Physiological response to dental anxiety in children.

The study was conducted among 50 children in the age group of 8-9 yrs. to evaluate the anxiety producing dental procedures in the dental operatory viz. waiting at the reception area, examination in the dental chairs, scaling, polishing, cavity cutting, injection, extraction and post extraction period. The pulse rates were very high during local anaesthesia, extraction, waiting at reception and examination. A significant correlation was observed between the pulse rate and blood pressure.

Iontophoresis. A novel drug administration for extraction of deciduous teeth. A clinical evaluation.

Iontophoresis has a wide range of application in dentistry, one of which is to produce a non invasive technique of analgesia. With the avoidance of needle, in this technique better patient management and good doctor-patient relationship can be built. This study provides an insight into the comparative evaluation of 2%, 4% and 6% lignocaine hydrochloride (plain) in providing analgesia iontophoretically while extraction of deciduous teeth. Patient satisfaction was seen when higher drug concentration and longer duration of iontophoresis was applied.
