1Can eradication rate of gastric Helicobacter pylori be improved by killing oral Helicobacter pylori ?显示文摘AIM:To evaluate the influence of oral Helicobacter pylori(H.pylori)on the success of eradication therapy against gastric H.pylori.METHODS:A total of 391 patients with dyspepsia were examined for H.pylori using the saliva H.pylori antigen test(HPS),13C-urea breath test(UBT),gastroscopy,and gastric mucosal histopathological detection.Another 40 volunteers without discomfort were subjected to HPS and13C-UBT,and served as the control group.The 233 patients who were13C-UBT+were enrolled in this study and divided into 4 groups.Patients who were HPS-and13C-UBT+(n=53)received triple therapy alone.Those who were both HPS+and13CUBT+(n=180)were randomly divided into 3 groups:(1)the O+G+t group which received triple therapy alone(n=53);(2)the O+G+tm group which received both triple therapy and mouthrinse treatment(n=65);and(3)the O+G+tmp group which received triple therapy,mouthrinse,and periodontal treatment(n=62).The HPS and13C-UBT were continued for 4 wk after completion of treatment,and the eradication rate of gastric H.pylori and the prevalence of oral H.pylori in the 4 groups were then compared.RESULTS:The eradication rates of gastric H.pylori in the O-G+t group,the O+G+tm group,and the O+G+tmp group were 93.3%,90.0%,and 94.7%respectively;all of these rates were higher than that of the O+G+t group(78.4%)[O-G+t group vs O+G+t group(P=0.039);O+G+tm group vs O+G+t group(P=0.092);O+G+tmp group vs O+G+t group(P=0.012);O+G+tm group vs O-G+t group(P=0.546);O+G+tmp group vs O-G+t group(P=0.765);O+G+tm group vs O+G+tmp group(P=0.924)].The eradication of gastric H.pylori was significantly improved using the combination of triple therapy,mouthrinse,and periodontal treatment.The eradication rates of gastric H.pylori in the peptic ulcer group,chronic atrophic gastritis group and control group were higher than in the duodenitis group and the superficial gastritis group.The prevalence rates of oral H.pylori in the O-G+t group,O+G+t group,O+G+tm group and O+G+tmp group following treatment were 0%,76.5%,53.3%,and 50.9%,respectively[O-G+t group vs O+G+t group(P<0.0001);O+G+tm group vs O+G+t group(P=0.011);O+G+tmp group vs O+G+t group(P=0.006);O+G+tm group vs O-G+t group(P<0.0001);O+G+tmp group vs O-G+t group(P<0.0001);O+G+tm group vs the O+G+tmp group(P=0.790)].Both mouthrinse and periodontal treatment significantly reduced the prevalence of oral H.pylori.CONCLUSION:Mouthrinse treatment alone or combined with periodontal treatment can,to some extent,reduce the prevalence of oral H.pylori and improve the eradication rate of gastric H.pylori.Han-Yi Song Yan Li 2013World Journal of Gastroenterology2013,19,39:29
2Transmission routes of 2019-nCoV and controlsin dental practice显示文摘A novel β-coronavirus(2019-nCoV) caused severe and even fatal pneumonia explored in a seafood market of Wuhan city, Hubei province, China, and rapidly spread to other provinces of China and other countries. The 2019-nCoV was different from SARS-Co V,but shared the same host receptor the human angiotensin-converting enzyme 2(ACE2). The natural host of 2019-nCoV may be the bat Rhinolophus affinis as 2019-nCoV showed 96.2% of whole-genome identity to Bat Co V Ra TG13. The person-to-person transmission routes of 2019-nCoV included direct transmission, such as cough, sneeze, droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal, and eye mucous membranes. 2019-nCoV can also be transmitted through the saliva, and the fecal–oral routes may also be a potential person-to-person transmission route. The participants in dental practice expose to tremendous risk of 2019-nCoV infection due to the face-to-face communication and the exposure to saliva, blood, and other body fluids, and the handling of sharp instruments. Dental professionals play great roles in preventing the transmission of2019-nCoV. Here we recommend the infection control measures during dental practice to block the person-to-person transmission routes in dental clinics and hospitals.Xian Peng Xin Xu Yuqing Li Lei Cheng Xuedong Zhou Biao Ren 2020International Journal of Oral Science2020,12,1:29
3颞下颌关节紊乱病的RDC/TMD标准化诊断显示文摘1991年在美国国立牙科研究院(National Institute of Dental Research)资助下,制定了TMD研究用诊断标准(Research Diagnostic Criteria for Temporomandibular Disorders,简称RDC/TMD),并从全美召集一部分TMD临床和流行病学研究人员对此标准进行讨论,达成共识。傅开元 2009中国口腔医学继续教育杂志2009,,2:27
4Immunomodulatory properties of dental tissue-derived mesenchymal stem cells: Implication in disease and tissue regeneration显示文摘Mesenchymal stem cells(MSCs)are considered as an attractive tool for tissue regeneration and possess a strong immunomodulatory ability.Dental tissuederived MSCs can be isolated from different sources,such as the dental pulp,periodontal ligament,deciduous teeth,apical papilla,dental follicles and gingiva.According to numerous in vitro studies,the effect of dental MSCs on immune cells might depend on several factors,such as the experimental setting,MSC tissue source and type of immune cell preparation.Most studies have shown that the immunomodulatory activity of dental MSCs is strongly upregulated by activated immune cells.MSCs exert mostly immunosuppressive effects,leading to the dampening of immune cell activation.Thus,the reciprocal interaction between dental MSCs and immune cells represents an elegant mechanism that potentially contributes to tissue homeostasis and inflammatory disease progression.Although the immunomodulatory potential of dental MSCs has been extensively investigated in vitro,its role in vivo remains obscure.A few studies have reported that the MSCs isolated from inflamed dental tissues have a compromised immunomodulatory ability.Moreover,the expression of some immunomodulatory proteins is enhanced in periodontal disease and even shows some correlation with disease severity.MSC-based immunomodulation may play an essential role in the regeneration of different dental tissues.Therefore,immunomodulation-based strategies may be a very promising tool in regenerative dentistry.Oleh Andrukhov Christian Behm Alice Blufstein Xiaohui Rausch-Fan 2019World Journal of Stem Cells2019,11,9:21
5Human dental pulp stem cells: Applications in future regenerative medicine显示文摘Stem cells are pluripotent cells, having a property of differentiating into various types of cells of human body. Several studies have developed mesenchymal stem cells(MSCs) from various human tissues,peripheral blood and body fluids. These cells are then characterized by cellular and molecular markers to understand their specific phenotypes. Dental pulp stem cells(DPSCs) are having a MSCs phenotype and they are differentiated into neuron, cardiomyocytes, chondrocytes, osteoblasts, liver cells and β cells of islet of pancreas. Thus, DPSCs have shown great potentiality to use in regenerative medicine for treatment of various human diseases including dental related problems. These cells can also be developed into induced pluripotent stem cells by incorporation of pluripotency markers and use for regenerative therapies of various diseases. The DPSCs are derived from various dental tissues such as human exfoliated deciduous teeth, apical papilla, periodontal ligament and dental follicle tissue. This review will overview the information about isolation, cellular and molecular characterization and differentiation of DPSCs into various types of human cells and thus these cells have important applications in regenerative therapies for various diseases. This review will be most useful for postgraduate dental students as well as scientists working in the field of oral pathology and oral medicine.Pravin D Potdar Yogita D Jethmalani 2015World Journal of Stem Cells2015,7,5:18
6Role of dental plaque,saliva and periodontal disease in Helicobacter pylori infection显示文摘Helicobacter pylori(H.pylori)infection is one of the most common bacterial infections in humans.Although H.pylori may be detected in the stomach of approximately half of the world’s population,the mechanisms of transmission of the microorganism from individual to individual are not yet clear.Transmission of H.pylori could occur through iatrogenic,fecal-oral,and oral-oral routes,and through food and water.The microorganism may be transmitted orally and has been detected in dental plaque and saliva.However,the role of the oral cavity in the transmission and recurrence of H.pylori infection has been the subject of debate.A large number of studies investigating the role of oral hygiene and periodontal disease in H.pylori infection have varied significantly in terms of their methodology and sample population,resulting in a wide variation in the reported results.Nevertheless,recent studies have not only shown that the microorganism can be detected fairly consistently from the oral cavity but also demonstrated that the chances of recurrence of H.pylori infection is more likely among patients who harbor the organism in the oral cavity.Furthermore,initial results from clinical trials have shown that H.pylori-positive dyspeptic patients may benefit from periodontal therapy.This paper attempts to review the current body of evidence regarding the role of dental plaque,saliva,and periodontal disease in H.pylori infection.Pradeep S Anand Kavitha P Kamath Sukumaran Anil 2014World Journal of Gastroenterology2014,20,19:15

8计算机导航下颌无牙颌不翻瓣种植手术和即刻负重显示文摘当今,尽量减少种植手术中的创伤已经成为了一条金标准,于是计算机导航手术技术开始逐渐兴起。尽管不翻瓣的种植手术有很多临床上的优势,但是由于不是在直视下操作,不翻瓣手术仅局限于一些简单的没有皮质骨板穿通危险的病例。本文结合下颌无牙颌病例,阐述了在计算机导航下采用的不翻瓣种植手术的治疗方案。同时介绍了图像引导种植系统(IGI,DenX Advanced Dental System)。IGI系统可以实时地显示钻针的图像,使得整个不翻瓣种植手术的过程都在监控之下。有术中准确的导航系统的保证,可以精确的实施术前制定的治疗计划,这对于牙弓缺乏参照标志的无牙颌来讲尤其具有价值。根据术前数字化治疗计划.种植体植入的位置可以十分精确,因此可以在术前制作固定的临时修复体并进行即刻负重。这种全新的手术方法使得在完全监控下行不翻瓣种植手术成为了可能,同时减小了种植修复的难度。Nardy Casap Eyal Tarazi Alon Wexler Uri Sonnenfeld Joshua Lustmann 朱一博(译) 林野(校) 2005中国口腔医学继续教育杂志2005,8,4:12
9Starch grains from dental calculus reveal ancient plant foodstuffs at Chenqimogou site, Gansu Province显示文摘Chenqimogou site, located at the south bank of Tao River, is comprised of a large group of graves dated to ~4000 a BP. For its large scale, unique mortuary system, and abundant of typical artifacts, the site was named one of 'Top Ten Archaeological Discoveries of 2008 in China'. Many intact human skeletons have been excavated from the graves. Three teeth from two adult skeletons excavated from graves M187 and M194 were examined. Forty-eight starch grains were retrieved from dental calculus of three teeth. Six of those starch grains could not be identified because of damage. The others were classified into seven groups. Most of them were from wheat (Triticum aestivum) and/or barley (Hordeum vulgare). Remains possibly from foxtail millet (Setaria italica), buckwheat (Fagopyrum esculentum), gingkgo (Ginkgo biloba), acorn (Quercus spp.), bean, roots or tubers were identified. Ancient starch grains from dental calculus indicate that human foodstuffs primarily sourced from wheat, buckwheat, and foxtail millet. Acorn, beans, tubers or roots were supplements. A variety of starch grains retrieved from dental calculus revealed that diverse crops were cultivated in the Chenqimogou site 4000 years ago, and both dry-land farming and gathering were engaged.LI MingQi YANG XiaoYan WANG Hui WANG Qiang JIA Xin GE QuanSheng 2010Science China Earth Sciences2010,53,5:11
10Neural crest derived stem cells from dental pulp and tooth-associated stem cells for peripheral nerve regeneration显示文摘The peripheral nerve injuries,representing some of the most common types of traumatic lesions affecting the nervous system,are highly invalidating for the patients besides being a huge social burden.Although peripheral nervous system owns a higher regenerative capacity than does central nervous system,mostly depending on Schwann cells intervention in injury repair,several factors determine the extent of functional outcome after healing.Based on the injury type,different therapeutic approaches have been investigated so far.Nerve grafting and Schwann cell transplantation have represented the gold standard treatment for peripheral nerve injuries,however these approaches own limitations,such as scarce donor nerve availability and donor site morbidity.Cell based therapies might provide a suitable tool for peripheral nerve regeneration,in fact,the ability of different stem cell types to differentiate towards Schwann cells in combination with the use of different scaffolds have been widely investigated in animal models of peripheral nerve injuries in the last decade.Dental pulp is a promising cell source for regenerative medicine,because of the ease of isolation procedures,stem cell proliferation and multipotency abilities,which are due to the embryological origin from neural crest.In this article we review the literature concerning the application of tooth derived stem cell populations combined with different conduits to peripheral nerve injuries animal models,highlighting their regenerative contribution exerted through either glial differentiation and neuroprotective/neurotrophic effects on the host tissue.Alessandra Pisciotta Laura Bertoni Antonio Vallarola Giulia Bertani Daniela Mecugni Gianluca Carnevale 2020Neural Regeneration Research2020,15,3:10
11Effects of clinical dental implant abutment materials and their surface characteristics on initial bacterial adhesion显示文摘Initial bacterial adhesion on dental implant abutment is related to its surface chemical composition and physical characteristics.Selection of appropriate abutment materials resistant to bacterial adhesion is important for dental implant maintenance.The aim of present study was to evaluate the effect of different properties of abutment materials on initial bacterial adhesion in vitro.Polished zirconia(PZ group), polished titanium(PT group) and ground titanium(GT group) samples were prepared to simulate clinical dental implant abutments.Chemical compositions, morphology, roughness, hydrophilicity and surface free energy of materials were analyzed.Oral commensal bacterium Streptococcus mitis was used to evaluate initial bacterial adhesion via turbidity test and colony-forming unit counting.The results showed that GT group presented the highest roughness, hydrophilicity and surface free energy.After 6-h incubation, GT group showed the significantly highest adhered bacteria counts;while non-significant difference existed between PT and PZ groups.Within the clinically applicable range used in present study, the surface physical characteristics, instead of surface chemical composition, of dental abutment material have the pronounced influence on initial 6-h bacterial adhesion.Yu-Shan Huang Her-Hsiung Huang 2019Rare Metals2019,38,6:7
12现行口腔医学学制与学位教育存在问题的困惑与思考显示文摘我国的高等口腔医学教育始于1917年华西协合大学牙学院,设立之初为7年制教育,授予牙科博士学位(doctor of dental surgery,DOS)。1950年后由国家统一确定学制,20世纪50年代以5、4、3年学制为主;60年代开始设立5年制;70年代主要学制为3年;1977年恢复高考后,口腔医学学制重新确定为5年;80年代初在5年制的基础上开设了6年制。郑家伟 张志愿 邱蔚六 2009中华口腔医学杂志2009,44,3:7
13Tooth-derived stem cells: Update and perspectives显示文摘Tissue engineering is an emerging field of science that focuses on creating suitable conditions for the regeneration of tissues. The basic components for tissue engineering involve an interactive triad of scaffolds, signaling molecules, and cells. In this context,stem cells(SCs) present the characteristics of selfrenewal and differentiation capacity, which make them promising candidates for tissue engineering. Although they present some common markers, such as cluster of differentiation(CD)105, CD146 and STRO-1, SCs derived from various tissues have different patterns in relation to proliferation, clonogenicity, and differentiation abilities in vitro and in vivo. Tooth-derived tissues have been proposed as an accessible source to obtain SCs with limited morbidity, and various tooth-derived SCs(TDSCs) have been isolated and characterized, such as dental pulp SCs, SCs from human exfoliated deciduous teeth, periodontal ligament SCs, dental follicle progenitor cells, SCs from apical papilla, and periodontal ligament of deciduous teeth SCs. However, heterogeneity among these populations has been observed, and the best method to select the most appropriate TDSCs for regeneration approaches has not yet been established. The objective of this review is to outline the current knowledge concerning the various types of TDSCs, and discuss the perspectives for their use in regenerative approaches.Miki Taketomi Saito Karina Gonzales Silvério Márcio Zaffalon Casati Enilson Antonio Sallum Francisco Humberto Nociti Jr 2015World Journal of Stem Cells2015,7,2:6

15An in vitro evaluation of novel NHA/zircon plasma coating on 316L stainless steel dental implant显示文摘The surface characteristics of an implant that influence the speed and strength of osseointegration include crystal structure and bioactivity. The aim of this study was to evaluate the bioactivity of a novel natural hydroxyapatite/zircon(NHA/zircon) nanobiocomposite coating on 316L stainless steel(SS) dental implants soaking in simulated body fluid. A novel NHA/zircon nanobiocomposite was fabricated with 0(control),5, 10, and 15 wt% of zircon in NHA using ball mill for 1 h. The composite mixture was coated on SS implants using a plasma spray method.Scanning electron microscopy(SEM) was used to evaluate surface morphology, and X-ray diffraction(XRD) was used to analyze phase composition and crystallinity(Xc). Further, calcium ion release was measured to evaluate the coated nanobiocomposite samples. The prepared NHA/zircon coating had a nanoscale morphological structure with a mean crystallite size of 30–40 nm in diameter and a bone-like composition,which is similar to that of the biological apatite of a bone. For the prepared NHA powder, high bioactivity was observed owing to the formation of apatite crystals on its surface. Both minimum crystallinity(Xc=41.1%) and maximum bioactivity occurred in the sample containing 10 wt% of zircon because of minimum Xcand maximum biodegradation of the coating sample.Ebrahim Karamian Mahmood Reza Kalantar Motamedi Amirsalar Khandan Parisa Soltani Sahel Maghsoudi 2014Progress in Natural Science:Materials International2014,24,2:6
16Novel Ag nanocrystals based dental resin composites with enhanced mechanical and antibacterial properties显示文摘The aim of this work was to investigate the effect of trace addition of oleic acid coated Ag nanocrystals(Ag NCs) on mechanical and antibacterial properties of dental resin composites.Composites(70 wt%of silica loading) with 25 ppm,50 ppm,75 ppm and 100 ppm(wt) Ag NCs were prepared and the composite without Ag NCs served as a control.The experimental results showed that the addition of Ag NCs significantly improved the strength and modulus of the resin composite without compromising the shade.For the composite with 50 ppm Ag NCs,fiexural strength(140.3 MPa),modulus(13.2 GPa)and compressive strength(347.2 MPa) were increased by 4.1%,22.2%,13.3%,respectively,compared with the control.The antibacterial test demonstrated that trace Ag NCs provided the resin composites with an antibacterial effect.Such strong and antibacterial dental resin composites might be advantageous to prevent secondary caries and be potential for future clinical applications.Fengwei Liu Ruili Wang Yuyuan Shi Xiaoze Jiang Bin Sun Meifang Zhu 2013Progress in Natural Science:Materials International2013,23,6:5
17Polymeric vs hydroxyapatite-based scaffolds on dental pulp stem cell proliferation and differentiation显示文摘AIM: To evaluate adhesion, proliferation and differentiation of human dental pulp stem cells(h DPSCs) on four commercially available scaffold biomaterials. METHODS: hD PSCs were isolated from human dental pulp tissues of extracted wisdom teeth and established in stem cell growth medium. h DPSCs at passage 3-5 were seeded on four commercially available scaffold biomaterials, SureO ss(Allograft), Cerabone(Xenograft), PLLA(Synthetic), and OSTEON Ⅱ Collagen(Composite), for 7 and 14 d in osteogenic medium. Cell adhesion and morphology to the scaffolds were evaluated by scanning electron microscopy(SEM). Cell proliferation and differentiation into osteogenic lineage were evaluated using DNA counting and alkaline phosphatase(ALP) activity assay, respectively. RESULTS: All scaffold biomaterials except Sure Oss(Allograft) supported h DPSC adhesion, proliferation and differentiation. hD PSCs seeded on PLLA(Synthetic) scaffold showed the highest cell proliferation and attachment as indicated with both SEM and DNA counting assay. Evaluating the osteogenic differentiation capability of hD PSCs on different scaffold biomaterials with ALP activity assay showed high level of ALP activity on cells cultured on PLLA(Synthetic) and OSTEON ⅡCollagen(Composite) scaffolds. SEM micrographs also showed that in the presence of Cerabone(Xenograft) and OSTEON Ⅱ Collagen(Composite) scaffolds, the h DPSCs demonstrated the fibroblastic phenotype with several cytoplasmic extension, while the cells on PLLA scaffold showed the osteoblastic-like morphology, round-like shape. CONCLUSION: PLLA scaffold supports adhesion, proliferation and osteogenic differentiation of hD PSCs. Hence, it may be useful in combination with hD PSCs for cell-based reconstructive therapy.Arash Khojasteh Saeed Reza Motamedian Maryam Rezai Rad Mehrnoosh Hasan Shahriari Nasser Nadjmi 2015World Journal of Stem Cells2015,7,10:5
18刍议我国“口腔医院”的名称英译显示文摘由于口腔医学体系不同,为区别欧美牙科体系,我国的口腔医院普遍译为stomatological hospital。许多英美主流词典对stomatology及其派生词均未收录,普通英语读者对这一词汇不熟悉,导致其对目前我国口腔医院英译认知度不高。在分析我国口腔医院与美国牙科诊所异同及stomatology与dentistry在词典释义重合度的基础上,文章提出我国口腔医院可灵活处理成dental and oral medical hospital等多种形式。李海清 刘华文 2014上海翻译2014,,2:5
19Microscopic removal of type Ⅲ dens invaginatus and preparation of apical barrier with mineral trioxide aggregate in a maxillary lateral incisor:A case report and review of literature显示文摘BACKGROUND Invaginated teeth pose greater challenges in clinical management because of their complex configuration.With advancements in equipment and materials,such as the dental operation microscope,cone-beam computed tomography and mineral trioxide aggregate,the preservation rate of type Ⅲ dens invaginatus could be greatly increased.CASE SUMMARY This case report presented a 31-year-old woman with complaints of spontaneous swelling and pain in the right maxillary lateral tooth.With the aid of cone-beam computed tomography,type Ⅲ dens invaginatus with apical periodontitis was diagnosed and confirmed.Three-visit endodontic treatment was performed.In the first visit,the invagination was carefully removed under the dental operation microscope,and chemomechanical preparation was done.In the second visit,mineral trioxide aggregate apical barrier surgery was performed in this tooth.In the third visit,the canal was finally obturated with thermoplastic gutta-percha to recover the crown morphology.A 26-mo follow-up revealed a satisfied outcome both in the radiographic and oral examinations.CONCLUSION In this case,removal of the entire abnormal structure provided great convenience for the follow-up treatment.When confronted with the same clinical case in the future,we can take a similar approach to address it.Jie Liu Yue-Rong Zhang Fu-Yu Zhang Guang-Dong Zhang Hai Xu 2020World Journal of Clinical Cases2020,8,6:4
20Sudden sensorineural hearing loss(SSHL) following a local anesthetic dental procedure显示文摘Acute sensorineural hearing loss is an uncommon phenomenon in dentistry.We describe the case of a 79-year-old male who presented with acute sensorineural hearing loss occurring 2 days after a tooth extraction procedure under local anesthesia.Possible mechanisms are discussed.He was treated with vasodilators(Ginaton and Alprostadil Injection)and Mecobalamin injection with benefit.High dose oral steroids(1 mg/kg)and low molecular weight dextran were used.Yi Wang Jun-Kai Cao Hui-Xin Yang Jin Feng Qi-you Zhou Fei Ji 2019Journal of Otology2019,14,2:4
