| Summary: | The comparative analysis of dental needle tip deformation after periodontal anesthesia for the increasing it safety was carried out. Methods. 47 needles with «a standard bevel» and a bevel like «surgical bevel» are selected after periodontal ligament and intraseptal anesthesia in 24 patient with tooth extraction. In a view under microscope deformation of needles tips were observed. Results. In all cases of periodontal anesthesia the deformation of the tips looked like a bends under various angle. Bends from 15° to 180° to needle axis are noted. Discussion. These deformations arise at single use of a needle. After anesthesia of multiroot teeth where injections were carried out from two to four sides of the tooth, needle tip deformations are also revealed, while single using the deformed needles did not apear to differ between them. Therefore for one periodontal injection - one needle is necessary, and in cases of multiroot teeth 2-4 needles are needed. The smallest deformation was observed in needles «surgical edge» type that is associated with a smaller length of a bevel and its two-edged sharpening. |
