ABSTRACT
AIM: An in vitro study to evaluate and compare the remineralization potential of commercially available remineralizing agents containing silver diamine fluoride (SDF), casein sucrose phosphate (CSP), casein phospho peptide-amorphous calcium phosphate (CPP-ACP) using DIAGNOdent. MATERIALS AND METHODS: Thirty freshly extracted premolars for orthodontic treatment were collected. Specimens were randomly divided into 3 groups of 10 each: group I: SDF, group II: CSP, group III: CPP-ACP. The samples were subjected to DIAGNOdent analysis for recording the baseline values. Specimens were placed in demineralizing solution incubated at 37°C for 72 hours. DIAGNOdent values were recorded after demineralization. Following this, remineralization procedure was carried out using 3 different remineralizing agents: group I samples with SDF, group II with CSP, and group III with CPP-ACP. The remineralization procedure was performed to group I once and repeated for 14 days for group II and group III and storage solution was changed every 24 hours. The samples were subjected to DIAGNOdent analysis after 72 hours, 7 days, and 14 days and values were recorded. RESULTS: The data were analysed using Statistical Package for the Social Sciences (SPSS) with analysis of variance (ANOVA) and post hoc test. Intragroup comparison of DIAGNOdent readings showed a highly significant difference between baseline, postdemineralization, and postremineralization values. Among intergroup comparison, SDF showed maximum remineralization values followed by CSP and CPP-ACP, respectively. CONCLUSION: Silver diamine fluoride, CSP, and CPP-ACP are proven to possess remineralization potential. CLINICAL SIGNIFICANCE: A comparative evaluation of these three remineralizing agents will aid in identifying most potent and effective agent in treating initial caries lesions in an effective noninvasive and child-friendly manner.

ABSTRACT
AIM: To evaluate and compare the antibacterial efficacy and horizontal depth of penetration of various irrigants into the dentinal tubules when used alone and when combined with lasers. MATERIALS AND METHODS: An experimental study was done on 42 single-rooted teeth. Access cavity preparation was done and the canals were enlarged up to a ProTaper file size F2 of length 25 mm. They were inoculated with 0.1 mL of Enterococcus faecalis and the samples were randomly assigned into six different groups of seven teeth each. The following irrigation systems were used individually and in combinations-normal saline, sodium hypochlorite, chlorhexidine gluconate, diode laser and erbium, chromium: ytrrium scandium gallium garnet laser (Er,Cr:YSGG laser). The colony-forming units (CFU) of bacteria before and after disinfection and the penetration depth of different groups were determined. Statistical analysis was done by an ANOVA test. RESULTS: The highest number of CFU of bacteria was shown by the group where saline was used and it also showed the least penetration depth compared to that of the Er,Cr:YSGG laser group. CONCLUSION: Er,Cr:YSGG laser when used along with sodium hypochlorite and chlorhexidine gluconate showed the highest reduction in the CFU of bacteria and the greatest penetration depth when observed under a stereomicroscope. CLINICAL SIGNIFICANCE: Laser-assisted irrigation regimes have a high antibacterial efficacy and more penetration depth into the dentinal tubules.
