[Surgery of juvenile periodontitis]

The clinical efficiency of surgery for juvenile periodontitis (JP) followed-up for 13.5 (6-21) months was evaluated in this paper. A total of 102 teeth in 43 patients were included in the study, of them, three-wall infrabony pocket was in 74 teeth, two-wall infrabony pocket was in 21 teeth, one-wall infrabony pocket was in 7 teeth. After scaling, root planning and flap procedure, the rate of clinical efficiency was 74.51%, of which, three-wall infrabony pocket was 85.14%, two-wall infrabony pocket was 52.38%, one-wall infrabony pocket was 28.57%. The results show that if teeth with JP were effectively treated in time, better clinical efficiency can be obtained likewise, and if sectional osseous defects were properly treated, osseous restoration still is possible.
