Background: The use of liquid pharmaceutical preparations is a daily occurrence for some children. Evidences show a significant relation between the intake of oral sucrose based medicines and an increase incidence in dental caries. Aim: This in vitro experimental study evaluated the Total Soluble Solids Content (TSSC) by means of Brix scale refractometry and the endogenous pH of antimicrobials of pediatric use presented as oral suspensions. Materials and Methods: Nine medications (6 chemotherapics and 3 antibiotics) were evaluated by random experiment with 3 repetitions for each sample. The analysis of TSSC readings were performed by Brix refractometry using the Abbé refractometer, and the pH values were determined by potentiometry. Results: The mean TSS contents ranged from 11.73 (Keflaxina) to 63.83 (Azitromed). The minimum and maximum mean pH values were 4.12 (Keflaxina) and 10.97 (Zitroneo), respectively. Conclusions: The chemotherapic antimicrobials evaluated in this study presented the highest TSSC means, while the antibiotics showed pHs below the values considered as critical, which may contribute to the development of caries lesions in case of inadequate administration of these medications to children.
