a 39-year-old iranian female patient who was a known case of primary cervical dystonia since 10 years ago presented to a private office for dysport injection. the patients experienced severe dysphagia after inferior alveolar nerve block which was preceded by cervical botolinum toxin injection. a possible synergistic effect of botolinum toxin and lidocaine to produce severe dysphagia is presente...

The mental foramen is located in a position where certain dental procedures may cause inadvertent damage to the nerve and lead disorders of sensory functions such as altered sensa¬tion, complete numbness, neuropathic pain, which are uncommon but severe treatment complications with significant medico-legal implications. Hence thorough knowledge its anatomical relation surrounding structures crit...

Local anaesthesia makes the patient and dentist comfortable to do treatment with least amount of discomfort, but dental patient’s most frequent fear is receiving local anaesthetic injections. The present study attempted evaluate compare perception pain, pressure discomfort induced by three types injections (Infiltration, mental nerve block inferior alveolar injection) for mandibular anaesthesia...

Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or men...

Abstract Objectives: It is important to know the exact location and anatomic variety of inferior alveolar nerve canal for different procedures of mandibular surgeries. The aim of the present study was to evaluate inferior mandibular canal’s anatomic position by Cone-beam Computed Tomography (CBCT). Methods: In a cross sectional study, CBCT were taken and assessed from 130 patients (...

Purpose: The objectives of this study were to determine the likelihood of regaining functional sensory recovery (FSR) after microsurgical repair of the inferior alveolar nerve (IAN), and which variables significantly affected the outcome of that surgery in a large series of patients. Materials and Methods: This was a retrospective cohort study that evaluated all patients who had undergone micro...

OBJECTIVES To investigate the effect of persistent neurosensory disturbance of the lingual nerve (LN) or inferior alveolar nerve (IAN) on general health and oral health- related quality of life (QoL). METHODS The study design was a case-control study. Patients with persistent neurosensory deficit of LN or IAN after lower third molar surgery (for 12 months or more) were the study group. The co...

PURPOSE Osseointegrated implants lack a periodontal ligament. Nevertheless, masticatory function in subjects with implant-supported restorations appears similar to function in those with natural dentition. It is not clear how the neurophysiologic mechanisms that modulate jaw movement are associated with osseointegrated implants. This study examined the output from the inferior alveolar nerve du...
