The objective of this study was to evaluate the effect of different surface treatments on the pigmentability of the ceramic after immersion in staining solution. 44 disks of 10 mm radius and 3 mm thickness were made. Samples were randomly assigned among 4 experimental groups (n=11) receiving surface treatment according to the different groups M, H, B, L. (n=10) were distributed for color evaluation and Roughness (RU) and a sample of each group used for scanning electron microscopy (SEM) analysis. For (RU), the data were subjected to ANOVA on ranks (α=0.05), and for the color ANOVA a factor (α=0.05). In the microphotographs of the surface, a qualitative/descriptive analysis was carried out. Results: In the (RU) compared before and after immersion for each group, no statistical difference was observed (p> 0.05). When comparing the types of polish before immersion, a difference was observed between the L group with the other M, H, B (p <0.05). In the analysis of the groups after immersion, there was a difference of group L with B and M (p <0.05). When comparing the color alteration, after immersion, there was a difference between all the ANOVA groups (p <0.05). In the analysis by (SEM) all groups had partially porous surfaces; however, the varnishes produced the best result groups H and B.The texture of the surface is an important factor in the pigmentability of ceramics. the varnished materials showed less color alteration.
本研究的目的是评估不同表面处理对浸泡在染色溶液中的陶瓷可着色性的影响。制作了44个半径为10mm、厚度为3mm的圆盘。根据不同的组M、H、B、L,将样品随机分配到接受表面处理的4个实验组(n=11)中。(n=10)用于颜色评估和粗糙度(RU),每组的样品用于扫描电子显微镜(SEM)分析。对于(RU),对数据进行秩方差分析(α=0.05),对颜色方差分析进行因子分析(α=0.05)。在表面的显微照片中,进行了定性/描述性分析。结果:在浸泡前后各组的(RU)比较中,没有观察到统计学差异(p>0.05)。在比较浸泡前抛光剂的类型时,L组与其他M、H、B组之间有差异(p<0.05)。在浸泡后各组的分析中,浸泡后各组间差异有统计学意义(p<0.05),扫描电镜分析各组表面均为部分多孔;然而,H组和B组的清漆产生了最好的结果。表面的纹理是陶瓷可着色性的一个重要因素。涂漆材料的颜色变化较小。

Objective: To determine the effect of dental caries on the quality of life of pre-school children. Materials and methods: The present was an observational, correlational, cross-sectional and prospective study in which 200 parents participated, who filled the ECOHIS questionnaire. Children were clinically evaluated using the ICDAS diagnostic criteria by a single examiner calibrated by a gold-standard, presenting an inter and intra-examiner Kappa of 0.79 and 0.81 respectively. The statistical analysis used was Chi square. Results: The impact of dental caries on quality of life using the ECOHIS questionnaire was considered intermediate. The parents' educational level did not show to be a variable that influenced their perception, and there were no statistically significant differences (p = 0.53). Regarding the prevalence of dental caries according to the ICDAS criterion was 94% if the WHO criteria is applied 82% of children showed dental caries. The mean d3-6mf-t of the population was 5.05, confirming that the disease was present in a high number of the examined children aged 3 to 5 years. Conclusions: Despite a high prevalence of dental caries in children, this condition had a medium impact on their Oral Health Related Quality of Life, according to the perception of their parents.
目的:探讨龋齿对学龄前儿童生活质量的影响。材料和方法:本研究是一项观察性、相关性、横断面和前瞻性研究,共有200名家长参与,他们填写了ECOHIS问卷。由金标准校准的单一检查者使用ICDAS诊断标准对儿童进行临床评估,检查者间和检查者内Kappa分别为0.79和0.81。采用卡方统计分析。结果:使用ECOHIS问卷,龋齿对生活质量的影响被认为是中等的。父母的教育水平并不是影响他们认知的变量,也没有统计学上的显著差异(p=0.53)。如果采用世界卫生组织标准,根据ICDAS标准,龋齿的患病率为94%,82%的儿童患有龋齿。该人群的平均d3-6mf-t为5.05,证实该疾病存在于大量3至5岁的受检儿童中。结论:尽管儿童龋齿患病率很高,但根据父母的看法,这种情况对他们的口腔健康相关生活质量有中等影响。

Fibróma traumático en cavidad oral – una revisión 口腔外伤性纤维化-综述
Pub Date : 2019-01-10 DOI: 10.24265/KIRU.2019.V16N1.07
Marco Antonio Rocafuerte-Acurio
The intraoral fibrous growth of the soft tissues is relatively common and may be benign reactive or a neoplastic lesion. Among these localized fibrous growths, it has been found that traumatic fibroma is the most common in the oral cavity. The traumatic fibroma is a reactive fibrous hyperplasia caused by trauma or local irritation, such as the presence of calculus, overhanging margins of restorations, orthodontic appliances, among others. This pathology is also known as irritation fibroma, inflammatory fibroma, focal fibrous hyperplasia, fibrous nodule and fibrous polyp. It can occur anywhere in the oral cavity but it is more frequently seen in the buccal mucosa or along the occlusal plane. Traumatic fibroma is a common lesion in the oral cavity. Therefore, a wide knowledge about this injury would be useful for dentists in the treatment of their patients.
口腔内软组织纤维生长相对常见,可能是良性反应性或肿瘤病变。在这些局部纤维生长中,创伤性纤维瘤在口腔中最为常见。外伤性纤维瘤是由外伤或局部刺激引起的反应性纤维增生,如结石、修复体边缘悬垂、正畸矫治器等。这种病理也被称为刺激性纤维瘤、炎性纤维瘤、局灶性纤维增生、纤维结节和纤维息肉。它可以发生在口腔的任何地方,但它更常见于颊粘膜或沿咬合平面。外伤性纤维瘤是口腔中一种常见的病变。因此,对这种损伤的广泛了解将有助于牙医治疗他们的病人。

Objective: Objective: To determine the relationship between the variation of salivary pH by the consumption of industrialized fruit juices and gingival health in children of the Educational Institution (I.E.) "Isabel La Catolica". Material and Method : This is an observational, analytical, cross-sectional study. We evaluated 108 children of both sexes, aged 6 to 8 years. The sample was divided into two groups, a study group that drank industrialized fruit juices and a control group that drank water. A basal salivary pH measurement was performed for both groups with a digital pH meter, and after drinking the industrialized fruit juice or water, it was measured again at intervals of 5 and 10 minutes. The gingival condition was evaluated by Loe Silness Gingival Index and PMA Index. Results : No correlation was found between the Loe Silness Gingival Index and the salivary pHin both groups, p> 0.05. In the study group, basal salivary pH was slightly acidic and a greater fall in pH was observed after 5 minutes of consuming fruit juice, p <0.001. An inverse correlation was found between the gingival index and the salivary pH, in the control group, with a higher gingival index, lower salivary pH. The gingival index in the study group was moderate and in the mild control group. Conclusions : There is no correlation between the gingival health of the children evaluated and the salivary pH associated with the consumption of industrialized fruit juices.
目的:了解“Isabel La Catolica”教育机构儿童饮用工业化果汁后唾液pH值的变化与牙龈健康之间的关系。材料和方法:这是一项观察、分析、横断面研究。我们评估了108名6至8岁的男女儿童。样本被分为两组,一组饮用工业化果汁,另一组饮用水。用数字pH计对两组进行唾液基本pH测量,在饮用工业化果汁或水后,每隔5分钟和10分钟再次测量。采用Loe-Silness牙龈指数和PMA指数评价牙龈状况。结果:两组患者的Loe-Silness牙龈指数与唾液pH值无相关性,p>0.05。在研究组中,唾液的基础pH为微酸性,在饮用果汁5分钟后,观察到pH下降幅度更大,p<0.001。在对照组中,牙龈指数与唾液pH值呈负相关,牙龈指数较高,唾液pH值较低。研究组的牙龈指数为中度,轻度对照组为中度。结论:所评估的儿童牙龈健康与食用工业化果汁相关的唾液pH值之间没有相关性。

Endodontic therapy seeks to maintain natural dentition's integrity in form function and aesthetics. Accidents during these procedures commonly occur which affect the prognosis of root canal treatment. A furcal perforation is a complication that refers to the mechanical or pathological communication between the pulp chamber and supporting ligament, in the lower area of the pulp chamber and leads to the worst result of the treatment. It can occur during the endodontic access or during the preparation of an intraradicular retainer, although it can also be due to caries lesions of root absorption. For long term success, perforations should be repaired as soon as possible with a biocompatible material any delay causes bacterial contamination and leads to complicated periodontal endodontic lesions. An ideal perforation repair material , should create an adequate seal, be biocompatible, not be affect by blood contamination, be a bactericide, radiopaque, induce bone formation and healing, induce mineralization, cementogenesis, facilite its manipulation and application. Various materials have been used to repair furcal perforations including MTA and Biodentine. The objective of this study is to carry out a review of the literature about the sealing capacity of MTA and Biodentine in the repair of furcal perforations. To reach this objective a bibliographic review is carried out in the leading odontological databases and magazines and articles are chosen according to their scientific validity their relationship with the topic and the year of publication wich stretches from 2009 to 2018.
牙髓治疗旨在保持自然牙列在形态、功能和美观方面的完整性。这些手术过程中经常发生事故,影响根管治疗的预后。分叉穿孔是一种并发症,指的是髓室和支撑韧带之间在髓室下部区域的机械或病理连通,并导致最差的治疗结果。它可能发生在根管进入过程中或根内固定器的制备过程中,尽管它也可能是由于根吸收的龋齿损伤。为了获得长期成功,应尽快用生物相容性材料修复穿孔。任何延迟都会导致细菌污染,并导致复杂的牙周牙髓病变。理想的穿孔修复材料应具有足够的密封性、生物相容性、不受血液污染影响、杀菌剂、不透射线、诱导骨形成和愈合、诱导矿化、牙骨质形成、促进其操作和应用。各种材料已被用于修复毛发穿孔,包括MTA和生物牙本质。本研究的目的是对MTA和生物牙本质在修复牙龈穿孔中的密封能力的文献进行综述。为了实现这一目标,在领先的牙病数据库中进行了文献综述,并根据其科学有效性选择杂志和文章——它们与主题的关系以及2009年至2018年的出版年份。

Objective: Due to the high rate of dental caries in our country, and specifically in the SERODU Clinic, we sought to determine the prevalence of this pathology in permanent first molars, in children aged 6 to 9 years who attended the Clinic of the Faculty of Dentistry from the Equatorial Technological University-Quito-Ecuador and to know which of the first permanent molars has the highest exposure of dental caries, in which gender is more predominant and if there was any previous, preventive or restorative treatment. Materials and methods: An observational, retrospective and descriptive study was conducted in the Clinic of the Faculty of Dentistry of the Technological University Equinoccial-Quito-Ecuador, during the period 2016-2017, reviewing each of the Clinical Histories entered in the interval of proposed time, with a previously calibrated staff. In History the information of the Odontogram and the Treatment section was collected. They met the inclusion and exclusion requirements previously proposed. Results: Of a total of 57 reviewed clinical histories, 44 patients did not present dental caries, while the rest did present the pathology. Sealants being the treatment of choice as prevention in these parts Conclusions: A higher prevalence of dental caries was observed in the first permanent molars of the upper arch. The first upper left molar was the most affected tooth for both genders. The most predominant treatment was the preventive specifically the application of sealants, in both genders.
摘要目的:由于我国龋齿率高,特别是在SERODU诊所,我们试图确定的流行病理学在永久第一磨牙,在6到9岁的儿童参加的诊所牙科学院从赤道技术University-Quito-Ecuador和知道的第一恒磨牙接触最高的龋齿,性别更主要,如果有任何之前,预防性或恢复性治疗材料和方法:2016-2017年期间,在基多-厄瓜多尔科技大学Equinoccial-Quito-Ecuador牙科学院的诊所进行了一项观察性、回顾性和描述性研究,在预先校准的工作人员的指导下,回顾了在拟议时间间隔内输入的每个临床病史。在历史上收集牙周摄影和治疗部分的资料。他们符合先前提出的纳入和排除要求。结果:在57例临床病史中,44例患者没有龋齿,其余患者有龋齿病理表现。结论:上牙弓第一恒磨牙龋发病率较高。左上第一磨牙是男女中受影响最严重的牙齿。在两性中,最主要的治疗是预防性的,特别是应用密封剂。
