Abstract :Aim: This study aimed to determine the effects of toothbrushing force on the surface roughness, gloss, and color change of dental enamel. Material and Methods: This study was carried out on the sound vestibular enamel surfaces of 16 human permanent incisors extracted for periodontal or orthodontic reasons. Teeth were randomly divided into 2 subgroups (n=8, per group) and embedded in acrylic blocks. The vestibular enamel\'s initial surface roughness, gloss, and color were measured. Three measurements per sample were performed and averaged. Six months of toothbrush simulation with 5,000 circular cycles (with a load of 1.5 and 2.5 N for groups 1 and 2, respectively) (MOD Dental, Turkey) was performed. The same measurements were repeated and the data were analyzed with independent samples and paired sample t-tests (p<0.05). Results: A significant difference was observed between the surface roughness values after the toothbrushing simulation with 1.5 and 2.5 N (p=0.022). Surface gloss values decreased significantly when 1.5 and 2.5 N forces were applied (p=0.001, p=0.002, respectively). Color change (ΔE) for brushing force of 2.5 N (3.48±0.83) was statistically significantly higher than 1.5 N (2.42±0.86), (p=0.025). Conclusion: Results of this study revealed that the surface roughness and color change values increased depending on the applied brushing force whereas gloss values decreased.
