|
Definition
|
|
Term
|
Definition
•TEETH AND FILM ARE PARALLEL TO EACH OTHER •CENTRAL RAY OF THE X-RAY IS PERPENDICULAR TO BOTH THE TEETH AND THE FILM •THERE IS LESS DISTORTION IN PARALLELING WHICH GIVES A TRUER INDICATION OF BONE LEVELS |
|
|
Term
|
Definition
•FILM IS AS CLOSE TO TEETH AS POSSIBLE AND CENTRAL RAY IS DIRECTED TO AN IMAGINARY LINE BETWEEN THE TOOTH AND THE FILM •CAUSES DISTORTION AND EXAGGERATION OF BONE LEVEL •NOT RECOMMENDED FOR PERIO DIAGNOSIS |

CONVENTIONAL RADIOGRAPHS (PERIAPICAL, BITEWINGS, PANO) USED IN PERIODONTICS: |
|
Definition
•GIVE A HISTORY OF PAST PERIO DESTRUCTION, BUT NO INFO ON CURRENT PERIO STATUS •REPRESENTS A 2D VIEW OF A 3D OBJECT |
|
|
Term
BITEWINGS ARE THE BEST RADIOGRAPH TO INTERPRET: |
|
Definition
•POSTERIOR ALVEOLAR BONE LEVELS •BONE LOSS WITH THE LEAST AMOUNT OF DISTORTION OR TECHNIQUE ERROR |
|
|
Term
|
Definition
•SHOWS THE ENTIRE DENTITION AND SUPPORTING BONE STRUCTURE FROM CONDYLE TO CONDYLE •DOESN'T HAVE THE SAME DEGREE OF DEFINITION AS INTRAORAL •VERY LIMITED VALUE IN DIAGNOSING PERIO DISEASE |

LIMITATIONS OF USING RADIOGRAPHS TO RECOGNIZE PERIODONTITIS: |
|
Definition
•THEY ONLY SHOW PAST DISEASE ACTIVITY •IN ORDER FOR BONE LOSS TO BE IDENTIFIED ON A RADIOGRAPH, ABOUT 30-50% LOSS OF MINERALIZATION MUST OCCUR |
|
|
Term
WHAT DOES BONE LOSS LOOK LIKE ON A RADIOGRAPH? |
|
Definition

HOW DO YOU DETERMINE BONE LOSS? |
|
Definition
•DRAW A LINE CONNECTING ADJACENT CEJs •IF THE ALVEOLAR CREST IS MORE THAN 2mm APICAL TO THE CEJ, THERE IS BONE LOSS |
|

Definition
•2:1 •IT IS IMPORTANT IN PROSTHODONTICS |

Term
HOW DO YOU DETECT MILD PERIODONTITIS ON A RADIOGRAPH? |
|
Definition
•SLIGHT CHANGES IN THE ALVEOLAR CREST •TRIANGULATION (WIDENING OF THE PDL SPACE AT THE CRESTAL AREA) |

Term
HOW DO YOU DETECT MODERATE PERIODONTITIS ON A RADIOGRAPH? |
|
Definition
•BONE LOSS MAY BE APPARENT IN BOTH HORIZONTAL AND VERTICAL PLANES •RADIOLUCENCIES APPEAR IN FURCA AREAS • DIFFERENCE IN DENSITY INDICATES DIFFERENT LEVELS OF BONE ON BUCCAL AND LINGUAL SURFACES |
|
|
Term
