Question Answer
what is more common: Internal Resorption or External Resorption?External Resorption
The PDL is responsible for _____ resorptionExternal resorption
The pulp is responsible for _____ resorptionInternal resorption
Well-defined internal resorption is (inflammatory/Replacement) internal resorptionInflammatory
Less well defined internal resorption is (inflammatory/Replacement) internal resorptionReplacement (aka metaplastic)
(inflammatory/Replacement) internal resorption: pulpal dentinal walls are resorbed and replaced with bone or cementum-like bonereplacement
(inflammatory/Replacement) internal resorption: well-circumscribed symmetric radiolucent enlargement of pulp chamber or canal; original outline of canal is lostInflammatory
How do we treat internal resorption?root canal
Moth-eaten appearance of root with clearly delineated and unaltered canal outline is what type of resorption?external
define: loss of tooth structure due to tooth-totooth contactAttrition
normal curved tooth surfaces on radiograph appear flattened... altered into flat planes this suggests what?Attrition
Loss of tooth substance by a chemical process with no known bacterial actionErosion
pathologic wearing away of tooth structure by a mechanical processAbrasion
Loss of tooth structure due to flexure induced by occlusal forcesAbfraction
what is the difference between manifestation of enamel hypoplasia due to medication use and amelogenesis imperfecta?In medicine caused hypoplasia... only teeth that were forming enamel at time of use are affected... (amelogenesis imperfect is global)
affected enamel of incisors and first molars that Has been linked to frequent use of antibiotics in early childhoodMolar-Incisor Hypomineralization
Enamel formation can be divided into 3 main stages... what are they?1. Matrix formation, 2. Mineralization & 3. Maturation
Hutchinson’s incisors and Mulberry Molars are associated with congenital contraction of what disease?Syphilis
Enamel Hypoplasia premolar defects associated with periapical infections in the primary molarsTurner's Tooth
Amelogenesis imperfecta that is pitted, with linear depressions, or that look like crown preps would be _____ type Amelogenesis ImperfectaHypoPLASTIC
AMelogenesis imperfecta where the teeth have a normal shape but have an opaque white-brown mottled appearance and is difficult to distinguish from dentin on radiograph is _____ type Amelogenesis ImperfectaHypoMATURATION
enlargement of the pulp chamber extending apically is called ______Taurodontism
Thistle-shaped pulp chamber associated with what type dentinal dysplasiaType 2 dentinal displasia (coronal dentin dysplasia)
peri-apical disease, short roots and crescent shaped pulp chamber associated what type dentinal dysplasia?Type 1 dentinal dysplasia (radicular dentin dysplasia)
Dentin Dyplasia Type 1 subtype with pulp stones in coronal portion of pulp canal1d
condition where most teeth show crescent shaped pulp chamber remnants and roots are short (tendency for PARL's)Dentin Dysplasia Type 1
condition where root length is normal but pulp chamber is thistle tube shaped and pulp stones may be present in pulp chambersDentin Dysplasia Type 2
condition (aka ghost teeth) that affects a focal area of the dentition with thin enamel and dentin surround large pulpRegional Odontodyspluasia
Does Regional Odontodysplasia have a hereditary cause?No, and we don't really know what causes it
condition where Invagination of the crown or root that is lined by enamelDens Invaginatus
Dens Invaginatus Type that is confined to crownType 1
Dens Invaginatus Type that extends below CEJ level (may or may not communicate with pulp)Type 2
Dens Invaginatus Type that extends through root and perforates in the apical or lateral radicular areaType 3
What teeth are most likely to have Coronal Dens Invaginatus?Maxillary Incisors (esp laterals)
condition where Tear-drop or hour glass opaque line seen within the pulp chamber, often associated with asymptomatic PARLDens Invaginatus
most common microdontia that is inherited traitPeg-Lateral microdontia
term for teeth that are smaller than normalMicrodontia
3 systemic conditions associated with generalized microdontiaHypopituitarism, Congenital Heart Disease, Down's Syndrome
aborted attempt of toothed to divide, crown looks wider, but normal root morphologyGemination
Two teeth that are connected by dentin unionFusion
Two teeth that are connected by cementum unionConcrescence
Tooth number normal but one tooth is notched and widened this is ____gemination
Concrescence is most commonly observed in what region?Maxillary molars
condition where teeth are larger than normalMacrodontia
Macrodontia most commonly occurs in what type of teeth?Incisors and Canines
term for abnormal angulation or bend in the root or crown of a formed toothDilaceration
Small masses of enamel found near furcation or CEJEnamel Pearl
Lack of development of 6 or more teethOligodontia
Lack of development of 1-5 teethHypodontia
condition with an extra incisor located in the midlineMesiodens
Most common supernumerary toothMesiodens between max centrals
Second most common supernumeraryMax 4th Molar
