What strategies can we implement to treat carious lesions and prevent their recurrence, rather than just focusing on performing restorations? Is there a clinical protocol to practically determine the stages of severity of dental caries and establish treatment and prevention measures? These are the questions answered by the authors in the first part of this volume. The second part is devoted to whitening techniques and the treatment of dental discolorations, true therapeutic and not pure cosmetic procedures that require an understanding of when and why such techniques should or should not be performed. This text aims to be a practical clinical handbook, enabling dentists and dental hygienists to expand their knowledge of cariology and whitening based on the authors' experience and the guidelines found in the literature and recognized internationally. The volume is enriched with an insert on dental photography and an online section with videos, clinical cases and insights, accessible via QR code or by registering on the dedicated website https://blackandwhite.edrapublishing.com.
