The process and outcome of a programme for preventing early childhood caries in Thailand

OBJECTIVE: To evaluate the process and outcomes of a participatory dental health education (DHE) programme for preventing early childhood caries (ECC). DESIGN: A one-year intervention programme. SETTING: 21 health centres. PARTICIPANTS: 520 mothers/caregivers of 6-19 month-old children who lived in a rural area of Thailand. INTERVENTION: Small group discussion with active involvement in the intervention group and the national teaching DHE programme in the control group. MAIN OUTCOME MEASURES: Health centre staff impact evaluation, children's dental cavitated carious increment and stated changes in oral health behaviour. RESULTS: After one-year, the percent of subjects using a toothbrush and tooth brushing with fluoride toothpaste was 93% and 87% respectively in the intervention group, significantly higher (p<0.01) than the control group (73% and 58% respectively). Night time bottle-feeding, falling asleep with a bottle and sweet snack diet behaviour appeared the same in both groups. The net cavitated carious increment was 3.5 (SD=3.4) teeth in the intervention and 3.2(SD=3.5) in the control group. Health centre staff were very supportive of the programme and suggested extending the participatory format to other child health topics. CONCLUSIONS: The participatory dental health education model was shown to be a practical and effective method for increasing oral hygiene practice, but was not sufficient to prevent the development of ECC. This single intervention in the short term is not seen as sufficient to prevent the development of ECC.     

Determinants of early childhood caries in low-income African American young children

PURPOSE: The aim of this longitudinal study was to evaluate the association between early childhood caries (ECC) and severe ECC (S-ECC) and social, dietary, and behavioral risk factors. METHODS: A representative sample of low-income 0- to 5-year-old children was selected from Detroit. Children and their caregivers were examined for the presence and severity of dental caries. Trained interviewers administered questionnaires assessing social, dietary, and behavioral factors. RESULTS: A total of 1,021 child and caregiver dyads were examined in wave 1. Of these, 788 (77%) were re-examined in wave 2. ECC and S-ECC were highly prevalent in this cohort By 2 years of age, 7% of the children had ECC without S-ECC (ECC-only) and 27% had S-ECC. The regression model found that age of the child and caregiver, child's gender, and caregivers' fatalistic oral health beliefs were significantly associated with higher odds ratios of developing ECC-only and S-ECC. Consumption of soda beverages was associated with developing S-ECC. Religiosity was protective against ECC-and S-ECC. CONCLUSIONS: Early childhood caries and severe early childhood caries are highly prevalent in low-income African American children. Intake of soda beverages by the children and the caregivers' fatalistic oral health beliefs and religiosity were significant determinants of ECC and S-ECC.

Identifying risk factors for predicting caries in school-aged children using dental health information collected at preschool age

The study was done to identify toddlers who have an increased risk of developing dental decay at school age. Six variables-Cariostat score, mother's ethnicity, evidence of baby bottle tooth decay, mother;s dental health status, toddler's age at first tooth, and frequency of brushing - showed a significant association with decay status at school age with odds ratios ranging from 1.89 to 2.63. The Cariostat score and the frequency of brushing remained significant in a logistic regression. No interaction terms were significant. The Cariostat caries activity test would be a useful screening tool for identifying toddlers most likely to develop decay or could be used periodically as the deciduous molars erupt and become colonized with oral bacteria. The findings confirm that good oral hygiene practices can have an impact on future dental health, and caregivers should be encouraged to brush young children's teeth regularly.     

Early childhood caries in children aged 6-19 months

OBJECTIVES: To investigate the relationship between socioeconomic factors, behaviors and the severity of early childhood caries (ECC) in 6-19 month-old Thai children. The severity of ECC was estimated using the proportion of ECC teeth to erupted teeth. This was termed the 'Intensity of ECC' (I-ECC) index. METHODS: Cross-sectional questionnaire survey, dental examinations, and mutans streptococci counts were obtained from children and mothers/caregivers who participated in the ECC prevention program. RESULTS: The 520 children from rural areas were categorized into four age groups by the mean number of erupted teeth. In the 15-19-month-old children, the prevalence of ECC was 82.8% (cavitated caries, 40.8%; noncavitated caries, 42.0%) with a mean ECC teeth score of 4.18 +/- 3.19. The mean I-ECC severity score was 0.45 +/- 0.30 in these toddlers. Children from low-income families, those with low education, and mothers/caregivers with decayed teeth had higher I-ECC scores (P < 0.05). Children who were breast fed or had high counts of mutans streptococci also had higher I-ECC scores (P < 0.05). The logistic regression model revealed that only children's mutans streptococci level was a statistically significant predictor of ECC, with an odds ratio = 4.5 (95% CI = 1.8, 11.7). CONCLUSIONS: ECC is not only a public health problem but also a social problem in Thailand, because it relates to family income and education level. The community development approach to assisting disadvantaged Thai children should be combined with an effective preventive program at a very young age. Future longitudinal research should be performed to improve the I-ECC for measuring the severity of ECC.     

Oral health disparities in children of immigrants: dental caries experience at enrollment and during follow-up in the New England Children's Amalgam Trial

OBJECTIVES: Previous research shows increased dental decay among immigrants, but little is known about the oral health of the growing population of children of immigrants. We compared the children of immigrants to the children of US-born caregivers in their caries experience at enrollment and their new caries increments during the 5-year New England Children's Amalgam Trial (NECAT). METHODS: NECAT recruited 283 Boston-area children aged 6 to 10 with untreated caries and offered free semiannual preventive and restorative dental care during the trial. Sociodemographic factors and caregiver immigrant status were assessed through interviews. Multivariate negative binomial models evaluated the association between caregiver immigrant status and clinically assessed carious surfaces. RESULTS: Forty percent of these Boston-area children had immigrant caregivers. At baseline, the children of immigrants had more carious surfaces (11.5 versus 9.4, adjusted for race/ethnicity, age, gender, and caregiver smoking status). Caregiver language preference explained some of this association. Immigrant status and language preference were not associated with 5-year caries increments. CONCLUSIONS: Prevalent disparities in the unmet dental needs of the immigrants' children were quickly ameliorated during participation in NECAT Dental initiatives that target neighborhoods and are sensitive to acculturation levels may help improve and maintain the oral health of immigrant families.     

Caries prevalence and bottle-feeding practices in 2-year-old children with cleft lip, cleft palate, or both in Taiwan.

OBJECTIVE: The purposes of this study were to investigate the caries prevalence in cleft lip, cleft palate, or both in children under the age of 2 years and to evaluate parental attitudes toward bottle-feeding, dental care, and their relationship to baby bottle tooth decay (BBTD) in Taiwan. DESIGN: Randomized and prospective study. SETTING: Institutional setting. PATIENTS AND METHODS: One hundred twenty-three 2-year-old children (68 boys and 55 girls) with cleft lip, cleft palate, or both were selected for this study. A questionnaire that asked questions about knowledge of oral health, knowledge and beliefs about BBTD, children's feeding habits, children's dental care, and parenting attitudes toward children with clefts was completed by the parents or caretakers. Children were divided into bottle-feeding and non-bottle-feeding groups according to the questionnaire responses of parents or caretakers. Each child was examined with a dental mirror and explorer under focused flashlight using defs index to determine the presence of BBTD. RESULTS: Thirty-nine percent (48) subjects reported a bottle-feeding habit; the overall prevalence of BBTD was 15.4%. The habit of bottle-feeding was significantly related to BBTD (p = .019). The defs score for children who were bottle-fed was significantly higher than children who were not bottle-fed (p = .045). Parents or caretakers of both bottle-feeding and non-bottle-feeding children showed no significant differences in their attitudes toward bottle-feeding and feeding habits (p > .05). However, parents of non-bottle-fed children had significantly better dental care than parents of bottle-fed children in brushing frequency (p < .001) and brushing before bed (p < .001). CONCLUSIONS: Children with clefts who took a bottle to bed showed an increased risk of developing BBTD. The parents or caretakers of bottle-fed children also showed a lack of motivation to perform regular preventive dental home care for their children. This suggests that oral health promotion programs should begin in infancy for children with clefts and their parents.     

Prevalence of early childhood caries in a population of children with history of maltreatment

OBJECTIVE: The purpose of this study was to investigate the prevalence of early childhood caries (ECC) in a population of maltreated children in Toronto, Ontario, Canada. METHODS: The sample consisted of preschool-aged children (2 to 6 years) admitted to the care of the Children's Aid Society of Toronto (CAST) between 1991 and 2004. Data were collected by reviewing the dental and social workers' records of CAST ECC was determined using the decayed, missing, and filled deciduous teeth (dmft) index. The type and severity of maltreatment were obtained from the Eligibility Spectrum. RESULTS: The study included 66 children: 37 (56 percent) boys and 29 (44 percent) girls, with an average age of 4.1 years [standard deviation (SD) = 1.2]. Four (6 percent) children had evidence of dental injury, and none had teeth filled or extracted as a result of decay ECC was observed in 58 percent of the abused children. Of these, the mean decayed teeth ("dt") value was 5.63 (SD = 4.17, n = 38) and 3.24 (SD= 4.21) for the whole sample (n = 66). The proportion of children with untreated caries was 57 percent among "neglected" children (n = 53) and 62 percent in physically/sexually abused cases (n = 13). Logistic regression revealed that children in permanent CAST care and those in its care more than once were significantly less likely to have experienced caries. CONCLUSIONS: Abused and neglected young children had higher levels of tooth decay than the general population of 5-year-olds in Toronto (30 percent prevalence, mean dt= 0.42, SD = 1.20, n = 3185). However, this study did not find any difference in ECC prevalence between children with different types of maltreatment. The study did find that CAST services had a protective effect on children's oral health, which supports the recommendation that child protection services should investigate possible dental neglect in physical/sexual abuse and neglect cases.     

Early childhood caries and quality of life: child and parent perspectives

PURPOSE: The purpose of this study was to investigate the effects of early childhood caries (ECC) on children's oral health-related quality of life (QOL) before and 4 weeks after its treatment, as assessed by the children themselves as well as by their parents/guardians. METHODS: This study had a longitudinal intervention design. Sixty-nine children diagnosed with ECC and 43 children without caries (combined children's mean age=50.4 months; range=22 to 70 months) and their parents/guardians responded to face-to-face administered surveys before a dental treatment was started (baseline assessment). Thirty-seven children with ECC completed dental rehabilitation. Four weeks after the treatment was completed, these 37 children as well as their parents/guardians responded to a second survey (follow-up assessment). RESULTS: The results show that children with ECC have significantly lower oral health-related QOL than children without ECC as assessed both by the children and the parents/guardians at baseline. The children with ECC who received dental treatment had a significantly improved oral health-related QOL at the follow-up assessment when compared with their baseline measurement as measured both with the children's self-ratings of oral health-related QOL and the parents'/guardians' perception of their child's oral health-related QOL. CONCLUSIONS: ECC and its treatment affect children's oral health-related QOL in a significant way. Oral health-related QOL can be assessed validly and reliably both in self-reports from children as young as 36 months of age as well as by asking parents/guardians about their perceptions of their child's oral health-related QOL.     

The relationship between healthful eating practices and dental caries in children aged 2-5 years in the United States, 1988-1994

BACKGROUND: As a result of the introduction of multiple fluoride vehicles and other preventive agents, caries prevalence rates in young children have been declining over the past two decades in the United States. However, changing dietary patterns in young children may offset some of the oral health benefits of fluoridation. The objective of this study was to examine the relationship between caries in primary teeth and healthful eating practices in young children. METHODS: The authors used data from the third National Health and Nutrition Examination Survey to investigate the relationship between healthful eating practices (such as breast-feeding, eating breakfast and consuming five servings of fruits and vegetables a day) and dental caries (untreated tooth decay and overall caries experience) in the primary dentition among children aged 2 through 5 years. RESULTS: The odds of experiencing caries in primary teeth were significantly greater in nonpoor children who did not eat breakfast daily or ate fewer than five servings of fruit and vegetables per day (odds ratio, or OR = 3.77; 95 percent confidence interval, or CI, 1.80 to 7.89 and OR = 3.21; 95 percent CI, 1.74 to 5.95, respectively). No association was found between breast-feeding and caries in primary teeth. CONCLUSION: Young children with poor eating habits are more likely to experience caries. Overall, the findings support the notion that dental health education should encourage parents, primary caregivers and policy-makers to promote healthful eating practices, such as eating breakfast daily, for young children. PRACTICE IMPLICATIONS: Dental professionals are well-positioned to inform parents and caregivers regarding age-appropriate healthful eating practices for young children entrusted in their care.     

维生素D水平与低龄儿童龋风险的相关性分析

目的探讨维生素D水平与低龄儿童龋(early childhood caries,ECC)发生风险的相关性分析,为ECC儿童的一级预防提供依据。方法收集389名6~48月龄儿童的月龄、喂养方式、口腔健康行为等资料,记录龋、失、补指数(decayed?missing?filled teeth,dmft),分为ECC组(n=146)和无龋组(n=243),采集指尖末梢血检测维生素D体内活性形式--25?羟维生素D[25(OH)D],采集牙菌斑行龋活跃性检验检测龋态(Cariostat)值,Logistic回归分析25(OH)D等龋相关因素与ECC发生风险的相关性。结果25(OH)D缺乏、不足、正常的儿童的患龋率差异无统计学意义(c2=2.320,P=0.313)。dmft与25(OH)D水平之间无相关(dmft=1~3,r<0.001,P>0.05;dmft>3,r=0.009,P>0.05)。而月龄(OR=1.082,95%CI:1.045~1.121,P<0.001)、出生后6个月内母乳喂养(OR=2.789,95%CI:1.581~4.921,P<0.001)、吃夜奶或含乳头睡(OR=4.187,95%CI:1.938~9.048,P<0.001)、1.5~3.0的高Cariostat值(OR=4.173,95%CI:2.014~8.646,P<0.001)是ECC的风险因素。结论25(OH)D水平与6~48月龄儿童龋无相关性,而月龄、出生后6个月内母乳喂养、吃夜奶或含乳头睡、高龋活跃性(Cariostat值1.5~3.0)是ECC的风险因素,提倡母乳喂养的同时,应为幼儿树立良好的喂养习惯及口腔卫生习惯。     

Parental perceptions of their preschool-aged children's oral health

BACKGROUND: Parents have an important role in making decisions about their children's oral health. The purpose of the authors' study was to determine parental perceptions of their children's oral health status and factors correlated with these perceptions of health. METHODS: The authors analyzed data for 3,424 children (2-5 years of age) from the Third National Health and Nutrition Examination Survey. They based the dependent variable on a question asked of primary caregivers: "How would you describe the condition of [child's name]'s natural teeth?" Explanatory variables included demographic variables, dental visits, perception of child's general health, need for dental care and presence of tooth caries. RESULTS: Eighty-nine percent of parents rated their child's oral health as excellent, very good or good, and 11 percent rated it as fair or poor (mean = 2.7 on a five-point scale, with 1 being excellent and 5 being poor). Tooth caries, perceived need for dental cleaning and treatment, lower income and poorer general health perceptions were associated with poorer parental ratings. CONCLUSIONS: Actual disease and perceived need are associated significantly with parents' perceptions of their children's oral health. PRACTICE IMPLICATIONS: Understanding parents' perceptions of their children's oral health and factors that motivate these perceptions can help dentistry overcome barriers that parents encounter in accessing dental care for their children.     

Planning and implementation of community oral health programs for caries management in children

Tooth decay or cavities (dental caries) can have a significant impact on children's quality of life, causing pain, infection, and other problems in the oral environment. Good oral health is a fundamental element of good general health for children, yet dental caries is still prevalent among children in many countries. Dental caries is well-understood, and effective prevention is an attainable goal. Dental professionals should actively engage with communities--in particular, the underprivileged--to identify dental caries problems and implement appropriate and effective community oral health programs (COHPs) to improve oral health and reduce oral health inequalities. This paper discusses COHPs as well as the steps involved in caries prevention for children. These steps cannot ensure the success of every COHP, but they are helpful for developing, integrating, expanding, and enhancing them. The effectiveness of COHPs for the prevention of caries in children varies from country to country, according to cultural, social, economic, and health care settings. Careful consideration of the local situation is required when selecting the elements of COHPs.

Factors Influencing Early Childhood Caries of Cleft Lip and/or Palate Children Aged 18 to 36 Months in Southern Thailand

Objective: To clarify whether oral health care behavior or oral cleft status influences early childhood caries in southern Thailand cleft children. Design: A comparative cross-sectional study. Patients, Participants: A total of 138 southern Thai children aged 18 to 36 months comprised two groups of 69 participants, one with cleft lip and/or palate and controls with no cleft. Methods: All children were examined for early childhood caries by using the severity (DMFT/tooth) index. A structured interview was conducted among caregivers, and then multiple regression analysis was applied. Results: Children with oral clefts had a larger number of early childhood caries (ECC) and poorer feeding habits than those without. From a structured questionnaire, the caregivers of children with clefts exercised poorer oral health behavior than those of the controls, but the cleft status was not an important factor for caries prevalence when oral health behaviors were controlled. Multivariate analysis showed that sweetened bottled milk consumption, night-time feeding habit, and frequent sugary food consumption were the variables significantly associated with dental caries. Conclusions: Children with oral clefts in southern Thailand had greater caries experience when compared with noncleft subjects. However, cleft status was not significant for ECC, and night-time feeding habit was the most important factor for higher ECC in children with clefts.     

Reliability and validity of brief measures of oral health-related knowledge, fatalism, and self-efficacy in mothers of African American children

PURPOSE: Low-income African American children experience high rates of dental caries compared to the general population. Knowledgeable and efficacious caregivers can play an important role in caries prevention. The purpose of this study was to develop and evaluate 4 brief measures reflecting mothers' potentially modifiable cognitions associated with African American children's oral health: (1) knowledge about appropriate bottle use (KBU); (2) knowledge about children's oral hygiene (KCOH); (3) oral health-related fatalism (OHF); and (4) oral health-related self-efficacy (OHSE). METHODS: Questions were selected based on reviews of the health promotion and oral health literature, with input from low-income African American caregivers of young children. Reliability and validity were evaluated using survey and dental examination data from 719 low-income African American mothers and their 1- to 5-year-old children. RESULTS: Alpha reliabilities ranged from 0.76 to 0.91. KCOH was significantly associated with mothers' oral health perceptions and children's caries status. OHSE was significantly positively correlated with children's brushing frequency and with mothers' subjective perceptions of children's oral health, which was, in turn, significantly associated with children's caries status. CONCLUSIONS: Results support the reliability and validity of the new measures. If confirmed by further research, these measures can be used to develop tailored educational and cognitive-behavioral interventions to reduce oral health disparities.     

Oral health-related quality of life and early childhood caries among preschool children in Trinidad

Background

Early childhood caries (ECC) is a public health problem in developed and developing countries. The purpose of this study was to describe the relationship between oral health-related quality of life (OHRQoL) and ECC among preschool children in a Caribbean population.

Method

Parents/primary caregivers of children attending nine, randomly selected preschools in central Trinidad were invited to complete an oral health questionnaire and have their child undertake an oral examination. The questionnaire included the Early Childhood Oral Health Impact Scale (ECOHIS). Visible caries experience was assessed using WHO criteria. Logistic regression models were used to determine the factors associated with OHRQoL and ECC.

Results

Three hundred nine parents/caregivers participated in the study (age-range 25–44 years) and 251 children (mean age 3.7 years) completed oral examinations. Adjusting for other factors, the odds for a child aged 4 years of having dental caries were greater than the odds for a child aged 3 years (OR 3.61; 95% CI (1.76, 6.83). The odds for children having difficulty drinking hot or cold drinks were greater for those with dental caries than the odds for children who have no such difficulty. Similarly, the odds for children who had difficulty eating were greater for those with dental caries than the odds ratios for children who had no difficulty eating (OR 8.29; 95% CI (2.00, 43.49). Adjusting for the effects of other factors, the odds of parents/caregivers feeling guilty were greater if their child had experienced dental caries in comparison to parents/caregivers whose child did not have dental caries (OR 3.50; 95% CI (1.32, 9.60). Adjusting for other factors, the odds of parents/primary caregivers having poor quality of life was increased when they had a child with a dmft in the range 1–3 (OR 2.68; 95% CI (1.30, 5.64) dmft?>?4 (OR 8.58; 95%CI (3.71, 22.45), in comparison to those whose child had a dmft?=?0.

Conclusion

In this sample of preschool children OHRQoL was associated with ECC. More negative impacts were found in children with a greater severity of visible caries experience. This suggests the need for strategies to prevent and manage ECC in this Caribbean population.

     

Models for coronal caries and root fragments in an elderly population.

A random sample of 809 dentate, home-dwelling people 65 years of age or older participated in a study to determine the prevalence of dental diseases in the elderly. Part of the study investigated the determinants of coronal caries and root fragments in these older adults. Using a wide array of potentially explanatory variables available, logistic regression models were developed to identify relationships between these variables and coronal caries and root fragments. The variables with the most explanatory power in the coronal caries model were the presence of decayed root surfaces, lower salivary flow rate, lack of regular dental care and an interaction variable including race and a perception of financial well-being. When a subsequent model was created that did not include decayed root surfaces or root fragments as potential explanatory variables, an additional variable relating to self-perception of mouth appearance emerged. The strongest variables in the model for root fragments were episodic (vs. regular) dental visits, presence of root caries, lack of replacement for lost teeth, high levels of Streptococcus mutans and number of teeth present in the mouth.     

Dental caries status of preschool children in Hong Kong

OBJECTIVE: To describe the dental caries status of preschool children in Hong Kong and factors which affect their caries status. DESIGN: 658 preschool children aged 4 to 6 years from six randomly selected kindergartens in Hong Kong were surveyed in December 1997. A questionnaire to investigate possible explanatory variables for caries status was completed by their parents. Dental caries was diagnosed according to the criteria recommended by the World Health Organization (1997). RESULT: Caries experience as measured by the mean number of decayed, missing and filled primary teeth (dmft) of the 4-, 5-, and 6-year-old children were found to be 0.9, 1.8, and 3.3 respectively. Overall, 61% of the children had a zero dmft score. Children born in Mainland China had a higher mean dmft score (4.6) than those born in Hong Kong (1.4). Statistically significant correlations were found between the children's dental caries status and their oral health practices as well as their socio-economic background. Parents' education level, dental knowledge and attitudes were also associated with the children's dental caries experience. CONCLUSION: In general, the caries status of Hong Kong Chinese preschool children was similar to that of children in industrialised countries and was better than that of children in the nearby areas. However, special dental programmes should be made available to children from lower socio-economic classes and new immigrants from Mainland China because they are the high risk groups for caries in Hong Kong.     

Biological mechanisms of early childhood caries

The present paper reviews biological issues in early childhood caries (ECC) in light of the current understanding of the field. Despite the general global decline in dental caries in the past decades, ECC has become a significant problem in many developing countries and some minority communities in western industrialized nations. Like other types of caries, ECC is caused by mutans streptococci that ferment dietary carbohydrates to produce acid attacks on susceptible teeth over a period of time. However, while the general etiology of ECC appears similar to that of other types of caries, the predisposing factors are still unclear. The biology of ECC may be modified by several factors unique to young children, related to the implantation of cariogenic bacteria, immaturity of the host defense systems, as well as behavioral patterns associated with feeding and oral hygiene in early childhood.
