Which is the best method for cleaning and toilet of a cavity?

The best method for cleaning and toileting a cavity is water. During dental procedures, especially when preparing a cavity for a filling, it's important to ensure that the area is free of debris, bacteria, and contamination. Water effectively rinses away debris and provides a clean surface for further treatment.

Using water as a cleaning solution is advantageous because it is non-reactive, non-toxic, and safe for both the patient and the dental materials that may be used subsequently. It helps in washing away blood, saliva, and other residual substances from the cavity, ensuring better adhesion for restorative materials.

While alcohol and organic acids can also interact with dental tissues, they are not suitable for thorough cleaning of a cavity because they may also cause damage or alter the properties of dental materials. Citric acid can help in etching dental tissues but is not a suitable cleaning agent due to its potential for damage to tooth structure and sensitivity issues. Thus, water remains the most effective and safest option for cleaning a cavity in dental practice.
