INTRODUCTION With the advent of cone-beam computed tomography (CBCT) scans, there has been a transition toward these scans' replacing traditional radiographs for orthodontic diagnosis and treatment planning. Children represent a significant proportion of orthodontic patients. Similar CBCT exposure settings are predicted to result in higher equivalent doses(More)
The purpose of this discussion was to give the practitioner a better understanding of the diagnostic processes involved in evaluating a crossbite and arriving at a differential diagnosis. It is hoped that the material presented helps to show the logical steps required to arrive at an intelligent diagnosis. The section on appliances was presented to show the(More)
OBJECTIVE In light of the increased recognition of the potential for lens opacification after low-dose radiation exposures, we investigated the effect of leaded eyeglasses worn during dental cone-beam computerized tomography (CBCT) procedures on the radiation absorbed dose to the eye and suggest simple methods to reduce risk of radiation cataract(More)
Many parameter estimation problems in chemical or biochemical engineering lead to ill-conditioned and nonconvex optimization problems. For bad starting values the use gradient based result in local optimal solutions. To overcome this drawback, a global optimization approach, Simulated Annealing, has been coupled with a gradient-based SQP approach. To(More)
Pain and discomfort are prevalent symptoms among the vast majority of patients with fixed orthodontic appliances and is the most disliked aspect of treatment. The periodontium is a highly innervated structure that also provides the necessary trophic factors, such as nerve growth factor, which promote neuronal survival, maintenance and axonal growth, via(More)
This article illustrates some of the principles and diagnostic techniques that can be used to manage patients with vertical dimension problems. It is paramount to the treatment of these patients to make a proper diagnosis of the problem areas before doing a treatment plan. This involves the use of cephalometric analysis in both the static and the dynamic(More)
BACKGROUND AND OBJECTIVES A new method for the preparation of leukocyte-poor platelet concentrates was developed, based on a short, hard spin of a pool of 5 buffy coats (BCs) combined with automated collection of the platelets. MATERIALS AND METHODS The characteristics of platelet concentrates (PCs) were studied as a function of the total g force applied(More)
