Abstract
Aim: In current studies, it is reported that exposure to electromagnetic field (EMF) is related to numerous illnesses. Important parts of our bodies, oral and dental tissues can also be influenced by the EMF. In this study, it was aimed to determine possible negative impacts of EMFs on dental enamel hardness and to test the efficiency of the antioxidant agents against possible adverse effects.
Methodology: In this study, 4-month-old 32 Winster strain Albino rats were used, each weighing 250-300 gr in average. In total, 40 teeth were used from these 32 rats. These teeth were classified into four groups. Group 1 was determined as the control group, and Group 2,3, and 4 were exposed to EMF measured as 2.48 μT magnetic field intensity and 80.3 V / m electric field intensity for 52 days. Ganodermalucidum (20 mg/kg/ day) was applied to the Group 3 together with the EMF. Melatonin (10 mg/kg/ day) was applied to the Group 4 together with the EMF. The teeth pulled out after the euthanasia were embedded into acrylic blocks and micro-hardness test was applied. The normality of the variables was analyzed through the Shapiro-Wilk test. After the homogeneity test, one-way analysis of variance (ANOVA) was used to compare surface micro-hardness (p<0.05).
Results: As a result of the conducted statistical analyses, there was statistically no significant difference among the groups concerning micro-hardness (P>0.05).
Conclusions: It was determined in our study that 52-day exposure to 2.48 μT EMF did not cause any micro-hardness change in the tooth enamels of the rats. It was also observed that the used antioxidant agents did not cause any significant difference.
