Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
Objective: To study and compare the effects of different demineralizationinhibition
methods on the shear bond strength (SBS) and fracture mode of an
adhesive used to bond orthodontic brackets to demineralized enamel surfaces.
Methods: Eighty freshly extracted, human maxillary premolars were divided
into 4 equal groups and demineralized over the course of 21 days. Brackets were
bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding
was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany).
Before bonding, pre-treatment with acidulated phosphate fluor ...Daha fazlası
Amaç: Bu çalışmada, süt dişlerinde; kalsiyum hidroksit (KH) ve mineral trioksit agregat (MTA) vital amputasyon uygulamalarının klinik ve radyolojik olarak değerlendirilmesi amaçlandı. Gereç ve Yöntemler: Yaşları 6-10 yıl arasında değişen 64 çocuğun, derin dentin çürüğü teşhisi konulan ve amputasyon tedavisi gereksinimi olduğu düşünülen toplam 64 alt süt azı dişi, KH ve MTA amputasyonu uygulanmak üzere rastgele iki çalışma grubuna ayrıldı. Tedavilerin tamamlanmasının ardından dişler, 3'er aylık aralıklarla 1 yıl boyunca klinik ve radyolojik olarak takip edildi. Bulgular: Klinik başarı, KH grubu ...Daha fazlası
Objective
We evaluated the detachment force, amount of deformation, fracture mode, and pull-out force of 3 different wires used for bonded lingual retainer fabrication.
Methods
We tested 0.0215-inch five-stranded wire (PentaOne, Masel; group I), 0.016 × 0.022-inch dead-soft eight-braided wire (Bond-A-Braid, Reliance; group II), and 0.0195-inch dead-soft coaxial wire (Respond, Ormco; group III). To test detachment force, deformation, and fracture mode, we embedded 94 lower incisor teeth in acrylic blocks in pairs. Retainer wires were bonded to the teeth and vertically directed force was ap ...Daha fazlası
