Background: An oily calcium hydroxide formulation proved over the last years to be highly efficient in promoting bone regeneration in closed defects as periapical lesions, cysts, or post-extraction defects. The aim of the present study is the assessment of the outcome of treatment of deep intrabony periodontal defects with an Open Flap Debridement) (OFD) + combination of {(30% Hydroxyapatite HAp + 70% ?-Tricalcium Phosphate granules mixed with an Oily Calcium Hydroxide Suspension (OCHS )} and compare the results with {(OFD) alone)}. The combination of OCHS& TCP was used in humans with a sort of positive results, and more conduction of studies was recommended. Material and method: The sample of this study composed of sixteen patients; each had at least two intrabony defect teeth. For each patient, one tooth was treated by OFD only (control group 16 teeth) and the other teeth (study group 16 teeth) were treated with OFD + a mixture of (OSTEON II- Korea) granules comprise of (30% Hydroxyapatite HAp + 70% ?-Tricalcium Phosphate) and OCHS (Osteoinductal®, Osteoinductal GmbH., Muenchen, Germany). The clinical parameters that were measured and recorded included (Plaque index PLI, Gingival index (GI), Gingival recession(GR) , Bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment level (CAL) and radiographical width & depth of the bony defect. These parameters were recorded before treatment (base line) & six months after the treatment. Results: The results after treatment revealed a highly significant reduction in all of the parameters except the PLI in both study & control groups compared to baseline (p < 0.001). The clinical results were indicated that the study group showed significant reductions of PPD and CAL mean values more than improvements obtained by the control group with significant difference (p < 0.05). Conclusions: An excellent postoperative improvement in clinical parameters was noticed in the study group more than control group and the differences were significant. Thus the present study has revealed that the treatment modality of OFD + a combination of granules comprise of (30% Hydroxyapatite HAp + 70% ?-Tricalcium Phosphate) mixed with oily Calcium Hydroxide suspension is successful, predictable and more beneficial than (open flap debridement) (OFD) alone in the treatment of deep intrabony periodontal defects.
The aim of the present research is to study different protein fractions in sera of children and adolescent with β –thalassemia major and minor and to compare the results with that of healthy control.One hundred fifty children and adolescents were enrolled in this study,including 50 patients with β- thalassemia major , 50 patients with β- thalassemia minor as pathological control group and another apparently 50 healthy individuals as a control group. The age of all studied groups ranged from (4-18)years.Total protein, albumin and immunoglobulins were estimated in sera of all subjects. A Significant decrease was found in the total protein and albumin&nb

This research is devoted to study the effect of different in weight percentage of Sio2 particles and glass fibers (5, 10, 15, 20) wt. % on the wear rate epoxy resin. The results show that the value of hardness increase with the increase for the weight percentage of reinforcing particles and fibers, while the wear rate decrease with the increase the load level of the reinforcing particles and fibers . The largest value of the hardness, and the lowest value of the wear rate for epoxy reinforced with 20% of SiO2, the wear rate increase in general with increasing the applied load.

Oral jelly is a semisolid preparation that could resolve problem associated withdosage form’s swallowing, especially in pediatric and elderly ones. This work aimedto prepare oral flurbiprofen (FBP) jelly to improve patient compliance. Heating andcongealing method was used to prepare FBP jelly using three different polymers (pectin,sodium carboxymethyl cellulose, and hydroxypropyl methylcellulose). The effect ofdifferent concentrations of pectin and sucrose on jelly properties was studied. Theresults revealed that both pectin and sodium carboxymethyl cellulose polymers gaveacceptable jelly appearance and consistency. It was also observed that the increase ofpectin or sucrose concentration had a significant impact on jelly viscosity. All pe

The aim of present study was to develop gel formulation of microsponges of poorly soluble drug meloxicam (MLX) in order to enhance the release and dissolution of MLX which is the limitation for preparation in topical forms. Also skin delivery is an alternative administration for MLX that can minimize gastrointestinal (GI) side effects and improve patient compliance. The microsponges of MLX were prepared by quasi-emulsion solvent diffusion method. The effects of drug:polymer ratio, stirring time and Eudragit polymer type on the physical characteristics of microsponges were investigated and characterized for production yield, loading efficiency, particle size, surface morphology, and in vitro drug release from microsponges. The selec
