This randomized controlled trial evaluated the effectiveness of Er, Cr: YSGG laser versus conventional rotary instrumentation for caries removal in 90 children aged 6-10 years. The laser treatment resulted in significantly lower anxiety and pain levels, with Group B showing better USPHS scores in sensitivity and marginal staining. Overall clinical efficacy was similar between groups (83.33% vs. 91.11%, P = 0.18).
Key findings
- Group B had significantly lower Venham scores and pulse rates post-treatment (P < 0.01).
- Group B showed better USPHS scores in sensitivity, secondary caries, and marginal staining (P < 0.01).
- Group B demonstrated greater improvement in masticatory function (P < 0.05).
- Group B had a lower incidence of adverse events compared to Group A (P = 0.01).
Why it matters
The findings suggest that Er, Cr: YSGG laser may enhance pediatric dental care by reducing anxiety and pain during caries removal, potentially leading to a more positive experience for young patients.
