Sealants Flashcards
(43 cards)
Caries Lesions represent a continuum of net mineral ____
loss
What is another name for noncavitated lesion?
initial caries development
Initial caries are characterized by change in…
-Color
-Glossiness
-Surface Structure
Inital caries occur via..
a result of demineralization and represent areas with net mineral loss before there is macroscopic breakdown in surface tooth structure
Are initial caries reversible?
Considered Reversible with remineralization
What are cavitated lesions?
Loss of surface integrity with inability to biologically replace the loss of hard tissue
Whats the difference between moderate and advanced caries?
Moderate Caries
-Extend into the middle third of dentin layer
Advanced Caries
-Extend into the inner third or dentin layer
What are the tooth surface sites or origins?
- Pit & Fissure
- Approximal
- Cervical and Smooth Surface
- Root
What are the main caries detection techniques?
- tactile
- radiographs
- newer techniques
What are radiographs especially good for in terms of caries detection?
Especially for interproximal lesions
What are new techniques for caries detection?
Laser fluorescence, transillumination, or combo of laser luminescence and photothermal radiometry
What is ICDAS 0
clinically sound
What is ICDAS 1-2
clinically detected “intact” enamel lesions (intial stage decay)
What is ICDAS 3-4
clinically detectable early, shallow, or microcavitations (moderate decay)
What is ICDAS 5-6
clinically detectable late or deep cavitations (extensive decay)
What do you make a caries management plan for a patient based on?
- ICDAS
- inital patietn assessment
- lesion detection, activity, and appropraite risk assessment
- synthesis and decision making
- clinical treatmetns with prevention
What are the high risk characteristics for caries?
- Sugary food or drinks
- Eligible for government programs (WIC, Headstart, age 0-6)
- Caries experience of caregiver (age 0-14)
- Special health care needs
- Chemo/Radiation therapy
- Restorations/Cavitated carious lesions in the last 24 months
- New Noncavitated (incipient) lesions in the last 24 months
- Teeth missing due to caries
- Severe dry mouth
What are different caries prevention and risk management strategies?
-Behavioral Modification
-Topical Fluoride Application
-Pit and Fissure Sealants
What are ways of behavioral modification to manage caries?
-Limiting sugary foods and drinks
-Chewing sugar-free gum with xylitol
-Brushing with fluoride toothpaste 2x/day
-Cleaning between teeth 1x/day
What are different ways of topical fluoride application?
-Placement of fluoride varnish (2.26%)
-Placement of fluoride gel (1.23% acidulated phosphate)
-Daily use of 0.09% fluoride mouthrinse
-Silver Diamine Fluoride (38%) for arrest of dental caries
Are pit and fissure sealants effective?
-Effectively penetrating and sealing these surfaces with dental material (sealants) has been proven effective in preventing and arresting caries in permanent molars of children and adolescents
Why do pit and fissures need sealants sometimes?
Anatomical grooves (aka pits and fissures) of teeth trap food particles and promote presence of bacterial biofilm, increasing the risk or caries
When should you place sealants?
-Sealants are placed on pit and fissure areas only on noncavitated teeth
When is the best time to seal permanent molars?
overall higher prevalence of untreated carious lesions in 12-19 year olds (15%) compared to 6-11 year olds (6%), so best to seal soon after permanent molar eruption
