**Core Concept**
The Total-etch concept is a dental adhesive technique that emphasizes the importance of treating the entire surface of the tooth, including both the enamel and the dentin, with a phosphoric acid etchant to create a uniform surface for bonding.

**Why the Correct Answer is Right**
The Total-etch concept was introduced by Buonocore in 1955 as a modification of the acid-etch technique. This concept involves applying a phosphoric acid etchant to the entire tooth surface, rinsing, and then applying a bonding agent. The acid etchant demineralizes the tooth surface, creating micro-retentions for the bonding agent to adhere to. The Total-etch technique is widely used in dentistry for bonding composite resins to teeth.

**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because it doesn't specify the person who introduced the Total-etch concept. While **A** might be a notable figure in dentistry, they are not associated with the Total-etch concept.
**Option B:** This is incorrect because it is a distractor without any basis in fact. The Total-etch concept is a well-documented technique in dentistry, and there is no evidence to support **B** as its originator.
**Option C:** This is incorrect because it is a distractor without any basis in fact. While **C** might be a notable figure in dentistry, they are not associated with the Total-etch concept.

**Clinical Pearl / High-Yield Fact**
The Total-etch concept is a critical step in creating a strong bond between the tooth and the composite resin. It is essential to follow the protocol meticulously to ensure a successful outcome.

**Correct Answer: B. Buonocore.**
