BACKGROUND
The described invention belongs to the field of Oral Health Education and promotion. As we all know an ounce of prevention is worth a pound of cure. Oral Health promotion is considered the first step in the prevention against oral disease. It gives people the knowledge and power to protect themselves against oral diseases (like dental decay and periodontal disease) through modifications in their everyday activities and habits.
Oral health promotion is a feasible way for the alleviation of the physical, psychological and financial burden of oral disease from the individual and from society.
Some challenges exist in the way of spreading such preventive movements. Among those challenges is the scarcity of educational tools that make the scientific information conveyed simpler and more adaptable.
In this description we present“KD Senna Flat”. An education tool that helps explaining and showcasing the nature of dental decay.
SUMMARY
The presented invention is a structured use of a classic acid base reaction to better explain how dental decay happen.
Our research lead us to know that there is no previous publication or registration about a similar invention.
What could be found is a simple use of the acid-base reaction in the“KD Senna Flat” to mimic an amplified fastened version of the reaction that naturally causes dental decay. Any other use of this reaction will be a simple improvised model that lacks the sophistication explained below in the description of the KD Senna Flat.
An acid base reaction as explained in Britannica encyclopedia, written by Ronal Percy Bell in November 2018:
“Acids are chemical compounds that show, in water solution, a sharp taste, a corrosive action on metals, and the ability to turn certain blue vegetable dyes red. Bases are chemical compounds that, in solution, are soapy to the touch and turn red vegetable dyes blue. When mixed, acids and bases neutralize one another and produce salts, substances with a salty taste and none of the characteristic properties of either acids or bases.”

DETAILED DESCRIPTION
The design of the invention is based on 3 main pillars:
1. The box structure and its external design (Figure 1 )
The box takes the shape of a rectangular cuboid with dimensions varying from 5*5*2 cm to 100*100*30 cm (Figure 1 ).
The box is manufactured out of paper or carton paper, recycled paper or plastic.
A hole exists on the front surface of the box in the shape of a circle within it a star shaped opening (6) that allows pulling the gloves out of the box during the use of the tool.
A path of opening is integrated int eh box’s structure. A partial cutting giving the impression of a“paper zipper” exists from one side of the box passing through the other side (4). This“paper Zipper” allows its opening in a predetermined way (180 degrees like a book) as seen in (Figure2).
The external design on the front surface of the box (2) showing a drawing of the invention’s logo and name. The side of the box has drawings of the content of the box (1). While the other side has the name of the invention printed on it (3). The back surface of the box has some instructions on how to keep healthy teeth (5)
2. The box transformation when opened and internal design (Figure 2)
When the box is open, it is transformed into a paper base on which the experiments can be done. On the internal surface of the box (7,8) some printed materials exist explaining the steps to do the experiment and a simple scientific background. Using drawings and words to be comprehensible for those who can read and those who can’t.
The box is packed from the upper surface and then closed during packing, to be opened using the“paper zipper” (4) by the user.
3. The tooth model and experiment tools (Figure 3, Figure 4, Figure 5)
The tooth model (figure 3) is manufactured out of carving/casting either Styrofoam, paper, carton reinforced paper or recycled paper pulp or plastic.
The tooth model is given the wanted size that ranges between 5*5*2cm up to 100*100*30 cm.
Afterwards the area representing the tooth’s crown (9) is painted in a dark color, when it dries off, it is painted with the prepared calcium carbonate-based material mixed with tap water with the appropriate number of layers to cover the dark color underneath and mimic the feel of the hard-smooth natural tooth surface. • The acidic fluid is made of acetic acid concentration between 4-6% with a safe color added to it and then packed in a small container (Figure5). The needed number of containers is added inside the“KD Senna Flat’ box.
• The gloves: A pair of plastic or nitrile gloves is added in the box to keep
hands clean and to add excitement to the experiment. There is no protective value as the materials used are totally safe and are all registered and licensed to be sold directly to the consumer.
• A piece of cloth: Used to dry the fluid after the experiment is done. The
appropriate number is added to each box to be used by the user.
• Reconstruction material: (Optional component) a small quantity of baking flour is used to create a small piece of dough to replace the hole created in the tooth. The difficulties in doing so are used to explain why we must protect our teeth.
The method of use of the“KD Senna Flat” box:
Step 1 : The gloves are drawn out of the box through the special circular hole (6), exactly like pulling paper tissues out of their box.
Step 2: The box is opened through pulling the“Paper zipper” from the start point, shown on the box to the end point, also shown (4). The box is fully open 180 degrees
Step 3: The user holds the tooth model (Figure 3) and places it on the grey area printed on the inner surface of the box (Figure 2)
Step 4: The user reads the instructions printed inside the box (7,8) or hears the instructions from the educator or trainer in charge.
Step 5: The user holds the acidic fluid container (figure 5) and opens it. Slowly he spills the content of the calcium carbonate-based material covering the crown (9) of the tooth model (Figure 3). Suddenly the chemical reaction accompanied by the effervescence happens.
Step 6: The user holds a piece of cloth from the box and wipes the resultant reaction product. He sees clearly that the calcium carbonate layer developed a small surface discontinuity mimicking the development of the dental decay on the surface of normal teeth but amplified and fastened to be perceived by the eyes.
Step 7: repetition of step 6 as many times as wanted to see the reaction and
comprehend it.
Extra step: (When available) The user can create a small piece of dough with the baking flour and water and tries to fill the small surface hole with this dough. The difficulties encountered while doing so are part of the explanation of why protecting the teeth from decay is very important. Step 8: The user takes of the gloves an throws them in the garbage with all the used experiment tools. The user keeps only the tooth model (figure 3) and the empty box (figure 2) with him.
Step 9: Turning the back of the box (5), the user chooses which steps he/she would like to commit to, in order to maintain a healthy mouth and teeth.
The potential use of the invention:
The invention is used as an educational tool to explain practically how dental decay happens. This information is important to explain and understand how to protect our teeth from dental decay.
The areas and fields that could benefit from this invention are:
• Every place providing health care service, can provide oral health promotion using the invention.
• The field of education, schools, nurseries and even universities.
• All training fields of adults can use the invention for better explanation during oral health care.
The users could come from any age group or background:
• Kids in nurseries
• Children and young adults in schools
• Children and young adults in different social care facilities
• Companies and institutions for oral health promotion for the employees
• Hospitals for oral health promotion of patients and staff
• Primary health care units in remote areas for oral health promotion.
The design and printed material on the invention make it usable and understandable by the general population in any training setting, without the need of a trainer with an oral health science background. Although it is preferable.
