Brief summary

Context: Lidocaine and articaine are two of the most commonly used local anesthetics in dentistry. Lidocaine has often been the anesthetic of choice in clinical practice, but in clinical experience, articaine has proven to be more effective in controlling pain during dental procedures. (Camps-Font, O. et al. 2020). There are still unanswered questions, such as which of the two local anesthetics is more effective in reducing pain? This could lead us to discuss which one to choose to reduce costs in the dental office. Objective: The objective of this project is to determine and compare the effectiveness of lidocaine and articaine in clinical contexts such as tooth extraction with infiltrative techniques, seeking to provide answers that will optimize the choice of anesthetic based on the patient and the procedure, thus improving pain management and reducing costs in the dental office. Design: Randomized double-blind experimental study, parallel groups. The control group received 2% lidocaine, and the experimental group received 4% articaine. The study will be conducted in accordance with the guidelines of the Consolidated Standards of Reporting Trials (CONSORT 2010). The probabilistic sampling technique is through simple randomization. The 100 patients who meet the inclusion criteria will be randomly assigned to the control and experimental groups in a 1:1 ratio. Expected results: articaine shows a lower percentage of extractions with anesthetic reinforcement and, therefore, a lower average number of additional tubes.

Masking description

Blinding will be performed by the study investigators. The RCT is a double-blind trial, where neither the operator nor the patient knows the result of the anesthesia being administered. The preparation of the intervention will be carried out by dividing the anesthetic cartridges, 50 for the control group (lidocaine) and 50 for the experimental group (articaine). Since both articaine and lidocaine are from the same manufacturer, they have the same color silicone plunger, so we will simply cover the logo with an adhesive sticker and store them in a box. To distinguish which of the tubes corresponds to articaine or lidocaine once they have the sticker, they will be assigned the same numbers that will be used to randomize each patient (1 and 2 interleaved), with No. 1 being articaine and No. 2 being lidocaine. These will be in their respective boxes with their numbering.

Intervention model description

Randomized, double-blind, parallel-group experimental study. Control group: 2% lidocaine; experimental group: 4% articaine. The RCT will be conducted in accordance with the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines.
