Medical Forum / General / Dentistry / March 2007Sealant
My dentist suggest me to have sealant on my child's back teeth. But I am concerned about negative aspects: such as microleakage that could leave cavities on good tooth and the kind of acid used to etch the chewing surface. Have anyone seen such bad outcomes? > My dentist suggest me to have sealant on my child's back teeth.

I have rarely seen any fail with anything needed more than a conventional 'filling'. Since that is what you were trying to prevent in the first place, and now maybe it is being done on a 12 year-old instead of a 7 year-old (or 18 vs 12, etc.), the restoration itself may very well be of a higher quality (patient behavior is very important to quality of dental treatment). If regular check ups are maintained, a failing sealant can often just be removed and replaced with another sealant. If the grooves are cleaned with sandblasting tool or a laser, and filled with a 'flowable' composite, they are even more predictable.

Have anyone seen such bad outcomes? It can happen, and sometimes leakage under sealants can be hard to detect. Some teeth are more likely to suffer from leakage than others. I think (but cannot swear to ) studies showing this is more likely to happen on premolars than molars. My objection to sealants is also that some dentists will seal every groove and fossa in the back teeth. This is unnecessary and IMO unethical. There should be a demonstrable defect in the surface of the tooth, or this is just pocket padding on the part of the dentist. The virtue here is that with young children you don't have to pick up the drill. My experience is that at some point most of these sealants turn into fillings. However, as Steve Fawks alludes to, sandblasting these defects seems to greatly improve the outcome. Microabrasion actually in effect turns these from sealants into micro-fillings--much more likely to hold up and less likely to leak.

The etchant process is microscopic, so no harm is done. Some pits and fissures of teeth are 0.5 to 1.0 mm deep into the surface of the tooth and are still too narrow for a tooth brush bristle to penetrate. It is impossible to clean plaque out of the entire area. Thus the propensity to decay. With manification and experience, the dentist can be very good at selecting which teeth need sealants. A laser tool for measuring decay (Diagodent) can also be helpful. As has been mentioned, a fast polish and hasty application of 16 sealants is not likely to do much good. Careful selection of susceptable teeth, air abrading the grooves, and bonding flowable composite is very conservative treatment. D Once sealant is applied, does it have to be professionally maintained for the whole life to prevent decay underneath, or it doesn't matter? > Once sealant is applied, does it have to be professionally maintained > for the whole life to prevent decay underneath, or it doesn't matter? It has to be regularly watched for signs it is failing. I rarely if ever see them shed in one piece (this would indicate faulty bonding). Usually failure means there is evidence that decay has started, and at that point a more conventional filling should be placed.

You need not fear damage to the teeth from the procedure. My objection is indiscriminate placement of sealants onto every back tooth whether called for or not. As far as fluoride treatments, one is not a substitute for the other. Sealants are for the defects in the chewing and specific lateral surfaces of the teeth caused during tooth formation in the jaws. Fluoride is more effective in preventing so-called "smooth surface caries) on the sides, gumline, and in between the teeth. For this reason, pit-fissure sealants and fluoride treatments can be seen as complementing each other, rather than one being a substitute for the other.

To >what extent does it hurt teeth? Certainly to a lesser extent than decay does. heh the sealnt method is effective . There is possible to use : glasionomers composites sealant materials. The unique otion and the best is Aegis ACP. Why ? There is not only sealant but treatment material witch realise ACP for self regeneration of first steps of caries. The effect last couple years becouse the matrix realise this active components ONLY when ph drop lower like 5.5 ph So there is 2 kinds of advantages : mechnical prevention active treatment and elimination of frequetly control appointments regards kris-Polanowski DDS >>On Mar 1, 8:49 am, Mark & Steven Bornfeld >><bornfeldm...@dentaltwins.com> wrote: [quoted text clipped - 35 lines] > > Certainly to a lesser extent than decay does. |
