Twenty-one teeth were unprepared (control), and the remaining teeth were divided into the prepared groups (n = 21), that is, Group H-Files, Group XP-Shaper, Group TruNatomy, and Group Reciproc Blue. All selected teeth were de-coronated perpendicular to the long axis of the tooth by using a diamond-coated disk with water cooling, leaving root segments approximately 16 mm in length. Each group was prepared according to the above file system. Then all roots were sectioned perpendicular to their long axes at 3, 6, and 9 mm from the apex using a diamond-coated disk under a continuous water stream. Each specimen was then checked for the presence of dentinal defects/microcracks.Result: The XP-Endo shaper group had the lowest number of defects (01/21 roots) 4.7%; TN (04/21) 19%, H-Files (04/21) 19%, and RC Blue (05/21) 23.8% had the highest incidence of defects. However, no significant difference was detected among these groups (P > 0.05).Conclusion: The motor-driven root canal instrumentation with rotary and reciprocating files and hand files may create microcracks in the radicular dentine, whereas the XP-Shaper file system produces minimal or less cracks compared to other tested rotary file systems and H-file instrumentation.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140916494","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}

A critical factor for restorative success is the selection of restorative material. Clinicians have tried many restorative materials and techniques to obtain the best performance. The aim of the present study was to evaluate and compare the clinical outcome of a Giomer and Resin modified glass ionomer cement (RMGIC) restoration in NCCL using united states public health service (USPHS) criteria at baseline, 3, 6 and 12 months.Materials and method: Patients from age 25 - 50 years having non-carious cervical lesions on both the sides and requiring restorations were screened. 20 patients were selected and further divided into 2 groups using simple random sampling technique. Group A- Beautifil II restoration using G-Premio bond (n = 10) and Group B- Ketac N100 restoration (n = 10). Restorations were done according to manufacturer's instructions and consequently evaluated at baseline, 3, 6 and 12 months using the USPHS criteria for marginal discolouration, marginal integrity, surface texture, colour match, gross fracture and post-operative sensitivity.Results: Giomer restorations showed better results than RMGIC. There was decrease in alpha ratings in both the study groups i.e., Giomer and RMGIC from 6 to 12 months.Discussion: The overall findings suggest that both Giomer and RMGIC gave satisfactory clinical results when used to restore non-carious cervical lesions. Both the materials can successfully be used since there was no statistically significant difference in the clinical outcome.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140916033","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}

Owing to the resistance and stability against external factors such as trauma and fractures, radiological assessment of the frontal sinus can be a useful indicator for sexual dimorphism. Keeping this in mind, a study was designed to analyse the efficacy of morphometric assessment of the frontal sinus for gender determination in the North Indian population.Materials and method: A total of 300 (150 males and 150 females) lateral cephalograms of the age >20 years were retrieved. The frontal sinus index (ratio of maximum height to depth), area, and perimeter of the same were calculated using Adobe Photoshop software. The results obtained were further subjected to statistical analysis.Result and conclusion: The study yielded an accuracy rate of 75.3% for sex differentiation. The frontal sinus perimeter was a novel parameter which was utilised as a variable in the obtained discriminant equation for sex differentiation. Thus, this cost-effective technique might be useful as an adjunct to assess sexual dimorphism.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140915937","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}

Various procedures have been advocated in the literature to correct dental anomalies, particularly in the aesthetic region, such as tooth discoloration due to fluorosis or dentition spacing due to changes in tooth shape, such as peg laterals.Clinical applications: Veneer are one of the most commonly used treatment modalities in such cases. As the use of ceramics necessitates the use of more opaque restorative materials or different thickness, obtaining adequate results in terms of the final colour of the restoration becomes increasingly difficult. The purpose of this study is to present a clinical case of smile rehabilitation in the anterior region with facets made of lithium disilicate, with the goal of achieving colour uniformity and demonstrating the benefits and achieving smile aesthetics.Takeaway lessons: Technological advancement such as intraoral scanner for impression making have significant improved the success of prosthesis.

An appropriate diet analysis forms the basis for precise dietary advice. Analysis of diet for its cariogenicity is a complex process. Performing a meaningful diet analysis is a challenge in routine clinical practice. Currently, very few tools are available for clinicians to assess children's diet relating to caries risk. The current scientific paper presents a novel index that assesses the cariogenicity and healthfulness of a child's diet objectively and guides the professional to achieve pragmatic diet modification in the prevention of dental caries.Methods: Multi-disciplinary teams with a sample study population were involved in the initial structuring of Diet's Cariogenicity and Healthfulness Index. To obtain cut-off values for cariogenicity of diet, a study was carried out with a sample of 774 children correlating diet diary with caries status. For statistics, the Receiver Operating Characteristic (ROC) curve closest to the ideal of 100% sensitivity and 100% specificity was applied.Results: ROC curve of 22.5 were plotted for diet scores for its cariogenicity. The sensitivity, specificity, and area under the curve of these cut-off values were 70 and 95, respectively.Conclusions: The current scientific paper presents a novel Diet's Cariogenicity and Healthfulness Index that assesses the cariogenicity and healthfulness of a child's diet objectively to guide the professional to achieve a logical diet modification.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140915613","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 recording the periodontal parameters (plaque index (PI), modified gingival index (MGI), probing depth (PD) and clinical attachment level (CAL)), the serum and GCF samples were collected and the levels of caspase-3 and MFG-E8 were estimated using enzyme-linked immunoassay (ELISA).Results: The mean values of PI, MGI, PD and CALs were significantly higher in group III when compared to group II and group I. The mean value of serum and GCF caspase-3 increased with increasing disease severity, whereas the mean serum and GCF values of MFG-E8 decreased with increasing severity of disease. Spearman's correlation showed a strong positive correlation between the serum and GCF levels of caspase-3 and periodontal parameters, whereas serum and GCF levels of MFG-E8 showed a strong negative correlation with the periodontal parameters.Conclusion: The findings of this study are suggestive that the serum and GCF levels of caspase-3 and MFG-E8 could serve as a potential biomarker for the role of apoptosis in periodontal disease.
