one of the fundamental parameters for endodontic success. Traditionally this has been determined using radiography, but electronic apex locators are increasingly being used. Electronic apex locators reduce the number of radiographs required and assist where radiographic methods create difficulty. The use of an electronic apex locator in combination with the radiograph is greater precision in th...

Background. Digital radiography has widespread use in endodontics. Determining a correct working length is vital for a proper endodontic therapy. The aim of this study was to compare the accuracy of conventional and digital radiographic techniques for root canal working length determination. Methods. After determining the real working lengths of 50 permanent maxillary central incisors (gold sta...

INTRODUCTION The purpose of this study was to investigate the effectiveness of basic root canal treatment (BRT) with tactile working length determination in terms of radiographic and clinical outcome parameters compared with endodontic treatment with standard radiographic working length control. METHODS This was a clinical, multicenter, controlled, open-label trial to evaluate BRT effectivene...

We compared genotyping by restriction fragment length polymorphism (RFLP) analysis of the amplified omp1 gene with serotyping by dot enzyme-linked immunosorbent assay (dot-ELISA) to determine the suitability of RFLP analysis for epidemiologic study. Fifteen prototypes of Chlamydia trachomatis and 30 clinical isolates were used in this study. To serotype with dot-ELISA, chlamydia antigen was spo...

BACKGROUND Genetic polymorphisms of drug metabolisms by cytochrome P450 (P450s) could affect drug response, attracting particular interest in the pharmacogenetics. Due to the importance of CYP2C19* 17 allele and its capability of super- fast metabolism and also lack of information about distribution of the alleles in Iranian population, this research aimed to use High Resolution Melting (HRM) m...
