IMPACTION OF DENTAL MIDLINE DEVIATION TO ESTHETIC SMILE
Main Article Content
Abstract
This cross- section study aims to evaluate the threshold of lay people’s esthetic perception of dentition midline deviation. The dental midline of an esthetic smile photo was altered digitaly to shift to the left and right from 1 to 4mm. The images then were evaluated by 50 lay persons to determine the threshold for acceptable midline deviation and factors influencing perception. Results: The mean value for the threshold above which a deviation was judged ‘‘unesthetic smile’’ was 2,98 ± 0,78mm. Man and woman perception are 3,02 ± 0,8mm and 2,94 ± 0,79mm respectively. There was no statistically difference (p > 0.05) between man and woman perception.
