Autoclave Procedure For Dental High Speed Handpiece

1.Maintenance

•Daily lubrication to the bearing is absolutely essential for extending its using life.

•After daily use,spray lubricant for 1to 2 seconds by inserting lubricant nozzle all the way into drive air tube.

•If the work is heavy,lubrication should be taken place after every morning and afternoon’s using.

•Lubrication before autoclave.

Caution!

Be sure to hold the handpiece firmly to prevent the handpiece from slipping out by the spray pressure when lubricating.

Supply lubticant until it comes out of the handpiece nose(for approx.2 seconds).Keep the SPRAY can upright.

2. AUTOCLAVE PROCEDURE

After every using,autoclave procedure should be taken as follows

Remove bur from handpiece and clean handpiece by scrubbing with a toothbrush and then use guaze towel to dry

working theory?

Coxo  apex locators works according current resistance theory, from the bur point to apex point there is a resistance “R” shown in the picture, when the bur go deep inside continuetly , “R” become more and more smaller, through the current circuit, this constantly changing will reflect on the screen of apex locator by form of data. When it comes to near the apex point , “R” will become smallest, at this time there will be a warning beep from apex locator, warning the bur can not go deep inside again.ples see the picture shown as such below:

Explanation for the obturation gun

Recently, some of our customers have commented on c-fill (obturation gun).They said that the temperature of obturation gun was not enough hot to dissolve the gutta-percha. The explanation for this problem as follows:

Speak frankly; there are two kinds of gutta-percha on the market. One is like Meta; this kind of gutta-percha of the melting point is lower than others. Working temperature is below 200?.Another kind of gutta-percha is like DENTSPLY. This kind of melting point is a little higher. The working temperature is above 250? and it’s easy cooling. The gutta-percha like DENTSPLY always uses with the wired obturation gun. However our c-fill is only effect on the gutta-percha like Meta.

Patient education

Most of the patient who are given endodontic treatment, are often curious and and interested in their treatment.

For such patients following information should be transferred to the patient in anticipation of frequently asked questions.

Who performs an endodontic therapy?

Generally, all dentists receive basic education in endodontic treatment but an endodontist is preferred for endodontic therapy. General dentists often refer patients needing endodontic treatment to endodontists

Who is an endodontist?

An endodontist is a dentist who undergoes a special training in diagnosing and treating the problems associated with inside of the tooth. To become specialists, they complete dental school and additional two or more years of advanced training in endodontics. They perform routine as well as difficult and very complex endodontic procedures, including retreatment of previous root canals that have not healed completely, as well as endodontic surgery.

What is endodontics?

Endodontics is the diagnosis and treatment of inflamed and damaged pulps. Teeth are composed of protective hard covering (enamel, dentin and cementum) encasing a soft living tissue called pulp (fig.1.1) Pulp contains blood vessels, nerves, fibres and connective tissue. The pulp extends from the crown of the tooth to the tip of the roots where is connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and development.However, once a tooth is fully mature it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it.

How does pulp become damaged?

Numbers of ways which can damage the pulp include tooth decay, gum diseases, injury to the tooth by accident (fig.1.2)

Why do I feel pain?

When pulp becomes infected, it causes increased blood flow and cellular activity, and pressure cannot be relieved from inside the tooth. This causes pain. Pulp can even die without causing significant pain.

How can you tell if pulp is infected?

When pulp gets inflamed, it may cause toothache on taking hot or cold, spontaneous pain, pain on biting or on lying down. On occasion a damaged pulp is noticed by drainage, swelling, and abscess at the root end (fig1.3.)

Sometimes, however, there are no symptoms.

Why do I need root canal therapy?

Because tooth will not heal by itself, the infection may spread around the tissues causing destruction of bone and supporting tissue. This may cause tooth to fall out. Root canal treatment is done to save the damaged pulp by thorough cleaning and shaping of the root canal system and then filling it with gutta-percha (rubber like) material to prevent recontamination of the tooth. Tooth is permanently restored with crown with or without post.

What are alternatives to root canal therapy?

IF tooth is seriously damaged and its support is compromised, then extraction is only alternative.

What is root canal procedure?

Once the endodontic therapy is recommended, your endodontist will numb the area by injecting local anesthetic.

After this rubber sheet is placed around the tooth to isolate it. Then the opening is made in the crown of the tooth and very small sized instruments are used to clean the pulp chamber and root canals (fig.1.4) After thorough cleaning and shaping of root canals (fig.1.5), they are filled with rubber like material called gutta-percha, which will prevent the bacteria from entering this space again (fig.1.6) After completion of endodontic therapy, the endodontist places the crown or other restoration so as to restore the tooth to pull function. (fig1.7)
