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
Amaç: Nekrotik pulpalı immatür dişlerde kök ucunun açık olması, kök kanal sisteminin geniş ve kök ucuna doğru genişleyerek sonlanması nedeniyle bu dişlerde endodontik tedavi ile etkili bir apikal tıkama oluşturulması oldukça zordur. Bu yüzden bu dişlerin endodontik tedavilerinde kullanılacak kök kanal dolgu sisteminin apikal tıkama özelliği önem kazanmaktadır. Çalışmamızda hazırlanan simule immatür dişlerde yeni üretilmiş MTA Fillapex kanal dolgu patının Güta-perka ile birlikte kullanımı ve oluşturduğu apikal tıkamanın etkinliği Güta-perka/AH Plus kanal dolgu sistemi ile karşılaştırılarak in v ...Daha fazlası
Objective: To evaluate lower incisor position and bony support between
patients with Class II average- and high-angle malocclusions and compare
with the patients presenting Class I malocclusions. Methods: CBCT records of
79 patients were divided into 2 groups according to sagittal jaw relationships:
Class I and II. Each group was further divided into average- and high-angle
subgroups. Six angular and 6 linear measurements were performed. Independent
samples t-test, Kruskal–Wallis, and Dunn post-hoc tests were performed for
statistical comparisons. Results: Labial alveolar bone th ...Daha fazlası
Objectives: The aim of this study was to evaluate differences in craniofacial morphology,
head posture and hyoid bone position between mouth breathing (MB) and nasal breathing
(NB) patients.
Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of
12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were
included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements
(15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements
were evalu ...Daha fazlası
