Sugar before bed: a simple dietary risk factor for caries experience

Area of Science:

• Dental Public Health
• Dietary Science
• Epidemiology

Background:

• Clinical care emphasizes caries risk assessment and prevention.
• Dietary habits, particularly free sugar intake frequency and timing, are crucial in caries development.
• Understanding specific dietary risk factors is essential for effective caries prevention strategies.

Purpose of the Study:

• To identify simple and reliable dietary risk factors for caries experience in adolescents.
• To investigate the association between free sugar consumption patterns and caries development.
• To provide evidence for targeted dietary interventions in caries prevention.

Main Methods:

• A cross-sectional observational study involving 128 adolescents aged 11-12.
• Data collected through clinical examinations (D4-6MFT, ICDAS stage 4), questionnaires, and 24-hour dietary recall interviews conducted by a dietitian.
• Assessment of free sugar intake, including consumption between meals, before bed, and total percentage.

Main Results:

• No significant differences in caries experience were found based on deprivation levels, sugar intake between meals, or total free sugar percentage.
• A statistically significant difference in caries experience was observed between adolescents consuming free sugars before bedtime and those who did not (p=0.002).
• Logistic regression indicated an odds ratio of 2.4 for developing cavities (caries into dentine) associated with pre-sleep free sugar consumption.

Conclusions:

• Consumption of free sugars before bedtime is a significant risk factor for developing caries into dentine in adolescents.
• Targeting bedtime sugar intake may be a key strategy in preventing adolescent dental caries.
• Simple dietary assessments, like bedtime sugar consumption, can aid in caries risk assessment.
