what do you think about placing sealants at health fairs when there is NO followup,poor isolation, and poor clinical skill? is this below the standard of care? how do you gaurentee that the sealants won't leak and actually INCREASE the risk of decay?

The first time that I placed a sealant on an adult, I noticed that I put too much sealant (even though I used a microbrush). The patient complained, of course. When I did it on a pediatric patient though, she did not complain at all. I was more careful the second time around, but how is it that children are "more adaptable" to the high occlusion that will bug an adult patient so much?

Since the oral sealant is a layer of plastic that covers the O surface of tooth. Doesn't it make it hard sometimes for dentists to clinically determine if there are existance of caries underneath the sealant? Sometimes we can see peripheral dark stains, how about then there are not enough radiographic evidence of possible caries under the sealant? Should we wait and see or open it up?

Is it worth placing rubber dam on a pedo patient for sealants??? (Since rubber dam usually means need for anesthesia which encompasses more distress to the pedo patient.)
This is a response to the post by student #122. I feel that one must consider the population treated at health fairs. In my experience almost entirely latin children who may rarely if even get to a dentist. In other words a population that would benefit the most from preventive measures. If isolation is poor during a sealant it will immediately come off with an explorer. If it is high in occlusion it will very quickly wear or fracture, hopefully leaving some of the pits and fissures sealed. In the end it would be difficult to cause long-term harm and very likely to lower the rate of caries in kids.

I don't think that putting sealants on can ever INCREASE the risk of decay, because even if the sealants were to leak, they wouldn't provide a valley of tooth structure much like a deep fissure, but instead a valley of sealant material (which can't decay due to bacteria). When looking at the statistics of how many caries and teeth that sealants have protected and their efficacy in reducing caries in teeth with deep fissures and pits, I'm sure it outweighs the number of caries it has caused through leakage etc...
