Brief summary of the study: English
Antimicrobial mouthrinses are used in many clinical preprocedural situations for decreasing the risk of cross-contamination in the dental setting.The oral cavity is potentially high-risk transmitter of COVID-19. It is important to investigate the efficacy of mouthwash solutions against salivary SARS-CoV-2 in order to reduce the exposure of the dental team during dental procedures. This in vivo study is to evaluate the efficacy of 2 preprocedural mouthrinses in the reduction of salivary SARS-CoV-2 viral load. Saliva samples are collected from COVID-19 positive tested patients before and 5 minutes after mouthwash with 1% Povidone-iodine and 0.2% Chlorhexidine. SARS-CoV-2 rRT-PCR is then performed for each sample. Evaluation of the efficacy is based on difference in cycle threshold (Ct) value.
Brief summary of the study: Arabic
تستخدم محلولات مضادات الميكروبات كتطهير للفم قبل العلاجات السريرية في طب الاسنان. يعتبر تجويف الفم مصدر عدوى عالي الخطورة لـجائحة COVID-19. لذا هناك حاجة ماسة لإجراء تحقيق قائم على الأدلة للتأكد من فعالية محلول لغسول الفم ضد SARS-CoV-2 اللعابي لتقليل التعرض أثناء إجراءالعلاجات في عيادات طب الأسنان. تهدف هذه الدراسة إلى تقييم فعالية غسولي فم في الجسم الحي: 1٪ Povidone-iodine و 0.2٪ Chlorhexidine ضد فيروSARS-CoV-2 اللعابي. يتم جمع عينات اللعاب من مصابين بجائحة COVID-19 قبل وبعد 5 دقائق من غسول الفم. ثم يتم إجراء SARS-CoV-2 rRT-PCR لكل عينة. يعتمد تقييم الفعالية على الفرق في قيمة عتبة الدورة (Ct).
