Abstract

CBCT replace the use of conventional radiographs in many fields in nowadays dentistry.
Aim:
Measuring the accuracy of the two CBCT machines in detection of periodontal defects.

Material and method:
With its small field of view Planmecca 3D machine was used in detection of fenestration and dehiscence periodontal defects around anterior, premolar and molar teeth and a control group were done. They were made on human mandibles and maxillae made by using dental drills with high coolant. The studied bone was covered by soft wax as soft tissue simulation and the selected voxel sizes were used. Real measurements were done by graded periodontal probe to the nearest 0.5 mm. Radiographic measurements were done by measurements of CBCT software. Were there no restricted time for evaluation was chosen. The resulted measures were compared statistically.
Results:
No statistical difference between the radiographic measurements and on-skull measurement was detected.
Conclusion:
CBCT is important tool in measurements for fenestration and dehisence periodontal defects.
