Tooth with acute pulpitis will give response to electric pulp tester?
**Core Concept**
Tooth with acute pulpitis exhibits an altered response to electrical stimuli due to inflammation and damage to the dental pulp. The pulp contains nerve fibers that transmit pain signals, and acute pulpitis disrupts normal pulp physiology.
**Why the Correct Answer is Right**
In acute pulpitis, the pulp tissue becomes inflamed, leading to the release of chemical mediators that sensitize the nerve fibers. This sensitization results in an exaggerated response to stimuli, including electric pulp testing. The inflamed pulp also produces prostaglandins, which increase blood flow and further exacerbate the response to electrical stimuli. The altered response to electric pulp testing is a hallmark of acute pulpitis.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because chronic pulpitis typically results in a decreased response to electric pulp testing due to pulp degeneration and nerve fiber damage.
**Option B:** Incorrect because a tooth with a healthy pulp will respond normally to electric pulp testing, without the exaggerated response seen in acute pulpitis.
**Option C:** Incorrect because a tooth with a necrotic pulp will not respond at all to electric pulp testing due to the absence of viable nerve fibers.
**Clinical Pearl / High-Yield Fact**
Acute pulpitis can be distinguished from chronic pulpitis by an exaggerated response to electric pulp testing. Remember that acute pulpitis is a medical emergency requiring prompt treatment to prevent further pulp damage.
**Correct Answer: B. A tooth with a healthy pulp will respond normally to electric pulp testing.**
