Sanchís JM, Peñarrocha M, Bagán JV, Guarinos J, Vera F. Incidence des kystes radiculares dans une série de 125 lésions périapicales chroniques. Rev Stomatol Chir Maxillofac 1997;98:354-8.
The incidence of radicular cysts in 125 chronic periapical lesions was studied in 36 cases of periapical surgery (28.8%), and to 89 tooth extractions (71.2%). Histopathology revealed 18 radicular cysts (14.4%) and 107 lesions corresponding to chronic apical periodontitis (C.A.P.) or granulomas (85.6%). Cholesterol clefts, a fibrous capsule and presence of a cavity were more common in the cysts, significant differences being observed with respect to chronic apical periodontitis.
