introduction: cigarette smoking is a risk factor for progression of periodontitis, which effects on the incidence, extent and severity of the periodontal disease and no other known factors can be harmful as much as smoking to the periodontal tissues. the purpose of this study was to determine clinical and histopathological effects of smoking on free gingiva in smokers and non-smokers with chron...

Various lineages of amniotes display keratinized skin appendages (feathers, hairs, and scales) that differentiate in the embryo from genetically controlled developmental units whose spatial organization is patterned by reaction-diffusion mechanisms (RDMs). We show that, contrary to skin appendages in other amniotes (as well as body scales in crocodiles), face and jaws scales of crocodiles are r...

This case report demonstrated a modified technique of free gingival graft (FGG) aiming to increase keratinized attached tissue in large recipient areas. A FGG to increase the amount of attached gingival tissue, facilitate oral hygiene, and prevent further clinical attachment loss was realized in two patients. Because the extensive recipient area, a modified technique was performed to obtain a s...

Lip and cheek adhesion due to trauma, burns or tumors causes inadequate vestibular depth. Shallow vestibule appears clinically as mucogingival stress that may be a reason of esthetic and functional problems, such as recession. In this case, 70 years old female patient represent with complaint of restricted upper lip movement. Clinic examination and patient history revealed that, patient has sca...

The aim of this study was to compare the differential gene expression and stemness in the human gingiva and dental follicles (DFs) according to their biological characteristics. Gingiva (n = 9) and DFs (n = 9) were collected from 18 children. Comparative gene expression profiles were collected using cDNA microarray. The expression of development, chemotaxis, mesenchymal stem cells (MSCs), and i...

The American Academy of Periodontology 1 has defined marginal tissue recession as an acquired deformity with the gingival margin being located apical to the cementoenamel junction (CEJ), resulting in exposed root surface and loss of attached gingiva. Gingival recession is a common feature in populations with high as well as poor standards of oral hygiene 2 . Many factors have been proposed to i...

objectives: gingival recession can lead to root exposure and discomfort for patients. there are various techniques for root coverage. the aim of this study was to compare the use of gingival unit graft (palatal graft including the marginal gingiva and papillae) with free gingival graft for treatment of localized gingival recession. materials and methods: in this randomized controlled clinical t...

BACKGROUND AND PURPOSE CT and MR imaging are useful for evaluating the extension of carcinomas in the face and neck. We evaluated the involvement by carcinoma arising from the gingiva (ie, gingival cancer) by using CT and MR imaging. METHODS We retrospectively examined 122 patients with squamous cell carcinoma (SCCA) in the lower (88 patients) and upper (34 patients) gingiva. Extension of SCC...
