Aim: The aim of this study is to ascertain whether lip prints behold the potential for sex identification. Materials and methods: Study sample included 40 males and 40 females whose lip prints were recorded with help of lip stick. Lip prints were classified into 4 types based on Tsuchihashi classification for sex identification. If type I and II patterns was present, they were classified as females. If type III and IV patterns were present, they were classified as males. Results: Out of 40 males, 34 were correctly identified as males and out of 40 females, 33 were correctly identified as females. Conclusion: If the sex of the person who committed the crime is known, it is easy to shortlist the suspects. Although determining sex with lip prints is not an accurate method, it can be useful as a supplementary method.

Rai B reported that positive correlation between coronal displacement of cementum in impacted teeth and age and proposed BR regression equation for Indian population . Materials and methods -This study was conducted on 100 impacted mandibular third molars extracted from napalase healthy patients , aged between 18 and 22 years. The buccolingual ground sections were prepared and the distance between the edges of enamel and cementum were measured with micrometer attached to a light microscope. Results and conclusion-The following regression equation was derived: Age= (Cementum-enamel distance) +543/29.7. A significant correlation (r = 0.89) between age and coronal displacement of cementum in impacted teeth was calculated and a regression equation was derived for age estimation.

It has been evident that software can enhance the digital photographs. No, particular guideline or directions were published to enhance the ALI, UV and infrared image by Adobe CS3. Adobe CS3 was a software program utilized in this study for enhancement of ALI, UV and infrared images of bite marks, overwriting and five fluids by two methods. There were significantly enhancement of bite- marks, overwriting and fluids images and standard ways were proposed to enhancement of different light images. On comparison, digital enhanced photographs by method II were found good as compared to method 1. This software proved to be valuable tool for bite marks, overwriting, distinguished fluid examination and likely a good resource for enhancing different lights images.

Key words: Adobe phtoshop CS3, Different light photography, Images enhancement.
