Assessment of Maxillary Arch Depth and Width in a Group of Surgically Repaired Unilateral Cleft Lip and Palate Children Versus Normal Children .

Study Overview
=================
Brief Summary
-----------------
The aim of the present study is to determine the effect of surgically repaired UCLP on dental arch dimensions and the need for orthodontic intervention in comparison with other healthy children , the presence of dental anomalies and the best possible standards of care among this group of Egyptian children.

Detailed Description
-----------------
In arranging to distinguish and implement the best possible standards of care for UCLP children by the pediatric dental practitioner, evaluation of early treatment results after essential surgical repair of cleft lip and palate with respect to arch dimensions is fundamental. Although the dental arch dimensions for these children have been evaluated in previous studies , few examiners in Egypt handled this issue Due to racial contrasts in improvement of the dental arch and growth .The deficiency of data in Egypt tending to this insufficient assemble of children presents a gap that prevents the transport of fitting dental care to them. This is considered objective to fulfill this gap by spotting the most characteristics of dental arch dimensions in surgically repaired UCLP children and compares them with those of sound, coordinating, non-cleft.
