They are generally painful, except for squamous cell carcinoma, which may be asymptomatic, when it presents as an ulcer. Traumatic ulcers are usually the result of physical injury eg, accidental biting during mastication, contact with sharp or broken cusps of teeth, and sharp food , and less often, thermal or chemical burn eg, chemicals used during dental or surgical procedures, aspirin, alcohol, peroxide, and other acidic substances. Rarely, electrical injury can occur, especially in very young children who accidentally chew on an Forgot Password?

Medications that are effective for specific conditions but were limited in use due to adverse gastrointestinal effects, high first pass metabolism, and poor bioavailability are now being evaluated for transdermal administration. Controlled and sustained drug delivery through nanoparticle design and by use of the skin as a drug reservoir is revolutionizing the way we look at transdermal drug administration.
We can now truly say we have skin in the drug game. Continuing advances in skin penetration enhancement are allowing new and old drugs to be administered transdermally, providing prolonged therapeutic effects and improved patient safety.
