3 AHCJYS Furcations -- maxillary molars Buccal - may be obscured due to superimpostionBuccal - may be obscured due to superimpostion Mesial and distalMesial and distal –The pointer

4 AHCJYS Mesial and distal furcations

5 AHCJYS Mesial and distal furcations

6 AHCJYS Mesial and distal furcations

7 AHCJYS Not a replacement for an examination!!!

8 AHCJYS Limitations Does not show periodontal pocketsDoes not show periodontal pockets Does not show morphology of the defectsDoes not show morphology of the defects Misses buccal and lingual deformitiesMisses buccal and lingual deformities Does not distinguish between treated and untreated caseDoes not distinguish between treated and untreated case

9 AHCJYS Treatment status AfterBefore

10 AHCJYS Treatment status AfterBefore

11 AHCJYS Limitations Does not show periodontal pocketsDoes not show periodontal pockets Does not show morphology of the defectsDoes not show morphology of the defects Misses buccal and lingual deformitiesMisses buccal and lingual deformities Does not distinguish between treated and untreated caseDoes not distinguish between treated and untreated case Does not show mobility Does not show mobility Does not show hard and soft tissue relationships Does not show hard and soft tissue relationships

12 AHCJYS Benefits Can show relationship of crestCan show relationship of crest Can help monitor disease progressionCan help monitor disease progression Indicates areas for further examinationIndicates areas for further examination Documents crown - root ratioDocuments crown - root ratio Evaluation of deposits and marginsEvaluation of deposits and margins

13 AHCJYS Types of surveys Periapical films Bite-wing films – –Horizontal – –Vertical Panoramic filmsPanoramic films CT ScansCT Scans

14 AHCJYS CT Scans

15 AHCJYS CT Scans

16 AHCJYS How Cone Beam CT Works X-ray source Detector ‘Fan’ of X-rays ‘Cone’ of X-rays Detector

17 AHCJYS Effective Dose Comparison  i-CAT 20 second scan:68 uSv Exposure is in “Pulsed” mode, actual exposure time is about 3.5 seconds for a 20 second scan  i-CAT 10 second scan:34 uSv  Daily background:8 uSv  Panoramic (Average): uSv Digital Panoramic4.7 – 14.9 uSv Highest Film Pan26 uSv  Full mouth series:150 uSv  Medical CT uSv*kk Dr. Sharon Brooks, Dept. of Radiology, University of Michigan *Dr. Stuart White, Dept. of Radiology, UCLA
