it includes the procedures done for prevention before the manifestation of any signs and symptoms of disease

(a)  

Procedures undertakes after signs and symptoms of disease have appeared in order to prevent the disease from developing into a more serious or full extent.

(a)  

Preservation of the vitality and periodontal support of the remaining tooth structure is obtained by preventive and interceptive procedures

(a)  

procedures done to restore form function, phonetics and aesthetics

(a)  

after the restoration is done, it must be maintained for providing service for longer duration.

(a)  

Enumerate the Purposes of Operative Dentistry: (Answer separating each answers with "-") (Example: Answer1-Answer2)

(a)  

- Covers the anatomical crown of teeth

- Formed by ameloblasts from ectoderm

- Hardest substance in the human body

(a)  

(a)   is defined as the science and art of dentistry which deals with diagnosis, treatment and prognosis of defects of the teeth which do not require full coverage restorations for correction.

Indications for Operative Dentistry (Answer separating each answers with "-") (Example: Answer1-Answer2)

(a)  

groups of enamel rods that intertwine with another group forming a curving irregular path towards the tooth surface.

(a)  

hypomineralized structures of enamel rods and interrod substances that project between adjacent groups enamel rods from the DEJ. They arise from the dentin and extend into the enamel in the direction of the long axis of the crown

(a)  

thin, leaf-like faults between enamel rod groups extending from the enamel surface toward the DE), sometimes extending into the dentin. Contains mostly organic materials

It may serve as pain receptors explaining enamel sensitivity experienced during tooth prep.

(a)  

- the junction or interface of enamel and dentin 

- It is a hypermineralized zone

(a)  

- Formed from the dental papilla of the tooth bud by odontoblasts

- Forms the largest portion of the tooth structure

- Covered by enamel on the crown and cementum on the root

- Forms the wall of the pulp cavity

- Forms throughout life

(a)  

Dentin: Tensile strength ____ Mpa, Compressive strength ___ Mpa,

(a)  

forms the initial shape of the tooth; usually completed 3 years after tooth eruption (permanent teeth)

(a)  

Dentinal tubules is a small canals extending to the entire width of the dentin  contains cytoplasmic cell process called _____ ____

(a)  

physiologic deposition of dentin at a reduced rate even without obvious external stimuli (Near pulpal area)

(a)  

formed by replacement odontoblasts in response to moderate level irritant such as abrasion, attrition, erosion, trauma, moderate rate dental caries, and some operative procedures

(a)  

results from aging or mild irritation such as slow advancing dental caries causing a change in composition of the primary dentin

(a)  

The most accepted theory of pain transmission o Developed by Brannstrom (1960s) o Small, rapid movements of fluid occurring within the dentinal tubules causing pain sensation on the tooth.

(a)  

are cutting debris of dentin which occludes dentinal tubules during tooth prep

(a)
