PURPOSE The aim of this study was to assess dental anchorage qualities when the pendulum appliance is used for distal molar movement. MATERIAL Thirty adolescents in various dentition stages received a modified pendulum appliance with a distal screw and a specially preactivated pendulum spring for bilateral molar distalization in the maxilla. The subjects were subcategorized into 3 groups of 1...

This report describes a case of a 14-year-old girl showing a late eruption of the central and upper right central incisor. The intrusion of superior front incisors occurred when the patient was ten months old. Radiographic examination revealed the presence of an odontoma-like malformation on element 12. The objective of this report is to describe the diagnostic procedures, the etiology, the cli...

Early treatment of certain malocclusions is of great importance in orthodontics when normal growth and development is the objective of our therapy. The four cases presented illustrate the three types of malocclusion which must be treated early: cross-bites (transverse), Class III malocclusions (saggital) and open-bites (vertical). In most of these cases there is a deficiency of the maxilla. The...

A limited number of investigations have appeared in the literature which have attempted to estimate the age of rhesus monkeys on the basis of dental development. These studies have shown that tooth emergence can be used as a guide for age estimation of normal, healthy rhesus monkeys. Twenty-one infant rhesus monkeys (Macaca mulatta) were used in this study. The animals were fed a high protein l...

Parents' understanding of the dental therapy to retain deciduous tooth space may influence treatment plans. Parents should be made aware consequences such matters through comprehensive educational initiatives, as well preventive measures that can taken for children during primary or early mixed dentition, importance maintainers in preventing loss and a variety malocclusions. To minimize exp...

A thorough knowledge of root canal anatomy and its variation is necessary for successful completion of root canal procedures. Morphological variations such as additional root canals in human deciduous dentition are rare. A mandibular second primary molar with more than four canals is an interesting example of anatomic variations, especially when three of these canals are located in the distal r...
