--Subject: sealant retentionThis is worth looking at. SeLECT Defense sealants delivers an anti-microbial in the form of a selenium resin based compound. You can be rest assured that there is no trapping undetected decay, as biolfilms cannot live under them. In a split mouth, double blind clinical trial completed in September of 2011, 120 patients showed a 96% retention rate on fully erupted molars versus another big player with a marginal 81% retention. Not only that, we showed ZERO plaque growth whereas the other brand showed 12%. Please message me personally if you would like a copy of the study. ashley@e34tech.com

Has any one seen a recent study that reported a 44% retention rate for glass ionomer sealants and a 40% retention rate for resin on newly erupted molars after one year?Jane Gillette, DDSOngoing public health group discussion on sealants.If the stuff's so strong, how cytotoxic is it elsewhere in the kid? Other effects like the xenoestrogenics?In any event, my contention's always been that sealant 'retention' is not relevant. First of all, they often LOOK like they're there but leak like a sieve, and second of all, the important thing is preventing tooth decay and loss WITHOUT, in the process, damaging the teeth's owners.More commentary below.Finally, in terms of oralsystemics, AAOSH needs to start paying attention to the effects of the compounds dentists are using on their patients and not just to diseases of the mouth affecting the rest of the body.regardsbill domb
Pertinent to Dr. Macintyre's comments, a recent article in JADA (Antonson SA et al, JADA 143(2): 115-122) addresses some of these issues. The 24 month study looks at retention, marginal staining and cariostatic properties of both GI sealant and Resin-based sealants. While retention rates were both similar at 44% and 40% respectively, more important was the caries development. No GI sealants showed demineralization with sealant loss, whereas resin-based did show demineralization where sealants were lost.
This study highlights the value of early intervention with glass ionomer sealant on the partially erupted permanent first molars in high risk children. The retention problems will always be with us given the added difficulty of treating these teeth with limited access and saliva control. It does suggest that the two-stage treatment of these teeth is highly likely for most of them; however, the treatment outcomes in terms of loss of tooth structure due to caries and restoration when we simply wait for full eruption and access make this treatment approach worthy for consideration in at risk children.
