Yakubiv Ekaterina Vladimirovna

In recent years, the demand for aesthetic dentistry, particularly teeth whitening, has significantly increased. The aim of this article is to provide a comprehensive analysis of the effectiveness of various teeth whitening methods based on modern scientific data. The review covers over-the-counter products, at-home methods with custom trays, professional in-office bleaching, laser technologies, and combined protocols. Materials and methods included a systematic search in PubMed, Scopus, and Web of Science, selecting randomized controlled trials, meta-analyses, and clinical studies. The results showed that professional methods, especially in-office bleaching and combined approaches, offer the highest effectiveness (ΔE > 6.0) and long-lasting results (up to 12–18 months). Over-the-counter products demonstrate limited efficacy (ΔE 1.0–2.5), while at-home methods occupy an intermediate position. The discussion emphasizes the importance of individualized method selection based on clinical conditions, tooth sensitivity, and patient compliance. In conclusion, teeth whitening remains a highly sought-after procedure, and future research may focus on developing personalized approaches.
