title: Making Nasopalatine Blocks Comfortable: A Randomised Prospective Clinical Comparison of Pain Associated with the Injection Using an Insulin Syringe and a Standard Disposable 3 mL Syringe.
abstract: OBJECTIVE
  This study was conducted to compare and evaluate the pain associated with administration of Nasopalatine blocks using a disposable insulin syringe and the conventional disposable 3 mL syringe.
  
  
  METHODS
  Forty patients requiring intraalveolar extractions of maxillary central incisors were randomly assigned to two groups of 20 patients each; one (Group A) received the nasopalatine block with a standard 3mL syringe and the other (Group B) received the block with an insulin syringe. Patients were asked to rate the pain associated with the injection on a visual analog scale (VAS) and the results were analysed using a Chi Square Test.
  
  
  RESULTS
  The mean VAS score for Group A and B was 1.55 and 1 respectively. Chi Square value was calculated to be 8.603 (degree of freedom= 3, P value= 0.0351). There were no differences in the effectiveness of anesthesia between the groups.
  
  
  CONCLUSIONS
  Pain associated with administration of the nasopalatine blocks may be significantly mitigated by using the Insulin syringe.
