Experimental Investigation of the Influence of Chlorhexidine Gel on the Implant-Abutment Connection: OAJBS Publishers

Experimental Investigation of the Influence of Chlorhexidine Gel on the Implant-Abutment Connection by Vasilios Alevizakos* in Open Access Journal of Biomedical Science (OAJBS)

Background: The aim of this study was to determine the effect of chlorhexidine gel on removal torque of abutment prosthesis screws in vitro.

Methods: 60 implants (BEGO Semados® S/RI 4.1, BEGO Implant Systems GmbH & Co. KG, Bremen, Germany) were embedded in acrylic resin for study set-up. The abutments (S/RI 4.1 SUB-TEC WI, BEGO Implant Systems GmbH & Co. KG, Bremen, Germany) were fixed with prothesis screws with 25 Ncm on the implants and were loaded for 10.000 cycles with 250N in a static material testing machine. The implemented study consisted of three groups (n=20). Group 1 (control group) were loaded under dry conditions. Group 2 was filled with a saliva substitute only (Sialin-Sigma solution, Sigmapharm Arzneimittel GmbH, Vienna, Austria), group 3 was filled with a saliva substitute and additional with chlorhexidine gel (Chlorhexamed 1% GEL, GlaxoSmithKline Consumer Healthcare GmbH & Co. KG, München, Germany). Statistical analysis was performed using ANOVA (significance level p<0.05).

Results: The control group showed the smallest range of removal torque (19.85 Ncm ± 1.42 Ncm) while group 2 showed 20.32 Ncm ± 2.61 Ncm and in group 3 was 19.74 Ncm ± 2.96 Ncm. No significant differences between the three groups were evaluated.

Conclusion: Within the limits of this in-vitro study, it can be concluded that the application of chlorhexidine gel did not show any significant effect on the removal torque on abutment screws after loading.

Facile Synthesis of Chitosan Nanoparticle with Different Features and Histopathological Ultrastructural Study on The Effect of Its Bio-complex with Bovine Serum Albumin in Mice Liver by Maged El-Kemary* in Open Access Journal of Biomedical Science (OAJBS)   We have synthesized chitosan nanoparticles (CS-NPs) with different characteristics using ionic gelation method. Results showed that the synthesized CS-NPs with different concentrations of trisodium polyphosphate (TPP) are irregular – spherical shaped with narrow size distribution and high stability. The microporous chitosan was also synthesized with new features characterized with different techniques as SEM, EDX, FTIR and BET. The synthesized microporous chitosan has a surface area and pore volume of 245.571m 2 /g and 0.155cm 3 /g respectively. Its microporous surface is functionalized with carboxyl and amine groups. Histopathological and ultrastructural studies of mice liver were performed using optical and scanning electron m...

Review on Analysis of Breast Tumor with Methods of Treatment: OAJBS Publishers

Review on Analysis of Breast Tumor with Methods of Treatment by Nagham Mahmood Aljamali* in Open Access Journal of Biomedical Science (OAJBS) Breast malignance is the greatest public in ladies, with a high incidence in North America and Eastern Europe, medium in Southern Europe and the Middle East and low in the Far East. Breast malignance is the second most common malignance in the world after lung malignance, and since it happens a lot, the doctors asked the women to examine themselves by themselves, in order to discover the signs of the disease early before it spreads. It is possible that this disease can be treated after being diagnosed by a specialized doctor and determining the type of tumor in the breast, and the surgeon removes the breast completely and starts chemotherapy about 6 doses, then radiotherapy, how many sessions will be determined by the doctor, and then hormonal therapy, a medicine called Tamoxafin or any medicine determined by the doctor, and it is possible. This ...
