Dental Diseases 2 Flashcards
Damage to ameloblasts during enamel development or exposure of enamel to corosive material
Enamel hypoplasia/hypocalcification
What causes enamel hypoplasia/hypocalcification?
High fevers, distemper, endocrine dysfunction early in life
Why will dentin stain more easily than enamel?
It is porous
Not enough attachment for teeth
Radicular dysplasia
How can you treat enamel hypoplasia/hypocalcification is only a few teeth are affected?
Conservative management, composite restoration and crown
How do you treat diffuse enamel hypoplasia/hypocalcification?
Teeth brushing, regular cleanings, extractions as needed
What antibiotic will stain teeth yellow if given while they are still developing (in utero, <6mo)
Tetracycline
Which layer is affected by tetracycline?
Dentin
Which antibiotic is a better choice to avoid staining?
Doxycycline
pathological wearing due to contact w/opposing tooth (malocclusion)
Attrition
Caused by abnormal contact with crown by a foreign object
Abrasion
What causes dental caries?
Bacteria + carbs = decalcify enamel and dentin
Which teeth are most often affected by caries?
Teeth with flat surfaces
What do dental caries look like?
Brownish, soft, leathery
How do you tx dental caries?
Pulp capping, extraction
What causes focal gingival hyperplasia?
Periodontal disease
Which breed exhibits generalized gingival hyperplasia?
Boxers
What drugs cause gingival hyperplasia?
Cyclosporine, Ca+channel blockers, anticonvulsants
General term applied to anything that can affect the pulp
pulpitis
Why does the tooth look bruised with pulpitis?
Damage to pulp can cause blood cells to break and trickle down to get trapped in the canal
How often is pulpitis reversible?
<10% of the time
Decreased wall thickness, lucency around the apex, and apical root resorption
Endodontic disaese
Occurs b/c affected tooth is not maturing at the same rate as its counterpart in the opposite arcade
Decreased wall thickness
When a tooth fracture considered “complicated”
When pulp is affected/exposed
What are clinical signs of periapical granuloma/abscess?
Nasal disease, intraoral fistula, retrobulbar disease
Which teeth is it likely to see orbital-related clinicla signs and an external draining tract associated with a periapical granuloma/abscess and why?
M1 and M2 sit in base of zygomatic arch
What are draining tracts usually caused by (that’s not a tooth abscess)?
FB
Opening mouth is extremely painful
Retrobulbar disease caused by periapical granuloma
Partially dislocated from alveolus but retains some attachment
Luxation
Completely displaced from alveolus
Avulsion
How long do you have to replace a luxated/avulsed tooth after injury?
30 minutes
