Summary

Tooth wear, encompassing abrasion, attrition, and erosion, is a growing dental concern. Understanding the fundamental wear processes is crucial for diagnosis and prevention, as they affect both natural teeth and restorative materials.

Area of Science:

  • Dentistry
  • Biomaterials Science

Background:

  • Tooth wear is a prevalent and escalating issue in dental practice.
  • Traditional classifications include abrasion, attrition, and erosion, but most cases involve multiple processes.
  • Understanding the fundamental mechanisms of wear is essential for effective management.

Purpose of the Study:

  • To emphasize the importance of understanding fundamental tooth wear processes.
  • To highlight the limitations of traditional categorization in complex clinical scenarios.
  • To underscore the impact of wear on both natural dentition and restorative materials.

Main Methods:

  • Review of established dental literature on tooth wear.
  • Analysis of the etiological factors contributing to tooth wear.
  • Discussion of diagnostic approaches focusing on fundamental wear mechanisms.

Main Results:

  • Most clinical tooth wear cases result from a combination of abrasion, attrition, and erosion.
  • Wear mechanisms include direct surface contact, abrasive slurries, and corrosive environments.
  • Tooth wear processes affect restorative materials similarly to natural tooth structure.

Conclusions:

  • Diagnosing tooth wear by identifying fundamental processes is more practical than strict categorization.
  • Preventive strategies must consider the diverse causes and timing of wear (e.g., mastication, nocturnal bruxism).
  • A thorough understanding of wear mechanisms is paramount for successful diagnosis, prevention, and treatment planning in restorative dentistry.
