 Forensic science is vast and dentists are privileged to play a prominent part of the investigating team, since the oral cavity area is small but highly resistant to destruction. Dentists should accept the challenge to play the part in investigation when called on by studying, doing research and keeping equipment ready. Forensic dentistry generally addresses the problem of identifying individuals based on the properties of teeth. Looking at the location, orientation, presence/absence, and dental work, people can be matched to dental records or bitemark impressions for identification. The present review describes the classification, characteristics, mechanism of production, and appearance of bite mark injuries, collection of evidence, comparison techniques, and technical aids in the analysis of the bite marks.

 Periodontics can be considered as a clinical dental specialty with significant potential for applications in forensic odontology. This specialty can be utilized for identification of individuals through morphology and pathology of periodontium and also for age estimation studies based on root transparency and root length. The aim of this review is to briefly discuss a periodontal perspective in aiding forensic investigations.

  Oral hygiene plays an important role in children’s overall health, functional capacity and social welfare. Special children may have compromised oral health because of low socio-economic status, other health conditions, lack of trained providers, lack of awareness and knowledge amongst care givers. Hence, the management of these, God’s forgotten children is a task which needs special effort on the part of the dental surgeon. The dentist who plan the treatment of the special children should be skilled, should have knowledge about the condition from which the child is suffering and should be clinically equipped to handle any emergency if occurs during any dental procedure. the following review is an attempt to provide an insight into the condition of ADHD and its associated aspects along with the management of such children.

  Objective: The aim of present study was to assess the age and sex related changes in Haller cells height and width.This study also help in prediction of age of an individual if Haller cell height/ width is known. Material and Methods: The study population consists of 152 study subjects with age range from 7 to 74 years. The CBCT images of 152 study subjects were analysed prospectively. All the CBCT images are obtained at 90 Kvp,4 mA for 11.3 seconds at FOV(17"x13.5") voxel size of 300. The height and width of haller cell is measured by using Trophy Dicom Ink software programme on coronal images (DICOM images). Results: There was no statistically significant (P>0.05) co-relation between Haller cells height and width (right side) and age groups noted. The mean Haller cell height in right side was statistically significant (P<.05) in male and female. It was higher in females than males. Haller cell width in left side is directly associated with age of females and demonstrated a significant positive relation. Conclusion: The morphometric evaluation of haller cells can be used for age and sex determination in medico-legal cases, evidence lacking incidents etc.

 Aim: To find the relationship between dermatoglyphics pattern and dental caries in punjab population. Materials and Methods: This study was conducted on the total of 100 subjects, 50 females, 50males in age group between 15- 20 years and persons with dental caries in 3 or more teeth based on DMFT index were included in the study. The fingerprints were recorded and statistical analysis was performed. Results: 1. Fingerprints of male showed more no of loop patterns. 2. Based upon caries index male population was found to have more caries as compared to females. 3. A significant increase in dental caries was associated with loop pattern. Conclusion: Dermatoglyphics can prove to be an extremely useful tool for preliminary investigations.

 Objective: This study aims at age and sex related changes in length, width, depth and antero-posterior diameter of Sella turcica. The age and sex is also determined on the basis of length ,width, depth and anteroposterior diameter of sella turcica. Material and Methods: The CBCT images of 200 study subjects were analyzed prospectively. All the CBCT images are obtained at 90 Kvp, 4 mA for 11.3 seconds at FOV(17"x13.5") voxel size of 300. The length, width, depth and antero-posterior diameter of Sella turcica is measured by using Trophy Dicom Ink software programme on sagittal images (DICOM images). Results: The study population consists of 200 study subjects aged between 18 years to 70 years with a mean age of 30.49±14.626 years. The unpaired t-test shows no significant difference in length, anteroposterior diameter, width and depth of Sella turcica and gender of study subjects. One way ANOVA shows there is significant difference (P<.001) observed in length, width and depth in age groups while anteroposterior diameter has no significant difference in age groups. The study parameters are co-related with age by using Pearson correlation coefficient(r) and it shows that there was significant positive correlation between age of study subjects with length, width and depth of Sella turcica. However there was no significant correlation between age of study subjects with antero-posteriordiameter.  Conclusion: The Sella turcica can be used as morphometric tool in age and sex determination of a deceased person, medicolegal cases and forensic sciences.

 Aim/Background: Cheiloscopy is the study of lip prints. Lip prints are unique for individuals. Lip prints can be visible or latent. Lip prints not leaving a visible smear are considered as latent lip prints. These can be present on different porous and nonporous surfaces. Various dyes have been used for the development of latent lip prints on different surfaces. This paper compares the efficacy of naturally available Vermilion powder with that of a lysochrome dye, Sudan III for the development of latent lip prints on different porous and nonporous surfaces. Materials and Methods: Two sets of latent lip prints were made on eight different porous and nonporous surfaces. These latent prints were developed by applying Vermilion powder and Sudan III and evaluated for clarity of lip grooves. Results: Latent lip prints were developed on majority of surfaces. Lip prints developed with Vermilion powder were comparable to those developed with Sudan III on porous surfaces, while they were better visualised on nonporous surfaces. The lip prints could be appreciated more clearly on nonporous surfaces compared to the porous ones.
