Abstract
Tooth discoloration represents a complex challenge in aesthetic dentistry, resulting from a wide spectrum of intrinsic and extrinsic factors, including enamel defects and alterations related to vital and non-vital teeth. A thorough understanding of the biological mechanisms governing color expression in enamel and dentin is essential for achieving predictable and durable aesthetic outcomes.This lecture analyzes the etiology of tooth discoloration, with particular emphasis on enamel defects, chromophore dynamics, and the structural differences between vital and non-vital teeth. A structured diagnostic workflow is presented to support accurate classification and appropriate treatment planning.Contemporary aesthetic strategies are discussed, ranging from minimally invasive whitening protocols to restorative and prosthetic solutions, guided by optical principles, material science, and tissue preservation. Clinical cases demonstrate how biological insight enables effective aesthetic control, even in complex discoloration scenarios.By integrating biology, diagnosis, and modern aesthetic techniques, this presentation provides clinicians with a scientifically sound framework for managing tooth discoloration with precision, consistency, and respect for dental tissues.
