Dent. development defects I
Missing or underdevelopment of hair, sebaceous glands, teeth, and sweat glands.
What is Ectodermal Dysplasia?
Soft and weak dentine, enamel chipping and bulbus crowns due to mutation of the DSPP gene.
What is Type II Dentinogenesis Imperfecta?
This is zone of enamel caries have some of the pores smaller than adjacent zones.
What is the Dark Zone?
This has production of exuberant granulation tissue forming a pulp polyp which protrudes beyond the boundaries of the pulp chamber and devoid of sensation on gentle probing?
What is Chronic Hyperplastic Pulpitis?
Teeth united by dentine vs. teeth united at roots by cementum.
What are Connation(fusion, gemination) and Concrescence (false gemination)?
Tooth is severely bent along its long axis.
What is Dilaceration?
Presented with roots composed of dysplastic dentine containing numerous calcified spherical bodies.
What is Type I Dentinal Dysplasia?
This zone of enamel caries is replaced by a broad dark zone in arrested or re-mineralized lesions.
What is the body of enamel caries?
Presented as extrusion of tooth, tender to percussion and less defined lamina dura but no bone loss.
This specific type of Dentinogenesis Imperfecta is associated with Osteogenesis Imperfecta.
What is Type I?
Abnormalities of many bones: a partial or complete absence of clavicles, prominent forehead, underdeveloped maxilla, and delayed or non-eruption of permanent dentition.
What is Cleidocranial Dysplasia ?
Teeth presented with yellow bands of pigmentation at incremental lines in dentine. The pigmented bands fluoresce a bright yellow under ultraviolet light.
What is Tetracycline Staining?
This dental structure regularly forms at the pulp-dentine interface in response to mild stimuli.
What is Reparative Dentine (tertiary dentine)?
Clinical features include trismus and anaesthesia of the lower lip.
Radiograph shows irregular, moth-eaten areas of radiolucency on the jaw.
What is Acute Suppurative Osteomyelitis of the Jaw?
The types of immune cells typically seen in acute periapical periodontitis vs. chronic periapical periodontitis.
What are Neutrophil and T cell?
Ghost teeth: short roots, open apical foramen and irregularly mineralized enamel leading to no distinction between the enamel and dentine.
What is Regional Odontodysplasia?
The hereditary pattern of Dentinogenesis Imperfecta Type I?
What is Autosomal Dominant?
This zone is the earliest and deepest demineralization part of enamel caries.
What is the Translucent Zone?
Localized increase in number and thickness of the bone trabeculae at the apex of a tooth.
What is Focal Sclerosing Osteomyelitis of the jaw?
Irregular resorption of bone and root giving it rough appearance vs. round, smooth radiolucency at root apex.
Anomalous tubercle or Talon cusp located at the center of the occlusal surface.
What is Den Evaginatus?
What is Amelogenesis Imperfecta?
This is formed by the broken-down intervening matrix dentine by acidogenic and proteolytic bacteria in dentine caries.
What is Liquefaction Foci?
Presented as severe pain developing a few days after tooth extraction, bone exposed to saliva.
What is Alveolar Osteitis?
Presented radiographically as a focal subperiosteal overgrowth of bone with a smooth surface on the outer cortical plate.
What is Garre's osteomyelitis?
