Why are caries susceptible to fissures?
Pits and fissures of the occlusal surfaces of the posterior teeth are more prone to caries development than the smooth surfaces due to their morphological complexity, making dental hygiene more challenging leading to increased plaque accumulation [1].
Why are pits and fissures more susceptible to smooth surfaces?
Which statement describes why pits and fissures are more susceptible to decay than smooth surfaces? They do not benefit from the effects of fluoride. The enamel at the base of fissures is thinner. Saliva cannot clean deep pits and fissures.
Why dentin in pit and fissure caries is easily affected than smooth surface caries?
Dentin and cementum are more susceptible to caries than enamel because they have lower mineral content. Thus, when root surfaces of teeth are exposed from gingival recession or periodontal disease, caries can develop more readily.
What causes pit and fissure caries?
Pit and fissure cavities occur on the chewing surface of your teeth. Not cleaning your teeth well, frequent snacking and sipping sugary drinks are the main culprits behind cavities. Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes.
Which is a contraindication to receive pit and fissure sealants?
Contraindications to sealants do occur. They include a patient’s behavior management preventing proper sealant placement, inability to isolate and maintain a dry field, semi-erupted teeth, presence of decay and an allergy to methacrylate.
Which type of fissure are not caries susceptible?
(1) Shallow and wide ‘V’ or ‘U’ shaped fissures. (2) Deep and narrow ‘I’ or ‘K’ shaped fissures. The V/U shaped fissures are self-cleansing and somewhat caries resistant. The I/K shaped fissures are caries susceptible and may have branches to increase complexity.
Where do pit and fissure caries first occur?
Dental caries can readily begin on biting surfaces of posterior teeth, in pits, fissures, and defects of the enamel. The enamel at the base of pits and fissures is frequently thin.
What tooth surfaces are most susceptible to the development of dental caries?
Individual tooth surfaces have vastly different susceptibilities to caries, with the pit and fissure (occlusal) surfaces the most susceptible, and the smooth (labial and lingual) surfaces the least susceptible. The most frequent sites of attack are the occlusal surfaces of the first and second permanent molars.
Which teeth are the most vulnerable to pit and fissure caries?
Which tooth is more susceptible to caries?
In examined caries teeth, the molars were the most significantly affected at 45%. Regarding the distribution of caries within individual teeth, the first and second maxillary molars were most susceptible to caries at 11.5%, while the mandibular central incisors were least susceptible, at 1.7%.
Do pit and fissure sealants prevent dental caries?
Dental Sealants are accepted as an effective preventive method for Dental Caries, and as long as the sealant remains adhered to the tooth, cavities can be prevented. The ability of a pit and fissure sealant to prevent dental caries is highly dependent on its ability to retain on the tooth surface.
What happens if you don’t treat your pits and fissures?
Pits and fissures if left untreated will lead to pain, loss of tooth and infection. Due to their inability to be cleaned, they grow rapidly and are one of the leading causes of cavities. Pits and fissures have the capacity to spread rapidly due to which it is always advisable to treat it as soon as it is diagnosed.
What is the purpose of fissures and pits in the food?
As the Pits are Fissures are a magnet to food debris which lead to bacterial colonization and thus leads to caries. As these grooves are blocked with a Sealant they prevent debris accumulation and thus decrease the risk of cavity formation.
How to prevent dental caries in occlusal surface?
Occlusal surface of young patients have high caries susceptibility due to presence of pronounced cusps and Grooves, pits and fissures. Fluoride which is said to prevent dental caries is usually ineffective in occlusal surface, it is very effective on smooth surfaces of the tooth like Buccal, Lingual and interdental surfaces.
