ABSTRACT
Controlling Pain In Pediatric Dental Patients Instills A Positive Behavior Towards Dental Treatment. This Study Was Conducted To Compare The Perceived Pain During The Injection Of Alkalinized 2% Lidocaine With Epinephrine 1:100000 Using 8.4% Sodium Bicarbonate And That Perceived During The Injection Of Conventional Lidocaine With Epinephrine 1:100000 In Pediatric Dental Patients. Twenty-five Healthy Children From Both Sexes With Age Range Of 5-9 Years Old Were Enrolled In This Study. Each Child Received Two Anesthetic Infiltration Injections On Two Separate Appointments, Once With Commercial Lidocaine With Epinephrine 1:100000 And Once With Lidocaine With Epinephrine 1:100000 Alkalinized By 8.4% Sodium Bicarbonate Solution Using Insulin Syringes By A Ratio Of 9:1. Pain Was Evaluated Using The Faces Pain Scale ? Revised By Showing The Scale To The Child After Each Injection And Asking Him/her To Choose A Face That Best Described His/her Feeling. It Was Concluded On Comparing Pain Perceived During Anesthetic Injection In Right And Left Sides Of Each Child, There Was A Statistical Significant Difference (P-value = 0.015) Between Buffered And Unbuffered Anesthesia. In Conclusion, Buffered Anesthesia Induces Less Pain Than Unbuffered Anesthesia In Children When Used In Infiltration Technique. Pain Perception Is Neither Affected By Age Nor Gender In Children.
