PEDD Final Fall 2018
Terms in this set (51)
Congenitally missing primary tooth, usually have
a congenitally missing permanent tooth
• __________ replaces when tooth lost prior to permanent first molar erupts
band and loop:
uni or bilateral which can be used if permanent incisors aren't present
Is the appliance of choice when the primary second molar is lost before the eruption of the permanent molar
partial denture space maintainers
- Useful for bilateral posterior space maintenance when more than one tooth has been lost
- Delayed permanent incisors - esthetics
- Indicated for space maintenance when multiple primary posterior teeth are missing and permanent incisors have erupted
- Does not contact the primary molars or premolars
- May incorporate adjustment loops mesial to molar bands so that it can be periodically adjusted and activated
TPA (transpalatal bar)
- Maxillary fixed or removable appliance that extends from one first molar along the contour of the palate to the first molar on the opposite side.
- Can be use as an space maintainer, for molar de-rotation, root movement and expansion
Nance Holding arch
- Consist of a heavy palatal wire soldered to the palatal aspect of the first molars
- The wire is directed anteriorly and is attached to an acrylic button that rest against the most superior and anterior aspect of the palatal vault
- Use for space maintainer and anchorage reinforcement
Cleft lip/palate classifications
I: soft palate only
II: hard and soft palate
III: complete unilateral of soft palate hard palate, lip, and alveolar ridge
IV: bilateral complete
Hypodontia, dental hypoplasia, sparse hair, hypohydrosis/anhidrosis, asteatosis, deficient salivary flow, protuberant lips, saddle nose, dry/scaly skin, fissured mouth corners
• Dentiongenesis imperfecta - x-rays look like?
no pulp,very small pulp
What age group virus associated with acute herpetic gingivostomatitis?
6months- 5yrs old
• Gagging child - which impression first
secure lower (mandibular)
• Impacted canine -
get an ortho consult!
Large ANB angle / mandibular retrusion (Severe Class II) usually require
most important to calculate dosage of local anesthetic
• Asthma pts -
have them bring their inhaler to their dental appointment
• NEVER use opiates on
most common cranial malformation
Cleft lip /palate -
Discolored primary tooth / symptom free / no radiographic changes- _________ treatment
Serial extraction usually malocclusion
crowded Class I
Pseudo-Class III vs. real Class III -
pseudo usually has a forward shift of mandible during closure
Know what Primary Herpetic Gingivostomatitis looks like clinically (photograph)!
- union of cementum of two teeth
Always allow _______________ to re-erupt if opportunity exists
anterior primary incisor
• 88% re-erupt within 6 months
totally avulsed primary tooth (possible ankylosis
Congenital absence of teeth from-
interruption in Initiation Phase
Dental development proceeds at a rate independent of
skeletal development & independent of R & L sides of mouth.
Dental age => refers to
dental maturation not chronological.
Ectodermal cells role in tooth development
(shape of crown and root).
Enamel dysplasia affects perm laterals at ________ of age.
-4 year old => missing both mandibular 1st molars /no primate spaces => what?
band and loops
Growth of cranial base precedes
the growth of jaws
Bite wings or pan of a child - 6 years of age may not show evidence of
mandibular second premolars => develop later.
Permanent teeth emerge clinically => ______ root structure developed
Anterior mandibular perm teeth before eruption are ___________________ to the primary teeth.
inferior & lingual
amelogenesis imperfecta vs. dentinogensis imprefecta
• Affects both dentitions usually
• How distinguish from other enamel defects:
• Confined to distinct patterns of inheritance
• Often associated with anterior open bite (60% of cases)
• 4 major categories - described in stage of tooth development in which if occurs
• Type I hypoplastic
• Type 2 hypomaturation
• Type 3 hypocalcified
• Type 4 hypomaturation, hypoplastic with taurodontism
dentinogensis imprefecta :
• Defect: histodifferentiation
• Defectindentinmatrixamorphic,disorganized, atubular, circumpulpal dentin
• Mantle dentin normal
• Opalescent teeth in both dentitions
• 3 Basic Types
• Shields Type I • Shields Type 2 • Shields Type 3
Know signs, symptoms, and age group of Primary Herpetic Gingivostomatitis
When to correct crossbite
immediately without waiting for the eruption of permanent first molars
Untreated unilateral cleft lip and palate patients frequently have
a posterior crossbite.
Class I Cleft Palate involves
Condylar growth => _______ growth
Class II cleft palate =>
soft and hard palate
Bone tissue grows by =>
appositional growth and differentiation of cartilaginous tissue.
Cartilage differs from bone in that cartilage increases in size by =>
__________ are not used to calculate the dosage of a drug for a child
Absence of pulp chambers =>
Spacing between primary teeth => better chance
large permanent teeth can be accommodated
Chief causes of anterior crossbite =>
usually over-retention of maxillary deciduous incisior
Anterior crossbite in primary dentition usually indicative of
skeletal growth problems.
Supervision of child's development of occlusion most critical between ______ years of age
