Maternal Smoking during Pregnancy Is Associated with Offspring Hypodontia.

Area of Science:

• Dental developmental anomalies
• Environmental epidemiology
• Teratology

Background:

• Environmental risk factors for hypodontia remain largely uncharacterized.
• Understanding these factors is crucial for prenatal counseling and prevention strategies.

Purpose of the Study:

• To investigate the association between hypodontia and maternal environmental exposures during pregnancy.
• Specific focus on smoking, alcohol, and caffeine consumption.

Main Methods:

• Clinic-based case-control study involving 89 hypodontia cases and 253 controls.
• Panoramic radiographs used for hypodontia diagnosis.
• Maternal questionnaires assessed smoking (active/passive), alcohol, and caffeine intake during pregnancy.
• Logistic regression analysis adjusted for confounders.

Main Results:

• Significant association found between hypodontia and maternal cigarette use during pregnancy.
• Higher daily cigarette consumption (≥10 cigarettes/day) showed a statistically significant increase in hypodontia odds (aOR=4.18).
• No significant associations were observed for passive smoking, alcohol, or caffeine consumption.

Conclusions:

• Maternal smoking during pregnancy is a significant risk factor for hypodontia.
• Further research with larger sample sizes and prospective designs is warranted to confirm these findings.
