ROLE OF SYSTEMIC DISEASES IN ENDODONTICS

Systemic diseases and oral infections are closely related because they both share many associated risk factors. General health conditions of a patient may influence the healing of periapical lesions and therefore the outcome of the root canal treatment. Both systemic and tooth-based factors can have a negative impact on the success of the endodontic treatment.The outcome of treating endodontic infections might be poorer by patients with general medical conditions such as diabetes mellitus, hypertension, renal diseases, immunosuppressive conditions, etc. Tooth-based factors such as the quality of the chemo-mechanical preparation of the root canal, the quality of the root canal obturation, as well as the preoperative existence of periapical lesions, are also significant factors for the success of the root canal treatment. Dental practitioners must be aware of relationship of systemic conditions, disorders and endodontic treatment outcomes, because this may have influence in the healing outcome rather than just acting as a causative etiologic factor, and provides valuable information on the prognosis of endodontic treatment.
