  • Irrigating and lavage compositions
    Patent number: 6190642
    Abstract: Irrigants to be used with vibratory scaling apparatus and lavage are provided. The irrigants of the invention are characterized in that they contain medicaments for the treatment of conditions in the mouth and have a viscosity and deliquescence adapted to substantially optimize the efficiency of the apparatus. The irrigants are formulated so that they have minimal stickiness on drying, minimal foaming and do not gum-up the apparatus in which they are used. Also provided is a method for treating dental diseases comprising applying the irrigants of the invention through a vibratory scaring apparatus to substantially optimize the efficiency of said apparatus and to substantially optimize destruction and removal of infectious bacteria using said apparatus and the removal or inactivation of endotoxins derived from bacteria or the host.
    Type: Grant

  • Methods for posterior dental restoration employing light curable packable compositions
    Patent number: 4514174
    Abstract: Novel processes for the restoration of teeth particularly posterior teeth, wherein the use of a matrix band is required, are provided employing one component, packable, actinic light curable, resin-based restorative compositions. Such methods are now capable, for the time, of employing resin-based restoratives in the posterior restoration of teeth wherein the packability of the restorative composition enable the deformation of a matrix to allow substantial restoration of the original conformation of the tooth. Packable one component actinic light curable resin-based restorative compositions are provided.
