中文摘要 | 經常攝取飲料和高齲齒率有關,本實驗係以臺灣四種常用飲料漱口,來評估對人類牙菌斑酸鹼值之影響。10位受試者經洗牙後,48小時不刷牙以堆積牙菌斑,再以銻電極測量上顎第一大臼齒近心側之牙菌斑酸鹼值。 測量時間分別為漱飲料前、其後5分、15分、30分、45分及60分鐘。四種飲料為碳酸飲料、乳酸菌飲料,運動飲料及芭樂汁;分別間隔兩週測試一次。測量數據包括起始牙菌斑酸鹼值、最大酸鹼值下降量、最低酸鹼值、降至最低酸鹼值所需時間、回復所需時間、及60分鐘內酸鹼值變化曲線與起始酸鹼值所含蓋的區域面積。測量數據以Wilcoxon signed rank test分析,比較四種飲料間之差異。實驗結果顯示:四種飲料漱口後都會使牙菌斑酸鹼值降低,其中以碳酸飲料牙菌斑酸鹼值下降量最大,芭樂汁的牙菌斑酸鹼值下降量最小,且回復時間最快;四種飲料的致酸性強弱順序為碳酸飲料、乳酸菌飲料、運動飲料及芭樂汁。本研究的結論為此四種飲料經牙菌斑酸鹼值測試,均呈現大致類似的致酸性,經常飲用應注意可能造成齲齒。 |
英文摘要 | A high incidence of dental caries associated with frequent consumption of soft drinks has been reported. The purpose of this study was to evaluate the pH response of dental plaque to four popular soft drinks in Taiwan. Ten volunteers participated and accumulated dental plaque for 48 hours. Plaque pH was measured at the mesial surface of the maxillary first molar with an antimony electrode. Plaque pH was measured before and 5, 15, 30, 45, and 60 minutes after rinsing with test drinks for one minute. Four soft drinks (carbonate, lactate, sports drink and guava juice) were tested separately at two week intervals. Baseline resting pH, maximum pH drop, minimum pH, time to minimum pH, recovery time of pH to baseline value, and curve area under the resting pH were measured and analyzed. The Wilcoxon signed rank sum test was used for comparison. All the test drinks had the ability to lower the plaque pH below the prerinse resting plaque pH. Only lactate lowered plaque pH below the critical value of 5.5. Carbonate drink resulted in the greatest pH drop, while guava juice ahd the least pH drop and earliest return from the minimum pH to baseline, in 45 min. The ranking order of the acidogenicity (Σ D) of test drinks was carbonate, lactate, sport drinks and guava juice. Conclusion: The sugar-containing beverages in our study had similar acidogenicities, and therefore may play a role in the development of dental caries with frequent use. |
