OBJECTIVE To compare measurements from human skulls and their images from cephalometric radiographs (CR) and computed tomography (CT) scanograms, in order to gauge the potential clinical use of the latter. DESIGN Based on specific inclusion criteria, including stable centric occlusion, 13 adult skulls were selected from a larger collection. The mandible(More)
The exchange of fluids and chemicals between the tooth pulp and the periphery, through the dentinal tubules has been well documented. Application of irritants on the open tubules produces aversion in awake rats that can be prevented by prior occlusion of these tubules. This study aims at characterizing the secretion of inflammatory mediators in tooth(More)
PURPOSE The objective of this study was to compare two methods for reducing gagging induced by stimulation of the soft palate: table salt and nitrous oxide inhalation sedation. MATERIALS AND METHODS Fifteen healthy volunteers, eight men and seven women with a mean age of 20.6 years, were subjected to a gagging event three times using a large tablespoon to(More)
UNLABELLED Oromandibular dystonia is a rare condition of hyperkinetic motor dysfunction in the orofacial area. It is a centrally mediated disorder of unknown aetiology and manifested by a sustained contraction of masticatory muscles, involving one or both lateral pterygoids, and pushing the mandible forward. The prognosis is poor and the treatment is(More)
The purpose of this article is to review impression materials used for fabricating fixed restorations in dentistry. Their compositions, properties, advantages, and disadvantages are presented and compared. How these properties influence clinical decisions is also described. This review helps the clinician choose which material is more suitable for a(More)
PURPOSE The aim of this article is to review the current literature with regard to prosthetic considerations and their influence on the outcome of immediately loaded implants. MATERIALS AND METHODS A broad search of the published literature was performed using MEDLINE and PubMed to identify pertinent articles. RESULTS One hundred fifty six references(More)
INTRODUCTION Several morphological and functional features contribute to the consideration of the tooth as a separate compartment having special type of innervation and special immune mechanisms. This study describes a new method allowing the intradental perfusion of rat incisors for the in vivo assessment of pulpal reaction to inflammatory agents. (More)
Increasingly popular, implant-retained mandibular overdentures have a highly predictable success rate and provide many options in terms of design and attachment systems. General dentists may have some difficulties in choosing the appropriate system. This paper provides a general overview of the various options that are available, taking into consideration(More)
