Abstract

Introduction: to ensure the effectiveness and safety of conduction anesthesia in the lower jaw, it is necessary to take into account not only the pharmacological features of the local anesthetic, the trajectory of the needle, but also the variant anatomy of the mandible, the configuration of which will determine the choice of the target point and the local anesthesia technique. In this regard, we conducted a study to study the variant anatomy and morphometric characteristics of the lower jaw branch and their processes.
Materials and methods.
The sample included 27 certified human heads (16 males and 11 females). Measurements were taken on the skeletonized preparation using a caliper, a depth gauge, and an electronic goniometer. The following parameters were analyzed: shape of the lower jaw, distance between the lateral clivus of the condylar processes, distance between the medial clivus of the condylar processes, thickness of the base of the condylar processes, height of the condylar processes, length of the base of the condylar processes, shape of the condylar processes, the width of the condylar processes in transverse and sagittal section, the angle of the jaw branch, the angle of the condylo-coronoid line, the angle of the coronoid process, the depth of the notch of the lower jaw. Results and discussion. The study of the mandible showed individual and sexual differences in its structure. In many ways, there was a difference depending on the parties studied. At the same time, there was no statistically significant difference in any parameter depending on the side of measurement. However, all the parameters studied differed by gender. Thus, men had a large angular width (p=0.004), the height of the branch (p=0.003), the distance between the lateral (p=0.002) and medial (p=0.007) slopes of the condylar processes, the width of the condylar processes in cross section (p=0.036). Therefore, men on average had larger morphometric indicators of the lower jaw.
Conclusion.
The presented data will help the dentist to more accurately determine the projection of conducting conduction anesthesia depending on the morphometric characteristics of the lower jaw. It was also noted that most of the parameters can be determined in vivo through radiation diagnostics and anthropometry.
