This is because the key words used are limited to MeSH vocabulary, as opposed to previous bibliometric studies in which, furthermore, multiple free-text searches are used because the specialty being studied in MeSH is not well represented. MEDLINE, being a bibliographic database, normally lags behind the profession in adopting new language. Therefore, the searches, by not being entirely language-inclusive, may have excluded relevant articles. In addition, in the design of a search strategy, there are two options: (1) to make an exhaustive search, which indicates a search strategy that retrieves the largest number of relevant articles but also includes some irrelevant ones or (2) to make a specific search, a selective search strategy, which identifies a small number of the most relevant articles and excludes most irrelevant articles but,unfortunately, also excludes some relevant articles. In the present study, the mixed strategy, both thematic and institutional, ensures the specificity of the searches, while the high numbers of descriptors used, unusual in this type of work,are meant to reach a high percentage of retrieval. Nevertheless, we believe that the possible influence of some of these limitations (if there are any) would remain constant overtime and their repercussion in the trend and distribution. Sir, the dental research community has received continuous support by taxpayers in the expectation that results may lead to significant improvements in the public's oral health.1 Arguably, this has not happened and the quality and sustainability of dental research does not match that in other health disciplines. The body of literature on dentistry is dominated by observational studies, short-term trials, reviews or technical reports. Reasons cited for the absence of high-quality research are often related to funding issues, lack of research activity of dental faculty, and separations of the full-time dental faculty.The National Health and Medical Research Council (NHMRC) is the principal funding body for health and medical research in Australia, with an annual budget of AU$700 million. Despite the burdens of poor oral health and increasing dental care spending (AU$9 billion in 2013), oral health is not listed as a National Health Priority Area for NHMRC research funding. Between 2011 and 2015, cancer, mental health, diabetes and cardiovascular disease groups received the greatest proportion of such funding.Although clinical dentists are the principal leaders of the dental team, their contributions to dental research and peer-review publications are relatively limited.2 In Australia 85% of dentists practise in the private sector resulting in less time to focus on pursuing scholarly activities or national policymaking. Dental faculty shortages have been reported in various countries with income gaps between academic and private posts and the additional time for preparation for academic careers cited as reasons.2 Other factors are a risk of losing the job, reduced potential to achieve tenure or promotion as many dental schools demand peer-reviewed publications and a consistent record of funding.2Members of the dental team, in particular, dentists, have a responsibility to advocate for funding equity in dentistry and contribute to closing the gap in oral health. Further evidence-based research addressing oral health disparities and burden of oral diseases is needed as this could guide or encourage national funding agencies to prioritise dental research in their funding plans. Abstract: Dental therapists are members of the dental team in many countries, where they perform a limited number of irreversible restorative procedures. In the United States, they practice only in Alaska and Minnesota, though other states are considering adding them in an effort to improve access to care. While critics of this workforce model cite concern for patient safety, proponents argue that dental therapists provide treatment that is as technically competent as that provided by dentists. Though nearly 2 dozen studies from industrialized countries address this subject, this article systematically reviews all 23 of them. Of these reports, all but 2 conclude that dental therapists perform at an acceptable level. Every study that directly compared the work of dental therapists with that of dentists found that they performed at least as well. Regardless of whether dental therapists
