Anti-dentin autoantibodies are associated with inflammatory root resorption in permanent teeth and are modulated by dental trauma and orthodontic force. However, it is not known whether deciduous tooth trauma can stimulate the development of a humoral immune response against dentin. The aim of this study was to evaluate the levels of salivary SIgA reactivity against human dentin extract in youn...

The purpose of this paper is to assess the added risk pose by radio frequency (RF) induced heating near fixed orthodontic appliances in patients undergoing MRI examination at 3 Tesla. Three of the most commonly used types of fixed orthodontic appliances: Palatal expander (Hyrax) Lingual Bar and Multibracket-/-band braces were investigated using a head phantom and positioned to match the in-vivo...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...

The aim of this study was to evaluate the allergenic potential of orthodontic brackets, comparing the cutaneous sensitivity provoked by metals present in conventional metallic brackets to that provoked by brackets with a low concentration of nickel, known as "nickel-free". A sample was selected from 400 patients undergoing treatment in the orthodontic clinic of the Pontifical Catholic Universit...

S umm ary An epoxy resin formulation has been developed to bond orthodontic attachments to enamel sur­ faces. The disruptive force required to break the bond under experimental conditions was in excess of the forces exerted on the orthodontic attach­ ments during treatment. This formulation has been subjected to a limited number of clinical trials. These tend to substantiate the experimental fi...

[Purpose] The aim of this study was to investigate the effect of an exercise intervention on the balance ability and muscle function of elderly women. [Subjects] The subjects were randomly divided into a control group (n=10) and an exercise group (n=10). [Methods] The subjects participated in an elastic band exercise program lasting for 8 weeks, exercising for 40 minutes, four days a week with ...

Tessier cleft no. 30 is a rare congenital anomaly. It may range in severity from median cleft of the upper and lower lip to cleft of the manubrium sterni involving the mandible, floor of the mouth, tongue, hyoid bone, thyroid cartilage and strap muscles. Ankyloglossia and median web in the neck extending from chin resulting in neck contracture are frequently found. This is a case report of medi...

one common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. the recent effort to improve the resistance against the demineralization ...
