Objective: This prospective case series aimed to clinically evaluate the bleaching effect, spontaneous tooth sensitivity, and variation in the thermal sensation threshold of different groups of teeth undergoing in-office bleaching.
Method And Materials: Ten patients received conventional bleaching treatment: 35% hydrogen peroxide with three bleaching sessions of 45 minutes, evaluating color change (∆E and ∆E00), Whitening Index (WID), and tooth sensitivity (visual analog scale). Thermal stimulus-generating devices were used to simulate sensitivity caused by low temperatures through quantitative sensory tests.
Article Synopsis
- The study aimed to examine how the structure of different tooth types affects the effectiveness of hydrogen peroxide (H2O2) whitening treatments.
- Using CT images from five patients, researchers measured the thickness of tooth enamel and the volume of the dental pulp across four groups: lower incisors, upper incisors, canines, and premolars.
- Results showed that thinner teeth, like lower incisors, allowed for more H2O2 diffusion, leading to faster color changes, while thicker teeth like premolars experienced less diffusion and required more treatment sessions for whitening.
