Even if children lean the right toothbrushing by dental camp, the dental calculus (dirt) attached druing the past cannot be removed easily.
The dirt which adhered to the tooth becomes hard like a sand(= dental calculus).
Scaling can remove it.
But We cannot say "Just delete it!."....
Moreover, excessive medical intervention without proper health education sometimes spoil the preventive medical/dental project !
It may cause the underestimate for toothbrushing! The prevention should be done by themselves.

Goggles, surgical masks and (basically) disposable goggles.
Also,
1) Bacteria and virus may invade into the body from gum (gingiva) at scaling.
2) It may cause an opposite effect when toothbrushing was not done properly.
3) We must avoid damaging milk teeth, an incomplete root, and a child's weak periodontal tissue.
4) Since the danger of infection is higher than that of toothbrushing instruction, disinfection of tools(tips) should be done seriously.
Also our team must use infection protection tools.(The prevalence of tuberculosis is much higher thanthat of Japan.)

And above all, We must reduce the required time and physical strength for both children and us considerably.
So, we will use an ultrasonic scaler(Painless and easy) and are making some provisional guidelines.
1) Target/object -- the 5th grade (the last grade)students who already learm proper toothbrushing.
2) Healthy children .
3) Children who have done toothbrushing well (checking by dental plaque dyeing) .
4) Maximun 16 Children at one Dental Camp.
5) From the aspect of technical limitation.
5-1) Only the supragingival calculus of permanent tooth.
5-2) Using only soft type chips.
5-3) 16 sterilized tips. One tip for one child. (Disinfection at schools will be impossible.)
5-4) An output should be the minimum P Mode.
5-5) Prevention measures against of infection from children.
** A guardian's consent is indispensable!

One the other reson is ,,,,
sometimes we face question by the local people that why we don't provide any curative management?
This Low/Non invasive scaling and ART will solve the questions.
These methods are None/Minimum invasive and,above all, can enforce the preventive effect of tooth brushing.

Unexpectedly, the children's dental tartar(calculus) already became hard!.
So with a soft type chip, it is too difficult to remove hard dental tartar!
In addition, in order to remove these hard tartars, it takes more time. (Since there is only one unit of US scaler, scaling for just three children is utmost possible in a previous dental camp.)
Originally, we should focus on toothbrushing, but without carrying out scaling and ART;, many tooth will disappear certainty.
Some reviews of the strategy will be required.
There are limits to the use of expensive equipment.
It may be necessary to consider the use of hand scalers.


US Scaling by Prof.Khursiduzzaman using hard chips
There are so many removed dental calculus and bleeding from gum!

Tips of tip..
Be careful about the direction of Tip to the surface of tooth!. P-mode and MINI. power at start! Please do not use S or E mode for Soft-tip!

Caution: Never use S or E mode for Soft-tip! Only P-mode P1-P3! Or.....!


Metal hard tips or hand-scalers will be useful to remove hard dental calculus under deep pocket.


Chair and Suction apparatus were also needed.
Pain control and infection control (precautions against infectious for the operator. Bleeding,) are also important. (This Portable chair for Dental Camp With suction apparatus were prepared by Dr.Haider)
