Subjects and methods : Study was carried out on sixty primary teeth scheduled for extraction for orthodontic purpose, divided into two equal groups of 30 primary teeth in each one. Group (A): Thirty primary teeth will receive Formacresol pulpotomy. Group (B): 30 primary teeth will receive Pulpotec pulpotomy. All pulpotomized primary molars in the present study were restored with SSCs. All pulpotomized teeth were followed up clinically and radiographically at day 1, 1.5 month, and 3 months. At the 3 months follow-up period, the treated teeth were extracted for histological examination of the pulp. Results: Pulpotec pulpotomy group showed increased children percentage by 10% with pain, tenderness to percussion, swelling, partial loss of lamina dura and widening of periodontal ligament space from 1.5 month to 3 months. Regarding Formacresol pulpotomy group, there was increased children percentage by 30% with pain, tenderness to percussion, swelling, partial loss of lamina dura, widening of periodontal ligament space from 1 day to 3 months and increased children percentage by 3-13% with abscess, fistula, mobility and periapical radiolucency from 1.5 month to 3 months. Regarding histological results, there was a statistically non-significant difference in children percentage. Conclusion: Pulpotec can be used as reliable alternative to Formacresol for the pulpotomy procedures in primary teeth.","PeriodicalId":117944,"journal":{"name":"Al-Azhar Journal of Dental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123269953","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: Ten participants having Class II molar relation with deep overbite with age ranged from 11 to 14 years old were enrolled in the current study. All patients involved in the present study were selected from those seeking orthodontic treatment at different clinical orthodontic centers. Maxillary molar distalization was performed using modified skeletally anchored Hyrax palatal expander. The appliance was activated twice weekly. For each participant, skeletal and dental measurements were recorded from standardized cephalometric analyses before and after molar distalization. Statistical analyses including t-test were performed at a significance level of p<0.05. Results: The maxillary first molars were distalized successfully (6.16 mm) without tipping and Class Ι molar relation was obtained within a period of 6.2 months. Slight extrusion of the maxillary molars was observed which was reflected on the non-significant increase in lower anterior facial height, as the mandibular plane angle was increased by 0.58 0 . A marked improvement of the deep bite was observed. Conclusion: The modified Hyrax can be used as palatally skeletally anchored distalizer to effectively move the maxillary first molars distally. They are effective, minimally invasive and compliance free alternative for molar distalization and hence, molar Class II correction without anchorage loss.","PeriodicalId":117944,"journal":{"name":"Al-Azhar Journal of Dental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131417484","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}

Hence, this study was conducted to evaluate and compare the antimicrobial effect of mouthwashes prepared from pomegranate peel and guava leave extract on oral Streptococcus mutans (S. mutans) count in healthy subjects. Subject and methods: A total of one hundred healthy children aged between 6-12 years were enrolled in this study and equally divided into five equal groups (n=20) according to mouth rinse type used in this study. Group 1 used 2% chlorhexidine (CHX) mouthwash; group 2 used 10 % PPE mouthwash; group 3 used 15 % PPE mouthwash; group 4 used 10 % GLE mouthwash; while group 5 was use15 % GLE mouthwash. Samples of Saliva were collected after mouth rinsing at two-time intervals; immediately after mouth rinsing and 2 hours after rinsing. Mitis Salivarius agar medium was used to determine S. mutans count. Results: The results revealed that S. mutans count recorded a marked significant reduction in all studied groups immediately after mouth rinsing, then S. mutans count was increased significantly in all groups after 2 hrs. The lowest S. mutans count was recorded with the CHX group followed by15 % and 10% PPE groups respectively. While the lowest performance was observed in GLE 15% and 10 % groups respectively. Conclusions: The use of PPE mouthwash has a higher antimicrobial effect when compared to GLE in both concentrations.","PeriodicalId":117944,"journal":{"name":"Al-Azhar Journal of Dental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115089969","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}
