Active clinical trials for "Tooth Demineralization"

The aim of this study is to investigate the retention, marginal integrity and potential to prevent lesion progression of a bioactive resin material compared to a conventional resin-based flowable composite during management of initial carious lesion in adult population over an 18 months period.

Evaluate the effectiveness of silver nanoparticles incorporated into the primer orthodontic Transbond XT in preventing enamel demineralization adjacent to brackets.

Treatment with fixed orthodontic appliances is often associated with pain, which poses great challenges in the efficient brushing of the teeth thus making the teeth more vulnerable to plaque formation. Treatment duration with fixed orthodontic appliances usually extends to 18 months or even longer in some cases. This prolonged vulnerability to plaque formation frequently leads to demineralization of teeth. There is also an increase in the number of plaque retentive sites due to the fixed appliances, leading to a rapid change in the bacterial composition of the dental plaque, particularly in the number of acidogenic bacteria. The resulting enamel decalcification is also known as white spot lesions (WSLs), which is an early sign of demineralization of enamel. Enamel WSLs (EWSLs) can be observed even as early as four weeks from the start of fixed orthodontic treatment. The occurrence of EWSLs adjacent to the orthodontic brackets ranges from 15 to 85%. The incidence of EWSLs development is higher in orthodontic patients as compared to the development of similar lesions in non-orthodontic patients. These EWSLs are not aesthetically pleasing and is certainly unacceptable when it develops during fixed orthodontic treatment that is usually performed in patients who often seek such treatment to improve their aesthetics. Additionally, even if the outcome of fixed orthodontic treatment is superior from well-aligned teeth, aesthetics can be greatly compromised with EWSLs. Therefore, the prevention of such lesions is an important concern for orthodontists. Though professionally applied topical fluoride varnish helps in remineralization of EWSLs, an adequate supply of calcium and phosphate ions is essential for remineralization. Therefore, EWSLs on maxillary teeth could be prevented and remineralized by the use of advanced novel topical fluoride varnish with added calcium and phosphate-based delivery system.

Monocentric, randomised, double-blind, cross-over controlled study with two arms. This study aims to analyse the impact on mineralisation of Sugar Free Gum (SFG) containing CPP-ACP in healthy adults.
