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 tissue fluids.
Predictive factors of efficacy of
periradicular corticosteroid injections for lumbar radiculopathy.
Por otro lado, si queremos tratar las raices nerviosas, al tener estas una sensibilidad mayor a la oxidacion las concentraciones de ozono en el area
periradicular deberan ser mas bajas, entre 12 y 20 [micron]g/mL y tendrian un efecto analgesico de forma inmediata por la accion oxidante del ozono sobre los mediadores algogenicos, que se forman en el sitio danado del tejido y participan en la transmision de la senal nociceptiva al sistema nervioso central asi como sobre los receptores perifericos del dolor.
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 tissues (1).
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 status.
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 periodontitis.
In this case, tooth #61 was extracted because of a fistula formation and
periradicular lesion.
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 tissues.7,8
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
