SEALANTS - CHAPTER 59 EXAM
QUESTIONS AND ANSWERS
Dental Sealants - Correct Answers -Protective coating that is easily applied to teeth to
prevent bacteria and food particles from settling;
Prevents dental caries in pits and fissures
Fluoride - Correct Answers -Pits and fissures of the teeth do not benefit from the effects
of __________ as much as smooth enamel surfaces do
Cavities - Correct Answers -Scientific studies have proved that properly placed dental
sealants are 100% effective in preventing the development of ____________ in sealed
tooth surfaces
Dentinoenamel - Correct Answers -Pits and fissures are often deep, narrow channels in
the enamel surface that can extend close to the _________________ junction
Acrylate - Correct Answers -Do not use sealants on patients with known _________
allergies
Soap and water - Correct Answers -Use protective gloves and a no-touch technique;
If skin contact occurs, wash the exposed skin with __________ ______ _________;
Acrylates may penetrate gloves;
If sealant touches glove, remove and discard glove, wash hands immediately and re-
glove
Water - Correct Answers -If accidental eye contact or prolonged contact with oral soft
tissue should occur, flush with large amounts of __________;
Protective glasses should be used by operators when using light-cured resins;
Protective eyewear should also be provided for the patient during sealant procedures
Quickly - Correct Answers -Enamel at the base of the fissures is thinner than the
enamel around the rest of the tooth;
This means that deep, narrow fissures can make it more likely that tooth decay will
occur, and any decay that does form will penetrate through the thin enamel and
progress more ___________ into the pulp
Toothbrush bristle - Correct Answers -Pits and fissure on the teeth are so tiny that even
a single _____________ ___________ is too large to enter for cleaning purposes
, Sealant - Correct Answers -A physical barrier that prevents decay;
Small food particles and plaque cannot penetrate through or around it;
If the sealant remains intact, the tooth is protected;
If a part of the sealant or bond is broken, the protection is lost
Cannot - Correct Answers -Bacteria (can/cannot) survive beneath a properly placed
sealant because the carbohydrates that they need to survive cannot reach them
6-15 - Correct Answers -Pit and fissure sealants are especially useful through the
caries-active period ( ____ - _____ years) and may delay the need for an occlusal
restoration unless a proximal lesion develops
Indications for use of sealants - Correct Answers -The tooth on the opposite side of the
mouth has similar pits and fissures. This includes that the tooth on the other side has a
similar risk for decay. if the tooth on the opposite side has decay or a filling the tooth in
question may decay and may also need a filling;
Adjacent molars have or need occlusal resorations. When the teeth beside the tooth in
question have fillings or need fillings, that tooth also may develop decay;
The tooth is newly erupted. The highest risk period for decay occurs within the first 3
years of eruption;
The tooth is fully erupted. If a sealant is to be placed, the entire occlusal surface must
be exposed. If it is not, the sealant cannot be placed;
No proximal decay is noted. If a filling must be placed to restore the proximal surface
after the sealant has been placed the selanat will break off;
Sealants are used in conjunction with a fluoride program. This is an indication because
fluoride program. This is an indication becayse fluoride helps reduce the risk for decay
and will complement the role of the sealant in preventing decay
Contraindications to sealants - Correct Answers -Lack of deep pits and fissures;
Obvious dental decay;
Proximal surface decay;
Insufficiently erupted teeth;
Primary teeth expected to be lost soon;
Poor patient cooperation in the dental chair
Polymerization - Correct Answers -Sealants are classified by their method of
_____________, their sealant content, and their color.
Self-cured materials - Correct Answers -supplied as a two-part system (base and
catalyst);
When these pastes are mixed together, they quickly polymerize (harden);
Usually set within 1 minute of application
Light-cured sealants - Correct Answers -do not require mixing;
After the material has been applied to the tooth, the curing light activates the setting;
