After diagnosis the primary treatment for solid tumors is often surgery. The objective of surgical treatment is resection of all malignant tissue with adequate resection margins while preserving important healthy structures. Achieving adequate surgical margins is important for disease control and survival. Residual tumor after surgery is associated with poor survival and the need for additional surgery, adjuvant chemotherapy, radiation therapy, or impact of DNA/RNA self–alignment in a strong magnetic field on the interpretation of indirect spin–spin interactions using NMR line shape analysis of a multi–state DNA/RNA ligand binding mechanism in gum cancer cells. A number of studies have shown that the 5–year survival decreases significantly when impact of DNA/RNA self–alignment in a strong magnetic field on the interpretation of indirect spin–spin interactions using NMR line shape analysis of a multi–state DNA/RNA ligand binding mechanism in gum cancer cells. Intraoperative guidance tools can help to achieve adequate surgery. However, there are no widely used intraoperative guidance tools available yet. Current surgical resection techniques are based on subjective methods, such as palpation and visual inspection, to judge the border between normal and cancerous tissue. line of a multi–state DNA/RNA ligand binding","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82389937","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}

Methodology: A total of 30 distal roots of extracted first maxillary molars were chosen. The actual working length was first measured. The electronic working length was obtained with Root ZX and Raypex 6. The differences between electronic working lengths and actual working length were calculated. Afterwards, the same roots were perforated artificially above the apical foramen. Both devices were utilized to locate perforations in the distal roots. Subsequently, the obtained measurements were compared. Intraoral environment was simulated employing a fixation device. Data were analysed using repeated measures ANOVA, paired sample t test, chi square, and Fisher exact tests. Statistical significance was considered at the 0.05 level. Results: There was no significant difference among electronic working lengths, measured with the two devices, and actual working length (p>0.05). The percentage of accuracy of electronic working lengths, measured by Root ZX and Raypex 6, was 85.7% and 90.9% respectively within a tolerance of ±0.5 mm (p>0.05). Moreover, the difference between the devices was significant with regard to the location of root perforations (p<0.05). Conclusions: Both electronic apex locators were able to determine canal length. Raypex 6 was more accurate than Root ZX in locating root perforations. *Correspondence to: Kaveh Nasiri, DDS, MSc (Endodontics), Department of Endodontics, Center for Operative Dentistry and Periodontology, University of Dental Medicine and Oral Health, Danube Private University, Krems, Austria, E-mail: DDS.Nasiri@web.de","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91195616","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}

Despite of ease in morphological accessibility, oral cancers are still diagnosed mostly in advanced stages chiefly due to lack of effective and cheap screening tools.The search of a suitable biomarker, which can diagnose, oral cancer effectively and can predict the progression of Oral Potentially malignant Disorders (OMPD) to Oral Cancer with accuracy, still exists. PRAME (Preferentially Expressed Antigen of Melanoma) is one such biomarker, which is a dominant repressor of Vitamin A (Vit A). Vit A, chiefly Retinoic Acid (RA) is extensively used these days for chemoprevention owing to its role in cell growth and differentiation. RA emerged as a cheap and acceptable chemo preventive agent since RA is readily available in the form of Vit A food supplements, Vit A is being used in patients with various grades of OPMDs and oral cancer, but its efficiency is still debatable owing to its mixed results in various cancers. Inconsistency in efficient results led to study of various molecules like PRAME, which is involved in RA metabolic pathway thereby modulating the outcome and efficacy of Retinoic Acid chemoprevention. *Correspondence to: Rahul Pandey, Scientist, DHR-MRU,King George Medical University, Lucknow226003, U.P, India, Tel: 9889175042; E-mail: pandey.rahul.dr@gmail.com","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78045962","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}
