BACKGROUND: The surgical extraction of the third molar is the most frequently encountered procedure in oral and maxillofacial surgery and is related with a variety of complications. This study examined the efficacy of intentional partial odontectomy (IPO) in the third molars which have no periapical lesions and are located near important anatomical structures such as inferior alveolar nerve. METHODS: Seven patients (four males, three females, 39.1 ± 11.6 years), who received IPO to reduce the risk of inferior alveolar nerve injury (IANI), were followed long-term...

INTRODUCTION: Combat-related facial injuries involve various lesions of the mouth, the eye sockets and the facial bones. The goal of this study is to precise the particularities of these affections and their therapeutic management. METHODS: A retrospective study was performed about 56 cases of combat-related facial injuries over a period of 5 years (2010 - 2014). RESULTS: Our study included 56 male patients with an average age of 29 years (20-37)...

Tooth replacement in the anterior maxilla is most often indicated after traumatic dental injury or due to congenital missing teeth. Treatment alternatives include implant-supported restorations, conventional fixed bridges, acid-etched bridges, orthodontic space closure, or autotransplantation. Dental implants have gained increased popularity over the last 40 years. However, this treatment modality is contraindicated in patients with continuous growth of the alveolar process due to the risk of severe infrapostion of the dental implant...

BACKGROUND/AIMS: The prevalence of work-related oral trauma is underestimated because minor dental injuries are often not reported in patients with several injuries in different parts of the body. In addition, little data are available regarding their characteristics. The aim of this epidemiological study was to determine the prevalence, types and characteristics of occupational traumatic dental injuries (TDIs) in a large working community. MATERIALS AND METHODS: Work-related TDIs that occurred during the period between 2011 and 2013 in the District of Genoa (Northwest of Italy, 0...

BACKGROUND: Traumatic brain injury (TBI) is one of the major causes of mortality and disability for all ages worldwide. Mesenchymal stem cells (MSCs)-originated exosomes have provided therapeutic effects. However, as an indispensable component of MSCs, whether odontogenic stem cell-generated exosomes could benefit TBI is still unclear. Thus we aimed to explore the potential of stem cells from human exfoliated deciduous teeth-originated exosomes (SHED-Ex) for the management of TBI. METHODS: First, a transwell system was used to co-culture activated BV-2 microglia cells with SHED...

OBJECTIVE: This study aimed to identify possible associations of the presence or absence of posttrauma sequelae with the factors inherent to the traumatized tooth and treatment. MATERIALS AND METHODS: This retrospective study was performed through the evaluation of records and radiographs of a center of reference for dental trauma between January 2008 and December 2014. The factors were analyzed and associated with posttrauma sequelae, such as pulp necrosis and root resorption...

Teneurins are transmembrane proteins consisting of four paralogues (Ten-1-4), notably expressed in the central nervous system during development. All teneurins contain a bioactive peptide in their carboxyl terminal named teneurin C-terminal associated peptide (TCAP). The present study analyzed the detailed distribution of teneurin-2-like immunoreactive (Ten-2-LI) cells in developing and mature rat molar teeth, as well as in mature human dental pulps. Ten-2 and TCAP-2 genic expressions were also evaluated in rat and human dental pulps...

Dilaceration is a rare disturbance in traumatised permanent teeth, which constitutes about 3% of the injuries to developing teeth. It usually occurs as a result of trauma to the deciduous predecessors and results in non axial displacement of the already formed hard tissue portion of the developing crown. Endodontic treatment of such teeth presents a challenge to clinicians, and careful management is required to successfully address the root canal anatomy and other possible variations. The C-shaped canal configuration is most frequently seen in mandibular second molars, but this variation may also occur in mandibular first molars, mandibular third molars, maxillary molars, mandibular first premolars, and even in maxillary lateral incisors, with rare reports of such variations occurring in the maxillary central incisors...

OBJECTIVES: To determine the pulp vitality after traumatic injury, dentists often use pulp sensitivity tests, which can be ambiguous in young permanent teeth with incomplete root formation. Transmitted-light plethysmography (TLP) is a non-invasive objective method that uses a 525-nm LED to detect blood volume change in the pulp. The present study aimed (1) to investigate pulpal blood flow with TLP and optical characteristics in healthy permanent maxillary incisors in different root formation stages, and (2) to assess the influences of body growth of the children and tooth color on the TLP amplitude...

BACKGROUND: The aim of this study was to compare orthopantomography (OPG) and computed tomography (CT) accuracy in predicting inferior alveolar nerve (IAN) injury after lower wisdom teeth extraction. METHODS: Twenty-three patients with completely impacted lower third molars were enrolled in this study and OPG and CT exams were obtained before surgical intervention. Finally, a total of 26 lower third molars were extracted and cases of paresthesia following a IAN lesion have been registered...

Coronal fractures of the anterior teeth are common sequelae of traumatic dental injuries. Reattachment of fractured tooth fragments using dental adhesive techniques offers some advantages, including restoration of the function, aesthetics, shape, texture and brightness of the surface. The present report describes a clinical case of reattachment with a 4-year clinical and radiographic follow-up in a permanent maxillary central incisor with an uncomplicated crown fracture. Fragment reattachment is a conservative procedure, preserving aesthetics and functionality, and it can provide an immediate positive emotional response from the patient...
