Final answer:
The most effective way to reduce root canal microbes is complete debridement of the root canal, which removes all the infected tissue and prevents reinfection. Intracanal medication can help, but mechanical cleaning remains critical. Proper oral hygiene and fluoride use are also important in preventing tooth decay.
Step-by-step explanation:
The most effective means to reduce root canal microbes is B. complete debridement of the root canal. This process involves thoroughly cleaning out the root canal system to remove the infected tissue, debris, and bacteria. This helps to prevent re-infection and allows for proper healing of the tooth. Intracanal medication may assist in reducing the microbial load, but the key to success is the removal of all infected material.
Some ways microbes contribute to tooth decay include producing acids that break down tooth enamel and leading to cavities. The most important cariogenic species of bacteria is Streptococcus mutans. Good hygiene, such as tooth brushing and flossing, along with the use of fluoride and antiseptic mouthwashes, are crucial in combating microbial growth and preventing tooth decay.
