Final Answer:
Air abrasion is sometimes used before sealant application to open fissures and remove slight decay. Option B is the answer.
Step-by-step explanation:
In dental procedures, preparing the tooth surface is crucial before applying sealants, especially when addressing fissures and slight decay. Option B, "Air abrasion," involves using a focused stream of abrasive particles propelled by compressed air to gently remove decayed or damaged tooth structure. This technique is particularly useful in preparing the tooth for sealant application, ensuring better adhesion and sealing effectiveness.
Dental anesthesia (Option A) is used for pain management, fluoride treatment (Option C) is typically applied to prevent tooth decay, and radiographic imaging (Option D) is used for diagnostic purposes, none of which directly address the preparatory needs for sealant application.
Option B is the answer.
