AIM The aim of this study was to evaluate the long-term effects of Class 2 functional treatment on airway dimensions and positional changes in hyoid bone and compare it with that of an untreated Class 2 control group. METHODS Lateral cephalograms of 16 patients (eight girls, eight boys, mean chronological age = 11.36 ± 0.77 years) who were treated with(More)
The objective of this study was to investigate the effects of fixed functional therapy on oropharyngeal airway dimensions and hyoid bone positions in Class II patients and make comparison with an untreated Class II group. Eighteen patients (8 girls, 10 boys; mean age 13.62 ± 1.92 years) who were treated with Forsus Fatique Resistant Device (FFRD) and 19(More)
The present study was conducted to evaluate the effects of some types of herbal tea on the shear bond strength (SBS) of orthodontic brackets to enamel surfaces. The brackets were bonded with Transbond XT to 90 extracted human premolar teeth and divided equally into six groups, that is, black, mint-mate herbal, mint-lemon herbal, and rosehip fruit tea and(More)
INTRODUCTION The aim of this study was to analyze the effect of an enamel-protective resin on the shear bond strength (SBS) of orthodontic brackets bonded with self-etching primer. METHODS Eighty extracted premolars were randomly divided into 4 groups of 20, and metal brackets were bonded. Group 1 specimens were bonded with Transbond Plus self-etching(More)
INTRODUCTION Our objective was to evaluate the effects of a highly filled light-cured sealant (HFLCS) on the shear bond strength and bond failure site of metal and ceramic brackets bonded with resin-modified glass ionomer cement (RMGIC). METHODS Eighty freshly extracted maxillary premolars were randomly divided into 4 groups (20 in each group). In all(More)
INTRODUCTION The aim of this study was to evaluate the effects of the Class II activator and the Class II activator high-pull headgear (HG) combination on the mandible with 3-dimensional (3D) finite element stress analysis. METHODS A 3D finite element model of the mandible was constructed from a dry human mandible. To investigate the effects of the Class(More)
The objective of the present investigation was to determine the intrapulpal temperature changes and to compare the shear bond strength (SBS) of bondable buccal tubes bonded by high-intensity light sources. Ninety caries-free human first molar teeth extracted for periodontal reasons were used. For the temperature measurement test, 30 teeth were randomly(More)
SUMMARY The purpose of this study was to evaluate changes in dentofacial growth before, during, and after use of a magnetic activator device (MAD) II in high-angle Class II division 1 patients. Lateral cephalometric and hand-wrist radiographs of 10 patients (six girls and four boys) with an average chronological age of 10 years 5 months were obtained at the(More)
In this paper, surface roughness models for a substrate integrated waveguide (SIW) are proposed. Frequency-dependent conductivity is introduced to model the conductor loss due to surface roughness. To be specific, two models, namely, the modified Huray model and the rigorous waveguide model, are developed. Both models take into account the mode-dependent(More)
