Background: The dermatoglyphics have been used in several researches for predicting various pathologies of oral cavity like periodontitis, dental caries, impacted teeth, mal-occlusion, developmental defects such as cleft lip and palate, and potentially malignant disorders. Impacted teeth may be associated with various pathologies such as caries, pericoronitis, dentigerous cysts, and keratocystic odontogenic tumors; therefore, predicting impacted teeth through dermatoglyphic patterns can help in diagnosis and future treatment planning of such event.
Aims And Objectives: The aim and objective of the study were to evaluate and compare various dermatoglyphic patterns in the patients with the impacted maxillary and/or mandibular third molar (group 1) and patients having erupted maxillary and/or mandibular third molar (group 2).
Materials And Methods: This study comprised totally 300 patients, which were divided into two groups, according to erupted or impacted maxillary and/or mandibular third molar visiting outpatient department, who fulfilled the selection criteria for the study. After a comprehensive clinical examination, dermatoglyphic patterns were recorded from the same individuals. Panoramic radiographs were taken to confirm the diagnosis. Data collected were entered in the spreadsheet and analyzed. For all tests, value was set at <0.05 and was considered statistically significant.
Result: There was statistical significance noted in frequencies of whorl pattern in patients of group 1 and loop pattern in patients of group 2.
Conclusion: This study concluded that dermatoglyphic patterns can be used to assess the prevalence of impacted wisdom teeth.

Background And Objectives: Globally, the prevalence of diabetes and dental caries has been soaring high in recent times. There is a constant effort in the scientific community to develop a reliable and economic early predictor which can serve the purpose of mass screening of genetically vulnerable populations. The present study attempts to evaluate the different types of lip prints and finger prints in diabetes mellitus and dental caries and to see association between the most common diseases (diabetes mellitus and dental caries) if any.

Purpose: Emerging therapeutic strategies for Kabuki syndrome (KS) make early diagnosis critical. Fingerprint analysis as a diagnostic aid for KS diagnosis could facilitate early diagnosis and expand the current patient base for clinical trials and natural history studies.
Method: Fingerprints of 74 individuals with KS, 1 individual with a KS-like phenotype, and 108 controls were collected through a mobile app.
In 2022-2023 the Defence Science and Technology Laboratory (Dstl) designed and conducted a two-part fingerprint Collaborative Exercise (CE). The CE focussed on fingermarks contaminated in blood as they provide a complex scenario for forensic units and it involved both fingermark visualisation and comparison elements. Participants were requested to treat the exercise as a major crime submission following internal protocols and were invited to provide comments relating to how the marks were deposited (if appropriate).

Carbon dots (CDs) are zero-dimensional carbon nanomaterials that have been subject of considerable interest due to their remarkable electronic and optical characteristics. Their adjustable properties have gathered attention in different fields, including biological sensing, drug delivery, photodynamic therapy, photocatalysis, solar cells, and latent fingerprint development. In forensic science, the frequently reported outstanding photoluminescence behavior and biocompatibility of CDs are particularly important.

Perceptual expertise is typically domain-specific and rarely generalises beyond an expert's domain of experience. Forensic feature-comparison examiners outperform the norm in domain-specific visual comparison, but emerging research suggests that they show advantages on other similar tasks outside their domain of expertise. For example, fingerprint examiners not only outperform novices in fingerprint comparison, but also in face comparison.
