Which grading indicates a gingival enlargement that covers three-quarters or more of the crown?

The grading that indicates a gingival enlargement covering three-quarters or more of the crown is Grade 3. In periodontal assessments, grades of gingival enlargement are established to help clinicians evaluate the extent of the condition effectively.

Grade 3 signifies a severe level of gingival overgrowth, where the enlargement impacts a significant portion of the tooth's surface, specifically three-quarters or more of the crown. This level of enlargement can severely hinder oral hygiene practices, cause aesthetic concerns, and may lead to periodontal complications if not managed appropriately.

Understanding the grading system is crucial for diagnosing and developing treatment plans for patients. Lower grades correspond to lesser degrees of enlargement and less severe implications for overall dental health. In a clinical setting, recognizing the extent of gingival enlargement helps to determine the necessary interventions for care.
