title: Long term evaluation of biomaterial application in surgical treatment of periodontosis.
abstract: Regenerative treatment of periodontally damaged teeth is a demanding task. Advantages which comes with use of biomaterials are mainly connected with fact that traditional, surgical treatment protocols often do not lead to bone regeneration. The aim of this research was to evaluate clinical and radiological effectiveness of surgical periodontal treatment (with application of HA-Biocer, Biogramu, Bio-Oss) after eight years prior to surgical protocol. Clinical evaluation consisted of measuring pocket depths with perio probe, than evaluation of API (approximal plaque-index) hygiene index (-). Calculation of modified sulcus bleeding index - SBI (%) by Muhlemann and Son was done. Engelberger, Marthaler and Rateitschak index on xrays was calculated. Routine check up eight years after surgical treatment of periodontitis with use of biomaterials was conducted on 32 patients (20 woman, 12 men). The group of patients was divided into: 28 patients with chronic periodontitis (CP), and 4 patients with general aggressive periodontitis (GAP). Eight years after surgical treatment increase of bleeding areas were observed - in all applied biomaterials. For Bio-Oss average percent of SBI 45.2% (+/-24.3), for Biogran 62% (+/- 36.2) and respectively for HA-Biocer 51% (+/-33.2) API index (%) on teeth proximal surfaces was estimated for Biogran 47%, BioOss - 46.5% and for HABiocer 45.6%. Mean pocket depth (mm) has decreased - in case of all applied biomaterials. Radiological index was also calculated. Decrease of index value was stated. Outcomes of 8 years study indicate, decrease of oral hygiene, increase bleeding, decrease of Engelberger, Marthaler, Rateitchak index. It is necessary to perform routine check up of and control on oral hygiene. It seems to be important to mobilize patients to preserve high oral hygiene.
