Isolation and characterization of human periodontal ligament stem cells under the terms of use in clinical application: A pilot study.

Background: The aim of the present study is to determine the possibility of isolation and characterization of the human periodontal ligament stem cells (hPDLSCs) using limited harvested periodontal ligament (PDL) tissue of only one patient's wisdom teeth (2-4 teeth) under the more compatible terms of use in clinical application without using the fetal bovine serum (FBS).

Materials And Methods: In this pilot study, hPDLSCs were isolated from the impacted third molar, and tissue was scraped from the roots of the impacted third molar of 10 volunteers to enzymatically digest using collagenase. The cells were sub-cultured.

Effect of leukocyte and platelet-rich fibrin on free gingival graft healing: A clinical and histological study in rabbits.

Recently, the use of leukocyte- and platelet-rich fibrin (L-PRF) has been recommended due to the presence of various growth factors to increase the success of free gingival grafts (FGG). This study evaluated the effect of using L-PRF in the healing of FGG in rabbits. Twenty rabbits were randomly divided into two groups.

Efficacy of Acellular Dermal Matrix in Soft Tissue Augmentation Around Dental Implants: A Systematic Review and Meta-Analysis.

This study was done to perform a systematic review and meta-analysis of the studies on the efficacy of acellular dermal matrix (ADM) in increasing the soft tissue thickness (STT) and keratinized mucosal width (KMW) around dental implants. The PubMed, Scopus, Cochrane, Web of Science, and ProQuest databases were searched by July 2020 to retrieve relevant studies. Depending upon the heterogeneity of included studies, the weighted mean difference (WMD) with 95% CI was calculated using either fixed or random-effects model.

Comparative evaluation of microRNA-155 expression level and its correlation with tumor necrotizing factor α and interleukin 6 in patients with chronic periodontitis.

Background: MicroRNAs are a class of small noncoding ribonucleic acids that perform a critical role in adjustment of gene expression. miRNAs-155 (miR-155) participates in controlling inflammation. Periodontitis is defined as inflammatory disorder of tissues surrounding the teeth.

Effect of systemic administration of omeprazole on osseointegration around titanium dental implants: A histomorphometric study in dogs.

Background: Dental implants are widely accepted substitutes for replacing missing teeth. Many factors, including the use of specific drugs such as proton-pump inhibitors (PPIs) (omeprazole), can affect the success of dental implantations. The aim of this study was to investigate the relationship between the use of omeprazole and osseointegration of dental implants.

Comparative evaluation of the cortisol level of unstimulated saliva in patients with and without chronic periodontitis.

Background: Chronic periodontitis (CP) is one of the most prevalent diseases of the oral cavity with various biological and behavioral risk factors. We aimed to evaluate the association between the salivary cortisol level (SCL) of unstimulated saliva and CP in patients referred to Isfahan Dental Faculty.

Materials And Methods: In this analytic cross-sectional study, 90 patients were selected based on the presence of periodontitis and were divided into two groups: with periodontitis and without periodontitis ( = 45).

Evaluation of salivary calcium, phosphorus and alkaline phosphatase concentrations before and after the first phase of periodontal treatment in patients with chronic periodontitis.

Background: Evaluation of salivary biomarkers is a non-invasive, convenient, and economical method for diagnosing many diseases. Evidence shows that salivary biomarkers and periodontal disease might be correlated. This study was conducted to evaluate phase I periodontal therapy's effect on salivary concentrations of calcium, phosphorous, and alkaline phosphatase (ALP).

Relationship Between Periodontal Disease and Serum Factors in Patients Undergoing Hemodialysis.

Background: Chronic renal disease is a common condition with several recognized risk factors. Periodontal disease is a recently suggested risk factor for renal disease. We aimed to assess the relationship between periodontal disease and several serum factors in patients undergoing hemodialysis.

The effect of buccal corticotomy on accelerating orthodontic tooth movement of maxillary canine.

Background: Selective alveolar corticotomy is defined as an intentional injury to cortical bone. This technique is an effective means of accelerating orthodontic tooth movement. The aim of this study is to evaluate the effect of buccal corticotomy in accelerating maxillary canine retraction.

Evaluation of the effect of low level laser therapy toothbrush in treatment of dentin hypersensitivity.

Introduction: Dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. Recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. The purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity.

Assessment of available and stable fluoride in four widely-used toothpastes in the Iranian market.

Objective: Presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. Although the available fluoride concentration in Iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. This study was done to assess the fluoride ion concentration and stability in four widely used dentifrices in Iran.

Socket preservation using demineralized freezed dried bone allograft with and without plasma rich in growth factor: A canine study.

Background: The accelerating effect of plasma rich in growth factors (PRGFs) in the healing of extraction sockets has been demonstrated by some studies. The aim of the present study was to histologically and histomorphometrically evaluate whether bone formation would increase by the combined use of PRGF and demineralized freeze-dried bone allograft (DFDBA).

Materials And Methods: In four female dogs, the distal root of the second, third and fourth lower premolars were extracted bilaterally and the mesial roots were preserved.

Effect of enamel matrix derivative on bone formation around intraosseous titanium implant: An experimental study in canine model.

Background: The purpose of this study was to perform a histological, histomorphometrical, and immunohistochemical evaluation of the effect of Enamel matrix derivative (EMD) on bone formation around titanium dental implant.

Materials And Methods: In this animal study, 12 implants (10 × 3.8 mm) were inserted in the tibia bone of three dogs of Iranian breed.

Comparison of fibronectin in human marginal gingiva and interdental papilla using immunohistochemistry.

Background: The differences between marginal gingiva and interdental papilla may be due to variation in the molecular composition of these two different anatomical structures. The aim of this study was to evaluate the staining intensity of fibronectin in human marginal gingiva and interdental papilla.

Materials And Methods: In a prospective analytical study, 16 healthy subjects needing crown lengthening surgery were selected.
