Slide 1

Orofacial Pain

Slide 2

  • A relatively common symptom.

  • Sources of orofacial pain include caries, periodontitis, neuropathic, and musculoskeletal conditions.

  • Symptoms of pain may represent different phases of acute or chronic conditions.

  • Based on NHIS data from 1989, survey participants representing 39 million adults reported experiencing at least one of five orofacial pain symptoms in the past 6 months:

    • tooth pain,

    • mouth sores,

    • jaw joint pain,

    • facial pain,

    • burning mouth

      (Lipton et al., 1993).

Slide 3

  • Orofacial pain is often divided into two categories.chronic and acute.

  • The National Center for Health Statistics generally uses a cut off point of 3 months to distinguish between acute and chronic pain.

  • Currently, there are no national data on orofacial pain for children.

  • Data sources other than the 1989 NHIS include studies on a population of elderly adults (65+) living in 10 northern Florida counties (Riley et al., 1998); studies of adults 45 and older, also located in northern Florida (Gilbert et al., 1997); a survey of adults in Toronto (Locker & Grushka, 1987); and studies on temporomandibular joint disorder, or TMD, reviewed by LeResche (1997).

Slide 8

Chronic Orofacial pain

  • The cost of chronic pain is estimated to be about $80 billion per year, 40% associated with orofacial pain (Israel & Scrivani, 2000; Friction & Schiffman, 1995).

  • The two most prevalent sources of chronic orofacial pain are temporomandibular joint disorder (TMD) and burning mouth syndrome.

http://drc.hhs.gov/report/pdfs/section10-orofacialpain.pdf

Slide 9

Chronic Orofacial pain

  • TMD consists of jaw joint pain and dull facial pain in the temporomandibular joint and the muscles of mastication. Chronic TMD is estimated to affect from 3% to 12% of the U.S. population (Klausner, 1995).

  • Burning mouth syndrome is characterized as a burning, tender, or annoying sensation in the mouth with no apparent mucosal lesion.

  • In 1989, the prevalence of jaw joint pain, burning mouth, and dull facial pain in the U.S. population was 5.3%, 0.7%, and 1.5%, respectively.

Slide 12

Acute orofacial pain

  • Acute orofacial pain includes tooth pain and painful sores or irritations of the mouth.

  • Tooth pain is often caused by dental caries but may also be due to periodontal disease.

  • Tooth pain can interfere with work and social activities, promote anxiety, and result in economic costs.

Slide 13

Acute orofacial pain

  • Data from the 1989 NHIS Orofacial Pain Supplement indicate that the overall prevalence of tooth pain and of mouth sores in the United States was 13.6% and 8.4%, respectively.

  • The prevalence of tooth pain was higher among adults 20 to 64 years of age than among those 65 and older, those with lower education, poorer people, and those who visited a dentist within the past 12 months. (Vargas et al. 2000 and Lipton et al. 1993)
