What is the purpose of dental sealants quizlet?
What is the purpose of dental sealants? To prevent dental caries in the pits and fissures.
What is dental sealant and how it is used?
Dental sealants are thin coatings that when painted on the chewing surfaces of the back teeth (molars) can prevent cavities (tooth decay) for many years. Sealants protect the chewing surfaces from cavities by covering them with a protective shield that blocks out germs and food.
Which type of sealant may require an occlusal adjustment?
The filled sealants usually require occlusal adjustments, which lengthen the procedure unnecessarily. The unfilled resin sealants on the other hand have a lower viscosity and provide greater penetration into fissures and better retention [23,26].
What is the main cause of sealant failures quizlet?
The primary cause of sealant retention failure is moisture contamination.
What can sealant materials harden?

| why is clear sealant material less desirable | it is more difficult to evaluate |
| what is the difference between filled and unfilled sealants | filled sealants are wear resistant, are stronger and last longer |
Why are dental sealants important?
The most important reason for getting sealants is to avoid tooth decay. Fluoride in toothpaste and in drinking water protects the smooth surfaces of teeth but back teeth need extra protection. Sealants cover the chewing surfaces of the back teeth and keep out germs and food.
What is dental sealants for adults?
Dental sealant is a thin, plastic coating painted on the chewing surfaces of teeth — usually the back teeth (the premolars and molars) — to prevent tooth decay. The sealant quickly bonds into the depressions and grooves of the teeth, forming a protective shield over the enamel of each tooth.
How much does it cost to seal a tooth?
Dental sealants are a thin coating that is painted on teeth to protect them from cavities. This painless procedure can be $30 to $60 per tooth, although some insurance or discount plans can reduce that cost.
How do dentists put sealants on teeth?
An acid solution is put on the chewing surfaces of the teeth to roughen them up, which helps the sealant bond to the teeth. The teeth are then rinsed and dried. Sealant is then painted onto the tooth enamel, where it bonds directly to the tooth and hardens.
What is the most common cause of sealant failure?
The leading cause of dental sealant failure is due improper placement allowing salivary contamination. This may be in part to clinician’s lack of experience, lack of patient cooperation and an inadequate amount of sealant material used.
