In addition, the peroxide composition may additionally contain triclosan, chlorhexidine, or vitamin E or its derivatives as a medicinal ingredient for treating oral diseases, or peroxide or chlorophyll or its derivatives for removing bad breath ; but considering that hyaluronic acid is only used as a component of humectants, it is mainly used to prevent the composition from drying during distribution, and cannot relieve the side effects of peroxides, and hyaluronic acid is in direct contact with peroxides, which is easy Degraded by peroxides to affect efficacy

[0008] Chinese patent CN 201720034971.7 discloses a cross-linked sodium hyaluronate gel patch, which includes a support layer, a cross-linked sodium hyaluronate layer and a release layer; the support layer has an inner cavity; the inner cavity It is composed of the arc-shaped gel outer layer and the gel inner layer of the support layer. The inner gel layer has a number of small holes, and the inner cavity is filled with a cross-linked sodium hyaluronate layer; the support The layer is placed on the release layer; the utility model has the advantages of being close to the eye skin and easy to penetrate; but considering that cross-linked sodium hyaluronate is a water-insoluble semi-solid gel, it can be combined with uncross-linked hyaluronic acid Compared with the poor transdermal absorption rate, this utility model uses cross-linked sodium hyaluronate to repair skin tissue, and the repair effect is limited

The preparation of the present invention with a high degree of tight binding increases the time of being tightly bound to the target site in the oral cavity, which is beneficial to achieve the desired effect; this patent mainly solves the problem of delivering drugs to the teeth and around the teeth, and does not consider the drug Stimulation to teeth and their surroundings
