What is the impact of saliva on the cleanliness of pits and fissures?

Saliva plays a role in the oral environment, including the cleanliness of pits and fissures in teeth. It contains enzymes and antibodies that help in breaking down food particles and reducing the bacterial load. While saliva does provide some degree of cleansing by flushing out debris and neutralizing acids produced by bacteria, it does not completely cleanse pits and fissures.

These anatomical features tend to trap food particles and plaque, making them difficult to clean thoroughly through saliva alone. Therefore, relying solely on saliva for maintaining cleanliness in these areas is inadequate for effective oral hygiene. Regular brushing and flossing, along with professional dental cleanings, are necessary to ensure that pits and fissures are kept clean and free from decay. This understanding underscores the significance of preventive measures, such as the application of sealants, to protect these vulnerable areas from caries.
