What keeps restorations in place?
Friction (and some bonding)
Internal resorption often happens with reaction of __ used in ___ in primary teeth
Materials and methods
(Don't use TempX (it has calcium hydroxide base which is linked to internal resorption)
What is cellulitis caused by?
Primary or permanent pulpal necrosis
What tooth is celllitis most often involved with?
First primary molar
The symptoms of an acute alveolar abscess can be relived by ___, however the main tenet of treatment involves...
Removal of the cause of infection, namely, the necrotic pulp tissue. Drainage should be established through pulp chamber or extraction. Extraction is best choice for emergencies.

What makes up over 50% of all childhood cancers
ALL is most common type
brain tumors are most common solid type (gliomas, medulloblastomas)
What are the differences between compound and complex odontomas?
Compound - "denticles" most frequent in anterior region of maxilla w/ canine. Asymptomatic.
Complex - no resemblance of normal tooth. Occurs in posterior region of mandible. Associated with missing teeth
How are odontomas treated?
Simple local excision
When is the critical time that hypoplasia caused by fluorosis can occur?
Between birth to ages 4-5.
Oligodontia is missing more than __ teeth
What is the difference between type 1 and type 2 dentin dysplasia?
Type 1 - no pulp chambers and canal
Type 2 - thistle shaped pulp chamber/canal
What are the most commonly missing teeth in ectodermal dysplasia?
Mandibular incisors and premolars
How is erythroblastosis fetalis associated with discolored teeth?
