INBDE (Integrated National Board Dental Examination) Practice Exam

The initial lesion of gingivitis occurs within how many days?

1. 2-4 days

2. 5-7 days

3. 1-2 days

4. 8-10 days

The correct answer is: 2-4 days

Gingivitis is a form of gum disease that is characterized by inflammation of the gums. The initial lesion, or the first sign of disease, can occur within 2-4 days after bacteria and plaque build up on the teeth and gums. This initial lesion is usually painless and may not be noticeable to the person experiencing it. Waiting longer than 4 days to seek treatment can lead to further damage and more severe symptoms. Option B (5-7 days) is incorrect because it is outside of the typical time frame for the initial lesion to occur. Option C (1-2 days) is incorrect because it is too soon for the initial lesion to occur and is not a common timeframe. Option D (8-10 days) is incorrect because it is too late for the initial lesion to occur and suggests that the disease has progressed significantly.
