CERVICOGENIC HEADACHE AMONG DENTISTS WORKING IN LAHORE MEDICAL AND DENTAL COLLEGE

Background and Aim: Headache is a very common condition worldwide. Cervicogenic headache is a secondary type of headache. Dentistry requires both, the concentration and precision and dentists have to work in constricted zones for extended period of time so it is important to evaluate headache among dental population. The objective of this study was to screen Cervicogenic headache among dentists working in Lahore Medical and Dental College, Lahore. Methodology: The Descriptive Cross-sectional study, of 6 months duration, was conducted on 125 dentists. The data was collected from Lahore Medical and Dental College, Lahore.  Non-Probability convenience sampling technique was used. Dentists working for at least 2 years and more than 5 hours daily, with the known cases of headache were included and those who were diagnosed with any other condition that cause headache like acute sinusitis, High blood pressure etc. were excluded. Data was collected by using cervical Flexion Rotation test whose validity is 0.81. Data was entered by using Statistical package for Social Sciences (SPSS) version 21 and the same software was used for data analysis. Results: The findings showed that, out of 125 dentists, 36.8% (n=46) were male and 63.2% (n=79) were female and cervical flexion rotation test was positive in 30.4% (n=38) dentists. Conclusion: This study concluded that cervicogenic headache is present in 30.4% dentists working in Lahore Medical and Dental College.

Effect of Samarium Additions on Shape Memory and Thermomechanical Behavior of Iron Based Shape Memory Alloys

In the present work, a comparative study of the shape memory and thermomechanical behavior of four alloys containing different amount of samarium have been carried out at a strain rate of 0.08x10 -6 s -1 . After hot rolling, annealing and solution treatment, the alloy samples were tensile deformed at room temperature from 1% to 5% and were then recovered at 600̊C for 20 minutes repeatedly for six times to complete six training cycles. It has been found that the addition of samarium strengthens the austenitic matrix, increases the c/a ratio and reduces the grain size. It has been noticed that the addition of samarium (0.64 wt. %) improves the shape memory effect when the alloys were strained from 1% to 5%. This improvement in shape memory effect presumably can be regarded as the increase in strength, increase in c/a ratio and absence of ά (martensite). It has been further noticed that when samarium contents are gradually reduced from 0.64 % to 0.21% the shape memory effect decreases. The decrease in shape memory effect by the decrease in samarium contents can be attributed to decrease in strength, decrease in c/a ratio and formation of ά (martensite). It has been further noticed that the shape memory effect decreases with the increase in amount of strain. It is found that thermomechanical treatment (training) results in improvement of shape memory effect and has a significant influence on mechanical parameters like proof stress (σ 0.002 ), critical stress (σ 0.0008 ) and strain hardening exponent. The improvement in shape memory effect by thermomechanical treatment can be regarded as the effect of reduction in the values of proof stress and critical stress during training which facilitates the formation of ε (martensite). It has also been noticed that excessive training may result in the formation of ά (martensite) due to continuous softening of the alloy during training, thus degrading the shape memory effect. Finally, it has also been noticed that the addition of samarium increases the values of proof stress, critical stress and strain hardening exponent. Although the addition of samarium increases the values of proof stress, critical stress and strain hardening exponent yet it has not an adverse effect on shape memory effect.
