Can upper jaw surgery lead to root canals years later?

I was 17 (19 years ago) when I had maxillofacial surgery to correct an open bite issue.  My wisdom teeth were extracted at the same time and my jaws wired shut for 6 weeks until everything healed.
I have been very happy with the results but in the last 4 years I have had 4 root canals in the upper front incisors and canines.  

Is there any documented correlation between upper jaw surgery and the rate of incidence of root canals in the affected jaw?  I am now worried that the rest of my upper front teeth, and possibly the molars, will eventually require root canals.  I have had no trauma to my mouth other than the surgery almost 20 years ago and a filling in 2 of the teeth prior to the root canal procedure.  
Thank you for your time.

Orthognathic surgery may jeopardize blood supply of teeth, which may result in pulpal necrosis.

Thanks for your response.  I hadn't considered that possibility but I will discuss it with my dentist.
