Selective or stepwise removal of deep caries in deciduous molars: study protocol for a randomized controlled trial

Area of Science:

• Pediatric Dentistry
• Cariology
• Restorative Dentistry

Background:

• Incomplete caries excavation in deciduous teeth is debated.
• Evidence on success rates and restoration integrity is limited.
• Patient and cost factors are largely unexamined.

Purpose of the Study:

• To compare selective versus stepwise incomplete excavation for deep caries in deciduous molars.
• To evaluate tooth survival, restoration integrity, and treatment costs.
• To assess patient, parent, and dentist preferences.

Main Methods:

• Prospective, multicenter, randomized controlled trial.
• 300 children (3-9 years) with deep caries in deciduous molars.
• Comparison of selective (one-step) vs. stepwise (two-step) excavation, with follow-up at 6, 12, 24, and 36 months.

Main Results:

• Data on tooth survival, restoration success, and retreatment needs will be collected.
• Subjective assessments and cost analyses will be performed.
• Longitudinal data on restoration integrity will be analyzed.

Conclusions:

• Results will inform clinical decision-making for treating deep caries in deciduous molars.
• A comprehensive approach considering multiple criteria will be feasible.
• Evidence-based recommendations for excavation techniques will be provided.
