Introduction: saliva reflexes the physiological conditions of organism through determinations of hormones, immunoglobulins and drug monitoring, but there is not data referred to the presence of lipoproteins in human saliva. Objective: to determinate the presence of lipoproteins in human saliva. Method: human saliva samples of both sexes with ages between 16 and 52 years old were collected according to international standars. The determinations of apolipoproteins A and B were made on saliva supernatant obtained by centrifugation (800xgx10min), measured in autoanalyser through inmunoturbidimetric test and expressed as average (mg/dL) +/- D.S. Results: the level of apolipoprotein B in women was 11.25 +/- 3.2 and in men 17 +/- 2.79. Apoliprotein A was not detected in any sample. Discussion: the results found are the first data of existence of lipid carrier in saliva. It should be adjusted to protocol to enlarge essays and make correlations with serum apolipoproteins.
