RADIOGRAPHIC DIAGNOSIS OF SYSTEMIC DISEASES MANIFESTED IN THE JAWS DR ARISHIYA THAPASUM SCOPE OF THE LECTURE ‡Systemic diseases can have oral maxillofacial and radiographic changes. ‡General dentists are likely to encounter one many of systemic diseases that present withand oral maxillofacial radiologic changes. ‡This lecture will serve as a eye opener to various manifestations of systemic diseases (Clinical, General manifestations in other bones & exclusively in the jaws) CONTENT OF THE LECTURE ‡ ENDOCRINE DISORDERS ‡METABOLIC BONE DISEASES ‡ OTHER SYSTEMIC DISEASES APPLICATIONS OF DIAGNOSTIC IMAGING MAJOR IMAGING CHANGES TO BONE WITH ENDOCRINE AND METABOLIC BONE DISEASES. ‡1. CHANGE IN SIZE AND SHAPE OF THE BONE ‡2. CHANGE IN THE NUMBER, SIZE, AND ORIENTATION OF TRABECULAE ‡3. ALTERED THICKNESS AND DENSITY OF CORTICAL STRUCTURES ‡4. INCREASE OR DECREASE IN OVERALL DENSITY BONE ‡5. CHANGES TO THE BONE CORTEX OR TRABECULAE CAN RESULT IN A DECREASE INCREASE OR IN BONE DENSITY. EFFECTS ON TEETH AND ASSOCIATED STRUCTURES ‡1.
