In this study, we aimed assess the genotoxicity and cytotoxicity effects of CBCT dental examinations at two different fields view (FOVs) in exfoliated buccal epithelial cells.Sixty healthy adults participated current study. They were divided into identical groups; with FOV 6*6 cm2 8*11 cm2. Exfoliated oral mucosa cells...

The decellularized human amniotic membrane (dHAM) emerges as a viable 3D scaffold for organ repair and replacement using tissue engineering strategy. Glutaraldehyde (GTA) 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) can increase the biomechanical properties of dHAM. However, crosslinking process is associated with biochemical changes residual toxic materials, dampening biocompatibility From histologic point view, each side biologically different. While dHAM basement rich in growth...

An ideal endodontic sealer should bond to both dentin and root-filling material. This study aimed assess the push-out strength (PBS) of mineral trioxide aggregate (MTA)-Fillapex, Endoseal MTA, AH26, Sure-Seal Root root after canal drying with different techniques.

Background: The most common type of oral cancer is squamous cell carcinoma. If it diagnosed in the earlystages; success treatment can be increased. It seems that ELISA-based techniques as a screening tool forsociety are cost-effective methods for early diagnosis. CD44 key marker detection SCC stemcells. aim this study was to compare level soluble saliva and serum between patients with oralSCC healthy controls. Materials Methods: Saliva were collected from 20 primaryOSCC persons control...

Considering to the possibility of cellular and genetic damage by implant materials in patient clinician, safety biomaterials should be evaluated. The purpose this study was compare cytotoxicity genotoxicity induced two nanocomposites, hydroxyapatite/bioactive glass (HA/BG) fluorapatite/bioactive (FA/BG) vitro. Biomaterial extracts (BMEX, 100%) were prepared incubating 100 mg/mL each biomaterial powder complete culture medium (RPMI1640 + 10% FBS) for 72 h. Saos-II cells exposed different...

Proton pump inhibitor-based triple therapy with two antibiotics for Helicobacter pylori eradication is widely accepted, but this combination fails in a considerable number of cases. Some studies have shown that cranberry inhibits the adhesion wide range microbial pathogens, including H. pylori. The aim study was to assess effect on standard lansoprazole, clarithromycin, and amoxicillin (LCA) patients peptic ulcer disease (PUD).In study, pylori-positive PUD were randomized into groups: Group...

Although the prevalence of Helicobacter pylori infection decreased following hygiene promotion and application proper anti- H.pylori treatments, unfortunately gradual increase is reported in treatment failure; hence, a regimen as second-line therapy great importance.In current randomized, clinical trial, total 120 patients with peptic ulcers who failed to respond were enrolled. In OLA group, omeprazole 40 mg/day, levofloxacin 1 g/day, amoxicillin 2 g/ day was prescribed; however, bismuth...

Bone defects are common and persistent problems in clinical orthopedics dentistry. The development of synthetic reconstruction materials is essential owing to the restricted access natural bone grafts, disease transmission risks, surgical costs, donor-site morbidity, infections, immune response-related complications. present study was done evaluate histopathological, histomorphometrical, radiological characteristics composite foams containing hydroxyapatite/bioactive glass (HA/BG)...

Iron overload in β-thalassemia major leads to oxidative damage tissues, which may have an important role the onset and progression of oral diseases.The aim this study was evaluate salivary stress indicators, total protein, iron, pH children with their relationship status dental caries comparison healthy children.In case-control study, 68 children, who were age- sex matched, selected. Two mililiters saliva collected from each child. The measured using meter paper. Thiobarbituric acid reactive...

Objectives: This study aimed to assess the effect of hyaluronic acid (HA) mucoadhesives with two different concentrations on palatal epithelial wound healing and postoperative discomfort following free gingival graft (FGG) surgery. Materials Methods: In this triple-blind, randomized, controlled clinical trial, 39 patients undergoing FGG surgery were randomly allocated three groups (N=13). Following harvesting, experimental received containing 0.8% 0.2% HA, while control group without HA. all...

The effect of head position on reproducibility volumetric measurements Cone-beam computed tomography (CBCT) scans has not been evaluated before. Thus, this study aimed to assess the changes in linear and CBCT different positions respective object.In experimental study, 16 balls were placed containers underwent neutral 8 altered positions. horizontal vertical diameters each ball measured by OnDemand software while volume was quantified ITK-Snap software. nine analyzed Cronbach's α. Paired...

Cone beam computed tomography (CBCT) and multidetector (MDCT) are frequently used in dental maxillofacial problems. This study aimed to assess the genotoxicity cytotoxicity effects of CBCT MDCT radiographies on exfoliated buccal epithelial cells during examinations.This prospective experimental was conducted at Babol University Medical Sciences (Babol, Iran) from March 2021 April 2021.
