Hydroxyapatite (HA) plays a vital role in biological structures like tooth enamel and bones. Our research delves into its properties to better understand its potential applications in health and dentistry.
• Objective: Analyze HA's ability to support bone regeneration and tooth enamel restoration.
• Methodology:
◦ Samples were extracted and subjected to controlled conditions of temperature and acidity.
◦ The interaction of HA with calcium and other minerals was studied to evaluate its performance under simulated biological environments.
• Findings:
◦ HA showed remarkable resilience and adaptability in replicating the hardness and durability of natural tissues.
◦ Further studies confirmed its effectiveness in reducing bacterial absorption and supporting remineralization.
To understand the interaction between hydroxyapatite and bacteria, we analyzed the bacterial uptake of HA under various conditions.
• Objective: Assess HA's ability to resist bacterial growth and support oral health.
• Methodology:
◦ Optical density (OD 0.650) of the supernatant was used to measure bacterial activity.
◦ Samples were exposed to bacteria for one week at controlled temperatures, followed by a thorough evaluation of the oral cavity.
• Findings:
◦ Results showed a significant decrease in bacterial colonies due to HA's interaction with calcium and magnesium ions.
◦ After five weeks of testing, HA effectively reduced bacterial activity, promoting a healthier oral environment.
