Abstract: Described herein are inventive compositions and methods relating to polymer conjugates and, in particular, to polymer conjugates having pendant side groups comprising ring moieties. In one aspect, embodiments are generally related to compositions that mimic naturally-occurring polyphenol compounds. The compositions comprise, in some embodiments, a polymer backbone having a plurality of hydroxyaromatic pendant side groups or derivatives thereof. For example, in some cases, a pendant side group may be a phenol or a substituted derivative thereof. In some cases, the pendant side group may be an oxidized hydroxyaromatic group, such as a quinone. In some embodiments, self-assembled structures comprising one or more of the polymer conjugates are provided. For example, the polymer conjugates may be combined with a complexing agent to form a particle. In some cases, a polymer conjugate may form a hydrogel.

Abstract: An improved method for cleaning teeth is disclosed. The method for cleaning teeth includes: applying ultrasonic waves of a first frequency through a liquid media to the teeth for a first period of time; and applying ultrasonic waves of a second frequency through a liquid media to the teeth for a second period of time.
