“…Digital photographs with enhancement tend to exhibit higher positive agreement compared to the other methods for several lip print types. Similar observations were made by Abedi et al in 2022 [ 15 ]. The study suggests promise for the digital photographic method as an accurate and efficient approach for recording lip prints.…”

Background: Direct digital photography for lip print recording is a recent trend, and there is a dearth of systematic research on the analysis of the recorded prints with existing clip print classification systems.Aims and objectives: This study aims to compare the accuracy of the digital photographic method in lip print recording, comparing it with traditional methods, and assessing the suitability of commonly used lip print classification for analyzing lip prints recorded by photographic method.Methodology: A total of 72 participants aged between 20 and 26 were included. The lip print recording process involved photographing the lips without and with lipstick, followed by recording the lip print with cellophane tape on bond paper. The prints collected using the different methods were analyzed and compared for agreement, and the data were analyzed statistically.Results: Inter-observer reliability was high for all methods (>0.800). The distribution of lip print patterns differed across the methods, suggesting a potential influence of the recording technique. The agreement between the conventional method and both digital methods was moderate (kappa=0.449-0.517). The agreement between digital methods with and without enhancement was also moderate (kappa=0.718). Notably, digital photographs with enhancement tend to have a higher positive agreement for several lip print types.Conclusion: Digital photography is a potential method for lip print recording. However, this study highlights the need for the calibration of lip print classification systems for digitally recorded lip prints. Further research is needed to refine the use of digital photography in forensic lip print analysis and to explore its integration with artificial intelligence for biometric identification.

“…But, if on the one hand, it is easy to use, on the other hand, it may not offer the best visualization of the prints. In latent lip prints, for example, the use of alternate light sources, like blue or green light, may allow for better results [ 66 ]. Similarly, other techniques involving filters, polarized filters, contrast, and other imaging software techniques have also offered good print visualization [ 67 ].…”

This study aimed to conduct a systematic review to gather evidence to clarify if cheiloscopy can be used in sex estimation and identify the reasons behind the lack of consensus in the scientific community. The systematic review was performed following the PRISMA guidelines. A bibliographic survey was conducted in PubMed, Scopus, and Web of Science databases, restricted to articles published between 2010 and 2020. Studies were selected according to eligibility criteria, and then the study data were collected. The risk of bias in each study was assessed and applied as additional inclusion or exclusion criteria. The results of the articles eligible for analysis were synthesized using a descriptive approach. In the 41 included studies, several methodological flaws and variations between studies that contribute to the discrepancy in results were identified. The data gathered allowed us to conclude that there is no strong scientific evidence to support the use of cheiloscopy in sex estimation, as there is no specific pattern for each sex, which reduces the criminalistic interest of cheiloscopy in estimating this parameter.

“…As a result, if a suitable method cannot be developed, the lip print approach can be utilized as a substitute for other forensic investigative methods, and lip prints have the potential to be a supporting tool in identification. This statement from Karki 22 is backed up by Abedi et al 23 , who claim that lip prints aren't the same as fingerprints because there are still flaws, such as the lack of validation and quality in defining specific lip print procedures. Lip prints, on the other hand, can sometimes help provide answers and act as extra evidence in relation to the events being investigated.…”

Background: Many researchers have conducted studies oflip prints to aid in human identification. The distinctiveness of the lip print pattern will be a distinguishing feature from one person to the next.Purpose: This study analyzes the dominant types and patterns of lips print in males and females.Results: Most males--7 research out of 20--were type III lip print pattern, and 6 out of 20 belong to the type II lip print pattern. Femalesmainly were typed II pattern-11 out of 20, and type I pattern-7 out of 20. Conclusion:When the patterns are type I or type III, the sex of the individual can be easily identified; however, when the pattern is type II, the individual could be either a male or a female, with a higher probability of being a female. Other forms of identification should be available to support sex identification in this circumstance.
