Answer :
Final answer:
Proficiency in dental radiography is not necessary for a dental assistant applying pit and fissure sealants, while knowledge of dental anatomy, understanding of dental materials, and familiarity with dental office procedures are required. The correct answer is 3) Proficiency in dental radiography
Explanation:
The qualification that is not required for a dental assistant who applies pit and fissure sealants is proficiency in dental radiography. While knowledge of dental anatomy, understanding of dental materials, and familiarity with dental office procedures are all relevant to the application of sealants, the ability to perform dental radiographs is not directly connected to this particular task. Pit and fissure sealants are protective coatings applied to the chewing surfaces of teeth to prevent cavities.
