 JOURNAL OF THE AMERICAN DENTAL ASSOCIATION REPORTS:
 CAUSE OF CANKER SORES, PLAGUE OF HALF THE NATION, IS MYSTERY,
 BUT TREATMENT IS AVAILABLE
 PHOENIX, Oct. 7 /PRNewswire/ -- Their cause is a scientific


mystery, but their pain is a recurring misery for up to 125 million Americans. The October issue of the Journal of the American Dental Association (JADA) (out this week) reports that canker sores are among the most frequently encountered oral disorders, especially among upper socioeconomic classes and women.
 Canker sores are pinhead- to pea-sized ulcers found inside the mouth -- on the inner cheek, lip, gum or tongue. They are technically called recurring aphthous ulcers (RAU), from the Latin for "fire sores." They can be minor annoyances, but some RAU generate enough pain to impair eating, sleeping and speaking.
 What causes canker sores? The JADA article, "Oral Mucosal Ulcers: Diagnosis and Management," by Brad Rodu, D.D.S., and Greta Mattingly, B.S., of the University of Alabama School of Dentistry, says no single cause has been found. The immune system may be involved, but "despite intensive study, the exact role of the cellular immune system remains a mystery." AIDS patients, with clearly defective immune systems, commonly experience canker-like sores that can cover the entire palate.
 Various researchers have probed but left uncertain the causative relationship of canker sores to specific foods, trauma (such as a cheek bite), stress, hormones, heredity and chemical irritants.
 Canker sores usually start appearing between the ages of 10 and 20. But with cankers, there's solace in growing old: frequency and severity of the sores decrease with age, with lesions "rarely" occurring after age 50.
 Minor oral ulcers are the most common form, recurring without notice but typically healing in 7-10 days. Major RAU, however, are less common (involving about 10 percent of all cases) but "substantially more severe." More frequent outbreaks of larger, deeper sores can result in "the continuous presence of ulcers over many months or years."
 What do the JADA authors recommend for pain relief? "For sustained pain relief of discrete ulcerations, we utilize Zilactin, a non-prescription topical medication." Rodu and his colleague report that Zilactin forms "an adherent, durable film" on the mouth tissue "which can serve as an impermeable barrier protecting (canker sores) from trauma and irritants" up to six hours with a single application. The JADA article notes that Zilactin (or ZilaDent, which contains the topical anesthetic benzocaine) "allow patients to resume activities such as eating and speaking."
 RAU is "one of the most common and least understood oral diseases," say the researchers, but successful treatment depends upon "appropriate diagnosis and exclusion of other associated disorders." The authors especially warn of confusion of canker sores with the cold sores or fever blisters that are symptoms of the Herpes simplex virus type 1 (HSV-1). This disease is so common that it is often called "the universal infection" by doctors.
 The HSV-1 virus resides among nerve fibers deep inside the head. Stressful events seem to activate the virus; these can include fever, a cold, strong sunlight, emotional stress and anxiety. The virus generates unsightly and painful blisters on the lips and around the mouth.
 In prior articles in other medical journals, Rodu and his colleagues found that another product by Zila Pharmaceuticals, clear liquid Zilactol, kills the HSV-1 virus and speeds healing of cold sores and fever blisters.
 Zilactin, ZilaDent and Zilactol are available without prescription at drug and food stores nationwide, or from Zila Pharmaceuticals, 5227 N. 7th St., Phoenix, Ariz. 85015.
