Assessment of cell phone effect on dental socket healing in rat.

BACKGROUND Electromagnetic waves can cause biological effects on repair process. Due to the proximity of the jaw bone and the soft tissue around it in a part of the face with which it has the closest contact during the cell phone use, this study aims to investigate the effect of mobile waves on socket healing after tooth extraction in rats. MATERIAL This experimental study was conducted on 32 rats. The case group was exposed to a 900 MHz frequency electromagnetic field for 30 min/d. Sacrificed eight rats from the case group and 7 rats from the control group on day 14, and 8 rats from the case group and 7 rats from the control group were sacrificed on day 28 at the end of the radiation period and CBCT and microscopic examinations on the maxillary bones and soft tissue were performed. RESULTS According to the findings, the healing process was significantly different in two groups in terms of the percentage of new bone formation on day 14 after the end of radiation (p = 0.014). The other measured parameters including the degree of inflammation, thickness of the formed bone, number of osteoblasts and Gray scale had no significant difference between the two groups in any of the 14-day and 28-day intervals. CONCLUSIONS The results of this study showed that intermittent exposure to high frequency electromagnetic fields over a period of 20 hours has no significant effect on the healing process of alveolar socket after tooth extraction in rats.
