A Questionnaire-Based Study to Assess Knowledge and Awareness Regarding Cheiloscopy as a Forensic Odontology Diagnostic Tool Among Dental Professionals

Abstract

Background: The lips are covered with grooves and wrinkles, which form a characteristic pattern called a "lip print. The study of lip prints is called cheiloscopy. Searching for lip prints in the crime scene investigation helps in personnel identification and establishment of the true nature of the crime.Objective: This study aimed to assess the knowledge and awareness of cheiloscopy among dental undergraduates, postgraduate students, and general dental practitioners. Materials and methods:This cross-sectional observational, descriptive, survey-based study was conducted among 320 dental professionals, which included undergraduates, graduates, postgraduate dental students, and general dental practitioners aged between 18 and 32 years. A self-administered structured questionnaire written in English and Arabic was distributed to all willing participants. The questionnaire included knowledge and awareness-based questions along with demographic details of the participants. The Chi-square and Fisher's exact tests were applied to find out the association between the characteristics of the study participants and their knowledge and awareness of forensic odontology. A p-value of 0.05 was considered significant for all the statistical tests using IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.Results: A total of 320 dental professionals completed the survey. The majority of participants (55.3%) were males (and 14.4% were females) between the ages of 23 and 27. Most of the participants were general dental practitioners (36.9%), followed by undergraduates (26.3%), graduates (8.8%), and postgraduates (18.1%). Cheiloscopy, the study of lip prints, was known to 36.6% of the participants. Whereas the majority of the participants (63.4%) were not aware of it. Postgraduate (46.7%) students had more knowledge as compared to undergraduates, graduates, and general dental practitioners. About 81.6% of the participants were not aware of the classification of lip prints by Tsuchihashi and Suzuki. Conclusion:Overall, there was a lack of knowledge and awareness of cheiloscopy among all study participants, although they had good knowledge of forensic odontology. Compared to undergraduates and graduates, postgraduate dentistry students showed a greater level of cheiloscopy knowledge and awareness. Comparatively to students, general dentists, however, lacked understanding and awareness of cheiloscopy. This condition, however, can be improved if necessary steps are taken to make forensic odontology a part of the dental curriculum in Saudi Arabia.

Awareness of Forensic Odontology in a Sample of Dental Physicians in Upper Egypt

“…The lack of forensic odontology in the undergraduate curriculum, as declared by most participants, may be the blame for this. Abdul et al (2022) reported similar findings, noting that forensic odontology was not included in Saudi Arabia's undergraduate curriculum. Isher et al (2019) discovered that, in contrast to the current finding, most of the questioned dentists in Punjab, India, had a forensic odontology course during their undergraduate studies.…”

“…The distinctive pattern of lip prints are made by the interaction of lip's external surface peaks and depressions. Lip prints on clothing, mugs, glasses, and cigarettes may be seen at the crime scene (Abdul et al, 2022).…”

Knowledge, Attitude and Perception Regarding Artificial Intelligence in Periodontology: A Questionnaire Study

“…The study's findings revealed that the response rate reached 78%, with the majority of the participants being female (68%). This observation can potentially be attributed to the higher number of females pursuing dentistry as their chosen profession, with a significant portion opting for higher education [ 11 , 12 ]. The attitude, knowledge, and perception of periodontists are important for the successful performance of AI in periodontal healthcare, as scant information has been reported to date.…”

Advancements and Challenges Forensic Odontology and Anthropology: Applications for Identification in Saudi Arabia

“…As Another Saudi study published in 2022 regarding the awareness of cheiloscopy had determined that out of 320 dental professionals, cheiloscopy was only known to 36.6% of them and 63.4% did not know of its existence. Summarizing that there is a lack of awareness, understanding and knowledge of cheiloscopy among Saudi dental professionals (Abdul et al, 2022a). Stating that 74.62% of the participants were willing to register in a national dental registry if one was to be established in Saudi Arabia (Aboalshamat et al, 2021) .…”

“…The limited awareness and training among dental professionals (Abdul et al, 2022b) underscore the urgent need for educational initiatives and standardized guidelines to bridge these gaps. Moreover, the findings regarding public awareness and willingness to participate in a national dental registry reflect a growing recognition of the importance of forensic odontology in Saudi Arabia.…”
