Transcript of 5-11-2018 Common diseases - University of Babylon
1-Dental caries
2-Pulp exposure
3-Periapical radiolucencies
4-Periodontal space thickening
5-Root end changes
6-Bone changes
7-Root resorption
8-Pulp calcification
9-Tooth fracture
10-Erosion,Abrasion,Attrition
3-Periapical radiolucencies
Common pathological condition
Granuloma
Cyst
Abcess
1st stage of cementoblastoma
Radiographical signs
1-interrupted lamina dura
2-periphery blend into surrounding bone
3-definite demarcation between lesion and bone
4-lesion exhibit distinct bone lamina encircling the radiolucency shape
5- the radiolucency shape is basically spherical with irregular or smooth out line periphery.
Interpretation of periapical radiolucencies
1-Superimposition of normal anatomical landmarks like
mental foramen, maxillary sinus, inferior alveolar canal
Peridontal space thickening
1-Pathological (tooth extrusion,root,lamina dura
resorption,trauma,initial symptoms of
osteomylitis)
2-Non pathological (terminal stage of root
formation)
Root resorption 1-internal root resorption
2-external root resorption
3-apical root resorption
