Results from a 3-year longitudinal study on the oral manifestations of AIDS (OMA) among seropositive children and their siblings indicated poor adherence with recommendations for dental treatment (Broder, Catalanotto, Reisine, & Variagiannis, 1996). The purposes of this study were to (a) to examine oral health behaviors, attitudes, and perceived barriers to care among caregivers of children with HIV and their siblings who were referred for dental care, and (b) develop and evaluate a 5-week summer pilot program to increase adherence with referral for dental treatment. Telephone interviews with caregivers were conducted to identify barriers to care and to implement services to increase attendance in the dental clinic for their children. Interviews were completed with 28 of the 38 (74%) caregivers recruited from the OMA study (previously cited) who had children referred for dental treatment at the final (sixth) oral health research exam. Twelve of their 58 children (21%) had obtained dental care privately, 25 (62.5%) initiated treatment and 2 (6.3%) completed treatment at the referred dental school during the 5-week pilot program. Although caregivers of children with HIV and their siblings were responsive to the initial efforts of the program's service coordinators, follow-up data from the coordinators' records and chart abstraction revealed that the majority of the participants did not appear for their second or third appointments. The interview reports suggested that caregivers expect dental treatment, such as restorations, at each appointment and do not regard exams/treatment planning as treatment. Personal/family and health care delivery system factors were expressed barriers to dental care. Implications for future programs and investigations are discussed

Although it has been established that aspiration of pharyngeal bacteria is the major route of infection in the development of nosocomial pneumonia, colonization of the pharyngeal mucosa by respiratory pathogens has been shown to be a transient phenomenon. It has been suggested that the dental plaque may constitute an additional, possibly more stable, reservoir of respiratory pathogens. The purpose of this study was to assess the prevalence of oral colonization by potential respiratory pathogens in a group of elderly (mean age = 75.9 yrs) chronic-care-facility residents (n = 28) and a group of age-, gender-, and race-matched outpatient control subjects (n = 30), with specific attention to plaque present on tooth, denture, and oral mucosal surfaces. Plaque scores on teeth and dentures were significantly higher in the chronic-care-facility (CCF) subjects than in the dental outpatient control (DOC) subjects (PII 2.3 vs. 1.2 and denture plaque 1.4 vs. 0.3). While no subjects in the DOC group were found to be colonized with respiratory pathogens (> 1.0% of the cultivable aerobic flora), 14.3% (4/28) of the CCF subjects were found to be colonized. Oral colonization with respiratory pathogens in CCF subjects was associated with the presence of chronic obstructive pulmonary disease (COPD) and higher plaque scores. These results suggest that deficient dental plaque control and the presence of COPD may be related to respiratory pathogen colonization of dental plaque in chronic-care-facility residents

The authors investigated the prevalence of xerostomia in a group of 604 subjects participating in a rheumatoid arthritis, or RA, study to explore the relationship of reduced salivary flow symptoms and demographic, clinical and medical characteristics. Forty-three percent of these subjects exhibited one or more severe xerostomia symptoms. Separate analyses revealed that the subjects who had the most physical disease symptoms were at greater risk of having reduced salivary flow. The study's results suggest that patients with RA should be screened for xerostomia symptoms so appropriate clinical interventions can be initiated
