Two new critical summaries are now available from the ADA-EBD website.
First is a summary of a 2012 systematic review by Zandbergen et al that looked the systemic administration of amoxicillin and metronidazole as an adjunct to scaling and root planning (Dental Elf 25th May 2012). The review notes that there was no comparison in this review with scaling and root planning alone and that adverse events were not addressed. In our May 2012 Dental Elf blog we also highlighted 7 other similar recent reviews.
The second summarises a 2010 review by Waasdorp that considered whether the presence of infection compromised the osseointegration of implants placed immediately into an extraction site. The appraiser noted that only a small number of low quality studies involving small numbers of implants were available. While the review suggests over 90% success at one year the supporting evidence is currently weak.
