Sealants and Restorative Dentistry In Pediatric Dentistry Flashcards
What is the Continuum of Preventive and Restorative Care of SOUND TEETH?
- Sound tooth
- Incipiency
- Limited Cavitation
- Gross Cavitation with Loss of Structural Integrity
- Unrestorable Tooth Structure
What is the Continuum of Preventive and Restorative Care of SEALANTS?
- Sealants
- Preventative Resins
- Restoration
- Full Coverage+- Pulpal Therapy
- Extraction
What resin is used in most current commercial sealants?
bis-GMA resin
Do low levels of BPA in sealants pose a known health threat?
No
True or False: The cariostatic properties of sealants are attributed to the physical obstruction of pits and grooves.
True
What are the four categories in the Venn diagram describing carious lesions on teeth
- Tooth
- Sugar
- Bugs
- Time
What is the rationale for the use of sealants?
Bonded resin sealants, placed by appropriately trained dental personnel, are safe, effective, and underused in preventing pit-and-fissure caries on at-risk surfaces. Effectiveness is increased with good technique and appropriate follow-up and resealing as necessary.
True or False: Placing sealants on MINIMAL-enamal caries is not effective at inhibiting lesion progression?
False
What are indicators clinicians use to determine the need for sealants?
- Tooth morphology
- Clinical diagnostics
- Past caries history
- Past fluoride history
- Present oral hygiene
True or False: The potential benefit for sealants can be found on any tooth, but is limited to the permanent teeth of adults?
False: It is good for primary teeth as well
True or False: Placement of a high-viscosity, hydrophobic material-bonding layer as part of or under the actual sealant has been shown to enhance its long-term retention and effectiveness.
False: low-viscosity, hydrophilic
True or False: Glass-ionomer materials have been shown to be ineffective as pit-and-fissure sealants but can be used as transitional sealants.
True
What are the steps in applying sealants to dentition?
- Identify susceptible tooth
- Clean tooth with rotary brush
- Etch the tooth
- Clean and dry tooth
- Apply bonding agent
- Apply sealant
- Polymerize and check for voids
- Adjust occlusion
What are the six indication for full coverage?
- Restorations for teeth with extensive and/or multiple caries lesions
- Restorations for hypoplastic teeth that cannot be adequately restored with bonded restorations
- Restorations for teeth with hereditary anomalies, such as dentinogenesis imperfecta or amelogenesis imperfecta
- Restorations for pulpotomized or pulpectomized teeth with increased danger of fracture of the remaining coronal tooth structure
- Restorations for fractured teeth
- Restorations for primary teeth to be used as abutments for appliances or attachments for habit breaking and orthodontic appliances
Posterior Stainless Steel Crowns - Selection
- Smallest crown that fits appropriately
- Correct occlusogingival crown length which includes no interference with occlusion and 0.5 – 1 mm subgingival
- Trim and contour for adaptation to tooth and follow natural contours of marginal gingival tissue
- It is POSSIBLE to shape and contour the stainless steel crown to the remaining tooth structure
