Restorative treatment need assessment by dentally and nondentally trained subjects

A study was carried out which compared how two groups of people, one with clinical dental experience and one without, assessed restorative dental treatment need. Using a visual analogue scale, a group of final year dental students ( n = 50) and nonclinical university students ( n = 50) assessed the extent to which they considered common dental imperfections, viz. spacing of the upper anterior teeth and discolouration of upper anterior teeth, warranted restorative correction. The group of dental students judged the necessity for treatment of discolouration to be more urgent than correction of spacing. The nondental group did not differentiate between the degrees of need. Data were non‐normal in distribution but the use of appropriate statistical tests showed the differences in mean assessments to be significant.
