The prevalence of dental caries in primary dentition in 4- to 5-year-old preschool children in northern palestine

Examining the Role of Vitamin D in Caries Susceptibility in Children's Deciduous Teeth: A Systematic Review

The global prevalence of dental caries in deciduous teeth remains a significant health concern, affecting almost 70% of children by the age of six in specific regions. This systematic review aspired to methodically investigate the association between vitamin D levels and susceptibility to caries in children's deciduous teeth. A detailed search, guided by the PRISMA and PROSPERO guidelines, was conducted across three prominent electronic databases: PubMed, Web of Science, and Scopus, culminating in August 2023. The search integrated various keywords related to vitamin D and dental caries in primary dentition, yielding an initial pool of 1678 articles. After meticulous scrutiny, seven studies with a total of 7655 participants were deemed suitable for inclusion. The studies represented diverse geographical regions, showcasing varied vitamin D levels and sun exposure. Patient habits like brushing frequency, dental visits, and vitamin consumption also varied across studies. The analysis pinpointed vitamin D deficiency as a potential risk factor in some of the studies, with Odds Ratios (OR) ranging from 0.68 to 2.15. Statistically significant associations between vitamin D deficiency and caries susceptibility were documented in three studies (ORs of 2.15, 1.98, and 1.70). This comprehensive review elucidates the complex relationship between vitamin D levels and dental caries in children's deciduous teeth. While some studies spotlight vitamin D's pivotal role in dental health, inconsistencies across studies and regional differences necessitate more in-depth, globally representative investigations. Ensuring optimal vitamin D levels may play an integral role in dental health strategies. However, it is important to highlight that the roles of these studied factors might differ in deciduous teeth compared to permanent teeth.

An Assessment of the Prevalence of Dental Caries, Oral Hygiene Status, Deft Index, and Oral Hygiene Habits Among Children With Special Healthcare Needs

Background and objective Children with special healthcare needs are at an increased risk of oral health problems, including dental caries. Understanding the prevalence of dental caries, oral hygiene status, deft (decayed, extracted, filled teeth) index, and oral hygiene habits in this population is crucial for effective oral healthcare planning and interventions. The aim of this study was to assess the prevalence of dental caries, oral hygiene status, deft index, and oral hygiene habits among children aged 4-15 years with special healthcare needs in Jodhpur District, Rajasthan, India. Methods A cross-sectional study was conducted among 124 children from various, government and non-governmental organizations (NGO)-run special schools. Data on dental caries, oral hygiene status, deft index, and oral hygiene habits were collected using standardized tools and techniques. Descriptive statistics, including frequencies and percentages, were used to analyze the data. Results The prevalence of dental caries among children with special healthcare needs was 65%. The severity of dental caries varied, with 40% classified as mild, 20% as moderate, and 5% as severe. Additionally, 75% of the children exhibited poor oral hygiene, as indicated by the oral hygiene status assessment. The mean deft index score was 2.8, indicating an average dental caries experience among the participants. Regarding oral hygiene habits, 60% reported brushing their teeth once a day, while 40% reported brushing twice a day. However, a significant proportion (70%) reported non-fluoride use, and 55% stated they did not perform regular flossing. Conclusion This study highlights a high prevalence of dental caries, poor oral hygiene status, and suboptimal oral hygiene habits among children with special healthcare needs in Jodhpur District. The findings emphasize the need for targeted interventions focusing on preventive measures, oral health education, and improving access to oral healthcare for this vulnerable population. Further research with larger sample sizes and longitudinal study designs is warranted to validate these findings and develop effective strategies for enhancing oral health outcomes in children with special healthcare needs.

Behavioral and social determinants of early childhood caries among Palestinian preschoolers in Jerusalem area: a cross-sectional study

BACKGROUND

This study came to determine the prevalence of Early Childhood Carries (ECC) among preschoolers in a marginalized population and describe the influence of behavioral and social determinants on the development of ECC.

METHODS

This is a cross-sectional study that was carried out in four random preschools in the Jerusalem Governorate of the Occupied Palestinian Territories. All children aged 3-5 years old in the selected schools were screened for ECC using the decayed, missing, and filled teeth index (dmft). Data on children's socio-economic, feeding habits, hygiene habits, access to care, parental level of stress, social support, and locus of control were collected by a validated questionnaire sent to the children's main caregivers. Descriptive statistics were generated and bivariable and multivariable analyses were used to explain the influence of different behavioral and social determinants on ECC levels.

RESULTS

Four hundred and fifty-seven preschoolers completed the questionnaire and the clinical screening. Ninety-seven percent (n = 447) had experienced dental decay, with an average dmft score of 6.6 ± 4.3. After accounting for potential confounding, parents' internal locus of control was associated with lower dental caries among children (IRR = 0.97, 95% CI = 0.97, 0.98). Having routine, preventive visits versus never seeing a dentist were associated with lower dmft scores (IRR = 0.42, 95% CI = 0.33, 0.52). Night feeding habits (putting things other than water in the baby bottle at night, having children sleep while being breastfed at night) were positively associated with children's dental caries (IRR = 1.06, 95% CI = 1.04, 1.09: IRR = 1.15, 95% CI = 1.03, 1.29, respectively). Not adding sugar to the bottle was negatively associated with children's dental caries (IRR = 0.86, 95% CI = 0.74, 1.00).

CONCLUSIONS

Preschoolers in this study suffered from high dental caries experience. Although infant feeding habits were key factors in explaining the elevated level of the disease, system and socio-psychological factors were also detrimental to ECC prevalence. Policies and interventions to alleviate the burden of ECC need to address socioeconomic determinants of health in addition to feeding and hygiene practices.

Pediatricians' Knowledge of Children's Oral Health: A National Survey

BACKGROUND

A high percentage of dental caries (∼70%) was reported amongst 4- and 5-year-old Kuwaiti kindergarten children. Parents contact paediatricians several times during the child's early life. Paediatricians can play an important role in improving the oral health of their patients. The objective of the study is to evaluate the knowledge level and awareness of paediatricians and paediatric residents regarding children's oral health in Kuwait.

METHODS

A national cross-sectional survey was distributed to paediatricians and paediatric residents practicing in Kuwait. Data concerning demographic variables, knowledge on dental caries preventive measures, current anticipatory guidance, and experience with dental problems and oral care were collected using online and paper-based surveys.

RESULTS

A total of 230 participants completed the survey, with a response rate of 50.1%. Most respondents (81%) had frequently noticed dental caries in children in their practice. Two-thirds of respondents felt confident in detecting dental caries. However, more than two-thirds were unfamiliar with preventive dental practices and the management of dental trauma. Only 16.5% of the respondents got a satisfactory knowledge score on the preventive measure questions, and nearly 51% had satisfactory knowledge on the recent anticipatory guidance questions. No significant correlations were found between gender or years of practice and knowledge scores. Respondents' confidence in detecting caries was significantly associated with the knowledge score of the anticipatory guidance (P = .003). Fewer than half of the respondents considered prescribing sugar-free syrup (47.4%) and counselled patients regarding the use of mouthguards during sports for schoolchildren (39%).

CONCLUSIONS

The majority of paediatricians have adequate knowledge of the current anticipatory guidance of oral health issues, but they have insufficient knowledge of oral preventative measures and dental trauma. Adequate education and training in oral health are highly recommended.

Prevalence of Dental Caries in Children in Mymensingh and Its Associated Risk Factors: A Cross-Sectional Study

Background: Children suffer from various oral and periodontal diseases. Dental caries is one of the most prevalent oral diseases among children in the world. This study was conducted to identify the prevalence and risk factors of dental caries in children in Mymensingh, Bangladesh. Methods: A cross-sectional study was conducted on 362 pediatric patients who attended the Dental Unit of Mymensingh Medical College from March to September 2019. The sample size was calculated using a statistical formula and the children were selected using a systematic random sampling technique. Children and their guardians were interviewed and data were recorded using a structured questionnaire. Risk factors were analyzed using multivariate logistic regression. Results: The overall prevalence of dental caries was 82.7%. The prevalence of caries was significantly higher in aged children (8–10 years) and also in rural, low-income, and illiterate families. Seven significant risk factors were identified that included residence in the rural area (OR: 7.31 [1.73–30.83]), a parental income of BDT ≤ 20,000 per month (OR: 4.75 [1.49–15.05]), reduced duration (≤1 min) of teeth cleaning (OR: 18.54 [2.05–168.17]), teeth cleaning before breakfast (OR: 93.30 [10.95–795.32]), the spoon-feeding method (OR: 12.57 [2.09–75.61]), long-term (37–48 months) breastfeeding (OR: 212.53 [8.69–5195.25]), and family oral problem (OR: 8.20 [2.57–26.16]). Conclusions: The prevalence of dental caries among the children in Mymensingh is very high and was associated with residence in rural areas, parental income, reduced duration of teeth cleaning, teeth cleaning before breakfast, the spoon-feeding method, long-term breastfeeding, and family oral problems.

Oral Health Knowledge and Experience of Pediatricians and Pediatric Residents in Kuwait: A Nationwide Cross-Sectional Survey Study

Objective

To evaluate the knowledge level and practice of pediatricians and pediatric residents regarding children's oral health in Kuwait. Subjects and Methods. A nationwide cross-sectional survey was distributed to pediatricians and pediatric residents practicing in Kuwait. Data concerning demographic variables, knowledge on dental caries preventive measures, current anticipatory guidance, and experience with dental problems and oral care were collected using online and paper-based surveys.

Results

A total of 230 completed the survey with a response rate of 50.1%. Most respondents (81%) had noticed dental caries in children more frequently. Two-thirds of respondents felt confident in detecting dental caries. However, more than two-thirds were unfamiliar with preventive dental practices and the management of dental trauma. Only 16.5% of the respondents got satisfactory knowledge score on the preventive measures questions, and nearly 51% got satisfactory knowledge on the recent anticipatory guidance questions. No significant correlations were found between gender or years of practice and knowledge scores. Respondents' confidence in detecting caries was significantly associated with the knowledge score of the anticipatory guidance (p=0.003).

Conclusion

Dental caries is an oral problem commonly encountered by many pediatricians and pediatric residents in Kuwait. The majority has adequate knowledge of the current anticipatory guidance of oral health issues, but they have insufficient knowledge levels on oral preventative measures. Adequate education and training in oral health are highly recommended.

Mother’s Characteristics and Socioeconomic Status as Possible Risk Factors for Children’s Caries in Jordan

Background. Clinical oral health status of children affects their health-related quality of life. A major determinant of oral health is early childhood caries, which possesses a negative effect. Objective. The primary objective of the study was to examine the association between socioeconomic status and different mother’s characteristics and the risk of dental caries in children using the decay missing filled (DMF) score as an indicator. Methods. This was a cross-sectional descriptive study that was in the pediatric dental clinic in Hashem Ibn Al-Hussein medical military hospital in Jordan. Pearson correlation was used to examine associations between two continuous variables. Linear regression was used to detect variables that might predict the decayed missing filled teeth (dmft) score of the child. Results. A total of 264 children were enrolled in the study. Average age of children was 4.80 ± 1.99 years, and average mothers’ age was 32.74 ± 5.68. Mothers had an average DMFT score of 8.84 ± 5.39, while children had an average dmft score of 6.17 ± 4.82. There was no association between the mother’s age and the dmft score of the child (Pearson correlation = 0.08, and $P$ value = 0.215). However, a moderate, statistically significant correlation was found between the mother’s and the child’s DMFT scores (Pearson correlation = 0.418, and $P$ value = 0.001). Children who belonged to low and middle-income families had a higher dmft score compared to those that belonged to families with high income. Conclusion. Socioeconomic status of the family, mother’s habits, dental hygiene, and education level are important factors that influence the child’s oral health. Strategies that focus on children with these characteristics can help them achieve better oral health.

Prevalence of Early Childhood Caries among the 3–5-year-old Children in Jeddah, Saudi Arabia

Introduction

Dental caries is a significant dental public health issue and it is the world's most common oral health condition among children. In the Kingdom, the prevalence and severity of early childhood caries has been rising.

Aim

The aim of the study is to establish the prevalence of early childhood caries among children aged 3-5 years in Jeddah as well as the associated risk factor of visiting a dentist.

Methodology

The research is based on a cross-sectional observational design. Children from both private and public schools were randomly selected from schools in all of Jeddah's regions until a sufficient sample size was attained. For the diagnosis of early childhood caries, the American Academy of Pediatric Dentistry criteria were used.

Results

In Jeddah, the prevalence of early childhood caries is 57% among children aged 3-5 years.

Conclusion

Caries in young children is a public health issue. There should be an increased emphasis to the parents that the child should visit the dentist by 12 months of age as recommended by many professional organizations. Regular dental appointments would then help to lessen the caries burden on children at an early age. The Four A's treatment regimen is recommended to aid in the prevention and early detection of early childhood caries.

Determinants of dental caries in children in the Middle East and North Africa region: a systematic review based on literature published from 2000 to 2019

Background

Dental caries risk factors have been expanded to not only emphasize biology, dietary and oral habits but also broader social determinants such as socioeconomic factors and the utilization of health services. The aim was to review sociobehavioural/cultural and socioeconomic determinants of dental caries in children residing in the Middle East and North Africa (MENA) region.

Methods

A search was conducted in the PubMed/Medline database and Google Scholar to identify studies published from 2000 to 2019 covering children using key search terms. In the initial stages, titles, abstracts and, if needed, full articles were screened for eligibility. In the final stage, all included articles were reassessed and read, and relevant data were extracted.

Results

Out of 600 initial articles, a total of 77 were included in this review, of which 74 were cross-sectional, 2 were longitudinal and one was a case–control study. The studies included a total of 94,491 participants in 14 countries across the MENA region. A majority used the World Health Organization scoring system to assess dental caries. The caries prevalence ranged between 17.2% and 88.8%, early childhood caries between 3% and 57% and decayed missing filled teeth (dmft) varied between 0.6 and 8.5 across the various age groups. Increased age, low maternal education, low overall socioeconomic status, decreased frequency of tooth brushing, low parental involvement, poor oral habits, infant feeding practices and sugar consumption were among the most prevalent determinants for increased risk of caries in the reviewed studies.

Conclusions

Dental caries was found to be high among children in many of the studies published from MENA. The key determinants of dental caries were found to include factors related to child characteristics, family background, oral hygiene and infant feeding and eating habits. The high dental caries prevalence emphasises the need to address the prevailing modifiable sociobehavioural and socioeconomic determinants by translating them into effective oral health prevention policies and programmes.

Workforce and Contents of Home Dental Care in Japanese Insurance System

Background

In Japan's super-aging society, it is required to establish a home dental service provision system. It is necessary to analyze the current state of visiting dentistry.

Methods

A cross-sectional survey was conducted using a self-administered postal mail questionnaire distributed to all members of the Iwate Dental Association. We analyzed the implementation status of dental care at home/nursing facilities, the number of dental clinic staff, and the contents of dental home care. Correspondence analysis, item response theory, and zero-inflated model were used for the analysis.

Results

Of the 354 dental clinics, 187 (52.8%) performed visiting dental care and 195 (55.1%) implemented dental care in a nursing home. Visit dentistry was mainly performed by part-time workers. Denture treatment and oral care were common treatments for dental home care.

Conclusion

More than half of the dental clinics did not offer visiting dentistry. In order to fully provide dental visiting services, infrastructure development is necessary. Specifically, human resources are most important, even if they are part-time workers.

The Prevalence of Dental Caries in Primary Dentition in 3- to 5-Year-Old Preschool Children in Northern China

Objectives

To investigate the prevalence and factors promoting caries in primary dentition of 3-5-year-old children in Northeast China.

Materials and Methods

Data of 1,229 children aged 3 to 5 years were randomly selected. The caries prevalence and other indicators were assessed, and the results analyzed by SPSS. A questionnaire was also given to the children's guardians to ascertain the potential risk factors associated with caries.

Results

The decayed, missing, and filled teeth (dmft) index in children aged 3, 4, and 5 years old was 3.17, 5.13, and 6.07, respectively, while the caries prevalence rate was 62.16%, 75.89%, and 87.28% accordingly. The incidence of caries among rural children was higher than that in urban areas. Regarding oral health awareness, it was found that parents in urban areas had more accurate perceptions of oral health problems. It was also noted that the children's brushing habits were worrying. Family economic and medical resources are not the main causes of serious dental caries in rural areas.

Conclusions

The oral health status of children aged 3-5 years is not optimistic. Many parents have a low awareness of oral health. Strengthening the promotion of oral health knowledge is an effective way to change the situation.

Early childhood caries and infant's oral health; pediatricians' and family physicians' practice, knowledge and attitude in Riyadh city, Saudi Arabia

Background

Early childhood caries (ECC) is a significant worldwide oral health problem. However, parents do not take their children to the dentist for regular screening of oral diseases as early as they do with pediatricians and family physicians. As a result, pediatricians and family physicians are considered as a reliable and perfect source for children's oral health promotion and disease prevention. Studies assessing pediatricians' and family physicians' practice, knowledge and attitude regarding ECC and infant's oral health in Saudi Arabia are few. As a result, this study aimed to assess these aspects.

Methodology

A cross-sectional study based on a structured close-ended questionnaire was conveniently distributed among pediatricians and family physicians in Riyadh city, Saudi Arabia. The questionnaire composed of two main sections; demographic characteristics and questions assessing participants' practice, knowledge and attitude. The data was analyzed using SAS software, frequency and chi-square test were conducted, and P-value of <0.05 and less was considered significant.

Results

There was a discrepancy between the participants' knowledge, attitude and practice. The participants' practice was lower (42.6%) compared with their attitude (86.1%) and knowledge (65.3%). Most of the participants (52.5%) indicated lack of clinical time was the main barrier for performing oral health related activities. Majority of the participants (76.7%) indicated that they need more dental training and education. Dental caries preventive methods (44.6%) was the most requested topic, of which workshops and seminars were the main preferred method (39.6%).

Conclusion

Although most of the participants reported good dental attitude and knowledge, a lack of the associated dental practice was detected. Therefore, more efforts are encouraged to enhance and facilitate dental practice among pediatricians and family physicians.

Caries Experience and Oral Health-related Factors of Kuwaiti Preschool Children and their Mothers: A Pilot Study

Aim

The objective of this study was to investigate the association between the caries experience and oral-health-related behavior of Kuwaiti preschool children and their mothers.

Materials and methods

A convenience sample of 84 participants (42 child-mother pairs) was selected. Data regarding children's and mothers' demographics, oral hygiene practices, and dietary habits were obtained by questionnaires. Oral clinical examinations were carried out on the participant children and mothers to determine their caries experience (decayed, missing, and filled teeth index-dmft/DMFT).

Results

An estimated 19% of children were caries-free and 66% of mothers have untreated caries. The mean dmft index of the preschool children was 3.90 ± 2.9, and the mean DMFT index of their mothers was 12.38 ± 5.4. Mothers' untreated caries was significantly associated with their children's untreated caries (r = 0.183, p < 0.05). No correlation was found between the brushing frequencies of children and their mothers (p = 0.582). High consumption of sugary snacks and sugary beverages was detected among the children and mothers with a significant association (p < 0.05). The mean dmft of the children was found to be significantly lower among the young mothers, less than 30 years, (2.4 ± 2.1) compared to that among the mothers older than 30 years (4.3 ± 2.9, p < 0.05).

Conclusion

There was a high prevalence of early childhood caries in the preschool children studied. A positive correlation was found between the dental caries experience and sugar consumption of the Kuwaiti preschool children and those of their mothers.

Clinical significance

The oral health status and dietary habits of mothers are potentially significant risk factors for the development of early childhood caries in their children. Pediatric dentists need to identify the main caries risk factors in their community in order to implement appropriate preventive dental care and educational programs.

Early Childhood Caries

Early childhood caries (ECC) is a common childhood disease with highest prevalence found in poor, socially disadvantaged, and minority groups. The main risk factors for ECC are frequent sugar consumption, lack of tooth brushing, and enamel hypoplasia. Contributory factors include environmental and psychosocial stresses that modify caregiver behaviors. Strategies for prevention include preventing mutans streptococci transmission, restricting dietary sugars, tooth brushing, topical fluoride applications, and early dental examinations. This article provides an overview of ECC based on current understanding of its cause, prevention, and management.

Caries status in young Colombian children expressed by the ICCMS™ visual/radiographic combined caries staging system

OBJECTIVE

To report (1) the caries experience prevalence and mean, and the caries severity and distribution patterns, expressed clinically and combined with radiographs with the conventional and ICCMS™ systems in young children from Bogotá, Colombia; (2) the contribution of including radiographs to the clinical caries scoring and (3) in which surfaces the radiograph adds to the clinical caries registration.

MATERIAL AND METHODS

Six hundred children from kindergartens/schools were enrolled: Cohort A: 2-year (n = 200), Cohort B: 4-year (n = 200) and Cohort C: 6-year (n = 200) olds. Radiographs were taken of the 4- and 6- year olds. Children were examined clinically using the Clinical (C) and Radiographic (R) ICCMS™-epi Caries Scoring Systems, staging caries lesions (d) as: Initial (C_epi/R_A), Moderate (C_M/R_B) or Extensive (C_E/R_C). Caries experience including missing (m) and filled (f) surfaces was expressed as follows: clinical conventional (Cd_MEmfs); clinical ICCMS™ (Cd_epiMEmfs); combined conventional (C + Rd_MEmfs) and combined ICCMS™ (C + Rd_epiMEmfs).

RESULTS

The prevalence of Cd_MEmfs was: Cohort A: 32%; Cohort B: 59%; Cohort C: 67.5%, increasing to 73.5%, 99.8% and 100%, respectively, with the C + R d_epiMEmfs. The Cd_MEmfs means doubled when initial caries lesions (Cd_epi) and radiographs (R) were included. The d component corresponded to over two-thirds of the caries experience. Findings on the radiographs significantly raised caries experience prevalence and means (p < .02), detecting primarily approximal lesions. Surfaces with highest caries frequency were occlusal/approximal of molar teeth and buccal of upper incisor teeth.

CONCLUSION

Participants' caries experience was high. The radiographic assessment significantly contributed to caries experience. Molar and upper incisor teeth were most prone to caries.

Early Childhood Caries: Prevalence, Risk Factors, and Prevention

Early childhood caries (ECC) is major oral health problem, mainly in socially disadvantaged populations. ECC affects infants and preschool children worldwide. The prevalence of ECC differs according to the group examined, and a prevalence of up to 85% has been reported for disadvantaged groups. ECC is the presence of one or more decayed, missing, or filled primary teeth in children aged 71 months (5 years) or younger. It begins with white-spot lesions in the upper primary incisors along the margin of the gingiva. If the disease continues, caries can progress, leading to complete destruction of the crown. The main risk factors in the development of ECC can be categorized as microbiological, dietary, and environmental risk factors. Even though it is largely a preventable condition, ECC remains one of the most common childhood diseases. The major contributing factors for the for the high prevalence of ECC are improper feeding practices, familial socioeconomic background, lack of parental education, and lack of access to dental care. Oral health plays an important role in children to maintain the oral functions and is required for eating, speech development, and a positive self-image. The review will focus on the prevalence, risk factors, and preventive strategies and the management of ECC.

Prevalence of dental caries in primary and permanent teeth and its relation with tooth brushing habits among schoolchildren in Eastern Saudi Arabia‬‬‬‬‬‬‬‬

Objectives:

To determine the prevalence of dental caries in the primary and permanent teeth, and evaluate the brushing habits of school children in Dammam, Kingdom of Saudi Arabia (KSA).

Methods:

This study was conducted at Dammam, KSA. Oral examination of the participants was conducted from February to May 2014. The total sample size for this cross-sectional study was 711. There were 397 children between the age of 6-9 years, who were examined for primary teeth caries, and 314 between the age 10-12 years were examined for permanent teeth caries. Primary and permanent dentitions were studied for decayed, missing, and filled teeth (dmft [primary teeth], DMFT [permanent teeth]).

Results:

The overall prevalence of dental caries in primary and permanent teeth was almost 73% (n=711). Among the 6-9-year-old, the prevalence of caries was approximately 78% (n=397) whereas, among the 10-12-year-old children, it was approximately 68% (n=314). Mean dmft value among the 6-9-year-olds was 3.66±3.13 with decayed (d) component of 3.28±2.92, missing (m) component of 0.11±0.69, and filled (f) component of 0.26±0.9. Mean DMFT value among the 10-12-year-old children was 1.94±2.0 with decayed (D) component of 1.76±1.85, missing (M) component of 0.03±0.22, and filled (F) of component 0.15±0.73. Daily tooth brushing had a positive effect on caries prevention, and this effect was statistically significant for caries in primary teeth.

Conclusion:

Although the prevalence of dental caries in primary and permanent teeth was not found to be as high as other researchers reported from different cities of KSA, still the prevalence was high considering the World Health Organization future oral health goals. Awareness should be provided to students, as well as, teachers and parents regarding the importance of good brushing habits and regular dental visits.

Prevalence and care index of early childhood caries in mainland China: evidence from epidemiological surveys during 1987-2013

Early childhood caries (ECC) is the most common chronic disease in young children. Its reported prevalence varies greatly across China. This systematic review aimed to explore the epidemiological characteristics of ECC in mainland China from 1987 to 2013. In total, 102 articles were included. The pooled national prevalence and care index (ft/dmft%) for ECC were 65.5% and 3.6%, respectively. The overall ECC prevalence declined from 77.9% during 1987-1994 to 56.4% during 2010-2013. The pooled ECC prevalence for children aged 1-6 years was 0.3%, 17.3%, 40.2%, 54.4%, 66.1%, and 70.7%, respectively. There was no significant difference in prevalence between boys (59.1%) and girls (58.9%); and the care index was also similar (8.1% versus 7.7%). Slightly higher ECC prevalence was observed in rural areas (63.5%) compared with urban areas (59.5%) (RR = 1.08, 95% CI: 1.02-1.14); but a much higher care index was reported in urban children (6.0%) than their rural counterparts (1.6%) (RR = 3.68, 95% CI: 2.54-5.35). The 2006-2013 map of ECC prevalence among 5-year-olds showed wide geographic variations across China. Four adjacent provinces, including Sichuan, Chongqing, Hubei, and Shaanxi, constituted the areas with the lowest ECC prevalence in mainland China.
