Challenges in assessing erosive tooth wear

Area of Science:

• Dentistry
• Dental Public Health
• Epidemiology

Background:

• Assessing erosive wear requires indices that are simple, reproducible, and reflect etiology.
• Differential diagnosis of erosive wear is complex, often co-existing with other tooth wear types.
• Accurate assessment at individual and population levels is challenging without detailed health, diet, and habit history.

Purpose of the Study:

• Describe methodological challenges in assessing erosive wear.
• Critique the strengths and limitations of existing erosion indices.
• Propose the adoption of a validated erosion index for intended use.

Main Methods:

• Literature review of existing erosion indices.
• Analysis of criteria for ideal index properties (simplicity, reproducibility, etiological reflection).
• Discussion of challenges in differential diagnosis and data collection for erosive wear.

Main Results:

• Existing indices often fall short of ideal properties.
• Complexity of erosive wear and co-existing conditions complicate accurate recording.
• Lack of validated indices hinders reliable assessment of prevalence and incidence.

Conclusions:

• Methodological challenges in erosive wear assessment are significant.
• Existing indices have limitations in reproducibility and etiological reflection.
• Adoption of a validated erosion index is crucial for accurate assessment and research.
