[A dermaerosion case dealing with a leakage of a chemically irrigable solution (NaOCI solution)]

This paper is a report regarding a dermaerosion case dealing with a leakage of a chemically irrigable solution in a 3 year old boy. We are continuing to observe the dermal changes during as he grows. Also, we carried out a pathological experiment on a rabbit and a patch test of the derm of seven people. The following conclusions were obtained. 1. We observed the dermaerosion of an epithelium repair after a complete elapse of one year. The dermaerosion of the corium could not be repaired but changed the color of the derma of the patient who recovered after a lapse of 2 years and 8 months. 2. We recognized in the rabbit experiment that a 12% H2O2 solution damaged the corium of the rabbit over a period of 24 hours. The 12% H2O2 solution was four times higher, for we normally used a 3% H2O2 solution. 3. When we used a 10% NaOCl solution (which we usually use in the widening of the root canal) for 20 minutes on the derma of the rabbit, the derma damaged the epithelium but over a period of 40 minutes the solution we used on the derma of the rabbit damaged the corium. 4. When we used a NaOCl and H2O2 solution the reaction on the skin of the rabbit is weaker than when only one solution was used. 5. We used 0.5% NaOCl and 0.3% H2O2 solutions for the biceps of 2 atopic diseased people and 5 normal people for 48 hours, with no change noticed in their biceps. 6. The results may be summarized as follows.(ABSTRACT TRUNCATED AT 250 WORDS)
