The invention relates to a flashlight device comprising at least one unit for generating flashlight and at least one unit for focusing the generated flashlight. The invention further relates to methods for the use thereof and to a set comprising at least one flashlight device according to the invention and a light-curable material, and to a device.

A dispensing outlet includes a housing with a first end of the housing having a first outlet and a second end of the housing having a mixing or reception space. The mixing or reception space is configured to receive a further component, and a pre-determined breaking point is formed between the first outlet and the mixing or reception space.

A syringe for injecting solid, hard and rough granular material includes: a longitudinal injection chamber having constant section and an internal diameter of less than 4.5 mm, having a distal outlet mouth for the flow out of the material, whose surface is the same as the injection chamber, and a proximal mouth, in which granular material is inserted; a plunger sealedly mobile along the injection chamber, joined to a stem which enters the injection chamber through the proximal mouth, the plunger having: a transversal section which sealingly couples with the surface of the injection chamber, and having an operative surface, facing towards the distal mouth of the injection chamber; and a body projecting longitudinally internally of the injection chamber, fixed substantially axially to the operating surface of the plunger, having a diameter that is less than 70% of that of the injection chamber and a length greater than 6 mm.

A dispensing device for a dental material, comprises a container that has a passageway with a front opening for releasing the dental material, and a rear opening. The device has a first fill opening in the passageway arranged between the rear opening and the front opening. The device further has a second fill opening. The device is adapted to receive a piston in the passageway which is movable between the rear opening and the front opening.

A compressible dental instrument to non-impressively adapt restorative material through compression comprises a handle portion (2), having a docking aperture (4) to interface with a highly compressible foam insert (10) with a docking extrusion and a tip holder (14) having highly compressible tip (16). A user can dock both to compressively adapt composite resin to a tooth's surface by first applying a restorative to a tooth and second applying the compressible portion to the restorative. Applied pressure compresses the tip to non-impressively micro manipulate composite resin.
