Various degrees of gingival overgrowth may occur in individuals taking diphenylhydantoin, a drug used widely in the treatment of epilepsy. The tissue overgrowth is made up predominantly of collagen, and may therefore be a useful model for analysis of fibrosis and some other connective tissue abnormalities. Fibroblasts derived from the overgrown tissue exhibit a level of protein synthetic activi...

BACKGROUND AND AIMS Considering the importance of disinfecting dentin after cavity preparation and the possible effect of disinfection methods on induction of various reactions between the tooth structure and the adhesive restorative material, the aim of the present study was to evaluate microleakage of composite resin restorations after disinfecting the prepared dentin surface with Nd:YAG and ...

OBJECTIVES Laser reshaping of cartilage is an emerging technology aimed at replacing conventional techniques for aesthetic and reconstructive surgery. Little is known about the mechanisms of wound healing following the photothermal heating during laser reshaping and, ultimately, how collagen remodels in the irradiated tissue. Healthy hyaline and elastic cartilage as found in the ear, nose, lary...

introduction: low-level laser therapy (lllt) is shown effective in healing diabetic foot ulcer when combined with conventional therapy. since; diabetes mellitus is a leading cause of impaired wound healing. the aim of this study is to determine the effect of different diabetic control’s methods on the healing response of diabetic foot ulcer in those patients treated with low level laser therapy...

Melanin pigmentation of the gingiva is a common occurrence. Depending on the gingival display during smiling, corrective measures may be needed for an esthetic purpose. Diode laser is a minimally invasive treatment option for the treatment of gingival melanin pigmentation. Three case reports of gingival depigmentation procedure performed using a 980 nm diode laser are presented here.

Background: The ideal result of successful periodontal therapy is regeneration. Guided tissue regeneration considered currently as gold standard for Poor mechanical properties, biomaterials instability and lack biocompatibility regenerative membrane alone led to direct use bioactive materials in defect area. So, this study was intended towards evaluation effectiveness resorbable with molecule c...

Gingival fibromatosis is a progressive enlargement of the gingiva. It may hinder oral cavity hygiene and result in underlying bone loss. The long-term benefits of surgery cannot be predicted. On the other hand, alternative, efficient and non-invasive methods are not available at present. The aim of this study was to test the inhibitory effects of a chimeric IgG variant on collagen fibril format...

BACKGROUND AND OBJECTIVE The low level laser therapy (LLLT) has been used in Dentistry to improve wound healing. In order to analyse the effect of LLLT on the in vitro proliferation of gingival fibroblasts we developed a primary culture of human gingival fibroblasts. STUDY DESIGN/MATERIALS AND METHODS The cell line named LMF was grown in Dulbecco's Modified Eagle's medium (DME) with either 5%...

This study investigated some immunological features by experimental periodontitis (EP) and rheumatoid arthritis (RA) disease interact in destructive processes in arthritic rats. Rats were assigned to the following groups: EP +RA; RA; EP; and Negative Control. RA was induced by immunizations with type-II collagen and a local immunization with Complete Freund's adjuvant in the paw. Periodontitis ...
