Yes, APF (acidulated phosphate fluoride) is generally safe for crowns and bridges as it helps prevent tooth decay. However, prolonged exposure to high concentrations of fluoride may cause discoloration of certain dental materials like resin-based crowns or bridges. It is recommended to consult with your dentist to ensure proper usage and avoid any potential issues.

Atomic packing factor for Bcc?
atomic packing factor (APF) or packing fraction is the fraction of volume in a crystal structure that is occupied by atoms. It is dimensionless and always less than unity. For practical purposes, the APF of a crystal structure is determined by assuming that atoms are rigid spheres. For one-component crystals (those that contain only one type of atom), the APF is represented mathematically by where Natoms is the number of atoms in the crystal, Vatom is the volume of an atom, and Vcrystalis the volume occupied by the crystal. It can be proven mathematically that for one-component structures, the most dense arrangement of atoms has an APF of about 0.74. In reality, this number can be higher due to specific intermolecular factors. For multiple-component structures, the APF can exceed 0.74.
Show that the atomic packing factor for the Bcc crystal structure is 0.68?
In body-centred cubic structure,The no. of atoms per unit cell= 2Volume of 2 atoms (spherical)=2*(4/3)πr3We know the radius of atom in BCC isr = a√34Volume occupied by the atoms per unit cell(v) = 8πa√33 4v == 8πa33√3------- ---------3 4*4*4Volume occupied by the atoms per unit cell(v) =πa3√3----8Volume of the unit cell for a cubic system(V) = a3Atomic packing factor (APF) =(πa3√3/8)--------------a3√3(or) APF =π---------8APF = 0.68Therefore, we can say that 68% volume of the unit cell of BCC is occupied by atoms and remaining 32%volume is vacant.Thus the packing density is 68%.

How do you calculate APF of HCP?
The atomic packing factor (APF) of a hexagonal close-packed (HCP) structure is calculated by taking the volume of atoms in a unit cell divided by the total volume of the unit cell. For HCP, the APF can be determined using the formula: APF = (3 * sqrt(3) * (0.25)) / (2 * sqrt(2)) This simplifies to APF = 0.74
How many forms of fluoride are there?
Well, I don't have a number for you. I can tell you that in Dentistry we use 3 main types of fluoride for therapeutic use. NaF also known as sodium fluoride APF also know is acidulated phosphate fluoride SnF also known as stannous fluoride Fluoride may occur in many other forms that I am not aware of, but these are the forms that are used to produce clinical results. I couldn't tell you how many forms of fluoride there, but if you are concerned that you need fluoride for your teeth, don't worry, If you get your teeth cleaned the recommended twice a year, the dentist should do a fluoride treatment. That is plenty. Also, If you live in the city, you are getting additional fluoride because most cities add a small amaount of fluoride to their drinking water resurves for this purpose, not to mention it helps keep the water you are drinking healthy. i thought there was like 600 and even more
Atomic packing factor of nacl?
Na Cl has an IPF factor not APF as it is compound and APF refer to atomic packing factor, not ionic packing factor.
