Description
Technical Field
The invention belongs to the field of tooth whitening, and particularly relates to a degradable tooth whitening material, and preparation and application thereof.
Background
Tooth whitening is a major concern for modern people regarding tooth health, and many people are not satisfied with their own tooth color due to smoking, drinking, drug use, genetic factors, and the like.
At present, the most common whitening agent is peroxide, the main component of the whitening agent is generally acidic agent or strong oxidant, and the acid etching effect or oxidation effect is utilized to remove foreign materials adhered to the surface of the teeth, so that the substances destroy the foreign materials on the surface of the teeth, and the substances have obvious whitening effect but stimulate the oral cavity due to the corrosion effect. In addition, since the dental material itself is an inorganic material, damage to the dental material itself may be caused by corrosion or oxidation. Finally, the existing several whitening materials have larger defects, and the whitening effect of the tooth body cannot be realized on the premise of smaller influence.
In view of the above drawbacks, publication No. CN110464674a discloses a tooth whitening product containing a piezoelectric material, which indicates that the piezoelectric material containing a piezoelectric effect is used as a whitening component of the tooth whitening product, and the piezoelectric property of the piezoelectric material is activated by the tooth whitening product contacting the teeth and applying pressure on the surfaces of the teeth, so that a large number of active groups are generated, stains on the surfaces of the teeth are degraded, and whitening of the teeth is achieved; the product does not harm the tooth structure, but the disclosed material with piezoelectric effect is selected from one or more materials of BaTiO3, gaN, znSnO3, (Na, K) -NbO3, znO, lead zirconate titanate, lead magnesium niobate, polyvinylidene fluoride and polyvinylidene fluoride, such as lead magnesium niobate lead titanate; since the piezoelectric material contains lead and is non-degradable, there is a potential hazard to human health; moreover, the piezoelectric materials need to be polarized to achieve good whitening effect; furthermore, the piezoelectric material is selected so that the tooth color is only significantly whitened under high-power, high-frequency vibration operating conditions (e.g., 40W,1000 Hz); these factors limit the scope of use.
