The patients were selected from those attending outpatient clinic, Oral and Maxillofacial Surgery Department, at the Faculty of Dental Medicine, Boys, Assiut, Al-Azhar University .Clinical examination was made to all patients as: Quality, quantity of the bone, mucosa, contour of the underlying bone and crown to bone relationship. Preoperative panoramic radiographs and cone beam CT were taken for every patient to determine alveolar bone height & width. The change in the implant stability and bone density was measured using cone beam computerized tomography (CBCT) immediately, and after 6 months of healing. All readings were recorded and analysis and statistically. Results: The mean value of horizontal and vertical bone loss in group (1) and group (2) at 6 months showed statistical significant differences between two groups.The mean value of bone density in group(1) and group(2) at months 955.00 ± 52.92 and 670.83 ± 8.01 respectively with statistical significant differences between two groups.

Changing diets and habits are also contributing to the disease’s fast spread in low- and middle-income nations. In many nations, ECC is commonly not treated, which causes discomfort, pain and a negative effect on general health, growth and development, and the quality of life for kids, their families, and even communities. ECC is also a financial, social, and medical burden on world public health. The aim of this study was to identify early childhood caries (ECC) incidence and risk factors among toddlers in Upper Egypt. Subjects & methods: A total of 139 mother-child pairs (60 male, 79 female) were hired at the governorates of Qena and Luxor. In accordance with WHO recommendations, data on ECC and maternal caries were collected. An interview questionnaire was used to evaluate mothers’ socioeconomic level, literacy, and parenting styles. Results: the association between the ECC prevalence and sociodemographic variables shows that there is a significant relationship between ECC and age (p<0.01). Also, there is a significant relationship between ECC and BMI (p<0.05) whereas there is no significant association between ECC and gender i.e. ECC and gender do not appear to be significantly correlated, though. Conclusion: Given the relatively high prevalence of ECC in Upper Egypt, it is critical to review public dental health policies and develop effective strategies to encourage changes in children’s oral health behavior in order to prevent the disease’s spread and worsening. Meaning that preventing the spread and aggravation of the disease depends on public awareness and the development of effective strategies to monitor the oral health of children and their families.","PeriodicalId":136230,"journal":{"name":"Al-Azhar Assiut Dental Journal","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114434051","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}

After bracket placement, three dimensional scans of the casts obtained. Two types of transfer trays were fabricated, and used to bracket transfer to patient’s teeth. After bracket transfer another three dimensional scans of the subjects obtained. The teeth on one model will be then digitally superimposed to the corresponding teeth on the other model.

Subjects and methods : In this investigation, 120 freshly removed human molars were tested. The chosen teeth were randomly divided into two main groups (n=60), with each main group being divided into two smaller groups (n=30) based on the adhesive system (etch-&rinse mode and self-etch mode of application). According to the superficial and deep dentin layers used in the adhesion process, each small group was separated into two even smaller subgroups (n = 15). Each smaller group was divided into three different categories depending on the lengths of storage (24 hours, 3 months, and 6 months) (n = 5). Each tooth was gradually reconstructed using the nanofilled resin composite. The specimens were cut longitudinally in the mesio-distal and bucco-lingual orientations to create resin-dentin beams. For the purpose of assessing nanoleakage, the beam was submerged in silver nitrate. Results : There was no statistically significant difference between groups in terms of the effect of application mode or dentin depth on nanoleakage, however there was a statistically significant increase in median nano-leakage scores from 24 hours to 3 months and 3 to 6 months of storage duration. Conclusion : The use of both bonding chemicals helps to reduce resin composite leakage. Since the self-etch adhesive system excelled total etch in deep cavities, it is advised to use it. While the total etch adhesive method, is advised for use in superficial cavities.","PeriodicalId":136230,"journal":{"name":"Al-Azhar Assiut Dental Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127423235","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}
