Materials and methods: A total of sixty intact upper central incisors were randomly split into four groups (n=15 each) according to the antioxidant used and all groups were bleached using gel containing 40% hydrogen peroxide (HP): G1 (control group): Bleaching with no antioxidant. G2: Bleaching followed by 5% grape seed extract solution for 10 mins G3: Bleaching followed by 5% green tea extract solution for 10 mins G4: Bleaching followed by 10% sodium ascorbate solution for 10 mins. The assessment of free radicals for each group was evaluated by colorimetric method at three-time intervals; baseline, after 24 and after 48 hrs. Results: Regarding effect of antioxidants on free radical clearance at different time intervals , results of this study showed that there was statistical substantial disparity between all groups at all time intervals. The greatest mean percentage change was recorded for sodium ascorbate, followed by green tea, then grape seed extract whereas the least value was recorded for the control. Conclusion: All the antioxidants employed in this study were capable of removal of free radicals after bleaching. It was concluded that, sodium ascorbate showed statistically significant decrease in free radicals after tooth bleaching when compared to natural antioxidants.","PeriodicalId":7493,"journal":{"name":"Al-Azhar Dental Journal for Girls","volume":"531 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80175765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subjects and Methods: about 50 Egyptian patients were selected in this study who were referred to the department of oral medicine, periodontology, oral diagnosis & radiology, Faculties of Dental Medicine, Al-Azhar university for panoramic or cone beam examination for various dental purposes. Patients were divided into two groups (25 patients each). First Group was subjected to panoramic examination and the second one was subjected to cone beam examination. The systems used were a Planmeca Viso CBCT and Orthopantomogram OP-100 panorama. Assessment of the patient radiation dose was done by thermoluminescent dosimeter (TLD) on the patients. The absorbed radiation dose is then recorded. Data was then analyzed, and statistical calculations were performed. Results: The absorbed radiation skin doses ranged between (130 µGy, 2817.8 µGy) in panorama and (327.99 µGy, 11994 µGy) in CBCT for one exposure. When digital panoramic unit and CBCT were compared, panoramic imaging is 25-37% of CBCT. Parotid gland and oral mucosa absorbed the greatest radiation dose for all panoramic and CBCT patients. CBCT radiation doses are considerably higher than those of digital panoramic unit. Conclusion: The prospective benefits of CBCT in maxillofacial disciplinary are undoubted; but, it is important that their use be totally justified above conventional technique before they are done.","PeriodicalId":7493,"journal":{"name":"Al-Azhar Dental Journal for Girls","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88971765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
