| Abstract|| |
Introduction: Certain factors in mothers could be risk indicators for certain diseases in their children. Hence, this study was undertaken to assess maternal risk indicators for the development of early childhood caries in their children. Methodology: A comparative, cross-sectional study was designed among 180 mother-child pairs attending various Anganwadi centers. Demographic, dietary, oral hygiene practices and other necessary information were collected from mothers using a structured questionnaire. Caries status and amount of plaque were recorded through clinical examination. Nonstimulated saliva from mothers was cultured for mutans streptococci (MS). Data were analyzed using SPSS version 17. Chi-square, Student's t-test, and logistic regression were used. A P ≤ 0.05 was considered statistically significant. Results: In the study group, 73.3% of mothers had caries as compared to only 53.3% mothers in control group. While mean DMFT and mean DMFS of mothers in the study group was 3.78 ± 3.91 and 8.37 ± 12.2, respectively, the same for the mothers in the control group was 2.66 ± 3.01 and 5.8 ± 5.3. Sixty (66.7%) out of ninety mothers in the study group had a high MS count as compared to only 40 (44.4%) mothers in control group (P = 0.003). Conclusion: The present study showed that high salivary MS count and decay in mothers could be important risk indicators for the development of caries in their children.

| Introduction|| |
Early childhood caries (ECC) is the presence of one or more decayed (noncavitated or cavitated lesions), missing (due to caries), or filled tooth surfaces in any primary tooth in a child under the age of 6 years. The disease of ECC has serious implications on the primary dentition, yet it remains relatively unexplored and poorly defined in many developing countries., Even though the role of microorganisms, feeding and dietary practices is well established in the development of ECC, it has not been able to control the disease, thus shifting the focus of researchers to other additional risk factors.
Research into the etiology of caries in children has implicated transmission of mutans streptococci (MS) from mothers to their children, poor oral hygiene of mothers, high sugar intake in mothers, high caries experience in mothers, health behavior of mothers, which in turn may be influenced by many factors such as cultural, social, and socioeconomic status. Yet, relatively little attention has so far been given to identify such maternal risk indicators for caries development in children in India.
Hence, this study was undertaken to assess whether certain of these maternal factors could be important risk indicators for the development of caries in their children. If so, such maternal risk indicators might ultimately be useful in developing necessary strategies for prevention of ECC at a primordial level.
| Methodology|| |
A comparative, cross-sectional study was designed among 180 mother-child pairs attending various Anganwadi centers in Bengaluru. The study was approved by the Institutional Ethical Committee. Informed consent was obtained from mothers to examine them and their children.
One hundred and eighty children aged 3–5 years attending 10 Anganwadi centers in Bengaluru South, which were randomly selected from the list of Anganwadis, were chosen and included in the study; out of 312 children, after applying the inclusion and exclusion criteria, a total of 180 mother-child pairs were included. Ninety children with one or more carious lesions formed the study group along with their mothers, and ninety caries-free children formed the control group along with their mothers. Children or mothers suffering from systemic diseases, on chemotherapy or radiotherapy, on long-term oral medication, or who had consumed antibiotics in the past 3 months were excluded from the study.
Information on demographic and other factors was obtained from mothers through an interview using a structured questionnaire, which was pretested on twenty mothers who were not part of this study.
Children and their mothers were examined on an ordinary chair using mouth mirror and community periodontal index probe with artificial illumination. Caries experience was recorded using DMFT index. Only frank cavitation was considered as caries for the present study. Amount of plaque was recorded using Silness and Loe index. Mothers were allocated into study and control groups exclusively on the caries status of their children.
Salivary sample collection and processing
Whole unstimulated saliva was collected from mothers and cultured on MSB agar prepared according to Gold et al. Plates were incubated at 37°C in a 5% CO2 atmosphere for 48 h and colony-forming units were counted. A colony count of ≥100 (100 × 104) was considered as high.
Data were analyzed using SPSS software version 17 (IBM SPSS statistics). Categorical variables were analyzed using Chi-square test. Difference in mean carious experience, mean plaque scores, and mean salivary MS counts in mothers of two groups was tested using Student's t-test. Logistic regression was used to estimate odds ratio of caries experience in children in relation to different maternal variables. A P ≤ 0.05 was considered statistically significant.
| Results|| |
In the present study, the mean age of mothers was 25.58 ± 4.18 years. About 50% of mothers were illiterates, 93% of mothers were homemakers, and 90% of mothers had a family income of <Rs. 5000 a month (not mentioned in the table) in both groups. No significant association was found between ECC and mothers' age, level of education, occupation, or income of the family [Table 1].
About 75% of mothers in both groups consumed sugar <2 times/day. More than 60% of mothers in both groups had never visited dentist. No significant difference was found in their mean plaque score either [Table 2].

Sixty (66.7%) out of ninety mothers in the study group had a high MS count as compared to only 40 (44.4%) mothers in control group. This was statistically significant with P= 0.002. Furthermore, in the study group, 66 (73.3%) out of 90 (100%) mothers had caries compared to only 48 (53.3) mothers in the control group, and this was statistically significant with P < 0.001. While mean DMFT and mean DMFS of mothers in study group were 3.78 ± 3.91 and 8.37 ± 12.2, respectively, the same for the mothers in control group was 2.66 ± 3.01 and 5.8 ± 5.3 (P = 0.03). In addition, mothers in the study group had a significantly higher mean number of missing teeth (0.89) compared to mothers in control group (0.41) [Table 3].

| Discussion|| |
ECC is a serious sociobehavioral and dental problem that afflicts infants and toddlers,, with the disease concentrating disproportionately in deprived families.
Maternal characteristics such as age, education, socioeconomic status have been associated with caries in their children by some studies.,,,, Low socioeconomic status and low maternal education are commonly associated with economic and familial stresses that place a child at risk for ECC., However, in the present study, no significant difference was found between mothers of the two groups with respect to age, level of education, occupation, or family income. This could be due to the fact that usually all children attending Anganwadis are from low socioeconomic background.
Frequency of dental visit, maternal sugar consumption, oral hygiene practices, amount of plaque in mothers have also been linked to childhood caries by some previous studies.,, However, in the present study, no such differences were found among mothers of two groups with respect to their frequency of dental visit, sugar consumption, oral hygiene practices, or amount of plaque. This could also be attributed to the common background of low socioeconomic status among mothers of two groups.
The two maternal characteristics which were associated with caries in their children in the present study were the caries experience and levels of salivary MS. The odds ratio of having a child with caries was 9 times higher in mothers having caries as compared to caries-free mothers. Mean DMFT and mean DMFS were significantly high among mothers of study group as compared to mothers in control group. This is in accordance with the results of some studies.,,,,, Furthermore, mothers in study group had more missing teeth than their control group counterparts. This could be suggestive of negligence toward their and their children's oral health.
A strong association was found between maternal MS levels and caries in their children. The odds ratio of having a child with caries was over 2.5 times greater in mothers with high MS counts as compared to mothers with low MS counts. Many previous studies in the past have found that mothers who harbored high levels of MS with high DMFS scores shared similar genotypes of Streptococcus mutans with their 2–3-year-old children. Thus, mothers with high MS levels and high DMFS scores may affect the child's early infection with S.mutans resulting in an increase of ECC.,,
The limitation of the study was that some mothers and children may have been misclassified as caries free as examination was carried out with minimum instruments and lighting on an ordinary chair. The pattern of sugar consumption is another area where there could have been a bias as form, consistency, and time of intake were not recorded.
| Conclusion|| |
The present study showed that dental caries and high salivary MS counts in mothers could be important risk indicators for the development of caries in their children. However, detailed longitudinal studies would be required to better explain the effects of these maternal risk indicators on development of childhood caries.
