Lip print
Natural dyes (vermilion and indigo) and lysochrome (Sudan black)The three dyes were applied to visible and latent lip prints and compared using statistical analyses.All dyes showed comparable results for creating visible and latent lip prints.[144]/2010
CheiloscopyThe lip print of a study group comprising 200 subjects was compared.Lip prints are represented to be individually unique enough for personal identification.[132]/2011
Lip patternsA pilot study was performed to evaluate the correlation of lip prints, mandibular canine index (MCI), and fingerprint methods for gender estimation.These three specific parameters showed no statistically significant correlation.[123]/2011
Cheiloscopy, palatoscopy, and odontometricsLip pattern impression and odontometric measurements were performed for each subject.The findings confirmed the uniqueness of lip prints that can provide a more reliable sex prediction.[133]/2014
Lip printsAn experimental model of latent lip prints was provided, photographed, preserved, and analyzed.The lower lip print revealed a better definition.[139]/2014
Cheiloscopy using lysochromeLatent lip impressions were developed using lysochrome.Lysochrome-printed lip patterns can be preserved in a digital database and are a potential tool for sex determination.[145]/2015
Lip prints and lip competenceThe lip prints were obtained, and the lip competence was determined and recorded.Lip prints and competence showed specificity for individuals, races, and ethnic groups.[137]/2015
Cheiloscopy and dactyloscopyThe lip impression, fingerprints, and personal characters of subjects were recorded, and their correlation was statistically analyzed.The findings showed a fair correlation among the lip/finger traces and gender/personality of subjects suggesting it as an adjunct in forensic investigations.[124]/2015
Cheiloscopic patternsLip prints of subjects were classified based on the Tsuchihashi method, and gender estimation was conducted according to Vahanwala et al.Cheiloscopy was suggested as a promising supplementary tool for sex determination; however, further standardized studies were suggested.[131]/2015
Lip prints from different racesLip prints of 3 ethnic groups were recorded and evaluated.The 3 races significantly differed in lip patterns.[140]/2016
Lip outline patternsLip outline patterns were impressed on the proforma sheet and analyzed.Lip outline patterns are represented to be individually unique.[146]/2016
Morphologic patterns of lip printsThe lip groove patterns of subjects were categorized based on the Tsuchihashi method.Lip groove patterns showed significant gender dimorphism in the Croatian population.[10]/2016
Lip and fingerprint patternsLip prints and right thumb impressions were recorded and analyzed.Both these parameters showed to be reliable personal identifiers.[142]/2016
Lip printThe obtained lip prints were classified into six classes regarding the vertical, horizontal, and intersecting lines.The outcome revealed no significant correlation between the lip prints and subject identities.[136]/2017
CheiloscopyLip prints and right thumb impressions were recorded and analyzed.Both lip and fingerprints were recognized as helpful for sex estimation.[127]/2017
Oral landmarksSystematically review the applications of oral landmarks such as bite marks, dental records, and palatal rugae, in forensic identification investigations.Prosthetic dentistry was discussed to be a significant aid for forensic purposes.[128]/2017
Lip print patternsExamine the gender dimorphism in the lip pattern over time using digital photography.The efficiency of lip prints in forensic investigations for individualization was emphasized.[126]/2017
CheiloscopyThe lip print records were categorized and analyzed according to Suzuki and Tsuchihashi methods.Type I lip pattern was shown as the most frequent type.[130]/2017
Lip prints and palatal rugae patternThe records of lip prints and palatal rugae were analyzed based on the Kapali et al.’s classification method.Lip print (cheiloscopy) is shown to be a more reliable gender identifier than the palatal rugae pattern (rugoscopy).[141]/2018
Lip print patternsAn algorithm was developed for mass imaginary record processing.The algorithm facilitated the analysis but lip grooves, and gender showed no association.[129]/2018
Lip print patternsLip print records were collected via a purposive nonrandom sampling method and photographed using a digital camera and analyzed by Photoshop.Lip prints were shown to be inheritable and various among a population from a single race.[138]/2019
Bite mark
Overlay generation methodsOverlays were prepared using manual, photocopy, and computer-assisted methods, and the results were compared.The computer-assisted method was the best one.[151]/2013
Bite marks on dental casts, bitten objects, and foodstuffsThe bite marks were recorded using x-ray and cone-beam computed tomography (CBCT) and visualized/analyzed by InVivo5® software.CBCT was proved to be an important aid for forensic applications.[157]/2013
Bite mark characteristicsA case study was conducted on three crimes with common offenders describing the locations and characteristics of the bite marks.Bite mark analysis was proved to be an important aid for forensic investigators.[35]/2014
Topographic overlaysOverlays were generated using the envelopment technique and compared.The third and fourth cuts were the most reliable sections to be studied.[160]/2015
Bite mark overlaysOverlays were produced by different methods (e.g., casts, wax impressions, radiopaque wax impression, and xerographic method) and compared.Every method showed its specificities for bite mark analyses and can be helpful depending on personal preference.[156]/2016
Bite mark evidenceThe article debated the legal requirement of bite mark evidence scientifically discussed its future.The article reached an unsuccessful outcome for bite mark evidence.[158]/2016
Bite mark evidenceThe opinions of forensic odontologists on bite mark cases were surveyed at the beginning and after 8 weeks.The results suggested that bite mark evidence is less reliable than other oral landmarks.[150]/2016
Bite mark modelsPositive replicas of bite marks were prepared using computer-assisted modeling methods.The used computer-assisted method is shown to be simple, reliable, reproducible, and cheap.[152]/2018
Berry’s index (BI)BI was analyzed in a 300-subject study population.BI was suggested as a potential aid for bite analysis and facial proportion determination.[147]/2018
Bite mark evidenceBite marks were recorded using two materials (styrofoam and wax sheet), analyzed for 3 days, and compared.Both materials were proper and reproducible, but casts on styrofoam altered after 3 days.[148]/2018
Bite mark on foodstuffs and inanimate objectsSystematically review the studies analyzing the validity and judicial acceptance of bite marks on foodstuffs and inanimate objects using Daubert rulings.Because of the vulnerability of forensic procedures, high scrutiny in evaluating such evidence is essential.[155]/2018
Human bite marksAssault victims were surveyed using an objective structured questionnaire, and the results were analyzed.The common occurrence of biting in assault cases should be considered.[154]/2018
Human bite marksThree bite mark traits (mesiodistal widths, rotation angles of upper and lower right central incisors, and intercanine distances) were measured and compared with the actual sizes using Photoshop.Some factors such as skin properties and posture affect the accuracy of measures and interpretation of bite mark injuries.[149]/2019
Blood group
Extracted dental pulpThe blood grouping and Rhesus (Rh) typing were conducted by slide-agglutination and absorption-elution (AE) technique.Dental pulp tissue was emphasized as a potential source for blood grouping.[165]/2012
Soft and hard dental tissuesThe reliability of longly stored teeth as a source for blood grouping was assessed by a modified absorption-elution method.Hard and soft dental tissues could be efficiently used for personal identification.[166]/2013
Cheiloscopy and blood groupsAny significant association between lip print types and blood groups was searched.Lip prints and blood groups did not show any correlation.[125]/2014
Tooth pulpDNA was extracted from dental pulp tissue of exfoliated primary teeth, and PCR-based blood grouping was done.PCR is proven to be an effective method for blood grouping.[162]/2016
Dentin and pulpThe ABO blood grouping and Rh typing were conducted on dentin and pulp of extracted teeth by the AE technique.The blood grouping showed more sensitivity and significance than the Rh factor typing.[163]/2016
RBCs and salivaSecreting status and blood group were simultaneously identified using antibody array, and ABH antigen was detected by surface plasmon resonance (SPR) imaging.SPR detected almost similar ABH antigen densities both on RBCs and in the saliva.[70]/2017
Cheiloscopy and ABO blood groupsThe association between cheiloscopic patterns/lip print types and blood groups was examined.The findings showed an association between B+/A+/O- blood groups and type IV lip print and O+/AB+ blood groups and type II lip print.[161]/2017
Pulpal tissueThe blood group determination was conducted AE method.The dental pulp is an adequate identifier, especially where teeth are the only practical remnant.[5]/2017
Dry salivary samplesThe results of blood grouping and Rh typing from dry salivary samples were compared with those obtained from the extracted socket.The results were comparable making dried salivary samples a suitable source for personal identification, especially in mass disasters.[164]/2018
