拔牙后出血是术中及术后极其常见的并发症之一。随着当今三高（高血压、高血脂、高血糖）等各种慢性系统性疾病的高发以及发病人群的低龄化,拔牙后出血发病率逐年增加,且常导致患者生理及心理各种不良后果,尤其伴随“牙医恐惧症”渐被关注,减少甚至避免拔牙出血的方法很有研究价值。本文搜索了CNKI内,1990年-2017年的相关文献,拟用关键词“拔牙”“止血”“并发症”等,经筛选后62篇纳入整理归纳。根据近30年来有关中西医各类拔牙止血方法的机制、利弊及临床疗效的研究作综述,旨在为未来临床新的拔牙止血方法提供科学依据。     

Immediate implant placement in endodontically infected sites: an alternative treatment for compromised teeth

In certain clinical conditions when endodontic treatment is either impractical or unlikely to improve the previous results, tooth extraction and replacement with a dental implant becomes a viable alternative. Although the presence of active infection has long been considered a major contraindication to the insertion of implants immediately following tooth extraction, several articles assessing this treatment modality reported excellent and promising results. The aim of this literature review is to evaluate and discuss the clinical outcome of implants placed immediately following extraction in endodontically infected sockets. A Medline and EMBASE search was performed to identify articles published from 1966 to 2010 using the keywords "dental implants", "immediate implant", "extraction socket", "infected teeth", "infected site", "infected socket". No restrictions were placed regarding the study design. Only clinical articles with at least 6 months of follow-up were included. The available relevant literature concerning this topic was limited, and based on relatively low level of evidence study designs with limited follow-up periods. However, the data analysis of the selected articles showed that an immediate implant insertion in endodontically infected sites following tooth extraction and careful debridement of the socket, could be a predictable viable technique. Additional large scaled, well-designed studies are required in order to further assess the clinical applications of this treatment alternative.     

恒前牙外伤固定疗效国内临床试验的循证医学质量评价

目的：通过循证医学方法,评价近10年国内发表的关于使用各种固定方法治疗恒前牙外伤的临床试验质量。方法：搜索CNKI与万方数据库(2001—2011年),以“恒前牙外伤”作为主题词进行搜索,共获得245篇可能相关的文献,浏览摘要后,得到46篇关于恒前牙固定疗效的文献,对临床试验的设计进行分类评价,分别采用临床试验统一报告标准(CONSORT)和加强观察性流行病学研究报告声明(STROBE)所建立的临床试验评价标准进行质量评估。结果：46篇临床试验中,随机对照试验8篇,其余38篇均为观察性研究。绝大部分试验设计不够科学严谨,即使是随机对照试验,其随机方法、分配方式的隐藏、盲法的采用等方面并不完善,无法进行全面的方法学质量评价。结论：国内关于恒前牙外伤固定疗效临床试验的质量有待提高,需在试验设计和论文写作上加以完善。

A survey of Swiss swimming pool attendants' knowledge of first-aid treatment after lip and dental injuries

Summary: Although dental injuries are common occurrences at swimming pools, there are very few publications about them. The purpose of this study was to interview pool attendants at public swimming pools/bathing resorts in Switzerland on lip and dental injuries in 2007. The questions focussed on their knowledge of first aid, the frequency and accident site of lip and tooth trauma, as well as the storage medium for avulsed teeth. Questions were also asked about the presence of a "dental first-aid kit" and the poster on dental first aid. 606 public pools were contacted, and one pool attendant per pool was interviewed by telephone. 553 individuals participated; 53 declined to take part. The results show that in 2007, 40% of the interviewed pool attendants (n = 221) had witnessed at least one lip injury, and 36.9% (n = 204) at least one tooth trauma. At pools with slides, accidents were more frequent (p<0.001), and the waterslide was the most common accident site. The pool attendants provided satisfactory answers on their actions after lip and dental injuries. However, 68.7% could not adequately answer the questions on storage of avulsed teeth. Only 74 pool attendants had a dental first-aid kit. Of these, only 68 used the kits as the storage medium for avulsed teeth. 59 pool attendants were in possession of the poster on dental first aid. Overall, it was shown that pool attendants who had a dental first-aid kit and a dental first aid poster gave better answers on how to handle tooth trauma.     

Occurrence and Risk Factors of Dental Root Perforations: A Systematic Review

BackgroundIatrogenic root perforations are an unfortunate accident that can occur during dental treatment and can lead to peri-radicular damage, poor treatment outcome and extraction of the tooth. The aim of this review was to analyse the occurrence and risk factors for root perforation.MethodsA systematic search of the literature was conducted in CINAHL, Cochrane, EMBASE, Medline and SCOPUS in May 2019. Additional literature was identified through a hand search. Clinical studies enrolling adults with permanent dentition were included. Single case studies and case reports were excluded. Duplicate articles were removed, titles and abstracts were screened and studies were selected according to the inclusion criteria. Data were collected and reported in accordance with PRISMA guidelines. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Tools.ResultsA total of 916 articles were screened, from which 47 full-text articles were analysed and 22 articles were finally included in the study. The data were analysed qualitatively because meta-analysis could not be conducted owing to lack of heterogeneity among the studies. Most of the articles were retrospective cross-sectional studies on root canal treatments performed by undergraduate students. The occurrence of perforation ranged from 0.6% to 17.6%. Risk factors for perforation included experience of the practitioner, tooth type, and tooth morphology. The risk of bias in most of the studies included was assessed as low.ConclusionsThis systematic review suggests a need for additional studies on the risk factors associated with iatrogenic root perforation as the current literature is insufficient. Educational efforts in dental schools should address the issue of perforations and provide more clinical experience prior to graduation in order to improve the clinical skills of graduates.     

More women in Europe and Australia have dental agenesis than their counterparts in North America

DATA SOURCES: Medline and Embase were searched, using the following keywords: "hypodontia", "oligodontia", "anodontia", "agenesis", and "prevalence or incidence". Reference lists from retrieved articles were also examined. STUDY SELECTION: For inclusion, an article had to satisfy the following criteria: presence of an English abstract; the sample was representative for the underlying general population; the diagnosis of dental agenesis was based on a radiographic examination; the report presented information on the ethnic background; and the report presented prevalence of agenesis except third molars. DATA EXTRACTION AND SYNTHESIS: Data from Caucasian populations in North America, Australia and Europe were included in a meta-analysis. For the prevalence in African-American, Chinese and Arab groups, only indications could be reported because of a limited number of studies. Multiple-regression analysis was applied to evaluate the influence of chronological age, sample size, continent and year of publication. Statistical significance was established at P<0.05. The prevalence of agenesis per tooth type, affected patients and number of missing teeth per patient was calculated as far as reported in the papers. For the comparison of the prevalence for males and females, the relative risk (RR) was calculated. RESULTS: The search identified 141 articles, of which 31 met the inclusion criteria. Agenesis differs by continent and gender: the prevalence for both sexes was higher in Europe (males 4.6%; females 6.3%) and Australia (males 5.5%; females 7.6%) than for North-American Caucasians (males 3.2%; females 4.6%). In addition, the prevalence of dental agenesis in females was significantly higher than in males for all three continents, with an RR of 1.37 (95% CI, 1.28-1.45). The mandibular second premolar was the most affected tooth, followed by the maxillary lateral incisor and the maxillary second premolar. Unilateral occurrence of dental agenesis is more common than bilateral occurrence. Bilateral agenesis of maxillary lateral incisors is more common, however, than unilateral agenesis. In most patients, dental agenesis involved only one (48%) or two teeth (35%). CONCLUSIONS: The prevalence of dental agenesis in Europe and Australia is higher than in North America. The overall prevalence of agenesis in the maxilla is comparable with that in the mandible, but a marked difference was found between both jaws regarding tooth type. Absence of one or two permanent teeth is found in the majority of the subjects with dental agenesis.

Trend in dental research output in Iran over a period of 20 years (1990–2009)

Introduction: The number of scientific papers is a conventional metric for the measurement of a country’s research performance in a particular area. Objective: To evaluate the trend in Iranian publications of dental research results in peer-reviewed international scientific journals over the period 1999–2009, using national and international databases, and to compare the results with other countries. Methods: The search process was performed by two independent persons in PubMed and Iranian Medline (IranMedex). Data extraction included the year of publication, total number of dental papers in each year, total number of Iranian dental papers in each year and number of papers with a high level of evidence; these were compared with those in other Asian countries. Results: The total number of dental articles indexed in PubMed during the studied period was 207,689, with 671 being written by researchers who stated their affiliation as Iran. Although the proportion of Iranian dental articles to all published dental articles was 0.01% in 1990, this increased to 1.4% in 2009. Of all clinical trials indexed in PubMed from 1990 to 2009, only 0.62% had an author from Iran. The collaboration rate of authors ranged between 1 and 10. Turkey and Iran had a larger number of dental research publications compared with other Asian countries assessed in this study. Conclusion: During the last two decades, there has been a considerable increase in the number of dental papers by Iranian researchers indexed in the PubMed database.Key words: Dental, research, Iran
