An investigation on the biostite clinical effects associated with Tetracycline powder in the treatment of defect resulting from LAP teeth (Research)

Surgical therapies combined with topical or systemic antibiotic administration have recently become popular for the treatment of patients with localized aggressive periodontitis (LAP) The goal of the present study was to investigate the clinical effects of Biostite combined with Tetracycline in angular defects of molar teeth among patients with LAP, as compared with debridment method in the control group. Four patients, referred to the periodontics department, with bilateral defects in both jaws were selected. each patient had two experimental regions and two control ones, Totally, 16 regions were in vestigated (8 experimentals and 8 controls). Surgical operations were of full-thickness flap cy and crescent incision. In the experimental group, Biostite mixed with Tetracycline solution was placed on the defects whereas the ccontrol samples were just debrided. Clinical indices were measured at three stages: Phasel (pre-operation), the first operation and recently operation (6 months later). To do the statfistical analysis paired - Sample t-test was used. The results revealed that pocket depth indices, before the first and the second operations, were not statistically significant in the test group, as compared with the control group (P>0.05). The level of attachment and Loe sillness plaque index did not show any significant difference (P>0.05). The amount of bone fill in both groups revealed a significant differencian the second operation comparing to the first one (P > 0.05), however, This index was similar in both groups.Bone crest recession in the test group was 0.69 and that of control was 1 which the differnce was not significant Thus, it is concluded that Biostite application combined with Teracycline does not make any signifcant difference, as compared with debridement technique which may be attributed to the complete hygiene observation in both groups.
