On the odderon intercept in perturbative QCD [PDF]

open access: yesZ.Phys. C75 (1997) 709-716, 1996
Arguments are presented for the odderon intercept being exactly equal to unity. A variational method is presented based on a complete system of one-gluon functions. For the odderon, the highest intercept calculated by this method is $1-(3\alpha_{s}/\pi)\,0.45$.

Dentists’ requirements for continuing professional development in Ireland. A pilot study conducted at University College Cork [PDF]

open access: yes, 2015
Aims: To determine the self-assessed continuing professional development (CPD) needs of dental practitioners and identify how each discipline can best be served by a dental CPD programme.

Reliability of Digital Dental Cast Measures as Compared to Cone-Beam Computed Tomography for Analyzing the Transverse Dimension [PDF]

open access: yes, 2017
The purpose of this study was to assess the consistency in diagnosing the transverse dimension on cone-beam computed tomography (CBCT) images as compared to digital dental models.

Orthodontic and restorative treatment in cleft lip without bone graft – case report/ Tratamento ortodôntico e restaurador em paciente com fissura labial sem enxerto ósseo – relato de [PDF]

open access: yes, 2019
Introduction: Cleft lips and palates are among the most common congenital orofacial anomalies of the head and neck. Treatment of orofacial clefts is challenging, prolonged and delivered by multidisciplinary teams.

Cone-beam CT for Dental Radiography [PDF]

open access: yesarXiv, 2018
The cone beam computed tomography (CBCT) technique was first inserted in dental imaging 15 years ago. Due to this technique 3D imaging in dentistry has been excessively changed. The purpose beyond using CBCT instead of computed tomography (CT) imaging is that CT can not be used in many cases in dentistry, in addition to the higher radiation and cost of

Orthodontic Emergencies and Perspectives During and After the COVID-19 Pandemic: The Italian Experience [PDF]

open access: yes, 2021
Objective: To investigate the types of dental emergencies that occurred during the lockdown period in Italy (12th March—4th May) and to investigate future therapeutic preferences related to the use of different types of appliances.

Aligner-induced tooth movements in three dimensions using clinical data of two patients [PDF]

open access: yesarXiv
The effectiveness of a series of optically transparent aligners for orthodontic treatments depends on the anchoring of each tooth. In contrast with roots, the crowns' positions and orientations are measurable with intraoral scans, thus avoiding any X-ray dose.

Transformer-Based Tooth Alignment Prediction With Occlusion And Collision Constraints [PDF]

open access: yesarXiv
The planning of digital orthodontic treatment requires providing tooth alignment, which not only consumes a lot of time and labor to determine manually but also relays clinical experiences heavily. In this work, we proposed a lightweight tooth alignment neural network based on Swin-transformer.
