BACKGROUND: Arthrocentesis has an effect of washing out inflammatory products that accumulate in the joint compartment of a dysfunctional TMJ. The procedure removes inflammatory cytokines, which are pain-causing substances, for early reduction of TMJ pain and quick recovery of jaw function, thus increasing the possibility of a successful rehabilitation. OBJECTIVE: The aim of the present study was to investigate the relationship between arthroscopy synovitis grade in patients with unilateral high condylar fractures and concentrations of the pro-inflammatory cytokines tumor necrosis factor (TNF)-alpha as well as of matrix metalloproteinases (MMPs) in washed-out synovial fluid (SF) samples obtained from those patients...

The aim of this paper is to report two cases of sternal dislocation (SD) in cats and the long-term outcomes with and without surgery. In a cat with poly-traumatized SD (Case 1), mandibular, radial, and ulnar fractures were corrected first, and the SD was allowed to heal without intervention for 14 months. However, normal healing did not occur and sternal instability remained. Therefore, the SD was corrected surgically, and the cat recovered fully within 4 weeks. In a cat with isolated SD (Case 2), surgery was performed, and normal posture and gait were regained after 5 weeks...

Introduction: The circumferential 2 mm ferrule during the fabrication of the crown is strongly advocated for the long-term clinical success. During the routine clinical practice, the dentist encounters the endodontically treated tooth (ETT) with inadequacy of the ferrule in some segment due to caries, abrasion, and erosions. The aim of this in vitro study was to investigate the consequence of inadequate segmental ferrule location on fracture strength of the root canal-treated anterior and posterior teeth...

Facial fracture management dates as early as Hippocratic era. Comminuted mandibular fractures are one of the challenging clinical condition requiring high surgical expertise to achieve a good functional and esthetic outcome. In presence of infection and other facial fractures managing comminuted mandibular fracture becomes more challenging. Here we present a case of grossly comminuted and infected mandibular fracture with delayed presentation managed by using maxillary distractor as stabilizing agent. Using a maxillary distractor for managing a fractured mandible has been seldom reported in literature...

A series of surgical cases operated in our unit are considered to analyze and evaluate the different techniques and sequencing employed in the surgical management of double/triple mandibular fractures involving a condylar fracture. Deviating from the normal sequence of reducing and fixing the dentate segment first, we addressed the condylar segment first. A combination of different approaches for different cases such as a periangular with a vestibular, a preauricular and a retromandibular with a vestibular were used according to the type of fractures...

Introduction  Mandibular fractures represent a high percentage of all facial fractures, and the bite force is a fundamental parameter to measure the actual mandibular function and, subsequently, the masticatory efficiency and quality of life. Objectives  The purpose of the present systematic review was to verify if there is any difference in the bite forces of patients with mandibular fractures fixed by locking or non-locking plates, testing the null hypothesis of no difference in this parameter. Data Synthesis  A systematic review of the literature was conducted using four databases (PubMed, Virtual Health Library, Web of Science and Science Direct) without restrictions as to publication date or language...
