Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO 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.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

Committee CEN/TC 55, Dentistry, in accordance with the Agreement on technical cooperation between

ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 10873:2010), which has been technically

revised. The main changes compared to the previous edition are as follows:
— the powder/water ratio described in 7.5.3.1 and 7.6.3.1 has been revised;
— the method for pH value measurement has been modified in part;
— the surface roughness of the sample holder has been revised.

7.2.3 Procedure
7.2.3.1 Type 1 adhesives
7.2.3.1.1 Class 1

Take (1,0 ± 0,1) g of a Class 1 denture adhesive in the container (7.2.1.2.1), add 5 g of propylene glycol

(7.2.2.1) to disperse it, and while stirring, add 300 ml of water (7.2.2.2) and mix them sufficiently. Insert

the electrode of the pH meter (7.2.1.1.1) into the dispersion and take the pH meter reading 3 min after

the insertion.
7.2.3.1.2 Class 2
7.2.3.1.2.1 Procedure using pH meter with a flat type compound electrode

Take (1,0 ± 0,1) g of a Class 2 denture adhesive in the container (7.2.1.2.2) and spread evenly, then pour

5,0 ml of 0,9 g/dl sodium chloride (7.2.2.3) solution onto the sample. Cover the container (7.2.1.2.2),

then keep it for 10 min. Insert the flat type pH compound electrode of the pH meter (7.2.1.1.2) into the

0,9 g/dl sodium chloride (7.2.2.3) solution and monitor the pH until a steady pH is determined.

NOTE This procedure is suitable for Class 2 denture adhesives which do not have internal diffusion capacity

against aqueous solutions.

7.2.3.1.2.2 Alternative procedure using pH meter with a glass and reference electrode

Take (1,0 ± 0,1) g of a Class 2 denture adhesive in the container (7.2.1.2.1), add 5 g of propylene glycol

(7.2.2.1) to disperse it, and while stirring, add 300 ml of water (7.2.2.2) and mix them sufficiently. Insert

the electrode of the pH meter (7.2.1.1.1) into the dispersion and take the pH meter reading 3 min after

the insertion.
NOTE This procedure is suitable for various type of Class 2 denture adhesives.
7.2.3.1.3 Class 3

Take (1,0 ± 0,1) g of a Class 3 denture adhesive in the container (7.2.1.2.1), add 300 ml of water and mix

them sufficiently. Insert the electrode of the pH meter and take the pH meter reading 3 min after the

insertion.
7.2.3.2 Type 2 adhesives

Take (1,0 ± 0,1) g of denture adhesive, and spread evenly over a radius of approximately 40 mm on a

piece of filter paper (7.2.1.3). Place the filter paper in the container (7.2.1.2.1) and add 300 ml of water

to it. After immersing in water for 1 h, insert the electrode of the pH meter into water and take the pH

meter reading 3 min after the insertion.
7.3 Determination of stability — Aging procedure

Store the denture adhesives in their original containers at (40 ± 2) °C at (75 ± 5) % relative humidity for

3 months or at such conditions of time and temperature as will simulate storage at room temperature

[16]
for 30 months .

surface roughness of 2,0 μm and below, made of poly(methyl methacrylate) complying with ISO 7823-2.

See Figure 2 a).

After testing, detergent solution is recommended to remove the denture adhesive left on the sample

holder surface.

7.5.2.3 Sample holder II, having a raised circular part with a diameter of (22 ± 1) mm, a height of

(5,0 ± 0,1) mm and a surface roughness of 2,0 μm and below, made of poly(methyl methacrylate)

complying with ISO 7823-2. See Figure 2 b).

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO 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.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,

as well as information about ISO's adherence to the World Trade Organization (WTO) principles in the

Technical Barriers to Trade (TBT) see the following URL: www .iso .org/iso/foreword .html.

The committee responsible for this document is Technical Committee ISO/TC 106, Dentistry,

Subcommittee SC 7, Oral care products.

This second edition cancels and replaces the first edition (ISO 10873:2010), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— a powder/water ratio described in 7.5.4.1 and 7.6.4.1 has been revised.
— method of pH value measurement has been modified in part.
— surface roughness of the sample holder has been revised.

Introduction

Denture adhesives are used for the improvement in retention stability of removable denture to soft

supporting tissues temporarily. This document is intended to determine the physical and chemical

properties of denture adhesives.

Specific qualitative and quantitative requirements for freedom from biological hazards are not included

in this document. It is recommended that, in assessing possible biological hazards, reference be made to

ISO 7405 and ISO 10993-1

4 Classification

For the purposes of this International Standard, denture adhesives are categorized as one of the

following types:
a) Type 1: glue type:
— Class 1: powder form;
— Class 2: cream form;
— Class 3: sheet or tape form.
b) Type 2: liner type.
5 Requirements

Particular attention should be given to assessing the effects on biocompatibility from the release of

metallic ions from the denture adhesive.
5.1.2 pH value

Denture adhesives shall have a pH value within the range of 4 to 10 when tested in accordance with 7.2

 or another validated method.

Testing for microbiological contamination shall be carried out according to appropriate methods such

as those listed in Bibliography [1] to [12].
5.1.4 Stability

The denture adhesive shall show no signs of deterioration which may affect compliance with this

International Standard after being subjected to one of the aging procedures specified in 7.3.
