OBJECTIVE To investigate which hard and soft tissue factors relate with the amount of buccal corridor area (BCA) during posed smiling. MATERIALS AND METHODS The samples consisted of 92 adult patients (19 men and 73 women; 56 four first bicuspids extraction and 36 nonextraction treatment cases; mean age = 23.5 years), who were treated only with a fixed appliance and finished with Angle Class I...

AIM To describe the shaping of Small Root canals with GT files. SUMMARY Small Roots are lower incisors, two and three canal bicuspids, buccal roots of upper molars, and mesial roots of lower molars. The Shaping Objective instrument for such cases is usually a 0.08 or 0.06 taper GT file. After proper access, pulp tissue should be removed to prevent its compaction and canal blockage. Orifice sh...

STATEMENT OF THE PROBLEM Similar to conventional amalgam, high-copper amalgam alloy may also undergo corrosion, but it takes longer time for the resulting products to reduce microleakage by sealing the micro-gap at the tooth/amalgam interface. PURPOSE The aim of this study was to evaluate the effect of self-etch adhesives with different pH levels on the interfacial corrosion behavior of high-...

INTRODUCTION The goal of our study was to construct a map of the implant sites in the region of the attached gingiva around the maxillary first molars that would be appropriate locations for placement of miniscrews to serve as orthodontic anchorage. METHOD We conducted 58 radiographic examinations with the NewTom 3G(®) cone beam technique. For each interdental space, between upper second bicu...

T HE superlative for logical dental reasoning during the first half of the present century might be awarded to Dr. John Hunter for his views on the theory of dental foci of infections, and to Dr. Gysi a close second for his studies of the geometric movements of the mandible. However, it is not the intention of this paper to dwell on the work of either of these men, but to discuss in part a prac...

The ameloblastoma is a benign ectodermal tumor of odontogenic origin and is considered to be the most common epithelial odontogenic neoplasm. It represents only 1% of all tumors or cysts of the jaw 1,2 . About 75% of ameloblastomas occur in the mandible, especially in the regions of the bicuspids and molars and in the angle of the mandible. The remaining 25% of ameloblastomas occur in the maxil...

The specialty of orthodontics has continued to evolve since its advent in the early 20th century. Changes in treatment philosophy, mechanics, and appliances have helped shape our understanding of orthodontic tooth movement. In the 1890‘s, Edward H. Angle published his classification of malocclusion based on the occlusal relationships of the first molars. This was a major step toward the develop...

Editorial In the discussions concerning early treatment in orthodontics, a general conclusion during the latest years has been that a suggested time to start the orthodontic treatment is when the second deciduous molars become loose and when the mixed dentition is turning to it's end. This makes sense in the way that when we take into account the occlusion. We have the possibility to move many ...

This study observed the prevalence of different types of residual ridge inclination in free-ends of mandibles and reported possible correlative factors that may affect resorption. For this purpose, periapical radiographs and individual data collected from a sample of 64 hemiarches were used. Two radiographs were taken of each freeend, and tracing was employed to determine the angles formed by t...

Serial Extraction or the guidance of eruption is an age old procedure to correct crowded arches and is still used in routine dental practice. But the efficacy of this procedure has always been controversial and it requires very precise clinical skill for a favorable outcome. This article presents a review regarding the proper selection of cases for serial extraction, its limitations and various...
