Pleomorphic adenoma is the most prevalent salivary tumor, 65% of which occur in major glands. This tumor varies in terms of size depending on the gland where it is located. The most common sites of the minor salivary glands are the palate, lips, cheeks, and throat. Palatal pleomorphic adenoma is laterally located, rarely crossing the midline. This tumor is painless with slow growth rate, which often appears in the fourth or fifth decade of life with female predominance. The tumor may enlarge with delayed treatment. This study aimed to present the case of a 51-year-old woman with an oversized mass on the palate (diameters: 8.5x5.5x2.5 cm), which extended from the anterior portion of the hard palate to the soft palate with a slow growth rate within 10 years. The case definition was accompanied by the determined surgical treatment.

Introduction: Temporomandibular joint (TMJ) disorders are among the most prevalent abnormalities of the jaw, which affect the masticatory system, including the muscles, TMJ, and tendons. Clinical examination alone cannot determine the cause of temporomandibular disorder (TMD). In most cases, the cause of TMD and a proper treatment plan are determined based on imaging modalities. The present study aimed to investigate the bone changes in the patients with TMD symptoms using cone beam computed tomography (CBCT). Methods: This retrospective, cross-sectional study was conducted through recording data on the pain caused by TMJ (upon touching, using the TMJ, and maximum mouth opening), clicking, and crepitus using a checklist of clinical symptoms. CBCT images were examined for the associated bone changes, including sclerosis, flattening, erosion, and osteophyte. Data analysis was performed in SPSS version 21 using Chi-square and logistic regression analysis. Results: In total, 160 joint images were examined, including 132 cases of flattening (82.5%), 45 cases of sclerosis (28.12%), 41 cases of osteophytes (25.62%), and 66 cases of erosion (41.25%). A significant association was observed between pain and flattening, and sclerosis and osteophytes. Moreover, a significant correlation was observed between flattening and clicking (P<0.05). Conclusion: According to the results, flattening was the most common bone change in the patients with TMD. In addition, sclerosis had the most significant association with pain, while sclerosis, osteophytes, and erosion were significantly correlated with joint crepitation.
颞下颌关节(TMJ)疾病是颌骨最常见的异常之一，它影响咀嚼系统，包括肌肉、颞下颌关节和肌腱。单纯的临床检查不能确定颞下颌紊乱(TMD)的病因。在大多数情况下，TMD的病因和适当的治疗计划是根据成像方式确定的。本研究旨在利用锥形束计算机断层扫描(CBCT)研究TMD症状患者的骨变化。方法:本研究采用回顾性横断面研究方法，通过临床症状检查表记录TMJ引起的疼痛(触摸、使用TMJ、最大张口时)、咔嗒声和抖音的数据。检查CBCT图像中相关的骨变化，包括硬化、变平、侵蚀和骨赘。数据分析采用SPSS version 21，采用卡方和logistic回归分析。结果:共检查关节图像160张，其中扁平132例(82.5%)，硬化45例(28.12%)，骨赘41例(25.62%)，糜烂66例(41.25%)。在疼痛和扁平化、硬化和骨赘之间观察到显著的关联。压扁与咔哒之间存在显著相关(P<0.05)。结论:骨变平是TMD患者最常见的骨改变。此外，硬化症与疼痛的关联最为显著，而硬化症、骨赘和糜烂与关节震颤的关联最为显著。

Introduction: Dental caries is the most common chronic condition in children. Recently, there has been a growing tendency to using digital panoramic radiography among clinicians. The present study aimed to determine the accuracy of digital panoramic radiography with and without software enhancement in the diagnosis of proximal dental caries in primary molars. Methods: This study was conducted using 27 digital bitewings and panoramic radiography in 2016. Initially, panoramic radiography without enhancement was observed by a maxillofacial radiologist. Afterwards, sharpen, pseudocolor, emboss, and reverse-contrast enhancements were applied, and radiography was re-evaluated. In addition, bitewing radiography was investigated. After data collection, data analysis was performed in SPSS using the Kruskal-Wallis test and kappa coefficient agreement at 95% confidence interval. Results: No significant difference was observed between digital panoramic and bitewing radiography in the diagnosis of interproximal caries in primary molars. The maximum coefficient of agreement was obtained in maxillary and mandibular E (ƙ=0.893) and maxillary and mandibular D (ƙ=0.874 and ƙ=0.897, respectively). Moreover, no significant differences were denoted between the enhancement tools in the diagnosis of interproximal caries (P>0.05). In general, sharpen four was found to be the most powerful tool in this regard. Conclusion: According to the results, digital panoramic imaging system was as accurate as bitewing radiography in the diagnosis of proximal dental caries. However, using enhancement tools in panoramic radiography was not helpful in the diagnosis of caries.

Introduction: Glass ionomer cement (GIC) is a restorative material used in pediatric dentistry, which attaches to dental hard tissues and has cariostatic properties due to the ability for fluoride release. The present study aimed to assess the fluoride release and uptake capacity of two GICs in the presence of various fluoride sources. Methods: This in-vitro study was conducted on 120 disks composed of two GICs (Fuji II LC, Equia Forte System), which were prepared with the exact dimensions of 5×2 millimeters. Fluoride release ability of the samples was determined every 24 hours for seven days and weekly (days 7-21) using a combination of ion selective electrodes. The samples in each group were divided into three subgroups and subjected to no fluoride treatment, fluoridated dentifrice (once a day for one minute), and MI Paste Plus (once a day for one minute). After recharging the samples for seven days, the level of fluoride release was measured on days 1-7, 14, and 21. Results: The results of one-way analysis of variance indicated that the fluoride release ability of Fuji II was higher compared to that of EQUIA Forte (P<0.001). In addition, fluoridated dentifrice could recharge both the glass ionomers more significantly than the MI Paste Plus. Conclusion: According to the results, light-cured, resin-reinforced glass ionomers could release significantly higher levels of fluoride compared to EQUIA Forte. Moreover, the fluoride rerelease was higher by the GICs when recharged with fluoridated dentifrice compared to the MI Paste Plus.
简介:玻璃离子水门合剂(GIC)是一种用于儿童牙科的修复材料，它附着在牙齿硬组织上，由于氟化物的释放能力而具有固牙特性。本研究旨在评估两种gic在不同氟源存在下的氟释放和吸收能力。方法:采用两种gic (Fuji II LC, Equia Forte System)组成的120块磁盘进行体外研究，制备尺寸为5×2 mm的磁盘。使用离子选择电极组合，每24小时测定样品的氟释放能力，持续7天和每周(7-21天)。每组的样本分为三个亚组，分别进行不加氟处理、加氟牙膏(每天一次，持续1分钟)和MI Paste Plus(每天一次，持续1分钟)。样品充电7天后，在第1-7天、第14天和第21天测量氟化物释放水平。结果:单因素方差分析结果表明，富士II的氟释放能力高于EQUIA Forte (P<0.001)。此外，与MI Paste Plus相比，含氟牙膏对这两种玻璃离子的充电效果更显著。结论:根据研究结果，光固化树脂增强玻璃离子单体释放的氟化物水平明显高于EQUIA Forte。此外，与MI Paste Plus相比，GICs在充注含氟牙膏时释放的氟化物更高。

Mutilation in the facial region may significantly affect the self-image and personality of individuals. Prosthetic rehabilitation of facial defects could increase the quality of life, thereby encouraging the patients to build up their self-confidence to return to normal social life. Acceptable cosmetic results are often obtained through facial prosthesis. Recovery after the loss of an eye requires proper adjustment to monocular vision and the improvement of appearance with an artificial eye, which is meticulously prepared to match the remaining natural eye. The present study aimed to demonstrate a technique for the fabrication of an ocular prosthesis with stock iris and custom-made sclera to provide aesthetically satisfactory results.

Introduction: There is currently significant interest in all-ceramic dental restorations. A potential non-metallic material for such restorations is an apatite-mullite glass-ceramic that could be processed to shape using different processing techniques. The aim of this study was to assess and evaluate the ability of an apatite-mullite glass-ceramic material to be processed using three routes: lost-wax casting, hot pressing and CAD-CAM milling. Methods: A batch of glass for an apatite-mullite glass-ceramic material was produced based on the formula (4.5SiO2-3Al2O3-1.5P2O5-3CaO-0.5 CaF 2). The batch was converted into glass by heating at 1050˚C/1450˚C for two hours. The final melt was quenched to obtain a glass frit. The glass was thermally treated based on the DTA data. The sequence of crystallization and their micro structural evaluation were analysed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). An anatomically correct mould of an upper right first molar was selected to trial the three different manufacturing techniques. Empress II and VITA block mark II materials were used as control materials. Results: The apatite-mullite material being evaluated can be cast and milled to shape, but the ceramic form of the material is not capable of being hot pressed. Conclusion: The materials tested show great possibility as restorative materials and could be heat treated inside and outside the investment casting material to produce a crystalline microstructure of apatite and apatite-mullite. It is possible to produce acceptable restorations using the milling technique. Hot pressing the material is not recommended due to its high liquidus temperature.
引言:目前，全陶瓷牙体修复有很大的兴趣。用于这种修复的潜在非金属材料是磷灰石-莫来石玻璃陶瓷，可以使用不同的加工技术加工成形状。本研究的目的是评估和评估磷灰石-莫来石玻璃陶瓷材料的加工能力，采用三种方法:失蜡铸造、热压和CAD-CAM铣削。方法:根据配方(4.5SiO2-3Al2O3-1.5P2O5-3CaO-0.5 CaF 2)制备一批磷灰石-莫来石玻璃陶瓷材料玻璃，在1050℃/1450℃加热2小时转化为玻璃。最后的熔体被淬火以得到玻璃熔块。根据DTA数据对玻璃进行了热处理。利用x射线衍射仪(XRD)和扫描电镜(SEM)分析了结晶顺序和微观结构。选择一个解剖正确的右上第一磨牙模具来试验三种不同的制造技术。对照材料采用皇后II型和VITA block mark II型材料。结果:所评价的磷灰石-莫来石材料可以铸造和铣削成型，但材料的陶瓷形态不能热压成型。结论:所测材料具有作为修复材料的可能性，可在熔模铸造材料内外进行热处理，形成磷灰石和磷灰石-莫来石的结晶组织。使用铣削技术可以产生可接受的修复体。由于液体温度高，不建议热压材料。

Ridge atrophy accompanied by the pneumatization of maxillary sinus in the maxillary posterior region may lead to inadequate bone height, thereby precluding implant placement. Therefore, it may be mandatory to perform a sinus membrane elevation procedure and augmentation in the bone. The present study aimed to introduce a novel modification method for sinus floor elevation using a gelatin sponge (Gelatamp, COLTENE ROEKO, India) in order for better visualization, hemostasis, and conservative maxillary sinus membrane dissection with the low risk of complications. Implant placement was performed in a case series of 28 patients with hyperpneumatized sinus or a moderately resorbed posterior maxillary alveolus. According to the findings, implant placement caused no complications in the patients. Furthermore, none of the patients experienced infections, sinusitis or graft and implant failure clinically and radiographically at the three- and six-month follow-up. Therefore, it could be concluded that gelatamp-assisted sinus lift is a simple, safe, noninvasive, and innovative technique for sinus membrane elevation. In addition, it is predictable and efficient, especially in the cases where piezoelectric surgery armamentarium is not available.

Introduction: The school-based oral health programs are an opportunity to inspire positive attitudes and proper oral health behavior in students. The purpose of this study was to compare the effects of two oral health education methods on the oral health of boarding high school students in Fariman, Iran. Methods: In this interventional study, 345 students were randomly divided into three groups, namely self-led (control), teacher-led (instructed by teachers), and peer-led (instructed by students). All students were subjected to Simplified Oral Hygiene Index (OHI-S), Gingival Index (GI), Plaque Index (PI) measurements before and three months after the intervention. The data were analyzed using the paired t-test, the Kruskal-Wallis, and the Chi-square tests. The P-value less than 0.05 was considered to be significant. Results: The results of the study showed a significant decrease regarding the scores of all three indices (P<0.001) in the peer-led group, compared to the self-led intervention. According to the paired sample t-test analyses following the intervention, there was a significant decrease in the mean OHI-S , GI, and PI in all three groups (P<0.001), peer-led group (P<0.001), and peer-led and self-led groups (P<0.001), respectively. Conclusion: Due to the significant decline in all three indices of the peer-led group compared to the other two groups, using talented students as “oral and dental health assistants” may be an effective approach for promotion of oral and dental hygiene among teenagers. However, there is aneed to conduct more research in this field of study.

The purpose of this study was to compare the effects of two oral health education methods on the oral health of boarding high school students in Fariman, Iran. Methods: In this interventional study, 345 students were randomly divided into three groups, namely self-led (control), teacher-led (instructed by teachers), and peer-led (instructed by students). All students were subjected to Simplified Oral Hygiene Index (OHI-S), Gingival Index (GI), Plaque Index (PI) measurements before and three months after the intervention. The data were analyzed using the paired t-test, the Kruskal-Wallis, and the Chi-square tests. The P-value less than 0.05 was considered to be significant. Results: The results of the study showed a significant decrease regarding the scores of all three indices (P<0.001) in the peer-led group, compared to the self-led intervention. According to the paired sample t-test analyses following the intervention, there was a significant decrease in the mean OHI-S , GI, and PI in all three groups (P<0.001), peer-led group (P<0.001), and peer-led and self-led groups (P<0.001), respectively. Conclusion: Due to the significant decline in all three indices of the peer-led group compared to the other two groups, using talented students as “oral and dental health assistants” may be an effective approach for promotion of oral and dental hygiene among teenagers. However, there is aneed to conduct more research in this field of study.","PeriodicalId":15640,"journal":{"name":"Journal of Dental Materials and Techniques","volume":"74 1","pages":"33-38"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90848276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toothbrush is a well-known tool in oral care. Effective tooth brushing can help in the management of dental caries and periodontal disease. Familiarity of children with this device is important. Dentists and their assistant need adequate information about children's oral hygiene to educate them and their parents. The aim of this review was to pinpoint the main issues of brushing teeth in children such as toothbrush design, methods of tooth brushing, and possible hazards of tooth brushing. In conclusion, tooth brushing twice daily under parent's supervision is recommended. Parents can help children and keep them safe from possible hazardous events.

Introduction: This interventional in-vitro study aimed to evaluate the antimicrobial activity of a new Nano Zinc OxideEugenol (NZOE) sealer in comparison with AH26 and Pulpdent common root canal sealers against endodontic pathogens. Methods: The antimicrobial efficacy of three sealers(NZOE, AH26 and Pulpdent) against Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), Streptococcus mutans (ATCC700610), Candida albicans (ATCC 90028), and Staphylococcus aureus (ATCC 25923) were evaluated by Direct Contact Test (DCT) at five different time intervals 0, 2, 14, 48 hours and 7 days. The results were statistically analyzed using SPSS software and Kruskal–Wallis at 5% significance level. Results: All three tested sealers had antimicrobial activity against microorganisms involved in this study. Fresh NZOE sealer eliminated all microorganisms tested, except the strain of E. faecalis colony which was reached to zero after 2 hours. However, AH26 and Pulpdent failed to completely kill all of the E. faecalis colony during the entire observation period. Also, NZOE showed a significant antimicrobial action (P<0.05) in comparison with other two sealers by effectively eliminating the Candida albicans colonies at zero time and 7 days. Conclusion: Highest antimicrobial effect of NZOE sealer was shown followed by Pulpdent sealer and AH 26 against Candida albicans and Enterococcus faecalis.
本介入性体外研究旨在评价新型纳米氧化锌丁香酚(NZOE)封管剂与AH26和Pulpdent普通根管封管剂对牙髓病原体的抗菌活性。方法:采用直接接触试验(DCT)方法，在0、2、14、48 h和7 d 5个不同时间间隔，评价3种封口剂(NZOE、AH26和Pulpdent)对粪肠球菌(ATCC 29212)、大肠杆菌(ATCC 25922)、变形链球菌(ATCC700610)、白色念珠菌(atcc90028)和金黄色葡萄球菌(ATCC 25923)的抑菌效果。采用SPSS软件和Kruskal-Wallis在5%显著性水平下对结果进行统计学分析。结果:所有三种测试封口剂对本研究涉及的微生物具有抗菌活性。新鲜的NZOE封口剂除粪肠杆菌菌落2小时后为零外，所有被测微生物均被消灭。然而，在整个观察期内，AH26和Pulpdent未能完全杀死所有粪肠球菌菌落。与其他两种封口剂相比，NZOE在0天和7天有效清除白色念珠菌菌落，具有显著的抗菌作用(P<0.05)。结论:NZOE封口剂对白色念珠菌和粪肠球菌的抑菌效果最好，其次为纸浆封口剂和AH 26。
