Oral health status of New Hampshire Head Start children, 2007-2008

Ludmila Anderson MD
Abstract Objectives: We report on the baseline prevalence and severity of dental caries of children enrolled in the New Hampshire Head Start program during the 2007-2008 school year. Methods: We selected a random cluster sample of 607 children aged 3-5 years attending 27 Head Start centers across the state. Four volunteer dentists provided oral examinations and determined the presence of untreated dental caries, caries experience, and treatment urgency. Results: Overall, 40 percent of the participating children had experienced dental caries, and 31 percent had at least one untreated decayed tooth. Approximately 22 percent of the children had evidence of maxillary anterior caries, 23 percent were in need of dental care, and <1 percent needed urgent care. Conclusions: The prevalence of dental caries is comparable with that reported by Head Start programs elsewhere. The prevalence of caries affecting maxillary anterior teeth is higher. Further studies should examine state-specific barriers to dental care among this population. [source]

Specific Caries Index: A New System for Describing Untreated Dental Caries Experience in Developing Countries

Shashidhar Acharya MDS
Abstract Objectives:To develop a reproducible surface-specific caries index that provided qualitative and quantitative information about untreated dental caries, that could be used in conjunction with the DMFS index and would provide information on not only the caries prevalence but also the location and type of caries lesion in an individual based on clinical examination. Methods:Untreated carious lesions were divided into six types based on the location of the lesions.339 rural school children in the age group of 12,15 years were examined for dental caries using both the DMFS index and the Specific Caries Index. Results:Type 1 and 2 were found to be the most common type of caries lesions. The reproducibility of the Specific Caries Index was also found to be good. Conclusions:Encouraging indications about the validity and reproducibility of this new caries index was found, suggesting the need for further studies to test its applicability in larger and different populations.

Dental Caries Status and Need for Dental Treatment of Pennsylvania Public School Children in Grades 1,3, 9, and 11

Robert J. Weyant DMD
ABSTRACT Objectives: This cross-sectional study was designed to determine the caries status and provide a general evaluation of the level of dental treatment need of Pennsylvania public school children in grades 1, 3, 9, and 11 on a statewide and regional basis. Methods: Between September 1998 and May 2000, caries status and treatment need were assessed using a school-based dental examination, performed on a representative sample (n=6,040) of public school children in grades 1, 3, 9, and 11 (age range=6 to 21 years). Children's caries status in the primary and permanent dentition was assessed. Need for treatment was scored on a three-level categorical scale,no treatment need identified, routine treatment need, and urgent treatment need,and was based on the presence and severity of caries and other oral conditions. Population estimates of the prevalence of untreated dental caries, DMFT and dft scores, and treatment need were calculated by grade and geographically, using the six Pennsylvania health districts and the cities of Pittsburgh and Philadelphia. The inequality of caries distribution in the population was assessed for both permanent and primary caries using Lorenz curves and Gini coefficients. Results: Dental caries has remained highly prevalent among Pennsylvania's public school children. Caries levels varied considerably by health districts and city. Urgent treatment needs were significant and also varied by health district and city. Conclusions: Dental caries remains the most prevalent disease affecting Pennsylvania's schoolchildren. Caries status varies significantly by region of the state, suggesting that environmental, social, and demographic contextual factors may be important determinants of disease prevalence. [source]

Assessing the effectiveness of a school-based oral health promotion programme in Yichang City, China

Bao-Jun Tai
Abstract,,, Objectives:, To assess the outcome of oral health promotion in schoolchildren over a 3-year period in Yichang City, Hubei, China. Methods:, In a cluster randomized controlled trial, the concept of the World Health Organization Health Promoting Schools Project was applied to primary schoolchildren. Seven intervention schools and eight control schools were randomly selected from one district by stratified cluster sampling. The study was conducted as a 3-year follow-up study. After 3 years, 661 children remained in the intervention group and 697 children in the control group. Data on dental caries, plaque accumulation, and sulcus bleeding were collected by clinical examination, while behavioural data were gathered by self-administered questionnaires. Results:, The 3-year net mean DMFS increment score was 0.22 in the intervention schools and 0.35 in the control schools (P < 0.013). A statistically significant difference in mean plaque (P < 0.013) and sulcus bleeding (P < 0.005) increment scores after 3 years was found between the two groups. Statistically significant higher scores were observed in restorations received and sealants placed, and a lower score in untreated dental caries, in children from the intervention group than the control group after 3 years (P < 0.01). In addition, more children in the intervention schools adopted regular oral health behavioural practices such as brushing their teeth at least twice a day, visiting the dentist within the past calendar year, and using fluoride toothpaste. Conclusion:, The study suggests that the school-based oral health promotion was an effective way to reduce new caries incidence, improve oral hygiene and establish positive oral health behavioural practices in the targeted schoolchildren.
