Clinical Flashcards
What are the 4 types of non-carious tooth substance loss?
Attrition - tooth to tooth
Abrasion - foreign object
Erosion - chemical
Abfraction - function
When should we restore a cavity?
Alleviare pain Remove disease Restore tooth integrity, function and aesthetics Aid plaque control High caries risk
When should we avoid restoring a cavity
Patient can access the cavitated lesion with cleaning aids
Prior to cavitation
Small, cleanable cavities with no active caries
Can it be remineralised
Describe a Black’s CI cavity?
Occlusal surface of molars and premolars, buccal pits of molars and palatal pits of anterior teeth
Describe a Black’s CII cavity?
Interproximal surfaces of molars and premolars
Describe a Black’s CIII cavity?
Interproximal surfaces of incisors and canines
Describe a Black’s CIV cavity?
Incisal edges of incisors and canines
Describe a Black’s CV cavity?
Cervical margins
Describe a Black’s CVI cavity?
Cusp tips of molars, premolars and cuspids
What are the 4 anatomical sites of a carious lesion?
Pit or fissure
Smooth surface
Enamel
Root
What are the 3 classifications of caries?
Primary
Secondary
Residual
What are the 3 types of activity of caries?
Active
Rampant
Arrested
Indications for a CI cavity?
Fissure sealant
PRR
Conventional therapy
Indications for a CII cavity?
If confined to enamel - encourage lesion to arrest via Fl
If dentine visible - amalgam or composite possible
Indications for a CIII cavity?
Restore with composite
Indications for a CIV cavity
Composite
Indications for a CV cavity?
Composite
How to prepare a CII cavity?
Caries accessed through MR, due to loss of contact area, with a matrix band
Avoid damage to adjacent tooth
If using amalgam create undercuts
If using composite rubber dam is essential
How to prepare a CIII cavity?
Access caries palatally
How to prepare shallow and deep root caries?
Shallow: - recontoured and Fl applied, if they’re cleansable then restoration may not be necessary
Deep:
- remove caries and restore with GIC or composite
How to prepare a patient for a rubber dam?
General outline to patient
Teeth cleaned and contacts checked with floss
Rough contacts smoothed
If occlusal restoration work planed, occlusion should be marked prior
Lips lubricated
LA given for clamp
How many holes to punch for an anterior tooth?
First premolar to first premolar
