A study reported in the Journal of Periodontology suggests that an injectable contraceptive may be putting some women at an increased risk for gum disease. The women affected are using depot medrooxyprogesterone acetate (DMPA) commonly known as Depo-Provera marketed by Pfizer. According to the study, substances in DMPA may encourage an inflammatory response associated with a higher risk of periodontal (gum) disease.

The study included 4,460 U.S. women who currently use DMPA or who have used it in the past. Significant differences were found in gum pocket depths, gum bleeding, and looseness of the teeth between DMPA users and non-users. Gingivitis (gum disease) was present in 53.9 percent of women who reported using DMPA compared with 46.1 percent of women who had never used DMPA.

The study’s authors concluded that DMPA use was associated with an increased risk of gingivitis and periodontitis (advanced gum disease).

If you use a contraceptive containing DMPA such as Depo-Provera or have used one in the past, you may want to check your gum disease status with your general dentist or periodontist. For a periodontist in the Detroit, Michigan area, contact Joseph R. Nemeth DDS & Associates at 248-357-3100.
