[Conservative treatment of a case of periapical lesion with complications. Report of a case and calcium hydroxide therapy]. / Szövödményes periapicalis elváltozás konzervatív kezelése. Egy eset kapcsán a kalcium-hidroxidról.

A case and treatment of extraoral fistula on the chin-caused by necrotic pulp of lower left canine--is being presented. In this case an endodontic origin should always be considered from the aspect of differential diagnosis. Nonsurgical endodontic therapy, sometimes complimented by surgery, or extraction are the treatment modalities of these cases. For the treatment calcium hydroxide powder mixed with chlorhexidin gluckonat (0.1%) was used. Usage of calcium hydroxide paste was leaded to rapid and successful healing of extraoral lesions communicating with necrotic tooth.
