Abstract: Disclosed herein is a method of applying dental cement to a concave surface of a dental restoration element. The concave surface of the dental restoration element is configured to mate with a first convex surface of a dental mounting structure such that there is a dental cement gap between the concave surface and the first convex surface. The method comprises: receiving the dental restoration element; receiving a cement applicator, wherein the cement applicator comprises a second convex surface, wherein the second convex surface is a transformation of the first convex surface such that it is shrunk by a reduction factor; applying the dental cement to the concave surface; inserting the second convex surface of the cement applicator into the concave surface of the dental restoration element; and removing the cement applicator from the dental restoration element to provide the dental restoration element with the applied dental cement.

Abstract: To provide a syringe tip that can prevent the syringe tip from unintentionally falling-off during filling and prevent viscous material from leaking out from gaps by securely attaching the syringe tip to a syringe and can provide excellent operability without obstructing a surgical field.
To provide syringe tip to be attached to a tip of a syringe containing viscous material to discharge the viscous material, comprising
a syringe engaging portion that engages with the syringe,
a cylindrical portion having a hollow portion with a virtual center line at its center and held by a user in the case of engaging the syringe tip with the syringe, and
a nozzle portion discharging the viscous material contained in the syringe,
wherein in the case that the maximum length (mm) between both end portions of the cylindrical portion on a virtual straight line orthogonal to the virtual central line is defined as first length A, the virtual straight line orthogonal to the virtual central line and including both end portions of the cylindrical portion constituting the first length A is defined as first virtual straight line, and the length (mm) between both end portions of the cylindrical portion on a second virtual straight line orthogonal to the virtual central line and orthogonal to the first virtual straight line is defined as second length B,
the first length A and the second length B satisfy the following relational expressions (1) to (3).
First length A/Second length B≥1.5 Relational expression (1):
13≥(First length A+Second length B)≥5 Relational expression (2):
5≥Second length B Relational expression (3):

Abstract: Aspects described herein pertain to restoring damaged portions of tooth or bone using plasma mediated deposition. In an embodiment, a biocompatible carrier gas is ionized to form a biocompatible atmospheric plasma stream. Restoration material, such as nano-scale powdered hydroxyapatite, is introduced into the plasma stream, which is then applied to a damaged portion of a bone or tooth. The restoration material is deposited on the damaged portion of the bone or tooth, thus restoring a shape and mechanical integrity of the bone or tooth.

Abstract: A dispenser for dispensing a liquid such as a tooth whitening gel can include a plunger and a housing having a first chamber that receives a first arm of the plunger and a second chamber that receives a second arm of the plunger. The housing can further include a first channel in fluid communication with the first chamber, a second channel in fluid communication with the second chamber, and a third channel formed at an intersection of the first and second channels. The housing can further include a static mixer than mixes a first liquid from the first chamber with a second liquid from the second chamber. The plunger may be disposed along a first axis and the third channel may be disposed along a second axis that intersects the first axis at an angle of between 10° and 170°.

Abstract: A cartridge having a plunger cylinder with an external diameter smaller than a piston cylinder internal diameter. The cartridge has a plunger cylinder adapted to fit within a breach opening of a syringe. The piston cylinder having a larger internal diameter than the external diameter of the plunger cylinder, the cartridge is capable of holding a larger volume of material in the piston cylinder than could be held in the plunger cylinder fitted within the syringe breach opening. A piston placed in the piston cylinder has a concave surface.

Abstract: A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.
