Oral cancer knowledge among dental patients in Isfahan.

Background: Diagnosis of oral cancer in the early stages is the most effective tool to improve survival and reduce complications caused by the disease. The aim of this study was investigating the dental patients' knowledge of oral cancer in Isfahan.

Materials And Methods: This descriptive cross-sectional study was performed on 334 patients referred to dental centers in Isfahan, Shahinshahr, Najafabad, Khomeini Shahr, Harand, and Zarrinshahr cities.

Cyclin D1 and Ki-67 expression and its correlation with histopathological parameters and cervical lymph node metastasis in oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma (OSCC) is the most common malignant tumor among oral cancers. Cyclin D1 and Ki-67 have associated with cell division. The aim of this study was to compare the expression of these markers in OSCC with and without cervical lymph node (LN) metastasis.

Histological characteristics of dental pulp in teeth with periodontal problems and healthy teeth.

Background: Chronic periodontitis is the most common type of periodontitis, which is associated with calculus and plaque accumulation. Several studies have indicated that uncured periodontitis can affect the dental pulp. However, this relationship is controversial.

Evaluation of changes in Salivary Lactate Dehydrogenase Level for detection of Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis Study.

Background: Research has examined the relationship between salivary lactate dehydrogenase (LDH) levels and head and neck squamous cell carcinoma (HNSCC) screening and prognosis. Due to biochemical changes in cancer cells and increased production of lactate products in the body. The present systematic review aims to evaluate the changes in salivary LDH levels in HNSCC patients.

Evaluation of Dentists' Attitudes Towards Principles of Professional Ethics.

Objective: The aim of this research was to investigate attitudes towards principles of professional ethics (PPE) amongst Iranian dentists working in Isfahan, Iran.

Methods: This pilot cross-sectional study was conducted amongst 273 dentists in Isfahan, Iran. A validated, comprehensive questionnaire including principles of respect for patient autonomy, nonmaleficence, beneficence, and justice was used to evaluate dentistry professional ethics aspects.

Evaluation of Epstein-Barr virus expression in oral squamous cell carcinomas.

Background: Oral squamous cell carcinoma (OSCC) is one of the most common cancers. Epstein-Barr virus (EBV) has been related to throat-esophageal and gastric cancers. The aim of this study was to evaluate the prevalence of EBV in OSCC.

Efficacy of exenatide, ozone, and methyl prednisolone for the recovery of infraorbital nerve paresthesia after injury in rats.

Background: Infraorbital nerve injury often occurs due to zygomatic complex fracture. There is no standard protocol to restore the sensory and motor function of the nerve after injury. Some medications are used to improve nerve function.

Synthesis of full interpenetrating hemicellulose hydrogel networks.

Two methods with different cross-linking mechanisms for designing hemicellulose-based full interpenetrating polymer networks (IPNs) were developed through the sequential synthesis of full IPNs from O-acetyl-galactoglucomannan (AcGGM) utilizing free-radical polymerization and a thiol-ene click reaction. A faster swelling rate was observed for all IPN formulations compared with the single-network gels. The highly porous structure of the IPNs with small interconnected pores was verified using scanning electron microscopy.

Thiolated hemicellulose as a versatile platform for one-pot click-type hydrogel synthesis.

A one-pot synthetic methodology for the thiolation of O-acetyl-galactoglucomannan (AcGGM) was developed to merge hemicellulose chemistry with "click" chemistry. This was realized by the AcGGM-mediated nucleophilic ring-opening of γ-thiobutyrolactone via the activation of the polysaccharide pendant hydroxyl groups. The incorporation of thiol functionalities onto the hemicellulose backbone was visualized by (1)H and (13)C NMR spectroscopy and was assessed by an Ellman's reagent assay of the thiol groups.

Unrefined wood hydrolysates are viable reactants for the reproducible synthesis of highly swellable hydrogels.

A value-adding robust and sequential synthetic pathway was elaborated to produce hydrogel structures with ionic character from crude acetylated galactoglucomannan-rich wood hydrolysate (WH). The WH was first-step liquor originating from a sulphite cracking pulp process for dissolving pulp. The synthetically modified WH fractions were verified at each step by NMR and FTIR, and the hydrogels were characterized with respect to their swelling and mechanical properties.

Mast cells distribution and variations in epithelium thickness and basement membrane in oral lichen planus lesion and oral lichenoid reaction.

Background: Oral lichen planus (OLP) is a chronic mucocutaneous lesion with unknown etiology. Oral lichenoid lesions (OLL) comprise a family of lesions with different etiologies. Both lesions have similar clinical and histopathologic characteristics although their management is different.
