Comparison of lignocaine versus articaine local anesthetic solutions in periodontal therapies administered by computerized anesthetic delivery system

Abstract

Objectives: To compare the depth and duration of anesthesia experienced by the patient between lignocaine and articaine anesthetic solutions and to evaluate pain perception and intraoperative anxiety by computer-controlled injection while administering these anesthetic solutions. Materials and Methods: The clinical trial was designed as a randomized, single-center, double-blinded, parallel arm, and comparative study. Examiner and study patients were blinded to treatment assignment during the study. Patients were divided into three groups based on treatment to be performed (Root Planing 30, Curettage 30, and Surgery 20) and were anesthetized with articaine in one quadrant and lignocaine in another quadrant by computer-controlled anesthetic device (WAND®). The duration of anesthesia was self-reported by the patients and was calculated by paired t-test. The pain and anxiety scores were calculated on Wong Baker's Facial Pain/Anxiety Scale' by Chi-square test. Results: Articaine had longer duration of anesthesia than lignocaine in all the three groups (P < 0.000). Articaine showed significantly lesser pain scores than lignocaine in Root Planing Group (P < 0.000). There was no significant difference in anxiety scores between different groups. Conclusion: Articaine has longer duration of anesthesia. Articaine administration was less painful than lignocaine administration.
