NCT01912755

Brief Summary

The aim of this study was to verify the effectiveness of an anesthetic called articaine for dental treatment, comparing it with an anesthetic commonly used in dental clinic: lidocaine. Two types of local anesthesia (oral injection) in accordance with the solution used were performed. For patients anesthetized with articaine, an injection of anesthesia close to the tooth to be treated was used. For the anesthetic lidocaine an injection on the cheek at the bottom of the mouth was made. Differences between both techniques are mainly regarding the area of numbness. In the injection with articaine only a small part of the lip and the tooth was anesthetized. With lidocaine injection, the lower region of the entire side of the tooth and half of the tongue on the same side was numbed. The treatment was electronic randomized and there was equal chance to one or another treatment. The investigators are studying this new form of anesthesia (near the tooth that was treated) to see if it can numb the tooth to an emergency treatment, if it really decreases the feeling of numbness and discomfort during the service. Patients receiving articaine were submitted to cone beam exam at no cost.

Outcome Measures

Primary Outcomes (1)

  • Pain perception 3

    Patients received visual analogue scales (VAS) to record their pain perception ten minutes after local anesthetic injection.

    10 minutes after injection

Secondary Outcomes (4)

  • Buccal cortical bone thickness

    one week after injection

  • Root distance to the bone

    one week after injection

  • Basal pain perception

    10 minutes before injection

  • Pain perception 2

    5 minutes before injection

Study Arms (2)

Articaine

EXPERIMENTAL

injection of 1.8 mL buccal infiltrations of 4% articaine with 1:100,000 epinephrine in one tooth with a clinical diagnosis of symptomatic irreversible pulpitis.

Drug: 4% articaine with 1:100,000 epinephrineDrug: 2% lidocaine with 1:100,000 epinephrine

Lidocaine

ACTIVE COMPARATOR

1.8 mL 2% lidocaine with 1:100,000 epinephrine injected as inferior alveolar nerve block in the mandible side with one tooth with a clinical diagnosis of symptomatic irreversible pulpitis.

Drug: 4% articaine with 1:100,000 epinephrineDrug: 2% lidocaine with 1:100,000 epinephrine

Interventions

If the primary anesthesia failed after ten minutes, an intraligamentary injection with 4% articaine with 1:100,000 epinephrine was performed and the procedure initiated. When access to the pulp chamber was available, intrapulpal anesthesia was given using 4% articaine with 1:100,000 epinephrine.

Also known as: articaine
ArticaineLidocaine

If the patient reported pain during treatment and access to the pulp chamber was not achieved, an IANB was performed with 2% lidocaine with 1:100,000 epinephrine.

ArticaineLidocaine
