Methamphetamine abuse: medical and dental considerations.

Amphetamines are central nervous system stimulants with high abuse potential and intense physiological and psychological effects. Abuse of methamphetamine--a methyl derivative of amphetamine--has grown to epidemic proportions across the United States. Due to the characteristic signs of methamphetamine abuse that appear in the oral cavity dentists should have a heightened awareness of the medical and dental issues surrounding this dangerous behavior. Moreover, recognition and proper referral to treatment should be a part of every provider's plan for preventing the devastating psychological, oral, and overall systemic effects of methamphetamine abuse.
