Question

Which acid is used in dentistry and orthodontics as an etching solution?
A. Tartaric acid
B. Phosphoric acid
C. Carbonic Acid
D. Acetic acid

Answer 1

Hint:
The etching solution is an acidic solution which can be added directly into the enamel. The enamel is a covering which is present around the surface of the teeth and acid solution when introduced lets the sealing mixture act as adhesive for the action of the teeth.

Complete step by step answer:
The etching solution that is commonly used by dentists and orthodontists is phosphoric acid. The phosphoric acid can demineralize the enamel and cleans the surface of the teeth. It makes the surface of the teeth rough when introduced directly and the teeth structure becomes more porous. The porosity helps in the easier entry of the medicine on the teeth during a surgical procedure.
The process of sealing the teeth is easier as the sealant used can be retained around the teeth. The action of phosphoric acid is also responsible for the removal of plaque that is present in between the teeth so that the procedure can take place smoothly. Therefore, if there is any surgical process performed on the teeth it is important to use the etching solution.
The phosphoric acid is used as it does not damage the internal structures of the mouth after the introduction. The orthodontists use this to make the teeth porous to ensure treatment occurs in the right manner and can cross the barrier of enamel. This is why the etching solution is used prior to the

Note: Orthodontists and dentists need to make the region of surgery sterilized from all kinds of plaques and hence this phosphoric acid acts as a really prominent chemical for that purpose. This mainly acts as an initiator for dental surgery.
