Therefore, an ideal repair material should be biocompatible, dimensionally stable, easy to handle, and radiopaque; should have sufficient hardness and compressive strength; and should not be affected by the moisture of periradicular
Predictive factors of efficacy of periradicular
corticosteroid injections for lumbar radiculopathy.
Root canal treatment may be defined as the combinations of procedures including mechanical instrumentation of root canal system, its chemical debridement, and filling with an inert material to restore or maintain the health of periradicular
However, the increased concentration of NaOCl can cause adverse reactions, such as the irritation of periradicular
tissues, in case of leakage of irrigant solution, and allergic reactions, due to its high toxicity (19).
Prevalence of apical periodontitis and factors associated with the periradicular
Study of association between Parvimonas micr a and pulp dominant pathogens in the infected root canals with chronic periradicular
periodontitis (in Chinese).
(29) compared antimicrobial effect of PDT and 2.5% NaOCl on facultative anaerobic microorganisms on patients who were diagnosed irreversible pulpitis or periradicular
In this case, tooth #61 was extracted because of a fistula formation and periradicular
These bacterial colonies, especially enterococcus (E.) faecalis, can't be eliminated from the canals completely by either single or multiple-visit endodontics.3 According to reports, single-visit endodontics might not be as efficient in reducing endotoxins as multiple-visit treatment.2 Intra-canal medicaments are used in multiple visit root canal treatment to augment the mechanical procedure.6 The inter-visit placement of canal medication basically aims at reducing and retarding growth of bacteria and, hence, preventing the risk of inflammation in periradicular
Prevalence of periradicular
periodontitis associated with crowned teeth in an adult Scottish subpopulation.
Their extravasation in the periradicular
tissues or leakage into the oral cavity is found to be associated with severe inflammation, hematoma formation, chemical burns, neuronal damages, choking, endophthalmitis, ototoxicity and severe hypersensitivity reactions.6,8,9
