title: Estimated beginning time of local anesthesia effectiveness in forced cold air application: A preliminary study.
abstract: BACKGROUND
  The literature has reported that forced cold air anesthesia decreases the discomfort effect of various laser therapies. The aim of this preliminary study was to determine the average beginning time of the local anesthetic effect of the forced cold air application when it is applied to all body surfaces except the face.
  
  
  METHODS
  A total of 52 participants (26 females and 26 males) were included in this study. During application of the forced cold air, the beginning time of local anesthesia effectiveness for each volunteer was determined by giving painful stimuli. The results were then analyzed statistically.
  
  
  RESULTS
  The mean beginning time value of the local anesthesia was 52.88 (ranging between 30 and 60) seconds in the female group and 56.34 (ranging between 30 and 60) seconds in the male group. The mean beginning time value of the local anesthesia was 54.61 (ranging between 30 and 60) seconds in both genders. There was no statistical difference between the two groups (Z = - 0.834, p = 0.404).
  
  
  CONCLUSIONS
  Forced cold air anesthesia-which is a quick, safe, cost-effective, and practical local anesthesia method-seems to be useful and effective when used alone in laser treatment.
