The importance of children's permanent dentition pit and fissure

The occlusal surfaces of posterior teeth uneven depressed region dental apex locator called pits and fissures of the formation of defects of tooth development in the cusp fusion barriers. The tooth of pit and fissure shapes, shades, is the appropriate place for bacterial growth and reproduction. In this quiet and secluded environment, the bacteria use the sugars in food to multiply and produce acids in the metabolic process, corrosion of teeth, the formation of cavities, therefore, a higher risk of deep pits dental loupes and fissures of suffering from dental caries. At the same time, the bottom of the pit and fissure close to the enamel dentine community or in the dentin caries, damage to the deep rapid development of real and deep large cavities, forming the appearance of small, medically known as such caries pit and fissure caries. Caries can also spread to the pulp last lead to pulpitis or apical inflammation, if not treated will lead to tooth loss. After teeth responsible for the main chewing function, loss of dental articulator masticatory function will be greatly decreased, affect nutritional intake and growth and development.

Studies have shown that our children and young people, posterior pit and fissure caries accounted for 80-90% of the caries, pit and fissure caries can effectively prevent and control occur, can greatly reduce the children and adolescents caries patients disease level, but also reduces the burden of personal economic and social health dental micro motor care resources consumption.

Pit and fissure sealant is no damage to the tooth structure, will be closed material coating on the crown occlusal surface of the buccal-lingual pit and fissure point gap to prevent cariogenic bacteria and acidic metabolites on dental erosion, prevention of fissure caries approach. The principle is that curing the liquid resin into the pit and fissure hardens, forming a protective barrier to cover the pit What are the deformed teeth dental handpiece should do orthodontics and fissure on the outside of cariogenic bacteria can not re-enter, so as to achieve the purpose of the prevention of fissure caries. It's like everyday life, in order to prevent corrosion and infestation of wood products coated with paint, rust, coated with anti-rust paint or spray to prevent iron products. This resin is nontoxic, will not affect the human masticatory function, but also to adapt to the oral buy dental equipment environment.

Pit and fissure sealant is an effective method of prevention of child fissure caries pit and fissure sealants retain the integrity of the tooth surface, can effectively protect our teeth. Pit and Fissure Sealants off, infiltration of resin to enamel suddenly have a protective effect on teeth.
