Research in periodontics has increased exponentially in recent years, allowing progress in the diagnosis and treatment of the disease. In what aspects has so much progress been made? In techniques for early detection of periodontal diseases (gingivitis and periodontitis): Radiological technology: with the incorporation of computer processes, more agility has been achieved in obtaining and processing data obtained from x-rays, especially with the incorporation of the 3D technique . Thanks to the three-dimensional radiographic image, it is possible to find more precise and appropriate treatments in each specific case. This allows more precise detection of the levels of deterioration of periodontal tissues in the event of disease, as well as reducing radiation levels. Less risk and, at the same time, clearer and higher quality images. Genetic studies: these studies allow us to determine a patient's risk of contracting periodontitis based on their genetic inheritance. Thanks to them, it is even possible to identify certain genes that regulate the inflammatory response. Biomarkers: the use of certain biomarkers can help us in the diagnosis of periodontal diseases and determine the future appearance of chronic periodontitis. Thus, they make possible a much more specific action to avoid the loss of bone support and maintain oral health in a good state. Cervicular fluid analysis: in the same line as the previous improvements, many researchers are developing new techniques in periodontics to measure the presence of chemical elements in the cervicular fluid, the liquid found in the groove between the tooth and the gum. This allows determining the correlation between its levels and the existing types of periodontitis.
