Distraction osteogenesis is an important technique for the treatment of maxillofacial abnormities and defects. However, distraction osteogenesis may cause the injury of the inferior alveolar nerve. The relationship between distraction rate and nerve degeneration-regeneration shift remains poorly understood. In this study, 24 rabbits were randomly divided into four groups. To establish the rabbi...

Ameloblastoma is an infiltrative benign neoplasm in the mandible or maxilla that locally aggressive with rare metastasizing capacity. This lesion most common tumor of odontogenic epithelium. However, its occurrence children low, representing only 10–15% all reported ameloblastoma cases. In treating such neoplasms pediatric patients, preservation vital structures as inferior alveolar nerve (IAN)...

OBJECTIVES To evaluate whether age and gender differences are predictive factors for inferior alveolar nerve position with respect to mandibular first molar roots. STUDY DESIGN Cone-beam computed tomography scans [0.2-mm3 voxel size; n = 200 (100 males, 100 females)] of patients aged 15-65 years showing mandibular first and second molars were included in this study. Patients with pathoses tha...

BACKGROUND The choice of the anaesthetic modality is one of the primary steps during planning of third molar surgery. The aim of the present study was to compare the risk of developing neurological injures of the inferior alveolar nerve (IAN) and lingual nerve (LN) in patients treated for wisdom teeth removal under general anaesthesia (GA) with a group treated under local anaesthesia (LA). MA...

Onset of action and duration efficacy inferior alveolar nerve block versus single lingual subperi-osteal injection 4% articaine in mandibular second molars: A randomized clinical trial

PURPOSE Surgical removal of impacted third molars may be the most frequent procedure in oral surgery. Damage to the inferior alveolar nerve (IAN) is a typical complication of the procedure, with incidence rates reported at 1% to 22%. The aim of this study was to identify factors that lead to a higher risk of IAN impairment after surgery. MATERIALS AND METHODS In total 515 surgical third molar...

Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into...

BACKGROUND The inferior alveolar nerve (IAN) may be injured during extraction of the mandibular third molar, causing severe postoperative complications. Many methods have been described for evaluating the relative position between the mandibular third molar and the inferior alveolar canal (IAC) on panoramic radiography and computed tomography, but conventional radiography provides limited infor...

We evaluate the preoperative visualization of inferior alveolar nerve (IAN) and lingual (LN) as reported using radiation-free magnetic resonance imaging (MRI). An accurate shall minimize postoperative risk for injuries in oral maxillofacial surgery. PubMed MEDLINE, EMBASE, Biosis, Cochrane databases were selected PICOS search strategy by two reviewers medical subject headings (MeSH) terms. Thir...

Increased expression of the transient receptor potential vanilloid 1 (TRPV1) channels, following nerve injury, may facilitate the entry of QX-314 into nociceptive neurons in order to achieve effective and selective pain relief. In this study we hypothesized that the level of QX-314/capsaicin (QX-CAP)--induced blockade of nocifensive behavior could be used as an indirect in-vivo measurement of f...
