statement of problem: streptococcus viridans is one of the most important micro-organisms in the establishment of infections leading to dental caries and heart valve damages. therefore the diagnosis and prevention of these infections is critical in health care. purpose: the aim of this in-vivo study was to determine the prevalence of viridans streptococci in abscesses occurring in the maxillofa...

Human immunodeficiency virus (HIV) infection remains a serious problem in northern Thailand. A high prevalence of perinatally HIV-infected children with oral candidiasis has been observed in the region. The objective of this study was to determine oral colonization of Candida spp. in children with perinatal HIV infection. Samples were collected by oral rinse or oral swab from 40 HIV-infected ch...

Cystic fibrosis (CF) airways harbour complex and dynamic polymicrobial communities that include many oral bacteria. Despite increased knowledge of CF airway microbiomes the interaction between established CF pathogens and other resident microbes and resulting impact on disease progression is poorly understood. Previous studies have demonstrated that oral commensal streptococci of the Anginosus ...

PURPOSE Autologous stem cell transplantation for total limbal stem cell deficiency is immunologically preferable, to avoid allograft rejection. This study was undertaken to investigate the possibility of a novel tissue engineering approach for ocular surface reconstruction, using autologous oral mucosal epithelial stem cells expanded ex vivo on temperature-responsive cell culture surfaces. ME...

conclusions the results of the present study demonstrate that oral contraceptives containing estradiol can lead to candida colonization in the oral cavity. it is recommended that further studies comparing the influence of oral contraceptives on candida’s adherence to the epithelium is highly recommended. results the frequency of positive cultures of candida albicans was higher (p value = 0.03) ...

Inadequate access to preventive oral health services contributes to oral health disparities and is a major public health concern in the United States. Federally Qualified Health Centers play a critical role in improving access to care for populations affected by oral health disparities but face a number of administrative challenges associated with implementation of oral health integration model...

OBJECTIVES We report on a heterosexual male with sore throat diagnosed as oral Trichomoniasis vaginalis. METHODS A rapid strep test and throat culture were negative. An oropharyngeal swab tested positive for Trichomonas vaginalis using a nucleic acid amplification test (NAAT). RESULTS AND CONCLUSION A detailed sexual history and oropharyngeal swab testing enabled the diagnosis of oral Trich...

Background: The relationship between rheumatoid arthritis and poor oral hygiene has longbeen proven. Colonization of Porphyromonas gingivalis in the oral cavity can play an important role in rheumatoid arthritis. The aim of this study was to determine whether there is a relationship between rheumatoid arthritis disease and the presence of P. gingivalis. <stro...

Tissue engineering of bone and oral mucosa have been extensively studied independently. The aim of this study was to develop and investigate a novel combination of bone and oral mucosa in a single 3D in vitro composite tissue mimicking the natural structure of alveolar bone with an overlying oral mucosa. Rat osteosarcoma (ROS) cells were seeded into a hydroxyapatite/tri-calcium phosphate scaffo...
