| abstract |
Hardenable and hardened dental compositions, and articles including such hardenable and hardened compositions, are provided. In some embodiments, the hardenable dental compositions include an acid-generating component and an acid-reactive component including one or more acid-reactive groups. Upon irradiating, and optionally heating, the hardened compositions are useful, for example, for reducing the bond strength of orthodontic appliances adhered to tooth structures with the hardened compositions. |
