Abstract
Aim: The aim of this study is to determine the perception of visual attractivity of rhodium coated brackets by adolescent orthodontic treated patients and their parents or their attendants. Methods: For this study 50 minors (22 male and 28 female) and 50 parents or attendants (17 male and 33 female) were selected at the Orthodontic department of the University Medical Centre Groningen. The participants were shown four pictures of two types of brackets. Both types are identical in shape and size. The first type is coated with a rhodium layer, while the second type is not coated. The participants ranked the visual attractivity of the brackets on a Visual Analogue Scale. A Repeated Measures ANOVA was used for statistical analysis. The significance level was set at α = 0,05. Results: Gender appeared to have no influence on perception of visual attractivity (p < 0,24). Minors rated conventional brackets with an average of 4,95 with a standard deviation of 1,98, with respect to an average of 6,15 with a standard deviation of 1,98 for rhodium coated brackets. Adults rated the conventional brackets averagely on 3,87 with a standard deviation of 1,57. The rhodium coated brackets were rated on an average of 7,04 with a standard deviation of 1,49. The perception of visual attractivity is significantly influenced by the bracket type (p < 0,001). Adults appear to experience greater difference in visual attractivity than minors (p < 0,004). Conclusion: Minors and their parent or attendants gave higher scores to rhodium coated brackets with regard to the visual attractivity in comparison to non-coated brackets. Adults experienced a greater difference between the two types of brackets than minors. Gender appeared to have no influence on the perception of visual attractivity.
