Lack of evidence for patient-to-patient transmission of HIV in a dental practice.

This report reviews data pertaining to the hypothesis that transmission of HIV to five patients of a Florida dentist with AIDS resulted from the patient-to-patient transfer of infectious materials through the reuse of contaminated instruments. Findings strongly suggest that patient-to-patient transmission of HIV through contaminated handpieces, prophylaxis angles or anesthetic needles or cartridges did not occur in this practice.

Transmission of human immunodeficiency virus in a dental practice.

OBJECTIVE: To determine if patients of a dentist with the acquired immunodeficiency syndrome (AIDS) became infected with human immunodeficiency virus (HIV) during their dental care and, if so, to identify possible mechanisms of transmission. DESIGN: Retrospective epidemiologic follow-up of the dentist, his office practice, and his former patients. SETTING: The practice of a dentist with AIDS in Florida. PARTICIPANTS: A dentist with AIDS, his health care providers and employees, and former patients of the dentist, including eight HIV-infected patients. MEASUREMENTS: Identification of risks for HIV transmission (if present), degree of genetic relatedness of the viruses, and identification of infection control and other office practices. RESULTS: Five of the eight HIV-infected patients had no confirmed exposures to HIV other than the dental practice and were infected with HIV strains that were closely related to those of the dentist. Each of the five had invasive dental procedures, done by the dentist after he was diagnosed with AIDS. Four of these five patients shared visit days (P greater than 0.2). Breaches in infection control and other dental office practices to explain these transmissions could not be identified. CONCLUSION: Although the specific incident that resulted in HIV transmission to these patients remains uncertain, the epidemiologic evidence supports direct dentist-to-patient transmission rather than a patient-to-patient route.

The assessment of nursing caries and its relationship to high caries in the permanent dentition.

The prevalence of nursing caries has been found to be high in populations of Native American children, unlike other US population groups. Comparisons among studies are difficult because a variety of operational definitions of the syndrome have been used. This study had two goals. First, a retrospective dental record audit was conducted for a Native American population attending Head Start in 1977-78, to compare the prevalence rates of nursing caries obtained by using different nursing caries classification schemes. Second, we studied the relationship of prior nursing caries to current high caries level determined by a clinical exam in the same children approximately ten years later (N = 88). As expected, different classification schemes yielded different prevalence rates. Classification of nursing caries by buccal or lingual caries in the maxillary incisors found 45 percent of the children with the disorder, vs 61 percent if measured by three or more carious maxillary incisors, or 76 percent if two or more carious maxillary incisors. Nursing caries in these Head Start children, defined by caries on the buccal or lingual surfaces of the maxillary incisors, showed no increased risk of greater than or equal to 5 DMFT at age 15. The Head Start children classified as having nursing caries by two or more, or three or more, decayed maxillary anterior teeth had relative risks (RR) of 1.6 (95% Cl 1.1, 2.4) and 1.4 (95% Cl 1.0, 1.9) for high caries (DMFT greater than or equal to 5) ten years later, whereas the RR for children with a dmft greater than or equal to 5 was 2.4 (95% Cl 1.4, 4.3).(ABSTRACT TRUNCATED AT 250 WORDS)
