Dental Anatomy EFDA Exam
Questions and Answers 100% Pass
Dental Morphology - ✔✔The study of the structure and form of the teeth
Bud Stage - ✔✔1st stage of odontogenesis (origin of the tooth)
Bud stage - ✔✔Initiation begins when tooth begins formation from the dental lamina
(begins in utero appr. 13-16 weeks
Bud Stage - ✔✔Epithelium thickens
-U shape
-eventually 20 localized thickenings correspond to future primary dentition
Bud Stage - ✔✔Successional lamina
-forms lingual
-permanent teeth
-slower growth
Cap Stage - ✔✔Bud of tooth grows and changes shape
Cap Stage - ✔✔Proliferation
-Ectoderm (crown, skin, hair, nails)

, Cap Stage - ✔✔Forms the dental sac
Cap Stage - ✔✔Matures dentin, cementum and pulp of tooth
Bell Stage - ✔✔Histodifferation takes place
-Specialization of cells
Bell Stage - ✔✔Ameloblasts- Enamel forming cells
Dentoblasts- Forms Dentin
Cementoblasts- Forms cementum
Apposition - ✔✔Maturation stage
Odontogenesis reaches completion
Enamel, Dentin & Cementum are formed in layers and fuse together in the appropriate
manner
Apposition - ✔✔Calcification occurs
-last development stage prior to eruption
Enamel Dysplasia - ✔✔Disturbance of apposition
- opaque spots
-rough enamel
- weakened tooth structure
Eruption - ✔✔Movement of teeth as it emerges through surrounding tissue
Attrition - ✔✔Wearing away of the life cycle of the tooth on the incisal or ccclusal
surfaces during eruption
Clinical crown - ✔✔That part seen above the gingiva
