Comparison of Pain Levels between Infraorbital Nerve Block with and without Greater Palatine Anaesthesia during Orthodontic Extraction: A Split-mouth, Prospective Study ZC14-ZC17
SGT University, Gurgaon, Haryana, India.
Introduction: Pain free dentistry is the need of the hour, and when our dental procedure involves treatment specially in children then it is of prime concern. Even after introduction of latest pain control measures, greater palatine nerve block injection is still considered a painful experience in most of the patients due to firm adherence of palatal mucosa to the underlying bone.
Aim: To evaluate the pain levels between Infraobital nerve block with and without Greater Palatine (GP) anaesthesia during orthodontic extraction of maxillary first premolar.
Materials and Methods: This Split-Mouth, Prospective Study was conducted from November 2019 to January 2020 on 60 patients with age group range from 12-18 years requiring bilateral maxillary first premolar extractions for orthodontic purpose. Each patient received 1.8 mL of lignocaine HydroChloride (lignocaine HCl) for infraorbital nerve block on 1 side and on the other side received 0.5 mL lignocaine HCl for greater palatine nerve block in addition to 1.8 mL lignocaine HCl for infraorbital nerve block. The nerve block were given based on a computer-generated list. In each patient, difference in the pain levels was assessed on administration of infraorbital nerve block with and without greater palatine nerve block.
Results: There was no statistically significant difference in pain levels between Orthodontic extraction of maxillary first premolar extraction with and without palatal injection (p>0.05).
Conclusion: Orthodontic extraction of maxillary first premolar teeth can be done by giving only infraorbital nerve block with 2% lignocaine without greater palatine nerve block.
