Effectiveness of an Oral Moisturizer with Malic Acid/Xylitol as Anti-caries Therapy in Children

Objective: To determine the effectiveness of an oral moisturizer containing malic acid/xylitol as anticaries therapy in 5-year-old children free of caries and at different levels of the Simplified Oral Hygiene Index (OHI-s). Materials and methods: Randomized uncontrolled clinical trial in 96 salivary samples from children divided into two groups of 48 children with acceptable (n = 16), deficient (n = 16) and adequate (n = 16) s-OHI, with one and two applications of the moisturizer per group per day, for 21 days. The effectiveness was evaluated according to the salivary profile (salivary volume, salivary flow, Streptococcus mutans count, salivary pH, buffer capacity and fluoride level). Results: With an application at the appropriate level of OHI-s there was a positive change in salivary volume (7.5 ml) and pH (7.47), at the acceptable level its effectiveness was manifested in the pH (7.51), and buffer capacity (7.22), and at the deficient level in buffer capacity (6.23). With two applications, it is efficient in all the components of the salivary profile, except for the level of fluoride and the count of Streptococcus mutans for the 3 levels of OHI-s. Conclusions: Two daily applications of Xeros Dentaid (R) Spray have a positive effect on salivary profile values and can be used as anti-caries therapy.
