Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 7551 was prepared by Technical Committee
lSO/TC 106, Dentistry, Subcommittee SC 1, Filling and restorative
materials.

Introduction
The sizes of the absorbent points specified in this International Standard
have been aligned with the corresponding sizes for obturating points
specified in IS0 6877.
Specific qualitative and quantitative requirements for freedom from
biological hazard are not included in this International Standard, but it is
recommended that in assessing possible or toxicological hazards,

reference should be made to IS0
Dental absorbent points are used in root-canal therapy to dry root canals or
to carry medicaments into the root canal. They are therefore made of fine-
grade absorbent material with a close texture to give an essentially
smooth lint-free surface. To enable insertion into a prepared root canal, the
absorbent point must have some rigidity, be essentially straight and
circular in cross-section.

INTERNATIONAL STANDARD @ IS0
Dental absorbent points
1 Scope
This International Standard specifies requirements and test methods for nonmedicated absorbent points used in
endodontic procedures.
The requirements apply to absorbent points which have been sterilized once in a manner approved by the
manufacturer. Dental absorbent points include standard points and taper size points.
This International Standard does not specify requirements or test methods for sterility and/or freedom from
biological hazard of dental absorbent points.
