Success of pit & fissure sealants is affected mainly by:
- a. increased time of etching.
- b. contamination of oral saliva***
- c. salivary flow rate.
- d. proper fissure sealant.
The correct answer is (b) contamination of oral saliva.
Pit and fissure sealants are a preventive dental treatment that can help protect teeth from decay. They are applied to the chewing surfaces of teeth, where they form a protective barrier over the pits and fissures, which are the deep grooves that are more likely to trap food and bacteria.
Factors for success of pit and fissure sealants:
The success of pit and fissure sealants is affected by several factors, including:
- Contamination of oral saliva:
Oral saliva contains bacteria and other substances that can interfere with the bonding of the sealant to the tooth. If the sealant is contaminated, it is more likely to come off, which will leave the tooth unprotected from decay.
- Proper fissure sealant:
The sealant must be properly applied to the tooth in order to be effective. This means that the sealant must be thick enough, that it must be applied to all of the pits and fissures, and that it must be allowed to bond to the tooth properly.
- Increased time of etching:
Etching is the process of roughening the surface of the tooth to help the sealant bond to it. Increased time of etching can help to improve the bond between the sealant and the tooth.
- Salivary flow rate:
Salivary flow rate can also affect the success of pit and fissure sealants. If the salivary flow rate is high, the sealant may be washed away before it has a chance to bond to the tooth.
Therefore, the most important factor affecting the success of pit and fissure sealants is contamination of oral saliva.
