Do antibiotics before invasive dental procedures prevent infections in patients who have had arthroplasties of the hip or knee?
This was a question posed by researchers at the University of Geneva Hospital, in Geneva, Switzerland.
These authors systematically reviewed the PubMed database, for articles related to the development of infection following invasive dental procedures in patients who have had arthroplasties of the hip or knee. They hand-searched the bibliographies of relevant references and did not limit their search to clinical trials. They found 24 case reports, 3 small case series, and 34 review articles; 23 papers that prospectively assessed the rate of asymptomatic bacteremia; and no controlled studies.
The authors concluded that it is possible that prophylactic antibiotics prevent infections in patients with previous arthroplasty undergoing invasive dental procedures. However, there was no reliable data on the subject.

On March 27, 2008 the ADA conducted an evidence based dentistry (EBD) workshop to teach critical summary skills. Participants learned to write critical summaries of systematic reviews. These summaries will be a key feature of a new website focusing specifically on EBD. An additional workshop will be held in June.
The ADA has created a temporary web page as they work to develop an enhanced EBD website. This new content area features a searchable directory of systematic reviews, a glossary of terms, and additional resources on evidence-based dentistry. The project is supported with a grant from the National Library of Medicine.

Tobacco smoking has been a known risk factor for periodontitis but it was uncertain whether or not cannabis use was harmful. Essential Evidence Plus reviews a recent cohort study, published in the Journal of the American Medical Association, which concluded that regular marijuana smoking increases the risk of periodontal disease and subsequent loss of teeth.
