The purpose of this study was to compare the efficacy between use bovine bone graft material and platelet-rich fibrin (PRF) mixture (test group) collagen membrane combination (control in 2-stage maxillary sinus augmentation. According specific inclusion/exclusion criteria, patients treated 2008 2012 were selected. Panoramic radiographs used for radiologic assessments. To evaluate relationship sinus-graft height each implant, level (BL) divided by implant length (IL). change grafted sinus,...

The histological processing of teeth is highly complicated because containing both mineralized hard tissues and soft tissues. Depending on the type decalcification agents used in processing, mild-to-severe deterioration tissue structure inadequacies clear staining details by stain may be observed. This study aims to compare differences preparations from decalcified undecalcified tooth roots three different embedding materials techniques. Following extraction, human single-rooted crowns were...

It has been suggested diabetes plays an important role in tooth loss. Studies examining the periodontal structures and alveolar bone architecture diabetics have revealed some alterations. However, mechanisms responsible for these alterations not elucidated completely. Established relationships between cementum layer, which is resistant to resorption, are few number. The aim of this study was compare thickness layer Type 2 diabetic non-diabetic subjects order improve understanding dental...

Nitric oxide (NO) is produced by NO synthase (NOS) isoforms: neuronal NOS (nNOS), endothelial (eNOS) and inducible (iNOS). It believed that, while nNOS eNOS are effective in regulation of normal physiological processes, iNOS expressed at an increasing rate especially inflammatory process. The aim this study was to determine the presence immunoreactivity (iNOS-IR) and, compare iNOS-IR islet Langerhans cells (LC), acinar (AC), centroacinar (CC) ductal (DC) immunohistochemical (IHC) method...

It is asserted that epithelial rests in dental follicle (DF) existing around the impacted teeth adults are effective cyst formation. In this study, it intended for determining and comparing immunoreactivity (IR) ratio of ATF-2 Fra-2 proteins, members Activator Protein-1 (AP-1) family which regulates important cellular activities such as growth, proliferation differentiation, DF cells (EC) connective tissue (CC). (ATF-2-IR Fra-2-IR) EC CC tissues obtained from 30 patients were analyzed by...

Nitric oxide (NO) is a signaling molecule which can play role in pancreatic pathophysiology and involved regulation of beta cell mass. produced by the enzyme NO synthase (NOS). has three major isoforms; one them, inducible NOS (iNOS) expressed almost every type. In healthy tissues, iNOS immunoreactivity was demonstrated islet Langerhans cells, centroacinar cells ductal cells. addition, induction also acute pancreatitis, type 1 2 diabetes mellitus. When come up against inflammatory cytokines,...

The aim of this study was to evaluate the Vector system in comparison conventional technique cavity preparation. Four extracted primary teeth with no restorations and similar fissure carious lesions four permanent for orthodontic reasons were used. Class I preparations made provided that caries depth remained within dentin limits. Two treated an aerator, other two had tissue removed system. Prepared cavities evaluated scanning electron microscopy surface roughness dentine enamel removal...

Abstract – A maxillary incisor that had been replanted immediately after avulsion 49 years previously was evaluated histologically extraction. The histological evaluation revealed resorption of the apical root surface, depositions in cement with different phases and mineral density, changes periodontal ligament.

OZET Aksesuar mental foramen nadir gorulen bir anatomik va ryasyondur. Bulunma sikligi cesitli irklarda farklilik gostermekle beraber, literature gore %1.4 ile %12.5 arasinda degismektedir. 6 yasinda erkek hastanin 3D BTsinde sag foramenin anteriorunda, asil foramene daha kucuk ve sut kaninin kokunun mesiali hizasinda, alveol kretin tepesine yakin olmak uzere konumlanmis aksesuar tespit edildi. Dishekimligi kliniklerinde teshis tedavi prosedurlerinde, ozellikle implant yerlestirilmesi gibi...

Nitric oxide, produced by inducible nitric oxide synthase (iNOS), has been implicated in the pathogenesis of periapical inflammatory lesions (PILs); however, its existence pericoronal dental follicles (DFs) asymptomatic unerupted third molars is not entirely clear. The aim this study to analyze and compare presence iNOS immunoreactivity (iNOS-IR) granulomas (PGs) radicular cysts (RCs), which are two different stages PILs chronic process, DFs may transform into tissues, other pathologies. In...
