hypercementosis
- excess cementum
- after eruption
- trauma
- permanent molars
cementoma

- destruction of bone
accessory roots and cusps
- extra roots and cusps
- third molars
- cingulums of anteriors
talon cusp
-grow out of cingulum in anteriors
enamel pearls
- enamelofma
- dentin in core
- spherical shape
- furcation areas of permanent molars
- increased risk of periodontal disease
cervical enamel extension
-enamel continues on to root surface
hutchinson’s incisors
- enamel didn’t form
- syphillus prenatal
- screwdriver shaped
mulberry molars
- prenatal syphillus
- first molars
odontoma
- calcified tissue
- benign tumor
- disturbance of dental lamina caused by trauma or infection
- blob=complex
- rough tooth shape=compound
globodontia
- lack cusp ridges
- globe shaped
- round
taurodontism
- bowl like tooth
- enlargement of pulp chamber
- crown look normal but short roots
- lack of cervical constriction
enamel dysplasia
- disturbance during enamel development
- severity depends on how long disturbance lasted and stage it was in
enamel hypoplasia
- enamoblasts injury during enamel matrix formation
- deficient matrix
- ridges of enamel
- caused by inflammation or high fever
- enamel laying down
enamel hypocalcification
- enamel maturation
- disturbed calcification (does not completely calcify)
- white spots
regional odontodysplasia
- ghost teeth
- enamel so calcified it flaked off
- so thin teeth won’t erupt
amelogenesis imperfecta
- enamel matrix
- no enamel or enamel deposited and doesn’t calcify
- yellow/brown enamel
- thin, pitted, various prone
- teeth worn down
- stained
dental fluorosis
- excessive fluoride
- during enamel calcifying
- caries resistant
- chalky white turns brown from staining
focal hypomaturation
- white chalky area
- localized, circular
- trauma to deciduous tooth affects developing tooth bud/germ
- enamel is soft
- prone to caries, staining
turner’s teeth
- injury to tooth bud
- browning, pitting, discoloration
- depression, not smooth
tetracycline staining
- antibiotic for pregnant women for infections
- effects teeth of developing child
- got deposited, staining teeth
- extent depends on developing stage of baby and how long mother was on antibiotics
dentinogenesis imperfecta
- genetic
- dentin formation
- normal enamel falls off because no good dentin underneath
- crown blue/brown color
- severe attrition
dentin phyoplasia
- calcification of dentin affected by disturbance
- enamel can’t adhere and falls off
interglobular dentin
- blobs of dentin
- hypocalcified
- crown or root
