Tooth resorption-Part 2: A clinical classification.

Area of Science:

• Dentistry
• Oral Pathology
• Dental Diagnostics

Background:

• Tooth resorption, involving dentin/cementum loss, lacks a universal classification.
• This absence causes diagnostic confusion and management issues for dental practitioners.
• Resorption can be physiological or pathological, often associated with bone loss.

Purpose of the Study:

• To propose a universal, clinically useful, and clear classification for tooth resorption.
• To combine anatomical, physiological, pathological, and etiological approaches for a comprehensive system.
• To facilitate understanding, diagnosis, and management of tooth resorption globally.

Main Methods:

• Developing a classification system based on anatomical, physiological, and pathological criteria.
• Incorporating etiological factors where relevant for specific resorption types.
• Utilizing simple, relevant, and appropriate terminology for clarity.

Main Results:

• Proposed classification includes two main categories: internal and external tooth resorption.
• Internal resorption is sub-divided into surface, inflammatory, and replacement types.
• External resorption is sub-divided into eight types: surface, inflammatory, replacement, invasive, pressure, orthodontic, physiological, and idiopathic.

Conclusions:

• The proposed classification offers a clear and universal framework for understanding tooth resorption.
• It aims to enhance clinicians' diagnostic accuracy and treatment strategies.
• Universal adoption is recommended to ensure consistency and reduce confusion in dental practice.
