Rapid palatal expansion was used to correct constricted maxillas on 29 subjects, 10 o[ whom had cle~t palates. Arch width, measured transversely at the primary canine and at the primary second molar, increased in all cases with a mean value o[ 4.0 mm. Arch perimeter (arch length) also increased approximately 4.0 mm. Correlations between change in transverse palatal dimension versus change in ar...

Background Good decision-making requires gathering and using sufficient information. Several knowledge translation platforms have been introduced in Burkina Faso to support evidence-informed decision-making. One of these is the rapid response service for health. This platform aims to provide quick access for policy-makers in Burkina Faso to highquality research evidence about health systems. Th...

We consider the use of eigenfunctions of polyharmonic operators, equipped with homogeneous Neumann boundary conditions, to approximate nonperiodic functions in compact intervals. Such expansions feature a number of advantages in comparison with classical Fourier series, including uniform convergence and more rapid decay of expansion coefficients. Having derived an asymptotic formula for expansi...

BACKGROUND Oral breathing and maxillary deficiency are often associated with steep mandibular plane angle, and retrognathic mandible compared with the faces of healthy controls. Some studies suggested that after rapid maxillary expansion, improvement in nasal breathing and repositioning of mandible with transitory increasing of facial height and, in some cases, spontaneous forward repositioning...

Maxillary transverse discrepancy usually requires expansion of the palate by a combination of orthopedic and orthodontic tooth movements. Three expansion treatment modalities are used today: rapid maxillary expansion, slow maxillary expansion and surgically assisted maxillary expansion.This article aims to review the maxillary expansion by all the three modalities and a brief on commonly used a...
