Descriptive Analysis of Factors Associated with External Cervical Resorption

Area of Science:

• Dentistry
• Oral Pathology
• Radiology

Background:

• External cervical resorption (ECR) is a complex dental condition.
• Understanding its prevalence and associated factors is crucial for diagnosis and treatment.

Purpose of the Study:

• To analyze the occurrence of external cervical resorption (ECR).
• To investigate the relationship between ECR and patient characteristics (sex, age, tooth type).
• To identify potential predisposing factors contributing to ECR.

Main Methods:

• A descriptive analysis of 337 teeth with ECR from 284 patients was conducted.
• Data were collected from university hospitals in Belgium and the Netherlands (2010-2015).
• Methods included clinical and radiographic examinations (periapical radiography, CBCT) and literature review for predisposing factors.

Main Results:

• ECR occurred in 54% of male and 46% of female patients, showing no sex predilection.
• Maxillary central incisors were most affected (29%), followed by canines and molars.
• Common predisposing factors included orthodontics (45.7%), trauma (28.5%), and poor oral health (22.9%).

Conclusions:

• ECR is not significantly related to patient sex.
• The condition is often multifactorial, with orthodontics, trauma, and poor oral health being key contributors.
• Identifying these factors aids in early ECR diagnosis.
