Dental Assistant Practice Exam

Which of the following is a key indicator of pulpitis?

1. Tooth brushing frequency

2. Uneven gum line

3. Pain or discomfort in the tooth

4. Presence of dental calculus

The correct answer is: Pain or discomfort in the tooth

The key indicator of pulpitis is pain or discomfort in the tooth. Pulpitis refers to the inflammation of the dental pulp, which is the innermost part of the tooth containing nerves and blood vessels. When the pulp becomes inflamed due to decay, trauma, or infection, it leads to sensitivity and significant pain in or around the affected tooth. This pain can be sharp, throbbing, or constant, and may be exacerbated by temperature changes, pressure, or sweet foods. The other options, while related to dental health, do not specifically indicate pulpitis. Tooth brushing frequency is an important aspect of oral hygiene but does not directly correlate with the presence of pulp inflammation. An uneven gum line may suggest periodontal issues but is not symptomatic of pulpitis. The presence of dental calculus indicates poor oral hygiene and can lead to gum disease but does not directly affect the pulp or suggest pulpitis. Therefore, the presence of pain or discomfort in the tooth is the most significant symptom that suggests pulpitis.
