[Experience of organ spare sialolitiasis treatment using sialoendoscopy]. / Opyt organosberegayushchego khirurgicheskogo lecheniya sialolitiaza s ispol'zovaniem sialoskopii.

The aim of the study was to evaluate the effectiveness of organ spare sialolitiasis treatment by sialoscopy-guided techniques. The study included 317 patients with parotid and submandibular sialolitiasis. In 22 patients conventional surgical approach was used because of distal location and larger size of concrements, while in 295 miniinvasive sialoscopy-guided procedures were performed. The use of sialoscopy-guided approach drastically diminished the rate of submandibular glands extirpations (performed in 5% of patients), as well as early and long-term surgical complications.

[Osteostimulating effect of bone xenograft on bone tissue regeneration].

The aim of experimental case-control study performed in 28 dogs divided in 2 groups was to assess local tissue reactions on bone xenograft transplantation; dynamics of bone remodeling and formation at the site of bone defect wall contacting with bone xenograft; dynamics and mechanisms of xenograft remodeling. Transplantation of xenograft in conventional bone defects did not cause inflammatory of destructive reactions because of high biocompatibility of the material. At transplantation site active fibrous bone trabeculae formation filling the spaces between xenograft participles was observed. On the 90th day newly formed bone showed lammelar structure. Simultaneously from the 42d day the invasion of cell elements from recipient bed into the material was seen leading to xenograft resorption. The observed dynamics may be assessed as gradual substitution of xenograft with newly formed host bone structures.

[The experience of a clinical trial of bioceramic-based materials in dentistry]. / Opyt klinicheskoi aprobatsii materialov na osnove biokeramiki v stomatologii.

Bioceramics-based materials manufactured in Russia were experimentally and clinically tried with the aim of optimizing repair osteogenesis of the jaws. Powder, granules, and porous blocks of hydroxyapatite alone and mixed with tricalcium phosphate may be effectively used for plastic repair of osseous pouches and post-operative defects of the jaws in surgical treatment of periodontitis, periradicular cysts of the jaws, and for filling the wells after removal of teeth.

[A preclinical study of the effect of the animal polysaccharide chonsurid on reparative osteogenesis of the jaws]. / Doklinicheskoe izuchenie vliianiia zivotnogo polisakharida khonsurida na reparativnyi osteogenez cheliustei.

Experimental studies making use of morphological and x-ray methods demonstrated that in comparison with control (filling of mandibular bone defects with blood clots) chonsuride, an animal polysaccharide, promoted earlier filling of postoperative bone cavities with connective tissue replacement of this tissue with coarse-fiber bone tissue. Secondary restructuring and mineralization of bone regenerate were enhanced as well.

[Variants in the arrangement of the tooth roots in the alveolar arches of the human jaws based on computed tomographic data]. / Varianty raspolozheniia kornei zubov v al'veoliarnykh dugakh cheliustei cheloveka po dannym komp'iuternoi tomografii.

Anatomo-topographic relationship of the teeth roots were studied by means of computer tomography (CT) on 44 passportized skulls with mandibles of people who died in the age of 20 to 52 years. Conseguently, sections of mandibles and maxillae were made out of these preparations and peculiarities of the teeth roots locations in alveolar arches were studied by craniometric method. Comparison of CT results and measurements of sections showed that CT is an informative method of assessment of the teeth roots anatomo-topographic relationship that permits to attain general true qualititative indexes, allowing to evaluate objectively the available variants of the alveolar arch structure and the teeth roots location without disturbance of the anatomic material integrity.

[Experience in using computed tomography in the diagnosis of diseases of the maxillofacial area]. / Opyt ispol'zovaniia komp'iuternoi tomografii v diagnostike zabolevanii cheliustno-litsevoi oblasti.

Thirty patients aged 19 to 70 suffering from various diseases and injuries of maxillofacial organs and tissues (chronic odontogenic osteomyelitis, sinusitis, malignant and benign neoformations of the jaws and perimaxillary soft tissues, injuries to facial skull) were examined using computer-aided tomography. The method is described in detail, its potentialities in the diagnosis of the said diseases and injuries are demonstrated.
