Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

This study is motivated by the issues found in observations at school, where the daily teaching activities carried out by teachers show that; teaching and learning activities are classical, the teacher only stands or sits in front of the class, the direct relationship between the teacher and students is rare, and students tend to behave passively, such as coming, listening, reading and writing. To overcome this issues, the researchers conducted a research by applying a three-step type of cooperative learning model interview in learning mathematics in the class. The purpose of this study is to reveal the activities and learning outcomes of students after applying the three-step interview type cooperative learning model. From the results of the study it was found that the learning activities of students during the application of the three step interview cooperative learning model increased at each meeting. Thus it can be concluded that the mathematics learning outcomes of students with learning by applying a three-step interview type cooperative learning model is better than those who do not apply the techniques.

Abstractwas to assess efficacy of Tadalafil alone versus Tadalafil plus Pentoxifylline in the treatment of erectile dysfunction by using self administered IIEF-5 questionnaire.Two hundred and thirty seven patients presenting with ED at andrology OPD were evaluated for ED by a self administered IIEF (International Index of Erectile Function) questionnaire. Patients were systematically randomized by computer generated random table into two groups groups namely, group A: Tadalafil only group, group B: combination of Tadalafil + Pentoxifyl-line. All the patients were re-assessed by IIEF-5 questionnaire after 8 weeks of medical therapy. Statistical analysis was performed using student’s unpaired t-test, paired t-test, chi square test. p-value < 0.05 was considered statistically significant.Two hundred and thirty seven patients were included in the present study, in group A: 92 patients (78.6%) showed improvement in their IIEF score after 8 weeks of tadalafil treatment. While in group B, overall 104 patients(86.6%) showed improvement after combination of Tadalafil and Pentoxifylline. There was a statistically significant difference of percentage change in IIEF score was seen in group B (group A 90.7±15.2%, group B 95.6±13.4%; p value – 0.014). We found this difference even more statistically significant in patients with severe ED (group A 72.7±47.2%, group B 132.3±54.3%; p value – 0.000). There was no significant difference in between the two groups with regards to occur-rence of side effects.Both tadalafil and combination of Tadalafil + Pentoxifylline improve erectile function in patients of ED. Patients with severe ED showed much significant improvement in erectile function with combination therapy.

ABSTRACT Objective To compare the level of satisfaction in the use of wraparound Hawley and thermoplastic maxillary retainers. Materials and Methods The study sample included 70 orthodontic patients (24 males and 46 females), who were in the retention stage (mean age = 20.80 years). All patients wore the two types of maxillary retainer for 1 month each, along with a 3×3 fixed mandibular retainer. After the use of each retainer, the patients responded to a questionnaire evaluating the level of satisfaction with their use of the maxillary retainer. Intergroup comparison was performed by independent t tests. Chi-square test was used to evaluate preference for the type of retainer by gender. Results The thermoplastic retainer was better for swallowing and the wraparound Hawley appliance was better for hygiene and durability. The other factors evaluated (adaptation, speech, comfort, esthetics, satisfaction, and fitting) did not show significant differences between the retainers. There was also no significant difference in preference for the appliances. Conclusions Regarding the overall satisfaction and the preference, there was no difference between the wraparound Hawley and thermoplastic retainers. The wraparound Hawley appliance was better in hygiene and resistance than the thermoplastic retainer; and the thermoplastic appliance was better than the wraparound Hawley for swallowing fluids and saliva.
