Preventative (noninvasive)Dental sealants are highly effective in preventing dental caries in the pit and fissure areas of the teeth. Dental sealants are made of a resin material, and are applied to the pits and fissures of teeth to prevent dental caries. A dental sealant is successful onlyif it firmly adheres to the enamel surface, and protects the pits
Sealants are part of a Preventive ProgramFluorideFlossingTooth BrushingDiet-Nutrition planPatient EducationDental VisitsUnfortunately lack of public awareness and access inhibits patients from rec. P/F Sealants.
Pits and fissures are the fossa and grooves that failed to fuse during development. Bacteria accumulate in the narrow pits and fissures.Even a single toothbrush bristle is too large to enter and clean pits and fissures.
The sealant acts as a physical barrier.Dental sealants are a noninvasive technique that preserves the tooth structure and at the same time prevents dental decay.Goal of Dental Sealants
Sealants and Existing CariesDuring sealant placement, some bacteria will be trapped beneath the sealants.Some teeth with very small initial carious lesions may be inadvertently sealed.Numerous studies have shown that neither of these will increase the chance of caries development or caries growing beneath the sealant. Several studies have shown that the number of bacteria in small, existing carious lesions that had been sealed decreased dramatically with time.
The sealant acts as a physical barrier and can prevent tooth decay in the most common area in the tooth called the central groove. Goal of Dental Sealants
Indications for Dental SealantsPit and fissure sealants are especially useful for selected patients through the caries-active period (ages 6 to 15 years). Sealants are indicated for teeth withDeep pits and fissuresPreferably in recently erupted teeth (less than 4 years) Sealants should be used as part of a preventive program that includes the use of fluorides, dietary considerations, plaque control, and regular dental examinations.
BacteriaEarliest sign of tooth decay is a white spot.If the sealant is done correctly, bacteria will not reemerge because bacteria needs a supply of carbohydrates as a nutrient supply.
