Abstract: The invention relates to a testing kit to test dental unit waterlines to meet the CDC water safety monitoring guideline using EPA compliant standards. The CDC recommends water used in non-surgical procedures to be delivered from dental unit waterlines that follow the Environmental Protection Agency's (EPA) standard for safe drinking, which contain less than or equal to 500 colony forming units of heterotrophic bacteria per milliliter of water (?500 CFU/mL). The goal of the invention is the development of a cost effective in-office test kit to monitor the safety of dental unit waterlines by following suggested EPA protocol of counting bacteria colonies after bacteria has gone through an incubation period.

Abstract: The invention relates to a bracket for fixing to the exterior face of a tooth, the bracket having a base, which lies against the tooth and in which a trapezoid shape slot is configured to receive a wire bow. The base of the slot runs essentially perpendicularly in the oral cavity with elevated surface, thus retaining the wire bow, which exerts forces and torques in an essentially horizontal direction, in an optimum position in the slot. The unique form of the inventive brackets has a dimple concave female surface and a channel for attachments to passes through which would allow the female to receive a convex male surface extension from the attachments and form a locking mechanism between concave female surface and the attachment convex male extension when attachment is used during the Orthodontic treatment. This unique model of locking mechanism has created a new inventive platform in Orthodontics for interchangeable attachments.

Abstract: An improved implant root for tooth implanting into the alveolar bone of a patient, said implant root comprises: a coarse threaded portion of the implant root is formed to have a wider base and to have an extension root with various radiant thread constructed, characterized with a circumferential constricted neck between these two segments. Both segments are designed to be seated into alveolar bone as implant root fixture. The widest diameter of the upper and lower segment is either equal or the lower base is slightly wider than lower segment for the most of it. The constricted neck in between the base and extension of the segments and the shape of the lower base segment allow the lower base implant root to serve as a primary stability anchor.
