objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...
Introdouction:The study aimed to compare the accuracy of proximal caries detection by dental practitioners using two different systems, direct digital system and conventional films, under routine environmental conditions. Materials and methods: Eleven extracted human posterior teeth were mounted on wax frames and were exposed using the direct digital system and conventional films. Seventy-four ...
Introduction: To achieve an ideal health system, a convenient and comprehensive access to information is essential in different steps of decision-making. An Integrated digital library (IDL) is developed by joing individual and scattered digital libraries forming a network and providing services under the control of a centralized manager. The main purpose of this study was to identify and rank e...
Background and Aims: Accurate diagnosis of vertical root fracture (VRF) is a fundamental importance in endodontics. Because of poor prognosis of VRF, digital radiographs with two horizontal angles have limitations in VRF detection. Also, Gutta-percha can produce artifacts that impair CBCT scan accuracy. The aim of this study was to compare accuracy of CBCT and digital radiography system in vert...
Background and Objective: Regulating body temperature of premature infants and preparing them a desirable physical condition for completing physical and mental development is essential. Using a system that guarantees neonate’s health in incubator at first birth hours is cardinal. Materials and Methods: In this method, a set of non-contact infrared sensors and microcontrollers regulate neo...
Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...
Background and Aims: Estimating the canal length is essential for reaching to a proper endodontic treatment. Any error and miscalculation in estimation of the working length, especially in curved canals, can result in complication during and after root canal therapy. The introduction of digital radiography has enabled us to measure curved canal length. The purpose of this study was to evaluat...
variable rate application (vra) based on site specific crop management (sscm) is an effective approach for optimizing the application of agricultural inputs and preventing the undesirable environmental impacts. design, construction and evaluation of a map-based vra system was the main objective followed in this research. for variable rate application based on the generated map, a direct injecti...
