2. The coronal portion of alveolar process seen between teeth

The correct answer is: The coronal portion of alveolar process seen between teeth

Crestal interdental bone refers to the coronal portion of the alveolar process that is located between teeth. It plays a critical role in dental health because it supports the teeth and maintains the architecture of the dental arch. This area is important in procedures such as periodontal assessments, implant placements, and understanding bone loss, which can occur due to periodontal disease. In healthy conditions, the crestal bone forms a stable foundation for the teeth, aiding in their retention and alignment. Understanding the anatomy and location of this specific bone is crucial for dental professionals, as it helps in diagnosing and planning treatment for various dental conditions.
