Objectives. Analysis of a group with oral rehabilitation patients with different types of fixed protected restorations, to correlate the therapeutic success rate with the type of aggregation of restorations and with the materials used to fabricate them. Material and methods. The study material was represented by the medical records of one group of the patients with various types of partial edentation. The interest data were collected and were processed with Microsoft Excel statistics from the Office 365 package. Results. The group included: 162 patients (59.56%) with 182 fixed prosthetic restorations with teeth aggregation (of which 106 metal-ceramic restorations, 33 metal-composite restorations, 22 restorations from zirconium with ceramic and 21 all-ceramic restorations) and 110 patients (40.44%) with 140 fixed prosthetic restorations with implant aggregation (72 metal-ceramic restorations, 5 metal-composite restorations, 36 zirconium-ceramic restorations and 27 all-ceramic restorations). Complications detected 3 years after the completion of prosthetic treatment were classified into biological and technical complications. Discussions. In the analyzed group, the metal-ceramic prosthetic restorations were numerically superior to those of integral ceramics or zirconium oxide and ceramics, but we also noticed the presence of metal-composite restorations, preferred by certain categories of patients for economic reasons. In our study we identified 21 technical complications and 19 biological complications. Conclusions. In the group analyzed retrospectively, the therapeutic success rate at 3 years was 87.58%. Metal-ceramic restorations were the main way of rehabilitation applied to edentulous patients. Metal-composite restorations had the highest percentage failure rate, and all-ceramic restorations had the lowest percentage failure rate. The failure rate for prosthetic restorations with teeth aggregation was 14.83%, and the failure rate for restorations with implant aggregation was 9.29%. In order to validate the results obtained, it is necessary to extend the study to larger groups of patients, dispensed for longer periods of time.
目标。对一组具有不同类型固定保护修复体的口腔康复患者进行分析,以将治疗成功率与修复体的聚集类型和制造材料相关联。材料和方法。研究材料以一组患有各种类型部分牙列缺失的患者的病历为代表。兴趣数据是从Office 365软件包中收集并使用Microsoft Excel统计数据进行处理的。后果该组包括:162名患者(59.56%),182个具有牙齿聚集性的固定修复体(其中106个金属陶瓷修复体,33个金属复合修复体,22个锆陶瓷修复体和21个全陶瓷修复体)和110名患者(40.44%),140个具有种植体聚集性的固定修复体(72种金属陶瓷修复体,5种金属复合修复体,36种锆陶瓷修复体和27种全陶瓷修复体)。假体治疗完成3年后发现的并发症分为生物学并发症和技术并发症。讨论。在分析组中,金属陶瓷修复体在数量上优于整体陶瓷或氧化锆和陶瓷,但我们也注意到存在金属复合修复体,出于经济原因,某些类别的患者更喜欢这种修复体。在我们的研究中,我们发现了21种技术并发症和19种生物学并发症。结论。在回顾性分析的组中,3年的治疗成功率为87.58%。金属陶瓷修复体是无牙患者的主要康复方式。金属复合修复体的失败率最高,而所有陶瓷修复体的成功率最低。具有牙齿聚集的修复体的失败率为14.83%,具有种植体聚集的修复物的失败率是9.29%。为了验证所获得的结果,有必要将研究扩展到更大的患者群体,并在更长的时间内进行分配。

The clinical applications of oral mucosal biomechanics are particularly important in determining how stimulation can be performed for tissue remodeling, in understanding the level of pressure that can be applied to the painful threshold, in osseous resorption, and the availability of tissue movement. This study shows, through the finite element, the way in which the periodontal ligament behaves at the level of all dental surfaces in nonlinear model and 3 levels of alveolar bone retraction (0 %, 50%, 75%). From the point of view of geometric construction, each model consists of 3 independent components: the alveolar bone, the periodontal ligament (PL) and the tooth. The deformities on the lingual surface are very small compared to the other surfaces. The deformity increases progressively with the loss of the supporting bone. From a physiological point of view, the nonlinear model is much closer to reality because it simulates the reaction of the tissue to its immediate loading by a very low rigidity after which, due to the hydrostatic pressure created in the interstitial fluid, the value of tissue rigidity increases exponentially.
口腔粘膜生物力学的临床应用在确定如何对组织重塑进行刺激、理解可应用于疼痛阈值的压力水平、骨吸收和组织运动的可用性方面尤为重要。本研究通过有限元显示了非线性模型中牙周膜在所有牙面水平和牙槽骨内缩3个水平(0%、50%、75%)的行为方式。从几何结构上看,每个模型由3个独立的部分组成:牙槽骨、牙周韧带(PL)和牙齿。与其他表面相比,舌表面的畸形非常小。随着支撑骨的丧失,畸形逐渐增加。从生理学的角度来看,非线性模型更接近现实,因为它模拟了组织对其即时载荷的反应,其刚度很低,之后,由于间质液中产生的静水压力,组织刚度值呈指数增长。

Introduction. The aim of this study was to assess the results of the impact of the first year of the COVID-19 (coronavirus disease 19) pandemic on the postgraduate hybrid educational process (virtual/e-learning and traditional) from a resident-centred perspective, in a group of general dentistry resident doctors. Materials and methods. A questionnaire with 32 items (Q1-Q32) was configured using Google Forms and filled online, anonymously. In the first section, demographic information was collected. The other sections collected data about: 1) technical support), 2) the impact of traffic restriction and self-isolation, 3) the impact of preclinical/clinical online training compared to the on-site one, 4) attendance of online theoretical courses, 5) the effect of preclinical training in laboratories, 6) the degree of online interactivity and 7) general satisfaction. Excepting demographics and Q1-Q3 items, all other parts used multi-choice responses based on a five-degree Likert scale. Results. Most resident doctors did not report any problem in connection to online courses, increased anxiety, troubled concentration, or decreased learning efficiency. Conclusions. Resident doctors considered part-time e-learning process as a viable approach capable of providing a qualitative education and that the reorganization of the preclinical activity allowed them to carry out more precise and efficient procedures in the clinic.

Tempting and disturbing by its purpose to correct dental malocclusions, but also asymmetries facial expressions, to shape smiles and to improve the quality of life, orthodontics has experienced a permanent dynamics in recent decades both by improving the means of diagnosis (digitization) as well as the introduction of increasingly high-performance materials: hybrid springs, mini-implants etc. An important diagnostic element in Orthodontics is photography made from the front and profile, which is also a forensic document, on which a series of angular and linear parameters are analyzed at the beginning and end of the treatment. Orthodontic diagnostic pictures are a non-invasive method of diagnosis and are made in the natural position of the head NHP, which is a standardized, reproducible position of the head in space where the subject is looking at a distant point of the eye level. The angular and metric values on the photo or teleradiography of the face/profile are essential elements in both establishing a diagnosis and the treatment plan that will aim to achieve a balanced face and a harmonious profile. These values can be transferred to the computer, and with the help of specialized software will be analyzed and interpreted for each clinical case. This study aimed to perform a comparative analysis of four angles that define the facial profile in a group of 30 patients (15 females and 15 males) patients aged 18-24 years with Angle I class malocclusions and bone growth finished. The values were measured on the profile photograph (after tracing the anthropometric points with an eye pencil) and statistically evaluated for both sexes, and the photos were scanned and important in the DSD software so that the same angles can be evaluated digitally. Digital orthodontics tends to take up more and more space in the assessment of an orthodontic case. In orthodontic treatments, the thickness of the soft parts that can compensate for an unsightly profile of the bone relief is taken into account.
为了矫正牙齿错颌、不对称的面部表情、塑造微笑和提高生活质量,正畸学在最近几十年里经历了一个永久的动态,无论是通过改进诊断手段(数字化),还是引入越来越高性能的材料:混合弹簧、微型植入物等。正畸学的一个重要诊断要素是从正面和侧面拍摄的照片,这也是一种法医文件,在治疗开始和结束时分析一系列角度和线性参数。正畸诊断图片是一种非侵入性的诊断方法,是在头部NHP的自然位置拍摄的,NHP是头部在空间中的一个标准化的、可重复的位置,受试者正看着眼睛水平的远处点。面部/侧面的照片或远程放射照相的角度和度量值是建立诊断和治疗计划的基本要素,旨在实现平衡的面部和和谐的侧面。这些值可以传输到计算机中,并在专业软件的帮助下对每个临床病例进行分析和解释。本研究的目的是对30例(15名女性和15名男性)年龄在18-24岁的I角型错颌和骨生长完成的患者进行四个角度的面部轮廓的比较分析。这些值是在侧面照片上测量的(在用眼线笔追踪人体测量点之后),并对男女进行统计评估,照片在DSD软件中进行扫描和重要处理,以便对相同的角度进行数字评估。数字正畸在正畸病例的评估中占据越来越多的空间。在正畸治疗中,要考虑到软性部分的厚度,以补偿不美观的骨浮雕轮廓。

The worldwide high prevalence, alongside both modifiable and unmodifiable risk factors and local causal factors of the periodontal disease lead to bone and periodontal gum attachment loss. It is not considered a systemic disease but there are pathological influences between general diseases such as diabetes mellitus and periodontal disease. Anxiety of dental settlement is a main factor that prevent patients from addressing to a regular follow-up or, worse, to obtain the personalized treatment from the beginning of dental conditions. We present a case of a 24-year-old male that postponed his presentation to dentist until pain prevented him from a proper sleep. He required a complete history and clinical examination in order to identify his dental emergency and, also, the dentist anxiety he developed during his lifetime. His management required a complex treatment, fractioned in multiple session, in order to help him overcome his anxiety and to obtain a good outcome. The case particularity include the lack of proper oral hygiene, due to the acute and/or chronic pain that the patient encountered, alongside with the fear of the dentist and the dental office, that delayed the presentation to a specialist to the moment when pain was unbearable and represented a medical emergency.
牙周病在世界范围内的高患病率,以及可改变和不可改变的危险因素和局部因果因素导致骨和牙周牙龈附着丧失。它不被认为是一种全身性疾病,但在一般疾病如糖尿病和牙周病之间有病理影响。焦虑的牙齿解决是一个主要因素,阻止患者解决定期随访,更糟的是,获得个性化的治疗,从牙病开始。我们提出一个病例24岁的男性推迟他的表现,以牙医,直到疼痛使他无法正常睡眠。他需要一份完整的病史和临床检查,以确定他的牙齿紧急情况,以及他一生中出现的牙医焦虑。他的治疗需要复杂的治疗,分多次治疗,以帮助他克服焦虑并获得良好的结果。病例特殊性包括由于患者遇到的急性和/或慢性疼痛以及对牙医和牙科诊所的恐惧而缺乏适当的口腔卫生,这推迟了向专家就诊的时间,直到疼痛无法忍受并代表医疗紧急情况。

Diabetes mellitus and periodontal disease 糖尿病和牙周病

Diabetes mellitus (DM) is a chronic non-transmittable disease and, alongside periodontal disease, another chronic disease, but with infectious and inflammatory etiology, that have increasing prevalence. The link between the two comorbidities is bidirectional, with common aspects such the inflammatory state, altered immune response and healing process. This link is alimented, also, by oxidative stress, an element that can initiate proinflammatory pathways in both pathologies. Moreover, periodontal disease favors the development of DM complications by a multifactorial mechanism centered on hyperglycemia, that leads to damage of the endothelial vascular cells, characteristic for microvascular complications, while the periodontal bacteria and their waste products, and inflammatory cytokines lead to an increase in systemic inflammation and damage of the vascular walls that aggravates the atherogenic process. The increase of novel cases of type 2 DM or gestational DM in patients with periodontitis has no sufficient data. Dental caries is favored by DM and not by periodontal disease. So, DM is a well-known risk factor for periodontal disease and, on the other hand, periodontitis influences the metabolic control and favors the development of DM complications, but with a link between these conditions that is not fully understood. Other comorbidities, such as missing teeth, depression, osteoporosis are, also, positively associated to higher risk of development for periodontal disease. Patients with DM should be regularly screened for periodontal disease and referred to therapy if necessary, while the patients with periodontal disease should be screened for the presence of DM.
糖尿病(DM)是一种慢性非传播性疾病,与牙周病一样,也是另一种慢性疾病,但其病因具有传染性和炎症性,患病率越来越高。这两种合并症之间的联系是双向的,有共同的方面,如炎症状态、免疫反应改变和愈合过程。这种联系也受到氧化应激的支持,氧化应激是一种在两种病理中都能启动促炎途径的元素。此外,牙周病通过以高血糖为中心的多因素机制有利于糖尿病并发症的发展,导致内皮血管细胞的损伤,这是微血管并发症的特征,而牙周细菌及其废物,炎性细胞因子导致全身炎症和血管壁损伤的增加,从而加剧动脉粥样硬化过程。牙周炎患者中新型2型糖尿病或妊娠期糖尿病病例的增加没有足够的数据。糖尿病患者喜欢龋齿,而牙周病患者不喜欢龋齿。因此,糖尿病是牙周病的一个众所周知的风险因素,另一方面,牙周炎影响代谢控制并有利于糖尿病并发症的发展,但这些疾病之间的联系尚不完全清楚。其他合并症,如缺牙、抑郁症、骨质疏松症,也与牙周病的高风险呈正相关。糖尿病患者应定期筛查牙周病,必要时转诊治疗,而牙周病患者应筛查是否存在糖尿病。

The case of a 69-years-old patient with flared anterior teeth (bi-pro-alveolar position with loose of contact points) secondary to periodontitis, was resolved by combining alveolar maxillary preservation with orthodontic treatment to correct the alveolar axes of the mandibular incisors. All mandibular teeth were finally removed but the implants could be placed in the correct antero-posterior tilt axes. The temporary maxillary prosthesis was a removable one under conditions of a thin gingival biotype. The final result meant the correction of the profile and a good preservation of the minimally keratinized gingiva around implants.
一例69岁的患者因牙周炎继发于前牙张开(双前牙槽位置,接触点松动),通过将牙槽-上颌保护与正畸治疗相结合来矫正下颌切牙的牙槽轴,从而解决了这一问题。所有下颌牙齿最终都被摘除了,但植入物可以放置在正确的前后倾斜轴上。临时上颌假体是在薄牙龈生物型条件下可移除的。最终的结果意味着轮廓的矫正和种植体周围最小角化牙龈的良好保存。

Preterm infants are a special category of patients known for high rates of associated morbidities. This morbidities range from breathing problems to motor and neurologic impairments. The survival rates are improving along with better neonatal care, but the effects of preterm birth can still be seen in this category in patients. Even though dental health problems are not a largely debated subject, one should take into consideration that teeth, like other tissues are influenced by prematurity, and preterm babies are more likely to develop dental problems.
早产儿是一类特殊的患者,以其高发病率而闻名。这种疾病的范围从呼吸问题到运动和神经损伤。随着新生儿护理的改善,存活率正在提高,但在这类患者中仍然可以看到早产的影响。尽管牙齿健康问题并不是一个备受争议的话题,但人们应该考虑到,牙齿和其他组织一样,也会受到早产的影响,早产儿更容易出现牙齿问题。

Aim. To evaluate the reasons for seeking dental care for children and teenagers attending an emergency clinic and the proportion of single visits treatments. Material and methods. A retrospective study was made on 500 children and teenagers (252 girls), mean age 13.91±2.3 years, who attended the emergency office from the Paedodontics Department of "Carol Davila" University of Medicine and Pharmacy, Bucharest, during 2017-2019. Information regarding age/gender/diagnosis and treatment were analyzed. Statistical analysis included descriptive statistics and Pearson's Chi-square test with the significance level set as p < 0.05. Results. For 401 children (80.2%), pain was the main reason for the presentation in an emergency visit. 11% came for a specialist consultation and the others 8.8% because of a dental trauma. Nearly 79% of the visits were due to caries: 39% simple decays and 40% complicated caries. Of the decayed teeth, 62.8% were on the posterior teeth and 37.2% on the anterior permanent teeth. Only 15.4% needed one single visit treatment, the others needed a complex pulp therapy. Conclusions. Pain caused by dental decay was the most frequent chief complaint. A lot of children were brought to the dentist with complaints that had started long time before, for which over-the-counter medications had been used. Most children had complicated caries which requires multiple treatment sessions.
目标评估在急诊诊所就诊的儿童和青少年寻求牙科护理的原因以及单次就诊治疗的比例。材料和方法。一项回顾性研究对2017-2019年布加勒斯特“Carol Davila”医学与药学大学口腔科急诊室就诊的500名儿童和青少年(252名女孩)进行了研究,他们的平均年龄为13.91±2.3岁。分析了有关年龄/性别/诊断和治疗的信息。统计分析包括描述性统计和皮尔逊卡方检验,显著性水平设置为p<0.05。后果对于401名儿童(80.2%),疼痛是急诊就诊的主要原因。11%的人来咨询专家,其他8.8%的人是因为牙科创伤。近79%的就诊是由龋齿引起的:39%为单纯龋齿,40%为复杂龋齿。蛀牙中后牙占62.8%,前恒牙占37.2%。只有15.4%的患者需要单次就诊治疗,其他患者需要复杂的牙髓治疗。结论。蛀牙引起的疼痛是最常见的主诉。许多孩子被带到牙医那里,抱怨早就开始了,因为他们使用了非处方药。大多数儿童患有复杂的龋齿,需要多次治疗。

Prenatal ultrasound examination should take place between 18 and 20 week of gestation and is important for early detection of fetal anomalies such as the facial malformations. One important anatomic element is the palate that raises echographic technical difficulties such as the shadowing by facial bones and, especially, by the superior alveolar ridge, the fetal prone position and its localization, respectively, profoundly, inside of fetal head or anatomic obstacles such as the fetal tongue, so new echographic examination techniques are being under evaluation. The prenatal detection rate of fetal cleft palate remains low, so various methods of examination are being proposed. The ultrasound assessment of the fetal face is made by 2D ultrasound, technique completed by 3D ultrasound, which includes the evaluation in both axial and coronal planes, with the uvula being analyzed in two types of section, transversal and sagittal. In the latter to epiglottis is a landmark that confirms the identification of the uvula and a normal uvula has a typical and resembling echographic pattern to the equal sign. Even tough, prenatal diagnosis of soft palate cleft is a real challenge, with low detection rate due to difficulty of its visualization during routine examination, and even if suspected, diagnostic accuracy is low.
产前超声检查应在妊娠18至20周之间进行,这对于早期发现胎儿异常(如面部畸形)非常重要。一个重要的解剖因素是上颚,它增加了超声技术上的困难,如面部骨骼的阴影,特别是上牙槽嵴的阴影,胎儿俯卧位及其定位,分别在胎儿头部内部或解剖障碍,如胎儿舌头,因此新的超声检查技术正在评估中。胎儿腭裂的产前检出率仍然很低,因此人们提出了各种检查方法。胎儿面部的超声评估采用二维超声,技术由三维超声完成,包括轴位和冠状面评估,小舌在横切面和矢状面两种断面上进行分析。在后者会厌是一个标志,确认小舌的识别和一个正常的小舌有一个典型的和类似的超声模式的等号。软腭裂的产前诊断是一项艰巨的挑战,由于常规检查时难以看到,诊断率低,即使怀疑,诊断准确率也很低。
