Bad breath causes embarrassment and affects interpersonal social communication. Morning breath odor is a commonly encountered oral problem which should be rectified with effective oral hygiene measure.
The aim of this study was to assess and compare the effectiveness of different oral hygiene regimens on the reduction of morning bad breath, plaque formation, and gingivitis in healthy young adults.
A four-step, crossover clinical trial was conducted among 40 young adults aged 18-22 years residing in one of the nongovernmental organizations in New Delhi.
Study participants were divided into four groups, which underwent intervention for 7 days each. Group 1: tooth brushing; Group 2: tooth brushing and mouthwashing; Group 3: tooth brushing and tongue scraping; and Group 4: combination of all. A washout interval of 14 days was employed in between the groups. Breath scores were measured at three time intervals whereas oral health status was recorded at the beginning and the end of each interventional period.
Appropriate tests such as paired t-test, ANOVA test, and Pearson correlation tests were used in the study.
The highest reduction in mean value of breath scores (2.03 ± 0.69) was found in Group 4 followed by Group 3. Similarly, Group 4 showed the highest reduction in mean value of plaque score (0.79 ± 0.19) and gingival score (0.54 ± 0.23) followed by Group 2.
Combination of mechanical and chemical oral hygiene measures is an effective regimen for the reduction of morning bad breath.
口臭会导致尴尬并影响人际社交沟通。晨起口臭是常见的口腔问题，应通过有效的口腔卫生措施加以纠正。
本研究旨在评估和比较不同口腔卫生方案对健康年轻成年人晨起口臭减轻、牙菌斑形成和牙龈炎的效果。
在新德里一家非政府组织居住的40名18 - 22岁年轻成年人中进行了一项四步交叉临床试验。
研究参与者分为四组，每组接受7天的干预。第1组：刷牙；第2组：刷牙和漱口；第3组：刷牙和刮舌；第4组：所有措施联合使用。组间采用14天的洗脱期。在三个时间间隔测量口气分数，而在每个干预期开始和结束时记录口腔健康状况。
研究中使用了配对t检验、方差分析和皮尔逊相关检验等适当的检验方法。
第4组口气分数平均值降低最多（2.03±0.69），其次是第3组。同样，第4组牙菌斑分数平均值降低最多（0.79±0.19），牙龈分数平均值降低最多（0.54±0.23），其次是第2组。
机械和化学口腔卫生措施联合使用是减轻晨起口臭的有效方案。
