The use of oral biofluids in orthodontics
Recently, the use of biofluids and the investigation of biomarkers seems to become an important tool leading to personalized diagnosis and personalized treatment planning in the medical science. Same way, novel possibilities can be offered in dentistry and orthodontics by the collection and analysis of the saliva and the gingival crevicular fluid (GCF). Various clinical conditions could be estimated with this simple, non-invasive, non-radiological developing diagnostic method. Some examples include the identification of several salivary bone metabolism biochemical markers involved in orthodontic tooth movement, while other biomarkers have been associated with orthodontically induced inflammatory root resorption or periodontal inflammation. Further, salivary biomarkers could potentially be useful in the diagnosis of obstructed sleep apnea and the treatment outcome. It is also noteworthy that peri-miniscrew implant GCF biomolecules alterations were observed and correlated to mini-implant success or failure. Moreover, GCF biomarkers were found to be associated with the efficiency of orthodontic and functional treatment of growing patients. Finally, the finding that the level of certain salivary or GCF biomolecules increases during the pubertal growth spurt is of great importance and may provide a quantitative way of assessing skeletal maturity. Despite these investigations, the clinical applicability of the use of biomarkers is still limited, nevertheless a rapid development in this field is expected in order to optimize orthodontic diagnosis, treatment progress and orthodontic treatment outcome.
