Cheiloscopy: An evolving tool in forensic identification Ganapathy Nalliapan, Maheshwari Ulaganathan, Yamunadevi Andamuthu, Maheswaran Thangadurai, Ilayaraja Vadivel, Tamil Thangam Periyasamy Journal of Indian Academy of Dental Specialist Researchers 2018 5(2):37-41 Cheiloscopy deals with the identification of humans based on lip traces. “Cheilos” is a Greek word meaning lip and “Scopy” means to examine. Human identification is one of the most challenging subjects. The lip print of every person is unique. The grooves present on the lips (sulci labiorum) are unique for every person and can be used in individual identification. In forensic identification, lip print pattern gives us important information and helps in individual identification. Lip prints are normal lines and fissures in the forms of wrinkles and grooves present in the zone of transition of human lip of inner oral labial mucosa and outer skin or vermilion border. The study of these grooves or furrows is known as cheiloscopy.

Application of lasers in prosthodontics: A review N Devi, P Arun Kumar, M Rakshna, KR Rameshkumar Journal of Indian Academy of Dental Specialist Researchers 2018 5(2):42-45 LASERS has a wide range of action, and it is application in the field of prosthodontics have replaced scalpel to reasonable extend all over the surgical field and other conventional methods. An upcoming new technology replaces several shortcomings but by having its own risks and limitations. The aim of this article is to elaborate the application and uses of lasers in prosthodontics and the revolution by lasers in providing precise procedures to the patient.

Evaluation of changes in the surface topography of implant after implantation N Devi, KR Rameshkumar, P Arun Kumar, R Ajay, K Divya Journal of Indian Academy of Dental Specialist Researchers 2018 5(2):46-51 Objective: This study aimed to evaluate the changes in the surface topography of implant system after implantation procedure. Materials and Methods: Branemark implant system was selected and placed and removed in the patient and viewed under SEM for the changes in surface topography. Sandblasting, plasma spraying, and acid etching are the most common approaches used by manufacturers to alter surface topography and increase the surface area of implants. Changes on the implant surface are known to affect the percentage of osseointegration and success of the procedure. The various surface modifications, which aid in osseointegration, could be affected by the insertion torque (35–45 N) exerted during implantation. In this study, we have used SEM – Stereo Scan 440 to evaluate the surface topography. Results: The SEM images of the implant system after implantation showedat there is no noticeable difference between the apical and middle portions of the implant. Surface irregularities (roughness) reduced in the coronal portionof the implant. Conclusion: Implant surface topography is not the only criterion for implant success; the other considerations such as type of bone, quality of bone, and host response also have an important role in implant success. The complete characterization of complex surface topographies of commercial implants requires more than one method to describe the whole surface topography, from macro to nano range.

Nonsyndromic oligodontia in siblings V Vinothini, A Sanguida, KR Prem Lal, GS Prathima Journal of Indian Academy of Dental Specialist Researchers 2018 5(2):52-54 Tooth agenesis is a condition where the teeth are missing due to developmental failure. Congenital tooth agenesis can be either hypodontia or oligodontia. Oligodontia can occur either as an isolated condition or it can be associated with other genetic syndromes. The exact etiology of oligodontia is unknown. A multidisciplinary staged approach of the management is required that includes endodontic, restorative, surgical, and orthodontic procedures to improve the esthetics and function. The present article reports a rare case of oligodontia in siblings identified and treated in the mixed dentition with 1-year clinical follow-up.
