A critical analysis of the sanitization strategies on root canal cleaning
Journal Title: Stomatos - Year 2013, Vol 19, Issue 37
Abstract
Objective: To assess the efficacy of irrigant solutions used in endodontic treatment in terms of cleanliness, smear layer removal and tissue dissolving potency by means of a systematic review of longitudinal studies. Method: Articles were identified in electronic bibliographies accessible via MEDLINE. Searches were run on the PubMed Database (http://www.ncbi.nlm. nih.gov/PubMed) for articles published from 1966 to January 10, 2012, using combinations of the following keywords: (Endodontic or root canal) and (Smear layer or clean* or tissue dissolution or organic dissolution) and (irrigants or NaOCl or sodium hypochlorite or Milton Solution or Dakin solution or Labarraque solution or chlorinated soda or chlorine or chloride or hypoclean or hypochlor or niclor or Chlor-xtra or chlorhexidine or chx or cloreximid or peridex or periogard or EDTA or Acid or citric or acetic or peracetic or malic or vinegar or citrate or Hydrogen peroxide or H2O2 or Iodine or iodide or povidone or povidine or PVP or Ozone or ozonated or MTAD or Tetraclean or Endoptc or Rc prep or Morinda citrifolia or Aquatine or hydroxyethylcellulose or cat’s claw or propolis). Studies were assessed for inclusion and exclusion criteria by two independent examiners. Results: The search returned 817 articles. Four (04) studies met the preestablished inclusion criteria and not the exclusion criteria. Teeth were assessed histologically at points 1, 2 and 3 mm from the root apex. Sodium hypochlorite at 5.25% and 6% was the only irrigating solution for which there is scientific evidence of root wall cleaning activity. Conclusions: Addition of ultrasound improved the cleaning potency of irrigant solutions. Isthmus regions had the lowest percentages of area free from debris.
