What is a pit and fissure sealant? - ANS A resin material that is introduced into the occlusal pit and fissures of caries- susceptible teeth for the purpose of acting as a physical protective barrier against caries- producing bacteria. What is the purpose to pit and fissure sealants? - ANS physical protective barrier against caries- producing bacteria Why are pits and fissures more susceptible to caries than the smooth tooth surface? - ANS Fluoride is not nearly as ...

According to the Cochrane Database of Systematic Review, what is the one-year reduction in caries following properly placed dental sealants? - ANS 86% How does the cost of placing a dental sealant compare to the cost of placing an occlusal amalgam restoration? - ANS restoration costs twice as much as a sealant The need for placement of dental sealants has become more of a necessity because: - ANS disease trends indicate majority of caries are occlusal Which of fo...

Which of the following tooth surfaces are most prone to dental caries in school-age children? A. Occlusal surfaces of maxillary first premolars B. Occlusal surfaces of mandibular premolars C. Occlusal surfaces of mandibular first molars D. Lingual surfaces of maxillary anterior teeth - ANS C.
