The attention of dentists in restoring the shape and function of teeth is today the main focus of prosthetic rehabilitation. However, we often forget to analyze in depth the causes of erosion and abrasion of dental enamel. Saliva is one of these causal factors, which must be analyzed and known in order to preserve prosthetic restorations in the long term. In this webinar we will talk about what is the real causal therapy of caries risk factors and enamel erosion, providing practical guidelines on how to perform salivary tests in the office and follow patients over time.
