Introduction: Presence of gap at the implant-abutment interface, leads to microleakage and accumulation of bacteria which can affect the success of dental implants. Aim:To evaluate the sealing capability of different implant connections against microleakage. Materials and Methods:In January 2017 an electronic search of literature was performed, in Medline, EBSCO host and Pubmed data base. The search was focused on ability of different implant connections in preventing microleakage. The related titles and abstracts available in English were screened, and the articles that fulfilled the inclusion criteria were selected for full text reading. Results:In this systematic review, literature search initially resulted in 78 articles among which 30 articles only fulfilled the criteria for inclusion and were finally included in the review. Almost all the studies showed that there was some amount of microleakage at abutment implant interface. Microleakage was very less in Morse taper implants in comparison to other implant connections. Majority of studies showed less microleakage in static loading conditions and microleakage increases in dynamic loading conditions. Conclusion:External hexagon implants failed completely to prevent microleakage in both static and dynamic loading conditions of implants. Morse taper implants were very promising in case of static loading and also showed less microleakage in dynamic loading conditions. Torque recommended by manufacturer should be followed strictly and zirconia abutments were more prone to microleakage than titanium abutments and should be avoided.www.jcdr.net Sunil Kumar Mishra et al

Introduction: The widespread use of cell phone in recent years has raised many questions whether their use is safe to operator who is exposed to Electromagnetic Waves (EMV). Aim:To find out the effect of cell phone emitted radiations on the orofacial structures. Materials and Methods:To identify suitable literature, an electronic search was performed using Medline, Pubmed and EBSCO host database in December 2016. The search was focused on effect of cell phone on orofacial structures. Among the literature available in English, the screening of the related titles and abstracts was done, and only those articles were selected for full text reading that fulfilled the inclusion criteria. Results:The initial literature search resulted in 360 articles out of which only 24 articles fulfilled the inclusion criteria and were included in this systematic review.
