Minocycline-induced intraoral pharmacogenic pigmentation: case reports and review of the literature.
Minocycline, a semi-synthetic tetracycline antibiotic, is well documented as being associated with pharmacogenic pigmentation of various tissues in humans and other mammals. The most obvious of these are skin pigmentation, but intraorally include "green" roots of erupted teeth, "black" roots of extracted teeth, a dark stain of the crowns of fully developed teeth, and "black" alveolar bone. This article presents five cases of "black" alveolar bone with photographic documentation of its progress. It also reviews the available English language literature on this phenomenon. The incidence of minocycline staining of alveolar bone is probably 2% of that population taking the drug for 2 months or longer. Presently, minocycline is most widely used in the young adult population for the treatment of acne. With the recent interest in minocycline as a palliative treatment for rheumatiod arthritis, an entirely different population could be experiencing this effect. If minocycline use becomes widespread as a treatment for rheumatoid arthritis, it is likely that more practitioners will be asked to diagnose this sometimes striking, though apparently benign, condition. Recognition of this condition will save the practitioner and the patient from unnecessary concern and surgery.
