The objective of this study is to prepare and study chemical compounds for cleaning denture from locally available materials. The chemical compounds solutions were (sodium bicarbonate with alum), (sodium bicarbonate with citric acid), (sodium bicarbonate with apple vinegar), (sodium bicarbonate with clear commercial vinegar), (sodium bicarbonate with thyme oil), (saturated salt solution), (clear commercial vinegar), (alum). The main study, the effects of the chemical compounds solutions were evaluated on the (color, water Sorption and transverse strength) of heat cured denture base material. The t-test showed that the highest increase in optical density for the specimens immersed in (alum), (sodium bicarbonate +alum), (sodium bicarbonate + apple vinegar) solutions at 1/2 hr immersion and it increased more at 8 hrs immersion. The conclusions of this study showed that the safest prepared solutions on the denture base material that could be used as denture cleansers are (sodium bicarbonate{7g}with clear commercial vinegar{5ml}), (sodium bicarbonate {2g} with thyme oil {3.57g}), (saturated salt solution {40g}) at 1/2 hr and 8 hrs of immersion. While, (sodium bicarbonate {2g} with citric acid {4.57g}) solution appeared its safety at 1/2 hr immersion only.

1. Epidermal explants of axolotl gastrulae were cultivated for not less than 10 days in plain salt solution and that containing a water-soluble derivative of a carcinogenetic hydrocarbon, Na-1:2:5:6-dibenzanthracene-α-β-endo-succinate. 2. None of the explants in the control series showed neurulation, while over 60% of those in the experimental series showed definite and extensive neural differentiation. 3. The induced neural structures were in the form of more or less radially symmetrical neural balls, with no regional differentiations. 4. By avoiding the use of a solid implant and thus eliminating any possible mechanical role of an inductor, it proves clearly that, as far as evocation is concerned, the chemical action alone of the evocator constitutes an adequate stimulation.
