A state of disturbed equilibrium known as oxidative stress occurs when the body's antioxidant system is unable to control the quantity of free radicals that are created. Free radicals interact with cell components, including protein, DNA, and lipid molecules, and cause tissue damage when present in large concentrations. At low concentrations, they are engaged in a variety of cell processes, such as cell signalling. An excessive amount of free radicals are produced, which contributes to the aetiology of a number of chronic inflammatory diseases, including periodontal disease.Periodontitis is a common chronic inflammatory illness that affects the tooth supporting tissues. It has a major global influence on dental health and overall well-being. Multiple factors, including immunological responses, microbial infections, and environmental variables, can contribute to the development of periodontitis. The development of periodontal tissue damage is significantly aided by oxidative stress, which is defined as an imbalance between reactive oxygen species (ROS) and antioxidants.Reactive oxygen species (ROS) are a major cause of cellular damage in periodontitis.

Dental implant is a good dental rehabilitation of the missing teeth. Scientific literature has evidenced that implant therapy obtains a success rate greater than 90%. With the increasing acceptance of dental implantation as a viable tooth replacement therapy, complications and failure rates have also increased proportionately. Complications and failures in implant dentistry can range from minor to major, reversible to irreversible, and problematic to detrimental. As a result, these clinical problems cause frustrations and disappointments for patients and dental professionals and cast doubts on the success of dental implant therapy. These problems can have many different levels of undesirable consequences that may lead to compromised or less than optimal clinical results for the patients, non-productive wasted clinical chair time, extra financial burden to the patient and dentist, create antagonistic tension in patients, and ultimately affect the reputation of the dentist and the profession. Complaints to regulatory colleges and litigations involving implant dentistry have also increased over the past decade.

La parodontite acuta conosciuta come la sesta malattia pi comune che colpisce pi di 740 milioni di persone nel mondo. La diagnosi della malattia parodontale dipende fortemente dall'esame dei parametri clinici normali. Tuttavia, essi simboleggiano il passato, piuttosto che il presente, o la progressione della malattia e la condizione clinica, la potenziale conseguenza del trattamento parodontale. In alcuni casi la malattia parodontale e i biomarcatori critici sono stati ampiamente testati per affrontare questi problemi e altri biomarcatori sono stati interpretati come test point-of-care (PoC). Lo scopo principale di questo libro di fornire una panoramica dei vari biomarcatori nella diagnosi e nel controllo delle malattie parodontali. Tra i test PoC migliorati fino ad oggi, la metalloproteinasi-8 attiva ha mostrato risultati promettenti per quanto riguarda i valori diagnostici e predittivi. D'altra parte, sono necessarie ulteriori ricerche per aumentare la sensibilit e la chiarezza combinando pi di un biomarcatore con l'integrazione di questi kit di test con valutazioni del rischio parodontale.
