The effect of mouth rinses on surface micro hardness of two esthetic restorative materials
...Show More Authors

Objective: To evaluate the effect of mouth rinses (Biofresh and ZAK) on the surface micro hardness
of two light cure restorative material (Tetric ceram ivoclar-vivadent) and (3M Z 250) dental
composite.
Methodology: The microhardness values of (sixty) composite specimens were measured at the top
surfaces after 24 hours of immersion in different solutions (Biofresh, Zak mouth wash and distilled
water as control). Comparison done using descriptive statistics (mean, SD, SEM, minimum and
maximum values) and inferential statistics (ANOVA and LSD) test.
Results: The biofresh mouth rinse which has high alcohol containing has less effect on
microhardness of tetric ceram than the zak &distiled water , while the effect of Zak mouth rinse on
microhhybrid composit (3M Z250) is less than biofresh &distiled water, also there was highly
significant difference between subgroup of tetric ceram and the same for (3M Z250) composite & the
effect of the mouth rinse on hardness was material dependent it may be attributed to the differences
in chemical composition and filler type of each material. Since it was found that alcohol is not the only
factor that has the softening effect on the restorative material, other ingredient in a mouth rinse. may
have softening effect on polymer matrix.
Recommendations: We recommend for a comparison of color stability for restorative material
under the effect of mouth rinsing.

...Show More Authors

This study included isolation and characterization of extremely halophilic bacteria from Al-Massab Al-Aam region in South of Iraq Fifty isolates were identified by using numerical taxonomy 40 strains belonged to the genus Halobacterium which inclucted Hb. halobium Hb. cutirubrum Hb. salinarium Hb. saccharovorum Hb. valismortis and Hb. volcanii. Ten strains belonged to the genus Halococcus which included Hc. morrhuae Hc. saccharolyticus. Growth curves were sensitive mutants determined for wild type and salt Generation time in logarthmic phase was measured and found to be (10.37 2hr 7 0.59) for Hb. salinarium / 18 (6.490 hr 0.24) for Hb. cutirubrum / 32, (6.700 hr + 0.488) for Hb. valismortis / 20, (11.243 hr + 0.96) for Hb. volcanii / 7.
