Introduction: Plaster is widely used in dentistry for the production of master casts, as a binder in investment materials and as an auxiliary material in the laboratory stages of denture production. Due to its brittleness, there is a constant need to improve its mechanical properties. In this regard, in the research we started from the assumption that increasing the proportion of powder during the preparation of plaster improves its mechanical properties. The aim of this research wasto determine the significance of the change in the ratio of powder and liquid to the mechanical characteristics of plaster (compressive strength). Material and methods: Three types of plaster were used in the research: type 2, 3 and 4. For each type of plaster, three samples were made with different ratio of powder and amount of water (n = 9). After 24 hours, the samples were analyzed at the Faculty of Mechanical Engineering in Niš, on a universal testing machine. Results: Plaster type 2 showed the lowest values of compressive strength, and higher values of types 3 and 4, regardless of the ratio of plaster powder and water. As the powder content increased, the compressive strength of the samples increased. Conclusion: In order to improve the compressive strength, the proportion of powder in the liquid phase can be increased during the preparation of the material without visible changes in its structure.
石膏在牙科中广泛用于制作母模,在投资材料中作为粘结剂,在义齿生产的实验室阶段作为辅助材料。由于其脆性,需要不断提高其力学性能。为此,我们在研究中假设在石膏制备过程中增加粉末的比例可以改善石膏的力学性能。本研究的目的是确定粉液比变化对石膏力学特性(抗压强度)的意义。材料与方法:采用2、3、4型三种石膏。对于每种石膏,用不同比例的粉末和水量制作3个样品(n = 9)。24小时后,样品在尼什机械工程学院的通用试验机上进行分析。结果:无论石膏粉与水的比例如何,2型石膏的抗压强度最低,3型和4型石膏的抗压强度较高。随着粉末含量的增加,试样的抗压强度增大。结论:为了提高材料的抗压强度,在制备过程中可以在不改变材料结构的前提下增加液相中粉末的比例。

The basis of the problem: Parry Romberg syndrome (PRS) is a rare developmental disorder manifesting as a slow and progressive atrophy of the face which is often unilateral, hence also termed as rpogressivehemifacial atrophy. The extent of the atrophy may vary, involving the superficial skin extending upto the underlying bone. The clinical features of PRS include craniofacial, neurologic, ophthalmic and dermatological manifestations, which result in various functional and psychological problems. PRS and linear scleroderma belong to the same disease spectrum. There can be demarcating line between the normal and abnormal skin seen in PRS, termed as "en coup de sabre". PRS is most commonly seen in females and involves the left side of the face. Method: We hereby report a case of PRS in a young girl presenting with en coup de sabre appearance on the right side of face. Results: Microsurgical facial reconstruction of the affected side is known to be the gold standard method for correction of the facial symmetry. In our case, the patient is currently kept under long term follow up and cosmetic surgical treatment will be planned once the atrophy attains stability. Conclusion: The association of PRS with linear scleroderma may present difficulty in its diagnosis. Hence, careful recording of the history and clinical examination with appropriate investigations can aid in establishing the correct diagnosis.
问题的基础:Parry Romberg综合征(PRS)是一种罕见的发育障碍,表现为面部缓慢和进行性萎缩,通常是单侧的,因此也被称为进行性面部萎缩。萎缩的程度可能不同,包括浅层皮肤延伸到下面的骨头。PRS的临床特征包括颅面、神经、眼和皮肤表现,并导致各种功能和心理问题。PRS与线性硬皮病属于同一疾病谱系。在PRS中可以看到正常和异常皮肤之间的分界线,称为“en coup de sabre”。PRS最常见于女性,涉及左脸。方法:我们在此报告一例年轻女孩的PRS,表现为右侧面部的剑变外观。结果:患侧面部显微外科重建被认为是矫正面部对称性的金标准方法。在我们的病例中,患者目前正在进行长期随访,一旦萎缩达到稳定,将计划进行整形手术治疗。结论:PRS与线性硬皮病的相关性可能存在诊断困难。因此,仔细记录病史和适当的临床检查有助于建立正确的诊断。

Introduction: Under the concept of regenerative periodontal therapy, there are two approaches: the first is the passive regeneration conceptthat includes bone substituents and guided periodontal regeneration by using of biomembranes and the second concept of active regeneration that impliesthe use of growth factors. The aim of the passive regeneration, by using of bone matrix (bone substituens) has been stabilization and bone defects management, preventing epithelial tissue growth, as well as saving space for the new tissue regeneration. This concept implies the use of autogenous transplantats, xenografts, allografts, as well as alloplastic materials. The carriers for active tissue regeneration, growth factors -GF are biological mediators that regulate cellular processes and that is crucial for the tissue regeneration. Aim:Presentation ofmodern approaches to periodontal therapy thatare focused on the attachment regeneration and complete reconstruction of periodontal tissue. Conclusion: In the future, periodontal regenerative therapy with periodontalligament progenitor cells should encourage repopulation of the areas that have been affected by periodontal disease.
在再生牙周治疗的概念下,有两种方法:第一种是被动再生概念,包括骨替代物和利用生物膜引导牙周再生;第二种是主动再生概念,意味着使用生长因子。利用骨基质(骨替代物)进行被动再生的目的是稳定和控制骨缺损,防止上皮组织的生长,并为新组织再生节省空间。这一概念意味着自体移植、异种移植、同种异体移植以及同种异体材料的使用。生长因子是活性组织再生的载体,是调节细胞过程的生物介质,对组织再生至关重要。目的:介绍以牙周组织附着体再生和完全重建为重点的现代牙周治疗方法。结论:在未来,用牙周炎祖细胞进行牙周再生治疗应能促进牙周病影响区域的再生。

Introduction: Micronutrients play a potent role in the functioning of the different systems of the organism. It is necessary to sustain an adequate status of the micronutrients for maintaining the optimal condition of the oral cavity. The aim: Toemphasize the importance of different micronutrients for the normal functioning of the oral cavity, as well as their influence on the occurrence of various diseases of the soft and hard tissues of the oral cavity. Conclusion: Micronutrients such as vitamin C, B9 and E, calcium, zinc, copper and iron have a role in development so as anti-inflammatory and antioxidants properties Deficiency of certain micronutrients plays an important role in the development of periodontitis and caries. People with chronic inflammatory bowel disease, as well as children, pregnant and breastfeeding women, are usually deficient in these vitamins and therefore often susceptible to the development of inflammatory changes in soft tissues of oral cavity , periodontitis and caries.
微量营养素在机体不同系统的功能中起着重要作用。为了维持口腔的最佳状态,维持足够的微量营养素是必要的。目的:强调不同微量元素对口腔正常功能的重要性,以及它们对口腔软硬组织各种疾病发生的影响。结论:维生素C、维生素B9、维生素E、钙、锌、铜、铁等微量元素具有抗炎、抗氧化作用,在牙周炎和龋齿的发生发展中起重要作用。患有慢性炎症性肠病的人,以及儿童、孕妇和哺乳期妇女,通常缺乏这些维生素,因此往往容易在口腔软组织发生炎症性变化、牙周炎和龋齿。

Introduction: Orthodontic anomalies are very common both in the world and in our country. The etiology of orthodontic anomalies is multifactorial, complex and conditioned by numerous genetic and non-genetic factors: endogenous and exogenous. Prevention of orthodontic anomalies is possible if we have an insight into the most common etiological factors. Goal: To assess the frequency of individual etiological factors and assess the overall risk of orthodontic anomalies in children in suburban environments. Materials and methods: The research was conducted on 115 children, first grade elementary school pupils (28.68% of all 1st grade students), average age of 6.8 years, from 4 settlements around Novi Sad: Kisač, Kać, Veternik, and Futog. The research was conducted in the form of anonymous rounding surveys for parents with a preliminary explanation of the questions asked. The questions included etiological factors for the occurrence of orthodontic anomalies (diseases in pregnancy, childbirth, breastfeeding, supplementation and feeding, type of pacifier, position of the bottle when eating, bad habits, position when sleeping, position of arms when sleeping in relation to the jaw, pillow height, mouth breathing, orthodontic anomalies in parents). Results: Results indicate the following etiological factors as the most common: supplementary feeding and bottle feeding (in 41.74% of cases), breastfeeding from 0 to 6 months (40.87% of respondents) and mouth breathing (in 24.35% of children). In the examination of the total risk for orthodontic anomalies, low-risk was found in 95.65% of cases, medium-risk in 4.35% (in Kisac 9.38%, in Kać 2.94%, in Veternik 4.35%, in Futog 0% of children), while there were no high-risk respondents. Conclusion: Preventive measures should be aimed at educating mothers about the need and benefits of a natural way of breastfeeding and of using a spoon for supplementation and feeding.
导读:正畸畸在国内外都很常见。正畸的病因是多因素的,复杂的,受许多遗传和非遗传因素的影响:内源性和外源性。如果我们了解最常见的病因,预防正畸是可能的。目的:评估郊区儿童正畸畸的个体病因频率及整体风险。材料和方法:研究对象为115名儿童,小学一年级学生(占所有一年级学生的28.68%),平均年龄6.8岁,来自诺维萨德周围的4个定居点:kisasa、kaki、Veternik和Futog。该研究以匿名四舍五入调查的形式对家长进行,并对所问问题进行初步解释。问题包括正畸发生的病因(怀孕、分娩、母乳喂养、补充和喂养中的疾病、安抚奶嘴类型、进食时奶瓶的位置、不良习惯、睡觉时的姿势、睡觉时手臂的位置与下巴的关系、枕头高度、口腔呼吸、父母的正畸异常)。结果:最常见的病因为辅助喂养和奶瓶喂养(占41.74%)、0 ~ 6月龄母乳喂养(占40.87%)和口呼吸(占24.35%)。在正畸畸总风险检查中,低风险占95.65%,中风险占4.35% (Kisac为9.38%,kaki为2.94%,Veternik为4.35%,Futog为0%),无高危应答者。结论:预防措施应旨在教育母亲自然母乳喂养和使用勺子补充和喂养的必要性和益处。

Background: Premixedcalcium silicate-based sealers are ready-to-use, injectable materials with advantageous biological properties that create environment favorable for periapical tissues repair and health. The aim of our study was to examine the radiopacities of premixed calcium silicate-based sealers:TotalFill BCSealer, EndoSequence BC Sealer, Ceraseal, Bio-C Sealer and to compare them with epoxy-basedsealer, AH Plus. Material and methods: Three specimens (2 mm thick and 5 mm in diameter) of each sealer were radiographed using charge-coupled device-baseddigital sensor (Trophy Radiology, Cedex, France) along with an aluminum stepwedge reference.For radiopacity determination, a graph of the logarithm of aluminum thickness versus radiographic density was plotted and a calibration curve was generated. Radiopacities were assessed from the graph and presented as millimeters of aluminum per millimeter of material (mmAl).ANOVA with a post hoc Tukey test was used for statistical analysis and significance was set at 0.05. Results: Radiopacity values of EndoSequence BC Sealer and Bio-C Sealerwere significantly lower than radiopacities of Ceraseal and AH Plus. Differences in values between EndoSequence BC Sealer and Bio-C Sealer as well as between Ceraseal and AH Plus were nonsignificant. TotalFill BC Sealer was nonsignificantly different from all other sealers. Conclusion: Premixed calcium silicate-based endodontic sealers evaluated in our study had radiopacity values higher than 9 mmAl, in ascending order,from Bio-C Sealer, EndoSequence BC Sealer, TotalFill BC Sealer to Ceraseal.
背景:预混硅酸钙基密封剂是一种即用型可注射材料,具有良好的生物特性,可为根尖周组织修复和健康创造有利的环境。我们研究的目的是检查预混硅酸钙基密封剂(TotalFill BCSealer, EndoSequence BCSealer, Ceraseal, Bio-C Sealer)的放射不透明,并将它们与环氧基密封剂AH Plus进行比较。材料和方法:使用基于电荷耦合器件的数字传感器(Trophy Radiology, Cedex,法国)对每个密封件的三个标本(2mm厚,5mm直径)进行x线摄影,并使用铝阶梯楔作为参考。为了确定射线不透明度,绘制了铝厚度对射线照相密度的对数图,并生成了校准曲线。从图中评估放射不透明度,并以每毫米材料的铝毫米(mmAl)表示。采用方差分析和事后Tukey检验进行统计分析,显著性为0.05。结果:EndoSequence BC Sealer和Bio-C Sealer的放射不透明值明显低于Ceraseal和AH Plus的放射不透明值。EndoSequence BC Sealer和Bio-C Sealer之间以及Ceraseal和AH Plus之间的值差异无统计学意义。TotalFill BC封口机与所有其他封口机无显著差异。结论:在我们的研究中评估的预混硅酸钙基根管密封剂的放射不透明度值高于9mal,从Bio-C密封剂、EndoSequence BC密封剂、TotalFill BC密封剂到Ceraseal。

The basis of the problem: Cemento-ossifying fibroma is a benign fibro-osseous lesion of the jaw. It presents as a slow growing swelling which progressively enlarges if not surgically intervened. Cemento-ossifying fibroma revolves around the use of different terminologies and diagnostic criteria in proposing a strategic treatment plan. Method: The current article describes a rare occurrence of cement-ossifying fibroma affecting maxilla in a 44 year old female patient. Clinically, the lesion was painless and slow growing in nature. Computed tomography revealed a hypodense area in the right posterior maxilla measuring 19.07mm X 27.11mm. The lesion was surgically resected under general anesthesia and it was histopathologically confirmed to be cemento-ossifying fibroma. Results: Total enucleation/ resection of the osseous lesion must be timely ensured to prevent recurrence and also to achieve good prognosis which was done in the described case report. No recurrence was reported in the present case which had a follow up for 24 months. Conclusion: Although numerous controversies exist in the use of terminologies, a multi centric approach mandates to correlate clinically, radiographically and histologically to determine the treatment perspective.

Bioaerosol in dental prosthodontics 生物气雾剂在口腔修复中的应用
Q4 Dentistry Pub Date : 2020-01-01 DOI: 10.5937/ASN2082106J
G. M. Jovanović
Introdution: During many dental interventions, performed using handpiece instruments and pusters, an aerosol is created,which is converted into a bioaerosol (BIOA) by mixing with the particles of various organic components from the patient's oral cavity.When the high-speed mashine is started, the air becomes instantly contaminated and practically covers the entire room. Pollution is registered all the times, as well as after prosthetic treatment. BIOA created during prosthetic workcontains various bacteria, fungi and viruses from the patient's oral cavity. These microorganisms pose a real hazard to health workers and are a potential risk for infection. The most common pathogens include influenza viruses, herpes viruses, as well as pathogenic streptococci and staphylococci. Infectious diseases, biosynosis, acute toxic reactions, allergies, atopic diseases, conjunctivitis, contact dermatitis, infections of the respiratory system, and even some types of cancer, are possible manifestations of side effects of BIOA. Conclusion:BIOA poses a potential danger to contamination of air, work surfaces and objects in dental offices. Direct and indirect exposure of dental staff and patients to BIOA is especially pronounced in the conditions of COVID 19. Although it is impossible to completely eliminate the risk of adverse effects of BIOA, it is important to pay attention to all prevention measures that can reduce the likelihood of contamination.
简介:在许多牙科干预中,使用手持器械和宣传单,产生一种气溶胶,通过与患者口腔中各种有机成分的颗粒混合,将其转化为生物气溶胶(BIOA)。当高速机器启动时,空气立即被污染,几乎覆盖了整个房间。污染一直被记录下来,以及修复后的污染。在修复过程中产生的BIOA含有来自患者口腔的各种细菌、真菌和病毒。这些微生物对卫生工作者构成真正的危害,是潜在的感染风险。最常见的病原体包括流感病毒、疱疹病毒以及致病性链球菌和葡萄球菌。传染病、生物麻痹、急性毒性反应、过敏、特应性疾病、结膜炎、接触性皮炎、呼吸系统感染,甚至某些类型的癌症,都是BIOA副作用的可能表现。结论:BIOA对牙科诊所空气、工作表面和物品的污染具有潜在的危险。在COVID - 19的情况下,牙科工作人员和患者直接和间接暴露于BIOA尤其明显。虽然不可能完全消除BIOA不良影响的风险,但重要的是要注意所有可以减少污染可能性的预防措施。

Introduction: Aesthetic smile is an important part for every patient since it plays a vital role in his personality, selfconfidence and self-esteem. Aim: To assess the relationship between the potential factors affecting the perception of aesthetic smile among adult patients, to evaluate the patient's satisfaction toward their smile and to find the most common factors for their dissatisfaction caused by smile. Materials and methods: A 100 males and 100 females were evaluated for the presence or absence of aesthetic smile. The clinical examination was included categories related to personal aesthetic factors of the smile. A questioner designed by Goldstein to measure the patient's self-perception and satisfaction of their smiles was used. The data were pooled for analysis, statistical significance was set to p-value ˃ 0.05. Results: There was a significant differences in the parallel interpupillary line and coincided of dental midlines alone and with facial midlines in the aesthetic and non-aesthetic choices, also between the symmetry of maxillary central and lateralicisors, and canines with their axial inclinations choices (p< 0.05). Some group of questions showed significant differences among female and male subjects while, the male subjects Some questions were near to the statistical significant differences, while others showed no significace between males and females choices. Conclusion: Dental and facial factors showed highly significant relationship with aesthetic smile. So, it should be observed by a dental specialist to provide a proper treatment plan with respect to the potential factors of the aesthetics to help for self-satisfaction measurement.
