While applying DC, the important parameter for therapeutic purpose is
🅐. Current intensity
🅑. Circuit resistance
🅒. Current density
🅓. The duration of application
In iontophoresis the total number of ions introduced into the tissue proportional to
🅐. Current
🅑. Current density
🅒. Time of application
🅓. Both b & c
For iontophoresis the positively charged ions should be kept at
🅐. Anode
🅑. Cathode
🅒. Any electrode
🅓. Both the electrodes
The factor/factors important for penetration of ion into the tissue is/are
🅐. Specific conductivity of solution
🅑. pH of solution
🅒. Precipitation formed by ions
🅓. All of the above
The mechanism of wound healing by electrical stimulation is supposed to be due to
🅐. Skin battery
🅑. Enhanced DNA and protein synthesis
🅒. The migration of epithelial and connective tissue cells
🅓. All of the above
What should be the sequence of application of current for an infected wound?
🅐. Cathode on wound, < 1ma current, change of polarity of electrode
1. 🅑. Anode on wound, < 1ma current, change of polarity of electrode
2. 🅒. Cathode on wound, > 1ma current, change of polarity of electrodes
  🅓. Anode on wound, > 1ma current, change of polarity of electrode
The duration of anesthesia effect by application of anesthetic agent through iontophoresis is
🅐. 2 minutes
🅑. < 5 minutes
🅒. Within 15 minutes
🅓. 20 minutes
What is the best therapeutic use of iontophoresis?
🅐. As local anesthesia
🅑. To apply antibiotics
🅒. To apply anti inflammatory drug
🅓. For treatment of hyper hydrosis
Which is not true for iontophoresis
🅐. Eliminates first pass metabolism
🅑. Uncontrolled drug delivery
🅒. Avoid pain that accompanies injection
🅓. Decrease risk of infection.
Which iontophoresis is used for hyper hydro sis
🅐. Metallic silver
🅑. Glycopyrronium bromide
🅒. Xanthenes nicotinamide
🅓. Vinc alkaloid
