Dental discoloration in adolescents represents one of the most common esthetic problems in modern dentistry and significantly affects psychosocial well-being and quality of life. According to Joiner (2004, 2006), even minor changes in tooth color are visually perceptible and influence patient satisfaction, while Paravina and Powers (2008, 2012) emphasize that objective, scientifically validated methods are required for reliable color assessment.
Traditional visual shade determination is subjective and influenced by lighting conditions, clinician experience, and fatigue (Chu et al., 2010; Hasegawa et al., 2000). Digital technologies, such as spectrophotometry and digital colorimetry, based on the CIE L*a*b* color system (O’Brien, 2005), provide accurate, reproducible, and quantitative evaluation of tooth color changes. Color differences can be calculated using the ΔE parameter, with ΔE > 3.3 considered clinically perceptible (Johnston & Kao, 1989; Paravina et al., 2015).
Digital monitoring at multiple stages of treatment allows dynamic assessment of therapeutic effectiveness, objectively detecting even minimal improvements. Studies by Kim-Pusateri et al. (2009) and Vichi et al. (2011) demonstrated that digital devices significantly outperform visual methods in accuracy and reproducibility. Integration of digital color measurement into adolescent dental practice enhances evidence-based treatment planning, optimizes minimally invasive interventions, and strengthens the scientific validity of clinical outcomes.
