Which animals are commonly used in Class 5 pulp irritation tests?

• A. Dogs
• B. Monkeys
• C. Cats
• D. Rabbits

Answer: (B)

Pulp irritation tests are about how dental pulp tissue responds to a material placed in the tooth. To get results that best predict what would happen in humans, the animal model needs pulp tissue that behaves similarly to human pulp. Non-human primates, such as monkeys, have dental pulp with a very comparable cellular make-up, blood supply, and healing/inflammatory patterns to humans. This similarity makes monkeys the most appropriate model for Class 5 pulp irritation testing, because the observed tissue reactions are more likely to mirror human responses than those seen in other animals. Other species like dogs, cats, and rabbits have been used in various dental material studies, but they don’t replicate human pulp responses as closely for this specific test, so they aren’t the standard model here. It’s also worth noting that ethical considerations increasingly push researchers toward alternatives and in vitro methods, but historically monkeys were favored for this kind of pulp irritation assessment due to their closer resemblance to human dental pulp.
