What are the advantages and disadvantages of self-adhesive resin cements for crown & bridge cementation?
This question was submitted to us by a practising dentist: What are the pros and cons of self-adhesive resin cements (i.e.: RelyX, Unicem 2) and resin modified glass ionomers (i.e.: FujiCEM 2) in crown and bridge cementation? Are they equally reliable? Dr. Omar El-Mowafy, Head of Restorative Dentistry at the University of Toronto provided this initial response: Advantages of self-adhesive resin cements 1. Eliminate the need for etching tooth structure or application of primer/bonding agent; and as a result, dramatically reduce the potential for post-operative sensitivity . 2. Dual-cured: excess cement can be briefly light-cured for ease of use. When used with a ...Read More »

The following question was submitted by a practicing dentist: What may happen with patients who have a prolonged QT due to their SSRI or Prozac medication when they are administered a local anesthetics-containing epinephrine? The following response is provided by Dr. Joonyoung Ji, resident in the Department of Dental Anesthesia at the University of Toronto Main take-away message Epinephrine, stress, and using more than one psychotropic increases the QT interval. The majority of patients have significant medical co-morbidities in reported cases of arrhythmia associated with psychotropics. Therefore, limiting the use of epinephrine to under 40 mcg or no more than 2 cartridges of ...Read More »
This short consult is presented by Dr. Eric Stoopler, DMD; Dr. Arthur Kuperstein, DDS; and Dr. Thomas Sollecito, DMD Peer-reviewed content that appeared in the JCDA OASIS “point of care” searchable database at www.jcdaoasis.ca and in the sixth edition of the print JCDA.

Treatment of primary HSV infections ...Read More »
How can I promote esthetic papilla formation between adjacent implant-supported restorations on upper anterior teeth?
The following verbatim question was submitted by a practising dentist: My patient had implants to replace 11 and 21. I have placed contoured healing abutments and temporary crowns with the contact 4-5 mm above the bone (2 mm gingiva and 2 mm space). These have been in place 4 months and although the papilla has filled in between the laterals, the tissues are still flat between the 11 and 21 despite the fact that a periodontist placed the implants doing a graft to “bulk up” the tissue. The patient is not overly concerned; however, you can see the area when he smiles, so ...Read More »
