Abstract

The study aimed to determine the impact of energy for the north and south magnetic poles on the the growth of bacteria isolated from cases of tooth decay, 68 swabs were collected from surfaces of faulty tooth, the detected of Staphylococcus aureus, Staphylococcus epidermids and Streptococcus mutans for isolation and then diagnosed using phenotypic diagnostic methods and biochemical tests. The results showed that 28 isolates (41%) were S. aureus and 23 isolates (34%) were S. epidermids and 17 isolates (25%) were Streptococcus mutans.

Exposed isolates to magnetic field poles of north & south and two together to see the effect of polarity on the growth and vitality of bacterial isolates, the results showed that north pole has been negative effect on the growth of bacteria, reduce numbers and inhibition growth with varying degrees while south pole showed positive effect in increasing numbers of bacteria while gave poles together moderate effect between the north pole and the south pole

           With regard to the impact of antibiotics such as cephalothin, erythromycin, penicillin, tetracycline and novabiocin on growth of bacterial isolates, the results showed that S. aureus was resistant to the most antibiotics, while varied ratios inhibition for other isolates, and when studying the effect of the magnetic field with antibiotic together on the growth of isolates, there was an increase the sensitivity of the bacterial isolates to the antibiotic under magnetic field compared to the sensitivity toward antibiotic alone..
