Dental Admissions Test (DAT) Practice Test

The dental explorer is a specialized instrument used primarily for diagnosing cavities and other irregularities in teeth. Its design features a thin, pointed tip that allows the dentist or hygienist to gently explore the surface of the teeth, checking for soft areas that may indicate decay. The sharp point can also help detect pits and fissures where cavities are likely to form.

While other instruments mentioned have their own specific purposes, they do not serve the primary role of diagnosing cavities. The dental mirror is essential for visualizing the oral cavity and enhancing illumination but does not probe for decay. The probe is often used similarly to the explorer but typically refers to a general tool without the specific dental context. A scaler is utilized for removing calculus and plaque from teeth surfaces and is not designed to diagnose cavities. Thus, the dental explorer is the most suitable choice for the purpose of cavity diagnosis.
