title: Comparative Evaluation of Mental Incisal Nerve Block, Inferior Alveolar Nerve Block, and Their Combination on the Anesthetic Success Rate in Symptomatic Mandibular Premolars: A Randomized Double-blind Clinical Trial.
abstract: BACKGROUND
  The purpose of this study was to compare the effectiveness of mental incisive nerve block (MINB) and inferior alveolar nerve block (IANB) that were given alone or in combination to provide anesthesia to symptomatic mandibular premolars.
  
  
  METHODS
  One hundred fifty-three patients participated in this randomized, double-blind clinical trial. The patients were divided into 3 groups; first group received MINB with 2 mL 2% lidocaine with 1:200,000 epinephrine and a mock IANB with 2 mL sterile saline, patients in group 2 received mock MINB and an IANB with 2 mL 2% lidocaine, and patients in group 3 received both MINB and IANB with 2 mL each of 2% lidocaine. Access cavity preparation was initiated after 10 minutes. Success was defined as no pain or faint/weak/mild pain during endodontic access preparation and instrumentation. The anesthetic success rates were analyzed with Pearson χ(2) test at 5% significance levels.
  
  
  RESULTS
  The MINB and IANB gave 53% and 47% anesthetic success rates, respectively, with no significant difference between them. Adding an IANB to MINB significantly improved the success rates to 82%.
  
  
  CONCLUSIONS
  A combination of MINB and IANB can provide improved local anesthesia for symptomatic mandibular premolars.
