BACKGROUND This randomized controlled clinical trial was designed to compare the clinical outcomes of guided tissue regeneration with calcium sulfate graft and membrane (CS) versus guided tissue regeneration with collagen membrane (CM) or open flap debridement (OFD) only in terms of clinical attachment gain in periodontal intrabony defects. METHODS(More)
BACKGROUND The use of locally delivered antibacterials containing chlorhexidine (CHX) was proposed to improve the effectiveness of non-surgical periodontal treatment. The present multicenter randomized study investigated the effects of a xanthan-based chlorhexidine (Xan-CHX) gel used as an adjunct to scaling and root planing (SRP) in the treatment of(More)
OBJECTIVES Measuring peak insertion torque in relation to different bone densities, the present study seeks to determine whether micromotion at the interface is related to primary stability achieved by increasing insertion torque. MATERIAL AND METHODS A total of 120 Ti-Bone implants were placed in fresh bovine bone samples representing three density(More)
The aim of this study is to evaluate the effectiveness of the low-level laser therapy (LLLT) in the control of pain, swelling, and trismus associated with surgical removal of impacted lower third molars. Thirty patients were randomized into two treatment groups, each with 15 patients-group test (LLLT) and a group control (no-LLLT)-and were told to avoid any(More)
Biphosphonates are largely used for their unquestionable properties of inhibiting bone resorption by osteoclasts in the treatment of various osteometabolic illnesses such as osteoporosis, multiple myeloma, tumors which metastasize to the bone and malignant hypercalcemia. In this literature review the physico-chemical properties, biologic activities and the(More)
OBJECTIVES Protocols of immediate loading have been reported in several studies. It has also been demonstrated that the cause of failure of immediate loaded implants is due to the micromotion on the bone-implant interface induced by immediate loading. There should be a minimum gap between the implant and the peri-implant bone, without micromotions occurring(More)
Zirconium oxide, known as zirconia, is a ceramic material with optimal esthetical and mechanical properties. Zirconia stabilized with yttrium oxide has the best properties for medical uses. A stress on ZrO2 surface creates a crystalline modification that opposes to propagation of cracks. Zirconia core for fixed partial dentures (FPD) on anterior and(More)
Thalassemia is an inherited blood disorder due to an imbalanced globin chain synthesis leading to anaemia that requires regular blood transfusions and iron-chelating therapy. Of all organ failures secondary to iron deposit, and all the complications, heart failure still represents the first cause of death. Osteopenia and osteoporosis can be considered(More)
Only rarely is a mature complex odontoma seen in a periapical location and in association with a primary tooth. Complex odontomas usually present as a radiopacity with a radiolucent rim. The differential diagnosis must include mature fibro-osseous lesions (e.g. cementoblastoma). Complex odontomas can be differentiated from fibro-osseous lesions because they(More)
OBJECTIVES To measure in vivo impact of dense bone overheating on implant osseointegration and peri-implant bone resorption comparing different bur irrigation methods vs. no irrigation. MATERIALS AND METHODS Twenty TI-bone implants were inserted in the inferior edge of mandibles of sheep. Different cooling procedures were used in each group: no irrigation(More)
