Aesthetic and functional enamel parameters, such as colour stability and dentinal sensitivity, are key indicators of oral health and patient quality of life. Modern dentifrices often combine whitening, remineralizing, and desensitizing components, yet long-term comparative evaluation of their optical and electrofunctional effects remains limited. Aim – to assess changes in colour (saturation, brightness, whiteness, and yellowness indices) and electroodontometric parameters of permanent teeth in adults using toothpaste formulations with different ratios of whitening, remineralizing and desensitizing agents over short- and long-term periods.

Materials and methods. The study population comprised adults allocated into four groups, with each group assigned a toothpaste formulation differing in its predominant whitening, remineralizing or desensitizing effect. Optical enamel characteristics were measured by spectrocolourimetry, and pulp excitability was determined using electroodontometry at baseline and after 1, 3 and 6 months of product use.

Results. Toothpastes with predominant whitening–remineralizing action produced a significant reduction in colour saturation and yellowness with a stable increase in brightness and whiteness from the first month of use, maintaining the effect throughout the observation period. In contrast, formulations with a dominant desensitizing component provided moderate optical improvement but demonstrated a pronounced increase in pulp excitability, indicating activation of reparative tissue responses.

Conclusions. Dentifrices with varying combinations of whitening, remineralizing and desensitizing agents exert differential effects on enamel and pulpal tissues, supporting an individualized selection strategy depending on the intended clinical outcome – aesthetic enhancement or functional recovery.

Key words: middle-aged adults, toothpaste, dentin hypersensitivity, spectrocolourimetry, electroodontometry.
