Abstract

Forensic Dentistry is defined as a budding branch of dentistry dealing with dental evidence for human identification. Periodontal tissues are the supporting apparatus of the tooth which has many hidden genetic components that could be useful in the field of Forensic science. This article highlights the importance of periodontal tissues in various aspects of forensic research. Keywords: Forensic research, Periodontal tissues.

Abstract

Smart phones are electronic gadget that is used for many purposes other than communication. Past few years data reveals increased smart phone buyers due to introduction of 4G network. The e-rays emitted from cell phone usually between 301MHz and 950 MHz depending upon the type of device, frequency and duration of use. Long duration of mobile use can lead to increase in temperature of the exposed areas and surrounding tissues. Mobile phone radiation increases production of singlet oxygen through NADPH oxidase, leading to oxidative stress that forms a major etiological factor for various diseases. Increased exposure to smart phone radiation could have ill effects on human body. Particularly, oral cavity & Perioral tissues are frequently exposed to mobile radiation compared to other parts of the body. This review highlights the possible mechanism between effects of cell phone radiations on oral tissues. Keywords: DNA, Surrounding tissues, E-Rays.

Abstract

Extraction followed by placement of immediate implant has become a reliable and time saving method of esthetic and functional rehabilitation of a patient. Achieving good primary stability with preservation of hard and soft tissue is the key to successful placement of immediate implant. With the advent of immediate single-stage implant placement and immediate prosthesis fabrication, the edentulous patients can walk out of the clinic with “Teeth within a day”. Refining clinical protocols, applying sound biomechanical principles, improving implant design, with new implant surfaces have resulted in the increased use of immediate implant. However there are chances of implant failure due to greater crestal bone loss around the healing implants resulting from traumatic extraction. This could be minimized or prevented by atruamatic extraction procedure. Many clinical trials reported survival rates of immediately loaded implants similar to that of two-stage unloaded healing approaches. This article throws a light on atruamatic extraction & various techniques of atruamatic extraction, advantages, disadvantages and success criteria for immediate implant loading. Three cases with different techniques of atruamatic extraction of tooth and immediate implant rehabilitation is reported. Keywords: Atruamatic extraction, Techniques, Immediate implant loading, Advantages and disadvantages of immediate implant loading.
