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...
When hard tissue augmentation is scheduled as a part of an oral rehabilitation, prior to the treatment, it is important to assess if the quality of the underlying gingiva at the recipient site can support the bone grafting procedure. The most frequent complication during autologous onlay grafts are wound dehiscences in the recipient site, so the integrity of soft tissues is a basic aspect of su...
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...
There is a great deal of controversy in the literature about the importance of keratinized gingiva around dental implants and the amount, if any, required for implant health. Some studies conclude that peri-implant health could be maintained even in the absence of keratinized gingiva providing adequate oral hygiene is employed [1]. Other studies suggest that areas of minimal keratinized gingiva...
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...
Background: Recent studies indicate an increased incidence of pertussis disease in recent years. The aim of this study was to evaluate the efficacy of the acellular vaccine for children (as a replacement of current whole cell vaccine in the Expanded Program on Immunization) and for high-risk adults in Iran through updating current best available evidence. Methods: We performed a systematic lite...
The initiation or progression of periodontitis might involve a local renin-angiotensin system (RAS) in periodontal tissue. The aim of this study was to further characterize the local RAS in human and rat periodontal tissues between healthy and periodontally-affected tissue. Components of the RAS were investigated using in vitro, ex vivo and in vivo experiments involving both human and Wistar ra...
BACKGROUND AND AIM: The present study was performed in order to assess the effect of gingival thickness on amount of gingival augmentation with and without preserving periosteum.METHODS: The study was conducted on 8 ecotype dogs aged 1-5 years. At the beginning, clinical probing depth and keratinized and attached gingiva width were measured. Totally, 64 sites were operated in this study. Perios...
