Dental OSCE (Objective Structured Clinical Examination) Practice Exam

What might cause persistent bleeding after a periodontal cleaning appointment?

1. Improper technique during cleaning

2. Retained subgingival plaque

3. Insufficient anesthesia

4. Incompatibility of instruments used

The correct answer is: Retained subgingival plaque

Retained subgingival plaque is a significant factor that can lead to persistent bleeding after a periodontal cleaning appointment. During the cleaning process, it is crucial to remove all sources of plaque and tartar, especially those that are located below the gumline. Failure to completely remove this plaque can maintain inflammation and irritation of the gum tissues, which often results in continued bleeding post-treatment. Plaque that remains can harbor bacteria, leading to an environment conducive to periodontal disease, which exacerbates tissue inflammation and can cause persistent bleeding regardless of the cleaning technique used during the appointment. Effective periodontal therapy should ensure that all subgingival deposits are thoroughly cleaned to promote healing and reduce bleeding. While improper technique, insufficient anesthesia, or instrument incompatibility could potentially contribute to patient discomfort or temporary bleeding, the presence of retained plaque is a direct cause of ongoing issues in the periodontal environment, emphasizing the importance of thorough cleaning and post-treatment patient care.
