Primary
What spaces are mainly involved as the primate spaces located within the primary dentition?
What is between primary maxillary lateral incisor and canine
Where is the temporomandibular joint palpated upon examination of the structure?
Just anterior to each ear
When the teeth normally occlude in centric occlusion, the maxillary arch horizontally overlaps the mandibular arch to a condition referred to as
overjet.
What completely encloses the temporomandibular joint?
Joint capsule
Overbite is measured in millimeters with the
periodontal probe.

What is 20
During what weeks of prenatal development does the temporomandibular joint develop?
Eleventh to twelfth week
Lateral deviation of the mandible, or lateral excursion, is evaluated by shifting the lower jaw
side to side.
What bones of the head are involved in the articulation of the temporomandibular joint?
Temporal bone and mandible
Which primary molars usually has a cusp of Carabelli present on its occlusal surface?
Primary maxillary second molar
When does mineralization of the primary dentition begin during prenatal development?
What is during the thirteenth to sixteenth week
What is the depression on the inferior aspect of the temporal bone that is part of the temporomandibular joint?
Articular fossa
Open contacts allow for areas of food impaction from opposing cusps called _____ cusps, which can result in trauma to the interdental gingiva.
plunging
Which primary molar has an H-shaped groove pattern on its occlusal surface?
Primary maxillary first molar
What is the end point of closure of the mandible?
Centric relation
How long does the primary dentition generally function in esthetics, mastication, and speech for a child?
What is from 5 to 12 years
What is not the usual movement of the temporomandibular joint involving the mandible and allowed by the gliding and rotation of the joint?
Subluxation
What is considered the voluntary position of the dentition that allows the maximum contact when the teeth occlude?
Centric occlusion
Which type of bite is characterized by having anterior teeth that do not occlude?
Open bite
How does the primary mandibular canine compare to its permanent counterpart?
Lingual surface is smoother
What must be suspected in a primary or mixed dentition if there is severe periodontal inflammation and destruction with evidence of little dental biofilm?
What is aggressive periodontitis
The muscles that are palpated as part of a complete temporomandibular joint examination include the masseter, temporalis, medial pterygoid, lateral pterygoid, and
sternocleidomastoid muscle.
Which teeth of both arches should be in contact during protrusive occlusion within the permanent dentition?
Central and lateral incisors
What is the estimated percentage of children and teenagers that show some degree of malocclusion?
80%
What is the thick substance that fills the temporomandibular joint, lubricates it, and provides nutrition to parts of the joint disc?
Synovial fluid
