Antimicrobial effects in oral microenvironments by a novel herbal toothpaste

Area of Science:

• Oral microbiology
• Dental hygiene
• Antimicrobial agents

Background:

• Dental plaque harbors anaerobic, gram-negative, and malodor-producing bacteria.
• Effective oral hygiene is crucial for managing these bacterial populations.
• Novel formulations are continuously explored to enhance antibacterial efficacy.

Purpose of the Study:

• To compare the antibacterial effects of a novel herbal toothpaste containing zinc against a control fluoride toothpaste.
• To evaluate the impact on anaerobic organisms, gram-negative bacteria, and malodor bacteria in dental plaque, tongue scrapings, and cheek surfaces.

Main Methods:

• A double-blind, randomized study involving 44 adults.
• Baseline and post-treatment oral microbial samples (plaque, tongue, cheek) were collected.
• Microbiological analysis quantified anaerobic organisms, gram-negative bacteria, and malodor bacteria.
• Samples were collected 12 hours and 4 hours after brushing over 21 days.

Main Results:

• No significant baseline differences were observed between groups.
• The herbal toothpaste showed 42-68% reduction in anaerobic bacteria at 12 hours, increasing to 46-80% at 4 hours.
• Gram-negative bacteria reductions ranged from 49-61% at 12 hours, increasing to 54-69% at 4 hours.
• Malodor organism reductions were 22-42% at 12 hours, increasing to 60-72% at 4 hours.

Conclusions:

• Brushing with the novel herbal toothpaste significantly reduced key oral bacterial groups compared to the control.
• These antimicrobial effects were evident 12 hours post-brushing and further enhanced 4 hours after brushing.
• The herbal formulation demonstrates potential for improved oral microbial control.
