a
Undergraduate dental students (N=21) were asked to smell each other's whole mouth malodor
and to rate each score in a blind fashion, on a semi-integer scale of 0-5, with two minute
pauses between measurements (Rosenberg et al., 1991b).
Pearson linear regression analysis was carried out comparing each student's set of
valuations with the mean class scores.
b
Scores (N=21) were concomitantly carried out by an experienced judge of oral malodor (MR).
