Oral Path Exam 1

Front 1

causes of pulpal inflammation

Back 1

1.mechanical 2.thermal 3.chemical 4.bacterial

Front 2

mechanical damage

Back 2

1.trauma 2.iatrogenic 3.attrition 4.bruxism 5.abrasion 6.abfraction

Front 3

thermal injury

Back 3

mostly iatrogenic; veneers have >5% pulpal necrosis, full gold crowns >13%, crown and foundation>17%

Front 4

chemical irritation

Back 4

erosion, iatrogenic(etching)

Front 5

bacterial effects

Back 5

caries

Front 6

symptoms

Back 6

what patient reports

Front 7

signs

Back 7

what you see clinically

Front 8

normal, healthy pulp characteristics

Back 8

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

Front 9

purpose of inflammation

Back 9

protective response of tissue to local injury; tries to eliminate, dilute, or wall off injurious agent; heals damaged tissue

Front 10

without inflammation:

Back 10

infections would go unchecked; wounds would never heal

Front 11

cardinal signs of inflammation

Back 11

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)

Front 12

reversible pulpitis- clinical findings

Back 12

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

Front 13

reversible pulpitis- radiographic findings

Back 13

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

Front 14

irreversible pulpitis- clinical findings

Back 14

1.spontaneous pain 2.prolonged response to thermal stimuli(may be delayed) 3.if confined to pulp-percussion and palpation tests are WNL

Front 15

irreversible pulpitis- radiographic findings

Back 15

1.if confined to pulp, may not be diagnostic 2.if advanced, widened PDL due to apical inflammation 3.may see etiologic factors

Front 16

other unusual presentations of irreversible puplitis

Back 16

hyperplastic pulpitis and internal resorption

Front 17

hyperplastic pulpitis

Back 17

pulp polyp; granulation tissue; pyogenic granuloma from pulp; low grade chronic irritation; usually teeth w/ open apices; ample vascularity of young pulp; usually asymptomatic

Front 18

internal resorption

Back 18

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

Front 19

pulp necrosis- clinical findings

Back 19

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

Front 20

pulp necrosis- radiographic findings

Back 20

1. normal or widened PDL space 2.PA radiolucency
