Dental anomalies
Are deviations of dental tissue origin—
Dental tissues are enamel, dentin or cementum

These anomalies can result from:
Intrinsic factors
Extrinsic factors

Intrinsic factors
Result of heredity, metabolic dysfunction, or mutations

Extrinsic factors
Result of physical or chemical trauma, biologic agents, nutritional deficiencies, stress, habits or environmental conditions.

Hereditary
Congenital—condition that occurs at or before birth
Familial tendency- if a condition exists due to evidence of an inherited tendency
Developmental anomaly- a condition that results during the formation and development of a dental structure.

Classification of Dental Anomalies
Macrodontia-teeth are too large
Microdontia- teeth are too small
Hyperdontia- extra teeth
Anodontia- too few teethTotal anodontia- no teeth are present at all
Partial anodontia- less than the normal number of teeth are present.
![Page 8: DENTAL ANOMALIES Anomaly- defined as something that is noticeably different or deviates from the norm.](https://reader035.fdocuments.us/reader035/viewer/2022062404/551a2381550346cb358b4bbd/html5/thumbnails/8.jpg)
Most common missing permanent teeth are:
Third molars
More often the maxillary thirds more than the mandibular thirds.

Second most common missing permanent teeth are:
Maxillary lateral incisors
![Page 10: DENTAL ANOMALIES Anomaly- defined as something that is noticeably different or deviates from the norm.](https://reader035.fdocuments.us/reader035/viewer/2022062404/551a2381550346cb358b4bbd/html5/thumbnails/10.jpg)
Third most common missing tooth is:
Mandibular second premolar
![Page 11: DENTAL ANOMALIES Anomaly- defined as something that is noticeably different or deviates from the norm.](https://reader035.fdocuments.us/reader035/viewer/2022062404/551a2381550346cb358b4bbd/html5/thumbnails/11.jpg)
Least likely permanent tooth to be missing is:
The canines
![Page 12: DENTAL ANOMALIES Anomaly- defined as something that is noticeably different or deviates from the norm.](https://reader035.fdocuments.us/reader035/viewer/2022062404/551a2381550346cb358b4bbd/html5/thumbnails/12.jpg)
Hyperdontia
Supernumerary teeth
![Page 13: DENTAL ANOMALIES Anomaly- defined as something that is noticeably different or deviates from the norm.](https://reader035.fdocuments.us/reader035/viewer/2022062404/551a2381550346cb358b4bbd/html5/thumbnails/13.jpg)
Mesiodens- supernumerary teeth in the midline of maxillae.

Maxillary supernumerary teeth outnumber mandibular.
Shapes of supernumerary teeth:Regular tooth shape- supplemental
Cone-shaped- conical
Very small in size- tubercle

Hyperdontia
Distomolars- are called fourth molars and are located distal to the maxillary third molars.—these occur more frequently in the Maxillary then Mandibular arch.
Paramolar- a supernumerary tooth situated buccally or lingually to a molar.

ANOMALIES IN SHAPE
Odontoma-tumorous anomaly of calcified dental tissues

Dens in Dente
The outer surface of the tooth crown invaginates or turns itself inward before mineralization—
Means, “tooth within a tooth”
