the mandibular second premolar and first molar, unilaterally. The margin of the lesion is well
defined and extends superiorly between the roots of the teeth. There is no buccal expansion; all
teeth are vital and noncarious. The radiographic findings are most consistent with a/n -

first molar. There is a history of pain when drinking cold liquids. Mesial and distal caries appear
radiographically to extend through the dentino-enamel junction. Heat and cold stimuli both

When seating enamel bonded restorations, if the etched enamel becomes contaminated with
saliva, how should it be treated - Answers Re-etch enamel for 15 seconds, rinse, dry, then apply
bonding agent.
When teeth overerupt, they bring the bone and gingiva with them. This is termed _____________. -

The average incisal display of the maxillary central incisors of 20-year-old females in repose
is__________ mm. - Answers 3-4
The average upper lip length for a young female is __ mm - Answers 20-22
(T/F) When a dental implant is placed at the same time as an extraction (immediate implant),
the bone remodeling process does not take place in which the bone resorbs from the facial to
the lingual, often resulting in compromised bone dimensions. If no immediate implant or bone
grafting is completed at the time of extraction, resorption has been shown to result in
approximately 1 to 2 mm of vertical bone height and 4 to 5 mm of horizontal bone width within
1 to 3 years. - Answers Both T
The anterior maxilla has a bone classification of _______. - Answers D3
To minimize operative trauma to the implant surgical site in D3 bone, the final phase of site
preparation should be prepared with a/an - Answers ultra slow-handpiece, high torque (15-30
rpm)
With immediate implant placement, the implant-bone interface is weakest and at most risk of
overload at 3 to 6 weeks after surgical insertion. At 4 months the bone is still only _____ %
mineralized, organized lamellar bone. - Answers 60
(T/F) An important complication to prevent after implant surgery is infection. To reduce
infection the clinician should prescribe an appropriate antibiotic, a .12% chlorhexidine gluconate
rinse, utilize aseptic surgical technique, and minimize surgical time. - Answers Both T
(T/F) When comparing nonresorbable vs resorbable guided bone regeneration (GBR)
, membranes, a disadvantage of nonresorbable membranes includes the need for reentry
procedures for membrane removal and frequent postoperative infections that may follow
premature membrane exposure. In order to overcome these limitations, resorbable membranes
have become a popular alternative because they are biodegradable and are less likely to
become infected even in the event of exposure. - Answers Both T
