How is the lower alveolar nerve block puncture needle anesthesia restricted opening mouth to return a responsibility?

Comments and Suggestions: The inferior alveolar nerve block anesthesiologist occasionally results in restricted mouth opening when administering an intraoral injection because the injection is inaccurately placed. The anesthetic is injected into the intralar or masseter muscles (both of which control the opening and closing of the mouth, namely the rising mandibular muscle), causing the muscles to lose their ability to contract and diastole, and to remain in a contractile state (their contraction is to be in working condition, lifting the mandible, because They are the ascending mandibular muscles, which do not open the mouth), and thus are restricted in opening the mouth. Except for secondary infections (i.e., inflammation) that limit the opening of the mouth, this is usually temporary and most recover spontaneously within 2,3 hours. Oral vitamin B12 and anti-inflammatories can help.
