DENTISTRY 4 Flashcards
what is tooth resorption (TR) ?
Tooth resorption (TR)- resorption of the dental
hard tissues
what is internal resorption (RR)?
Internal Resorption (RR)- Resorption originating
in the pulp cavity
what are some signs of tooth resorption?
- Irritative gnawing
movements - Avoiding using teeth on one
or both sides - Red spot type lesions may
be seen on crown - Lesions v painful and
vascular when probed - Probably multiple missing
teeth
what are stage 1, 2, and 3 of tooth resorption?
DUN RLLY KNOW HOW THIS IS DIFFERENT THAN THE TYPE 4S
what si the different btwn 4a, 4b, and 4c tooth resorption?
4a-crown and root equally affected
4b- crown more affected than the root
4c- root more affected than the crown
tx for tooth resorption?
-radiography
-either surgical extraction or crown reduction w intentional root retention
describe the extraction process for type 2 tooth resorption?
-envelope flap
-crown amputations
-intentional tooth retention
-crystal alveoloplasty
-suture flap back
which animal gets more tooth resorption: dogs or cats?
cats
what technique is this for dental x-rays?
parallel technique
what is this technique for dental x-rays?
-some common errors in this technique?
bisecting angle technique
what are some drug options for maxillofacial nerve blocks?
-lidocain, bupivicaine, mepivicaine,
in a nerve block, are we anaesthetising everything rostral or caudal to the dental block?
rostral
which is adequate for anaesthetising molar teeth: infra-orbital block or maxillary block?
describe area to perform a maxillary nerve block?
pop needle just caudal to last molar. through mucosa & no deeper
which type of nerve blocks should not be done in cats?
infra-orbital
what are the 3 types of mucogingival falps?
-envelope flap
-mucogingival triangular flap
-mucogingival pedicle flap
what are some complications to tooth extractions?
-fractured roots
-haemorrhage
-dehiscence
-iatrogenic jaw fracture
-enamel defects
-instrument slippage: orbital damage/brain damage
