Background: Reprocessing the permanent denture base after try-in is a common procedure in the complete denture fabrication. It is speculated that subjecting polymerized Poly-methyl methacrylate resin again to heat, during reprocessing can induce dimensional changes and a significant loss of intimate fit in the denture base to the tissues, can ultimately reduce the retention and stability of the complete denture. Aim and Objectives: The aim of the study is to evaluate the effect of reprocessing on the accuracy of fit of permanent poly-methyl methacrylate den-ture bases. Material and Methods: A resin edentulous maxillary model was duplicated and a total of twenty casts were poured with type III gypsum product. Group I: Permanent denture bases fabricated with heat polymerized Polymethyl-methacrylate resin. Group II: Group I permanent denture bases with wax rims reprocessed with heat polymerized Po-lymethylmethacrylate resin. Both the group were evaluated for fit using a travelling microscope. Results: Statistical analysis revealed that at each measurement period the mean posterior palatal border openings were not significantly different for processed and reprocessed denture bases. (p > 0.05). Discussion: Reprocessing permanent denture base under controlled laboratory conditions without significant dimensional change, will encourage the clinicians to use permanent record base during jaw relations and try-in. Conclusion: Maxillary permanent complete denture bases were not found to distort significantly as a result of first and second curing cycle. The central part of the posterior palatal border of the denture showed the greatest discrepancy, which was as less as 0.11 to 0.13mm. Reprocessing the perma-nent complete denture base in controlled laboratory conditions will not affect the fit and adaptation.

Keywords: virtopsy, forensic science, autopsy, forensic medicine

   DOI: 10.5005/jsd-3-1-54  |  Open Access |  How to cite  | 


Death is an inevitable part of life and at few occasions scientific examination of bodies after death becomes mandatory. The contribution of Forensic science in achieving this is noteworthy. Forensic pathology is a discipline of Forensic science which deals with pathologic and physiologic changes of a body before and after death wherein autopsy plays a significant role. Conventional Autopsy involves Invasive body opening – the traditional means of postmortem investigation in Humans. Contrary to it is Virtopsy, a minimally invasive emerging technology in the field of Forensic medicine which incorporates Imaging technology that relies on certain fundamental pillars which include - Three dimensional surface scanning 3D/CAD photogrammetry, MSCT- multi slice computed tomo-graphy, MRI- magnetic resonance imaging and Magnetic resonance imaging spectroscopy. Thus serving as a moral boon in the field of forensics is Virtopsy which provides a platform wherein radiologists and forensic clinicians reflect an ethical face in forensic examination after death.

Keywords: biomarkers, gingival crevicular fluid, periodontitis

   DOI: 10.5005/jsd-3-1-59  |  Open Access |  How to cite  | 


The conventional clinical diagnostic aids which were introduced almost half a century ago continues to function as the basis of diagnosis in clinical practice. Recent advances in biochemistry and molecular sciences brought us to the significance of biomarkers as diagnostic aids. This new advance in medical science for periodontal diagnosis will provide immense benefit in managing periodontitis patients. Biomarkers are tell – tale molecules that can be used to monitor health status, disease onset, treatment response and outcome. These biomarkers can be obtained from various body fluids. Obtaining GCF by non invasive method provides an easy and reliable modality in using GCF as potential source for biomarkers This simple and non- invasive nature of GCF sourcing and its high sensitivity assay development have led to the idea of using the GCF biomarkers as diagnostic aids for periodontal diagnosis.
