What is parotid papilla?
The facial profile for class I malocclusion.
What is mesognathic?
MB cusp of maxillary first molar(by more than width of premolar) is mesial to MB groove of mandibular first molar and maxillary incisors protrude facially from mandibular incisors; retrognathic profile.
What is Angle Classification Class II Division I?
Pulp chambers and pulp horns are typically larger or smaller on primary teeth then permanent teeth
What is larger?
Intrinsic yellow to yellow-brown discoloration within the teeth due to antibiotic therapy during child's tooth development.
What is tetracycline stain?

What is the uvula?
6 to 10 months is when this primary tooth typically erupts
What is the primary mandibular central incisor?
The space or gap between the arches when the mandible is at rest.
What is the interocclusal clearance or freeway space?
14-18 months is when this primary tooth erupts
What is the maxillary or mandibular first primary molar?
Union of two adjacent tooth germs that result in large tooth with two pulp cavities with one less tooth in dentition commonly affecting anteriorss.
What is Fusion?
Small visible yellowish elevations on the labial and buccal mucosa that represent deeper deposits of sebum from misplaced sebaceous gland tissue.
What is Fordyce granules or spots?
The teeth are attached to the bony surface of the alveoli by a fibrous tissue.

The scallop-shaped line of demarcation between the firmer and pinker attached gingiva and the movable and redder alveolar mucosa that lines the vestibules.
What is the mucogingival junction?
Included in this class of malocclusion is the crowding of teeth and the mesial drift that occurs as the dentition ages.
What is Class I?
The end point of closure of the mandible or the mandible is in the most retruded position it can be in.
What is Centric relation?
The space in a mixed dentition period and phase three of the dental arch development that is due to the difference in size, mesiodistally, between primary molars and permanent premolars.

Etiologic factor for Anodontia.
What is hereditary, endocrine dysfunction, systemic disease, or excess radiation exposure?
A developmental growth of bone covered in oral mucosa that may occur on the mandible and maxilla.
What is torus or tori?
