The authors conducted a clinical-trial, uncontrolled study to determine infraorbital nerve block effectiveness.. Nineteen adult volunteers received 1. Researchers used an electric pulp tester to measure pulp anesthesia in maxillary incisors and premolars. Participants reported soft tissue anesthesia and discomfort during the injection procedure; anesthesia onset time and its duration were also assessed and analyzed.
Authors evaluated pain perception when injecting anesthesia with a visual analogue scale VAS , finding that When assessing anesthesia success, it was observed that a greater number of canine teeth and first premolars The authors also observed a significant greater number of non-response non-anesthetized cases in central and lateral incisors Anesthesia onset was at 12 to 19 minutes, with canines exhibiting the largest number of anesthetized reports with Infraorbital anesthesia technique achieved successful anesthesia in only This was demonstrated after these teeth were evaluated using rigorous pulp vitality testing.
Soft tissue anesthesia occurred and it was classified as uncomfortable. Authors consider that usefulness of infraorbital nerve block technique in dentistry was questionable..
Diecinueve adultos voluntarios recibieron 1. Many authors have reported and described that intraoral infraorbital nerve block is effective to provide deep anesthesia in upper front incisors and premolars.
In conclusion, it can be said that the intraoral infraorbital nerve block will rarely allow diffusion of anesthetic solution to the upper-anterior alveolar nerve; therefore, anesthetic success is not guaranteed. The research team reported that anesthesia obtained with intraoral infraorbital nerve block technique was ineffective in providing deep pulpal anesthesia in central and lateral incisors, and first molars.
