quadrant dentistry

Question 1

quadrant

Answer 1

dividing the jaws into 4 parts from midline of each arch to the most distal tooth

Question 2

sextant

Answer 2

deviding into 6 parts (Anterior is canine to canine, left or right is 1st premolar back)

Question 3

quadrant dentistry

Answer 3

treated all affected teeth in 1 quadrant/sextand dring the same vist
regardless of material/technique used

Question 4

why do quadrant dentistry

Answer 4

aid in 4 handed and when using a EFDA

good for efficiency and productivity

Question 5

advantage of quadrant dent to patient

Answer 5

less # of appointments (save time and expense
Less discomfort (less injections)

Question 6

advantage of quadrant dent to dentist

Answer 6

more effieicny
more productivty
single anesthtetic
single rubber dam
same rotary/hand instrumnets used

Question 7

considerations for quadrant dentistry

Answer 7

more chairside time (adjust time and schedule as needed)

Question 8

sequence for quadrant dentsitry

Answer 8

follow the ideal treatment sequence

emergency, eliminate active disease, final prosthesis

Question 9

indications for quadrant dentistry

Answer 9

adjacent interproximal caries (kissing cavities)
multiple faulty restorations: open leaking margins, open proximal contact, gingival overhands, severe marginal breakdown, recurrent caries
pediatric
medically compromised patients (severe CHF, mental disability)

Question 10

contraindications for quadrant dentistry

Answer 10

lack of dentist experience
patient with TMJ dysfucnction
patient who cannot stay reclined

Question 11

copper in low copper amalgam

Answer 11

<5%

Question 12

what is made in low copper amalgam reaction

Answer 12

gamma 2

Question 13

problem with gamma 2 phase

Answer 13

weakest
most corrosion (pitted and marginal fracture
High creep

Question 14

high copper amalgam

Answer 14

greater than 6% copper

Question 15

gamma

Answer 15

Ag3Sn

Question 16

gamma 1

Answer 16

Ag2Hg3

Question 17

gamma 2

Answer 17

Sn7-8Hg

Question 18

benifit of high copper amalgam

Answer 18

has enough Cu to eliminate gamma 2 phase formation and instead forms n prime(secondary reaction

Question 19

n prime phase

Answer 19

Cu6Sn5

Question 20

n prime phase verese gamm 2 phase

Answer 20

n prime is stronger and more corrosion resistant, les pitting
prevents sliding of gamma 1 so less creep and marginal breakdown

Question 21

pro and con of lathe cut amalgam

Answer 21

pro: high condenstaion force needed so tight contact
con: high surface area, more Hg and more expansion

Question 22

pro and con of spherical cut amalgam

Answer 22

pro: pack effeciently and slide easily (less voids and high strength)
con: difficult to achieve proximal contact

Question 23

benifit of conventional dentistry for back to back amalgam

Answer 23

adjacent inract tooth structuer serves as a guide

contact position medio distally maintained

Question 24

what tooth do you do first in back to back amalgam restorations

Answer 24

from most posterior tooth

Question 25

what tooth do you restore first for multiple adjacent class II preps

Answer 25

restore 2 non-adjacent teeth. contra angled tofflemire retainer or automatrix is useful

Question 26

why non band and restore adjacent teeth simultaneously

Answer 26

excessive wedging | high change of open contacts due to 2 bands
