「ATPの検出を利用した口腔内の衛生状態の判定に関する研究(第1報)」では, 唾液のATPふき取り法で口腔内の衛生状態を判定できる可能性を示唆した. 今回の研究目的は, 歯磨き後のうがいの効果を水道水150mlでうがい(ブクブクうがいとガラガラうがいの併用)を3回, 生食150mlでうがいを2回行い, その前後の口腔内の衛生状態を評価し, 明らかにすることである. 唾液の平均ATP量は, 歯磨き前の値と比較すると1回目のうがいで水道水が4.12倍, 生食が2.98倍であり, 2回目のうがいでは, 水道水, 生食ともに歯磨き前の唾液のATP量に近づき, 水道水3回目では歯磨き前より低くなっていて有意差が認められた. 生食単独うがいでは有意差が認められなかったが, 1回目でATP量が高値になり2回目ではうがい前より低くなっていた. このことから, 歯磨きによって唾液はいったん汚れるが, うがいの容量を300ml以上にすると口腔内に残留した汚れを取り除くことが可能と考えられた.
In a previous study, we have suggested that the salivary ATP swab test provides a simple and valid method to establish oral hygiene. (The assessment of oral hygiene with the ATP detection test : A comparative study of tooth brushing and garglerelated variation using the salivary ATP swab test) The purpose of the current study is to assess oral hygiene before and after tooth-brushing followed by either rinsing and gargling three times with 150 mL tap water or twice with 150 mL saline. Saliva ATP values were 4.12 and 2.98 times higher than the baseline after first rinsing and gargling with tap water and saline, respectively. In addition, after second rinsing and gargling either with tap water or saline, the ATP values were close to those of the saliva before tooth-brushing. Moreover, after third rinsing and gargling with tap water, the ATP value was lower prior to tooth-brushing. Significant difference was found in comparing the mean ATP values in saliva. First rinsing and gargling with saline increased ATP values, whereas, the second rinsing and gargling decreased ATP values to below the pre-rinsing baseline, although the difference was not statistically significant. Thus, the saliva was contaminated by tooth-brushing, however, it was considered possible that rinsing off with more than 300 mL liquid can remove debris stagnant in the oral cavity.
