Filled sealants with high spots after placement can be worn down with occlusal wear.
  1. True
  2. False
Explanation
Answer: B - It is not true that filled sealants with high spots after placement can be worn down with occlusal wear.
The filler content in a sealant makes it harder than surrounding natural tooth surfaces. An unevenly placed filled sealant which interrupts normal occlusion can only be adjusted with a dental drill.
