Subjective and objective perception of upper incisors.
The purpose of this study was to evaluate the subjective judgment (SJ) of patients on their own dental appearance and to correlate the results with objective measurements (OM) of their dentition concerning the appearance of the upper incisors. Seventy-five participants (30 men and 45 women) with normal well-being were included in the study. In a questionnaire they judged the appearance of their upper incisors. Furthermore, OM were evaluated by the investigator with regard to the following points: (i) absolute length of the upper central incisors, (ii) their length exposed during laughing, (iii) width-to-length ratio of central incisors and (iv) the proportion between the width of the lateral and central incisors. The subjective results were registered on visual-analogue scales. For the objective results standardized photographs were taken. No gender dependent differences could be found for the objectively measured parameters (median): OM1, 10.7 mm; OM2, 8.1 mm; OM3, 0.81; OM4, 0.79. However, significant correlations between subjective and objective results (SJ1/OM1, SJ2/OM2, SJ3/OM3) could be shown for men, but not for women. The maximum of the calculated regression-curves for men reflect 'golden standard values' well known from the literature. The degree of satisfaction concerning appearance of anterior incisors in accordance with golden standard values is higher for men than for women.
