questions and answers 2026\2027 A+ Grade
MRSA
- correct answer Methicillin-resistant Staphylococcus aureus-is a strain of the staph bacteria that lives on
20-30% of the population but does not cause infection in all who are colonized with it. MRSA resides on
the skin and in the nasal passage, and once you contract a MRSA staph infection it can be very difficult
to eradicate the bacteria.
MRSA antibiotics
- correct answer Many antibiotics can be used to treat this condition. Look for any of these: vancomycin,
linezolid, bactrim, septra, tetracycline, minocycline, doxycycline, and clindamycin.
Prednisone
- correct answer Delayed wound healing, poor healing, with increased risk of infection. This medication
affects the immune response.
Ultrasonic insert with plastic tips
- correct answer Can be used with implants for removal of calculus. Also, titanium and plastic hand
instruments can be used on implants.
Oraqix duration
- correct answer Approximately 20 minutes.
Hutchinson's Incisors
- correct answer Congenital syphillus- notched incisal edges on incisors, also mulberry molars- tiny
globules of enamel instead of cusps on first molars.
Class I Occlusion
- correct answer (Mesognathic)-normal; mesiobuccal cusp of the maxillary first molar is positioned in the
buccal groove of the mandibular first molar. Maxillary canine occluded with the distal half of the
mandibular canine and the mesial half of the mandibular first premolar.
, Class II Occlusion
- correct answer (Retrognathic) buccal groove of the mandibular first permanent molar is distal go the
mesiobuccal cusp of the maxillary first permanent molar by at least the width of a premolar. Distal
portion of the maxillary canine is mesial to the mesial portion of the mandibular canine by at lease the
width of a premolar.
Division I-retruded mandible with one or more maxillary anterior teeth protruded facially.
Division II- retruded mandible with one or more maxillary anterior teeth inclined lingually.
Class III Occlusion
- correct answer (Prognathic) Buccal groove of the mandibular first permanent molar is mesial to the
mesiobuccal cusp of the maxillary first permanent molar by at lease the width of a premolar. Mesial
portion of the maxillary canine is distal to the distal surface of the mandibular canine by the width of a
premolar.
Leeway space
- correct answer This difference in size, mesiodistally between the two types of teeth. The contour of
the bone covering the narrower roots of the premolars, in addition to the state of flux of the bone
formation in this area, furnishes adjustment for dental arch measurements, making the middle segment
of the arches important architecturally. Leeway space allows the future forward movement of the
permanent molars.
Hairy tongue
- correct answer Elongation of filiform papillae (dorsum) clean tongue.
Hairy leukoplakia
- correct answer Lateral border, white, corrugated lesions, associated with HIV, Epstein Barr virus.
Geographic tongue
- correct answer Benign, inflammatory condition, irregular patches look like map.
