Hydrogen Peroxide Fumigation in Dental Office Environment

Status Completed

Clinical Trial Summary

The study's null hypothesis posits no significant difference in bacterial levels in the dental office environment before and after implementing hydrogen peroxide (H₂O₂) fumigation. The study comprised 30 participants, 18 females and 12 males, all diagnosed with moderate caries decay (ICDAS 3 and 4) in their mandibular molars, averaging 42.2 ± 8.3 years in age. Sample size calculations for 30 microbiological plates in each group utilized G*Power software (Kiel University, Germany), factoring in prior research, with a significance level of 0.05, effect size (d) of 0.72, 95% confidence interval, and 85% power. Aerobic bacterial content in the dental office air was assessed using the Koch sedimentation method. The study employed 60 Petri dishes with Columbia Agar and 5% Sheep Blood. During caries treatment, thirty plates were opened and sealed 40 minutes later, while another set of thirty plates was opened and closed 60 minutes post-fumigation. Measurements were taken 1 meter above the ground and 2 meters from the patient's mouth. After 48 hours of incubation at 37°C, microbiological contamination was calculated as CFUs (colony-forming units) in one cubic meter using the formula: L = a × 1000 / (πr² × k). Fumigation involved a 20-minute treatment with 6% hydrogen peroxide biosanitizer (Saniswiss, Switzerland) via a compressed air device (Fumi-Jet, Kormed, Poland). The process included 3 minutes of fumigation and a 17-minute waiting period for the chemotoxic effect, with 45 ml of 6% hydrogen peroxide sprayed in a 20 m² room.
