Abstract:

BACKGROUND: Oral environment is bacterial, and so the effects of restorative treatments face challenges from micro-organisms. To some extent, the success of treatment depends on the antimicrobial properties of restorative material. The silver antibacterial agent has become a research hotspot for its characteristics of broad spectrum antimicrobial, high biological security and rare drug tolerance.
OBJECTIVE: To review the application and research of inorganic silver-carrying antibacterial agent in prosthodontics material and provide a theoretical basis for the further clinical application.
METHODS: CNKI, PubMed and OVID databases were retrieved online for articles concerning the application of inorganic silver-carrying antibacterial agent in oral prosthodontics from 1990-01 to 2011-04. Articles highly related to the application and research of inorganic silver-carrying antibacterial agent in oral prosthodontics that published recently or in the authorized journals were included. Twenty-nine articles were included in result analysis.
RESUTS AND CONCLUSION: Silver is an effective antibacterial material and has a good effect on oral common pathogenic bacteria, such as candita albicans, streptococcus mutans and lactobacillus. Application of silver into prosthodontics material has a broad prospect. However, silver ion is unstable and tarnished easily. In the modification study of prosthodontics material, it is needed to further research for overcoming oxidizing discoloration, reducing the affection of silver on material physical and chemical properties, as well as the clinical application and evaluation of prosthodontics material.
