Central giant cell granuloma (CGCG) is an uncommon, benign, proliferative, and nonodontogenic lesion whose etiology is not defined. Thought to represent a reparative response to intrabony haemorrhage and inflammation, CGCG was once regarded as a reactive lesion. Central giant cell granuloma usually is an asymptomatic lesion, which may become evident during routine radiographic examination or as...

PURPOSE In this study, we investigated the effect of silk scaffolds on one-wall periodontal intrabony defects. We conjugated nano-hydroxyapatite (nHA) onto a silk scaffold and then seeded periodontal ligament cells (PDLCs) or dental pulp cells (DPCs) onto the scaffold. METHODS Five dogs were used in this study. Bilateral 4 mm×2 mm (depth×mesiodistal width), one-wall intrabony periodontal defe...

background: lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. the bitemporal (visor) flap is a regional flap...

amebloblastoma as the most common epithelial odontogenic neoplasm may occur in two forms of central and peripheral. this report presents a case of a 41-year-old iranian female with a six-month complaint from a painless mass in the right posterior portion of the mandible. the case was diagnosed as an exophytic epulis-like peripheral component with characteristics of peripheral ameloblastoma and ...

congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...

fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. to increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. in 46 patients (48.8%) fixed perfusion ...

AIM This randomized clinical trial compares the usefulness of adjunctive antibiotics, while strict asepsis was followed during periodontal surgery involving guided tissue regeneration. MATERIALS AND METHODS Two groups of 20 consecutive patients each with advanced periodontal disease were randomly assigned to treatment. They displayed one angular defect each with an intrabony component ≥3 mm, ...

Aim: To analyze the clinical results of regenerative treatment intrabony defects using minimally invasive flaps in patients with periodontitis.Methods: A scoping review was conducted. Pubmed, Scopus, Ebsco Complete, and OpenGrey were searched for relevant articles several (probing depth, insertion level, gingival margin recession) radiographic indicators evaluated. We also evaluated flap design...

Periodontal therapy has proven to be effective in the control and rehabilitation of periodontal diseases.1 Although initial therapy or the debrided phase is indicated for all types of periodontal diseases, it is not the only treatment that can or should be provided for patients suffering from moderate to advanced forms of periodontitis to achieve the appropriate goal of an environment that the ...

by employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (cnt) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. the calculations are base...
