Abstract

Dental caries during infantile and early childhood period is a complex disease resulting from multiple caries factors. Streptococcus mutans(S. mutans) plays a critical role in the initiation of caries, and its early transmission through mothers provides a strong etiologic factor for future development of caries in the primary dentition. Therefore, early detection of caries risk factor is important for prevention of caries. Recent studies about etiologic factors of caries have brought advent of various tools for caries risk assessment in order to predict progress of caries more accurately. Cariogram is a common tool for caries risk assessment, which illustrates present caries risk assessment and correlation of caries risk factors for an individual graphically. The aim of this study was to assess if there is any correlation in the level of S. mutans and caries activity and to verify the effect of caries risk factors between children with age ranging from 3 to 5 years with severe early childhood caries(S-ECC) and their mothers using caries-related salivary test and Cariogram. The results of this study were as follows. 1. Children with S-ECC had a statistically higher level of Streptococcus mutans compared to caries-free children(p<0.05). 2. There was significant correlation between mothers and their children in the aspect of the level of Streptococcus mutans(p<0.05). 3. When caries activity was assessed using Cariogram, significant correlation between mothers and their children was found(p<0.05). 4. When each caries risk factor was evaluated for its affect on caries activity, host was more influential factor compared to microorganism and diet in children. Based on these results, we could conclude that assessing the level of S. mutans can be an effective tool for predicting possibility of caries formation in future. Since prediction of future caries progression and evaluation of caries risk factor became possible with Cariogram, we may conduct early and preventive measures for treatment of caries.

영유아기 치아우식증은 복잡하고 다인자적 질환으로 숙주 및 미생물, 식이, 시간 등의 위험요소에 의해 질환이 진행된다. 이 중 미생물로 대변되는 Streptococcus mutans(S. mutans)는 우식 개시에 있어 중요한 역할을 하며, 어머니를 통한 수직 감염이 잘 알려져 있다. 영유아기의 어머니를 통한 조기 감염은 향후 유치열기 우식 발생과 높은 연관성을 나타내므로 우식위험요소에 대한 조기 파악은 미래의 치아우식증 예방에 있어 매우 중요하다. 최근 치아우식증의 원인 및 이에 미치는 요소들에 대한 연구가 활발하게 이루어지면서 우식 진행에 대한 정확한 예측을 위한 여러 가지 우식위험도평가(caries risk assessment) 도구가 개발되었는데, 이 중 대표적인 한 가지가 Cariogram이다. Cariogram은 개인의 우식활성도 및 우식위험요소(caries risk factor)의 상호작용을 그래프로 나타낸다. 이번 연구의 목적은 3${\sim}$5세의 중증 유아기우식증(Severe Early Childhood Caries; S-ECC)에 해당되는 어린이들과 그들의 어머니 사이에서 우식관련타액검사 및 최근 개발된 Cariogram을 이용하여 S. mutans의 수준 및 우식활성도에 대한 상관관계가 존재함과 우식위험요소 간의 연관성을 파악해 보았는데, 이를 통해 다음과 같은 결론을 얻을 수 있었다. 1. 중증 유아기우식증을 보이는 어린이에서 구강 내 존재하는 Streptococcus mutans의 수준은 비우식군보다 높았다(p<0.05). 2. 모자간 구강 내 존재하는 Streptococcus mutans 수준은 상관관계를 보였다(p<0.05). 3. 모자간 우식활성도를 Cariogram을 통해 측정해 본 결과 상관관계를 보였다(p<0.05). 4. 우식활성도에 미치는 우식위험요소는 어린이에서 숙주요소가 가장 큰 영향을 주는 것으로 나타났다. 이상의 결과로 S. mutans가 향후 치아우식증 발생 가능성을 예측하는데 있어 유용한 우식위험요소가 될 수 있으며, Cariogram을 통한 향후의 우식진행과 관련된 여러 가지 우식위험요소가 예측 가능하므로 이에 대한 조기 대처 및 예방적 처치가 가능하리라 사료된다.
