Enamel hypoplasia or hypocalcification is caused by …?
Damage to ameloblast during enamel development or exposure of enamel to corrosive material… can be due to high fever too
What are the two forms of treatment for enamel hypoplasia ?
Focal - restore defect with composite
or place several teeth cap to prevent wear
Which drug can cause teeth to turn yellow?
Tetracycline
Which layer is affected in the teeth for tetracycline staining?
Dentin
Doxycycline cause less yellowing of the teeth compare to Tetracycline. T/F?
True
What is meant by dental attrition
When there is pathologic wearing due to contact with opposing tooth –> malocclusion
What is meant by dental abrasion?
Caused by abnormal contact with crown surface by a foreign object eg: tennis ball, rocks etc
How would you treat a dental abrasion?
Remove offending objects and monitor for pulp exposure and crown fractures
How would you treat dental attrition?
- orthodontic correction
- crown reduction
- extraction
How do you determine if there is an endodontic exposure ?
Probe with an explorer- if it enters the chamber, extract or do a root canal.
Reparative tertiary dentin is brown and hard.
What is the cause of dental caries?
Bactetria produce organic acids that in the presence of carbs decalcify enamel and dentin

What are the six classifications of tooth fracture?
- Enamel infraction (Abraction )
- cracks in the enamel and no loss of structure - Enamel fracture
- loss of enamel only - Uncomplicated crown fracture
- pulp chamber is not exposed - complicated crown fracture - pulp is exposed
- uncomplicated crown/root fracture
- crown is NOt exposed - Root fracture - extract
What is the treatment for uncomplicated/enamel fractures?
Indirect pulp capping or crown restoration
What is the treatment for complicated fractures?
Vital pulpotomy (option in very young animals) or root canal Crown restoration or extraction of tooth
