Significance of Host immune system

The host immune system is the body's complex defense mechanism that plays a vital role in combating pathogens and infections. It faces challenges such as being adversely affected by smoking, struggling with the complexity of biofilm infections, and responding destructively to bacterial stimulation, which can lead to periodontal disease. Additionally, it interacts dynamically with pathogens like the hepatitis B virus and responds to foreign substances, emphasizing its importance in maintaining oral and overall health.
