46
Anodontia
Missing teeth
47
Supernumerary
Extra teeth
48
Dens in dente
Tooth within a tooth
49
Main cause of anodontia
Congenitelly missing teeth
50
Hypercementosis
Excessive cementum formation
51
52
Dilaceration
Sharp bend in root usually in premolars
53
Taurodontia
A tooth normally a mandubular molar with a very large pulp chamber and very short roots
54
Gemination
A single tooth but divides into two teeth. This is not the fusion of two teeth
55
Fusion
Two teeth joined or connected almost always at the crown
56
Concresence
When the cementum of 2 adjacent teeth is joined or fused. Appears as overlapping roots
57
Dentinogenesis imperfecta
Malformation of dentin
58
Amelogenesis imperfecta
Malformation of enamel
59
Periapical abscess
Cause by bacteria that has reached the pulp and cause irreversible pulp damage
60
Granuloma
Granulation tissue that is continuous with the PDL and attached to the root of the apex
61
Cyst
Fluid filled or semi-solid area that appears radiolucent on a radiograph
62
Forms of cysts include
Dentigerous cyst
Odontogenic cyst
Nonodontogenic cyst
63
Dentigerous cyst
Most often with supernumery teeth but also with impacted teeth
64
Odontogenic cyst
Includes cyst formed because of a tooth so may be periapical, residual, dentigerous.
65
Nonodontogenic cyst
Any cyst not arising from a tooth
Includes incisive canal cyst (nasopalatine) and globulomaxillary cyst located between the lateral and canine
66
Odontogenic tumors
Formed by an abnormal proliferation of odontogenic cells (cells that form teeth)
67
Ameloblastoma
Large radiolucient area of enamel origin with mono or multilocular (many compartments) that gives a soap bubble appearance - quite rare
68
Odontoma
Most common and is a small mishapened mass of teeth radiopaque with a radiolucient fibous capsule resembling a cyst
69
Cementoma
A cementifying fibroma usually on mandibular anteriors in women and require no treatment
70
Tooth resorption
Primary teeth undergo in response to erupting permanent teeth
71
Retained roots
Very common on radiographs caused by: Primary tooth root tips, crown has decayed completely away, dentist left in extraction
72
Calcifications
Pulp stone
Sialoliths
Rhinoliths
Phleboliths
73
Sialoliths
Salivary stones that are deposits of calcium salts in salivary glands or ducts
74
Rhinoliths
Stones in the maxillary sinus
75
Pheboliths
calcified thrombi in soft tissues usually the cheek
76
Ossifications
Condensing osteitis
Osteosclerosis
77
Condensing osteitis
The sclerosis of hardening bone as a result of infection
78
Osteosclerosis
Abnormally dense bone not a result of infection
79
Carcinoma
Of epithelial origin
80
Sarcoma
Of connective tissue origin - produce a change in bone early on with a patchy appearance
81
Exostosis
Localized overgrowth on bone such as a torus or tori that may occur on the hard tissue of the palate or the lingual surfaces of the mandible
82
Fractures
Appears as thin RL lines similar to nutrient canals - May or may not line up bone to bone
83
