Classification and Treatment of the Anterior Maxillary Dentition Affected by Dental Erosion: The ACE Classification

Erosive tooth wear is a serious problem with very costly consequences. Intercepting patients at the initial stages of the disease is critical to avoid significant irreversible damages to their dentition and to benefit from still favorable conditions when it comes to clinical performance of the restorative measures proposed. In this article, a new classification is proposed to quantify the severity of the dental destruction and to guide clinicians and patients in the therapeutic decision-making process. The classification is based on several parameters relevant for both the selection of treatment and the assessment of the prognosis, such as dentin exposure in the palatal tooth contact areas, alterations at the level of the incisal edges, and ultimately, loss of pulp vitality.
