Radiology
The wavelength of X-ray photon depends upon kilo voltage.
The wavelength of X-rays is inversely proportional to their energy, and the
energy of X-ray photons is determined by the kilo voltage (kV) used in the X-ray
tube. Higher kV results in higher energy and shorter wavelength photons, which
are more penetrating and are used for imaging denser tissues, while lower kV
results in lower energy and longer wavelength photons, which are less
penetrating and are used for imaging softer tissues. The other factors mentioned
(milli amperage, distance between source and object, and quantity of electrons
in the cathodic stream) affect the intensity of the X-ray beam but not the
wavelength of the photons.

NEETMDSSilicate-bonded investments use a silica sol binder, and the setting process involves the loss of water and alcohol, leading to a high amount of contraction during both setting and burnout phases. This contraction is compensated for by the expansion of the investment material.

It is also used to treat ventricular tachycardia and to perform nerve blocks Dosage Of Local Anesthesia: 1) Safety dose of 2% Lignocaine is 4.5mg/kg without a Vasoconstrictor Without a Vasoconstrictor 300 mg (maximum dose) 2) Safety dose of 2% Lignocaine is 7mg/kg with a Vasoconstrictor With a Vasoconstrictor – 500 mg (maximum dose) 3) As 1ml of 2% Lignocaine contains 20mg – Where the Maximum safety dose being 300 mg So 15 ml of Drug can be given safely 4) 1:1,00,000 concentration means 1 part of Adrenaline is 1,00,000 parts of Solution Safety Dose of Adrenaline for Dental Use in normal patients is 0.2 mg – which means 20 ml of LA can be given to normal patients containing Adrenaline For cardiac Patients the safety dose of Adrenaline is 0.04mg – Which means 4ml of LA can be given to Patients with cardiac problems containing Adrenaline 5) If the concentration of LA is 1:50,000 – 10 ml of LA can be given safely
