Endodontic treatment is necessary after certain dental trauma or in the presence of a large carious lesion, associated with signs of irreversible pulpal inflammation. The treatment of apical periodontitis is a real public health issue. The endodontic success rate is between 68 and 85%. Indeed, some studies show that systemic diseases such as diabetes can increase the prevalence and bone loss associated with apical periodontitis. Other studies identify apical periodontitis as a factor that can potentiate symptoms caused by inflammatory diseases such as cardiovascular disease and diabetes by increasing the level of inflammatory cells in the blood.

However, since 2014 the European Society of Endodontology has recommended establishing a higher level of evidence to ensure the link that these pathologies may have. For this, it is necessary to assess the criteria that may influence the healing of apical periodontitis.

Endodata has been developed by dental surgeons specializing in endodontics. The purpose of this software is to improve the clinical follow-up of patients and to establish a clinical and radiological database. In this context, the creation of a clinical database including data for all root canal treatment is of high interest.
