FAGD Exam ____________ seem to decrease periradicular inflammation caused by extrusion of root canal filling materials - Dexamethasone (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 tim e. - Both T (T/F) Dispersion strengthening increases the capability of blocking a crack from propagating through the ceramic material. Dispersion strengthening of ceramic increases when the crystal content of leucite increases. - both true (T/F) Following administration of an inferior alveolar nerve block (IANB), the clinician should routinely administer a buccal nerve block. The buccal nerve provides sensory innervation to the buccal soft tissues adjacent to the mandibular molars only. - 1 FALSE 2 TRUE (T/F) Geriatric patients have more periodontal disease and gingival recession than the younger patients. The connective tissue layer of the oral mucosa in geriatric patients becomes thinner and loses elasticity, decreasing the mucosa's ability to act as a barrier. - both true (T/F) In distal extension partial dentures, support from the residual ridge becomes more important as the distance from the last abutment decreases. Several factors influence the support a partial receives from the ridge, one of which is the occlusal conta ct with the opposing arch. - both FALSE (T/F) In fabricating a temporary crown for a tooth prepared for full coverage, the temporary crown should be overextended gingivally. The primary function of the temporary crown is to protect the gingival margins. - Both are False (T/F) Infants (less than 5 years old) with active TB receiving chemotherapy can be treated as an outpatient. - True (T/F) Internal resorption is more common than external resorption. Internal resorption takes place when there is a vital pulp - 1 F 2 T (T/F) Patients suffering from an angina episode usually report sharp stabbing pains to the midchest region. A patient who has stable angina is considered a high cardiac risk patient - Both FALSE (T/F) Roughening the post surface will improve retention of the post - True (T/F) Under clinical conditions, composite resins can suffer surface wear and degradation by coming in contact with oral fluids. Nanofilled composites wear significantly more than natural human enamel in a 3 and 5 year study. - 1 T 2 F (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 imm ediate 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. - 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 prematu re 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. - Both T 1 wall - osseous defect - tx: resective curretage hemiseptal 2 walled osseous defect - most common crater 3 phases of GI setting - ion leaching phase setting reaction polysalt -gel phase 3 walled osseous defect - reconstruction with grafting 4 Components for Negligence - -duty to render care must be shown -breach of duty occurred -patient suffered damages -damages suffered must be proximately caused by breach of that duty A hue - orange red A panoramic radiograph of a 15 -year -old boy reveals an asymptomatic radiolucency between 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 - traumatic bone cyst. A panoramic radiograph shows several areas of well -defined bone destruction lacking any cortical boundary. The lesions are multiple, separate, and appear to be "punched out." These radiographic changes are consistent with - multiple myeloma A patient presents for emergency treatment of pain associated with the permanent mandibular 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 promote prolonged painful responses for at least a minute following removal of the stimulus. The diagnosis is consistent with: - irreversible pulpitis A patient presents minutes after a maxillary permanent central incision has been traumatized but not fractured. The crown is displaced facially. The tooth cannot be repositioned properly with digital pressure. The best course of action would be: - reposition the tooth with forceps and splint for several weeks A patient presents with acute diffuse cellulitis and trismus due to pulpal necrosis of the mandibular second molar. The most appropriate technique for achieving regional anesthesia is - Vazirani -
