization to achieve optimal treatment outcomes. Magnification and enhanced visualization tools, such as dental loupes and dental operating microscopes (DOMs), have been introduced to enhance precision in endodontic practice. Extracted human teeth with single-rooted canals were divided into two groups: a control group without magnification and an experimental group with magnification and enhanced visualization. Endodontic procedures, including access cavity preparation, cleaning, shaping, and obturation, were performed on both groups. The experimental group utilized either dental loupes or a DOM for enhanced visualization. Treatment outcomes were assessed based on predefined criteria, including the quality of access cavity preparation, canal cleanliness, shaping, and obturation. Scores were assigned to each criterion to quantify treatment precision. The use of magnification and enhanced visualization significantly improved precision in endodontic procedures compared to the control group. Access cavity preparation in the experimental group resulted in more conservative tooth structure removal and improved visualization of canal orifices. Canal cleanliness, shaping, and obturation were markedly superior in the experimental group, with higher scores indicating better precision. The experimental group also exhibited a reduced incidence of procedural errors and complications compared to the control group. Magnification and enhanced visualization tools, such as dental loupes and DOMs, enhance precision in endodontic procedures.
摘要 根管治疗过程需要精确的操作和可视化,以达到最佳治疗效果。放大和增强可视化工具,如牙科放大镜和牙科手术显微镜(DOMs),已被引入牙髓治疗实践中以提高精确度。 拔出的带有单根牙管的人类牙齿被分为两组:未使用放大镜的对照组和使用放大镜和增强可视化的实验组。两组均进行了牙髓治疗程序,包括通路洞准备、清洁、整形和封闭。实验组使用牙科放大镜或 DOM 增强可视性。治疗结果根据预先确定的标准进行评估,包括通路洞准备质量、根管清洁度、成形和封闭。对每项标准进行评分,以量化治疗精度。 与对照组相比,使用放大镜和增强可视化显著提高了根管治疗的精确度。实验组的牙洞预备使得牙齿结构的去除更加保守,并改善了牙髓管孔的可视性。实验组的根管清洁度、塑形和封闭效果明显优于对照组,得分越高说明精确度越高。与对照组相比,实验组的程序错误和并发症发生率也有所降低。 放大镜和增强型可视化工具(如牙科放大镜和 DOM)可提高根管治疗过程的精确度。
