Is a dental mirror concave or convex?
concave mirrors are used as dental mirrors. this is because concave mirrors produce highly magnified images which is useful in obtaining larger view of teeth and gums.
What are Interlocking shapes?
- Interlocking shapes (like Lego) fit together because of their shape. Dovetail joints in drawers, dental fillings and folded seams are some examples.
Which electromagnetic wave has the highest penetrating power?
ultra voilet rays are characterized with high penetrating power ============================= The EM radiation with the highest penetrating power would be the flavor with the highest frequency/shortest wavelength. Those are the waves we call "gamma rays". A moment's thought will remind you that X-rays are more penetrating than ultraviolet rays are ... otherwise we'd be getting dental ultraviolets instead of dental X-rays.
What is a cavitron?
A handheld dental device for scaling teeth via ultrasound, during routine cleanings. It shoots ultrasonic waves, and a water jet to clear away debris... It makes a high-pitched sound, which can remind people of the dreaded high-speed drill.

What are the chemical and physical properties of dental amalgam?
coefficient of thermal expansion chemical would be Galvanism,
The material the dentists use to fill up the cavities in teeth should have the same coefficient of expansion as the tooth itself what happens if they are different?
All dental filling materials have a different coefficient of thermal expansion than natural tooth structure. Some are closer than others, but none are identical. A couple of things come into play -- one is that teeth flex slightly -- if teeth were totally brittle, and had no "give" they would always break as soon as there was a temperature difference. A second factor is that coefficient of thermal expansion depends on the amount of material -- i.e. larger/wider/longer fillings will shrink and expand more than smaller ones. In practice, fillings tend to be fairly small, so the expansion/contraction is small, and usually not clinically significant. The third major factor is that they still do expand/contract at different rates, and sometimes the result is microleakage. Microleakage is the leakage that happens between the filling material and the liner or adhesive layer that is on the tooth. Again, this is typically not a clinically significant problem, and has been researched quite extensively. The closest class of materials in terms of coefficient of thermal expansion are glass ionomer materials, followed by gold, then amalgam, and the worst is composite (at least in terms of thermal expansion). When choosing a material for a restoration, there are multiple factors, and there is not a "one size fits all" or a single best material that is perfect in all cases.
Can you make expansion of dental arch if there is no cross bite?
Why would you need to then? Expansion of dental arch is to relieve crowding, so that when the decidious tooth comes out, there will be room for the permanent tooth that is following close behind. Very important to check articulation, so as not to cause TMJ problems.
What is an orthodontic expansion?
rapid or slow , bony or dental or in combination to cover inter arch or intra arch occlusal or facial discripancies
What is a sample sentence of contraction and possession with an apostrophe?
Example sentence for contractions:I can't go with you, I've got a dental appointment.Example sentence for possession:The dentist's office is on Third Street.
Can hyperventilation cause someone to hear too loudly and affect vision can metal dental implants add to hyperventilation does metal attract oxygen can the size of implants affect breathing?
1. Yes, hyperventilation can affect hearing and vision. 2. No, dental implants can not unless the person is anxious and then hyperventilates. So this becomes a mental issue. 3. No. These types of dental implants can not attract oxygen. Otherwise all of us who have them would have similar problems. 4. Perhaps the size can affect breathing. Talk to your dentist. Perhaps there is swelling from these if they are new.
Can adults wear teeth expander?
Expansion of maxillary arch can be achieved in adult. However, actual bone movement will be much less compared to treatment in growing patient. Satisfactory dental movement can still be achieved. If large amount of expansion is needed, surgical assistance will be needed. Some new types of braces (self-ligating) are more efficient in expanding dental arches. Expansion can only give moderate space to relieve crowding. It has little effect on reducing protrusion or overbite (buck teeth).
What are some affects of dental burs on an elderly person?
A dental bur isn't going to affect an elderly person in any different way than a younger person, provided their teeth are in good condition.
How does illicit drug use affect dental surgery?
Answer Depending on what drugs you are using the dental surgeron may not be able to put you to sleep because you have a high rate of tolerence to drugs and you should tell the surgeon before he works on you.
Is biting your cheek a side effect of dental anaesthesia?
no its not a side affect, its an affect of your ignorance. your not supposed to chew until it wears off.unless it lasts a week more than the 5 hours dentists claim it lasts.
How do you abbreviate dental?
You dont dental is dental. no abbreviations.
why should the arnalgam used in dental fillings have the same average cofficient of expansion as a tooth what would occur if they were mismatched?
he reason why dental amalgam (a mixture of metals used in dental fillings) should have the same coefficient of expansion as a tooth is because the coefficient of expansion is a measure of how much a material will expand or contract when exposed to changes in temperature. If the coefficient of expansion of the dental amalgam is different from that of the tooth, it can cause problems. If the coefficient of expansion of the dental amalgam is greater than that of the tooth, the filling will expand more than the tooth when exposed to heat, and this can cause the tooth to crack or fracture. Similarly, when the filling contracts more than the tooth when exposed to cold, it can cause the tooth to become loose or fall out. On the other hand, if the coefficient of expansion of the dental amalgam is less than that of the tooth, the filling will not expand as much as the tooth when exposed to heat, and this can cause the filling to become loose or fall out. Similarly, when the filling contracts less than the tooth when exposed to cold, it can cause the tooth to crack or fracture. Therefore, it is important for the coefficient of expansion of the dental amalgam to be as similar as possible to that of the tooth in order to prevent these problems from occurring. In order to achieve this, dentists use a special type of dental amalgam that is specially formulated to have a coefficient of expansion that is similar to that of the tooth.𝘩𝘵𝘵𝘱𝘴://𝘸𝘸𝘸.𝘥𝘪𝘨𝘪𝘴𝘵𝘰𝘳𝘦24.𝘤𝘰𝘮/𝘳𝘦𝘥𝘪𝘳/372576/𝘮𝘶𝘣𝘪𝘳𝘪𝘨𝘪/
