A short-term plaque study using Lactitol as a non-sugar sweetener

Area of Science:

• Dental Science
• Nutrition Science
• Biochemistry

Background:

• Dental caries remains a significant public health concern.
• Dietary sugars are a primary factor in dental plaque formation and demineralization.
• Non-cariogenic sugar substitutes are sought to mitigate caries risk.

Purpose of the Study:

• To evaluate the effect of lactitol on dental plaque pH, weight, and microchemical composition in children.
• To compare the cariogenic potential of lactitol with sucrose.
• To assess lactitol's suitability as a non-cariogenic bulk sweetener.

Main Methods:

• A short-term plaque study involving 12 children aged 8-12 years.
• Administration of lactitol and sucrose in solution and sweet forms.
• Measurement of plaque pH at rest and post-consumption intervals (5, 10, 20, 30 minutes).
• Analysis of plaque weight and microchemical composition (carbohydrates, calcium, phosphorus, protein) after 3 days.

Main Results:

• Lactitol consumption did not lower plaque pH to levels associated with enamel demineralization.
• Significant reduction in plaque formation and plaque carbohydrate content was observed with lactitol.
• Increased levels of calcium, phosphorus, and protein were found in plaque following lactitol consumption.

Conclusions:

• Lactitol demonstrated a non-cariogenic profile in this pediatric study.
• Lactitol's ability to reduce plaque formation and alter its composition suggests protective dental effects.
• Lactitol shows potential as a safe and beneficial bulk sweetener for dental health.
