C A S E S T U DY : N E U R O PAT H I C PA I N<br />
Treating Dentist: Dr. Gerald Ross<br />
A 61-year-old male patient presented with pain and felt it was coming<br />
from the lower left molar. The tooth was extracted and the socket healed<br />
uneventfully but the pain got worse. At that point, there were no other<br />
problems with teeth in that quadrant, however the pain was worsening<br />
and the patient was taking Tylenol ® No. 3 (30 mg) approximately 4 times<br />
per day, every day. <strong>Laser</strong> irradiation was applied to the trigeminal nerve,<br />
the molar site, and the trigeminal ganglion. After 1 application, the<br />
patient said he was no longer taking Tylenol No. 3 and took only 2 Advil ®<br />
at bedtime. Three days later a second application was done to the same<br />
site, and the patient reported as pain-free and no longer needing medication.<br />
The pain-free status has lasted for three months.<br />
