Recent dental caries and treatment patterns in US children

Abstract

This report presents dental caries and treatment patterns found in a longitudinal study of US children between 1978 and 1982 who were geographically dispersed across several fluoridated and nonfluoridated sites. The analyses include first- and fifth-grade children examined annually for four years in the National Preventive Dentistry Demonstration Program and who did not receive effective preventive procedures. The results indicate that in association with the caries decline in US children, treatment ratios increased by over 20 percent during the study period. FS/DFS ratios averaged 79 percent for the four grade/fluoridation status cohorts analyzed and were significantly higher in fluoridated than in nonfluoridated sites. The single-fissured surface was the dominant treatment or disease area observed and these surfaces tended to be restored early. In assessing tooth-surface status changes annually, tooth surfaces were more than twice as likely to change from sound to filled than from sound to decayed between yearly examinations at fluoridated sites. The lower levels of decay and higher degree of restorative care observed were not observed in lower SES and black children nearly to the extent as those for higher SES and white children in the population. The dental profession should shift its emphasis from the early restoration of fissured-surface defects to an expanded use of sealants for those with reduced decay and focus resources on a minority of the population with high caries levels who receive limited care.
