[ 1 ] - بررسی میزان القاء اینترلوکین-1 بتا (IL-1β)، فاکتور نکروزدهنده توموری (TNF-α) و مایلوپراکسیداز (MPO) پالپ دندان رت هایپرگلیسمیک توسط مینرال تری اکساید اگریگیت (MTA) و سمان غنی شده با کلسیم (CEM)
مقدمه: هدف این مطالعه بررسی میزان بیان اینترلوکین-1 بتا (IL-1β)، فاکتور نکروزدهنده توموری (TNF-α) و مایلوپراکسیداز (MPO) بعد از استفاده از MTA))Mineral Trioxide Aggregate و Calcium-Enriched Mixture (CEM) به عنوان پالپ کپ در رتهای دیابتی بود. مواد و روشها: از مدل حیوانی با القای دیابت با استفاده از Streptozotocin (تزریق داخل صفاقی به صورت mg/kg 65) استفاده شد. 34 رت به دو گروه دیابتی و سا...
[ 2 ] - Comparative evaluation of fracture and defect in reciproc and rotary files in severe curved root canals
Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...
[ 3 ] - Analgesic effects of gabapentin and ibuprofen on the pain in post therapy of root canal; a randomized double-blind clinical trial
Introduction: Inhibiting the pain which affects both the patients and dentists is an important factor during treating dental patients. The aim of this study was to assess the analgesic effect of two medications ibuprofen and gabapentin on the post-endodontic-therapy pain. Methods: Forty patients who need root canal therapy with Visual Analog Scale (VAS)>40, participated in this double-...
[ 4 ] - A comparative evaluation of apical microleakage of MTA fillapex and AH26 sealers in the presence of blood in the canal space of the teeth
Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...
[ 5 ] - Histopathologic Responses of the Dental Pulp to Calcium-Enriched Mixture (CEM) and Mineral Trioxide Aggregate (MTA) in Diabetic and Non-Diabetic Rats
Diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. The aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using MTA or CEM cement in diabetic rats. Thirty two Wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...
[ 6 ] - Mother’s Knowledge Regarding Oral Health among Their Preschool Children
Background The maintenance and health of children's milk teeth are important due to the high rate of caries and the fact that their health clearly affects the permanent teeth, the treatment of these caries and its complications leads to high costs for families and the society. This study aimed to determine the mother’s knowledge and att...
[ 7 ] - Coronavirus as a New Challenge for Infection Control in Dentistry: A Literature Review
Modes of transmission of the COVID-19 virus are still unclear. The virus could spread through direct routes, including aerosols and saliva, and indirect transmission through contaminated surfaces. Dental practitioners produce airborne infectious particles especially when using rotary instruments during treatment. Oral fluids, blood, and oral mucosa are also sources of infection, so dentists ar...
[ 8 ] - An Ex vivo Analysis of Apical Transportation in Root Canals Prepared with BT Race Rotary and Hand K-Flexofile by Cone Beam Computed Tomography
Background and purpose: The purpose of mechanical cleaning of the root canal is to clean the canal walls, create a conical shape to facilitate access, effective washing, and filling all areas of the root canal. Errors such as root canal transportation are cuased by excessive dentin removal from the canal. The objective of this study was to investigate root canal transportation by a BT Race rota...
[ 9 ] - Radiographic Evaluation of Periapical Radiolucencies
Background and purpose: Periapical inflammatory lesions are localized periapical bone reactions that result from pulp necrosis and inflammation or periodontal diseases. Inappropriate treatments are often considered as one of the main factors associated with apical periodontitis. This study was done to evaluate periapical radiolucencies in panoramic radiographs. Materials and methods: In this c...
[ 10 ] - Ex Vivo Comparison of File Fracture and File Deformation in Canals with Moderate Curvature: Neolix Rotary System versus Manual K-files
Background and Aim: Cleaning and shaping is one of the important steps in endodontic treatment, which has an important role in root canal treatment outcome. This study evaluated the rate of file fracture and file deformation in Neolix rotary system and K-files in shaping of the mesiobuccal canal of maxillary first molars with moderate curvature. Materials and Methods: In this ex vivo exp...
[ 11 ] - Evaluation of Root Canal Transportation using Bio Race and K -Flexo file instruments: using cone-Bean Computed
Background & Aim: Deviation from the original shape of the canal leads to poor filling and lack of proper canal seal and consequently to the failure of root treatment The aim of this experimental study was to determine the extent of apical transportation after instrumentation with hand K-Flexofile and BioRace rotary instruments by cone-beam computed tomography (CBCT). Material and Methods: In t...
