Impact of HIV on the practice of dentistry in Houston, Texas.

Abstract

Texas ranks fourth in the nation in the number of documented HIV-infected and AIDS cases. The city of Houston has the highest prevalence of HIV-infected and AIDS cases in Texas. Dental health personnel have an ethical and legal obligation to provide dental services for HIV-infected persons. The purpose of this study was to assess the impact of HIV on the practice of dentistry in Houston. The study population was all dentists with a current Houston practice address registered with the Texas State Dental Board. A 41-item questionnaire was mailed to a stratified random sample of 500 dentists in Houston. The questionnaire covered four main areas: demographics, knowledge, attitudes, and behavior. About three-quarters of the dentists said they had treated an AIDS or HIV+ patient. Sixty percent of the dentists were not aware that breastmilk is a mode of transmission of HIV. There was a significant correlation between "ever treated" an HIV+ patients and "willingness to treat" an AIDS or HIV+ patient (p < 0.01). The experience of treating HIV-infected patients has a greater impact than knowledge alone in influencing dentists' behavior towards AIDS/HIV+ patients.
