Abstract

Acquisition of saliva for biologic, immunologic and chemical analyses has been extremely difficult in infants and young children due to lack of cooperation and motor skills necessary for expectorating adequately. The purpose of this study was to investigate a technique for obtaining satisfactory quantities of whole, unstimulated saliva in the typical dental operatory setting for cytologic, microbiologic and viral evaluation, while requiring minimal cooperation and motor skills from pediatric patients. A low vacuum-assisted aspiration device was utilized to obtain samples from infants and children who were at risk for vertically acquired HIV-infection (age-range 6 mos to 8 yrs). Adequate saliva samples were collected in 175 of 196 (89 percent) attempts in 88 of 89 (99 percent) children (2.3 samples/child). Saliva was not obtained in twenty-one attempts primarily due to xerostomia (62.5 percent). Saliva sample volume obtained was variable, ranging from 1.2 to 3.6 mls with a collection time of approximately three to five minutes. Cell block preparations were made from the saliva, which allowed for cytologic evaluation of sloughed superficial squamous cells, evaluation of oral flora, and detection of yeast and hyphal fungal forms. Adequate volumes of supernate were also available for microbiologic and viral cultures, immunologic studies and PCR study for various viral agents shed in the saliva. Use of a vacuum-assisted collection device for whole unstimulated saliva in infants and young children in the dental operatory setting provides adequate saliva for multiple analyses, which may provide information regarding HIV disease status and early diagnosis of opportunistic infections.
