Abstract
A study was carried out to establish the relative need for treatment of a range of defects of dental appearance and identify differences between individual and group assessments. Three groups (n = 42), two of patients (one referred for a defect of dental appearance and one not) and one of dental students, assessed urgency of need on a visual analogue scale (VAS), of four cases of dental defect presented as colour prints. All groups rated the need for treatment of the four cases in the same order. Data sets were non-normal with wide ranges. Patients without a defect of appearance usually assessed treatment need as significantly less urgent. Marked variation was discovered between individual assessments within otherwise similar groups. Based on group decisions, guidelines for treatment of defects of dental appearance could be established. However, so extreme are individual variations that very sympathetic application would be needed if dissatisfaction is not to result.
