Oklahoma Pit and Fissure Sealants State Practice Exam

When preparing a restoration for interproximal decay, which area is usually included in the tooth prep?

1. Only the incisal edges

2. The buccal surface only

3. The occlusal pits and fissures

4. The root surfaces

The correct answer is: The occlusal pits and fissures

The correct answer highlights the importance of addressing the occlusal pits and fissures when preparing a restoration for interproximal decay. In dentistry, interproximal decay typically involves caries that has spread between adjacent teeth, often affecting the surfaces that make contact with one another. The occlusal pits and fissures are critical areas to consider during restoration preparations because they are susceptible to decay accumulation and often play a role in how the restoration will function within the bite. In this context, ensuring that the occlusal pits and fissures are adequately prepared allows for a more thorough removal of carious tissue, ultimately leading to a more effective and stable restoration. It ensures that the restoration can properly seal the tooth and help prevent further decay. The other options suggest areas that would not comprehensively address the nature of interproximal decay. Limiting the preparation to only the incisal edges or the buccal surface would not effectively manage the decay that is likely extending into the interproximal spaces. Focusing purely on the root surfaces, though important in certain contexts, does not apply directly to the restoration needs where interproximal caries is present. Thus, including the occlusal pits and fissures is essential in creating a successful restoration that addresses
