Plasma Levels of Magnesium, Calcium, Calcium to Magnesium Ratio, and Associations with Metabolic Syndrome and Cardiometabolic Risk Factors.

Magnesium and calcium are elements that have been associated with cardiometabolic risk factors related to metabolic syndrome (MetS). However, there are gaps in the knowledge regarding the impact of the calcium to magnesium (Ca/Mg) ratio in plasma. Thus, we aim to evaluate the associations between magnesium and calcium levels in plasma, and the Ca/Mg ratio in plasma with MetS components and other cardiometabolic risk factors.

Systemic Use of Antibiotics in Dental Implant Surgeries in Immunocompetent Patients: A Blind Randomized Controlled Trial.

Purpose: To evaluate two pharmacologic antibiotic prophylaxis regimens and a control group of immunocompetent patients undergoing two-stage dental implant placement in a triple-blind randomized controlled clinical trial.

Materials And Methods: From a group of 61 immunocompetent patients, 21 were randomly allocated into group 1 (G1) without antibiotic prophylaxis (control), 20 in group 2 (G2) with preoperative antibiotic prophylaxis (1 g amoxicillin 1 hour before the procedure), and 20 in group 3 (G3) with preoperative (1 g amoxicillin) and postoperative (500 mg every 8 hours for 5 days) antibiotic prophylaxis. Pain was assessed with the visual analog scale (VAS) and by considering the number of painkillers patients used.

BMP-2 and Noggin Immunoexpression in Ameloblastomas, Odontogenic Keratocysts, and Dentigerous Cysts.

BMP-2 and Noggin are expressed in several tissues and participate in cell differentiation and proliferation during odontogenesis and tumor development. We evaluated the immunohistochemical expression of these proteins in ameloblastomas (AMs), odontogenic keratocysts (OKCs), and dentigerous cysts (DCs). The expression in AM (n.

Lack of Association between Inadequate Micronutrient Intake and Prognosis in Outpatients with Heart Failure.

Inadequate nutrient intake can lead to worse outcomes in patients with heart failure (HF). This prospective cohort study aimed to assess the prevalence of inadequate micronutrient intake and their association with prognosis in 121 adult and elderly outpatients with HF. Habitual micronutrient intake was evaluated using 24-h dietary recalls (minimum 2 and maximum 6).

Influence of the mandibular plane and magnitude of the movement in sagittal split ramus osteotomy: an in vitro study.

Purpose: The aim of this study was to evaluate fixation resistance in mandibular sagittal split ramus osteotomy in standardized polyurethane hemimandibles with two types of advancement (6 and 12 mm), with or without mandibular plane rotation, using a 2.0-mm plate/screw system.

Methods: Seven groups were evaluated using a vertical compressive load in the first molar region, and the applied force in Newtons was recorded in 1 mm, 5 mm, and 10 mm displacements, as well as the maximum force.

Immunohistochemical comparative analysis of IMP-3 and KI-67 in actinic cheilitis and lower lip squamous cell carcinoma.

Actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC) exhibit epithelial alterations mainly associated with chronic ultraviolet ray exposure. Currently, it is impossible to predict which AC cases will progress to LLSCC; thus, biomolecular markers have been studied. The aim of this study was to evaluate the immunoexpression of IMP-3 and KI-67 in AC and LLSCC.

Immunohistochemical expression of OCT4 and CD44 in major and minor salivary gland neoplasms.

The aim of this study was to identify tumor parenchyma cells exhibiting immunohistochemical profile of stem cells by evaluating the immunoreactivity of OCT4 and CD44 in a number of cases of salivary gland neoplasms. The sample consisted of 20 pleomorphic adenomas, 20 mucoepidermoid carcinomas, and 20 adenoid cystic carcinomas located in major and minor salivary glands. The expression of OCT4 and CD44 was evaluated by the percentage of positive cells and the intensity of expression.

A Cross-Sectional Analysis on Factors Associated With Peri-Implant Pathologies at the Implant Level.

Pathologies in peri-implant tissues are common and may disturb long-term implant supported rehabilitation. We aimed to evaluate the occurrence of such peri-implant diseases and their associated factors in this study. Peri-implantitis and mucositis were diagnosed based on clinical and radiological findings.

Expression of urokinase-type plasminogen activator and its receptor in squamous cell carcinoma of the oral tongue.

Urokinase-type plasminogen activator (uPA) and its receptor (uPAR) act in the proteolysis of basement membrane and extracellular matrix structures, facilitating tumor invasion. The purpose of this study was to evaluate the relationship between these proteins and clinicopathological parameters in squamous cell carcinoma of the oral tongue (SCCOT). Sixty cases of SCCOT were submitted to immunohistochemistry and analyzed semiquantitatively at the invasion front and in the tumor core.

Recurrent aphthous ulceration: an epidemiological study of etiological factors, treatment and differential diagnosis.

Background: Recurrent aphthous ulcerations are common benign ulcerated lesions on the mouth, whose etiology is poorly understood, with controversial treatment and difficult to control in clinical practice.

Objective: To evaluate the cases of recurrent aphthous ulcerations with a focus on treatment, diagnosis and etiology.

Methods: This is a retrospective study of the cases of the Oral Diagnosis service of the Rio Grande do Norte Federal University in Natal/RN.

Evaluation of laser therapy and alpha-lipoic acid for the treatment of burning mouth syndrome: a randomized clinical trial.

The aim of this study was to evaluate the efficacy of low-level laser therapy (LLLT) and alpha-lipoic acid (ALA) in the treatment of burning mouth syndrome (BMS) and secondary oral burning (SOB) by unstimulated sialometry, symptom assessment, and measurement of salivary TNF-α levels. Forty-four patients were randomized into four treatment groups: BMS/laser (n = 10), BMS/ALA (n = 5), SOB/laser (n = 15), and SOB/ALA (n = 14). The control group consisted of eight healthy female subjects.

Material And Methods: A prospective study was carried out in the period from December 2013 to January 2016 targeting all attended cases in that period. For statistical analysis, Pearson chi-square and Fisher tests were used to verify association and ANOVA and Student's t tests to test for significant difference, p was defined as ≤0.

An Evaluation of the Efficacy of Local Hemostatic Measures in Dental Patients Taking Oral Anticoagulants: A Critical Review of the Literature Over the Past Two Decades.

The increased risk of bleeding observed in patients on oral anticoagulant therapy (OAT) undergoing outpatient oral surgical procedures has been reported in the literature and remains a major concern in the care of these patients. This is still of great concern to dental surgeons that discontinuing OAT medication increases the risk of thromboembolism, while maintaining the therapeutic dose increases the risk of hemorrhage. Several local hemostatic measures have been used to control bleeding in patients on OAT.
