Composite Resin Restorations Have Brought Us a Bright Future

One of my favorite treatments is Direct-bonding for the small defect in an anterior tooth by composite resin with an adhesive system.

I prefer to preserve teeth rather than drilling or tooth extraction. Direct bonding which is based on operative dentistry is esthetic and constructive.

Most importantly, patients are very glad of it.

I think that is because not only there is no sense of losing a tooth but also there is a sense of recovering a tooth.

The patient who comes to the dental clinic with the main complaint of a small chip in the anterior tooth, ordinary wants esthetic restoration.

Now, we can make it as a dentist!

This is not a superior case, conventional, not rare.

Since this is not a case presentation, I will not explain the details.

The following is a list of the dental materials and instruments I used.

FineEtch37; SPIDENT as selective etching at the enamel

Scotchbond Universal;3M ESPE as a bonding agent

Filtek Supreme Ultra A2E, A3B;3M ESPE as composite resin

OptraSculpt Pad;IvoclarVivadent as instrument

Opti1step Polisher; Kerr as finishing and polishing polisher

I didn’t use any other special items.

The Sealer-Puff After the Root Canal Obturation, the Relationship Between Root Canal Irrigation

The sealer-puff is a characteristic appearance of sealer overflow outside the apical foramen on the confirmatory dental photograph after root canal filling. This is caused by a small amount of sealer overflowing outside the apical foramen when the dentists pressurize the area around the apical constriction to achieve a tight root canal filling. It is also caused by sealer penetrating the lateral branches of the apical-delta due to pressure at the apex. The sealer puff is, after all, an overflow of foreign material into the periapical tissue of the root apex. Of course, dentists must always try to prevent foreign material to overflow from the root apex into the apical periapical tissue. However, if we take into account the cause of sealer puffs, we can evaluate them from a different perspective. Sealer puffs are... The area around the root apex is properly cleaned and free of debris, ensuring the patency of the root canal. And Be caused by the application of a good flow of s...

The Agitation for Root Canal Irrigation

An important aspect of root canal cleaning is just disinfection, especially at the root apex. This consists of removal of the smear layer of the dentinal wall and disinfection with sodium hypochlorite solution in the apical delta. Normally, dentists perform positive pressure irrigation using a syringe for root canal irrigation. They use saline solution, hydrogen peroxide solution, EDTA, or sodium hypochlorite solution as the cleaning solution. If the needle is thin enough to rinse deep into the root canal, dentists will usually feel that can clean the root canal. However, the reality is that the cleaning is not satisfactory. This is because only positive pressure irrigation makes it difficult to exert the chemical action of the irrigants. In particular, a narrow path such as the apical delta is difficult for the cleaning solution to reach. Therefore, it will be necessary to use some other method in addition to positive pressure washing. The agitation of root canal irrigation is. T...

Let's Consider Root Canal Irrigation

In my opinion, an extremely important step in root canal treatment is root canal irrigation. Cleaning the inside of the root canal is a more difficult procedure than the dentist may think and, in practice, often results in inadequate cleaning. Root canal irrigation is not as simple as simply placing fluid into the root canal. As the name "irrigation" implies, it is the act of physically and chemically removing the dirt inside the root canal using a cleaning solution - some kind of liquid. The root apex is the most important area of the root canal where cleaning is required. In root canal treatment, aseptic preparation of the root canal by the dentist can prevent apical periodontitis. Once the root canal has been ideally enlarged with a NiTi file, it must then be thoroughly cleaned; if there is debris, it should be physically flushed out, and if there is inorganic or organic residue, it must be chemically cleaned. In addition, the root canal must be perforated and patency mus...

All thumbs! my dental practice, meanwhile in Japan.
