when treating a hypertensive patient, one of the following is not correct:
stress level should be minimized
adrenaline in local anaesthesia is contraindicated sudden severe increase in blood pressure may result in cardiac arrest
some anti-hypertensive drugs cause postural hypotension, thus the patient should be
raised from supine to upright position slowly none of the above
S. mutans and S. sangius are mostly incriminated for nfective endocarditis of dentalorigin because:
they are present in large numbers in the mouth
they are released into the blood stream in large numbers during inferior alveolar
bloc!s they have comple" attachment mechanisms enabling them to adhere to haemoglobin
in the #$Cs
the first and third answers
all of the above
patients at ris! from infective endocarditis re%uiring antibiotic prophyla"i" includethe following:
recent myocardial infarction of less than & months
coronary arteries bypass graft history of childhood rheumatic fever
cardiac implanted pacema!er
all of the above
for the prophyla"is of bacterial endocarditis:
amo"ycillin 'g of a single oral dose can be given (ust before the operation for patients with a history of endocarditis gentamycin and amo"ycillin are given warfarin has to be given
the first two answers
all of the above
patients with angina pectoris attending for e"traction of a lower molar tooth:
re%uire adrenaline ) mg * prior to the e"traction
are at higher ris! of developing udwigs angina are at higher ris! of myocardial infarction than patients with haemophilia
all of the above
none of the above
the management of myocardial infarction in the dental clinic includes:
laying the patient flat on a firm surface give warfarin orally
give o"ygen
all of the above

ndications for surgical removal of a tooth or roots include:

$. n!ylosed roots / hypercemented rootsC. 0eeth with apices at right to long a"is of the teeth
1. $ /C
2. ll of the above
*ucoperiosteal flaps used in oral surgical procedures are raised:
. 0o allows surgical access to underlying tissues.$. 0o maintain blood supply to ad(acent mucosa
C. 0o prevent postoperative infection
1. $ /C
2. ll of the above
3rinciples of flap design include:
. 4ince soft tissues heal long the length of the incision, smaller incisions heal faster
than longer incisions.$. 5ull-thic!ness mucoperiosteal flap provide poor access to impacted tooth6root and
should be avoidedC. 0he incision should be designed so that after bone is removed the suture line lies
upon, and is supported by the blood clot of the bony defect created by surgery.
1. / C2. 7one of the above
1uring and after surgical e"traction bone is removed in order to:
. #educe size of bony soc!et$. 3rovide a space into which the tooth6root may be displaced
C. #emove sharp edges and bony pro(ection
1. / $2. ll of the above
0echni%ues used for bone removal during surgical e"traction:. Creating a gutter in the bone alongside the crown of the tooth.
$. 3ostage-stamp method using a small round bur.
C. 8sing a chisel to remove bone

Cardiopulmonary resuscitation C3#; is indicated when:
the heart stops pumping a bolus of food has suddenly bloc!ed the oropharyn"
angina becoming unstable in a chronic smo!er male
none of the above
bsence of arterial pulse occurs after arrest of the heart muscle, this is confirmed by:
very low systolic blood pressure and a high diastolic pressure
very low systolic and diastolic blood pressure
wheezy breath followed by convulsions the second and third answers
none of the above
& year old male with a history of a coronary arteries bypass graft years ago
presenting for the removal of a grossly carious lower right first molar. @hich of thefollowing is correct with regard to his dental managementA
his 7# must be chec!ed pre-operatively if he is ta!ing warfarin
there is no need for antibiotic prophyla"is
oral 0emazepam may be given to reduce an"iety the second and third answers
all of the above
the commonest cause of collapse fainting; in the dental surgery is:
myocardial infarction
adrenal insufficiency vasovagal syncope
4tro!e
all of the above
5or an intra-oral surgical procedure, releasing incision of the flap should be
designed to be sited away fromA

during the removal of a buccally displaced upper third molar, the ape" of the palatal
root has fractured. 0his can be left in situ providing that:
it is less than = mm in length the tooth in not infected
the ma"illary sinus is not infected
the first two answers all of the above
hypercementosis of teeth roots: is an important cause of toot fracture during e"traction
in upper premolars, e"traction may cause oro-antral communication
is a feature of $ehcets disease
the first and second answerall of the above
while raising a flap to remove a retained root of an upper second premolar:
the flap must not e"ceed the alveolus around the root to reduce postoperative pain the middle superior alveolar nerve must be identified and protected
three sided flaps are favorable to envelope flaps to prevent gingival recession all of the above
none of the above
the transalveolar e"traction of the remaining roots of the lower right second
premolar may carry the following ris!s:
numbness of the right side of the chin area
bleeding from a branch of the lingual artery damage to the left mandibular condyle
all of the above
none of the above
a chisel and hammer can be used to remove bone for transalveolar e"traction
according to the following: a stop cut should be placed to prevent fracturing the (aw along its bone grains
this techni%ue is mainly used for the conscious patient to measure the needed force
according to the patients response
does not re%uire saline coolant but the chisel should be stored in a sterile ice bath all of the above
none of the above
the removal of upper third molars:
should never be attempted with curved elevators
may result in fractured coronoid process may result in fractured ma"illary tuberosity

caries affecting it or its neighboring teeth for orthodontic reasons
the second and third answers
all of the above
which of the following is considered an impacted tooth:
a partially erupted lower 'rdmolar in a vertical position in a B) year old female whohas enough space distal to the Bndmolar
a completely unerupted lower 'rdmolar in a vertical position in a =B year old male
who has enough space distal to the Bndmolar
a partially developed, totally unerupted lower 'rdmolar that is tilted mesially in a )=year old male
all of the above
none of the above
which of the following is classified as C-B according to $ell and 9regory system:
a lower wisdom tooth that has its highest aspect between the occlusal plane andcervical line of the second molar with half of the crown within the ramus
a lower wisdom tooth that has its highest aspect below the cervical line of the
second molar with half of the crown within the ramus a lower wisdom tooth that has its highest aspect below the cervical line of the
second molar with all of the crown within the ramus
a lower wisdom tooth that has its highest aspect in level with the occlusal plane of
the second molar with hlaf of the crown within the ramusC> a lower wisdom tooth that has its highest aspect between the occlusal plane and
cervical line of the second molar with all of the crown anterior to the ramus
a transverse impaction of the lower ' rdmolar is a severe form of mesioangular
impaction:
true false
which of the following is notan indication for the e"traction of an impacted lower
'rdmolar: gross caries of the 'rdmolar with crowding in the lower anterior teeth in a patient
who is not willing to have orthodontic treatment

e"traction of an impacted, fully covered 'rdmolar that is not associated
radiographically with any pathology for the treatment of une"plained facial pain:
will definitely cure the patient definitely will not cure the patient
is controversial because it may or may not cure the patient
should be considered a routine practice is contraindicated
