title: Pronamel and tooth mousse: an initial assessment of erosion prevention in vitro.
abstract: OBJECTIVE
  The aim of this study was to examine whether a single topical application of proenamel or tooth mousse would prevent enamel erosion
  
  
  METHODS
  Enamel samples were treated with either proenamel or tooth mousse applied for 15 min. The control group was placed in distilled water for 15 min. All specimens were then exposed to an erosive challenge of 0.2% citric acid for 1h. Enamel loss was determined using surfometry.
  
  
  RESULTS
  The mean amount of enamel removed in the control group was 5.02 microm (S.D. 1.16). The mean enamel loss in the proenamel group was 2.60 microm (S.D. 0.90) and the mean enamel loss in the tooth mousse group was 3.28 microm (S.D. 1.22). The results for the proenamel group were statistically significantly different from the control group at the p<0.01 level and the results for the tooth mousse group were statistically significantly different from the control group at the p<0.05 level.
  
  
  CONCLUSIONS
  Tooth mousse and proenamel may offer a degree of protection from erosion of permanent enamel.
