Quality measures for dental care: A systematic review

Abstract: Objectives This systematic review aimed to (a) provide an overview of existing quality measures in the field of oral health care, and to (b) evaluate the scientific soundness and applicability of these quality measures. Methods A systematic search was conducted in three electronic databases MEDLINE (via PubMed), EMBASE (via OVID) and LILACS (via BIREME). The search was restricted to articles published between 2002 and 2018. Publications reporting on the development process or clinimetric properties of oral health care quality measures for outpatient oral health care in dental practices were included. The identified publications reporting on oral health care quality measures were critically appraised with the Appraisal of Indicators through Research and Evaluation 2.0 (AIRE 2.0) instrument to evaluate the soundness and applicability of the measures. Results The search strategy resulted in 2541 unique and potentially relevant articles. In total, 24 publications were included yielding 215 quality measures. The critical appraisal showed a large variation in the quality of the included publications (AIRE scores ranging from 38 to 78 out of 80 possible points). The majority of measures (n = 71) referred to treatment and preventive services. Comparably, few measures referred to the domain patient safety (n = 3). The development process of measures often exhibited a lack of involvement of patients and dental professionals. Few projects reported on the validity (n = 2) and reliability (n = 3) of the measures. Four projects piloted the measures for implementation in practice. Conclusions This systematic review provides an overview of the status quo with respect to existing quality measures in oral health care. Potential opportunities include the piloting and testing of quality measures and the establishment of suitable information systems that allow the provision of transparent routine feedback on the quality of oral health care.

The therapeutic potential of regulatory T lymphocytes in periodontitis: A systematic review.

Abstract: This systematic review aimed to: (a) generate a descriptive synthesis of preclinical studies assessing the therapeutic potential of regulatory T lymphocytes (Tregs) to arrest periodontitis, (b) evaluate the methodological heterogeneity of the reviewed animal studies and (c) assess the risk of bias (RoB) of the included studies. The electronic search for animal studies included the MEDLINE, EMBASE, Web of Science and LILACS databases. In addition, a manual search assessed the high-ranked scientific journals in "periodontics/immunology" and the references listed in the included studies. There were no language, year or publication status restrictions. Two independent reviewers selected and extracted the data, and Cohen's Kappa coefficient was calculated to determine the inter-examiner agreement. The Systematic Review Center for Laboratory Animal Experimentation's (SYRCLE) tool was used to assess the RoB. A total of 21 of the 425 studies obtained from the database search were included. Treg function was mainly described in Porphyromonas gingivalis-induced periodontitis (57.1%) in mice (76.2%), where Treg suppression was strongly related to disease progression and Treg induction was strongly related to immuno-inflammatory response reduction. Of those 21 studies, eight included eight animal experiments using three distinct therapeutic approaches, including: P. gingivalis-driven immunization (n = 3), retinoic acid inoculation (n = 2) and anti-inflammatory molecules in polymeric carriers (n = 3), which could modulate the Treg activity through cytokine production (interleukin-10 and transforming growth factor-β1), CC-chemokine- and CC-chemokine receptor-mediated chemoattraction (CCL22 and CCR4) or Th17-associated receptor activator of nuclear factor κB ligand (RANKL) downregulation. However, the studies with animal experiments did not specify the randomization sequences and housing conditions that were used, and therefore, 42.11% of the entries were rated as unclear RoB. Distinct therapeutic strategies involving Tregs could potentially suppress the immuno-inflammatory response and restore alveolar bone homeostasis during periodontitis. Nevertheless, important methodological variability, poor reporting of treatment effect estimates and unclear RoB suggest using caution when assessing the results of these studies.

Brazilian Articles in Top-Tier Dental Journals and Influence of International Collaboration on Citation Rates.

Abstract: This study investigated the presence of co-authorship from Brazil in articles published in top-tier dental journals and analyzed the influence of international collaboration, article type (original research or review), and funding on citation rates. Articles published between 2015 and 2017 in 38 selected journals from 14 dental subareas were screened in Scopus. Bibliographic information, citation counts, and funding details were recorded for all articles (N=15619). Collaboration with other top-10 publishing countries in dentistry was registered. Annual citations averages (ACA) were calculated. A linear regression model assessed differences in ACA between subareas. Multilevel linear regression models evaluated the influence of article type, funding, and presence of international collaboration in ACA. Brazil was a frequent co-author of articles published in the period (top 3: USA=25.5%; Brazil=13.8%; Germany=9.2%) and the country with most publications in two subareas. The subjects with the biggest share of Brazil are Operative Dentistry/Cariology, Dental Materials, and Endodontics. Brazil was second in total citations, but fifth in citation averages per article. From the total of 2155 articles co-authored by Brazil, 74.8% had no co-authorship from other top-10 publishing countries. USA (17.8%), Italy (4.2%), and UK (3.2%) were the main co-author countries, but the main collaboration country varied between subjects. Implantology and Dental Materials were the subjects with most international co-authorship. Review articles and articles with international collaboration were associated with increased citation rates, whereas the presence of study funding did not influence the citations.

Are researchers paying too much for attending dental meetings

Abstract: Dental meetings are important venues for sharing knowledge and experiences among researchers and clinicians. The costs for participating in such events, however, are high and have increased over the years. This opinion paper discusses the fairness of such a policy, with high costs for researchers presenting their findings, as well as some suggestions to reduce the economic burden of participants actively involved in presenting their research findings.
