초록
유아용 시럽형 약물은 어린이가 쉽게 복용할 수 있도록 여러 종류의 당분을 감미제로 사용하고 있으며 그로 인한 우식의 위험이 높다고 할 수 있다. 그러나 시럽형 약물의 우식유발성에 대한 보호자의 인지도는 매우 낮으며 의료 종사자들조차 이를 소홀히 여기고 있어 문제의 심각성이 크다고 할 수 있다. 본 연구는 시럽형 약물이 구강 내 산도에 미치는 영향에 대하여 조사할 목적으로, 15 종의 시럽형 약물의 산도를 조사하고, 그 중 널리 시판되는 4종을 선택하여 이 약물들이 치태의 산도 변화에 미치는 영향을 평가하였다. 또한 가장 흔하게 사용하는 유아용 시럽형 약물의 일종인 코푸시럽의 복용방법에 따른 타액의 산도 변화를 측정하여 다음과 같은 결과를 얻었다. 1. 15 종 시럽형 약물의 산도는 pH 3.0.6.8의 범위에서 다양하여 평균 pH 4.7±0.94로 나타났다. 2. 치태의 산도변화를 측정하기 위해 선정된 4종의 시럽형 약물 모두는 구강 내 투입 직 후 법랑질의 탈회 임계점인 pH 5.5 이하로 치태의 산도를 급격히 떨어뜨렸으며, 시간 경과에 따른 치태의 산도 변화에서 콜디(종합 감기약)를 제외한 모든 약물에서는 유의한 차이가 없었다(p>0.05). 3. 코푸 시럽으로 구강을 헹구어낸 경우와 코푸 시럽에 이어 물로 구강을 헹구어낸 경우 타액의 산도 변화에 있어서는 유의한 차이가 있었다(p<0.05).
Abstract
Syrup form medicines which children commonly take contains sugar as sweeteners. Sugar, low endogenous pH, high acidity, mucosity and low concentrations of ions including those of calcium, fluoride, and phosphate in their composition, they can be cause of caries and erosion. Not only the properties found in such medicines, but also other factors such as high frequency of ingestion, bedtime consumption, and the collateral effect of a reduction in salivary flow, poor oral hygiene of sick children may also contribute to the risk. The other side, parents rarely recognize these risk, and medical experts also easily overlook. The purpose of this study was to investigate the pH level of some syrup form medicines which are frequently administered by infants and young children, and their effects on the changes of plaque pH when rinsing with them. And we compared the salivary pH change induced by rinsing with Cough-syrup only and rinsing with Cough-syrup followed by water. The results were as follows : 1. The average pH of syrup form medicines which were prescribed in Pusan National University Hospital and several OTC syrup form medicines was pH 4.7±0.94, within the range of pH 3.0 to 6.8. 2. The plaque pH decreased rapidly below pH 5.5 after rinsing with the syrup form medicines which were selected for the test and there was no statistically significant difference in the of plaque pH change between syrup form medicines except COLDI(p>0.05). 3. There was statistically significant difference in salivary pH change between rinsing with Coughsyrup only and rinsing with water after Cough-syrup(p<0.05).
