Polyphenols for Preventing Dental Erosion in Pre-clinical Studies with in situ Designs and Simulated Acid Attack.

Dental erosion is a chemical process characterized by acid dissolution of dental hard tissue, and its etiology is multifactorial. Dietary polyphenols can be a strategy for dental erosion management, collaborating to preserve dental tissues through resistance to biodegradation. This study describes a comprehensive review to interpret the effects of polyphenols on dental erosion of pre-clinical models with designs and simulated acid attacks on enamel and dentin samples.

A conservative treatment approach using direct composite resins for anterior teeth eroded by lemon sucking.

An excessively acidic diet results in the progressive deterioration of dental health, with functional, esthetic, and biological consequences. Previously, rehabilitation required placing numerous full crowns and root canal treatments; however, with improved adhesive techniques, a more conservative approach may be utilized to preserve tooth structure. This article describes 2 cases that utilized conservative dental treatments (involving direct composite resins with minimal preparation of the tooth structure) to treat eroded dentition induced by lemon sucking.

Restoring esthetics in eroded anterior teeth: a conservative multidisciplinary approach.

Consuming a highly acidic diet can lead to erosion or excessive wear of dental hard tissues, resulting in the need for oral rehabilitation. Previously, a severely eroded dentition could be rehabilitated only by extensive crown and bridge placement or by removable partial dentures. However, developments in adhesive dentistry have made it possible to restore the esthetics and function of eroded teeth in a minimally invasive manner.
