Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
81 words
A dental tape having length, width, edges and two sides for removing plaque from the teeth comprising a strong, flexible, tear-resistant tape having a multitude of rows of protuberances fixed in place which are aligned obliquely to the length of the tape, having preselected spacing between said rows and between said protuberances, and which lift debris in a preferred direction away from the base of the teeth towards the ends of the teeth, the debris riding along the rows aligned obliquely.
Claim 2
Dependent Claim
81 words
A dental tape having length, width, edges and two sides for removing plaque from the teeth comprising a strong, flexible, tear-resistant tape having a multitude of rows of protuberances fixed in place which are aligned obliquely to the length of the tape, having preselected spacing between said rows and between said protuberances, and which lift debris in a preferred direction away from the base of the teeth towards the ends of the teeth, the debris riding along the rows aligned obliquely.
Claim 3
Dependent Claim
28 words
