Is the epidemiological scoring system for tooth erosion/wear useful?

This summary is based on the article published in the International Dental Journal: An epidemiological scoring system for tooth wear and dental erosive wear (June 2013)


The prevalence and severity of tooth wear and dental erosion is rising in children and there is no consensus about an index to be employed. 

Purpose of the Study

The study aims to assess the reliability of an epidemiological scoring system dental wear index (DWI) to measure tooth wear and dental erosive wear

Key Messages

  • Tooth wear increases with age and males experience it more than females in primary teeth.
  • No significant gender difference of tooth wear in permanent teeth.
  • The epidemiological scoring system could measure tooth and dental erosive wear.
  • The scoring system offers sufficient sensitivity that could be used in monitoring the progression of lesions and in differentiating between the different levels of severity and types of defects.
