Basics of oral surgery stuff Flashcards
What are some common indications for dental extractions?
caries, pulpal/apical pathology, perio, fractures
When would you consider extraction for a carious tooth?
if there is severe loss of tooth structure and the tooth is unrestorable
Are the teeth that need extraction due to gross caries always painful?
no they can be asymptomatic
When would you consider extraction for a tooth with pulpal or apical pathology?
if RCT is not appropriate or successful, or if a patient would prefer that option
What are the two treatment options once pulp is infected or there is periapical pathology?
extraction or RCT
What is an example of something that would make it extremely difficult to do an RCT?
a markedly curved root
When would you consider extraction for teeth affected by periodontal disease?
if the teeth become so mobile and/or painful that function is impaired or the patients would like an aesthetic improvement
When would you consider extraction for teeth that are fractured?
if the fracture is not restorable
When would you consider extraction of teeth when the mandible is fractured?
if the tooth is in the fracture line and may be in the way of correctly repositioning the bones
When would you consider extraction for teeth affected by non carious tooth surface loss?
to improve aesthetics, if function is impaired, or if the teeth are symptomatic
When would you consider extraction of teeth when there is soft tissue trauma?
if the teeth traumatise the soft tissues, they may need to be removed to improve patient symptoms
What is the most common occasion when teeth are extracted because they are causing soft tissue trauma?
buccally placed upper 8’s can traumatise the cheek or the gum lying over the partially errupted lower 8’s
What is the name for the gum that overlies partially errupted wisdom teeth?
operculum
What are the four types of supernumerary teeth?
conical, tuberculate, supplemental, odontome
What do we mean by a conical supernumerary?
a cone shaped extra tooth
What do we mean by a tuberculate supernumerary?
a barrel shaped extra tooth
What do we mean by a supplementary supernumerary?
just an extra tooth
What do we mean by an odontome supernumerary?
a tooth-like mass
When would you consider extraction for supernumerary teeth?
the potential to impede eruption, displace permanent teeth, cause root resorption
What is the most common supernumerary?
a conical tooth between upper centrals
What are impacted teeth?
teeth that do not reach functional occlusion
When would you consider extraction for impacted teeth?
if they cause root resorption, bone loss around adjacent teeth, develop cystic change
When is the most common situation to extract impacted teeth?
wisdom teeth that are developing symptoms of pericoronitis
Aside from wisdom teeth, what are the second most common impacted teeth?
upper canines
When would you consider extraction of teeth for orthodontic purposes?
to create space so teeth can be aligned
When would you consider extraction pre-orthognathic surgery?
to allow jaw movements to be made more predictably without unerupted wisdom teeth being in the way
When would you consider extraction of teeth as part of treatment for systemic disease?
pre-radiotherapy and pre-bisphosphonate treatment due to risk of osteoradionecrosis/medication-related osteonecrosis of the jaw, as part of resection of a tumour
