The modern, dynamic world can’t imagine its development without carrying the concept of advancement in composite materials. Various researches are going on in this field to achieve the desired standard. Natural fiber reinforced polymer composite (NFPC) has a huge affinity to interchange the composite made up of synthetic fiber. This is primarily because of the advantages like light-weight, non-toxic, nonabrasive, easy availability, low cost and biodegradable properties. The specific mechanical properties like specific tensile modulus and other specific properties of natural fiber gives a satisfying result for composites as compared to synthetic fiber based composites. The general objective of this work was to develop a composite from bamboo fibers and HDPE reinforced with red bauxite mud residues to ensure good thermal stability and improve the physico-mechanical properties in traction and flexion. The morphology of the composites showed that there was a homogenous dispersion of BF at lower weight fraction, although fibre agglomeration was noticed at higher weight fraction. The results of this study revealed that treated bamboo fibres are suitable for reinforcing HDPE. It appears from these studies that the formulations produced are in accordance with the ASTM standard and can validly be used for the thermal comfort of buildings to improve the comfort of the population in sustainable habitats.
现代世界充满活力,其发展离不开复合材料的进步。为了达到理想的标准,这一领域正在进行各种研究。天然纤维增强聚合物复合材料(NFPC)与合成纤维复合材料相比具有巨大的亲和力。这主要是因为天然纤维具有重量轻、无毒、无磨损、易于获得、成本低和可生物降解等优点。与基于合成纤维的复合材料相比,天然纤维的特定机械性能(如特定拉伸模量和其他特定性能)能为复合材料带来令人满意的结果。这项工作的总体目标是开发一种由竹纤维和高密度聚乙烯(HDPE)以及红矾泥残渣增强的复合材料,以确保良好的热稳定性,并改善牵引和弯曲时的物理机械性能。复合材料的形态显示,在较低的重量分数下,BF 呈均匀分散状态,但在较高的重量分数下,BF 出现聚结。研究结果表明,经过处理的竹浆适用于增强高密度聚乙烯。从这些研究中可以看出,所生产的配方符合 ASTM 标准,可以有效地用于建筑物的热舒适性,以改善可持续居住环境中人们的舒适度。

Biomarkers for assessing disease progression and treatment outcomes of oral submucous fibrosis (OSMF) have gained significant attention in recent years. This review provides an overview of the current research on biomarkers in OSMF and their potential implications in clinical practice. The review focuses on the different categories of biomarkers that have shown promise in assessing disease progression and treatment outcomes in OSMF. Epithelial dysplasia markers, including Ki-67, p53, and cyclin D1, are discussed in relation to dysplastic changes observed in OSMF. Inflammatory and immune markers, such as cytokines, chemokines, and inflammatory mediators, are explored for their role in OSMF progression. The dysregulation of extracellular matrix remodelling is highlighted, with a discussion on matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) as potential biomarkers. Furthermore, the review delves into biomarkers for treatment response and outcome prediction. Collagen turnover markers, including pro-collagen type I and MMPs, are examined as indicators of collagen synthesis and degradation. Oxidative stress markers, such as malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx), are evaluated for their ability to reflect oxidative stress and antioxidant status. The review also touches upon the potential of epigenetic markers, such as DNA methylation and histone modifications, in predicting treatment response and prognosis in OSMF. Additionally, the review explores the use of imaging techniques, including optical coherence tomography (OCT), autofluorescence imaging, and confocal microscopy, for assessing structural changes and biomarker expression in OSMF. It discusses the potential of molecular imaging modalities, such as positron emission tomography (PET) and molecular MRI, for visualizing specific biomarkers in OSMF. Moreover, the review highlights the importance of genomics approaches, including genomics, transcriptomics, proteomics, and metabolomics, in identifying novel biomarkers and unraveling molecular pathways in OSMF. We emphasize the potential of biomarkers in improving patient care and management in OSMF. It acknowledges the challenges in biomarker validation, standardization, and cost-effectiveness for widespread clinical use. The review calls for further research in emerging areas, such as non-coding RNAs, microRNA panels, and multi-modal biomarker approaches, to enhance our understanding of OSMF and facilitate personalized treatment strategies.    
近年来,用于评估口腔黏膜下纤维化(OSMF)疾病进展和治疗结果的生物标志物获得了极大的关注。本文综述了OSMF生物标志物的研究现状及其在临床实践中的潜在意义。这篇综述的重点是不同类别的生物标志物,它们在评估OSMF的疾病进展和治疗结果方面显示出希望。上皮发育不良标志物,包括Ki-67、p53和cyclin D1,与OSMF中观察到的发育不良变化有关。炎症和免疫标志物,如细胞因子、趋化因子和炎症介质,在OSMF进展中的作用被探索。强调了细胞外基质重塑的失调,并讨论了基质金属蛋白酶(MMPs)和金属蛋白酶组织抑制剂(TIMPs)作为潜在的生物标志物。此外,本文还深入探讨了治疗反应和预后预测的生物标志物。胶原转换标志物,包括前胶原I型和MMPs,作为胶原合成和降解的指标。氧化应激标志物,如丙二醛(MDA)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPx),评估其反映氧化应激和抗氧化状态的能力。该综述还涉及表观遗传标记,如DNA甲基化和组蛋白修饰,在预测OSMF治疗反应和预后方面的潜力。此外,本文还探讨了成像技术的使用,包括光学相干断层扫描(OCT)、自体荧光成像和共聚焦显微镜,用于评估OSMF的结构变化和生物标志物表达。它讨论了分子成像方式的潜力,如正电子发射断层扫描(PET)和分子MRI,用于可视化OSMF中的特定生物标志物。此外,综述强调了基因组学方法的重要性,包括基因组学,转录组学,蛋白质组学和代谢组学,在识别新的生物标志物和揭示OSMF的分子途径方面。我们强调生物标志物在改善OSMF患者护理和管理方面的潜力。它承认在生物标志物验证、标准化和广泛临床使用的成本效益方面的挑战。这篇综述呼吁在新兴领域进行进一步的研究,如非编码rna、microRNA面板和多模态生物标志物方法,以增强我们对OSMF的理解,并促进个性化治疗策略。

Introduction: Rugoscopy is the examination of palatal rugae patterns, whereas cheiloscopy is the forensic investigation technique for examining lip impressions. The palatine rugae and lip impressions are distinguishing anatomical characteristics that are specific to every person and can be utilised effectively for human identification. Aim: The purpose of this investigation is to establish a relationship between rugoscopic and cheiloscopic patterns in minors. Materials and methods: A descriptive involving 100 subjects aged 5 to 15 years was conducted. Rugae patterns and lip impressions were analysed and recorded. The Lysell classification (1955) and the Thomas and Kotze classification (1983) evaluate rugoscopic patterns based on their length and their shape and cohesion, respectively. Suzuki and Tsuchihashi classification was used to assess cheiloscopic patterns. The research was conducted for one month, and SPSS version 23.0 was used for analysis. Results: In both sexes, the predominant palatal rugae patterns were undulating, followed by curved, and then straight. Males had Type V dominant, followed by Type IV, while females had Type I' dominant, followed by Type I. Conclusion: Cheiloscopy is a more reliable tool than rugoscopy for human identification in the field of forensic science, as shown by our study's conclusion that rugoscopy yielded similar results but cheiloscopy yielded distinct results.

Introduction:  The objective of this study was to investigate the awareness and attitude of geriatric patients regarding implant prosthodontic options. Methods: A cross-sectional survey was conducted among 200 geriatric patients aged 65 years and above who presented to the prosthodontic department of a tertiary care dental hospital. Data were collected using a structured questionnaire that assessed demographic information, awareness of implant prosthodontic options, and attitude towards these treatment options. Descriptive statistics and inferential statistics were used for data analysis. Results: Of the 200 participants, 60.0% were aware of implant prosthodontic options. The most common sources of information were dentists (66.7%), followed by friends or family members (33.3%) and the internet (25%). Cost was reported as a significant barrier to seeking implant prosthodontic treatment (30%). Among participants aware of implant prosthodontic options, 70.0 % had a positive attitude towards this treatment modality.. Concerns included pain during or after treatment , implant failure, and infection . Conclusion: The findings suggest that a little more than half of the geriatric patients in this study were aware of implant prosthodontic options, with a majority having a positive attitude towards this treatment modality. Dental professionals play a vital role in promoting awareness, while addressing patient concerns and providing comprehensive education can improve acceptance and satisfaction among geriatric patients considering implant prosthodontic options.

Background: A prosthodontic rehabilitation's success depends critically on striking a balance between new and traditional treatment modalities. These prosthodontic treatment options include partial dentures with attachments. The majority of conventional RPD are adequately designed, but they are rarely utilised by patients because they don't like how they look or how well they retain information. This article describes a modified extended precision attachment for removing metal display to improve the aesthetics and preservation of a long-span partial edentulous arch restored using prosthodontic rehabilitation. A 68-year-old male patient was referred to the prosthodontics department for the purpose of replacing lost teeth. Kennedy's class I mode 1 in the mandibular arch with a worn out dentition were identified during clinical testing. Maxillary and mandibular arches were precisely planned for fixed and removable partial denture. The underlying residual alveolar ridge and the retentive components are both necessary for the RPD to be successful. In this case study, the use of precision attachments results in a more aesthetically pleasing end and enhanced retention on the mandibular partial dentures. Clinical significance: By applying precision attachment, the treatment plan adequately described restores the appearance, masticatory function, and enhances the prosthesis' retention. Keywords: Fixed partial denture, Flexible denture, Precision attachment,cast partial denture.
背景:修复康复的成功关键取决于在新的和传统的治疗方式之间取得平衡。这些修复治疗方案包括带附着物的部分假牙。大多数传统的RPD都设计得很好,但很少被患者使用,因为他们不喜欢它们的外观或它们保留信息的能力。本文介绍了一种改进的扩展精密附件,用于去除金属显示器,以改善修复修复的大跨度部分无牙弓的美观性和保存性。一名68岁男性病人被转介到修复科,目的是替换掉的牙齿。在临床测试中发现下颌弓的肯尼迪I类1型牙列磨损。上颌和下颌弓精确规划固定和活动局部义齿。潜在的残余牙槽嵴和保留部件都是RPD成功的必要条件。在本案例研究中,使用精密附着体可以获得更美观的端部,并增强下颌部分义齿的固位。临床意义:通过精确附着体的应用,充分描述了修复方案,修复了义肢的外观和咀嚼功能,增强了义肢的固位。关键词:固定义齿,柔性义齿,精密附着体,铸造义齿

A COMPARATIVE EVALUATION OF ENAMEL SURFACE ROUGHNESS OF TWO DIFFERENT BONDING ADHESIVES AFTER DEBONDING WITH ATOMIC FORCE MICROSCOPY 原子力显微镜对两种不同黏合剂脱粘后牙釉质表面粗糙度的比较评价
Pub Date : 2023-04-25 DOI: 10.58935/joas.v2i1.22

Introduction: The goal of this research was to evaluate the pain felt by patients after veneers were debonded and gum remnants were removed using a tungsten carbide (TC) brush from two different cement frameworks: light fix composite and glass ionomer concrete glues. So long as we assume the null hypothesis is true, the two adhesive solutions do not vary in their ability to smooth out imperfections on the enamel surface. Materials and methods :- Based on the consideration and prohibition models, this in vitro study examined sixty newly removed human premolar teeth (n = 60) to assess orthodontic plans. Light fix cement (Trans bond XT, 3M Unitek, Monrovia, CA) was used to strengthen the metal portions in Group I (n = 30), whereas light glass ionomer concrete (GC Fuji Ortho LC, Tokyo, Japan) was used to accomplish the same in Group II (n = 30). The dried residues of the concrete glue were removed using a TC brush and a slow-speed handpiece. Maximum roughness (Rmax), root mean square roughness (Rq), and roughness (Ra) were all determined at time zero (before holding). and their attributes were compared to those at time two (after debonding and completion). Results:-The two groups had very different experiences with the roughness of the polished surface when held. The composite resin and glass ionomer cement groups had statistically significant (p0.001) differences in surface roughness.  Conclusion:- After debonding the sections and finishing with a TC brush, the surface roughness of the veneer significantly increased with both the light fix and the glass ionomer strong concrete structures. The enamel surface roughness of the light cure group was worse than that of the glass ionomer cement group.
本研究的目的是评估患者在使用碳化钨(TC)刷从两种不同的水泥框架(光固定复合材料和玻璃离子混凝土胶)中去除贴面和牙龈残留物后所感受到的疼痛。只要我们假设零假设是正确的,这两种粘合剂溶液在平滑牙釉质表面缺陷的能力上并没有变化。材料和方法:-基于考虑和禁止模型,本体外研究检查了60颗新拔除的人类前磨牙(n = 60),以评估正畸计划。轻固定水泥(Trans bond XT, 3M Unitek, Monrovia, CA)用于加强第一组的金属部分(n = 30),而轻玻璃离子混凝土(GC Fuji Ortho LC,东京,日本)用于完成相同的第二组(n = 30)。使用TC刷和慢速机头去除干燥的混凝土胶残留物。最大粗糙度(Rmax),均方根粗糙度(Rq)和粗糙度(Ra)都在时间0(保持之前)确定。并将它们的属性与时间2(在脱键和完成后)的属性进行比较。结果:-两组在持有抛光表面的粗糙度方面有非常不同的体验。复合树脂组和玻璃离聚体水泥组在表面粗糙度上有统计学意义(p0.001)差异。结论:-在用TC刷去粘接切片和整理后,贴面的表面粗糙度显着增加,无论是光固定还是玻璃离子强混凝土结构。光固化组牙釉质表面粗糙度较玻璃离子水门合剂组差。
