the malocclusion: d. All of the above, depending on the age of the client and the severity of the malocclusion
9. A malocclusion may occur in any of three planes of space. A posterior crossbite is a malocclusion
occurring in which of the following?
a. Transverse plane
b. Vertical plane
c. Superior-inferior plane
d. Anteroposterior plane: a. Transverse plane
10.Two principles important to growth modification therapy are which of the following?
a. Growth modification can be completed in clients of any age, and traditional orthodontic treatment after its
completion will be less involved.
b. Growth modification must be initiated after growth is completed to fully control the outcome of the case, and
it must be conducted only in clients willing to attend more numerous orthodontic appointments than required for
traditional orthodontic therapy.
c. Growth modification must be completed in children at a very young age to correct skeletal discrepancies
before they occur,and plaque control is even more critical during growth modification than in traditional
orthodontics.
d. Growth modification must be carried out in clients who are actively growing, and it must continue until skeletal
growth is complete.: d. Growth modification must be carried out in clients who are actively growing, and it must
continue until skeletal growth is complete.
11.Mild crowding of the permanent mandibular incisors may resolve after the age of 10 for which of the
following reasons?
a. The permanent mandibular incisors are only slightly larger in size than the primary mandibular incisors.
Normal growth of the anterior region of the mandible provides more than adequate room for the permanent
incisors by the age of 12.
b. The presence of primate space distal to the mandibular canines allows space for the mandibular canines to
move distally, creating more room for the mandibular incisors and alleviating mild crowding problems.
c. The tongue will force the permanent incisors facially, creating adequate room to resolve any problems of
crowding.
d. It is not possible for even mild crowding of the permanent mandibular anterior teeth to resolve at this time
because adequate growth of the anterior region of the mandible has not occurred.: b. The presence of primate space
distal to the mandibular canines allows space for the mandibular canines to move

and possibility of relapse.
True
False: False
13.Function, esthetics, dental disease aversion, trauma prevention, and pos- sible perio improvement are just a
few of the aims and benefits of orthodontic treatment.
True False:
True
14.Which of the following are considered DISADVANTAGES to having ortho- dontic treatment?
discomfort dietary
changes timely

15.There is always a little bit of root resorption with orthodontic treatment, but it is usually insignificant.
True False:
True
16. The risk factors for apical root resportion during orthodontic treatment are: blunt roots, pipette-shaped
roots, previous trauma, nail biting, and treatment factors such as prolonged tx, high forces and certain orthodontic
movements. True
False: True
17.Endodontics will always be needed in previously traumatized teeth be- cause the trauma produces
degenerative changes in the pulp that decreases it's ability to cope with orthodontic treatment.
True
False: False
18.The biomechanic factor of tissue response refers to:

b. most favourable response of every tooth to a force applied to it
c. a continuous, steady force of optimal degree applied to a tooth which will yield the most effective and
physiologic tooth movement
