Fracture of tooth after trauma is distressing to a person because of the discomfort and pain due to pulpal injury. Crown root fractures of anterior teeth cause concomitant periodontal injury and there will be concern about appearance, and aesthetics. Management of pulpal and periodontal tissue relieves pain and restoration of tooth form regains patients confidence. Restoration of fractured toot...

Wind turbines generate a low level noise and would thus not be expected to cause annoyance and disturb rest. In a society where people are being exposed to an increasing noise load, moderate and low level noise sources may also be perceived as annoying and hence inhibit restoration. This article presents an analysis of two socio-acoustic studies of wind turbine noise with the emphasis on percep...

Restoration of image sequences is an important problem that can be encountered in many im age processing applications such as visual communications robot guidance and target tracking The independent restoration of each frame in an image sequence is a suboptimal approach be cause the between frame correlations are not explicitly taken into consideration In this paper we address this problem by p...

Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...

In this paper we present the effects of environmental factors and zooplankton food pressure on phytoplankton in the restored man-made Maltański Reservoir (MR). Two methods of restoration: biomanipulation and phosphorus inactivation have been applied in the reservoir. Nine taxonomical groups of phytoplankton represented in total by 183 taxa were stated there. The richest groups in respect of tax...

With the United Nations Decade on Ecosystem Restoration, restoration of damaged ecosystems is turning into a global movement. Restoration actions that are not based science and an understanding ecosystem function can thwart desired outcomes at best cause further damage to worst. often includes revegetation using seed. Where we source seed for make difference species establishment, outcomes, rec...

This book consists of 14 chapters covering important aspects in regards to various terrestrial ecosystems, wetlands, river systems, mine site rehabilitation, marsh ecology and heavy metals pollution. Also aims to fill some of the information gaps in ecological restoration, particularly in under-researched ecosystems around the world. Restoration ecology emerged as a separate field in ecology in...

Skin burns are common skin injuries that can result from exposure to various sources of heat by which, depending on the cause, different degrees of burns are generated. In restoration of superficial burns by re-epithelialization, the skin is rebuilt, but the skin color is different than the healthy tissue. Keratinocytes represent the major cells of the epidermis. These cells are sourced from ec...

Objectives This study aimed to evaluate the retention of composite restorations of primary anterior teeth reinforced with composite posts, glass fber posts, para-pulpal pins with composite posts, and para-pulpal pins alone. Methods Forty freshly extracted sound primary canine teeth with at least two-third of the root length remaining were selected. After disinfection, the tooth crown was cut...
