The Pulp and Periodontium Diseases Flashcards
what is the pathway of disease after a tooth has been infected with caries
pulp hyperaemia
acute pulpitis - chronic
acute apical periodontitis
acute apical abscess - chronic sinus
chronic apical infection
apical cysts
infected apical radicular cyst
what are the clinical features of hyperaemia
pain lasting for seconds
stimulated by hot/cold or sweet foods
resolves after stimulus
caries approaching pulp but tooth can still be restored without treating pulp
what are the clinical features of acute pulpitis
constant severe pain
reacts to thermal stimuli
poorly localised pain
referral of pain
no response to analgesics
often symptoms less severe
what helps aid your diagnosis of acute pulpitis
history
visual examination
no TTP
pulp testing is equivocal
radiographs
diagnostic local anaesthetic (numbs sore area)
removal of restorations
what gives you a diagnosis of acute apical periodontitis
TTP
non-vital tooth
slight increase in mobility
loss of clarity of lamina dura
radiolucent shadow
delay in changes at apex of tooth
widened apical periodontal space
what is the cause of traumatic periodontitis
parafunction
what is included in the diagnosis of traumatic periodontitis
clinical examination of occlusion
TTP
vital tooth
radiographs show general widening of PDL
how do you treat traumatic periodontitis
occlusal adjustment
therapy for parafunction
what are the types of pus producing infections
acute apical abscess
periodontal abscess
pericoronitis
sialadenitis
what organisms are included in abscesses
polymicrobial
anaerobes
what are the symptoms of abscesses before it perforates bone
severe unremitting pain
acute tenderness in function
acute tenderness on percussion
what are the symptoms of abscesses after perforating through bone
pain remits
swelling, redness and heat apparent
pain returns with swelling
initial reduction in TTP
what does the site of a swelling depend on
position of tooth in arch
root length
muscle attachments
spaces in proximity to lesion
what is the treatment for abscesses
drainage
determine antibiotic need
what is the need for antibiotics determined by
severity
absence of adequate drainage
