The diagnosis of early carious lesions is essential for nonsurgical management of dental caries. This report describes the prevalence of early noncavitated and cavitated carious lesions in the primary dentition of 5-year-old Head Start schoolchildren in Alachua, Fla.
As part of the Fluoride Varnish Study conducted at the University of Florida, modified caries diagnostic criteria-which differentiated caries lesion activity and severity-were developed for the primary teeth. Dental examinations were conducted on 221 children ages 5 years by 2 calibrated examiners.
Overall, 86% of the children had experienced noncavitated or cavitated caries lesions in the primary dentition. Prevalence of cavitated dentinal lesions was 48%, and prevalence of active noncavitated enamel lesions was 71%. The mean number of active noncavitated enamel lesions (mean +/- SEM: 2.91 +/- 0.21) was slightly higher than the mean number of cavitated dentinal lesions (2.52 +/- 0.31). The mean number of restored surfaces was 1.24 (+/- 0.42), and only 8% of the children had 1 or more restored surfaces. Noncavitated lesions were most common on occlusal surfaces, especially in mandibular second molars. African-American children had a higher prevalence of noncavitated lesions (81%) than whites (69%) or others (33%; P<.0001). Prevalence of cavitated lesions was 49% for African Americans, 46% for whites, and 48% for others.
This study shows that noncavitated enamel and cavitated dentinal lesions are common in this study population's primary dentition. There is a need for preventive measures and treatment of decay in these children living in low-income families.
早期龋损的诊断对于龋病的非手术治疗至关重要。本报告描述了佛罗里达州阿拉楚阿市5岁开端计划学龄前儿童乳牙列中早期非龋洞型和龋洞型龋损的患病率。
作为佛罗里达大学进行的氟化物涂膜研究的一部分，针对乳牙制定了改良的龋病诊断标准，该标准可区分龋损的活动度和严重程度。由2名经过校准的检查者对221名5岁儿童进行口腔检查。
总体而言，86%的儿童乳牙列中出现了非龋洞型或龋洞型龋损。龋洞型牙本质病变的患病率为48%，活动性非龋洞型釉质病变的患病率为71%。活动性非龋洞型釉质病变的平均数量（均值±标准误：2.91±0.21）略高于龋洞型牙本质病变的平均数量（2.52±0.31）。修复面的平均数量为1.24（±0.42），只有8%的儿童有1个或更多修复面。非龋洞型病变最常见于咬合面，尤其是下颌第二磨牙。非裔美国儿童非龋洞型病变的患病率（81%）高于白人（69%）或其他种族（33%；P<0.0）。非裔美国人龋洞型病变的患病率为49%，白人为46%，其他种族为48%。
本研究表明，在该研究人群的乳牙列中，非龋洞型釉质病变和龋洞型牙本质病变很常见。有必要对这些低收入家庭儿童采取预防措施并治疗龋齿。
