Odontomes
- = Harmatomas
- non-neoplastic, non-infective
- limited growth potential
- Developmental malformations
- Enamel pearl
- often at furcations
- Cause = disruption in
Hertwig's root sheath
- Plaque retentive ->
localised perio disease
- Invaginated odontome
- Dens in dente = tooth within a tooth
- Most common in
cingulum of 2s
- weak enamel -> pulpitis
- Evaginated odontome
- often presents as extra cusp
- = talon cusp in anteriors
- Most common in
Mongolians & Premolars
- weak enamel -> pulpitis
- Complex odontome
- Irregular mass of all the tooth tissues
- Presentation
- Asymptomatic
- Unerupted tooth
- Most common
- Pain, swelling, cyst formation
- Well-defined radiolucent zone/outline,
radiopaque centre
- Site
- Mandible > Maxilla
- Molar region
- Effects = impede
eruption, displace teeth,
cortical expansion
- Compound odontome
- Composed of denticles (bag of teeth)
- Nomal tooth structure (pulp
within dentine within enamel)
- Site = Maxillary canine region
- Treatment = curretage out
