Evaluation of the Success Rate of Pulpal Anesthesia in Mandibular First Molar Following Infiltration of 4% Articaine Alone and as Supplemental Injection After Inferior Alveolar Nerve Block
January 28, 2013 updated by: Kaveh Oloomi, DDS, MS, Zahedan University of Medical Sciences
The purpose of this study is to determine the success rate of pulpal anesthesia in mandibular firs molar following infiltration of 4% articaine alone and as supplemental injection after inferior alveolar nerve block(IANB).

Conditions
Detailed Description
According to inclusion & exclusion criteria, volunteers will be selected and divided into 4 groups randomly.
The clinician who does the injections will not be aware of study purpose.
Also the person who does the electric pulp test (EPT); the volunteer and the statistical analyzer will not be aware of group codes.
Intervention in each group will be as follow: Group 1-Buccal infiltration of one 4% Articaine cartridge with 1/100000 epinephrine.
Group 2-Buccal infiltration of two 4% Articaine cartridges with 1/100000epinephrine.
Group 3-Inferior alveolar nerve block using one 2% Lidocaine cartridge with 1/80000 epinephrine + buccal infiltration of one 4% Articaine cartridge with 1/100000 epinephrine.
Group 4- Inferior alveolar nerve block using one 2% Lidocaine cartridge with 1/80000 epinephrine.
Before injection a control tooth (contralateral canine) will be tested to understand the accuracy of patient's response to EPT; also for measuring the base line vitality, each tooth will be evaluated by EPT twice before injection.
After injection each tooth will be evaluated by EPT every 3 minutes; also every minute the anesthesia of lip and tongue will be checked, up to 15 minutes.
The tooth will be discerned "anesthetized" if the subject will not response to 80 reading of EPT in 2 consecutive tests.
Finally the information will be recorded and in addition to the success rate the mean time for onset of anesthesia and its mean duration time will be evaluated.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Success rate
Time Frame: Every 3 minutes after injection
|
Changes in tooth response to Electric Pulp Tester (EPT) will be checked each 3 minutes after injection.
The anesthesia will be considered successful if the subject will not response to EPT at the 80 reading in 2 consecutive tests.
|
Every 3 minutes after injection
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Onset of anesthesia
Time Frame: Every 3 minutes after injection
|
Changes in tooth response to Electric Pulp Tester (EPT) will be checked each 3 minutes after injection.
No response from the patient at the 80 reading of EPT in 2 consecutive tests will be discerned as "completely anesthetized" and the time will be recorded as "onset of anesthesia".
|
Every 3 minutes after injection
|
Duration of anesthesia
Time Frame: Every 3 minutes after onset of anesthesia
|
Changes in tooth response to Electric Pulp Tester (EPT) will be checked each 3 minutes after onset of anesthesia to determine when the subject will response again at the 80 reading of EPT.
|
Every 3 minutes after onset of anesthesia
