• THE FOLLOWING INCLUDE ALL OF THE QUESTIONS FROM THAT ONE LADY’S LAST LECTURE (WEEK BEFORE THE LAST LECTURE)

– Which one of the following tests would be most important for distinguishing between reversible pulpitis and symptomatic irreversible pulpitis?

• Transillumination• Electric pulp• Percussion• Palpation• Thermal test

– Which would be most important to distinguish between acute apical abscess and phoenix (2nd acute from existing lesion)?

• Thermal test• Electric pulp• Radiographic exam• Perio exam• Palpation and percussion

– Which is best to distinguish signs/symptoms of endo origin from signs and symptoms of perio orgiin?

• Thermal tests, electric pulp, perio probling• Thermal tests, perio probing, percussion• Electri pulp, palpation, percussion• Periodontal probing, percussion , palpation• Elecyric pulp, palpation, transilluminatio

– During exam of oral tissue, draining fistula buccal to #4. Large MOD alloy, insensitive to percussion and ice. Xray shows PDL lesion over apex of buccal root. Diagnosis:

• Phoenix abscess• Irreverible pulpitis• Chronic apical periodontitis• Necrosis• Acute periodontal abscess

– When 4th root canal exits in a max first molar, why is it found in Mesiofacial root?’

• Tendencies toward root fusion• Broad MD• Broad buccal-palatally• None of above… 3 canals

– Which is not ingredient of grossman’s root canal sealer?

• Ba sulfate• Zn oxide• Staybalite resin• isoprene• eugenol

– Which is false regarding use of sodium hypochlorite?

• interacts w/peroxide, to effervesce dentinal shavings and debris

• Should be used sparingly in extensively calcified canals (should be copiously)

– Which is not objective in cleaning and shaping?

• Develop continuously tapering funnel prep in occusal apical direction

• Maintain the foramen at its original spatial position• Keep dimensions of the apical foramen as small as

is practically possible• Enlarge the apical terminus of the _____

– What characteristic do the clinical entities of pulp polyps and early nonperformating internal resportion have in common?

• Dental history of trauma• History of spontanous _____ • Usually asymptomatic

– Gates glidden drills should ideally be used:• End cutting in apical direction• Widen canal in middle and apical 3rd• Blend coronal half of canal into access cavity

(because blunt at tip)• Prior to initial use of endodontic patency file• All of above

– Incidence of mandibular incisors have 2 root canals?

• 29%• 40%• 60%• 80%

– Episodic exposure to acid released by bacteria inside an incipient carious lesion can have the following effects on pulp except:

• Formation of irritation dentin• More dead tracts• Excruciating toothache pain• Decrease in pulp volume

THE FOLLOWING SLIDES ARE ALL OF THE QUESTIONS FROM Dr. Gluskin’s Last Lecture of the Quarter

– All describe pulpal extirpation but:• is “extracting the root” from the canal• extirpation in a large canal is best accomplished

with broach• In narrow canals needs files

– Complications in untreated endodontic infections include all but:

• excessive calcification
