[Evaluation of maintenance therapy in patients treated in 1986 and 1987 by the periodontal service of the University of Chile Dental School].

Abstract

It was determined if Periodontic students of the years 1986 and 1987 indicated periodical maintenance care in their patients treated of Periodontal disease. 598 cards were revised. 130 of them showed the indication of maintenance care. These patients received registered letters for controlling. Only 20 of them complied. A clinical examination was made: Radiographic control wasn't made because there wasn't a radiographic Kardex of old radiographies of previous years.
