Botox and Antibiotics in Dentistry

Botox is injected to remove wrinkles from face. I have read that some dental clinic also offer this service in their clinic. To learn more about botox CLICK HERE.

There is an interesting article published in Feb 2008 issue of American Journal of orthodontics and DO about use of BOTOX in cases of upper short lip. Effects of botox treatment last only about 4 months. They concluded: BTX-A injections for the neuromuscular correction of gummy smiles caused by hyperfunctional upper lip elevator muscles was effective and statistically superior to baseline smiles, although the effect is transitory.
Full abstract is here.

But now FDA has issued warning on use of BOTOX and similar products, read on:

The popular anti-wrinkle drug Botox and a competitor have been linked to dangerous botulism symptoms in some users, cases so bad that a few children given the drugs for muscle spasms have died, the government warned Friday 8 Feb, 2008.

The U.S. Food and Drug Administration's warning includes Botox, a wrinkle-specific version called Botox Cosmetic, and its competitor, Myobloc, drugs that all use botulinum toxin to block nerve impulses, causing them to relax. Full news here.

Antibiotics before Dental procedures are not needed in most patients:

According to new guidelines, far fewer people need preventive antibiotics before dental procedures than previously recommended, according to the February issue of Mayo Clinic Women's HealthSource.

The use of preventive antibiotics for people with certain heart conditions stemmed from worries about endocarditis. That condition is an infection of the thin membrane that lines the chambers and valves inside the heart, called the endocardium. Endocarditis occurs when bacteria or germs from another part of the body, such as the mouth, enter the bloodstream and travel to the heart and attach to abnormal heart valves or damaged heart tissue.

"Preventive antibiotics before dental work are now recommended only for people who, if they develop endocarditis, are more likely to die or have serious complications," says Walter Wilson, M.D., an infectious diseases specialist at Mayo Clinic. Dr. Wilson headed the AHA committee that recently revised the guidelines.

Preventive antibiotics are no longer recommended for many people who have common heart conditions such as mitral valve prolapse or rheumatic heart disease. Before their next dental visit, patients who have taken preventive antibiotics should check with a doctor or dentist to discuss the guideline changes and determine if the medication is necessary.
