Periodontal ligament strain — Clinical Guidelines

Overview

Periodontal ligament strain refers to mechanical stress and potential injury to the ligament supporting teeth, often exacerbated by improper handling techniques during dental procedures or patient repositioning tasks. 1 2

Diagnosis

Clinical assessment focusing on pain, swelling, and mobility of affected teeth.

Radiographic evaluation (X-rays) to assess bone levels and ligament space alterations.

Electromyography (EMG) may help in assessing muscle activity related to strain in specific procedures 3.

Management

Proper ergonomic techniques during dental procedures to minimize strain 1.

Use of assistive devices like sliding sheets for patient repositioning to reduce musculoskeletal load 1.

Physical therapy and ergonomic training for healthcare providers to prevent repetitive strain injuries 2.

Special Populations

Elderly: Increased susceptibility to periodontal ligament strain due to reduced bone density and ligament elasticity; ergonomic patient handling is crucial 1.

Healthcare Providers: Emphasis on ergonomic lifting techniques and use of assistive devices to prevent musculoskeletal disorders 1 2.

Key Recommendations

Utilize sliding sheets and ergonomic assistive devices during patient repositioning tasks to reduce musculoskeletal strain on healthcare personnel (Evidence: Strong 1).

Implement ergonomic training programs for dental practitioners to minimize strain on periodontal ligaments and reduce the risk of musculoskeletal disorders (Evidence: Moderate 1 2).

Monitor and manage repetitive tasks involving forceful pinching or gripping to prevent overuse injuries in healthcare workers, particularly during prolonged procedures (Evidence: Weak 3).
