A unique arteriovenous fistula, originating from the left main coronary artery and branching to drain into the right atrium and superior vena cava is presented with review of the literature.
Objectives This study aimed to assess the effect of platelet-rich fibrin (PRF) on both bone and supporting tissue healing after surgical removal of impacted lower third molar using the digital panoramic bitewing technique.Patients and methods Twenty patients complaining of a bilaterally impacted lower third molar were included in the study. The surgical treatment plan was removal of bilaterally impacted lower third molar during the same visit under local anesthesia. For the study group, represented by the right side, PRF was prepared from the patient's blood and placed inside the socket and as a membrane covering the buccal bone as well as crestal bone distal to the lower second molar, whereas in the control group (left side of the same patient), nothing was applied at the surgical site and the flap was sutured in a regular manner on both sides. All patients were followed up clinically every week. A digital panoramic bitewing radiographic examination was performed preoperatively and then according to the following schedule: (a) immediately postoperatively (1 week), (b) 3 months, and (c) 6 months.
ResultsThe study group showed statistically significant higher mean bone height and statistically significant lower mean pocket depth than the control group.Conclusion PRF is recommended for alveolar ridge preservation and shortening of the postoperative healing period after surgical removal of impacted lower third molar.
Purpose : To determine the effect of Inherited Cleft Lip and Palate Management on microbial migration in forked lip and palate (CLP) children. Material and methods: Fifteen forked lip and palate children and fifteen standard children (the control group), aged 3 months to 36 months were selected from the out clinic of Faculty of Dental Medicine, Al-Azhar University for Girls. Dribble samples were collected after the breakfast by inserting sterile cotton gauze in the entry from the jaws before and after construction of obturator. Results: The highest (mean±SD) value of log bacterial count (CFU/μl) was found in the cleft patients pre-operatively (5.64±1.06), while post-operatively there was a significant reduction in value (0.60±0.06) (P<0.001). The (mean±SD) value of the log bacterial count (CFU/μl) in the control group (0.59±0.04) was significantly lower than that of the cleft patients pre-operatively (P<0.001), while post-operatively there was no significant difference (P=0.834). The differences were statistically significant for the bacterial count between pre and postoperative periods in children with cleft lip and palate as tested by analysis of variance. Conclusions: Normal children had lower microbial colonization compared with Fissure lip and palate patients, and using obturators decreased the bacterial colony count following treatment of the fissure lip and palate children. Conclusion, Cleft lip and palate patients had more colonization compared with normal children, and the colony count decreased significantly following treatment of the cleft lip and palate children using obturators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
