Evaluation of Anesthesia Efficiency of Local Infiltration with Articaine 4% and Mental Nerve Block with Lidocaine 2% in Extraction of Mandibular Anterior Teeth

Comparison of anesthesia efficiency of local infiltration with articaine 4% and mental nerve block with lidocaine 2% in extraction of mandibular anterior teeth

A clinical trial with parallel, double-blind, randomized, phase 3 groups on 54 patients was used for Excel software randomization.

Patients referred to Alborz Dental Clinic in Urmia for extraction of mandibular anterior teeth and interested in participating in this study, will be divided into two groups: lidocaine recipient and articaine recipient. In both groups, the standard injection with a 25 gauge needle with a short length will be performed slowly (1 minute) by a surgeon under the same conditions. Epinephrine 1: 100000 vasoconstrictor (made by Iran Elixir) will be injected for buccal infiltration and 0.3ml (about one-eighth of the cartridge) for lingual infiltration. In the second group, after needle insertion and negative blood aspiration, 1.5 ml of 2% lidocaine anesthetic solution with vasoconstrictor epinephrine 1: 100000 (made by Iran Elixir) by mental block method and 0.3 ml (about one-eighth of the cartridge) ) Will also be injected for lingual infiltration.

Patients with age range of 18-45 At least one mandibular anterior tooth No systemic problems No allergies to anesthetic solutions used Absence of inflammation and soft tissue infection near the injection site Do not take painkillers 24 hours before treatment

In the first group, 4% articaine anesthetic solution with 1: 100000 epinephrine vasoconstrictor (made by Iran Elixir) and in the second group, 2% lidocaine anesthetic solution with 1: 100000 epinephrine vasoconstrictor (made by Iran Elixir) will be injected.

Pain level of patients during surgery based on SEM scale.

Patients are randomly divided into two groups of 27 based on limited randomization and using the law of random allocation. Randomization based on a single sequence of random allocations is called simple or unlimited randomization. Simple randomization is one of the most common methods used to perform the randomization process. In this method, there is a possibility of inequality in the number of people assigned to each group, especially in studies with a small sample size. While according to the probability hypothesis, with increasing the sample size, this inequality will be greatly reduced and the division will be based on the coin toss.

Researchers will be blind to the process of randomization and sample allocation. The patient's pain will be assessed by a second person who will be on the blind injection.
