What are the types of dental amalgam?

Currently, three types of dental amalgam alloys are available: lathe cut, spherical and admixed (Figure 6.6). Their handling characteristics are all very different and it is important that they are manipulated correctly when used in the clinic for optimal performance of the set product (see pp.

How does dental amalgam work?

When placing dental amalgam, the dentist first drills the tooth to remove the decay and then shapes the tooth cavity for placement of the amalgam filling. Next, under appropriate safety conditions, the dentist mixes the encapsulated powdered alloy with the liquid mercury to form an amalgam putty.

How is dental amalgam made?

Dental amalgam is produced by mixing liquid mercury with an alloy made of silver, tin, and copper solid particles. Small quantities of zinc, mercury and other metals may be present in some alloys. This combination of solid particles is known as amalgam alloy.

What is the purpose of fissure sealants?

Fissure sealants are a white or clear composite resin, similar to a white tooth filling. The sealants provide a barrier against bacteria that can cause plaque. They are designed to prevent tooth decay and cavities.

How does ultrasonic scaler work?

Ultrasonic scalers work via vibration. The speed of the vibrations knock the plaque and tartar off your teeth and do so in a fast and effective manner. There is no scraping metal against your teeth, and the tips are tiny enough to easily access areas where manual tools may have difficulty.

How long does dental fissure sealant last?

According to the NHS, fissure sealants can last anywhere from five to 10 years.

Can ultrasonic scaler damage teeth?

Conclusions: The results of this study suggest that ultrasonic scaling can cause further damage to teeth with enamel cracks, early caries and resin restorations. Therefore, accurate identification of tooth conditions and calculus before the initiation of ultrasonic scaling is necessary to minimize damage.

What is the disadvantages of the ultrasonic scaler?

However, the one downside to the ultrasonic scalers is that patients with recession of the gums can experience sensitivity. The sensitivity is caused by the vibrations of the scaler against the exposed tooth surface that was once covered with gingival tissue.

What is amalgam called?

Answer : Amalgam is an alloy of mercury with one or more metals. Sodium along with liquid mercury is known as sodium amalgam. Amalgam of mercury with tin, silver and zinc is widely used in dental filling.

How do you remove fissure sealant?

At an irradiation intensity of 1.3 J/cm2, pit and fissure sealants are completely removed without visible damage to the underlying enamel. At intensities above 1.5 J/cm2, incident laser pulses remove the resin layer while at the same time preferentially etching the surface of the enamel.

Can fissure sealants fall out?

Sometimes the sealant falls off — this will usually happen within 6 months. It is a good idea to visit the dentist regularly so they can make sure the sealant is in good condition as part of your routine dental check-up. It can wear down over the of years and will then need to be reapplied.
