Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...

External apical root resorption following orthodontic treatment.

The Angle orthodontist, 2000
This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR.

Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim was to examine whether a Ca(OH)2 paste affects fracture strength of teeth. Sixty extracted maxillary central incisors were prepared to simulate immature teeth. Another 40 were used as mature teeth. The ten groups (n = 10) were: (1) immature control; (2) immature + access; (3) immature + access + 1 m Ca(OH)2; (4) immature + access + 12 ...

Comparison of diagnostic efficacy of conventional radiography, digital radiography and Cone Beam Computed Tomography (CBCT) in apical root resorptions

مجله دانشگاه علوم پزشکی بیرجند, 2018
Background and Aim: Since the external root resorption is not detectable clinically, therefore radiographic examination is very important for diagnose, Therefore, the purpose of this study is to compare the diagnostic efficiency of conventional, digital ...

Cerebral Ventriculomegaly With Abnormality of the Aqueduct of Sylvius: A Case Series

Clinical Genetics, EarlyView.
Genetic testing leads to a diagnostic rate of ~30% in a fetal cohort with cerebral ventriculomegaly where the neuropathological examination revealed a stenosis or atresia of the aqueduct of Sylvius. ABSTRACT Fetal cerebral ventriculomegalies are brain anomalies with potentially poor neurodevelopmental prognosis.
