Anatomic variations in root canal morphology have become easier to detect with the rapid advancements in clinical and diagnostic aids. Also an increased awareness of unusual anatomic morphology and a better understanding of the root canal system guides the clinician in diagnosis and treatment of such variations in order to achieve a successful endodontic outcome. Mesiobuccal root of first maxil...

In this work, we present an adiabatic and nonadiabatic study for all the (1)Sigma(+) states dissociating below the ionic limits [i.e., Na (3s, 3p, 4s, 3d, 4p, 5s, 4d, 4f), K (4s, 4p, 5s, 3d, 5p, 4d, 6s, 4f) and Rb (5s, 5p, 4d, 6s, 6p, 5d, 7s, 4f) + H (1s)]. The ab initio calculations rely on pseudopotential, operatorial core valence correlation and full valence CI (configuration-interaction) ap...

E xtensive use of cervical traction in recent years has caused controversy among orthodontists concerning its effect on the craniofacial skeleton of a growing child, This has led to several cephalometric studies. It generally has been established that the normal forward growth of the maxilla can be inhibited by the judicious use of extraoral traction. 4s *, I12 13, I53 I9 Reductions in the XNA ...

BACKGROUND Current technological advances have allowed application of different study designs and techniques for investigation of dental anatomy. Some clinical studies have provided evidence that Cone Beam computed tomography (CBCT) scanning is an important resource in assessment of root canal systems notably to identify MB2 canals in maxillary molars as CBCT scans allow in vivo dental investig...

INTRODUCTION Our aim was to investigate 8 years of vertical changes of the gingival margin and tooth displacement of maxillary molars and incisors in adolescents and adults. METHODS Twenty-five adolescents and 10 adults were included in this study, with dental casts taken 2 and 10 years after orthodontic treatment. The gingival contour of the teeth was traced digitally using calibrated photog...

The clinical management of a maxillary first molar with six root canals is described in this case report having two the mesiobuccal (MB), distobuccal (DB), and palatal (P). prevalence such complex internal anatomy teeth rare variation. endodontic deviant canal morphology can be challenging to diagnose treat. For proper unusual cases, it essential have sound knowledge intricacies additional cana...

This study aimed to investigate the dental effects of a three-dimensional (3D) bimetric maxillary distalizing arch. The Wilson rapid molar distalization appliance for Class II molar correction was used in 14 patients (10 girls and four boys with a mean age of 12.18 years). The open coil springs were activated with bent Omega stops and Class II intermaxillary elastics. The mandibular anchorage w...
