This paper investigated a 12-slot/11-pole flux switching permanent magnet (FSPM) machine used for electric vehicles (EVs). Five novel rotor teeth shapes are proposed and researched to reduce the cogging torque and torque ripple of the FSPM machine. These rotor teeth shapes are notched teeth, stepped teeth, eccentric teeth, combination of notched and stepped teeth, and combination of notched and...

This study aimed to determine variations in the dental status of a dentate adult population in terms of "decayed," "missing," and "filled" teeth in relation to several sociodemographic and behavioral factors. Quota sampling was used to draw 2531 subjects aged 20 years and over. Data were collected by means of a questionnaire and an oral examination. Multiple logistic regression analyses were pe...

Although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. This paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. This report describes questions concerning...

AIMS This article aimed to characterize the incidence of supernumerary teeth in Turkish children according to sex, location, number and morphology and to explore possible correlations between these variables. METHODS The study population comprised 7,551 non-syndromic patients aged 3-16 years who applied for routine check-ups at the Ankara University Department of Pediatric Dentistry between J...

Harold Vernon first introduced acrylic polymers as denture base materials in 1937. A survey showed that 33% of denture repairs were to restore debonded teeth.1 Factors that affect the bonding of acrylic resin teeth to the denture base are dewaxing procedures, residual wax on ridge laps of teeth,2 and careless application separating media like sodium alginate to the teeth, leading to contaminati...

The aim of this study was to compare the morbidity of permanent teeth associated with mandibular fractures treated with plates with those treated with interdental wiring. Fractures involving third molars were excluded. Sixty-three teeth in the line of fractures in 40 patients were investigated clinically (tooth vitality; periodontal status) and with periapical radiographs. Of these, 34 teeth we...
