Is diagnosing exposed dentine a suitable tool for grading erosive loss?

Area of Science:

• Dentistry
• Dental Erosion
• Tooth Wear

Background:

• Quantifying tooth wear, especially erosion, often relies on differentiating enamel-only lesions from those reaching dentine.
• Higher scores in grading systems signify exposed dentine, indicating advanced stages of tooth wear or erosion.
• Clinical diagnosis of exposed dentine typically involves evaluating changes in tooth color or optical properties.

Purpose of the Study:

• To critically review and discuss the challenges associated with current methods for quantifying tooth wear and erosion.
• To examine the limitations of classifying erosion severity based on exposed dentine area or depth.
• To highlight the need for further research into the prognostic significance of exposed dentine.

Main Methods:

• Literature review of existing grading systems for tooth wear and erosion.
• Critical analysis of diagnostic criteria for exposed dentine.
• Discussion of the relationship between enamel thickness, exposed dentine area, and actual tissue loss.

Main Results:

• Classifying erosion severity by exposed dentine area or depth is difficult and poorly reproducible.
• The extent of tissue loss is not always directly correlated with the area of exposed dentine, considering enamel thickness variations.
• There is limited longitudinal data on the prognostic value of exposed dentine in tooth wear and erosion.

Conclusions:

• Current grading procedures for tooth erosion based on exposed dentine have significant limitations.
• The diagnostic approach relying on exposed dentine lacks reproducibility and may not accurately reflect the severity of tissue loss.
• Further research and reevaluation of current grading systems are essential to improve the assessment and prognosis of tooth wear and erosion.
