causes of pulpal inflammation
|
1.mechanical 2.thermal 3.chemical 4.bacterial
|
|
mechanical damage
|
1.trauma 2.iatrogenic 3.attrition 4.bruxism 5.abrasion 6.abfraction
|
|
thermal injury
|
mostly iatrogenic; veneers have >5% pulpal necrosis, full gold crowns >13%, crown and foundation>17%
|
|
chemical irritation
|
erosion, iatrogenic(etching)
|
|
bacterial effects
|
caries
|
|
symptoms
|
what patient reports
|
|
signs
|
what you see clinically
|
|
normal, healthy pulp characteristics
|
1.no spontaneous symptoms 2.mild transient resonse to thermal/electrical stimuli 3.no painful responses 4.clearly delineated canal that tapers smoothly toward apex 5.intact lamina dura 6.no root resorption 7.may have canal calcifications w/ no other symptoms
|
|
purpose of inflammation
|
protective response of tissue to local injury; tries to eliminate, dilute, or wall off injurious agent; heals damaged tissue
|
|
without inflammation:
|
infections would go unchecked; wounds would never heal
|
|
cardinal signs of inflammation
|
1.redness(dilation of vessels) 2.swelling(escape of fluid) 3.pain(tissue pressure and inflamm. mediators) 4.heat(inc. blood supply) 5.loss of function(b/c of pain and swelling)
|
|
reversible pulpitis- clinical findings
|
1.mild/moderate inflammation of the pulp 2.no spontaneous symptoms 3.transient/sharp response to thermal stimuli 4.may respond to sweets 5.no pain from biting
|
|
reversible pulpitis- radiographic findings
|
1.clearly delineated canal that tapers towards apex 2.intact lamina dura 3.no root resorption 4.may have canal calcifications w/out other symptoms 5.may see etiologic factors
|
|
irreversible pulpitis- clinical findings
|
1.spontaneous pain 2.prolonged response to thermal stimuli(may be delayed) 3.if confined to pulp-percussion and palpation tests are WNL
|
|
irreversible pulpitis- radiographic findings
|
1.if confined to pulp, may not be diagnostic 2.if advanced, widened PDL due to apical inflammation 3.may see etiologic factors
|
|
other unusual presentations of irreversible puplitis
|
hyperplastic pulpitis and internal resorption
|
|
hyperplastic pulpitis
|
pulp polyp; granulation tissue; pyogenic granuloma from pulp; low grade chronic irritation; usually teeth w/ open apices; ample vascularity of young pulp; usually asymptomatic
|
|
internal resorption
|
inflammation may initiate resorption; may happen after trauma; usually asymptomatic; pulp and periapical tests are WNL; inflamed pulp must be removed; identified by radiographs and or pink spot in crown
|
|
pulp necrosis- clinical findings
|
total or partial death of pulp, multi-rooted teeth fifficult to diagnose; 1. asymptomatic until PDL is affected 2.no response to thermal or EPT tests 3.may have discoloration
|
|
pulp necrosis- radiographic findings
|
1. normal or widened PDL space 2.PA radiolucency
|
