[A clinical x-ray evaluation of the efficacy of hydroxyapatite with collagen in treating periodontitis and radicular cysts]. / Kliniko-rentgenologicheskaia otsenka éffektivnosti gidroksiapatita s kollagenom pri lechenii parodontita i radikuliarnykh kist.

One-year follow-up of 20 patients with radicular cysts and 16 ones with medium-severity chronic periodontitis demonstrated the efficacy of hydroxylapatite with collagen. Active formation of osseous tissue at the site of cysts, in the periodontal osseous pockets, and at the apexes of interdental septa was observed 6 to 7 months after the treatment.

[Characteristics of the structure of the palatine suture and interalveolar septum in normal children and in diastema]. / Osobennosti stroeniia nebnogo shva i mezhal'veoliarnoi peregorodki u detei v norme i pri diasteme.

The palatine suture is wider in 6-14-year-old children with diastema than in normal ones; this suture is commonly direct and rarely tortuous. This may be due to its inadequate ossification. The width of the diastema does not depend on the suture width. An acuminate interalveolar septum predominates in normal children, but diastema and the child's age are conducive to its flattening. Orthodontic treatment normalizes the width of the palatine suture and the shape of the interalveolar septum, but in many patients the results are not stable.
