Always Special attention has been paid to the accurate diagnosis of dental caries in dentistry.
To detect dental caries At the occlusal levels via The perfect mirror And at interdental levels The use of radiographs of Bytewing .
addition to the cost of Preparing radiographs , It expands the patient to x-rays, which itself has multiple complications.
Different radiographic systems are one of the main diagnostic tools in dentistry.
As a result of an increase in the number of illnesses resulting from laser imaging that is the result of this radiation , And the increase in radiation damage to humans.
The best way to detect with 100% accuracy And without zero percentages, To improve the quality of decay detection and Renounce all the problems listed , Decided to design got this device.

The complications and problems of radiographic systems:

**Diseases of the skin and cancer caused by x-rays for dentists and patients
**Physical complications for pregnant women in embryos
**High cost in the preparation and maintenance of radiographic equipment
**Lack of accurate diagnosis of decay (detection of up to 60%) Or the separation of amalgam from the tooth (detecting up to 25%) in the restorative tooth By radiography devices
**Detection of decay (detection 0%) or separation of amalgam substance from the tooth in restorative tooth by oral sensors

** Specific objectives of the project

1. Record the waves from healthy teeth
2. Record the waves from the teeth with 0.5 mm cavities
3. Record waves from teeth with 1 mm cavities
4. Record waves from 1.5 mm cavities
5. Record waves from teeth with 2 mm cavities
6. Compare the two primitive groups together
7. Record radiographs of sample teeth
8. Review the synchronization of radiographic images with the designed model

** Applied Schemes

• Possibility of examining tooth decay in pregnant women and the elderly
• Facilitating the examination of dental caries and studying the separation of amalgam from the tooth in restored teeth ,dont need to go to radiographic centers And exposure to laser radiation (Notably, the most advanced X-ray devices are not able to do it)
• High accuracy of detection than radiography devices up to 100% accuracy of detection
• Cheaper prices, so all dentists will be able to buy this device
• Because of its low cost of service, it does not cost much, and it's a welfare for patients
• Avoiding time to go to the radiography clinic and returning to the dentist's office.

Teeth are randomly divided into 5 groups of 20 teeth. In groups 1-4, cavities at 0.5, 1, 1.5 and 2 depths in the teeth will be created as a decay model. In the fifth group, no cavity will be created. By contacting the ultrasonic probe with the teeth, the waves received by the detector will be recorded.

The next steps are as follows:
1- 3D modeling of the device in Solidworkes 2016 Software
2. Load dynamic forces and dynamic analysis with MC Adams software
3. The loading forces of motion and vibration analysis software ANSYS 17.1
4. Vibration testing of teeth with ME Scope software for comparison with modeling analysis
Next step The teeth are parallel radiographs and the result will be compared with the model. Statistical analysis of data By one-agent variance analysis and The appropriate follow-up is used to compare two-dimensional groups in groups.

At this point, our data will be ready for the device library And the device becomes the program.

The cost of the Intelligent system for detecting tooth decay using piezo vibration and 100% accuracy:

**Making the original model Body with a beautiful look:2500$
**Modal and harmonic vibration testing on 200 human tooth samples ( We will receive from the bank of dentistry of medicin university):19000$
**Build a humanoid robot to move and sit on a dental unit To view system performance :4000$
