It is also positive in neuroepithelial cells, precursor neural cells (NPC), and human dental pulp cells. The aim of this study was to evaluate the potential morphodifferentiation and histodifferentiation to NPC of SSEA-4 positive stem cells from human exfoliated deciduous teeth (SHED).

Antimicrobial Effect of Calcium Hydroxide Combined with Electrolyzed Superoxidized Solution at Neutral pH on Growth.

Objective: To evaluate the effect of the combination of calcium hydroxide (Ca(OH)) and a novel electrolyzed superoxidized solution at neutral pH, known as OxOral® on growth in root canals.

Methods: Sixty human teeth were used, from which root canals were infected and randomly divided into the following treatment groups: saline solution, saline solution plus Ca(OH), OxOral®, and OxOral® plus Ca(OH).

Results: A permanent reduction in bacterial growth was observed at days 1, 6, 12, and 18 after OxOral® plus Ca(OH) treatment from 4.

Electrochemical Behavior of Ti6Al4V Alloy Used in Dental Implants Immersed in and Solutions.

The titanium alloy, Ti6Al4V, is used in dentistry for dental implants because of its excellent resistance to corrosion and its high biocompatibility. However, periimplantitis is considered the main reason for treatment failure. The Ti6Al4V alloy was used to study the corrosion behavior for dental implant applications, using an experimental arrangement of three electrodes with the bacteria and , in addition to Ringer's lactate as electrolytes, at 37 °C and a pH of 5.

Chlamydia trachomatis in the gingival sulcus and pharynx in patients of Northeast Mexico.

Background: The oral microenvironment provides the conditions for the establishment of microorganisms not usually considered residents of the normal oral microbiota. Sexually transmitted microorganisms such as Chlamydia trachomatis can adhere to any mucosal surface and ascend to reach appropriate locations to survive and develop symptomatic infections.

Materials And Methods: To determine the presence of C.

Antimicrobial and Anti-Biofilm Effect of an Electrolyzed Superoxidized Solution at Neutral-pH against .

The presence of in the oral cavity has been associated to the failure of antimicrobial therapy in patients with gastrointestinal infection and the development of oral diseases. However, it has been reported that the maintenance of good oral hygiene can improve the therapeutic success rates, where the use of mouthwashes with anti- activity would help to achieve it. The aim was to evaluate the antimicrobial activity of OxOral® mouthwash against and its effect on biofilm formation.

Molecular detection of based on the presence of and virulence genes in dental plaque from patients with periodontitis.

Background/purpose: () infection is the most common in the world and is associated with various gastrointestinal pathologies, including chronic gastritis, peptic ulcers, and gastric cancer. The prevalence is associated with socioeconomic conditions, with this infection being more common in developing countries than in developed countries. The presence and permanence of in the oral cavity has been reported, but its role is controversial.

Immunoinformatics Approach to Design a Novel Epitope-Based Oral Vaccine Against .

is an infectious agent that colonizes the gastric mucosa of half of the population worldwide. This bacterium has been recognized as belonging to group 1 carcinogen by the World Health Organization for the role in development of gastritis, peptic ulcers, and cancer. Due to the increase in resistance to antibiotics used in the anti- therapy, the development of an effective vaccine is an alternative of great interest, which remains a challenge.

Immunization with a Synthetic Peptide Induces Secretory IgA Antibodies and Protects Mice against Infection.

is a spiral Gram-negative bacterium associated with inflammation of the gastric mucosa, peptic ulcer, and gastric adenocarcinoma, whose treatment has failed due to antibiotic resistance and side effects. Furthermore, because there are no vaccines effective against , an appropriate vaccine design targeting conserved/essential genes must be identified. In the present study, a 50-52 kDa immunogen-derived peptide antigen with the sequence Met-Val-Thr-Leu-Ile-Asn-Asn-Glu (MVTLINNE) was used to immunize against infection.
