(Content under development) The following linked questions were submitted by a practising dentist: Does crown-root (C/R) ratio matter or not with an integrated implant and, then more importantly, what do you do in your practice?

(Content under development) The following question was submitted by a practicing dentist: As I now practice in a newly “non-fluoridated” area I am looking at my recommendations for supplemental fluoride for my pediatric population.

Before prescribing fluoride supplements, a thorough clinical examination, dental ...Read More »

JCDA Editorial Consultant Dr. Alan Kilistoff of the University of Alberta provided this initial response for consideration: The immediate answer is yes, but in context it is probably not clinically significant. An article from Mazzaoui et al, demonstrates that fluoride release is about 75-90% less available after coating with a resin adhesive, but that fluoride is still available. The main purpose of the coating is to ...Read More »
