BACKGROUND
Nowadays mobile phone is very popular, causing concern about the effect it has on people's health. Parotid salivary glands are in close contact to cell phone while talking with the phone and the possibility of being affected by them. Limited studies have evaluated the effect of cell phone use on the secretions of these glands; so this study was designed to investigate the effects of duration of mobile phone use on the total antioxidant capacity of saliva.
METHODS
Unstimulated saliva from 105 volunteers without oral lesions collected. The volunteers based on daily usage of mobile phones were divided into three groups then total antioxidant capacity of saliva was measured by Ferric Reducing Ability of Plasma (FRAP) method. Data were analyzed by SPSS software version 19. ANOVA was used to compare 3 groups and post-hoc Tukey test to compare between two groups.
RESULTS
Average total antioxidant capacities of saliva in 3 groups were 657.91 µmol/lit, 726.77 µm/lit and 560.17 µmol/lit, respectively. The two groups had statistically significant different (P = 0.039).
CONCLUSION
Over an hour talking with a cell phone decreases total antioxidant capacity of saliva in comparison with talking less than twenty minutes.
背景
如今手机非常普及，这引发了人们对其对健康影响的关注。在使用手机通话时，腮腺与手机紧密接触，存在受其影响的可能性。有限的研究评估了手机使用对这些腺体分泌的影响；因此，本研究旨在调查手机使用时长对唾液总抗氧化能力的影响。
方法
收集了105名无口腔病变志愿者的非刺激性唾液。根据志愿者的手机每日使用情况将其分为三组，然后采用血浆铁还原能力（FRAP）法测量唾液的总抗氧化能力。数据用SPSS 19.0软件进行分析。采用方差分析比较三组，采用事后Tukey检验比较两组。
结果
三组唾液的平均总抗氧化能力分别为657.91µmol/升、726.77µmol/升和560.17µmol/升。两组之间存在统计学显著差异（P = 0.039）。
结论
与通话少于20分钟相比，使用手机通话超过一小时会降低唾液的总抗氧化能力。
