AIM Prospectively analyze the long term structural and functional changes in patients of primary open angle glaucoma (POAG) receiving medical therapy (beta blockers and non beta blockers). In this study an attempt has been made to evaluate whether medical reduction of IOP prevents or delays the progression of glaucomatous visual field loss and/or optic nerve damage in patients with open angle g...

Aim: Present study evaluated the cytotoxicity of dentin desentisizing agents on bovine pulp-derived cells (bDPCs). 
 Materials and Methods: Transfected bDPCs were exposed to original, ½ ¼ dilutions Shield Force Plus, Gluma Teethmate Desensitizer for 24 h. Culture medium was used as a control group. The viability tested by MTT after hours exposure. Data analyzed using one-way analysis varia...

OBJECTIVE The amount and consistency of the applied forces to the tooth are important factors in tooth movements; therefore, the aim of this study was to compare the initial force and the force loss of three brands of elastics in 24 hours. MATERIALS AND METHODS In this in-vitro study sixty non-latex elastics (3/16 medium) from three companies (Forestadent, Dentaurum and Ortho Technology) were...

BACKGROUND It has been demonstrated that fluoride prophylactic agents may cause hydrogen absorption in NiTi wires and degrade their mechanical properties. AIMS To investigate the effect of a fluoride mouthwash on load-deflection characteristics of three types of nickel-titanium-based orthodontic archwires. METHODS Twenty maxillary 0.016 inch round specimens from each of the single-strand Ni...

Background. This study was designed to compare the viability of autogenous bone grafts, harvested using different methods, in order to determine the best harvesting technique with respect to more viable cells. Methods. In this animal experimental study, three harvesting methods, including manual instrument (chisel), rotary device and piezosurgery, were used for harvesting bone grafts from the l...

Background: Diabetes mellitus is the most common metabolic disorder with many complications such as neuropathic pain which relief from it is a dilemma. Objectives: To investigate the effect of hydroethanolic extract of Rubus fruticosus on neuropathic pain in diabetic rats. Materials and Methods: In this experimental case –control study, forty eight male Wistar rats (250±20 g) were ...

INTRODUCTION Solubility of root filling materials is heavily influenced by the environment they are in contact with. This study compared the solubility of ProRoot MTA in deionized water and synthetic tissue fluid. MATERIALS AND METHODS Forty specimens of prepared MTA were immersed in deionized water and synthetic tissue fluid (20 samples each). The solubility was assessed after 7 and 28 days....

abstract background: obesity is an independent risk factor of preeclampsia with unknown mechanism and hyperlipidemia might be a probable case of it. objective: the objective of this study was to determine the role of hyper-triglyceridemi in association with high prepregnancy body mass index and the risk of preeclampsia. materials and methods: the authors conducted this case-control study of 42 ...

BACKGROUND Reduced respiratory muscle endurance (RME) contributes to increased dyspnea upon exertion in patients with cardiovascular disease. OBJECTIVE The objective was to characterize ventilatory and metabolic responses during RME tests in post-myocardial infarction patients without respiratory muscle weakness. METHOD Twenty-nine subjects were allocated into three groups: recent myocardia...

This study investigated the effect of fiber reinforced composite resin (FRC) post lengths, ferrule, and full coverage metal crown on fracture resistance of endodontically treated teeth (ETT) using an experimental FRC post with the similar elastic modulus of dentin (11.5 GPa). ETT was restored according to 1 of 7 combinations of FRC post length (10, 5, 2.5, 0 mm), ferrule (0, 2 mm), and with/wit...
