One of the goals of the management of the developing occlusion and the correction of malocclusion is the establishment of symmetry within the individual arches (arch form) and the occlusal relationships between the maxillary and mandibular arches. The symmetry in arch form is related to the axial inclinations and rotations of the individual teeth. The occlusion is affected not only by the positions of the teeth, but also by the patterns of skeletal growth. Although these two components are interrelated, this discussion attempts to address them independently.

Introduction: In contemporary clinical settings, three-dimensional (3D) models have become an integral component of daily practice. Photogrammetry, a novel method in clinical practice, enables the creation of precise 3D models from small objects while maintaining their original shape and size.
Aim: To evaluate the accuracy and reliability of digital models (DM) generated using photogrammetry techniques compared to traditional gypsum models (GM) and to investigate the feasibility of utilizing free software for processing and manipulating digital dental models.

Tetralogy of Fallot (TOF) is a condition that often leads to long-term enlargement of the aortic root in after surgery. The aortic dilation is believed to be caused by histological abnormalities of the aortic media and the hemodynamic characteristics of increased aortic flow, compared to pulmonary flow. Severe cyanosis, severe right ventricular outflow tract (RVOT) obstruction, older age at repair, a larger aortic size at the time of repair, and a history of an aortopulmonary shunt parameters related to long-standing volume overload of the aortic root were the reported risk factors.

Purpose: This meta-analysis sought to compare knot tying against other methods of haemostasis in terms of post-operative haemorrhage, intraoperative blood loss and tonsillectomy time.
Methods: Two independent reviewers performed a literature search according to PRISMA guidelines. Three databases were consulted, Pubmed, Google Scholar and Embase.

Paediatric renal tumours include a broad range of neoplasms which largely differ, but also overlap to a smaller extent, with adult kidney cancer. These include the embryonal tumour nephroblastoma, which accounts for the majority of cases of kidney cancer in the first decade of life and, despite boasting a cure in ~ 90% cases, still presents clinical challenges in a small proportion of cases. A variety of less common mesenchymal tumours, including the mostly indolent congenital mesoblastic nephroma, clear cell sarcoma of kidney which continues to be associated with poor outcomes for higher stage disease, and the typically lethal malignant rhabdoid tumour, form the bulk of the remaining presentations in the first decade.
