this case report represents the outcome of endodontic treatment in an infected mandibular molar with periradicular periodontitis and inherent poor prognosis of root canal treatment due to severe root curvature. the tooth was successfully treated by leaving the mesial root non-obturated, the canal orifices were coronally sealed with calcium enriched mixture cement and a definitive coronal amalga...

BACKGROUND Postoperative coronal imbalance is a significant problem after selective thoracic fusion for primary thoracic and compensatory lumbar curves in adolescent idiopathic scoliosis (AIS). However, longitudinal studies on postoperative behavior of coronal balance are lacking. This multicenter retrospective study was conducted to analyze factors related to onset and remodeling of postoperat...

Introduction: Cervical root resorption is one of the most important complications of intra coronal bleaching. A way of preventing this type of resorption is using a coronal barrier under the bleaching materials. The aim of this study was to compare the sealing ability of glass ionomer cement and Pro Root Mineral Trioxide Aggregate (MTA) as a coronal barrier in intra coronal bleaching. Materi...

The ‘‘coronal heating problem’’ has been with us over 60 years, and hundreds of theoretical models have been proposed without an obvious solution in sight. In this paper we point out that observations show no evidence for local heating in the solar corona, but rather for heating below the corona in the transition region and upper chromosphere, with subsequent chromospheric evaporation as known ...

Based on unmarkedness of coronal cross-linguistically, coronal has been considered to be underspecified. Also, place assimilation where coronal tends to assimilate to the adjacent labial or velar by a featurefilling rule has been support the underspecification of coronals. I instead argue that coronal should be specified in Optimality Theory despite its unmarkedness, and place assimilation no l...

background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...

introduction: coronal leakage seems to play an important role in the failure of endodontic treatment. a double seal over root canal filling has been suggested as a means of improving the coronal seal. several restorative materials have been used in an attempt to produce a coronal barrier. the purpose of this study was to assess gray-coloured mineral trioxide aggregate (gmta), white-coloured min...

apert syndrome is a congenital craniosynostosis syndrome comprising of bilateral coronal synostosis , symmetric syndactyly of hands and feet and midface hypoplasia. we present an atypical phenotype of this syndrome with right sided unilateral coronal synostosis. however, type i apert hand and other clinical and radiological features suggestthe diagnosis. genetic analysis revealed an absence of ...

A simple, yet powerful, algorithm for computed tomography of the solar corona is demonstrated using synthetic EUV data. A minimum of three perspectives are required. These may be obtained from STEREO/EUVI plus an instrument near Earth, e.g. TRACE or SOHO/EIT. Subject headings: methods: data analysis — Sun: corona — techniques: image processing
