Abstract
BACKGROUND: Presence of cariogenic trace elements alters crystal lattice and size of crystal, thereby increases the susceptibility of tooth to dental caries. So, the aim of the study is to estimate cariogenic trace elements such as lead, copper, selenium, and cadmium in sound and carious permanent teeth using acid etch biopsy technique and also to correlate the presence of trace elements and its cariogenicity of an individual. MATERIALS AND METHODS: A total of 805 children were screened, and 60 children were selected in the age-group of 12-14 years living in same locality and depending on caries status, 30 children in group I (caries-free group) and 30 children in group II [carious group with decayed, missing, and filled teeth (DMFT) score 2-3]. The 3 µL of 0.5 M perchloric acid was taken in Eppendorf pipette and applied over the isolated area for about 3 seconds and aspirated. RESULTS: Unpaired t-test was used to compare between groups, and there was statistical difference in trace elements between carious group and caries-free group in both gender. CONCLUSION: The trace elements value was found to be more in carious group compared to caries-free group. HOW TO CITE THIS ARTICLE: Kumar MS, Krishnan R, John JB, et al.
