Early handpiece design was ergonomically modified

 

Although the next generation of ultrasonic probes are much more advanced than previous designs, it is straight and bulky, especially in the back of the mouth. In addition, the required equipment includes a computer running detectors, monitor, keyboard, independent electronic box to control the water pressure, and a foot pedal is installed in a big car not convenient transportation. In the next few years, researchers, engineers and clinicians are working to the ultrasonic probe refined into a kind of light weight, smooth, with a comparative perspective of hand pieces, with standard dentin quick disconnect and flexible pipes.computerized ultrasound dental instruments are smaller, easier to transport, and have the chairman of clinical trials.
The ultrasonic probe beams a very narrow band of high-frequency (10-15 MHz) ultrasonic beams into the gums, and then detects the echoes back from the tissue. The sensor mounted on the tip of the probe can install a small amount of water from the dental chair to ensure good coupling between ultrasonic energy and tissue. When the pedal is activated, a narrow band of ultrasonic energy is projected into the groove, passing through the tip of the probe as it slowly travels along the gingival edge. The focused ultrasound beam is transmitted to a groove in the same direction as the manual probe, although the probe itself does not penetrate the tissue.
Unlike artificial detection, in 6 parts per tooth measured values, the tip of the ultrasonic probe was placed on the edge of the gums, gently until slight blanch, then area swept along the gums. The ultrasonic probe is able to capture a series of observations (depth measurements and Outlines) painlessly throughout the gingiva region, as the tip of the probe passes along the gingival edge, producing more information.
Clinical trials
A concept study was conducted to compare ultrasonic probes with computer-controlled pressure probes and non-c-12 artificial probes. At baseline, detection techniques, manual (M), constant force (CF), and ultrasound (we), are in 12 participants. After 1 hour, the whole mouth was detected. The interval is long enough for the examiner to report, but short enough to capture the same gum assessment. The treated quadrants and detection methods are randomly assigned. In order to reduce the change of the examiner, a single, experienced, calibrated research hygienist is used for all data collection. During the electronic data collection process, the inspector was not allowed to view the monitor screen while the assistant recorded all manual detection readings. At the start of the appointment, use the gum index of "love" and "Silness" to assess the severity of the gingival tissue adjacent to the selected tooth, and score from 0-3 according to the amount of inflammation presented.
The tip of the ultrasonic probe is placed in a vertical position parallel to the long axis of the tooth. Gently place your fingertips on the edge of your gums until the gum is slightly bleached to ensure that the water is completely combined with the gum groove and then use the pedal to activate the probe. When the pedals are in use, a small stream of water will flow into the ditch, plus an ultrasound. When the sound waves rebound from the periodontal tissue, the echo is recorded by a tiny sensor and analyzed simultaneously with the computer of the ultrasound device. When the examiner to the tip of the probe by the edge of the gums, computer records the input data, these data by using artificial intelligence algorithms to output data can be converted to mm for the estimation of the units of the detection depth.
Compare CF probes with a thin soft fiber and gently insert into the groove. The data is captured as an optical encoder in the handpiece scan, and how much filament is left in the groove as an indicator of probe depth at the contact point. M probes are used in a traditional manner. The depth of the pockets of the M and CF probes were measured in six places. As a result, 162 teeth provided 972 independent measurement values for different degrees of periodontal health.
The detector data is continuous, therefore, preliminary results suggest that more probe probe measurement and CF (M) and the United States the different characteristics of the channel, the result is not obvious, how to correspond to measurement results. M and CF detection methods, however, is through the resistance of adhesion epithelium to measure the depth of a groove, and the probe measurement is more likely to correspond to the anatomical characteristics, such as calculus, bones or connective tissue attachment.
conclusion
Ultrasonic probe is probably one of the important traditional manual periodontal probing alternative, because it is a non-invasive, painless, not easy to be detected, may be more sensitive, may generate additional histologic information. However, more research is needed to verify these claims. Issues such as research and development costs and the price of bringing new products to market have played an important role in the development, production and adoption of new ultrasonic detection technologies.
With the success of ultrasound imaging in medicine, the application of ultrasonic dental equipment technology in the dental field is particularly promising. With the development of ultrasonic technology, researchers still hope that current research will provide information necessary for further development of existing applications. Non-invasive ultrasound commitment with a probe of periodontal disease, will not endanger the ditch the integrity of the histology and is likely to get more real time information, thereby eliminating the traditional manual detection of many defects, so as to promote periodontal evaluation.
