Use of Radiographic Contrast to Detect Dental Caries

NCT01523509 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 33

Last updated 2016-06-17

No results posted yet for this study

Summary

The proposed test is intended to enable dentists to differentiate between cavitated and non-cavitated tooth decay in the areas where teeth are in contact (interproximal surfaces). In these areas, dentists cannot visually inspect for caries, and currently bitewing X-rays (BWs) only correctly detect the presence of enamel decay 15-25% of the time. This low sensitivity can lead to late treatment resulting in unnecessarily large fillings, crowns, pain, root canals, and possible later loss of teeth.

Hypothesis: Use of radiographic contrast on teeth will increase the accuracy of detection of early cavitation from 58% to 90%.

Conditions
