The aim of this study is to investigate substance P (SP) expression in rat periodontal alveolar bone after inferior alveolar nerve transection. 60 male Wistar rats were divided into six groups randomly. Mandibular alveolar bones were removed from the denervated rats according to sacrifice time points (0, 3, 7, 14, 21, and 28 days after operation). Immunohistochemical staining was applied to tra...

Objective: Trigeminal nerve injury is an uncommon complication of outpatient oral surgery and dental procedures such as removal impacted teeth, placement endosseous implants, even injection local anesthesia. In the field maxillofacial surgery, two most commonly injured branches trigeminal are inferior alveolar lingual nerves. Fortunately, injuries will undergo spontaneous recovery, with only a ...

Introduction Pain control is one of the most important aspects of behavior management in children. The most common way to achieve pain control is by using local anesthetics (LA). Many studies describe that the buccal nerve innervates the buccal gingiva and mucosa of the mandible for a variable extent from the vicinity of the lower third molar to the lower canine. Regarding the importance of app...

Neurological complications following the administration of a local anaesthetic can be alarming. By reading reports of such incidents, dentists who find themselves in similar situations will be able to reassure their patients and act accordingly. The authors have reviewed the literature for those neurological complications that have been reported and offer an explanation of their aetiology. Exam...

Numb chin syndrome reflects an abnormality in the mental nerve or inferior alveolar nerve, or occasionally in a nervous structure located higher up in the body. It manifests as objective and/or subjective sensory disorders in the distribution of the mental nerve or inferior alveolar nerve, represented primarily by half of the lower lip and chin. Although numb chin syndrome falls mainly within t...

Background and Objectives: Split sagittal osteotomy is a common operation that may induce inferior alveolar nerve (IAN) damage, potentially leading to sensory deficit, numbness, and pain. Investigations in Iran to evaluate the adverse effects of sagittal split osteotomy surgery are rare so questions have been raised about the success rate of operatio...

Squamous cell carcinoma showed perineural spread along the inferior alveolar nerve. Key CT features of this spread were foramen enlargement, resurfacing of tumor, and asymmetry of fat spaces.
