Técnicas de clareamento dental em dentes escurecidos extrínsecamente – uma revisão de literatura

Abstract

Introduction: Extrinsic dental darkening is a widely recognized problem, resulting from external factors such as consumption of pigmented drinks and smoking. This stain alters the natural color of the tooth and negatively impacts the aesthetics of the smile and the self-esteem of individuals. In this context, tooth whitening is a solution to restore the natural color of teeth, improving self-esteem and aesthetics. Objective: This work aims to carry out a literature review on tooth whitening techniques to treat extrinsic tooth darkening, evaluating the effectiveness, safety and durability of each method. Methodology: A search was carried out in the PubMed databases, using the terms “tooth whitening” and “darkened teeth”, prioritizing articles published from 2008 to the present year. Results: The results indicate that the evaluated techniques are effective in removing extrinsic stains, with variations in the speed and intensity of whitening. The safety and durability of results vary depending on the technique and patient ollaboration. Conclusion: The various tooth whitening techniques are effective in treating extrinsic tooth darkening, each with its own particularities. Choosing the most appropriate one must consider the individual needs and preferences of patients, as well as professional guidance.
