Then the bonding procedure followed. Each specimen was tested to failure in shear mode. After debonding, the adhesive remnant index (ARI) was calculated. Results: The mean shear bond strength of the orthodontic brackets when DL was applied after enamel etching was significantly higher than the other intervention groups but lower than that of the control group. SDF groups and DL group applied before enamel etching had the least mean shear bond strength with no statistically significant difference among them. ARI scores for the different groups indicated no significant differences in their distribution frequencies. Conclusions: SDF and DL maintained high shear bond strength to orthodontic brackets. ARI score showed no statistically significant difference in failure site between all groups.","PeriodicalId":305086,"journal":{"name":"Egyptian Orthodontic Journal","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122044158","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}

Angulation of molars and incisors inclination was evaluated from the lateral cephalograms. Anterior dental crowding in upper and lower arches was measured with the help of digital calipers using Little,s irregularity index.

Results: Out of 82 patients 39 were males and 42 were females. Mean age of the patients was 17 + 3 years. Results showed that a positive but insignificant correlation was found between angulation of upper and lower molar and anterior dental crowding. A positive and significant correlation was found between angulation upper 1 st molar and upper incisors inclination. Similar relationship was also determined between lower 1 st molars and lower incisor inclinations.

The purpose of this study was to find out the association between soft tissue facial form and arch form and to find out particular arch form for particular face form. Material & Methods: Three hundred untreated adults (140 males and 160 females) whose initial records were taken for orthodontic treatment were included in this study. Mean age of the patient was 20 ±4 years. The subjects were classified into three different groups on the basis of soft tissue facial form. Soft tissue facial form was determined using Adobe photoshop and each subject was assigned to one of the three group according to facial index. Arch form was determined by the of method occlusogram and arch forms were divided into three groups, tapered, ovoid and square. Results: Regarding the distribution of facial form in the entire sample of 300 subjects, 39 percent of the individuals had mesofacial soft tissue facial form followed by dolichofacial (34%) and brachyfacial (27%). Considering the entire sample size, the most frequent arch form in maxilla was tapered and ovoid in mandible. In dolichofacial individuals the most predominant arch form was tapered while in brachyfacial individuals, square arch form was common. Mesofacial soft tissue facial form shows the predominance of both square and ovoid arch forms. The overall result shows a non-significant association between facial form and arch form. Conclusion: No significant association was found between soft tissue facial form and dental arch form.","PeriodicalId":305086,"journal":{"name":"Egyptian Orthodontic Journal","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123274434","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}

Materials and methods: a clinical trial was held on ten patients were planned to be bonded by full digital indirect bonding tray for upper arch. Intra- oral scanning of each patient was held after indirect bonding to get STL file for evaluation. Vertical brackets positions of total 120 brackets bonded were measured and evaluated. Intra class correlation and Bland Altman plot test were used to assess the accuracy of vertical bracket position of the full digital transfer tray. Results: considering the whole units (120 units), excellent reliability and internal consistency (ICC>0.9) with p value < 0.001* with High level of agreement P value =0.089. For lateral incisors, canines and premolar groups, there was good reliability (0.9> ICC>0.75) with high level of agreement with p value = 0.068, 0.706 and 0.794 in order. An acceptable reliability (0.75>ICC>0.5) was found in central incisors and molars groups.
