title: Anaesthetic efficacy of 4% articaine mandibular buccal infiltration compared to 2% lignocaine inferior alveolar nerve block in children with irreversible pulpitis.
abstract: BACKGROUND
  Lidocaine is the gold standard anaesthetic solution that has been used since its inception into dentistry till date. Around 80% of failures have been reported when lignocaine has been used for inferior alveolar nerve block in children and adults with irreversible pulpitis. There is a need to use newer drugs which are available which have been reported to be effective like lignocaine, such as articaine. Although articaine has been used in adults, literature supporting its use in children is sparse.
  
  
  OBJECTIVE
  The purpose of this study is to compare the anaesthetic efficacy of 4% articaine buccal infiltration and 2% lignocaine inferior alveolar nerve block in children with irreversible pulpitis. It also aims to assess the need for supplemental intrapulpal injections.
  
  
  METHODS
  This study was designed as a randomized double-blind cross over trial comparing the anaesthetic effectiveness of 4% articaine with 1:100,000 epinephrine in buccal infiltration and 2% lignocaine IAN block anaesthesia. The study subject and the pediatric dentist performing the pulpectomy procedures were blinded to the study. A sample size of 40 subjects in the age group of 5-8 y was included in the study.
  
  
  RESULTS
  The onset of anaesthesia with 4% articaine was faster as compared to 2% lignocaine. The duration of anaesthesia with articaine infiltration was shorter. The need for supplemental injection in the articaine group was less.
  
  
  CONCLUSIONS
  Four percent articaine infiltration can be used in children with irreversible pulpitis. It can be used to replace the IAN block in children thereby reducing the post anaesthetic complications like lip biting.
