introduction: providing desirable smile is one of the main concerns in cosmetic dentistry. hyperpigmentation is one of the esthetic concerns especially in gummy smile patients. lasers with different wavelength are used for oral surgery including carbon dioxide laser (co2), neodymium-doped yttrium aluminium garnet (nd:yag), erbium family and diode laser. in this case, all esthetic procedures inc...

Three-dimensional cell culture systems provide a convenient in vitro model for the study of complex cell-cell and cell-matrix interactions in the absence of exogenous substrates. The current study aimed to evaluate the osteogenic differentiation potential of gingiva-derived stem cells cultured in two-dimensional or three-dimensional systems. To the best of our knowledge, the present study is th...

The somatotopic organization of the human primary somatosensory (SI) area in the cerebral cortex has been intensively studied for the hand, lip, and tongue, but little is known about the gingiva. Penfield concluded that the gingival SI area was above the tongue area, as shown in his famous homunculus map. However, our recent study suggested that the lingual gingiva area was not so different to ...

Bio-engineered skin and soft tissue substitutes may be either acellular or cellular. Acellular products (eg, dermis with cellular material removed) contain a matrix or scaffold composed of materials such as collagen, hyaluronic acid, and fibronectin. The various acellular dermal matrix products can differ in a number of ways, including as species source (human, bovine, porcine), tissue source (...

OBJECTIVE To compare the postoperative healing profiles of graft materials used for endoscopic repair of cerebrospinal fluid (CSF) leak. DESIGN Retrospective cohort study with 1 to 21 months of follow-up. SETTING Tertiary referral, academic medical center. PATIENTS Consecutive sample of patients undergoing endoscopic repair of CSF leak from March 2007 through May 2009. INTERVENTION Endo...

Periodontal disease is one of the most prevalent chronic inflammatory diseases. There is a genetic component to susceptibility and resistance to this disease. Using a mouse model, we investigated the progression of alveolar bone loss by gene expression profiling of susceptible and resistant mouse strains (BALB/cByJ and A/J, respectively). We employed a novel and sensitive quantitative real-time...

BACKGROUND AND AIMS The anatomical features of gingiva are important in appropriate periodontal treatment planning. This study was designed to determine the anatomic features of gingival in a group of dental students in Tabriz, Iran. MATERIALS AND METHODS One-hundred healthy subjects (aged 20-24 years old) with no history of periodontal or orthodontic treatment and a gingival index of zero or...

the last decade has ushered in a rapidly expanding global discussion regarding acellular dermal matrix (adm) applications, economic analyses, technical considerations, benefits, and risks, with recent emphasis on adm use in breast surgery. this study aims to evaluate global trends in adm research using bibliometric analysis. the top nine plastic surgery journals were determined by impact factor...

Innervation of the molar gland and blood vessels in the lower lip, gingiva and cheek mucous membrane was investigated in the cat with the aid of whole mount acetylthiocholinesterase (WATChE) histochemistry and retrograde neuronal tracing methods with horseradish peroxidase (HRP) and HRP-conjugated wheat germ agglutinin (WGA-HRP). The molar gland was found to be supplied from the buccal nerve an...
