The periodontium, comprising the gums, bone, and surrounding tissues, serves as the foundation of a healthy dentition. Its integrity significantly influences the function, aesthetics, and longevity of teeth. A healthy periodontium is essential for the success of various dental treatments, including dental prosthetics, restorations, endodontic therapy, and orthodontic care. A compromised periodontium can lead to poor treatment outcomes and further deterioration of periodontal tissues during the treatment process. This can result in a range of issues, including tooth loss, decreased oral function, and compromised aesthetics. Research has consistently shown a strong association between iatrogenic factors and periodontal destruction. The periodontium plays a vital role in determining the function, aesthetics, and longevity of the dentition. A healthy periodontium is essential for successful dental treatments, and an interdisciplinary approach is crucial for complete rehabilitation offunction and health. By working together, dental professionals can provide comprehensive care, achieve optimal treatment outcomes, and promote long-term oral health.
