HOTTEL BOOK EFDA EXAM
QUESTIONS AND ANSWERS
How many types of composite resin are there? -
correct answer ✅There are 5 types of resin divided into categories
based on size, amount and composition of inorganic fillers
Conventional Large particle composite resin -
correct answer ✅Contains 75%-80% inorganic filler by
weight(sturdevant). The particle size is large compared to the other
four resin types. Due to the larger size and extreme hardness of the
filler particles, conventional composite has a rough surface texture
What type of staining is Conventional Large Particle resin
susceptible to? -
correct answer ✅Extrinsic
ex. Coffee, hot chocolates smoking
Micro - filled resins -
correct answer ✅Polishsable composites, were designed to
improve the rough surface characteristics of conventional larger
filler particles with a surface that closely resembles tooth enamel.
Micro- filled resins have very tiny (submicron, 0.04 microns) sized
particles of colloidal silica.

QUESTIONS AND ANSWERS
What are Micro - filled resins less susceptible to? -
correct answer ✅Recurrent caries, plaque build up, or extrinsic
staining
What is the inorganic filler context of Micro -
filled resins -
correct answer ✅40%-60%
What are micro- filled resins more susceptible to than conventional
composite resins? -
correct answer ✅Shear fracture, however, they display greater
wear resistance to toothbrush abrasion. Uncommonly used for
posterior teeth.
Hybrid composite resins -
correct answer ✅Contain submicron sized particles inter-dispersed
with the larger particles allowing a smooth surface texture to be
attained in the finish restoration
Why were Hybrid composite resins created? -
correct answer ✅To combine the good physical properties of
, HOTTEL BOOK EFDA EXAM
QUESTIONS AND ANSWERS
conventional composites with smooth surface typical of
microfilmed resins.
What is the inorganic filler context of hybrid composite resins? -
correct answer ✅70%-80%
What physical properties of hybrid composite resins are better than
Conventional composite -
correct answer ✅Smoother
Micro filled hybrids composite resins -
correct answer ✅Contains a mix of particle sized and have been
the most popular systems because they combine the properties of
micro fills with the hybrids to create a more polishable and strong
result.
What do Micro hybrids composite resins offer? -
correct answer ✅Different light opacities to stimulate the color
vitality of natural teeth - allows the duplication of colors of natural
tooth structure.
