PURPOSE: Many dental procedures are at risk of injuring the lingual nerve. We performed this study to better elucidate the microanatomy that exists between the ipsilateral lingual and hypoglossal nerves so that iatrogenic injury can be avoided. METHODS: Adult human cadaveric tongues (ten sides) underwent Sihler's staining to identify the microanatomy between the lingual and hypoglossal nerves. RESULTS: The lingual nerve entered the middle part of the anterior two-thirds of the tongue from its lateral side and divided into two to four thick branches...

Neural stem cells (NSCs) have a high potency for differentiation to neurons and glial cells for replacement of damaged cells and paracrine effects for the regeneration and remyelination of host axons. Dental pulp is known to have a potential to differentiate into neural-like cells; therefore, dental pulp may be used as an autologous cell source for neural repair. In this study, we selectively expanded stem cells from human dental pulp in an initial culture using NSC media under xeno- and serum-free conditions...

BACKGROUND/AIMS: Intermaxillary fixation is a standard procedure for the treatment of mandibular fractures or in orthognathic surgery. Pre-drilling for screws poses the risk of accidental tooth-root injury, potentially leading to further pathological processes. Limited evidence about accidental tooth injury during intermaxillary fixation is available due to heterogenous study designs. The aim of this study was to evaluate the risk of root trauma using pre-drilled transgingival fixation screws and the clinical consequences for the affected teeth...

Platelet-rich plasma (PRP) is an autologous concentrated preparation of human platelets contained in a small volume of plasma that is characterized by hemostatic and tissue-repairing effects. Being enriched by various kinds of growth factors, and their tissue-repairing effects have made them the focus of attention for use in tissue regeneration. PRP has been safely used and documented in many different fields, including orthopedics, sports injuries, dental and periodontal surgery, and cosmetic, plastic, cardiovascular, general, and maxillofacial surgery...

Given the importance of sensory innervation in tooth vitality, the identification of signals that control nerve regeneration and the cellular events they induce is essential. Previous studies demonstrated that the complement system, a major component of innate immunity and inflammation, is activated at the injured site of human carious teeth and plays an important role in dental-pulp regeneration via interaction of the active Complement C5a fragment with pulp progenitor cells. In this study, we further determined the role of the active fragment complement C5a receptor (C5aR) in dental nerve regeneration in regards to local secretion of nerve growth factor (NGF) upon carious injury...

BACKGROUND: Mandibular fractures are common facial injuries and treatment may be complicated by post-operative infection. Risk of infection from contamination with oral flora is well established but no consensus exists regarding antibiotic prophylaxis. The purpose of this study is to assess risk factors and perioperative antibiotics on surgical site infection (SSI) rates following mandibular fracture surgery. METHODS: Retrospective medical record review was completed for trauma patients of any age surgically treated for mandibular fractures at a Level I Trauma Center from September 2006 to June 2012...

This study aimed to investigate the role of PIN1 on the hepatic differentiation of human dental pulp stem cells (hDPSCs) and its signaling pathway, as well as the potential therapeutic effects of hDPSC transplantation and PIN1 inhibition on CCl4 (carbon tetrachloride)-induced liver fibrosis in mice. The in vitro results showed that hepatic differentiation was suppressed by infection with adenovirus-PIN1 and promoted by PIN1 inhibitor juglone via the downregulation of Wnt3a and β-catenin. Compared with treatment with either hDPSC transplantation or juglone alone, the combination of hDPSCs and juglone into CCl4-injured mice significantly suppressed liver fibrosis and restored serum levels of alanine transaminase, aspartate transaminase, and ammonia...

Previous studies have demonstrated that botulinum toxin type A (BoNT-A) attenuates orofacial nociception. However, there has been no evidence of the participation of the voltage-gated sodium channels (Navs) in the antinociceptive mechanisms of BoNT-A. This study investigated the cellular mechanisms underlying the antinociceptive effects of BoNT-A in a male Sprague-Dawley rat model of trigeminal neuropathic pain produced by malpositioned dental implants. The left mandibular second molar was extracted under anesthesia, followed by a miniature dental implant placement to induce injury to the inferior alveolar nerve...

Use of imaging tools like digital C-arm, tridimensional tomography, and navigational surgery has proven its value to the surgical removal of broken needles. A 32-year-old patient was referred for evaluation of a fractured needle during inferior alveolar nerve block attempt few days before. The patient complained of a pricking sensation at the injured area while moving the neck. A contrasted computed tomography was performed for further evaluation of the needle toward the vascular network of the neck, showing a close location by the left facial artery, parallel to the styloid process of the temporal bone...

Renjith Parameswaran Nair, Changyu Zheng, Gulshan Sunavala-Dossabhoy
Normal tissues that lie within the portals of radiation are inadvertently damaged. Salivary glands are often injured during head and neck radiotherapy. Irreparable cell damage results in a chronic loss of salivary function that impairs basic oral activities, and increases the risk of oral infections and dental caries. Salivary hypofunction and its complications gravely impact a patient's comfort. Current symptomatic management of the condition is ineffective, and newer therapies to assuage the condition are needed...

Maxillofacial traumatic injuries concomitant with craniocerebral trauma are still considered as an actual problem in emergency medicine. For this category of patients one of the dangerous and severe complications is development of inflammatory process in the injured areas. Fracture lines of upper and middle facial zones pass through the accessory sinuses of the nose, maxillary/upper dental arch area and are considered to be open and infected fractures. Combination of these fractures with craniocerebral injuries and especially, with open traumas creates predisposition for development of inflammatory processes in CNS that can result in heavy outcome...

OBJECTIVES: To validate a critical-size mandibular bone defect model in miniature pigs. MATERIALS AND METHODS: Bilateral notch defects were produced in the mandible of dentally mature miniature pigs. The right mandibular defect remained untreated while the left defect received an autograft. Bone healing was evaluated by computed tomography (CT) at 4 and 16 weeks, and by micro-CT and non-decalcified histology at 16 weeks. RESULTS: In both the untreated and autograft treated groups, mineralized tissue volume was reduced significantly at 4 weeks post-surgery, but was comparable to the pre-surgery levels after 16 weeks...

Steven R Jefferies
Vital pulp therapy is the general concept involved in the "regenerative" restorative treatment of the reversibly injured dental pulp with the intention of maintaining its vitality in a restored, functioning tooth. While this procedure has been attempted with various materials and techniques over a period of several centuries, the advent of hard-setting calcium hydroxide materials in the late 1950s made the procedure of direct pulp capping a more routine and relatively predictable procedure. More recently, in the mid 1990s, a new type of water-based, "hydraulic-type," calcium silicate-based cement, mineral trioxide aggregate (MTA), was introduced to dentistry as a possible alternative to the established standard of hard-setting calcium hydroxide...

An injured patient may be the last thing dentists want to think about. However, in reality, patients can be injured during dental treatment or as the result of an incident such as a slip and fall in the office. Treatment-related injuries can run the gamut and include burns, lacerations, swallowed objects and allergic reactions, according to The Dentists Insurance Company.
