Abstract

Abstract A method for identifying and locating dental microorganisms and a device for use in the method, wherein a strip of flexible material, having a back site identifying surface and a front velvet-like surface, is placed in contact with a selected site in the oral cavity, to retain microorganisms on the velvet-like surface, and then the microorganism-containing surface is used to transfer the microorganisms onto suitable substrates that will make possible their identification.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 222 words
A dental flora-replica device particularly for use in occlusal teeth surfaces, which device is used for identifying and locating the sites of cariogenic or other microorganisms on the occlusal surfaces of teeth, which device comprises: (a) a flexible, thin strip of sheet material having a front and a back surface; (b) the front surface comprising first and second, separate, spaced-apart, elongated, generally parallel strips of sterile, velvet-like surfaces composed of a material to retain microorganisms, when the occlusal surfaces of opposing teeth are pressed against each of the velvet-like surfaces; (c) hinge means so that the first and second surfaces may be placed in an opposing relationship and in contact with occlusal teeth of a patient; (d) the back surface marked to locate the site of the designated occlusal teeth whose microorganisms are to be identified and located; and (e) a removable masking-tape means secured over the first and second velvet-like surfaces, to protect the sterile first and second surfaces prior to use, whereby in use the occlusal, dental replica device may be folded, with the first and second velvet-like surfaces extending outwardly from the top and bottom to contact the occlusal teeth, and, thereafter, the device placed in an open, flat position for application to a bacteriological identification means to identify the microorganisms retained on the first and second velvet-like surfaces.
Claim 2
Dependent Claim 222 words
A dental flora-replica device particularly for use in occlusal teeth surfaces, which device is used for identifying and locating the sites of cariogenic or other microorganisms on the occlusal surfaces of teeth, which device comprises: (a) a flexible, thin strip of sheet material having a front and a back surface; (b) the front surface comprising first and second, separate, spaced-apart, elongated, generally parallel strips of sterile, velvet-like surfaces composed of a material to retain microorganisms, when the occlusal surfaces of opposing teeth are pressed against each of the velvet-like surfaces; (c) hinge means so that the first and second surfaces may be placed in an opposing relationship and in contact with occlusal teeth of a patient; (d) the back surface marked to locate the site of the designated occlusal teeth whose microorganisms are to be identified and located; and (e) a removable masking-tape means secured over the first and second velvet-like surfaces, to protect the sterile first and second surfaces prior to use, whereby in use the occlusal, dental replica device may be folded, with the first and second velvet-like surfaces extending outwardly from the top and bottom to contact the occlusal teeth, and, thereafter, the device placed in an open, flat position for application to a bacteriological identification means to identify the microorganisms retained on the first and second velvet-like surfaces.
Claim 3
Dependent Claim 27 words
The device of claim 1 which includes a handle means secured at one end of the device, to permit introduction of the device into the oral cavity.
