Fracture of anterior teeth due to trauma is the most frequent type of injury affecting permanent dentition. Despite the availability of a wide range of restorative materials, none could match the properties of natural tooth structure like translucency, wear resistance, and color stability. Hence fragment re-attachment is an excellent method of restoring fractured teeth. When the fractured fragm...

A study was conducted to determine the degree of tooth loss, factors influencing tooth loss, and the extent of prosthodontic rehabilitation in Sudanese adults (≥ 16 years old) attending outpatient clinics in Khartoum State. Pearson and multivariate analyses were used to examine the relationships between tooth loss and specific characteristics determined through interviews and clinical examinati...

INTRODUCTION The purpose of this study was to investigate the variations of orthodontically induced tooth movement in the maxillary and mandibular arches between patients and the factors such as age, sex, and presence of an interference that might influence the amount of tooth displacement. METHODS By using a standardized experimental orthodontic tooth movement in 30 subjects, 57 premolars we...

BACKGROUND Tooth filling treatment is utilized at low levels in many low and middle-income countries (LMICs), further, little is known about the prevailing attitudes towards such treatment. This study aimed to assess attitudes towards tooth filling among Tanzanian adults and how previous tooth filling experience is associated with these attitudes. METHODS A pretested structured questionnaire ...

Although preventive measures have reduced caries, premature loss of pulpally involved primary teeth remains a common problem. The resultant mesial drift of the permanent teeth frequently leads to malocclusion. Retention of the pulpally involved primary tooth to preserve arch space is preferable to space maintenance if the tooth can be restored to normal function and is free of pathology. Additi...

Migration is the permanent movement of some people called migrant, from one place to another for some reasons and values. Their migration is determined by some values and goals that lead to changes in migrants’ interaction system. In human history the shape of migration was changed due to social and environmental changes. From the eve of 19 century migration became important social phenom...

This paper introduces novel a two-phase permanent magnet BLDC (PMBLDC) motor with both an asymmetric tooth and an auxiliary tooth in order to improve the dead point, efficiency and torque ripple. To calculate the merits of introducing each of the asymmetric tooth and the auxiliary tooth, characteristic analysis is performed respectively using finite element method (FEM). To maximize performance...

principal management option in the treatment of pancreaticobiliary disease. Longterm complications include occlusion, migration, and dislocation [1–3]. Duodenal perforations caused during stent migration are rare but life-threatening [4], with complications including peritonitis, sepsis, retroperitoneal abscess, and duodenal fistulization [4–5]. This report describes an asymptomatic case of duo...
