Objectives : This study assessed the development of caries in preschool children over two years according to baseline caries pattern. Methods : Connecticut Head Start children (n=142, mean age=3.8 years) were examined for dental caries at baseline (spring 1991) and once annually for two years. Children were categorized at baseline as caries-free, having pit and fissure (PF) caries, or having maxillary anterior (MA) caries. Results : After two years, children who presented at baseline with MA or PF caries had a mean posterior dmfs of greater than seven and four times, respectively, that of children who were caries-free at baseline. When dental caries of the primary dentition was categorized by specific posterior patterns (i.e., posterior proximal [PPJ] and buccal/lingual [BL]), change in dmfs for the PP and BL patterns in the group that presented with pit/fissure caries at baseline were nearly four and three times greater, respectively, than for those in the caries-free group. The group that presented with maxillary anterior caries at baseline had PP and BL caries increments eight times those of children who began caries-free. Conclusion : Dental caries presentation in 3- to 4-year-old children can identify those children and tooth surfaces that will be at the greatest risk for future caries development. 相似文献

Recent Dental Caries and Treatment Patterns in US Children 总被引:1,自引:0,他引:1

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. 相似文献

ObjectiveThe aim of this study was to examine the satisfaction of parents and caregivers of patients who underwent dental treatment in general anesthesia (GA) in a day-care surgery setting.Material and MethodsAnonymous questionnaire was sent to parents/caregivers of patients who underwent full mouth restoration in GA. The survey consisted of 4 parts: general data, data about procedure, satisfaction with various aspects of care and the perception of parents/caregivers about the condition of their child in relation to the time before dental treatment in GA.Results66 parents/caregivers (30.5%) responded to the questionnaire. Overall satisfaction with the treatment was high (4.69). Respondents expressed the highest degree of satisfaction with communication with nurses (4.92), and the lowest with the waiting time for the procedure (3.89). Parents/caregivers of patients who reported difficulty eating expressed significantly lower overall satisfaction than the subjects whose children did not report difficulty eating. Also, the more treatments the patients underwent, the lower was the overall satisfaction than of those subjects whose children were never treated in such a manner before.ConclusionsSince patient satisfaction has a beneficial impact on treatment outcome and adherence to preventive recommendations, all health care providers should strive to achieve it. 相似文献

ObjectiveThis study aimed to reveal the geographic accessibility of dental clinics for most municipalities in Japan in 2015 and to explore the association between dental accessibility and dental caries status in 3-year-old children.MethodsWe computed the accessibility index and accessibility index rate for the population outside a 1-km radius of dental clinics using a geographic information system. We also used spatial autocorrelation analysis (Moran's I statistic) to examine the spatial clustering patterns of dental accessibility in Japanese municipalities. In addition, we adjusted the prevalence of dental caries for most municipalities using empirical Bayesian estimation. Finally, we applied multiple linear regression to scrutinise the associations between dental caries status, including the prevalence of dental caries and decayed and filled teeth (dft), and dental accessibility, with adjustments made for other sociodemographic variables.ResultsThe distribution of dental accessibility in Japanese municipalities is relatively unequal. Dental accessibility is decent in the 3 metropolitan areas around Tokyo, Osaka, and Nagoya but poor in the Tohoku and Kyushu regions. In addition, dental accessibility is significantly related to the prevalence of dental caries and dft after adjusting for other sociodemographic variables (P < .005).ConclusionsThis study suggests that dental accessibility is considerably connected to the dental caries status of 3-year-old children after excluding financial burden. Preschool children in areas with poor dental accessibility are likely to have poor dental caries status. We also verified the inequality of dental accessibility amongst Japanese municipalities. For the future development of primary oral health care, more attention should be paid to people with a disadvantage in terms of dental accessibility. 相似文献

Objective:To longitudinally investigate the caries risk levels in children undergoing orthodontic treatment with sectional brackets.Materials and Methods:A total of 42 children scheduled for orthodontic treatment with sectional orthodontic appliances participated in this study. They were divided into two groups based on decayed, missing, and filled permanent and deciduous teeth (DMFT/dmft) scores and counts of mutans streptococci (MS) prior to treatment. One was the low caries risk group (n = 26) and the other was the high caries risk group (n = 16). Paraffin-stimulated whole saliva was collected for examination of salivary flow rate, buffer capacity, and MS and lactobacilli (LB) levels before treatment, 2 and 4 months after appliance placement, and 2, 4, and 8 months after appliance removal.Results:The pretreatment salivary flow rates, buffer capacity, and MS levels remained statistically unchanged during and after active orthodontic treatment in both groups. The levels of LB in the high caries risk group were significantly elevated by appliance placement, but upon appliance removal started to fall significantly and came a little short of the pretreatment levels. In the low caries risk group, the pretreatment levels of LB remained statistically unchanged during and after treatment. There were no significant differences in salivary flow rate or buffer capacity, but there were significant differences in MS and LB scores between the two groups at every measurement time.Conclusions:In children undergoing orthodontic treatment with sectional brackets, LB levels are an important part in making caries risk assessment. 相似文献
