The attachment behavior of the human periodontal ligament (PDL) fibroblasts to root-end filling materials (amalgam and Super-EBA) was compared in vitro to gutta-percha by means of scanning electron microscope. STUDY DESIGN: Amalgam and Super-EBA...
The purpose of this study was to evaluate the antibacterial effectiveness of Octenisept (OCT; Sch€ulke & Mayr GmBH, Norderstedt, Germany), 1% alexidine (ALX) (Santa Cruz Biotechnology, Inc, Santa Cruz, CA), and 2% chlorhexidine (CHX) against...
The purpose of this study was to evaluate the antibacterial activity of ethanol and hexane extracts of Salvadora persica against common oral pathogens.
Materials and methods: Well diffusion, Minimum Inhibition Concentration (MIC), Minimum...
Tooth agenesis in human being is the most common congenital anomaly associated with dental development. Mutations in many genes such as MSH homeobox 1 (MSX1), paired box gene 9 (PAX9), ectodysplasin A (EDA) and EDA receptor (EDAR) have been...
Aim The purpose of this study was to determine the effect of different cavity disinfectants on microleakage of Class V resin-based composite restorations in primary teeth.
Materials and methods Standard non-beveled Class V cavities were prepared on...
Aim: The aim of this investigation was to compare the efficacy of passive ultrasonic irrigation (PUI) with either 2.5% sodium hypochlorite (NaOCl) or saline, with that of conventional syringe irrigation on intraradicular Enterococcus faecalis...
The efficacy of Salvadora persica extracts in preserving the viability of human foreskin fibroblasts
Abstract Objective: To evaluate the efficacy of Salvadora persica hexane and ethanol extracts in preserving the viability of human foreskin fibroblasts.
Materials and methods: Normal human foreskin cells were cultivated in Dulbecco modified Minimum...
Purpose: To evaluate the quality of the apical 5-mm seal produced by different filling techniques using a bacterial leakage model.Materials and Methods: Sixty-five extracted single-rooted human teeth were deco- ronated, prepared, and instrumented....
Purpose: The oral cavity is a rich ecosystem with a plethora of microorganisms, and different components of !xed or- thodontic appliances may contribute to a shift in the balance of oral ecology. The purpose of this study was to investi- gate the...
Aim: To evaluate thcacy of ethanolic extract of Salvadora persica (S. persica) and BioPure MTAD (a mixture of a tetracycline isomer, an acid, and a detergent) in removing the intracanal smear layer of primary teeth.
Materials and methods: The root...
Objectives: To evaluate the combined effect of a mixture of tetracycline, acid, and detergent (MTAD) and Nisin againstEnterococcus faecalis (E. faecalis) and Actinomyces viscosus (A. viscosus) biofilms.
Methods: This study was conducted between...
Objectives: To assess the cytotoxic potential of Salvadora persica (S. persica) extracts on human gingival fibroblast (HGF) cells.
Methods: !is study was conducted between January and May 2012 in collaboration with Dental Caries Research Chair,...
Aims: The aim of the study was to evaluate the ability of a mixture of (castor detergent and papain enzyme) MCP to remove the smear layer by using scanning electron microscope. Materials and Methods: Samples of 45 human extracted was divided in...
Inflammatory lesions in the periapical tissues of the teeth are a result of root canal infection following partial or complete breakdown of the pulp. Infected root canals have a complex microbial flora consisting of cocci, rods, spirochaetes,...
Abstract: This study compared the difference in decision making regarding retreatment of endodontically treated teeth by general dental practitioners and endodontists. Thirty radiographs of endodontically treated teeth taken from undergraduate...
To evaluate the efficacy of an ethanolic Salvadora persica extract in removing the smear layer following a root canal procedure. Methods: Sixty extracted, single-rooted human teeth were cleaned, shaped, and divided into four groups. Experimental...
The attachment and morphologyof human periodontal ligament fibroblasts to mineral trioxide aggregate (MTA) was evaluated using a scanning electron microscope. The material was placed at an apical cavity of 30 single-rooted slices of extracted human...
Aim To evaluate the technical quality of root fillings performed in the undergraduate clinic of the Dental College, King Saud University, Saudi Arabia and to compare the technical quality of root canal treatment between the 4th- and 5th-year...
Sodium hypochlorite is one of the most commonly used antimicrobial irrigating solution in endodontic therapy. It should ideally be confined to the root canal system but incidences of injection into the periradicular area have been reported. Such an...
Root end preparation was performed in the apical third of 20 endodontically treated extracted human teeth using high speed, low speed, straight surgical low speed handpieces and ultrasonic machine. The surface properties of the cut root surface...
The purpose of this study was to evaluate in vitro the effect of different variables (delivery system, surface contact with the irrigant, the frequency of changing the irrigant and the total volume of the irrigant) of sodium hypochlorite on the...
This in vitro study evaluated the microbial leakage of Cavit, IRM, and Dyract when used as temporary filling materials after root canal treatment. The degree of coronal leakage was assessed by using a microbiological marker consisting of...
The purpose of this laboratory exercise was to describe the fabrication of an in vitro model, containing natural teeth, for teaching the principles of conventional endodontic procedures to preclinical dental students. Maxillary and mandibular models...
The aim of this study was to evaluate the integrity of the coronal seal of Temp-Bond and compare it to
Cavit and IRM after post space preparation using S. faecalis as a microbial tracer. In addition, the affect
of two methods of gutta percha removal...
