Antibacterial and Toxic Effect of Hydrogen Peroxide Combined with Different Concentrations of Chlorhexidine in Comparison with Sodium Hypochlorite.

Statement Of The Problem: Hydrogen peroxide (H2O2) has been suggested to be used in sequence or in combination with chlorhexidine (CHX) to enhance the antibacterial activity against Enterococcus faecalis, but there is no research in the literature on the safety and effectiveness of this irrigation protocol.

Purpose: This study aimed to assess the cytocompatibility and antibacterial activity of different concentrations of CHX combined with H2O2in comparison with the activity of 5.25 and 2.

Utilization of Orthodontic Services in the Fars Province, Iran: The Reasons People Travel to the Capital for Orthodontic Treatment.

Statement Of The Problem: The first step towards appropriately planning orthodontic treatment and prevention services is to understand the needs and demands of the target population. However, this is ignored in most developing countries.

Purpose: This study aims to evaluate the attitudes of patients in Fars province towards travelling to the provincial capital (Shiraz) to receive orthodontic treatments.

Cytotoxicity of chlorhexidine-hydrogen peroxide combination in different concentrations on cultured human periodontal ligament fibroblasts.

Background: A strong antimicrobial synergism between chlorhexidine (CHX) and hydrogen peroxide (H2O2) has been reported, but there is not enough data on the cytotoxicity of this combination. The primary aim of this study was to evaluate the cytotoxicity of CHX-H2O2 combination in different concentrations and secondary aim is to assess the influence of H2O2 on cytotoxicity of CHX on cultured human periodontal ligament (PDL) fibroblasts.

Materials And Methods: The PDL cells were cultured from healthy human third molar teeth and were exposed to six prepared solutions (0.

Oral manifestations of allograft recipients before and after renal transplantation.

Renal transplantation is considered the best treatment option for patients with end-stage renal disease. In this study, the prevalence of oral lesions was studied in a cohort of renal transplant recipients before and after transplantation. Fifty-nine kidney transplant recipients were examined one week before and four months after transplantation.

Comparing two methods of education (virtual versus traditional) on learning of Iranian dental students: a post-test only design study.

Background: The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields.Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning.

Comparison of the cleaning capacity of Mtwo and Pro Taper rotary systems and manual instruments in primary teeth.

Background: Root canal cleaning is an important step in endodontic therapy. In order to develop better techniques, a new generation of endodontic instruments has been designed. The aim of this study was to compare the effectiveness of manual K-files (Mani Co, Tokyo, Japan) and two rotary systems-Mtwo (Dentsply-Maillefer, Ballaigues, Switzerland) and ProTaper (VDW, Munich, Germany)-for root canal preparation in primary molars.

Rotary Mtwo system versus manual K-file instruments: efficacy in preparing primary and permanent molar root canals.

Aim: To compare the cleaning ability and preparation time of rotary instruments (Mtwo) and conventional manual instruments (K-file) in preparing primary and permanent molar root canals.

Materials And Methods: Access cavities were prepared in 70 primary and 70 permanent teeth and India ink was injected into 120 canals of selected molars. The teeth were randomly divided into two main subgroups (n=20) and three control groups (n=10).

A Twenty-year Survey of Pathologic Reports of Two Common Types of Chronic Periapical Lesions in Shiraz Dental School.

Background And Aims: Accurate differential diagnosis between radicular cysts and periapical granulomas cannot be made from radiographs alone. Histological prevalence studies, therefore, assume special importance and may aid the clinician in making judgments regarding therapy. The incidence of radicular cysts has ranged with wide discrepancies in data.
