Effects of oral hygiene products containing lactoperoxidase, lysozyme, and lactoferrin on the composition of whole saliva and on subjective oral symptoms in patients with xerostomia



Effects of oral hygiene products containing lactoperoxidase, lysozyme, and lactoferrin on the composition of whole saliva and on subjective oral symptoms in patients with xerostomia



Acta Odontologica Scandinavica 54(6): 391-397



This study evaluates the effects of two oral hygiene products containing nonimmunoglobulin antimicrobial agents on whole saliva and on subjective oral symptoms in patients with xerostomia. Twenty patients used a lactoperoxidase-system-containing toothpaste (Biotene) combined with the use of a mouthrinse (Biotene), comprising also lysozyme and lactoferrin, for 4 weeks. Saliva samples were collected at base line, after 4 weeks' use of the products, and at the end of a 4-week washout period. Samples were analyzed for selected biochemical and microbiologic factors. The effects on subjective oral symptoms were also recorded. A 4-week daily use of toothpaste and mouthrinse relieved the symptoms of oral dryness in 16 patients. The levels of salivary hypothiocyanite, lysozyme, lactoferrin, or myeloperoxidase activity did not change, but there was a significant decrease in salivary pH (P < 0.05), total peroxidase activity (P < 0.05), and total protein content (P = 0.01). In patients with the lowest salivary flow rates (n = 5) a significant (P > or = 0.04) increase was detected in salivary hypothiocyanite concentrations. No major changes occurred in salivary microflora. The products relieved subjective oral symptoms in most xerostomic patients, but this was not necessarily related to the presence of antimicrobial agents.
