Summary
During dental sedation, immobility significantly reduces salivary secretion and coughing risk. This finding highlights the importance of patient stillness for safer dental procedures under deep sedation.
Area of Science:
- Dental Medicine
- Anesthesiology
- Physiology
Background:
- Cough reflex control is vital for safe dental sedation.
- Saliva accumulation is a key factor triggering cough during procedures.
- Patient body movements may increase salivation during sedation.
Purpose of the Study:
- To compare salivary secretion in patients with and without body movements during dental sedation.
- To investigate the impact of immobility on salivation under deep sedation.
Main Methods:
- Salivary weight was measured in 27 patients with intellectual disability undergoing deep sedation.
- Measurements were taken during dental treatment using midazolam and propofol.
- Data on body movements, Bispectral Index (BIS), and propofol concentration were collected.
Main Results:
- Salivary weight was significantly lower in the without-movements state (0.03 g) compared to the with-movements state (0.11 g).
- Bispectral Index (BIS) was significantly lower during immobility.
- No significant difference in propofol concentration was found between the two states.
Conclusions:
- Deep sedation decreases salivary secretion.
- Immobility further reduces salivation during dental treatment.
- Reduced salivary secretion due to immobility is a beneficial factor for safe dental sedation.
