HIV Status and the Risk of Post-extraction Complications

Division of Oral/Maxillofacial Surgery, Department of Surgery, Emory University School of Medicine, Atlanta, Georgia

Tooth extraction is commonly performed for patients infected with the human immunodeficiency virus (HIV). We undertook a prospective study to determine if HIV-positive patients had an increased risk for complications following tooth extraction. The study sample was composed of patients who presented for tooth extraction to the outpatient oral/maxillofacial surgery clinic at Grady Memorial Hospital, Atlanta, GA. The predictor variable was HIV status (positive or negative). The outcome variable was the presence or absence of a post-extraction complication. Other study variables were grouped into the following sets: (1) demographic, (2) past medical and social history, (3) clinical, (4) laboratory values, and (5) treatment. Between 11/93 and 4/96, 166 patients were enrolled. The study sample was composed of the 151 patients who completed the study protocol and consisted of 76 HIV-positive and 75 HIV-negative patients. The post-extraction complication rates were 22.3 and 13.3% for the HIV-positive and -negative groups, respectively (relative risk = 1.68, 95% confidence interval = 0.82 to 3.42, p = 0.15). The types of complications that occurred were similar in both groups. While the data suggest an increased rate of post-extraction complications in the HIV-positive group, the difference in complication rates between the two groups was not statistically significant. In addition, the complications were minor, self-limiting, and readily treated. Based on these findings, we believe that tooth extraction is a low-risk procedure in HIV-positive patients. Treatment may be rendered routinely to patients who present on an outpatient basis without the need for an extensive pre-operative work-up, unless otherwise indicated by relevant history.
