Principles Of Cavity Design Flashcards
What does the acronym KISS stand for?
Keep it small and simple
What can cause a cavity?
Caries
Trauma
Tooth wear
Developmental conditions
When to intervene?
Alleviate pain
Restore form, function and appearance
Aid plaque control
High caries risk- prevention
What is minimally invasive dentistry?
Early detection of disease
Risk assessment
Diagnosis
Prevention/ control of further disease
If intervention is needed, what do you remove from the tooth?
Excavation of unrepairable diseased enamel and dentine only
What are the reasons for restoring the tooth?
Support and strengthen
Promote remineralisation
Seal off any remaining bacteria
Restore appearance, form and function, for long term success
What are terms used to describe the features of a cavity?
Floor
Proximal box
Isthmus
Cavosurface angle
What are the 2 ways to describe the floor of a cavity?
Occlusal floor
Gingival floor
When do you use the occlusal and gingival floor?
Cavities usually cut into 2 levels
Floor closest to the occlusal surface is the occlusal floor
Cavity closest to the gingiva is the gingival floor
What is the pulpal box?
A box that is prepared to gain access to caries in the interproximal region
Normally made by sacrificing the marginal ridge
What tooth structure does a proximal box sacrifice?
Marginal ridge
What is the pulpo-axial wall?
The side wall of the box that runs alongside the pulpal wall
What is the isthmus?
a part of the restoration or several parts of the restoration which are narrow and connect 2 larger parts
What is shown in the diagram?
Isthmus
Between the occlusal and mesial/distal surfaces
Where is the isthmus is a class II MO restoration?
Between the occlusal and proximal surface
What is the cavosurface angle?
The angle between the prepared surface and the untouched surface of the tooth
