About this study

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).

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Success rate

    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.

    Measured: Every 3 minutes after injection

Secondary outcomes (2)
  1. Onset of anesthesia

    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".

    Measured: Every 3 minutes after injection

  2. Duration 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.

    Measured: Every 3 minutes after onset of anesthesia

Questions about this trial

What is this clinical trial studying?

A study testing Lidocaine(IANB), 1 Articaine(Infiltration) and 2 Articaine(Infiltration) in people with Pulpal Anesthesia, run by Zahedan University of Medical Sciences at 1 site in Iran.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Success rate (time frame: Every 3 minutes after injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2013.
