The prospect of repair, regeneration, and remineralisation the tooth tissue is currently transitioning from exploratory stages to successful clinical applications with materials such as dentine substitutes that offer bioactive stimulation. Glass-ionomer or polyalkenoate cements are widely used in oral healthcare, especially due their ability adhere structure fluoride-releasing capacity. Since g...

A patient has been diagnosedwith a 2 cm long urethral stricture. Acspecific oral mucosa. This can be undertaken by histological examination cording to Hillary et al., 2014 urethral reconstruction or augmentation urethroplasty is suggested, rather than excision and primary anastomosis. In accordance Ram-Liebig et al., 2017 describe in their article a twostep procedure for urethral reconstruction...

paecilomyces sp, is a saprophytic fungus which has rarely been associated with human disease. we report the first case of invasive subcutaneous infection caused by this fungus in a 78-year-old female from damghan, iran, with diabetes and chronic renal failure. a biopsy provided an initial diagnosis of the mold in tissue. multiple positive fungal cultures which were obtained from the biopsied ti...

background: human papillomavirus (hpv) and p53 alterations are speculated to play a role in carcinogenesis. this study was carried out to find out the association of hpv and p53 with precancerous lesions of the oral cavity such as leukoplakia: the objective of this study was to find the association among human papilloma virus (hpv) 16 infections and p53 polymorphism in tobacco using the oral le...

introduction: oral lichen planus (olp) is a common mucocutanous disorder with unknown etiology. while current data suggest that oral lichen planus is a cell-mediated autoimmune disease, it might be associated to s+100, cd+4 and cd+8 cells. because of differential diagnosis of olp and oral lichenoid lesion (oll) is usually difficult this study was designed to compare any probable immunohistochem...

The purpose of this study was to determine whether in vivo images of oral mucosa obtained with a fiber optic confocal reflectance microscope could be used to differentiate normal and neoplastic tissues. We imaged 20 oral sites in eight patients undergoing surgery for squamous cell carcinoma. Normal and abnormal areas within the oral cavity were identified clinically, and real-time videos of eac...

In modern medical science, quantitative microscopy has been attracted the researchers for better understanding, visualization and evaluation of the biological samples, especially in the context of oral histopathological evaluation. The conventional light microscopy is, of course, a routine diagnostic method till date where lot of subjectivity is involved in terms of stain intensity, interand in...

Oral microbiota is among the most assorted in human body. In excess of 700 species have been distinguished mouth, and new sequencing techniques are permitting us to find significantly more species. The life structures oral cavity not same as that other body locales. has mucosal surfaces (the tongue, buccal mucosa, gingiva, palate), hard tissues teeth), exocrine organ tissue (major minor salivar...

background: trifluralin is a herbicide and used in agriculture widely. it enters plants through developing roots and stops plant cells from division and elongation (meristemic inhibitor). extensive application of trifluralin to control annual grasses and broadleaf weeds in agriculture, horticulture and horn garden, leads to environmental pollution and its entrance into the food chain could have...

Background and Aim: Oral mucosal lesions have various prevalence rates among different populations. Few studies have evaluated the frequency of oral mucosal lesions in Iranian population. This study aimed to determine the frequency of oral mucosal lesions and the related factors.                   &nb...
