Answer:

During the restoration, it is not possible to use base materials with great pigmentation due to the aesthetic compromise, such as calcium hydroxide.

In addition, in this clinical situation, OZE, non-resistant / non-hybrid vitreous ionomethanes and pastes that could alter or irritate the dental pulp through the dentin tubules are contraindicated.

Explanation:

In this case, I would place a dentin composite paste, which has the same pigment as the patient's dentin, otherwise, a vitreous ionomer modified with dual-curing resins could be used as a base, where it assures us the possible retouching in it. session and also the complete setting protecting the dentin, obliterating the tubules and having a covalent chemical union with the dentin ... Above these types of base it is ideal to make a selective etching of the enamel with phosphoric acid, placement of the adhesive (resin waterproof) and finally the composite that perfectly matches the patient's color.

The study of teeth is called odontology.

In humans, there are 4 sets of teeth. These sets are as follows:-

  • Incisors
  • Canine
  • Molar
  • Premolar

During the restoration, it is not possible to use base materials with great pigmentation due to the aesthetic compromise, such as calcium hydroxide. Most part of the teeth is made up of calcium hydroxide.  In this clinical situation, OZE, non-resistant / non-hybrid vitreous iodomethane, and pastes that could alter or irritate the dental pulp through the dentin tubules are contraindicated.
