Title
(EN) DENTAL RESINS
(FR) RESINES DENTAIRES
Abstract
(EN) Dental resins and dental compositions utilizing such resins are described. The dental compositions are particularly useful as cavity liners and root canal sealants which contain calcium hydroxide (or calcium oxide) and which are utilized to deliver calcium to exposed dental pulp. The resins, and resin-containing compounds, include eutectic mixtures of polyfunctional salicylates. In particular, the transesterification of a blend of trimethylolpropane and neopentylglycol with methyl salicylate yields a blend of trimethylolpropanetrisalicylate and neopentylglycoldisalicylate, which is contemplated by the present invention.
(FR) L'invention concerne des résines dentaires et des compositions dentaires utilisant de telles résines. Les compositions dentaires sont particulièrement utiles en tant que vernis pour protection pulpo-dentaire et pâtes de scellement des canaux radiculaires renfermant de l'hydroxyde de calcium (ou de l'oxyde de calcium) et utilisés pour apporter du calcium à la pulpe dentaire dénudée. Les résines et les composés renfermant de la résine comprennent des mélanges eutectiques de salicylates polyfonctionnels. En particulier, la transestérification d'un mélange de triméthylolpropane et de néopentylglycol avec du salicylate de méthyle produit un mélange de triméthylolpropanetrisalicylate et de néopentylglycoldisalicylate, faisant l'objet de la présente invention.
