Microleakage of fluoride containing propolis varnish

الملخص EN

Dental cavity varnishes used to coat the freshly cut tooth structure to reduce micro leakage and post-operative hyper-sensitivity.

Dental cavity varnishes are prepared from natural gum or synthetic resin dissolved in a volatile organic sol-vent.

The aim of this study is preparation of the fluoridated cavity varnish from pro-polis.

Propolis is a natural gum used by bees to seal their honeycombs ; it is avail-able, cheap material in Iraq.

The effectiveness of the propolis varnish in reducing the micro leakage under amalgam restoration was evaluated by micro leakage test by which micro leakage tested by penetration of methylene blue dye and examined microscopically.

The data was analyzed statistically with ANOVA and Duncan’s Multiple Range Test.

The results of this study showed that the fluoridated propolis varnish has a good quality and it is highly effective in reducing the micro leakage under amalgam restoration.
