Nasal Septal Deviation After Surgically Assisted Rapid Maxillary Expansion.

Background And Aim: Surgically assisted rapid maxillary expansion (SARME) is a surgical technique widely used to correct deficiency of the transverse maxillary dimension. Although some studies investigated the effect of SARME on nasal and facial alterations, there is no evidence that correlates nasal septal deviation (NSD) to SARME as a possible postoperative sequel. The aim of this study is to address and quantify possible variations in the position of the nasal bony septum after SARME and identify any NSD as a postoperative outcome of this surgical technique.

Leukotriene receptor antagonist reduces inflammation and alveolar bone loss in a rat model of experimental periodontitis.

Background: Leukotrienes (LTs) participate in the process of tissue damage in periodontal disease by leukocyte chemotaxis and osteoclastic activation. The activation of Cysteinyl-LT receptor is associated with increased expression of proinflammatory molecules and osteoclastogenesis. However, its implications on periodontal disease progression have not been studied.

Tricalcium silicate-based cements: properties and modifications.

Mineral trioxide aggregate (MTA) has been widely used for different reparative procedures in endodontics. The extensive use of this cement for pulp capping, apexifications, apical surgeries, and revascularization is related to its ability to induce tissue repair and to stimulate mineralization. Several research studies have tested modifications in the composition of MTA-based cements in order to enhance their clinical performance.

Maxillary osteomyelitis associated with osteopetrosis: Systematic review.

Osteopetrosis is a rare condition which presents increased bone density and deficient bone remodeling. The consequential complications include cranial nerve impairment due compression, bone fractures, and osteomyelitis. Maxillary osteomyelitis is uncommon even in osteopetrosis patients.

Lipoma on the Lower Lip.

Lipoma is a benign tumor of fat tissue, found frequently in subcutaneous tissues. However, oral manifestations are relatively rare. The present patient illustrates the successful treatment of a lipoma treated by complete excision of the lesion.

Adhesives based on butyl-cyanoacrylate for fixation of autologous bone graft: Pilot study in rabbits.

Background/aim: Injuries to bone during trauma may require bone grafts and/or fixation to ensure optimal healing. Autologous bone grafts are still very common, but little data exist regarding the most effective means of fixation of such grafts. The aim of this study was to compare the fixation of autologous bone grafts with titanium screws and adhesives based on n-butyl-cyanoacrylate.

Treatment of mandibular condyle fractures. A 20-year review.

Background/aim: The condylar fracture is among the most frequent facial fractures. Despite all the published studies, its treatment remains controversial. The aim of this retrospective study was to evaluate the epidemiology and complications of mandibular condyle fractures managed by surgical and conservative treatments, over a period of twenty years.

Mandibular angle fractures: a comparative study between one- and two-plate fixation.

Background/aim: The mandibular angle fracture is a challenging fracture to manage. Over time, the literature has shown many types of treatment modalities and different kinds of internal fixation. The aim of this study was to evaluate the outcomes and complications of mandibular angle fractures managed by Champy's technique and two-plate fixation, over a period of 20 years.

Evaluation of Three Different Osteosynthesis Methods for Mandibular Angle Fractures: Vertical Load Test.

The aim of this study was to evaluate the mechanical behavior of different rigid fixation methods in mandible angle fractures. Three different plates were tested: one 4-hole grid miniplate, one 8-hole curved grid miniplate, and one 4-hole straight miniplate.For the loading tests, 30 polyurethane hemimandibles sectioned at the angle area to simulate a simple angle fracture were used: 10 hemimandibles for each group.

Mucoepidermoid Carcinoma of the Hard Palate in a Young Patient.

Carcinomas of salivary glands are rare and can affect major or minor salivary glands. Among them, the mucoepidermoid carcinoma is the most prevalent and its occurrence in the first 2 decades of life is highly unusual. Their common clinical aspect to different diseases is a challenge in diagnosis.

Sixteen patients were studied (mean age 31±7.

The long-term administration of calcineurin inhibitors decreases antioxidant enzyme activity in the rat parotid and submandibular salivary glands.

Aims: Calcineurin inhibitors are widely used for prevention of graft rejection and treatment of autoimmune disorders, which result in increased longevity and enhanced quality of life for patients. Unfortunately, the toxic side effects of these drugs (mainly renal, hepatic and cardiac) limit their use. In this work, we studied the effects of long-term treatment of rats with the immunosuppressant cyclosporin (CsA) or tacrolimus (Tac) on salivation, saliva composition and on the major salivary glands (parotid and submandibular) in terms of histological alterations and oxidative stress, evaluated as lipoperoxidation (thiobarbituric acid reactive species--TBARS) and antioxidant enzyme activity contents (superoxide dismutase--SOD, catalase--CAT and glutathione peroxidase--GPx).

In vitro biomechanical comparison of six different fixation methods following 5-mm sagittal split advancement osteotomies.

The aim of this study was to compare the mechanical stability of six methods of rigid fixation in SSRO using a biomechanical test model.
