Silverfil Dental Products


Silverfil Argentum Silverfil Argentum conforms to ISO 1559: 1995, EN 1641: 2004 and ISO 24234:2004 Tested at City University, London and University of Malaya, Kuala Lumpur to confirm there is no excess mercury in the fillings. Silverfil Argentum is biocompatible (Primary Skin Irritation, Skin Sensitization, Cytotoxicity and Genotoxicity). Amalgamation (chemical reaction) of Silverfil Argentum is completed in just 30 minutes. Silverfil Argentum has a high coefficient of diffusion for mercury. Tests revealed that Silverfil Argentum is similar to a mineral in nature, 'Moschellandsbergite'. Silverfil Argentum can be work-hardened. Silverfil Argentum is totally crystalline in structure and has only one phase called the 'Noble Phase'. Silverfil Argentum has been tested, approved and successfully used for over a decade.

Tests & Studies Conducted on Silverfil Argentum

1. Conformance of Silverfil Argentum to International Standards

Silverfil Argentum has been tested and conforms to the following international standards:

ISO 1559: 1995 - Dental Material - Alloys for Dental Amalgam

EN 1641: 2004 - Dentistry - Medical Devices for Dentistry - Material

ISO 24234:2004 - Dental Mercury

2. Tests Confirming Absence of Free Mercury in Silverfil Argentum Fillings

Silverfil Argentum has been tested at the City University, London and the Institute of Advance Studies, University of Malaya, Kuala Lumpur.

City University, London on 10th September 1990.

X-ray mapping and Metallographic Examinations by J.D.R Walker revealed that there was no evidence of any excess mercury in the fillings.

Institute of Advance Studies, University Malaya on 20th October 1995.

Optical Absorption by Shimadzu UV-3000 and SEM and Electronic Dispersive X-ray (EDAX) by Phillips SEM EDAX unit revealed that there were no traces of any excess mercury in the fillings.

3. Tests on Biocompatibility of Silverfil Argentum

Allergy & Immunology Research Centre, Institute of Medical Research, Kuala Lumpur

on 15th May 2003.

Primary Skin Irritation and Skin Sensitization tests conducted as per ISO 10993-10 by Dr. Shahnaz Murad revealed that Silverfil Argentum is biocompatible.

Herbal Medicine Research Centre, Institute of Medical Research, Kuala Lumpur on

20th November 2002

Cytotoxicity tests conducted as per ISO 10993-5 by Dr. Noor Rain Abdullah concluded that Silverfil Argentum is not to have any toxic effect.

Genotoxicity tests conducted as per ISO 10993 at the University of Science, Malaysia concluded that Silverfil Argentum does not have any genotoxic effects.

4. Tests on Chemical Reaction Completion (Amalgamation process) on Silverfil Argentum

Department of Chemistry, University Malaya, Kuala Lumpur on 5th July 2003

X-ray diffraction tests by Dr. Wan Jeffrey Basirun revealed that after 30 minutes, the entire mixed mass' amalgamation was complete.

5. Tests on Coefficient of Diffusion of Silverfil Argentum

Department of Chemistry, University Malaya, Kuala Lumpur on 8th June 2003

Diffusion constant tests using the Randles-Sevcik equation resulted in a value of 7.09 x 10^-9 m² s^-1, inferring that Silverfil Argentum has a high coefficient of diffusion with mercury.

6. Study Revealing that Silverfil Argentum is similar to a mineral in nature

Department of Geology, University Malaya, Kuala Lumpur on 20th May 2004

Monochromatic X-ray diffraction tests by Assoc. Prof Dr. Azman A. Ghani revealed that Silverfil Argentum is similar to a mineral in nature called 'Moschellandsbergite', found in the district of Landsberg, Obermoschel, Rhineland-Pfalz, Germany.

7. Study on Ability to Work-Harden Silverfil Argentum Fillings

Roller-ball technique tests revealed that the Vickers hardness of the filling changed from an initial value of 53 Vickers to 106 Vickers after work hardening for 24 hours. This shows that Silverfil Argentum fillings becomes harder in the mouth over time from mastication, due to its work-hardening properties.

8. Study on microstructure of Silverfil Argentum

Silverfil Argentum has a totally crystalline structure and only one phase known as the 'Noble phase'. Silverfil Argentum has two different types of grains interlocking with each other. These two different grains are the original components of the powder.

9. Usability Testing and Approvals on Silverfil Argentum

Silverfil Argentum has undergone vigorous usability testing since 1990 at:

Private Dental Clinics in Kuala Lumpur

Government Dental Hospital Clinics in Johore, Malaysia

Armed Forces Dental Clinics in Kuala Lumpur

Children's Department of the Dental Faculty, University Malaya, Kuala Lumpur.

Silverfil Argentum has been tested and approved by the School of Stomatology, University of Peking, China.

Silverfil Argentum has received EC-Certification (CE Mark) and has also received approval from the State Food and Drug Authority (SFDA) of China.

In August 2003, the Director of the Oral Health Division of the Ministry of Health Malaysia issued a directive that all government dental hospitals and clinics shall use only Silverfil Argentum amalgams and none other due to the absence of excess mercury in Silverfil Argentum fillings.
