DANB's Certified Dental Assistant - Additional Info Sample Questions

For which of the following would you use a Glick #1?

Correct Answer:
to condense gutta percha into a canal opening.

the correct use of a glick #1 instrument is specifically for procedures involved with gutta-percha, a material commonly used in endodontic treatments. the glick #1 is particularly valuable during the final stages of root canal therapy.

gutta-percha is a thermoplastic material used to fill and seal the cleaned and shaped canals inside a tooth’s root. after the cleaning and shaping of the root canal, gutta-percha is heated and then inserted into the canal to fill it completely, ensuring no space is left for bacterial regrowth. once the gutta-percha is placed, it needs to be condensed to adapt to the intricate spaces within the root canal system. this is where the glick #1 comes into play.

the glick #1 has a unique double-ended design featuring a plugger on one end and a flat, spatula-like blade on the other. the plugger end is used to condense the gutta-percha into the canal opening. by applying gentle pressure, the dentist ensures that the gutta-percha is tightly packed into the canal, minimizing the risk of voids that could compromise the seal and potentially lead to treatment failure.

additionally, the spatula end of the glick #1 can be heated and used to remove any excess gutta-percha from the coronal (crown) portion of the canal after the condensation process. this helps in creating a smooth and level fill, which is crucial for the subsequent placement of a permanent restoration, like a crown, on the tooth.

understanding the function and correct application of the glick #1 is essential for dental professionals performing root canal treatments. this tool is not meant for removing debris from a treatment site, removing necrotic tissue, or exploring the pulp cavity. its design and functionality are tailored specifically towards handling and manipulating gutta-percha during the critical phases of a root canal procedure.

It has been determined that a food additive is the agent that caused a patient's dental disease. What type of agent is a food additive?

Correct Answer:
the question asks to identify the type of agent that a food additive, which caused a patient's dental disease, can be categorized under. the correct answer is "chemical."

to understand why, it is essential to recognize the different types of agents associated with health effects or diseases: chemical, physical, and biological. each type of agent encompasses a variety of sources and has distinct modes of affecting human health.

chemical agents are substances that can cause harm when they come into contact with the body. these agents can be natural or synthetic and can be found in the environment, food products, and medications. in the context of the question, food additives represent chemical agents because they are substances added to food to maintain or improve its safety, freshness, taste, texture, or appearance. examples include preservatives, flavor enhancers, and colorants. when these additives lead to health issues such as dental disease, they are acting as chemical agents causing harm through a chemical reaction or toxicity.

physical agents, on the other hand, refer to environmental factors that can physically harm the body without necessarily involving a chemical reaction. these include things like noise, radiation, and extreme temperatures. they do not relate to the scenario described in the question since food additives do not cause harm through physical means.

biological agents include organisms such as viruses, bacteria, fungi, and other pathogens that can cause disease in humans. while these agents are crucial in many health contexts, they are not relevant in the context of food additives, which are non-living chemicals.

lastly, psychological agents are factors that can impact mental health, such as stress or traumatic events, which are outside the scope of the discussion regarding the physical ingestion of substances like food additives.

in summary, food additives are categorized as chemical agents because they are chemical substances that, when ingested, can chemically interact with the body and lead to health issues such as dental disease. understanding this categorization helps in identifying appropriate measures for prevention and treatment of diseases caused by different types of agents.
