BACKGROUND Several lengthening techniques have been proposed for upper eyelid retraction in patients with Graves' orbitopathy and variable rates of success have been reported. Most authors recommend different procedures for different degrees of retraction, but cannot prevent residual temporal retraction in a significant number of cases. The modified levator aponeurosis recession described by Ha...

OBJECTIVES Tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. The purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration. MATERIALS AND METHODS Tissue samples were obtained from crown-lengthening procedures and wisdom teeth...

Obtaining predictable and aesthetic root coverage has become an important part of periodontal therapy. Several techniques have been developed to achieve these goals with variable out comes. The aim of this case series was to evaluate the effectiveness of Acellular Dermal Matrix Allograft (ADMA) and Subepithelial Connective Tissue Graft (SCTG) in combination with Coronally Positioned Flap (CPF) ...

BACKGROUND Achieving of moisture control especially gingival bleeding control is great challenge in clinical practice. Various hemostatic agents and techniques have been promoted for bleeding control during dental operation. But few studies have focused on the cytotoxicity of hemostatic solutions. AIM The aim of this study was to evaluate cytotoxic effect of hemostatic agents on human gingiva...

PURPOSE To investigate systematically the early morphologic changes in axon terminals of adult mammalian rod and cone photoreceptors prepared as a sheet for subretinal transplantation. METHODS An in vitro system was designed to maintain adult porcine retinas for up to 48 hours. Photoreceptor sheets, prepared by vibratome sectioning, and full-thickness retinas were cultured at temperatures sim...

OBJECTIVES The purpose of this in vitro study was to evaluate the microleakage in "deep" Class II composite restorations with gingival cavosurface margin below the CEJ (cemento-enamel junction) and restored with different techniques. STUDY DESIGN Fifty human teeth were used. In each tooth two standardized Class II slot cavities (on mesial and on distal surfaces) were prepared: the buccolingua...

in this work, different types of chaotic 1-manifolds which lie on the chaotic spheres or on a torus are introduced. some types of retractions of the chaotic spheres affect on the 1-chaotic systems, and other types of retractions occur to the geometric manifold but make the 1-chaotic manifold invariant. the existed retractions are discussed through new proved theorems. also we construct diffe...

The purpose of this study was to qualitatively compare three recent techniques of Langerhans cells detection in oral epithelium and to quantitatively compare Langerhans cells in clinically normal and clinically inflamed human gingival biopsies. Eleven subjects were selected who displayed chronic periodontitis and moderate gingival inflammation. A quadrant associated with clinically inflamed tis...

A pleasing smile involves a harmonious relationship among the teeth, the gingival scaffold and the lip framework. In dental profession, aesthetics of the patient is the main factor to be focused on along with treating the disease of the patient. The primary goal of esthetic dental treatment is the restoration to a natural, healthy, and esthetic appearance from an otherwise damaged dentition [1]...

AIM To review evidence for the treatments of gingival recession and root caries in older populations. MATERIALS & METHODS A systematic approach was adopted to identify reviews and articles to allow us to evaluate the treatments for gingival recession and root caries. Searches were performed in PubMed, Medline and Embase, the Cochrane trials register and bibliographies of European and World Wo...
