Summary:
Dental erosion is a common problem in modern societies, owing to the increased consumption of acid drinks such as soft drinks, fruit juice and sports drinks. Sports drinks cause the body to maintain proper hydration and supplement minerals which are lost in sweat during excessive exercising. Aside from the benefits of isotonic drinks, it is important to be aware of the harmful effects of citric acid within the products, which could cause enamel and dentin erosion.
In recent years, significant changes have occurred in the treatment of erosive lesions. The modern approach concentrates at the non-invasive treatment of the early erosive lesions. The most commonly used agent for years, was fluoride. Though, at the last decade, it was suggested the use of a new means of preventing erosive lesions, the casein phosphopeptide amorphous calcium phosphate nanocomplex.
The protective role of CPP-ACP is based on the physical principle of forming a structural unit of hard dental tissues. To form one unit cell of hydroxyapatite, in order to restore an erosed dental surface, are required 10 calcium ions and 6 phosphate ions [Ca10(PO4)6F2]. The CPP-ACP complex stabilizes the ACP to the tooth surface, increasing the availability of calcium and phosphorus.
CPP-ACP has been incorporated in dental materials, foods and oral hygiene products. The research over that technology, such in vitro studies, as clinical trials, has shown significant re-mineralization of enamel surfaces. However, research on dentin sections is limited.
The aim of this in vitro study was to evaluate the influence of energy drinks on dentin surfaces. There was evaluated the possible erosive action of three different sports drinks (Red Bull, Lucozade, Monster) over dentin speciments. The speciments were exposed to sports drinks for 10 min. daily, for a period of 14 days.
There was also tested the potential role of the commercial formulation Tooth Mousse of the company GC, containing CPP-ACP over dentin speciments. The CPP-ACP paste was placed to dentin samples that were exposed to sports drinks after the placement of the agent, so as to prohibit demineralization.
Micro-hardness measurements were performed before and after the immersion to sports drinks, with or without the placement of CPP-ACP paste.
The results of statistical analysis showed that one single application of the factor was not enough to protect surfaces of dentin against in vitro demineralization due to sports drinks.
Furthermore, there was no statistically significant difference of the demineralization of the dentin samples after the application of the agent, compared to the demineralization which occured after placing the samples to sports drinks solution.
In conclusion, the protective role of Tooth Mousse over dentin surfaces is not supported by this in vitro study.
