title: Contemporary trends and techniques in tooth whitening: a review.
abstract: The popularity of tooth whitening has increased with the advent of patient-applied, peroxide-based whitening agents, as well as increased media influence. Peroxides are considered effective and safe when used under professional supervision. Whitening methods include those prescribed by a dental professional for the patient's at-home use, those applied by the dental professional in the office, a combination of both, or methods available over the counter (OTC).
