Remineralizaion of teeth with tissue salts

Post by ilzepi »

Goodday,
I am a Grade 9 student at Tsumeb Gymnasium in Namibia. Currently I am busy with a study to try and remineralize teeth after i have demineralized it with different drinks (Cola, Apple juice, Energade etc.)
I have finished the first phase of this study. I have tried to remineralize the teeth with common household chemicals - Distilled water (control), Sodium bicarbonate, Magnesium sulphate, Calsium hydroxide and Sodium Fluoride (Zymafluor).
I think it will be interesting to include a Phosphate element to see if it will improve remineralization of the teeth. I am thinking about doing a study to see if the different tissue salts can remineralize the teeth.
Can you please assist me with some questions:
I would like to know if I can dissolve the tissue salts in water? I will have to crush the tissue salt tablets and dissolve it in distilled water. Then keep the teeth in this mixture for a specified time to see I can remineralize it.
Will the tissue salts disassociate in distilled water? I will need to explain the results chemically. Before hand I will need investigate the different chemical reactions, as I will need to explain chemically what happened to the different teeth.
Do you know if a similiar study was done before?
Any help or recommendations will be appreciated.
Thank you
Ané

Remineralizaion of teeth

Post by ilzepi »

Goodday,
I have finished my project (over 2 years):
Phase 1: Demineralize teeth with different drinks - Cola, Diet Cola, Apple juice, Sparkling water, Energade, Milk, Water (control).
Phase 2: Remineralize the teeth again with common chemicals - Sodiumbicarbonate, Calciumhydroxide, Magnesiumsulphate, Sodiumfluoride and Distilled water (control).
I would like to do another phase on this project. Could you please assist me?
I can either combine the different chemicals to see if a greater results will be achieved when remineralising teeth? I am afraid the chemistry will get complicated with this option...
I have also thought about adding minerals to for example apple juice and see if I can reduce the demneralizing effect of the apple juice. But I think the minerals can alter the taste of the apple juice?
Please help me?

Hello!

This sounds like a very interesting project! Have you thought about diluting some of your different drinks, such that they are less intense, and seeing how this impacts the rate/degree of demineralization? While this would not affect the taste (other than making it less concentrated) and would not impact the chemistry significantly, seeing how the concentration of these particular drinks impacts mineralization is a pretty low hanging fruit and has very interesting implications! It also provides a middle ground between your control (water) and your results. I'll admit, cola with water sounds pretty gross.

Best of luck. Cool project!

Greetings!

Many factors contribute to the solubility of a compound in water. One of the main factors is the compounds bond strength. Take for example the tissue salt Calcarea Fluorica (Calc Fluor). Its' basic chemical formula is CaF2. Fluoride is very electronegative, and thus the bonding forces between Ca2+ and each fluoride anions are very strong, they are tightly held together in the crystal form. A few water molecules do not have enough strength to get in between and dissolve it. However, compounds like CaCl2, CaBr2 have weaker bonds, and thus will readily dissolve in water.

Restoring enamel is a major subject of interest in the science community. Below is a link to PubMed about a study on the recent advancements in tissue re-mineralization. Best of luck!

Greetings,

Expanding on the most recent post. Have you looked into adding baking soda? This is a very common/easy method to lower the acidity of apple juice. However, depending on the amount it can slightly alter the taste, but why kind of apple juice you are using may be more flavorful and thus the baking soda may not have a huge effect. Another idea would be to look into alkalizing drops, or pH drops. These drops are commonly used to make water more alkaline. They may retain the taste of the apple juice, while also raising the pH.

Cheers!

Hello Ilzepi, Dr Stein and Jacqueline K,

Since these posts are on the same topic, I've merged them so each of you will see all of the responses.

Best of luck to Ilzepi on this interesting project!
