Qualitative and Quantitative Evaluation of the Effects of Different Chelating Agents on the Calcium Content of Root Canal Dentin Using Atomic Absorption Spectrophotometer: An Study.

AIMS AND BACKGROUND

Evaluation of the effects of different chelating agents on the calcium loss of root canal dentin.

MATERIALS AND METHODS

Around 65 single-rooted teeth were collected and decoronated. The working length was determined, and biomechanical preparation was done in a crown-down fashion using the HyFlex Control Memory rotary nickel-titanium (Ni-Ti) system until apical preparation of 30.04. Canals were irrigated with chelating agents and sodium hypochlorite between each file insertion. Based on the type of chelating agents used, the samples were randomly divided into five groups ( = 13)-group I, liquid ethylenediaminetetraacetic acid (EDTA); group II, EDTA and chlorhexidine (CHX); group III, etidronic acid; group IV, SmearClear; and group V (control), distilled water. The total volume of the solution used was collected, and calcium ion release was quantified using an atomic absorption spectrophotometer. The qualitative analysis was done by observing the acetylene (CH)/air flame. Images were obtained for each sample, compared, and analyzed.

RESULTS

With respect to the control group, groups IV and I show a statistically significant difference compared to groups II and III ( < 0.05). Qualitatively, the highest intensity was observed in group IV and the least intensity in group III.

CONCLUSION

SmearClear showed significantly higher decalcifying capability compared to EDTA, EDTA and CHX, and etidronic acid. Hence, its combined use with an organic solvent can be recommended for efficient smear layer removal.

CLINICAL SIGNIFICANCE

Minimally invasive endodontic treatment is aimed at preserving the strength of the treated tooth without compromising cleaning effectiveness. Therefore, comparing the efficacy of different chelating agents will be promising with respect to maximum calcium loss both qualitatively and quantitatively.
