Answer 8

mandibular molars

Question 9

what has higher retention rate premolars or molars

Answer 9

premolars

Question 10

bonding sealants improve retention how

Answer 10

helps wet the fissure
improves sealants penetration into fissure
increase bond strength
improve the clinical retention of the sealants
