Oral Health and Dental Conditions Quiz

Lichen Planus

• Lichen planus most commonly occurs on the buccal mucosa.

Zinc-Phosphate Cement Setting

• To retard the setting of zinc-phosphate cement, increase the concentration of water in the liquid.

Tooth Avulsion Transport

• In the absence of "Hanks balanced salt solution", the best media to transport an avulsed tooth is milk.

White Lesion on Retromolar Pad

• The most likely diagnosis for a white lesion on the retromolar pad opposing a non-functional molar is alveolar ridge keratosis.

Osteoporosis, Glaucoma, Hypertension, and Peptic Ulcers in a 65 year old with Crohn’s disease

• The most likely cause of these conditions in a 65 year old with Crohn's disease is malabsorption syndrome.

Edentulous Patient with Tuberosity Interference

• When examining an edentulous patient, if the tuberosities contact the retromolar pads at the correct occlusal vertical dimension, the treatment of choice is to reduce the retromolar pads surgically to provide the necessary clearance.

Missing Teeth and Space Maintainers

• In a 7 year old patient missing tooth 5.5 and 7.5, if space maintainers were not placed, a mixed dentition analysis showing a maxillary space loss of -5mm on the right and -3mm on the left indicates potentially significant space loss.

Remounting of Dentures

• Remounting of processed dentures is done to correct occlusal disharmony caused by errors during the mounting of casts on the articulator.

Extraction of Maxillary Third Molar

• When extracting a maxillary third molar, the tuberosity is fractured and remains attached to the surrounding soft tissue.
• This scenario requires reflecting the mucoperiosteum, removing the tooth, leaving the tuberosity in place, and suturing.

Multilocular Lesions

• Multiple multilocular lesions associated with vital mandibular teeth are present in a patient.
• A histopathologic analysis reveals the presence of multinucleated giant cells.
• The most appropriate management is to initiate endodontic treatments.

Inadequate Ferrule

• An inadequate ferrule can be addressed by performing elective endodontic treatment and a post core to increase tooth structure available for crown preparation.

Radiation Sensitivity

• The tissue most sensitive to radiation is nerve tissue.

Methemoglobinemia

• Methemoglobinemia is a potential complication associated with excessive doses of prilocaine.

Streptococcus Mutans

• The level of Streptococcus mutans is significantly higher in the bacterial plaque adjacent to posterior restorations.

Elevated Serum Alkaline Phosphatase and Hydroxyproline

• Elevated serum alkaline phosphatase and elevated urinary hydroxyproline levels are associated with Paget disease.

Gluteal Intramuscular Injection

• A gluteal intramuscular injection can be safely administered in the lower lateral quadrant.

Drug Metabolism in Elderly

• The metabolic clearance of carbamazepine is not reduced in elderly patients.

Local Anesthetic Technique

• The Gow-Gates block requires the needle to contact the neck of the condyle.

Sickle Cell Anemia

• Sickle cell anemia is a genetic disease.

Biocompatibility Tests

• Biocompatibility tests conducted in vitro predict human cell growth or death.

Free Gingival Graft

• Infiltrating new blood vessels are histologically detectable 2 to 3 weeks following a free gingival graft.

Gingival Recession

• To prevent gingival recession, a full gold crown should have normal contour reproduced.

Periodontal Ligament Space Widening

• Widening of the periodontal ligament space is not seen radiographically in Scleroderma (systemic sclerosis).

Angiotensin II Converting Enzyme

• Angiotensin II converting enzyme is primarily produced in vascular endothelial cells of the lung.

Maximum Contact Between Teeth

• Maximum contact between teeth in chewing occurs in the position of habitual occlusion.

Metronidazole

• Patients prescribed metronidazole should avoid alcohol.

Sterilization of Carious Dentin

• Sterilization of carious dentin without pulp injury is not assured by any of the listed options.

Periodontal Pathogen and Estrogen

• Porphyromonas gingivalis can use the hormone estrogen as a growth factor.

Abscessed Tooth Infection

• If an infection from an abscessed permanent mandibular first molar perforates the lingual cortex, the mylohyoid muscle determines the space to which the infection will spread in the soft tissues.

Bleeding and Swollen Gums

• A 13-year-old patient with red, bleeding, and swollen gums present only on the labial gingiva of the maxillary anterior teeth most likely has mouth breathing habit.

Multiple Cysts of the Jaws

• Gardner syndrome has multiple cysts of the jaws.

Factors Influencing Overdenture Success

• Factors influencing overdenture success include the amount of underlying trabecular bone and faulty lingual eruption of the second premolars.

Hypochromic Anemia

• Hypochromic anemia is associated with iron deficiency.

All-Ceramic Maxillary Anterior Crown Contraindication

• An excessive overjet and overbite are a clinical contraindication for an all-ceramic maxillary anterior crown.

Mercury Hygiene

• A quarterly mercury assessment for office personnel is essential for ensuring acceptable mercury hygiene in a dental office.

Polyalkenoic Cements

• Polyalkenoic cements contain itaconic acid to ensure a clinically acceptable setting time.

Class II Amalgam Restoration in Primary Molars

• A preparation for a Class II amalgam restoration in primary molars should include the margins extended 1mm subgingivally.

Functional Appliance Limitation

• Retroclination is the most limiting factor in the construction of a Class II functional appliance.

Compounds Released by Inflammatory Cells

• Interleukin-1 is a compound released by inflammatory cells that induces bone resorption.

Viral Transmission in Vaccinated Dental Healthcare Workers

• Hepatitis B has the greatest chance of transmission in an occupational exposure to a vaccinated dental healthcare worker.

Ludwig's Angina

• Ludwig's angina can cause death by asphyxia.

Necrotic Pulp

• Chronic periradicular periodontitis results from a necrotic pulp.

Root Canal Obturation Objectives

• The mechanical objectives when preparing the root canal system for obturation with gutta-percha should include development of a continuously tapering cone in the root canal, removal of irregularities, and maintenance of an intact foramen.

Radiographic Appearance Suggestive of Paget's Disease

• A radiograph displaying a “cotton-wool” appearance and generalized hypercementosis is suggestive of Paget’s disease.

Centric Relation Record

• Assuming a maxillary cast is accurately mounted on an articulator, a centric relation record is used to mount the mandibular cast.

Cold-Cure Acrylic Resins Compared to Heat-Cured

• Cold-cure acrylic resins are less hard and more color stable compared to heat-cured acrylic resins

Continued Smoking and Wound Healing

• Continued smoking impairs wound healing following a surgical procedure because of stain development.
