Assessment of anesthetic efficacy of 4%articaine and 2%Lidocaine during implant pilot hole preparation in the mandibular posterior region infiltration

Abstract

Aim.The aim of this study was to evaluate and compare the anesthetic efficacy of 4%
articaine and 2% lidocaine (both with 1:100,000 epinepherine) for buccal and
lingual infiltration in patients need implant placement.
Materials and methods.Forty patients have edentulus regions posterier to mental
foramen were divided into 4 study groups and received buccal and lingual
infiltration of either 4% articaine or 2% lidocaine. Surgical procedure was begun
5 minutes after solution deposition. Success was defined as no or mild
discomfort (VAS recordings) during during pilot hole drill.
Results.The success rate for mandibular infiltration to produce anesthesia using
articaine was 100% in premolar and molar area for the articaine solution and
success rate was 80% in preamolar and 30% in molar area. There was high
significant difference between the articaine and lidocaine solutions (ANOVA P
< 0.001).
Conclusion. The efficacy of 4% articaine was superior to 2% lidocaine for
mandibular posterior regoin.
