           Instrumentation systems.

    • Abstract: Aims: Assess the quantity of apical extruded debris after instrumentation with ProTaper universal files, K3 files, and Wave One reciprocating file. Materials and Methods: Thirty lower premolars were used in this study. Teeth were randomly divided into 3 groups each one contained 10 samples as follow: Group1- Teeth were prepared with ProTaper universal files. Group2- Teeth were prepared with K3 files. Group3- Teeth were prepared with Wave One file. Debris that was apically extruded during canals preparation was collected in the centrifuge tubes, which previously were weighed. Centrifuge tubes were put for 5 days in the incubator with temperature of 70 °C to allow evaporation of moisture. After that centrifuge tubes that contained debris were weighed, and quantity of extruded debris was determined via subtraction the initial weight of centrifuge tube from the final weight of same tube, then collected data was analyzed statistically. Results: Statistical analysis revealed that, ProTaper group showed highest amount of apical extruded debris followed by Wave One group and, K3 group showed least amount of apical extruded debris. The difference between ProTaper group and Wave One group was not significant, but both of them had significant difference with K3 group. Conclusions: Within the limits of the current study, preparation of root canals with K3 files is better than other groups in terms of less extrusion of apical debris.

    • Abstract: Aims: The aim of this in-vitro study was to compare the retention force of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) clasps by mechanical cycling test simulating ten years of use. Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar, it is divided into 24 Co-Cr clasps, and 48 PEEK clasps which were subdivided into 24 clasps (2.4mm width), and 24 clasps (3.00mm width).Each group was further subdivided (n=8 clasps) into amounts of abutment undercut 0.25mm, 0.50, and 0.75mm undercuts. Mechanical cycling of each clasp was performed for 15000 times on its specific abutment crown. The retention force of each clasp in newton was measured every 1500 cycles by applying a tensile force using a universal tensile machine. Results: The retention force of Co-Cr clasps was higher significantly than the PEEK clasps retention force for the three undercuts. Deeper undercut showed a significantly higher retention force for both materials. All subgroups (except 0.75mm Co-Cr group) exhibit an increase in retention force after first 1500 cycles followed by gradual decrease till the end of 15000 cycles. Conclusions: The retention force of PEEK clasps with both widths along 15000 cycles of insertion/removal were lower than Co-Cr clasps but still sufficient for clinical use at 050, and 0.75mm undercut but not enough at 0.25mm undercut.

           Bleached Enamel: An in ...

    • Abstract: Aims: To investigate the effect of in-office dental bleaching techniques on the microhardness of enamel and the influence of post bleaching diode laser irradiation on the surface microhardness of bleached enamel. Materials and methods: Forty bovine teeth were prepared and then randomly allocated into two equal groups (n=20) according to bleaching technique as follows: CB: Conventional in-office bleaching technique and LB: Laser–assisted in-office bleaching technique. Each group was subdivided into two subgroups (n=10) according to laser irradiation setting as follows: C2: Conventionally bleached followed by diode laser irradiation at 2 Watt laser, C4: Conventionally bleached followed by diode laser irradiation at 4 Watt laser, L2: laser –assisted bleached followed by diode laser irradiation at 2 Watt laser and L4: Laser–assisted bleached followed by diode laser irradiation at 4 Watt laser. Vickers microhardness was assessed three times for all the specimens: before bleaching, 24 hours after bleaching and finally 24 hours after post bleaching diode laser irradiation. Paired samples t- test and independent samples t- test were utilized for statistical analysis. Results: Both bleached groups exhibited a significant decrease in micro harness after bleaching with no statically significant deference between them. Post bleaching diode laser irradiation at 2Watt and 4Watt resulted in significant increase in microhardness with no significant difference was evident between them.  Conclusions: Diode laser irradiation on bleached enamel had a positive influence on surface microhardness of enamel and it may represent a promising post bleaching treatment modality.

  • Pre-Orthodontic Myofunctional Trainers Appliance System: A Review

    • Abstract: Abstract: Malocclusion bearings a great weight internationally. Persistent oral habits produce alteration in the activity of orofacial muscles. Early diagnosis and treatment of the orofacial myofunctional disorders render countless welfares by minimizing related malocclusion and reducing the possibility of relapse after orthodontic treatment. Pre orthodontic trainers are innovative types of prefabricated removable functional appliances claimed to train the orofacial musculature; thus correcting malocclusion. This review aimed to search the literature for studies and case reports on the effectiveness of pre-orthodontic trainers on early correction of developing malocclusion and highlight particularly on its structural characteristics and its mechanism of action. Current literature provides sufficient evidence that these appliances are effective in treating Class II malocclusions especially those due to mandibular retrusion. Case reports on Class I malocclusion have reported relief of anterior crowding, alignment of incisors, and correction of deep bite with pre-orthodontic trainers. Promising results with pre-orthodontic trainers are realized in improved nasal breathing, improved swallowing pattern, and removal of habits like tongue thrusting and mouth breathing.
