Novel 3-dimensional classification of cervical abrasion using CBCT: A comprehensive analysis

Area of Science:

• Dentistry
• Radiology
• Dental Imaging

Background:

• Tooth cervical abrasion (CA) is a common non-carious lesion that is difficult to diagnose accurately using traditional periapical radiographs.
• Radiographic interpretation is complicated by overlying bone structures and challenges in assessing lesion extent, bone loss, and pulpal involvement.

Purpose of the Study:

• To develop and present a three-dimensional (3D) descriptive classification system for cervical abrasion lesions.
• To utilize Cone Beam Computed Tomography (CBCT) for a comprehensive assessment of CA.

Main Methods:

• A study involving 50 patients with cervical abrasion was conducted.
• CBCT scans (6x6 cm FOV) were acquired, and lesion data were analyzed using 3D imaging software.
• The classification evaluated lesion height (A), buccolingual dimension (B), circumferential spread (C), and remaining dentine thickness (D) using novel scoring criteria.

Main Results:

• CBCT enables a detailed 3D assessment of cervical abrasion lesions.
• The developed classification system provides a reliable and reproducible method for evaluating CA dimensions.
• Key parameters like lesion height, width, spread, and remaining dentine thickness were systematically classified.

Conclusions:

• Cone Beam Computed Tomography (CBCT) is a valuable tool for classifying tooth cervical abrasion in endodontics.
• This 3D classification enhances diagnostic accuracy, treatment planning, and clinical communication.
• The findings support improved patient outcomes and offer new research directions in managing CA.
