Spectrophotometric assessment of photodynamic teeth bleaching

THE AIM Clinical analysis of the effectiveness of photodynamic tooth whitening according to the spectrophotometric method. MATERIAL AND METHODS Photodynamic tooth whitening was performed in 35 patients aged 20-45 years, on the teeth of the frontal group. To record the optical characteristics of enamel, the spectrophotomerism method was used. RESULTS The study reliably shows that the average change in color saturation «C» ranged from 0.5 to 2 units. The optical characteristic of luminosity "L" before and after photodynamic exposure remained within the limits of healthy enamel, and the optical characteristic of whiteness on the scale of whitened teeth was 2 units. CONCLUSION The method of photodynamic therapy can be used in dental practice to conduct a teeth whitening procedure.
