Indications for Coronal Polishing - ANSWER - Before the implantation of dental
sealants - Before the placement of dental dams - Before the cementation of
orthodontic bands - Before the cementation of crowns and bridges - Before the
application of acid etching solution (if the manufacturer recommends it)
Contraindications for Coronal Polishing - ANSWER - when there are no stains
present - individuals who are at high risk for dental caries (for example, bottle
caries, root caries, thin demineralisation enamel) - sensitive teeth - teeth that have
recently erupted - mineralisation of the tooth surface may be incomplete B/C
To answer your question, endogenous stains are stains that originate from within
the structure of the tooth.
,Excessive amounts of fluoride during the process of tooth formation, as well as
drugs used by either the mother or the kid during the process of tooth development
(Tetracycline among them).
It is not possible to remove by polishing.

Examples of Extrinsic Stains include the following: ANSWER: black stain, brown
stain, yellow stain, tobacco stain, green stain, dental plaque agents, food and drink,
Nasmyth's membrane, and other substances.
Examples of Intrinsic Stains: ANSWER Pulpless teeth, Tetracycline antibiotics,
dental fluorosis, faulty tooth development, and silver amalgam are all examples of
intrinsic stains.

When it comes to aesthetic repairs, which prophy adhesive paste is not
recommended? Regular prophylaxis paste is the answer.
During the restoration process, it is recommended to make use of low-abrasive
pastes such as micron-fine sapphire paste, diamond paste, or aluminium oxide
paste.
, The application of a bigger quantity of the agent results in a greater degree of
abrasion. This is one of the factors that determines the rate of abrasion.
When the pressure is lower, there is less abrasion produced.
The rotation of the cup should be slowed down so that there is less abrasion.
As for the order in which polishing should be done, the answer is that porcelain and
aesthetic restorations should be polished first.
