[Anatomical rationale for lingual nerve injury prevention during mandibular block]

[Aspiration test as dental anesthesia safety criterion]

Intravascular anesthetic injection can lead to acute toxic reaction even the minimal dose of the drug was administered. The aspiration test is a generally accepted standard for local anesthesia in medicine, specially designed to reduce the risk of emergency conditions. Medical instruments should be adapted for aspiration test, the local anesthetic carpule should have a retention notch, and the dental syringe plunger need to have retention elements. The aspiration test protocol may vary. For legal protection of the doctor the aspiration test result should be described in the patient's medical record.

[Topographic study of mandibular block landmarks]

The study samples included 12 anatomical specimens taken from the fixed corpses of various gender and age. Pterygomandibular space topography was assessed by macro - and micropreparation methods. The landmarks for the universal way of mandibular anesthesia were defined associated with low risk of medial pterygoid muscle, lingual nerve, inferior alveolar neurovascular bundle damage. The study results allow increasing the efficiency and safety of anesthesia of the lower jaw teeth.
