An orthodontic adhesive includes components capable of allowing easy debonding of an orthodontic device from a patient's tooth. The adhesive includes an engineered marine mussel protein. The adhesive may include at least one photocleavable moiety. The adhesive is applied in one or more individual layers. One of the components of the adhesive is capable of binding to a tooth and the other component may be capable of binding to an orthodontic device. A method of adhering an orthodontic device to a tooth includes applying a layer of an orthodontic adhesive to either the tooth or the orthodontic device or the tooth and the orthodontic device and affixing the orthodontic device to the tooth with the orthodontic adhesive situated between the tooth and the orthodontic device. The engineered marine mussel protein includes one or more catechol moieties or one or more derivatives of a catechol moiety.

The invention relates to a dentin collagen fibril demineralizing material, and a preparation method and application thereof. The invention relates to a conjugate of water-soluble chitosan and an aminocarboxylic acid metal chelating agent used for dental demineralization, preferably dentin demineralization. The invention also discloses a dentin collagen fibril demineralizing material and a preparation method and application thereof, wherein the material is prepared from 0.5-1 part by mass of water-soluble chitosan, 10-30 parts by mass of EDTA, and 0.8-1.5 parts by mass of cross-linking agent. The invention relates to a dental demineralization composition comprising a conjugate and a material of the invention. The conjugate, material and composition can be used for dentin demineralization treatment before dental bonding and restoration. When used as a dentin collagen demineralizing agent, they have excellent selective extrafibrillar demineralization performance, good biological compatibility, effective anti-bacterial activity, endogenous matrix protease-inhibiting activity and extremely low cytotoxicity.
