This study is an attempt to assess whether the usage of headphones could minimize the nickel ion release from fixed orthodontic appliance compared with hand-held mobile phones. The aim of the study is to validate the hypothesis whether there is a significant variation in nickel ion release from fixed orthodontic appliance among the patients using hand-held mobile phones and patients using mobile earphones.
This is a cross-sectional study where a total of 60 healthy individuals who were undergoing fixed orthodontic treatment in the Department of Orthodontics and Dentofacial Orthopedics, Adhiparasakthi Dental College and Hospital, Melmaruvathur, Chennai, India, and all these individuals were bonded and banded. All of them are class I malocclusion with bimaxillary protrusion. Salivary samples were collected in their regular checkup after two months and 7th, 14th, and 21st days salivary nickel level was evaluated based on their usage of mobile phones with earphones and without earphones.
In this study, paired and independent -tests were used. On basis of statistics results, the mean of nickel release in both male and female participants using mobile phones without earphones were significantly higher than the participants using mobile phone with earphones.
By our study, we concluded that usage of mobile phones with earphones has a significant reduced effect on metal ion release from fixed orthodontic appliance when compared to usage of mobile phones without earphones.
本研究旨在评估使用耳机是否可以减少固定正畸矫治器的镍离子释放，与使用手持移动电话相比。本研究的目的是验证使用手持移动电话和使用移动耳机的患者之间，固定正畸矫治器的镍离子释放是否存在显著差异的假设。
这是一项横断面研究，共纳入 60 名在印度钦奈 Adhiparasakthi 牙科学院和医院正畸和口腔颌面正畸科接受固定正畸治疗的健康个体，所有个体均已粘结和结扎。他们均为 I 类错牙合伴双颌前突。在常规检查后两个月、第 7、14 和 21 天收集唾液样本，并根据他们使用带耳机和不带耳机的手机评估唾液镍水平。
在这项研究中，使用了配对和独立 t 检验。根据统计学结果，使用不带耳机的手机的男性和女性参与者的镍释放平均值明显高于使用带耳机的手机的参与者。
通过我们的研究，我们得出结论，与使用不带耳机的手机相比，使用带耳机的手机可以显著减少固定正畸矫治器中金属离子的释放。
