To estimate the effectiveness of sodium perborate with carbamide-peroxide (urea peroxide) to remove the staining of non-vital discolored teeth. Comparative cross sectional study. Dental department of operative dentistry, LUMHS, Jamshoro Sindh, Pakistan, from December 15-12-2014 to June 15-6-2015. A total of 160 single rooted teeth with intact clinical crowns have been collected. Using human blood, the teeth were discolored. With the vita shade guide, shades of discolored teeth were taken. Each tooth was handled with the root canal. 2 mm of root-canal-filling material cleaned under the junction of cement-enamel. In addition, it was then coated with glass ionomer cement 1 mm thickness. Teeth were divided randomly into two groups based on bleaching content used in the pulp chamber; group-A (C.P): 16% Carbamide-peroxide. Group-B (S.P): tetra-hydrate sodium-perborate mixed with distilled water. After 21days, the results were checked for efficacy. The analysis included a total of 160 teeth extracted (80 teeth extracted in each group). In group A, 78 (51.7%) found effectiveness compared to 73 (48.3%) in group B. The experimental groups showed statistically similar bleaching results at the end of twenty one days and p value found to be not significantly different (p=0.078). With a significant result, intracoronal bleaching of non-vital colored teeth is less invasive, comparatively safe and effective to remove the staining of non-vital discolored teeth.

We assessed the efficiency of two shaping file systems and two passive ultrasonic irrigation (PUI) devices for removing filling material during retreatment. The mesial canals from 44 extracted mandibular molars were prepared and obturated. The teeth were randomly divided into two groups, and then one group was retreated with Reciproc R25 (VDW, Munich, Germany) (n = 44) and the other group was retreated with 2Shape (TS, Micro Mega, Besançon, France) (n = 44). A micro-computed tomography (CT) scan was taken before and after the retreatment to assess the volume of the filling material remnants. The teeth were then randomly divided into four groups to test two different PUI devices: Irrisafe (Satelec Acteon Group, Merignac, France) and Endo Ultra (Vista Dental Products, Racine, WI, USA). The teeth in Group A were retreated with 2Shape to test the Endo Ultra (n = 22) device, the teeth in Group B were retreated with 2Shape in order to test the Irrisafe (n = 22) device, the teeth in Group C were retreated with Reciproc to test the Endo Ultra (n = 22) device, and Group D was retreated with Reciproc to test the Irrisafe (n = 22) device. A third micro-CT scan was taken after the retreatment to test the PUIs. The percentage of Gutta-Percha (GP) and sealer removed was 94.75% for TS2 (p < 0.001) and 89.3% for R25 (p < 0.001). The PUI significantly enhanced the removal of the filling material by 0.76% for Group A (p < 0.001), 1.47% for Group B (p < 0.001), 2.61% for Group C (p < 0.001), and by 1.66% for Group D (p < 0.001). 2Shape was more effective at removing the GP and sealer during retreatment (p = 0.018). The supplementary approach with PUI significantly improved filling material removal, with no statistical difference between the four groups (p = 0.106).

Objectives: Role of niacin in decreasing cardiovascular accidents by lowering the levels of Apo-B in hyperlipidemic patients. Background: In hyperlipidemia, there are high levels of atherogenic lipoproteins leading to higher risk of atherosclerotic cardiovascular events. Patients with dyslipidemia use statins as a mainstay of therapy over last many decades. Recent studies show that apolipoproteins play a major role in formation of atheromatous plaque, thus there is an urgent need to study the effects of lipid lowering medication on apolipoprotiens levels. Study Design: Cross sectional analytical study. Setting: Sheikh Zayed Hospital Lahore (Department of Biochemistry and Chemical Pathology). Period: 12 weeks from July to Sep 2014. Materials and Methods: Recently diagnosed hyperlipidemic patients (n=44) were selected for the study purpose and divided into two equal groups; A and B. Each group was given different medication. Group A took only statin while group B took a combination of statin and niacin. Blood samples were taken at the start of medication and then after completion of 12 week time period. Results: At the start of the treatment there was no significant difference in the Apo B cholesterol level between the two groups (p value 0.972). However, after the end of 12 week duration, there was a significant reduction in the Apo level of group B taking statin and niacin as compared to group A taking statin alone (p value 0.003). Conclusions: Niacin has cardio-protective role when used in combination with niacin.

BACKGROUND: Laryngeal Mask Airway (LMA) placement is now considered a common airway management practice. Although there are many studies which focus on various airway techniques, research regarding difficult LMA placement is limited, particularly for anesthesiologist trainees OBJECTIVE: To assess the effectiveness of Laryngeal Mask Airway (LMA) placement after induction with propofol or thiopentone in one hundred day case urological patients. METHODS: An analytical, non interventional, cross sectional comparative study. Patients were divided into Group A (Propofol Group n=50) received propofol (2.5mg/kg) and Group B (Thiopentone group n=50) received thiopentone sodium (4-6 mg/kg) IV. Management of anaesthesia was identical in both groups. Standard monitoring was including NIBP, pulse oxymetery and ECG was done. Co-induction with done with midazolam 0.1 mg/kg body weight. LMA was inserted after adequate level of anaesthesia and then assessed. The presence of gaging, coughing, laryngospasm and movement were noted , recorded by a colleague anaesthetist who entered the induction room during the two minutes assisted ventilation phase and was not aware of the type of induction agent. Statistical analysis was done by using SPSS version 10. The mean and standard deviation was calculated for age. Frequency of subjects was calculated for gender Lund and stovner assessment scheme. The p value of less than 0.05 was considered significant. RESULTS: Thiopentone was associated with an adverse response in 76% of patients, compared with propofol in 26% (p<0.01). Head movement, Laryngospasm, inadequate jaw relaxation were more common using thiopentone (p<0.05). The quality of anaesthesia according to patients was significantly higher in the propofol group (Group A, 80%) than in thiopentone group (Group B, 30%). CONCLUSION: Adverse responses in Group A were less than Group B. Propofol, therefore is superior to thiopentone as an induction agent for laryngeal mask airway.

ABSTRACT Discoloration of nonvital teeth is an esthetic deficiency frequently requiring bleaching treatment. The purpose of this study was to evaluate in vitro the effect of bleaching agents on two different cervical barriers in order to minimize or prevent the leakage along the root canal filling in the intracoronal bleaching procedures. Ninety-six extracted human molars were used which were biomechanically prepared, filled and divided into eight groups. The cervical barriers tested were zinc phosphate cement (ZPC) and resin-modified glass ionomer cement (RMGIC) applied (3 mm of thickness) at the cementoenamel junction level. Forty-eight specimens were divided into four groups for each cervical barrier: (1) control group without bleaching agent, (2) a mixture of sodium perborate and distilled water, (3) a mixture of sodium perborate and 10% carbamide peroxide and (4) a mixture of sodium perborate and 35% carbamide peroxide. The bleaching agents were placed inside the pulp chamber for 7 and 14 days, and the access opening was sealed with Cimpat. After 21 days, microleakage evaluation of 2% rhodamine B dye solution at dentin-cervical barrier interface was performed by a stereomicroscope. Data were submitted to Kruskal-Wallis, Dunn's and Dunnett's tests, with a significance level of 0.05. The results demonstrated no statistically significant differences among the control group and the experimental groups for each cervical barrier (ZPC and RMGIC); there were no significant differences among the bleaching agents for the same barrier and RMGIC barrier provided better sealing than ZPC (p < 0.05). Therefore, the bleaching agents demonstrated similar performance when tested for the same cervical barrier and RMGIC barrier provided better sealing than the ZPC barrier, regardless of the association of bleaching agents used.
