Areca nut is chewed by itself and in various scented preparations. Areca nut chewing is widely practiced in many parts of Asia, including India. Users often consider it harmless and report a sense of well-being, but evidence has shown that it is far from harmless and can have multiple oral health implications such as oral submucosal fibrosis posing difficulty in opening mouth and carcinogenesis. Studies in India have reported increasing prevalence of this habit among schoolgoing children. The objectives of the study were to find the effect of areca nut chewing on mouth opening, compare it with the children not having this habit, and to find correlation between maximal mouth opening (MMO) and months of areca nut chewing.
The aim of this study is to find the effect of areca nut chewing on MMO in schoolgoing children in Ahmedabad.
An observational analytical study was conducted across various schools of Ahmedabad.
A total of eighty male students of 12-14-year-old were included in the study. Group A included children having the habit of eating areca nut for 6 months or more, and Group B had children who did not have the habit of areca nut chewing. Children who had just started eating for <6 months were excluded from the study. MMO was calculated as distance from the edge of the upper incisor teeth to the edge of the lower incisor teeth using a calibrated fiber ruler.
Statistical analysis was performed by SPSS software version 20.0, with level of significance set at 5%.
Mean and standard deviation of MMO for Group A was 3.69 ± 0.5 cm and for Group B was 4.46 ± 0.4 cm. Statistically significant difference was found using Mann-Whitney U-test with U = 239.500 and = 0.0001. Pearson's coefficient = -0.623 and = 0.0001 showed moderate correlation between months of chewing and MMO. The mean duration of chewing was found to be 1.5 years.
There is difference in MMO between children chewing areca nut and not chewing it with a moderate correlation between months of eating areca nut and MMO.
槟榔通常单独咀嚼或与各种香料混合咀嚼。在亚洲许多地区，包括印度，嚼槟榔的行为很普遍。使用者常常认为嚼槟榔无害，并表示会有愉悦感，但有证据表明嚼槟榔远非无害，会对口腔健康产生多种影响，比如导致口腔黏膜下纤维化，造成张口困难以及引发癌变。印度的研究报告称，这种习惯在学龄儿童中的患病率呈上升趋势。本研究的目的是探究嚼槟榔对张口度的影响，将其与没有此习惯的儿童进行比较，并找出最大张口度（MMO）与嚼槟榔月数之间的相关性。
本研究旨在探究在艾哈迈达巴德的学龄儿童中嚼槟榔对最大张口度的影响。
在艾哈迈达巴德的多所学校开展了一项观察性分析研究。
本研究共纳入80名12至14岁的男学生。A组包括有嚼槟榔习惯6个月及以上的儿童，B组为没有嚼槟榔习惯的儿童。刚开始嚼槟榔不到6个月的儿童被排除在研究之外。使用校准纤维尺测量最大张口度，即从上门牙边缘到下门牙边缘的距离。
采用SPSS 20.0软件进行统计分析，显著性水平设定为5%。
A组最大张口度的均值和标准差为3.69±0.5厘米，B组为4.46±0.4厘米。使用曼-惠特尼U检验发现存在统计学显著差异，U = 239.500，P = 0.0001。皮尔逊系数r = -0.623，P = 0.0001，表明嚼槟榔月数与最大张口度之间存在中度相关性。嚼槟榔的平均时长为1.5年。
嚼槟榔的儿童与不嚼槟榔的儿童在最大张口度上存在差异，且嚼槟榔月数与最大张口度之间存在中度相关性。
