What accumulates in the narrow pits & fissures if no sealant has been placed?

• A. Debris
• B. Bacteria
• C. Stains
• D. Saliva

Answer: (B)

The main idea is that pits and fissures, if not sealed, become havens for bacterial plaque. These narrow grooves trap food particles and provide a protected environment where bacteria can adhere and multiply, leading to accumulation of bacteria there. While debris or stains can be present, the defining buildup in unsealed fissures is bacteria, which is why sealing these areas helps prevent early caries. Saliva is continuously present and does not accumulate specifically in the grooves.
