Summary Background/Aim: Many irrigation solutions are used during root canal treatment. It is unacceptable to confuse irrigation solutions with anesthetic solution and inadvertently inject the patient. After such an error, local and systemic serious complications can be seen in the patient. The purpose of this case report is to show how careless use of etilendiamin tetraacedic acid (EDTA) can result in important complications, and offer some treatment methods for curing symptoms resulting from such complications. Case Report: A 17% EDTA solution, was inadvertently injected in the buccal mucosa of a 20-year-old male during routine root canal treatment. Severe pain, bleeding and mucosal swelling occurred shortly after the injection. Irrigation with saline was performed by sliding the mucoperiosteal flap at the injection site. Then the flap was sutured primary. At the control one week later, there were no areas of necrosis in the patient, but ecchymosis occurred. Decalcified areas were not detected in dental volumetric tomography examination. Conclusions: The dentists must apply the precautions of EDTA irrigation solution during the root canal treatment and manage the treatment of this clinical complication.

“…This thin, amorphous structure covers prepared root canal walls and occludes the orifices of dentinal tubules (3). The smear layer contains inorganic and organic substances (3,4). Rigorous removal of necrotic remnants of pulp tissue, microorganisms, and microbial toxins from the root canal system is necessary for endodontic success (5).…”

Aim: The aim of this study was to evaluate the effectiveness of two instrumentation and irrigant techniques in smear-layer removal from root canals. Methodology: Thirty single-rooted teeth were randomly divided into two groups. Group 1 (continuous irrigation) was prepared using Self-adjusting file, and group 2 (manual irrigation; conventional needle irrigation) was prepared using with ProTaper file system. Groups were irrigated using sodium hypochlorite (5%) as an initial irrigant following MTAD in a closed system. Canals were bisected and examined by scanning electron microscopy. Smear layers were evaluated using a five-point scoring system with 2500x magnification. Results: Smear layers were eliminated in the coronal, middle, and apical thirds of the root canal, respectively, in 93%, 80%, and 60% of samples in the group 1, and 67%, 60%, and 27% in the group 2, of the coronal, middle, and apical thirds of the root canals, respectively. Evaluation by SEM showed continuous irrigation differed not-significantly from the manual irrigation group in all areas (P >0.05). Conclusions: Smear layer can be removed properly with suitable irrigation methods. How to cite this article: Kaya S.
