The objective of the present study was to investigate among children in the initial mixed dentition phase the presence of clinical signs that might eventually function as more sensitive indicators of the development of caries disease, denoted here as caries activity. On this basis, we investigated the relationship between salivary levels of mutans streptococci (MS) and decayed, missing and filled permanent and deciduous tooth surfaces (DMFS and dmfs) using microbiological, clinical and radiographic examinations in 81 schoolchildren aged 7-8 years. Whereas dmfs did not present a positive correlation, DMFS was significantly correlated with salivary MS levels. The first permanent molars of the schoolchildren studied comprised 87.3% of the affected surfaces recorded in the DMFS, suggesting that the development of new lesions was preferentially located on the surfaces of the first permanent molars. These results permit us to conclude that the first permanent molars function as first indicators of dental caries activity in the schoolchildren examined.
本研究的目的是在儿童混合牙列初期阶段，调查可能最终作为龋病发展更敏感指标（在此称为龋活性）的临床体征。在此基础上，我们通过微生物学、临床和影像学检查，对81名7 - 8岁学童的变形链球菌（MS）唾液水平与恒牙和乳牙龋失补牙面数（DMFS和dmfs）之间的关系进行了研究。虽然dmfs未呈现正相关，但DMFS与唾液MS水平显著相关。所研究学童的第一恒磨牙占DMFS记录的患龋面的87.3%，这表明新病变的发展优先位于第一恒磨牙表面。这些结果使我们能够得出结论，在所检查的学童中，第一恒磨牙是龋病活动的首要指标。
