Agar-Paraffin double embedding technique is a simple technique that combines the advantages of both the embedding material. It preserves the minute tissue biopsies in orientation and holds them together from getting lost. Oral biopsies, being most commonly small incisional tissues, have to be preserved all through the processing and embedding to ensure optimal visualization of all the mucosal layers without compromise. In the present study, samples were divided into two groups: Group A: Agar-paraffin double embedding (APE) and Group B: conventional paraffin embedding (PE). Tissue samples collected were sectioned into two approximately equal sized bits. Both the bits were simultaneously processed, embedded in two different techniques (APE and PE method). Sections obtained were scored by an observer and analyzed using independent sample t-test (SPSS software version 21) to evaluate the efficacy of agar-paraffin double embedding technique in comparison to the conventional paraffin embedding technique. Agar paraffin embedded tissue was found to be well processed, firm and well preserved. Orientation was comparatively easier and the blocks yielded sections of good quality. They showed no interference with staining and cell morphology was of good clarity. Thus Agar-paraffin embedding technique represents a simple, reliable method that can greatly improve the quality of diagnostic information.Keywords

Background: Forensic odontology plays an important role in identification of man-made or natural disasters event which restricts identification through conventional methods. Various approaches have been specified which helps in the identification of the post-mortem remains. One such is the identification of the morphological features of the human skull and mandible. These features may help in sex differentiation. The aim of this study is to evaluate the relationship between radiographic evaluation with age and gender.
Materials and Method: A retrospective study was done with a total of 250 panoramic radiograph image. The images of 150 males and 100 females were selected with the range of age from 20 to 70 years old and divided into group 1 (20-45 years old) and group 2 (46-70 years old). Three parameters were evaluated from the panoramic radiograph which were gonial angle, antegonial angle and mental foramen against the age and gender. Statistical analysis was done for hypothesis testing.
Results: The results of this study suggests that there is no significant difference seen in the gonial angle and antegonial angle with relation to the age (p≥0.05). However, the relationship between age and mental foramen is highly significant (p≤0.01). With regards to gender, all the three parameter shows highly significant results with (p≤0.01).
Conclusion: In conclusion, the three parameter assessed in this study can be used for gender differentiation but not for age estimation which were highly significant. As for age estimation, the distance of mental foramen and tangent line of inferior border of mandible can be assessed.

Background: The study of lip prints, is commonly applied in forensic odontology and it is known as cheiloscopy. The term cheiloscopy was derived from Greek words, in which “cheilos” means lip and “scopy” means to examine. In general, cheiloscopy is define as a method of identifying an individual based on the arrangement of lines seen on the red part of the lips or a science dealing with the various line appearing on the red part of the lips. The pattern of wrinkles and grooves that are present on the lips has distinct characteristic features of an individual which are almost similar to the fingerprints. It also will not change throughout the life. Therefore, it can be used for personal identification and sex determination.
Aim: To investigate lip print pattern in males and females and to evaluate them between Malaysian and Indian population.
Materials and Method: There were 40 participants of both gender. 20 of them are from the Malaysian population and another 20 people are from the Indian population. Each participant was instructed to clean their lips with a clean white cloth, before taking the lip print. This was followed by the application of dark coloured lip stick on lips by using the lip stick applicator. Cellophane tape was used to take the negative impression of the lip pattern. The glued portion of the cellophane tape was placed on the lips by giving a light pressure beginning from the centre of the lips till the corner of the mouth. Then, the impression was transferred to a clean white paper and seen under the magnifying glass.
Results: Type I lip pattern was commonly seen in Indian population, followed by type III, II and IV. Whereas for Malaysian population, type III was most common followed by type I, II and IV. There was significant difference between both population. In this study, it showed that type I was the most common lip print pattern seen in both Indian and Malaysian population for females. Whereas for male, type III was more common in Malaysian population, and both type III and IV were more common in Indian population.
Conclusion: There was no significant difference in both population according the general distribution of lip print pattern. There was no correlation or similarity of lip print patterns between each participants in both population. Thus, cheiloscopy can be used for sex determination and also personal identification.
