Document Summary
Lecture #1 - sealants: explain the importance of sealants in dental caries prevention, 88% of dental caries occurred in pit-and-fissure surfaces among us school as long as it"s completely sealed. children (1988-91). 50% after 5 years: 15 year study on permanent first molars 27% complete retention, 35% partial retention. Sealant is effective as long as there"s complete retention, however, as retention decreases, effective decreases, and caries/restoration rate increases: effects of enamel conditioning on retention. Increases surface wettability and binding between sealant/substrate by removing contaminants: produces modified outer surface that"s better for retention, produces irregularities that allow sealant penetration. No, patients not at risk from sealant bpa: is. 2008: place on primary and permanent teeth if elevated risk for all ages, should place over non-cavitated lesions for all ages. Resin-based top choice, glass ionomer cement if there"s a concern about moisture: school-based sealant programs, 2009, target high-risk communities and individuals (those least likely to see and sound dentist)
