Summary

This summary is machine-generated.

Tooth flexure from non-axial occlusal forces causes cervical lesions, leading to enamel and dentin cracks. These abfraction lesions increase bacterial plaque retention and dental hypersensitivity.

Keywords:

Cervical lesions abfraction dental abrasion occlusal trauma

Area of Science:

Dentistry
Biomechanical Engineering

Background:

The abfraction theory explains tooth structure loss due to occlusal forces.
Non-axial forces cause tooth flexion, leading to cervical defects.

Observation:

This study examined 102 participants (54% male, 46% female, aged 20-80).
Participants were from urban (76%) and rural (24%) areas.
Data collected from August 2018 to August 2019.

Findings:

Abfraction lesions initiate as enamel and dentin cracks in the cervical area.
These defects facilitate bacterial plaque accumulation.
Lesions contribute to dental hypersensitivity and potential pulp vitality issues.

Implications:

Understanding abfraction mechanics is crucial for diagnosing and managing cervical tooth wear.
This research highlights the role of occlusal stress in dental pathology.
Further investigation into preventive strategies for abfraction lesions is warranted.
