COMPARISON OF PEDIATRIC SYRUPS ON MICROHARDNESS AND SURFACE ROUGHNESS OF DIFFERENT RESIN RESTORATIONS: AN IN-VITRO STUDY

Objective: The study objective was to compare the alterations in microhardness and surface roughness (SR) of three
distinct resin-based restorations commonly employed in pediatric dentistry under continuous exposure (at baseline, 7, 14, and 21 days) to frequently utilized pediatric syrups.
Materials and methods: In this in vitro study, three pediatric syrups used as immersion agents were
amoxicillin+clavulanic acid, paracetamol, and haematinic syrup. The materials evaluated were Compomer,
Microhybrid, and Nanofill composite resin restorations. The study included 180 caries-free, non-restored deciduous
molar teeth without developmental anomalies that were extracted due to pre-shedding mobility. The surface
microhardness and SR were measured with a Vickers microhardness durometer and a contact profilometer
respectively. ANOVA was used for intra- and inter-group data comparisons at a 5% significance level using SPSS
software.
Results: On day 21, the antibiotic-micro-hybrid group had the highest microhardness (52.95±0.62). The compomerhematinic group had the lowest microhardness (13.22±0.33). The SR of the compomer-paracetamol group was the highest (1.47±0.43), while the micro-hybrid-antibiotic group had the lowest (0.83±0.07). Intragroup comparisons showed significant differences (p<0.01), showing a decrease in material microhardness with an increased exposure period. The compomer subgroups exposed to paracetamol and haematinic and the nanofill composite exposed to haematinic syrup exhibited a significant difference (p<0.01).
Conclusion: The microhardness of compomer-paracetamol, compomer-antibiotic, and nanofill-paracetamol
subgroups increased over the study period. The SR of the compomer and nanofill materials treated with haematinic
syrup and compomer-paracetamol subgroup increased considerably.
