Sealants Flashcards
Histology of Dentin
70% inorganic, 30% organic matter, and water. Calcium and phosphorus are chief inorganic
Histology of Pulp
Pain receptors, blood vessels connective tissue dental papilla
Histology of Cementum
55% organic material, 45% inorganic material
Histology of Periodontal Ligament (PDL)
Dense connective tissue
Histology of Alveloar Process
Bony part of jaw that roots are supported through
Cusp
A pointed or rounded elevation of enamel found on cuspids and on chewing surfaces
Cingulum
On lingual of anterior teeth. A convex mount of enamel localized on cervical
Fissure
Linear fault in groove formed by incomplete or imperfect love joining
Fossa
A rounded depression into a tooth found on the surface
Pit
Groove of a tooth
Supplemental groove
Minor, auxiliary groove branching off from more prominent grooves
Developmental groove
A small linear depression on a tooth surface
Triangular fossa
Adjacent to marginal ridges of occlusal surfaces
Marginal ridge
Linear rounded border of enamel forming on mesial and distal margins/borders
Hypodontia
Missing 1 or more teeth
Hyperfontia
Supernumerary teeth
Microdontia
Teeth smaller than average
Macrodontia
Teeth larger than average
Gementation
Development of 2 tooth crowns from one tooth gem
Fusion
Union of 2 adjacent tooth gems by dentin during development
Dens of dente
When focal areas of maximally lateral incisors are folded inward
Enamel hypoplasia
Incomplete enamel formation/maturation affecting teeth
Amelogenesis imperfecta
Hereditary disorders of enamel formation producing hypoplastic enamel in primary and permanent dentitions
Dentinogenesis Imperfecta
Inherited disorder results in a bluish discoloration of teeth crowns and flaking of normal overlying enamel
