BALLADARES, A  e  BECKER, M. In-vitro effect of five different types of commercial carbonated drinks and juices available in Paraguay on the dental enamel. Mem. Inst. Investig. Cienc. Salud [online]. 2014, vol.12, n.2, pp.08-15. ISSN 1812-9528.

Dental erosion is an affection that consists in the loss of mineralized dental tissues due to chemical processes caused by acids from intrinsic or extrinsic sources, and which is increasing in frequency. The main objective of this cross-sectional in vitro experimental study was to determine the effect of five carbonated drinks and commercial juice drinks on dental enamel, by means of controlled exposure during four weeks on 50 human ex vivo premolars. After measurements with a model 1641072 Nikon stereoscope were completed, it was found that that 100% of the studied drinks, Coca Cola®, Niko Naranja®, Pulp Pomelo®, Frugos Naranja®, and Puro Sol Naranja® had erosive effect on dental enamel (p<0.05), with lesions starting at the second week of exposure. During week 1 of exposure, it was observed that the enamel of all the dental stages subjected to the five drinks was within the score 0 (zero), which means that the enamel remained smooth and glossy. During week 2, the enamel became rough and opaque (score 1). During week 3, dental stages of score 3 started to develop (rough, opaque, substance loss), and during week 4 these score 3 stages predominated. It was observed that Coca Cola® and Niko Naranja® were the drinks that most frequently produced the most severe lesions such as substance loss (score 3). It is concluded that the kind of drink and the frequency of consumption have an effect on dental enamel, and it is necessary to warn patients about such problem in order to reduce risks on the integrity of dental enamel and thus preserve the health of dental pieces.
