| Abstract | ||
| Several studies were done on magnetic attachment which used for retention of overdentures and these magnetic attachments fixed above the oral mucosa on dental implant or on precious metal root cap by cast bonding or cementing, these magnetic attachment may have effect on oral microorganism. This in vitro study investigated the effect of different static magnetic field strength on some oral microorganism. Oral swabs were taken from the lateral border of the tongue and buccal mucosas of the check from 10 students, growing culture were examined carefully and colony morphology was recorded. Gram stain and Lactophenol stain were used when suspected Fungi, isolated colonies were sub-cultured and these colonies identified by using different API systems, Streptococci mitis, Streptococci salivarius, Staph. aureus, Enterococci and Candida albicans identified and cultured and Then the effect of (50, 150,500,20,000 Gauss) static magnetic field strength were investigated on growth rate of these microorganism. The values obtained in this study were subjected to Analysis of Variance (ANOVA). Indicated that static magnetic field had an inhibitory effect on the growth rate of Strep. mitis and Strep. salivarius when the magnetic field strength used greater than (150 Gauss) at both South and North poles statistical analysis shows significant differences with control group. While in Enterococci and Staph. aureus and Candida albicans it showed an inhibitory effect on growth rate at North Pole with increasing in field strength above (150 Gauss) , while at South Pole it showed stimulatory effect on growth rate of these microorganisms with increasing field strength, both Poles showed significant differences with controlled group. While at (50 Gauss) field strength the results indicated no clear effect on culture growth rate for all microorganisms in the study. This study indicated that field strength of static magnetic greater than (50 Gauss) shows affect on growth rate of the oral microorganism which may affect the oral environment | ||
