Pt assessment for extraction Flashcards
What is metronidazole prescribed for?
Antibiotic for anaerobic bacteria
Sedation drug?
Benzodiazepine
Types of benzodiazepine?
Diazepam
Valium
Dental history?
Previous treatment, especially XLAs
anxiety
- preference for sedation or GA
Previous XLA difficulty
Previous dry socket
History of previous XLA?
Did it require stitches
Ow ling were you in the chair
Did it hurt during the extraction
Why be wary if it’s the pt first extraction?
Will they bail out
Might discover a bleeding disorder they were unaware of
Ethnicity/gender and bone density?
Afro-Caribbean males (especially f heavy built) often have more dense bone
Age and extraction?
Older more brittle/ Less elastic bone
TMJ and extraction?
Pre-existing TMD
Mouth opening and extraction?
Access
Pt usually open up around 3-4 cm
Swelling and extraction?
LA efficacy
Painful to suppport mandible if swollen
IO exam - what are you looking for in soft tissue?
Overgrowth and coverage of retained roots
IO exam - what are you looking for with regards to teeth?
- Heavilyrestored/RCT
– Fractures/coronal integrity
– densereactive bone
– partially erupted / infraoccluded
– Adjacentteeth
– Mobility
Relevance of Bone and extractions?
- Thick zygomatic buttress overlying upper first molars
– External oblique ridge overlying lower molars
– Tori lingual to lower premolars
Why is the 7/8 harder to extract?
External oblique ridge and internal oblique ridge
Can’t move buccal and lingially is the lingual nerve - refer an 8
What direction do the palatal root want to one put of upper molars?
Bucally
Adjacent anatomical structures?
Maxillary antrum - upper 5,6,7,8,
Mental foramen - lower premolars
IAN - lower wisdom teeth
Hypercementosis?
Large cementum
What has longer roots, 6 or 7?
6
Where do you grab a tooth for extraction?
Bone level
Describe these roots? 46
Sclerosed
What do you call it when you take a tooth out and expose sinus?
Oro-antrum communication
Conical roots?
One rounded root - e.g 8s, 5s
What is going on with this root?
Dilaceration
Describe this radiograph?
Radiolucency- lack of trabecular
Osteolytic lesion - eating away at bone
Caries in 46 but non cavitation
Monolocular - infection around both roots
Cysts at apex
What is occuring at 21?
Internal resorption - making tooth weaker
Difficult extraction
What is occuring at 36?
Hypercementosis at apex of distal root
47?
Submerged or infraoccluded
Lying on inferior alveolar
