Evaluation of alveolar bone loss following rapid maxillary expansion using cone-beam computed tomography

ASLI BAYSAL | İLKNUR VELİ | MEHMET İRFAN KARADEDE

Objective: To evaluate the changes in cortical bone thickness, alveolar bone height, and the incidence of dehiscence and fenestration in the surrounding alveolar bone of posterior teeth after rapid maxillary expansion (RME) treatment using cone-beam computed tomography (CBCT). Methods: The CBCT records of 20 subjects (9 boys, mean age: 13.97 ± 1.17 years; 11 girls, mean age: 13.53 ± 2.12 year) that underwent RME were selected from the archives. CBCT scans had been taken before (T1) and after (T2) the RME. Moreover, 10 of the subjects had 6-month retention (T3) records. We used th ...Daha fazlası

Mandibular asymmetry in unilateral and bilateral posterior crossbite patients using cone-beam computed tomography

İLKNUR VELİ

Objective: To test the hypotheses that (1) there is no difference in mandibular asymmetry between the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant difference in mandibular asymmetry among crossbite groups and control group. Materials and Methods: The cone-beam computed tomography scans of three groups were studied: (1) 15 patients (6 male, 9 female; mean age: 13.51 6 2.03 years) with unilateral posterior crossbite; (2) 15 patients (8 male, ...Daha fazlası

Effects of demineralizaton-inhibition procedures on the bond strength of brackets bonded to demineralized enamel surface

TANCAN UYSAL

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

Influence of Pre-Orthodontic Trainer treatment on the perioral and masticatory muscles in patients with Class II division 1 malocclusion

TANCAN UYSAL |

The aim of this follow-up study was to evaluate the effects of Pre-Orthodontic Trainer (POT) appliance on the anterior temporal, mental, orbicularis oris, and masseter muscles through electromyography (EMG) evaluations in subjects with Class II division 1 malocclusion and incompetent lips. Twenty patients (mean age: 9.8 ± 2.2 years) with a Class II division 1 malocclusion were treated with POT (Myofunctional Research Co., Queensland, Australia). A group of 15 subjects (mean age: 9.2 ± 0.9 years) with untreated Class II division 1 malocclusions was used as a control. EMG recordings of treatment ...Daha fazlası

Süt dişi vital pulpa amputasyonlarında MTA ve Ca(OH)2'nin etkinliğinin klinik ve radyolojik olarak değerlendirilmesi

MERVE AKÇAY

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
