Test Your Dental Knowledge

Example Case

The patient is 62 years old with a cardiac history such that she is on anti-coagulants.  Her dental, and medical, history are known by her general dentist.  She develops pain in her upper back tooth (tooth #2).  That tooth had undergone a root canal procedure followed by the placement of a full crown.  The tooth had been without symptoms for several years.  She goes to the general dentist who told her that the root canal procedure should be done again told her that he can go through the crown without removing or replacing it.  He does not have her sign any consent forms and proceeds on the same day to do the procedure. He does not give her any antibiotics nor does he contact her cardiologist.  The dentist opens the canal, removes whatever was place there previously, refills the canal and closes the hole he made in the crown (to get to the canal).  Later that day she starts bleeding from her nose so much that her husband takes her to the emergency department of the nearest hospital.  That hospital does not have any dentists on staff so she is seen only by a resident physician who is in the hospital’s surgical residency program.  He diagnoses a hole in her sinus and calls in the ENT physician on staff.  He examines her and tell her that the dental procedure she just underwent perforated the sinus and that she needs surgery immediately to stop the bleeding and repair the perforation.  The resident and ENT physician never contact the general dentist before the surgery.  The surgery goes forward and the perforation is repaired and the bleeding stopped.  She recovers well from the surgery but the numbness from the surgery does not go away and today, 1 year later, she is still numb in parts of her cheek and upper lip.
