cents has always relied on growth modification. The majority of treatment modalities, such as functional appliances, are directed at stopping or redirecting maxillary growth and simultaneously stimulating mandibular growth.1-3 On the other hand, in adult patients with severe Class II malocclusions, generally involving extremely deficient mandibles, orthognathic surgery is often the only possibl...

THE airway management of a surgical patient is one of the anesthesiologist’s primary concerns. The combination of several parameters seems to predict difficult laryngoscopy and intubation: short thyro-mental distance, protruding incisors, micrognathia, small mouth opening, acromegalic features, short neck, morbid obesity, and others. This case report describes another rare and frequently unreco...

The frequencies and chronology, based on a standard tooth development chart, of enamel hypoplasia derived from permanent upper central incisors and mandibular canines were compared for 42 prehistoric Amerindians. Between 0.5 and 4.5 years, when the crowns of both these teeth are developing, hypoplasias were 1.36 times more common on the incisors (54 hypoplasias/incisor; 40 hypoplasias/canine). ...

To investigate whether the relationship between tooth shape ratio and incisor arrangement proposed by Peck et al. in 1972 was applicable to Japanese children, we compared two groups, one with normal permanent dentition and another with crowded permanent dentition, using chronologically constructed plaster dentition models. Tooth shape ratio was obtained by dividing the incisor mesio-distal widt...

The aim of this report is to describe the treatment of two mandibular incisors of the same patient with apical periodontitis following dental trauma. Tooth 31 was treated by single-visit endodontic therapy while tooth 41 was treated by multiple-visit endodontic therapy. A 16-month postoperative radiograph was taken and showed repair.

The aim of this study was to reveal the morphometric characteristics teeth chinchilla (Chinchilla lanigera), which are both kept as pet animals and raised for economic value their fur, using three-dimensional (3D) reconstructions created from two-dimensional (2D) multidetector computed tomography (MDCT) images investigate whether there a difference between sexes. A total 12 chinchillas sexes (s...

OBJECTIVE The aim of this study was to investigate the three-dimensional (3D) position of the center of resistance of 4 mandibular anterior teeth, 6 mandibular anterior teeth, and the complete mandibular dentition by using 3D finite-element analysis. METHODS Finite-element models included the complete mandibular dentition, periodontal ligament, and alveolar bone. The crowns of teeth in each g...

This report describes the treatment of a 15-year-old female patient with Angle Class I malocclusion, severe maxillary anterior crowding, maxillary midline shift to the left, and maxillary atresia associated with posterior crossbite. The treatment consisted of palatal expansion using a modified Haas expander and placement of a standard Edgewise fixed appliance. Interproximal reduction was perfor...

Orthodontic management for patients with single or bilateral congenitally missing permanent lateral incisors is a challenge to effective treatment planning. Over the last several decades, dentistry has focused on several treatment modalities for replacement of missing teeth. The two major alternative treatment options are orthodontic space closure or space opening for prosthetic replacements. F...
