Fossa sealing is adapted to all caries-prone permanent molars, milk molars and school-age children with abnormal tooth development and the presence of morphological malformations. The treatment involves the use of special sealing materials to fill the grooves on the tooth surface, thus reducing the incidence of caries.
Fossa sealing is a non-invasive operation, usually performed during the growth and development stage of children’s teeth, and is a technique that aims to increase the resistance of children’s teeth to caries. It is mainly applied to all permanent and milk molars that are susceptible to caries, or to children with abnormal tooth development and the presence of malocclusion.
The treatment of fossa sealing includes cleaning the fossa and sealing the fossa.
First, the surface of the teeth is cleaned of soft scale and food debris to make sure that the sockets are free of caries, and then the sockets are closed. The surface of the tooth is treated with an appropriate amount of acid etching agent, and then a special sealant, such as resin, is used to fill the fossa on the surface of the tooth, blocking food debris, plaque and other substances from the outside world, thus reducing caries.
It is recommended that children undergo fossa sealing as early as possible after tooth eruption, which can effectively prevent the occurrence of fossa caries.
