ABSTRACT

Avaliar, em estudos longitudinais, a eficácia das soluções irrigantes utilizadas no tratamento endodôntico sobre a limpeza, remoção da smear layer e poder de dissolução tecidual, através de revisão sistemática. Método: Empregaram-se fontes de catalogação bibliográfica identificadas eletronicamente pelo portal MEDLINE (http://www.ncbi.nlm.nih.gov/PubMed), a partir de 1966 até 10 de janeiro de 2012. Na estratégia de busca empregou-se a combinação dos unitermos: (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). Os estudos foram selecionados por dois revisores, independentes, que determinaram os critérios de inclusão e exclusão. Resultados: A busca apresentou 817 artigos relacionados. Quatro (04) estudos satisfizeram os critérios de inclusão e exclusão preestabelecidos. A avaliação histológica foi realizada a 1, 2 e 3 mm do ápice radicular. O hipoclorito de sódio a 5,25% e 6% foi a única solução irrigante a apresentar evidências científicas de ação de limpeza sobre as paredes dos canais radiculares. Conclusão: A utilização do ultrassom melhorou o potencial de limpeza das soluções irrigantes. As regiões de istmo apresentaram menor percentual de áreas livres de detritos...


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...
