The science of Implantology has undergone numerous modifications and improvement and is highly dynamic. With each improvement and advancement, Implantology has proved to be a boon in disguise to the society and hence its acceptance by the general population has widely increased despite of expensive treatment modality. More of clinical trials conducted on different commercially available implants, its effect on bone and oral tissues as well as the development of implant designs, have increased the success rate of implants to over 95% and specially in anterior mandible where the success rate is over 99%. Latest technological advances in Dental Implantology are reviewed in this article.
The standard reasons for market failure in the health sectorasymmetric information, moral hazard, externalities and public goods nature of a large number of health goods and services interventionsare central in the context of infectious diseases and make it imperative for governments to intervene to improve uptake of prevention services. Behavioral economics (BE) offers a framework to understand individual choices and preferences in the face of risk and uncertainty that might seem less than optimal from a public health perspective and make standard strategies ineffective to deal with the spread of infectious diseases. Globally, countries have attempted to incorporate innovative strategies that elicit behavior changes in their public health programs, and evidence exists to indicate what might have worked and how. This chapter reviews recent lessons from such experiences with prevention strategies that particularly focus on the behavioral dimensions of prevention for four diseases-HIV/AIDS, tuberculosis (TB), malaria, and diarrheal diseases, to
Primary fallopian tube cancer is a rare entity in patients who present with bilateral hydrosalpinx. We present a case of bilateral hydrosalpinx with pain. We did laparoscopic salpingectomy with frozen section which revealed malignancy. This was followed by staging laparotomy. Strong index of suspicion is required in patients with hydrosalpinx for the efficient management of the patient.
Objective: To compare and evaluate the fracture resistance of endodontically treated molars reinforced with various bonded restorations and to study the type of fractures in various restorations. Methods: Forty extracted mandibular molars were endodontically treated. MOD (Mesio-Occluso-Distal) cavities were prepared and Mesio-Buccal cusp was reduced in all to provide cuspal coverage. All the teeth were then divided into 4 groups. The cavities in group 1(control) were filled with high copper amalgam. Group 2 was restored with direct resin composite. In group 3 after the priming and bonding procedures as in group 2, cavity surfaces were coated with flowable resin composite. Before curing a piece of polyethylene ribbon fiber was cut and coated with adhesive resin and was embedded inside the flowable composite. The resin composite was cured with visible light cure (VLC) gun. For group 4, restorations were done according to the recommendations provided by the manufacturers of SR Adoro (Ivoclar-Vivadent, Schaan, Liechtenstein) composite material. Compressive fracture strength test was performed after at least 24 hours of the fabrication of the specimens, by application of compressive loading in a Universal testing machine, applied on the occlusal aspect of each specimen with a steel bar. The mean loads necessary to fracture were recorded in Newton and the results were statistically analyzed. Results: Group 4 (indirect composite inlay) had the greater fracture resistance and group 1(Amalgam) had the poorest. Difference between group 1 and 3, group 1 and 4, group 2 and 4 were statistically significant. No statistically significant difference was found between group 1 and 2, group 2 and 3, group 3 and 4. Predominant type of fracture in group 1 and 3 was fracture of tooth below cemento enamel junction at tooth restoration interface without mesio buccal cusp involvement. In group 2 and 4, predominant fractures were of tooth below cemento enamel junction through center of restoration without mesio–buccal cusp involvement.
Achieving and maintaining implant stability are prerequisites for a dental implant to be successful. Implant stability can be defined as the absence of clinical mobility, which is also the suggested definition of osseointegration. Primary implant stability at placement is a mechanical phenomenon that is related to the local bone quality and quantity, the type of implant, and placement technique used. Secondary implant stability is the increase in instability attributable to bone formation and remodeling at the implant–tissue interface and in the surrounding bone. There are many ways in which the implant stability can be evaluated such as clinical measurement of cutting resistance during implant placement, reverse torque test, and the periotest. This article aims to throw light on the various methods to determine implant stability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
