Objectives: Caries removal efficacy in terms of microbiological burden using Tungsten Carbide Bur No. 330, Polymer bur, BRIX 3000, and ErCr: YSGG Laser.
Methods: Class I open dentinal caries was selected and divided into four groups ( = 15) depending on caries excavation methods. Group I: Tungsten carbide (TC) No 330-bur; Group II: Polymer bur (Smart bur); Group III: Brix 3000 gel; Group IV: Erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er: Cr: YSGG) laser. Two samples of carious material, before and after caries excavation, were taken and cultured on blood agar plates. Multiple comparison of mean CFUs/ml between different groups was done using Dunn's test and Wilcoxon signed-rank test.
Results: Group I showed significantly lesser mean CFUs/ml followed by Group IV as compared to Group II and Group III.
Conclusion: Within the parameters and limitations of the present study, ErCr: YSGG laser can be a helpful aid as a minimally invasive method of caries excavation.

A Randomized Controlled Trial Evaluating the Clinical Performance of Bioactive Restorative Material and Resin-modified Glass Ionomer Cement in Carious Primary Molar Restorations.

Aim And Objectives: To evaluate the clinical performance (marginal discoloration, surface texture, and retention) of bioactive restorative material (ACTIVA) and resin-modified glass ionomer cement (RMGIC) in carious primary molar restorations at 6 and 12-month intervals.
Materials And Methods: The split-mouth randomized controlled trial comprised 31 children aged 5-8 years having contralateral matched pair of carious primary molars with an International Caries Detection and Assessment System (ICDAS) II score 5. Sixty-two teeth were randomly allocated into two groups: group I-ACTIVA ( = 31) and group II-RMGIC ( = 31).
Evaluation of residual carious dentin detection methods after cavity preparation: a randomized clinical trial.

Article Synopsis
- The study addresses the challenge of effectively removing caries from dentine without damaging too much healthy tissue, as there is no current diagnostic tool to determine the limit for caries removal.
- Researchers conducted a randomized trial with 90 patients at a dental clinic in northeastern Nigeria, testing three diagnostic methods to find residual caries after cavity preparation: visual-tactile, caries detector dye (CDD), and laser fluorescence (LF).
- The effectiveness of these methods was assessed by an independent investigator through the examination of residual caries and bacterial culture samples collected from the prepared cavities.
3D-printed tooth for caries excavation.

Department of Prosthodontics, University of Würzburg, Pleicherwall 2, 97070, Würzburg, Germany.
Background: To date, no suitable model tooth has been available for all standard restorative and prosthodontic procedures. To fill this gap, a realistic multilayer tooth with enamel, dentin, integrated caries, pulp, and electrometric and X-ray imaging abilities was developed. The aim of this study was to test the printed tooth while focusing on caries excavation and pulp capping.

Article Synopsis
- This study aimed to evaluate how Spanish dentists manage deep caries and exposed pulps in permanent teeth through an anonymous online survey targeting dental professionals.
- The survey, which gathered 538 responses, revealed that most dentists preferred complete caries excavation for shallow/moderate cases but leaned towards selective excavation for deeper lesions; over 80% commonly performed direct pulp capping for asymptomatic teeth.
- Findings indicate that practices often diverged from established guidelines, highlighting that patient preferences, pain history, and hemostasis techniques significantly influenced treatment decisions.

Objectives: The objective of this clinical trial was to evaluate and compare the clinical and radiographic successes of three bioactive endodontic cements (BEC) including novel portland cement-based material releasing fluoride, resin-modified silicate glass cement, and pure tricalcium silicate-based cement-in the treatment of primary molars diagnosed with reversible pulpitis via indirect pulp capping.
Methods: Eighty-six (86) participants with previously untreated first and second primary molars were included in this study. The teeth were randomly allocated into three groups: pure tricalcium silicate-based cement, resin-modified silicate glass cement, and novel portland cement-based material releasing fluoride.
