Main Goal

To advance scientific knowledge on the etiology, pathogenesis, diagnosis, clinical management and prevention of dental erosion and dental abrasion.

Specific Goals

  • To develop and validate models for studying dental erosion and abrasion and their prevention

  • To develop and validate new clinical methods for measuring the progress of dental erosion and abrasion

  • To develop and evaluate approaches to decrease the erosive potential of foods and beverages

  • To develop and evaluate new methods to clinically manage and prevent dental erosion and abrasion
