This prospective study aimed to evaluate effects of surgically assisted rapid maxillary expansion (SARME) on the color, maxillary anterior teeth by comparing them with untreated control group.

In this study fifteen patients who underwent SARME and fifteen untreated control patients were included. Color measurements of the six maxillary anterior teeth were performed using a spectrophotometer. Periodontal health was assessed using the Gingival Index(GI), Probing Depth(PD), Plaque Index(PI), while pulp sensitivity was evaluated using an electric pulp tester(EPT). Color changes were calculated and fractal analysis was performed on CBCT images obtained evaluate the trabecular bone structure adjacent to the maxillary central incisors.
