In Vitro Effects of Photobiomodulation with 660 Nm Laser and Vitamin D on Osteoblastic Differentiation of Human Periodontal Ligament Stem Cells.

Background: Mesenchymal stem cells (MSCs) can be found inside the human periodontal ligament. Application of vitamin D and photobiomodulation for regulation of the proliferation of MSCs and bone differentiation have been recently considered in cell engineering. This study is performed to evaluate the effects of photobiomodulation with 660 nm laser exposure and vitamin D on human periodontal ligament stem cells (HPDLSCs) and their osteoblastic differentiation properties.

The Effect of Low-Level Laser Therapy in Combination with Leukocyte- and Platelet- Rich Fibrin on Bone Regeneration in Rabbits' Calvarial Defects: Histologic and Histomorphometric Studies.

Objective: Bone regeneration is a desired treatment outcome in implant dentistry. The primary goal of the current investigation was to assess the joint effect of low-level laser therapy (LLLT) and leukocyte- and platelet-rich fibrin (PRF) on new bone formation.

Materials And Methods: During this experiment study, forty bone defects (8 mm in diameter) were generated in the calvaria of ten New-Zealand white rabbits.

Effect of Green Tea on the Level of Salivary Interleukin-1 Beta in Patients with Chronic Periodontitis: A Randomized Clinical Trial.

Aim: Interleukin-1 beta (IL-1) is one of the major biomarkers involved in the pathogenesis of chronic periodontitis. The aim of this study was to evaluate the changes in salivary IL-1 concentration in patients with chronic periodontitis following daily consumption of green tea.

Methods And Materials: Thirty patients with an average age of 45.

Evaluation of NLRP3 and IL-18 Levels after Periodontal Therapy.

The progression of periodontitis depends on interactions between the periodontal pathogens and the host immune cytokines, including interleukin (IL)-1β and IL-18. Production of IL-1β is regulated by NOD-like receptors family pyrin domain containing 3 (NLRP3). This study aimed to evaluate the effect of periodontal treatment on the concentrations of IL-18 and NLRP3 in patients with chronic periodontitis.

Fabrication and characterization of collagen-hydroxyapatite-based composite scaffolds containing doxycycline via freeze-casting method for bone tissue engineering.

In this study, hydroxyapatite nanoparticles containing 10% doxycycline, a structural isomer of tetracycline, was prepared by the co-precipitation method. It was added to collagen solution for the preparation of the scaffold with freeze-casting method in order to develop a composite scaffold with both antibacterial and osteoinductive properties for repairing bone defects. The scaffolds were evaluated regarding their morphology, porosity, degradation and cellular response.

The Effect of Diabetes Mellitus Type I on Periodontal and Dental Status.

Introduction: Diabetes mellitus type I is a chronic metabolic disease with an autoimmune origin. The initial manifestations mainly appear during childhood and its prevalence is on the rise in many countries. Some of the complications of diabetes mellitus are problems related to oro-dental structures and periodontal diseases.

Prevalence and location of the posterior superior alveolar artery using cone-beam computed tomography.

Purpose: Insufficient knowledge of the anatomy of the maxillary sinuses prior to sinus graft surgery may lead to perioperative or postoperative complications. This study sought to characterize the position of the posterior superior alveolar artery (PSAA) within the maxillary sinuses using cone-beam computed tomography (CBCT).

Materials And Methods: A total of 300 patients with edentulous posterior maxillae, including 138 females and 162 males with an age range of 33-86 years, who presented to a radiology clinic between 2013 and 2015 were enrolled in this retrospective cross-sectional study.

Prevalence, Location, and Size of Maxillary Sinus Septa: Computed Tomography Scan Analysis.

Introduction: The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT).

Materials And Methods: In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann-Whitney tests were used for the analysis of data.

Mast Cell Concentrations in Peripheral and Central Giant Cell Granulomas: Is there any Angiogenetic Role?

Background: In the maxillofacial region, giant cell granulomas occur in 2 clinical forms, central and peripheral. Despite histopathological similarity between these 2 forms totally different clinical behaviors have been reported. The present study was undertaken to compare mast cell and vascular concentrations in these pathologic lesions.

Comparison of periodontal ligament injection and inferior alveolar nerve block in mandibular primary molars pulpotomy: a randomized control trial.

Background: Inferior alveolar nerve block is a common technique for anesthesia of the primary mandibular molars. A number of disadvantages have been shown to be associated with this technique. Periodontal ligament (PDL) injection could be considered as an alternative to inferior alveolar nerve block.

Oral health related quality of life in diabetic patients.

Background and aims. Diabetic patients display an increased risk of oral disorders, and oral health related quality of life (OHRQL) might affect their management and treatment modalities. The aim of the present study was to determine OHRQL and associated parameters in patients with diabetes.

Association between chronic periodontitis and serum lipid levels.

Regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. The historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subjects as control group. Both groups had the same age and weight ranges, sex, and diet, without any periodontal treatment history in the past six months, underling systemic disease such as diabetes, anti-hyperlipidemic drugs or active tobacco smoking history.
