ABSTRACT
To determine the prevalence of self-reported tooth discoloration amongst the study sample, to assess the relationship between tooth discoloration and selected risk factors. A cross-sectional study was conducted between March-July, 2014 including 200 students studying in Gulf Medical University, Ajman. A stratified random sampling method was used to recruit the participants. A self-administered questionnaire was used as a tool, tooth discoloration [irrespective of being internal or external] was self-reported. Data was analyzed by SPSS vesion20. Association between tooth discoloration and independent factors were tested by X[2] test with a significance level of 0.05. The frequency of tooth discoloration amongst the participants was 43.5%. Higher frequencies of tooth discoloration was found in age group 20-24 years [49.6%, p value= 0.054] and was found more in BPT students [75%, p value= 0.001], Smokers were more effected when compared to nonsmokers [62.7% vs 35.5%, p value= 0.001]. Frequency of coffee consumption was also found to have an association with discoloration, as 60% of students who drank coffee more than twice a day reported tooth discoloration. Self-satisfaction displayed a divide in opinion amongst participants with discoloration, with only 48.3% of the 87 students professing dissatisfaction with the current esthetic appearance of their teeth. Finally, it was found that out of the entire sample only 33 students [37.9%] had previously sought for cosmetic improvements of their smile by undergoing tooth bleaching. Tooth discoloration is common among college student with a prevalence of 43.5%. Significant associations were noticed between tooth discoloration and smoking, academic program. Only 33 students [37.9%] had previously sought for cosmetic improvements of their smile by undergoing tooth bleaching

Coronary Artery Disease [CAD] plays a major role in mortality worldwide. Thus there is a great challenge before clinicians to find out safe and effective therapy. There are some Unani drugs like Badranjaboya, Balchar, Jadwar and Arjun whose efficacy is mentioned in Unani literature without any known side effect. A clinical trial of these drugs on 60 patients of ischaemia was carried out which were selected on the ground of clinical presentation, ECG findings and ventricular dyskinesia in 2D, M-mode echocardiography. Drugs were given in the powder form orally [10 gm powder in two divided doses], study duration was set for two months and efficacy of the formulation was evaluated following modern parameters
