Dexis-Intraoral Digital Dental X-Ray Sensor

Sensor Comfort and Ease of Use

According to DEXIS, the heart of their digital system is the PerfectSize sensor. The manufacturer states that their single-size sensor has 3 advantages:

1) because the electronics are on the back of the sensor, the active imaging area is most of the total sensor size;

2) the beveled corners, slim profile, and rounded casing allow for accurate placement and patient comfort;

3) patented cord placement allows the practitioner to take vertical and horizontal bitewings and all periapicals with only 1 universally sized sensor. The evaluators were asked to rate both the ease of use of the sensor and patient comfort. Five evaluators rated ease of use excellent and 4 rated it very good. With regard to patient comfort, 3 evaluators rated the sensor excellent and 6 rated it very good. One evaluator noted that he experienced a few issues when placing the sensor in some children and patients with very small mouths. Another evaluator, however, is very happy with the sensor, saying, “I chose DEXIS to take a full radiographic series on every patient. It was the only direct image system we tested that met that objective.”
