The occurrence of invasive fungal respiratory superinfections in patients with COVID-19 has gained much attention in the post-COVID era. The elucidation of invasive fungal sinusitis with osteomyelitis as a rare aggressive infection that requires prompt diagnosis and treatment to prevent fatal consequences has been noteworthy. Cone-beam computed tomography findings in those patients are central to early diagnosis and management.

Water bodies play a very important role in maintaining and restoring the ecological balance, but they are one of the most threatened habitats in the world. Anthropogenic intervention is changing the regimes of wetlands almost everywhere particularly in the developing countries. Gorakhpur District is dotted with many big and small flood plain-related water bodies like rivers, streams, tanks, dead arms, oxbow lakes, etc.

Aim: To compare the uniqueness of human dentition in both orthodontically treated and untreated populations and evaluate the reliability of bitemark analysis.

Materials And Methods: A total of 1464 maxillary and mandibular casts were fabricated from orthodontically treated and nontreated population. After careful examination of the study teeth, 326 nontreated maxillary cast (Group 1), 333 nontreated mandibular cast (Group 2), 336 orthodontically treated maxillary cast (Group 3), and 320 orthodontically treated mandibular casts (Group 4) were selected for the analysis.

Background: Oral submucous fibrosis (OSF) is an insidious, chronic, disabling disease, in which there is lack of perfusion due to reduced level of the vasculature and this is said to be responsible for the epithelial atrophy seen in OSF. The degree of vasculature of the affected mucosa and its effects on the epithelial thickness remains controversial till date.

Aims: This study attempts to analyze the role of angiogenesis in OSF and its progression using vascular endothelial growth factor (VEGF) and CD34 markers.

Introduction: Bite-mark analysis has proven its advantage as an important forensic tool in the past but also has a few limitations to it. To enhance its utility in forensic odontology in this study we have coupled it with Berry's Index (BI) which is an index used to select anterior teeth in prosthetic practice.

Aims And Objectives: This study was attempted to analyze the applicability of BI in identifying an individual.

Introduction: Gender estimation from dismembered human body parts and skeletal remains in cases of mass disasters, explosions, and assaults cases is an imperative element of any medico-legal investigations and has been a major challenge for forensic scientists.

Aim: The aim of the present study was to estimate the gender by using index and ring finger length ratio, hand and foot index along with the correlation of both the hand and foot index to determine the vital role of all the indices in establishing gender identity.

Materials And Methods: A descriptive cross-sectional study was done on 300 subjects (150 males and 150 females).

Diverse environmental and physiological factors are known to induce the transcription of a set of genes encoding special protective molecules known as "molecular chaperones" within our cells. Literature abounds in evidence regarding the varied roles; these "guides" can effectively perform in our system. Highly conserved through evolution, from the prokaryotes to the eukaryotes, these make perfect study tools for verifying their role in both the pathogenesis as well as the therapeutics of varied neurodegenerative, autoimmune and potentially malignant disorders and varied cancer states.

Forensic facial reconstruction can be used to identify unknown human remains when other techniques fail. Through this article, we attempt to review the different methods of facial reconstruction reported in literature. There are several techniques of doing facial reconstruction, which vary from two dimensional drawings to three dimensional clay models.

Background: Oral lichen planus (OLP), a well-known mucocutaneous lesion has been the center of debate regarding its obscure etiopathogenesis. Recent highlight has been placed on the role of autoimmunity and a sect of constitutional molecules, the native chaperones HSP70, proposed to be important in the onset and progress of disease.

Aim: To substantiate a potential role of HSP70 in the pathogenesis of oral lichen planus.
