Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin and are managed either by surgical enucleation or by marsupialization. We illustrate the possibility of complete healing of cystic periapical lesions in permanent and mixed dentition with conservation of vital structures. This article aims to report two clinical cases of radicular cysts of huge proportion trea...

This article describes the treatment of a girl in whom anterior trauma during the deciduous dentition had caused a dilacerated maxillary central incisor in the mixed dentition. The dilacerated central incisor was extracted, and a canine was transposed to the extraction site. Canine transposition was performed so that the lateral incisor could be maintained in its normal position. This article d...

INTRODUCTION The purpose of this longitudinal randomized investigation was to determine the long-term changes in the soft-tissue profile during orthodontic treatment when treatment is started with headgear (HG) in the early mixed dentition. METHODS The subjects were 68 children (28 girls, 40 boys; mean age, 7.6 years; SD, 0.3 years) with a Class II tendency in occlusion and moderate crowding....

OBJECTIVE The primary aim of the study was to generate new prediction equations for the estimation of maxillary and mandibular canine and premolar widths based on mandibular incisors and first permanent molar widths. METHODS A total of 2,340 calculations (768 based on the sum of mandibular incisor and first permanent molar widths, and 1,572 based on the maxillary and mandibular canine and pre...

BACKGROUND The aim of the present work was to evaluate the stress magnitudes and directions along the midpalatal suture in the maxillary protraction therapy. METHODS The geometry of the maxilla and teeth were digitally reconstructed based on computer tomography images obtained from the skull of a girl in a mixed dentition stage with skeletal and dental class III malocclusion. An appliance com...

OBJECTIVE To evaluate the relationship between the stages of dental formation and the timing of eruption of mandibular second premolars. MATERIALS AND METHODS The sample comprised panoramic radiographs of 25 children, 7 to 12 years old, observed by space supervision during development of dentition. The initial radiograph (T1) was taken in the mixed dentition period and the progress radiograph...

Midline diastema is a space between the central incisors. Although physiologic transitory maxillary midline diastema is observed in children during eruption of maxillary anterior teeth in most cases, it is self-corrected after eruption of maxillary canines. However, midline diastema unrelated to the eruption of teeth has been observed owing to various etiologic factors. Treatment to align the c...

The aim of this study was to examine the differences in the early craniofacial morphology of Class Ill malocclusions. Lateral cephalograms of 45 subjects with a Class III malocclusion and an anterior crossbite in the deciduous or mixed dentition were examined before treatment, after treatment, and during the long-term retention stage. The anterior crossbites of all patients were corrected after...

BACKGROUND/AIM Malocclusion of skeletal class III is a complex irregularity of sagittal inter-jaw relationship, which is due to irregularities of sagittal position of one or both of the jaw bones, which is often associated with disproportionate ratio of their length. The aim of this study was to determine whether the length of the jaw of children with skeletal class III in the period of mixed d...
