Material and methods: Nineteen cases with 24 implant were enrolled for standardization. Radiographical measurement undertaken by a periapical and OPG radiographs after implant placement, then after16 weeks later, again a second periapical and OPG radiographs were taken for measurements using Dimaxis 3.2.1. Software program to estimate marginal bone height of both sides of implant and its changes during times of evaluation. Results: 19 medically fit patients, male and female with age 22-65 years, twenty four implants with average bone loss 0.59 mm mesialy and 0.60 mm distally at T0 as standered base line in compared to 0.98mm mesialy and 1.11mm distally at T1as average bone loss. There was a significant bone resorption in both sides in relation of implant size and in comparison to time of placement and after 16 weeks according to statistical analysis. Conclusion: OPG and periapical views are a good parameter for evaluation of successful implant and monitoring of the prognosis and stability and durability, as these radiographs more available in most dental centers and clinics with less cost.

AIMS: This study aims to estimate the efficacy of Ostene as bone hemostatic agent clinically and experimentally and their effect on the ease of operation in clinical dental practice. MATRIALS AND METHODS: For experimental part: Fifteen males rabbits were divided into three groups according to the time interval for hemostasis measurement, five rabbits in each group. Each group subdivides into other three groups according to study material "ostene, gelfoam, control". On femoral bone, three holes were made. After bleeding started, study material was placed inside holes, then a uniform piece of cotton was applied with gentle pressure, then hemostasis measured using the gravimetric method. For the clinical part: after complete extraction, a piece of study material was implanted inside the tooth socket and covered with uniform cotton for hemostasis, then hemostasis measured using the gravimetric method. RESULTS: For experimental part: study result revealed that the comparison between two local hemostatic agents (ostene and gelfoam) groups for hemostatic effect show Ostene has superiority effect over gelfoam in control bleeding at all interval times. Friedman test revealed a significant difference between study materials P =0.00 (P ≤ 0.05). For the clinical part: clinical measurement, ostene showed significant over gelfoam at 1min, 30 min While there were no significances between ostene and gelfoam at 5min,10min. Regarding visual analog scales for assessing bleeding and ease of operation, ostene, when comparing it with gelfoam, appeared better than gelfoam. CONCLUSIONS: Hemostatic effect of ostene is superior to gelfoam experimentally and after tooth extraction.

Aims:The aim of this study is to evaluate the histopathological findings of healing phases in secondary wound defect on rabbit´s tongue, dressed with N-butyl -2-Cyanoacrylate (Histoacryl) tissue adhesive. Materials and Methods: Twenty domestic male rabbits had been selected. Two defects were done on each half of the tongue, 5mm oval shape, the right one left without covering, the left one covered by a thin layer of Histoacryl. Animals could be divided into four groups, each group contain five rabbits, according to sacrificing date into 3 days, 7 days, 14 days, and 30 days. Tongue specimen were collected after sacrificing the rabbit immediately, then divided into two halves, the right half was control one and the left half was the study one, giving off further two subdivisions for each group. The specimen were placed in formaldehyde and sent for histopathological examination regarding inflammatory and reepithelialization scoring. Results: The histopathological findings of this study revealed that there was a significant difference of inflammation between the two groups at 3 days, one week, one month, of tongue at p-value < 0.05, while there was no significant difference at two weeks period. In reepithelialization of the tongue a significant difference at 3 days at p-value < 0.05, and no significance at one week, two week, and one month. Conclusion: This study concluded that histoacryl tissue adhesive accelerate healing by decreasing inflammation, and inducing reepithelialization of mucosal secondary wound defects.
