Total questions: 17
Worksheet time: 17mins
The pulp horn of primary molars that at greatest risk of exposure during cavity preparation is :
Mesial horn
Distal horn
Mesial and distal horn equally
No risk of pulp exposure during cavity preparation on primary molars .
The carious lesion always appears smaller on the radio- graph than it actually is. Likewise, microscopic observation of ground sections of teeth reveal that the progress of the lesion through the enamel and dentine is more extensive than it is evident on the radiograph:
Both statements are true
Both statements are false
First statement is true second is false
First statement is false second is true
Direct pulp capping is indicated in cases of:
Large carious exposure of the pulp
Small mechanical exposure of the pulp
Non vital tooth
All of the above
material used in indirect pulp capping (IPC) is :
GIC
Ca(OH)2
Zinc oxide eugenol paste
All of the above
After how many months of vital pulp capping with calcium hydroxide a Calcific bridge may be first see no on the radiograph ?
After 2. Weeks
After 1 month
After 6 months
After 12 months
Which of the following may be a reason of failure of vital pulp therapy :
Age of the patient
Presence of microorganisms
Improper choice of capping material
All of the above
Which of the following is the early mean to preserve the vitality of the pulp ?
Pulpotomy
Pulpectomy
Pulp capping
Cvek pulpotomy
The Ca(OH)2 direct pulp capping in primary teeth is not recommended due to the risk of :
Abscess formation
Acute pulpitis
Internal resorption
External resorption
A technique which utilizes calcium hydroxide as liner placed on thin layer of questionable remaining dentin is termed as :
Direct pulp capping
Indirect pulp capping
Vitality test
Compaction technique
Which of of the following is the best barrier between a restorative material and the pulp
Zinc oxide eugenol
Calcium hydroxide
Varnish
Sound dentin
The origin of calcium ions in a calcific bridge over an exposed pulp that covered wit her calcium hydroxide is the :
Blood stream via pulp where exposed
Calcium hydroxide
Local cell debris
Surrounding dentin by redposition
The most successful treatment for vital primary second molar with large carious and pulpal exposure is :
Indirect pulp treatment
pulp capping with calcium hydroxide
Pulpotomy with calcium hydroxide
Pulpotomy with formocresol
Which of following is contraindication for pulp capping And pulpotomy:
Accidental exposure of vital pulp
If there is spontaneous pain or inflammation of the radical are pulp
Greatly curved and tortuous roots
None of the above
IPC procedure on primary molars are indicated when :
Removal of decay has exposed the pulp
A tooth has large , long standing lesion with history of continuous pain
Carious lesion has just penetrated the Dentino-enamel junction
Carious lesion is suspected of producing an exposure of the pulp
Type of calcium hydroxide use do In pulp capping is :
Hard ,self setting Ca(OH)2 [dycal]
Non setting Ca(OH)2
Both hard setting Andy non setting Ca(OH)2 can be used
In order to ensure successful indirect pulp capping the most important criterion is :
Removal of all caries (hard and soft )
Removal of all soft active dentin caries from walls and placement of temporary restoration with excellent sealing properties.
Use an agent that stimulates secondary dentin formation
Non of the aboveboard.
High rate of failure after direct pulp capping in primary teeth is due to :
Law vascularity of the pulp
High cellular content of the pulp
Large number of unmyelinated nerves
Narrow ribbon shapes root canal canals
