LITERATURE REVIEW AND CASE REPORTS: The literature concerning the aetiology, symptomatology and therapy of complications during root canal irrigation is reviewed. Three cases of inadvertent injection of sodium hypochlorite and hydrogen peroxide beyond the root apex are presented. Clinical symptoms are discussed, as well as preventive and therapeutic considerations.

This study describes a case of eye burn induced by sodium hypochlorite used as an irrigant during root canal preparation.. A 24-year-old female endodontist was using an operating microscope during root canal treatment, and as the root canal was irrigated, the pressure cannula burst and the irrigant (3.5% sodium hypochlorite) came into direct contact with her left eye. She immediately sought ophthalmologic emergency care for pain, redness of the cornea, burning sensation, photophobia, intraocular pressure, and blurred vision. The initial treatment consisted of washing the eye with saline solution and administering analgesic and anti-inflammatory (steroid) medications. One day after the accident, a topical demulcent and hydroxypropyl medication were applied to the eyeball (conjunctiva), the eye was bandaged for 24 hours, and rest was prescribed for 7 days. Eight days later, a corneal ulcer was diagnosed, and antibiotic and anti-inflammatory (steroid) medications were used.. Vision was restored without any sequelae 4 weeks after the accident. The endodontist was instructed to apply control medication (Lagricel; Sophia SA, Caracas, Venezuela) for 3 months and to return for ophthalmologic follow-up every 6 months.. Sodium hypochlorite is an effective antibacterial irrigant indicated for the treatment of root canal infections. The tissue cytotoxicity highlights the need to inform the patient of the risk factors of accidents and enhance care with individual protection equipment for the patient and the professional during clinical procedures.

Sodium hypochlorite is used in endodontic therapy as an intracanal irrigant during hand, mechanical, and ultrasonic instrumentation of the root canal space. Regardless of the technique utilized, particular attention must be given to the appropriate and safe use of this chemical solution. A case is presented in which a 5.25% sodium hypochlorite solution was accidentally splashed in a patient's eyes during endodontic therapy. Ocular irrigation was performed immediately and continued for 10 min. The patient was promptly taken to an ophthalmologist for further treatment and follow-up. When chemical trauma of the eye by sodium hypochlorite solution is sustained, the entire surface of the affected eye(s) and the fornices must be thoroughly irrigated. This is best accomplished with a continuous stream of normal saline from a 1-I bag which is attached to an intravenous line with a 16-gauge Teflon catheter placement sleeve affixed to the distal end of the line. Arrangements must then be made for immediate evaluation, treatment, and consultation by an ophthalmologist.
