关于青少年口腔PH值变化规律的研究
|
摘要
目的:研究青少年口腔PH值变化规律。方法:从菏泽家政职业学院随机选取50名青少年学生,作为受试者。对所选学生每天18个时间点的口腔PH值进行监测并记录一周,并分析研究青少年学生口腔PH值变化规律。结果:采用t检验对不同时间点的口腔PH均值进行分组统计分析,p<0.05表示差异有统计学意义,统计结果显示:早餐前、中午10点、临睡前的口腔PH均值高于起床立即的口腔PH均值,p<0.05,有统计学意义;早餐后立即口腔PH均值高于早餐后5分钟口腔PH均值,p<0.05,有统计学意义;早餐后10分钟口腔PH均值高于早餐后15分钟口腔PH均值,p<0.05,有统计学意义;而早餐前口腔PH均值与中午10点口腔PH均值的比较,p=0.21,p>0.05,没有统计学意义。结论:通过对学生一天18个点的口腔PH值监测一周并记录数据作图结果显示:在"起床立即"时处于最低值,三餐的"餐后立即"时口腔PH均值处于最高值,三餐的"餐后5分钟、10分钟、15分钟"口腔均PH值逐渐降低,临睡前的口腔PH值稍微升高。
Objective: To study the changes of oral PH in adolescents. Methods: 50 students randomly selected from HZ Domestic Professional College as the research objects. The oral PH of the subjects at 18 time points was monitored and recorded for one week. The changes of oral pH in adolescent students were analyzed. Results: The t-test was used to analyze the average oral PH value at different time points, p<0.05 means the difference was statistically significant. The statistical results showed that the oral PH mean before bedtime was higher than before bedtime at 10 o'clock before breakfast The average PH value of oral cavity, p<0.05, was statistically significant. The average PH value of oral cavity immediately after breakfast was higher than the average oral PH value at 5 minutes after breakfast, p <0.05, with statistical significance; the oral PH value ten minutes after breakfast was higher than that after breakfast the average oral PH mean, p <0.05, statistically significant; while before breakfast, oral PH mean and 10 o'clock noon oral PH mean comparison, p = 0.21, p> 0.05, no statistical significance. Conclusion: By monitoring the oral pH of students for 18 points a day for one week and recording the data, the results showed that the average oral pH was the highest at the lowest value of‘get up immediately' and‘immediate after meal' of three meals, 5 minutes postprandial, 10 minutes, 15 minutes' the average oral pH value decreased gradually before going to sleep oral p H value increased slightly.
