A single and dual component dental composite restorative featuring anti-microbial and low Coefficient of Thermal Expansion (CTE) compounds is disclosed. The exemplary anti-microbial compound is zinc oxide. The CTE of the dental composite restorative is the same as, or substantially similar, to that of dentin. By maintaining a CTE substantially similar to that of dentin, the Margin Percolation phenomenon is minimized, which decreases the incidence of secondary caries.

Apparatus and methods for removing a dental crown from a tooth. Chemical bonds within an adhesive, between the adhesive and the crown, and between the adhesive and the tooth may secure the crown to the tooth. The chemical bonds may be weakened. After weakening the bonds, the crown may not be securely affixed to the tooth. After weakening the bonds, the crown may be easily removed from the tooth. The bonds may be weakened by applying ultrasonic waves to the adhesive. Sonic energy of the waves may heat the adhesive. The bonds may be weakened by positioning the adhesive within an electric field. The bonds may be weakened by applying heat to the adhesive. The heating may cause particles within the adhesive to expand. The electric field and/or the sonic energy may be applied via an electronic tool.

Filmogenic compositions are described for topical anaesthetic bioadhesives (TABs) comprising a) a xanthan biopolymer matrix selected from Xanthomonas species and pathovars, including Xanthomonas campestris pathovars campestris and maninhotis, and Xanthomonas arboricola pathovar pruni, a producer of pruni xanthan, wherein the matrix is made of pure or combined xanthan varieties in any proportion, said matrix comprising between 1% and 95% by weight of the total weight of the composition, and additives or excipients; b) at least one anaesthetic, in a proportion of 0.1% to 50% by weight of the total weight of the composition. The topical anaesthetic bioadhesives (TABs) are also described, and they may be applied to the gingival mucosa and/or alveolar mucosa on the buccal (1) or lingual/buccal (2) surfaces with extensions and anatomical contours for crowns of the upper and lower dental arches.

A dental self-adhesive resin cement is provided comprising a two-component system. A first catalyst component includes one or more acidic monomers. A second base component includes one or more basic fillers. The mixture of the first and second components is polymerizable and has an initial pH that is acidic immediately after mixing and a pH of at least about pH 8 after polymerization.

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.
