“…To ascertain the prospects for enhancement on atypical surfaces, Fonseca et al. [ 19 ] proposed an experimental model that employed metallic straw ( bombilla ) as a substrate onto which LP was deposited. White volcano powder was the most effective in LP development, followed by fluorescent powder and Silk Black volcano powder.…”

Lip print (LP) evidence can be an essential tool for human forensics. LPs have conventionally been developed using substances such as lysochrome dyes, fluorescent dyes, indigo dye, aluminium powder, and silver metallic powder. However, techniques for LP enhancement from various substrates are currently inconsistent and lack standardisation in practice. This review summarises current knowledge on the physical and chemical techniques of LP enhancement, identifies limitations, and provides suggestions for future research on practical applications of cheiloscopy as a forensic tool in criminal justice. Key points The grooves and wrinkles of the human lip establish unique patterns that persist throughout life. Cheiloscopic patterns exhibit discriminatory individual characteristics that may constitute circumstantial forensic evidence. Enhancement techniques for latent lip prints on porous and nonporous substrates can be classified as physical or chemical. Unlike fingerprint, there is a current lack of consistency and/or standardisation on latent lip print enhancement methods in frontline forensic practice.

“…12 , 17 A study about the lip prints on the atypical surfaces has been reported as successful. 30 However, many studies tried to relate the blood group and the lip prints and found negative results. 31 -35 A study correlated the association of the whorl pattern of the lip prints with the cleft lip and cleft syndromes.…”

Aim: Lip prints are unique for any individual. The potential of lip prints as one of the biometric records to determine the identity has been well-recognized. However, studies focused on their reliability by comparing the developed latent lip prints were scarce. This study focused on the reliability of the lip prints for the personal identification by comparing the registered lip prints with the developed latent lip prints made on the porcelain cups. Materials and methods: Samples of 102 subjects (52 males and 50 females) within the age group of 18-30 years were included. Latent and superimposed lip impressions were made on a standard porcelain cup. The latent prints were developed with the fingerprint powder. Then, the lip prints with lip rouge were registered on a transparent adhesive tape. Both the developed latent lip prints and the registered lip prints were photographed with a standard ruler using the digital camera and were compared. The lip prints were classified with the scheme proposed by Tsuchihashi. The statistical analysis was done using the Pearson Chi-square test (IBM SPSS version 20) with a p value of 0.05. Results: The lip prints were unique to any individual irrespective of the gender variation. Their interpretation of comparing the digital pictures confirmed the presence of unique patterns and the possibility of the feature extraction similar to the fingerprints. Type III was the most frequent pattern observed in the study group. Conclusion:We conclude that the lip prints are highly reliable as a biometric record due to their uniqueness. The lip prints have demonstrated enough evidence that is intentionally registered and the developed latent prints were compared, which can be applied as one of the easiest and simplest methods for comparison. Yet, the authenticity of the lip print is in the preliminary level and need more systematic studies to be accepted for the legal disputes. Clinical significance: The study result can strengthen the reliability of the lip prints as an identification tool and discusses the future possibilities of lip print application.

“…For utilizing digital methods, clear lip print photographs in a standardized position are required ( Figure 6(a) ) [ 138 ]. Different substances including aluminum powder, silver metallic powder, silver nitrate powder, plumb carbonate powder, fat black aniline dyer, cobalt oxide, lysochrome dye, or fluorescent dyes can be used for visualization of the latent lip prints [ 139 ]. Aluminum and magnetic powder are the most common substances usually used for identifying and tracing lip prints left in crime scenes [ 140 ].…”

The heavy casualties associated with mass disasters necessitate substantial resources to be managed. The unexpectedly violent nature of such occurrences usually remains a problematic amount of victims that urgently require to be identified by a reliable and economical method. Conventional identification methods are inefficient in many cases such as plane crashes and fire accidents that have damaged the macrobiometric features such as fingerprints or faces. An appropriate recognition method for such cases should use features more resistant to destruction. Forensic dentistry provides the most appropriate available method for the successful identification of victims using careful techniques and precise data interpretation. Since bones and teeth are the most persistent parts of the demolished bodies in sudden mass disasters, scanning and radiographs are unrepeatable parts of forensic dentistry. Forensic dentistry as a scientific method of human remain identification has been considerably referred to be efficient in disasters. Forensic dentistry can be used for either “sex and age estimation,” “Medical biotechnology techniques,” or “identification with dental records,” etc. The present review is aimed at discussing the development and implementation of forensic dentistry methods for human identification. For this object, the literature from the last decade has been searched for the innovations in forensic dentistry for human identification based on the PubMed database.
