Introduction: Lead is the major environmental pollutant. There is an association between dental caries with blood lead concen trations and tooth lead content, however not much has attempted to correlate salivary lead levels with dental caries. Objective: There has been an increase in dental caries among populations across the globe, It a multifactorial disease, one of the factors could be lead content which has been correlated with a high incidence of caries but salivary lead levels have not yet been extensively tested. Hence this study was conducted to test the association of salivary lead and its effect on caries. Methods: 60 children belonging to 3-5 and 12-14 years of age groups, selected who were categorised into low caries group (deft/ DMFT less than 2) and high caries group(deft/DMFT more than 5) and 5 cc of unstimulated saliva were collected. The salivary lead levels were recorded and applied for statistical analysis, Annova test has been applied to test the association using SPSS software. Results: The high dental caries children reported with higher salivary lead concentration this difference is being reported to have a positive difference. The mean lead level is being reported to be 2.9 and 2.8 for students from 3-5 and 12-14 years students respectively. This difference is reported to be a statistically significant difference. Conclusion: Lead poisoning, particularly causing a risk to children when they live in old houses in deprived urban areas can even affect the caries susceptibility of the child. Health care professionals need to be made aware of the risk factors for caries progression beyond the traditional risk factors for caries such as this trace element.
