Background:Infection prevention and control measures are critical to prevent the possible spread of Middle East Respiratory Syndrome-coronavirus (MERS-CoV) in healthcare facilities. Therefore, healthcare workers should be aware of all procedures concerning prevention of and protection from MERS-CoV.Objective:The aim of this study is to improve the knowledge of the dental students and evaluate their awareness about MERS-CoV.Materials and Methods:A questionnaire was made according to MOH information and 200 dental students (Al-Farabi Colleges, Jeddah) were interviewed to evaluate their knowledge about MERS-CoV.Results:More than half of the dental students (54%) interviewed had good knowledge about the etiology, symptoms, and treatment of MERS-CoV. Measurements for infection control and protection were also known (79%). The sources of information for the students were: college (27%), MOH (25%), media (24%), and social community (23%), while 17% of the students interviewed had no idea about it.Conclusion:Dental students had good knowledge about MERS-CoV. However, more information still must be provided by MOH and college for the medical staff.

The aim of this study was to evaluate the clinical reliability of the Pederson index in preoperative assessment of the difficulty of surgical removal of impacted mandibular third molars. Pederson index was found to be unreliable predictor of true difficulty with low sensitivity and specificity. A new index (Kharma scale), which takes into consideration the anatomical form of tooth roots, is proposed and evaluated both pre- and postoperatively. The results of the evaluation indicate that the new estimating index is more reliable and accurate measure than Pederson scale.

The morbidity and mortality associated with being overweight or obese have been known to the medical profession to be related with an increased risk of associated diseases.
