True
It is critical for the dental professional to be in control and properly positioned during impression making to ensure everything is under control.
True
Impression evaluation involves looking for specific characteristics such as a bevel on the preparation.
True
Hydrophilic impression materials are harder to pour models with compared to hydrophobic materials.
True
Having a hydrophobic impression material can lead to gaps in the final impression due to the way it beads up.
True
Patient comfort techniques play a crucial role in ensuring accurate dental impressions.
False
It is more important to make a good, sharp impression than to pour the model correctly.
False
Using a bubbleizer on a hydrophobic material makes the surface more hydrophobic.
False

True
The traditional technique for dental impressions involves placing a small piece of cellophane in the tray over the material seated in the mouth.
True
In the traditional technique, after setting the cellophane in the tray, you remove it and have an indent where all the teeth were, but no room around the teeth.
False
The technique of using light body material squished into the mouth against the teeth can potentially displace tissue, blood, and capture the dental impression.
True
One of the techniques mentioned involves grinding out some room in the initial impression to add more wash material.
True
Using light body material in dental impressions is highly recommended by the faculty in the clinic.
False
There are various variations to the traditional technique, including drilling holes in trays and injecting body material around teeth.
True
Materials used for dental impressions come in varying forms, such as different consistencies and compositions.
True
The putty wash technique involves adding putty material to the initial impression without any modifications.
False
Drilling holes in trays and injecting body material around teeth is not considered a valid approach in dental impression techniques.
False
In the traditional technique, the light body material is squished into the mouth against the teeth, displacing tissue and blood to capture the dental impression.
True
The putty wash technique involves adding putty material to the initial impression without any modifications.
False
The putty wash technique involves adding putty material to the initial impression without any modifications.
False
Using light body material in dental impressions is highly recommended by the faculty in the clinic.
True
Hemostatic agents are crucial in dental impression techniques to control bleeding and ensure clear impressions.
True
Using light body material in dental impressions is highly recommended by all faculty members in the clinic.
False
In dental impression techniques, drilling holes in trays and injecting body material around teeth is considered a valid approach.
False
Injecting body material around teeth is not considered a valid approach in dental impression techniques.
False
Hemostatic agents are commonly used in traditional dental impression techniques to improve impression accuracy.
False
It is recommended to box the impression when first using new materials in dental impression techniques.
False
The PVS material used in dental impressions is different from vinyl polyester.
False
A regular or heavy body material is mixed using an auto mixing machine in dental impression techniques.
True
The auto mixing gun is used to inject heavy body material during the dental impression process.
False
The machine used for mixing heavy body material in dental impressions usually has a timer built into it.
True
Using light body material in dental impressions is not recommended by the speaker in the passage.
False
The putty wash technique involves removing putty material from the initial impression and adding a different material for modifications.
False
Hemostatic agents are irrelevant in the context of dental impression techniques according to the passage.
False
Heavy body material is typically mixed using a machine with a built-in timer for precise mixing.
True
The speaker emphasizes the importance of using heavy body material over light body material for better dental impressions.
False
The putty wash technique involves modifying the initial impression before adding putty material.
False
Hemostatic agents are commonly used in traditional dental impression techniques to improve impression accuracy.
True
Patient comfort techniques are irrelevant when making dental impressions.
False
According to the passage, the key thing to watch out for when using disposable syringes is that they are often manufactured poorly, resulting in plastic bits at the end.
True
In dental impression techniques, it is recommended to spread separate groups of materials around a pad for efficient mixing.
False
If light body material has been in the mouth for too long, it may lead to an inaccurate impression.
True
In dental impression techniques, placing the catalyst directly on the base is considered a correct method for ensuring a good impression.
False
Using a heavy body material with a timer built into the mixing machine is recommended for making precise dental impressions.
False
Using a hydrophobic impression material can lead to gaps in the final impression.
True
The putty wash technique involves adding putty material to the initial impression without any modifications.
False
It is highly recommended by the faculty to use light body material in dental impressions.
