Introduction: The degree or level of deflection of the dental needle, in most cases, can determine the success or failure of the dental anesthesia technique.
Objective: measure the degree of deflection of the dental needle, comparing 5 different brands available in the city of Hermosillo, Sonora, Mexico.
Method: An experimental study was carried out, with a model created with a professional level and a carpul syringe, various punctures were made in a piece of beef, simulating the performance of a linear technique of oral anesthesia. Periapical radiographs of each of the punctures were taken, and with the help of a millimeter mesh, measurements were made. Within each group of needles, different deflection measures were presented, and an average of each brand was obtained. The range ranged from .65 mm to 2.1 mm of deflection, taking as reference a straight plane.
Conclusions: It was shown that the Septodont® brand was the one that presented the lowest puncture deflection. It is advisable to verify and examine the condition of the needles before being used to perform surgical procedures, and thus reduce risks and / or postoperative complications.
