What are the three types of pulpal stimuli?

1. Physical, Chemical, Biological

2. Thermal, Mechanical, Biological

3. Physical, Mechanical, Biological

4. Mechanical, Biological, Chemical

The correct answer is: Physical, Mechanical, Biological

The three types of pulpal stimuli are correctly identified as physical, mechanical, and biological. To understand this, consider that pulpal stimuli refer to the various forms of irritants or influences that can affect the dental pulp, leading to responses such as pain or sensitivity. Physical stimuli encompass actions such as temperature changes, which can induce reactions from the pulp. Mechanical stimuli involve forces applied to the teeth, such as chewing or grinding, which can put stress on the pulp. Biological stimuli typically relate to the presence of bacteria or other microbial agents that can cause inflammation or infection within the pulp. This classification helps in diagnosing issues related to pulp sensitivity and can guide treatment approaches in dentistry, ensuring that dental professionals address the underlying causes of pulp-related discomfort effectively.
