abstract mothers rely on nurses for help and advice on how to feed their babies. without help, any mothers see breastfeeding as a goal they cannot reach for themselves. so, the nurse plays a significant role in helping the mother to begin breastfeeding and to take pleasure in it; at one fell swoop, the mother provides her infant with optimum nutrition. however, nursing could be hamper...
Analysis of incremental banding in dental cementum is a well-established means of determining the age and season of death of wild mammals. The dental cementum of domesticated mammals likewise can indicate age and season of death. Methods of preparation applicable to archaeological teeth differ from those used for modern specimens, however, and this paper describes two methods that have given ex...
The purpose of this study was to assess the longitudinal relationships between enamel hypoplasia and caries experience of primary second molars. The study sample was 491 subjects who received dental examinations at both age 5 and 9 by the calibrated examiners. Four primary second molars (n = 1,892) were scored for the presence of enamel hypoplasia for each participant. Caries presence and numbe...
One of the major factors in a successful root canal therapy is the determination of root length before canal preparation. Radiography has been proved to be useful in this case, but nowadays for reducing radiation, radiovisiography has been recommended. The aim of this study was comparing conventional radiography (CR) with radiovisiography (RVG) in determination of canal length. 101 anterior and...
The estimation of age of human foetal remains is of great medico-legal importance. When the remains are intact and fresh, various morphological features such as crown-heel length, weight, appearance of ossification centres particularly around the ankles and knees and other parameters could be used to make a reasonable estimation of the period of gestation. In cases of criminal abortion, infanti...
Statement of Problem: Bone material density (BMD) is significantly decreased among postmenopausal women leading to the most common metabolic disease, osteoporosis.Multiple bone fractures are of the most important consequences of this disease, which cost too much for thesociety. One of the cheapest and most available methods for the diagnosis of bone density changes is bone radiomorphometric eva...
AIM To present a tactile method for working length determination in teeth with open apices and to determine its accuracy and repeatability. METHODOLOGY Ninety teeth with 129 root canals were prepared to create open apices. The correct working length (CWL) for each canal was determined by introducing a file into the root canal until it was visible at the apex. Consequently, the tactile working...
Aim: To determine the intensity of the impacted third molar and its clinical correlation. Objective: This study was done to check the impacted third molar and to study its clinical correlation. Background: A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition.Wisdom teeth generally erupt between the ages of 17 and 25.Wisdom teeth commonly affect other teet...
