HOSA Dental Terminology Practice

What does "trituration" mean in the context of dental practices?

1. Mixing silver alloy fillings with mercury to produce amalgam

2. Preparing a dental surgery

3. A method of tooth extraction

4. Coating teeth for protection

The correct answer is: Mixing silver alloy fillings with mercury to produce amalgam

Trituration refers specifically to the process of mixing silver alloy fillings with mercury to create dental amalgam. This procedure is essential in dentistry because amalgam is a commonly used material for filling cavities and restoring teeth. The process involves mechanical mixing, which ensures that the components of the alloy and mercury blend thoroughly, allowing the material to achieve the necessary properties, such as durability and resistance to wear. This results in a strong, stable filling material that can withstand the pressures of chewing and provide effective treatment for dental caries. The other options do not accurately define trituration. Preparing for dental surgery involves various procedures but does not relate to the mixing of materials for fillings. A method of tooth extraction is a separate procedure entirely, focusing on the removal of teeth rather than the preparation of restorative materials. Coating teeth for protection typically involves the application of sealants or fluoride, which is distinct from the amalgamation process described by trituration.
