Results: The mean score was highest for IB, followed by EE, DB, CB, CwB and OB. Oneway ANOVA with Bonferroni post hoc test showed no difference between the highestscoring occlusion types (IB and EE, p > 0.99); each of the remaining groups was significantly different from both IB and EE (p < 0.001). The scores for DB, CB, CwB and OB were progressively lower, although not significantly different from one another (p > 0.05). Univariate ANOVA to determine the effects of evaluator characteristics (age, level of education, gender and interaction between level of education and gender) showed that gender was a significant factor (p < 0.034) for all bite groups except OB. Level of education was significant only for OB (p = 0.020) and age only for EE (p = 0.011). The interaction between level of education and gender was significant for all bite types (p < 0.046).

Conclusions: Lay evaluators identified ideal and EE bite occlusal relationships as esthetically most pleasing. They judged DB, CB, CwB and OB bite relationships as less esthetically pleasing but did not differentiate between these types of malocclusions.
