Minimally Invasive Dentistry - Cavity Classifications Flashcards
What are reasons to perform restoration?
Developmental
Tooth fracture
Loss of restoration
Caries
When would you not restore cavities?
The patient can access the cavitation lesion with cleaning aids
Prior to cavitation, preventative means can be used
Small, cleansable cavities with no active caries
It can be demineralised?
What is important to do before you restore a tooth?
Find the cause
What does minimally invasive mean?
Removal of the unrepairable diseased enamel and dentine ONLY
physically and chemically modifying the remaining cavity
What is the goal when restoring cavities? .
Support and strengthen the remaining structure
Promote remineralisation
Seal off any remaining bacteria from the nutrition supply arresting the various process in the residual caries within the cavity depths
Why classify caries?
To describe/ quantify
To diagnose
To manage and treatment plan
What are the 3 ways we can classify cavities?
Anatomically
By activity/ time
Level of disease
What is the Black’s classification of cavities?
By the surface
Class I-IV
What is class I of blacks classification?
Occlusal surfaces of molars and premolars, buccal, pits of molars, palatal pits of anterior
What is class II of blacks classification?
Caries effecting proximal surfaces of molars and premolars
What is class III of blacks classification?
Caries effecting proximal surfaces of central incisors, lateral incisors and cuspids without involving the incisal angles
What is class IV of blacks classification?
Caries affecting proximal including incisal angles of anterior teeth
What is class V of blacks classification?
Caries affecting gingival one-third of facial or lingual surfaces of anterior or posterior teeth
Cervical margin
What is class IV of blacks classification?
Caries affecting cusp tips of molars, premolars and cuspids
What part of the ca it’s will you remove?
Margins of the cavity
Keep a layer of dentin to protect the pulp
