The spelling of "Pit Fissure Sealants" in English follows the regular rules of phonetics. It is pronounced /pɪtˈfɪʃər ˈsiːlənts/. The word comprises of two distinct parts - "Pit Fissure" and "Sealants". The first part refers to the anatomical features of teeth that are susceptible to decay, while the second part represents the material used to seal the pits and fissures of the teeth to prevent tooth decay. The correct spelling is important to ensure proper communication within the dental profession.
Pit fissure sealants are dental materials used to prevent dental caries, also known as tooth decay, specifically in the grooves and pits present on the chewing surfaces of molars and premolars. These pits and fissures can be difficult to clean with regular brushing, making them vulnerable to the accumulation of plaque and bacteria.
Pit fissure sealants are typically made of a resin material, usually composite or glass ionomer, that is applied as a liquid onto the tooth surface. The material then hardens or polymerizes to form a protective coating over the pits and fissures. This coating creates a smooth, easy-to-clean surface that helps to prevent the accumulation of food particles and bacteria, reducing the risk of tooth decay.
The process of applying pit fissure sealants is relatively simple and painless. The tooth surface is thoroughly cleaned and dried, and an acid etchant may be used to roughen the surface for better adhesion. The sealant material is then flowed into the pits and fissures and cured using a specialized light to bond it to the tooth surface.
Pit fissure sealants are most commonly used in children and teenagers as a preventive measure against tooth decay. However, they can also be used in adults with deep grooves and a high susceptibility to tooth decay. Regular check-ups with a dentist are necessary to monitor the condition of the sealants and determine if any repairs or replacements are needed.
