Objective: To compare identification of oral candidiasis (OC) and oral hairy leukoplakia (OHL) by medical examiners and oral/dental examiners and to assess the impact of these diagnoses on the medical staging of the human immunodeficiency virus (HIV).
Design: Retrospective analysis of data collected by medical and oral/dental examiners at the baseline examination of a prospective study.
Setting: Homosexual men and men and women who were parenteral drug users residing in New York City, enrolled in a longitudinal cohort study.
Subjects: A total of 245 individuals participated in this study.
Main outcome measures: The diagnoses of OC and OHL as recorded in the medical and oral/dental charts were analyzed retrospectively for the same medical and oral/dental evaluation visits. The medical staging of HIV infection based on that evaluation was analyzed concomitantly.
Results: Among homosexual men, the oral/dental examiners diagnosed OC in 11% of the individuals and the medical examiners in 4%. In the same cohort, OHL was diagnosed by the oral/dental examiners in 14% of the individuals and by the medical examiners in 8%. Among the parenteral drug users the oral/dental examiners diagnosed OC in 29% of the individuals while the medical examiners made this diagnosis in 11%. In the same cohort, OHL was diagnosed by the oral/dental examiners in 9% of the individuals and by the medical examiners in 2%. The OC and OHL diagnoses affected the medical staging of 12% of the HIV-positive homosexual men and of 22% of the HIV-positive parenteral drug users. Forty percent of the HIV-positive homosexual men and 79% of the HIV-positive parenteral drug users with stage-defining oral lesions were not properly identified by the medical examiners.
Conclusions: Specific training and a comprehensive oral examination have a significant impact on the diagnoses of OC and OHL, and on the medical staging of individuals with HIV infection.
