Common diseases
of teeth and
supporting structures
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
1-Dental caries
Factors affecting interpretation
of dental caries
1-Errors in vertical and horizontal
angulation
2-Cervical burn out
Types of dental caries
1-Interproximal caries
2-Occlusal caries
3-Secondary caries
4-Buccal and lingual caries
5-Root caries
2-Pulp exposure
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
2-Incomplete root formation
Periapical
granuloma cyst abscess
Periapical granuloma
Periapical cyst
Periapical abscess
1st stage of cementoblastoma
4-Periodontal space thickening
Peridontal space thickening
1-Pathological (tooth extrusion,root,lamina dura
resorption,trauma,initial symptoms of
osteomylitis)
2-Non pathological (terminal stage of root
formation)
Periodontal space thickening
1-Pathological (tooth extrusion)
Root and lamina dura resorption
5-Root end changes
1-hypercementosis
Root resorption 1-internal root resorption
2-external root resorption
3-apical root resorption
7-Bony changes
associated with apical
alteration
Condensing oseitis
ankylosis
Bone resorption
Vertical bone loss
Horizontal bone loss
8-Pulp calcification
Pulp stone
Secondary dentin
9-Root fracture
Local irritating factors
Abrasion
Cervical burn out
