Study Notes
Dental and Developmental Anomalies
- Anomaly: Deviation or inconsistency from the normal.
- Number of Teeth:
- Hyperdontia/Supernumerary Teeth: Excessive teeth.
- Mesiodens: Extra tooth commonly found between central incisors.
- Hypodontia: Missing teeth.
- Oligodontia: Missing multiple teeth.
- Anodontia: Absence of teeth.
- Size of Teeth:
- Macrodontia: Teeth larger than normal.
- Microdontia: Teeth smaller than normal.
- Eruption or Position of Teeth:
- Impaction: Tooth unable to erupt.
- Transposition: Teeth switch positions.
- Ankylosis: Tooth fused to the bone.
- Ectopia: Tooth in abnormal position.
- Morphology of Teeth:
- Gemination: One tooth divides into two.
- Twinning: Two teeth fuse together.
- Fusion: Two teeth fuse together.
- Concrescence: Roots of two teeth fuse together.
- Taurodontism: Elongated pulp chamber in molars.
- Dens Invaginatus: Invagination of the crown.
- Dens Evaginatus: Outward folding of enamel organ.
- Dilaceration: Irregular curvature of tooth.
Congenital and Acquired Conditions
- Congenital: Conditions present at birth. May be hereditary or environmentally influenced.
- Acquired: Conditions developing after birth. Often environmental in nature.
Number of Teeth (Anomaly Detail)
-
Hyperdontia/Supernumerary Teeth:
- Premolars: Most common site in the mandible.
- Generalized: Extra teeth in multiple areas.
-
Mesiodens:
- Commonly in the space between central incisors.
-
Diseases Associated with Supernumerary Teeth:
- Cleidocranial Dysplasia: Least severe condition; involves skull, clavicle, and supernumerary teeth.
- Gardner's Syndrome: Individuals may have polyps in large intestines (100% chance of turning malignant), along with multiple osteomas and supernumerary teeth.
- Hypodontia: Missing one or a few teeth. Most common missing:
- Maxillary lateral incisors (most common)
- Third molars
- Second premolars in mandible
- Maxillary lateral incisors
- Mandible central incisors
-
Oligodontia: Missing more than six teeth.
-
Anodontia: Missing all teeth.
Size of Teeth
- Rule Outs: Positioning errors in panoramic x-rays; supernumerary teeth; irradiation to jaws causing dwarfing of teeth
- Macrodontia: Teeth larger than normal (usually impacts only one tooth). May occur with rare conditions.
- Microdontia: Teeth smaller than normal (mostly affects only one tooth). May occur with rarer conditions.
Eruption or Position of Teeth
Tooth that fails to erupt:- Commonly identified in Canines and molars.
- It can be due to bone or soft tissue impaction.
Morphology of teeth
Gemmination:Clefting or invagination of the crown. A single pulp may be enlarged or partially dividedFusion:Two teeth fused together. If there is no PDL space between the two teeth it could indicate fusion.Concrescence:The roots of two teeth fused together by cementum
Taurodontism
- Molar shaped like a bull.
- Large "trunk"- extension of the pulp
- Short roots
- Wide Pulp chambers
Dilaceration
- Sudden change in direction of tooth.
- Extreme root or tooth curvature.
Other anomalies
Ankylosis:Tooth fused to the bone.Ectopia:Abnormal position of tooth.
