Dental Health: Local Anesthetic/Vasoconstrictor Precautions

Use with caution; epinephrine, norepinephrine and levonordefrin have been shown to have an increased pressor response in combination with TCAs


Dental Health: Effects on Dental Treatment

Amitriptyline: The most anticholinergic and sedating of the antidepressants; pronounced effects on the cardiovascular system; long-term treatment with TCAs such as amitriptyline increases the risk of caries by reducing salivation and salivary buffer capacity. In a study by Rundergren, et al, pathological alterations were observed in the oral mucosa of 72% of 58 patients; 55% had new carious lesions after taking TCAs for a median of 51/2 years. Current research is investigating the use of the salivary stimulant pilocarpine (Salagen®) to overcome the xerostomia from amitriptyline.

Chlordiazepoxide: Over 10% of patients will experience dry mouth which disappears with cessation of drug therapy
