## **Core Concept**
The question pertains to a preventive dental procedure used to protect teeth from decay, particularly in newly erupted teeth. This procedure involves applying a resin material into the fissures of the tooth surface.

## **Why the Correct Answer is Right**
The correct answer, **Buonocore**, is associated with the introduction of the acid-etch technique in dentistry. In 1955, Michael Buonocore introduced the acid-etching technique, which allowed for the bonding of resin materials to enamel surfaces. This innovation enabled the development of fissure sealants, which are used to prevent dental caries by sealing the pits and fissures of teeth.

## **Why Each Wrong Option is Incorrect**
- **Option A:** While there are numerous contributors to dental materials and techniques, the specific introduction of resin application to fissures is attributed to Buonocore's work on acid-etching and bonding.
- **Option B:** Similarly, another figure might have contributed to dental materials or techniques, but they are not credited with introducing the specific application of resin to fissures.
- **Option D:** This option would also be incorrect for similar reasons, as the historical introduction of fissure sealants is tied to Buonocore's innovations.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **fissure sealants** are primarily used on teeth that are at high risk of caries, especially in children and adolescents. The process involves cleaning the tooth surface, applying an acid-etchant, and then placing the sealant material into the fissures. This simple, non-invasive procedure can significantly reduce the incidence of dental caries.

## **Correct Answer:** . Buonocore
