Orthodontics and Endodontics: clinical decision-making
ABSTRACT Endodontically treated teeth may be moved, as endodontic treatment is not a contraindication for orthodontic treatment. Apical periodontal repair begins when the periapical or pulp lesion has completely resolved. This may happen immediately after treatment if the filling material causes little or no irritation of periapical tissues, and particularly if the material is fully contained within the canal. When it leaks, a foreign body granuloma forms and persists for some months or indefinitely, depending on the composition of the filling material. Materials containing calcium hydroxide with no resin components underg...

Extensive orthodontically induced dental resorption: What to do?
ABSTRACT If essential care is thorough, teeth with extensive orthodontically induced dental resorption can have the same endurance as normal teeth. These teeth are subjected to the same disturbances as normal ones, such as dental trauma, dental caries and periodontal disease, all of which are independent of severe dental resorption. Orthodontic retreatments of teeth presenting with extensive orthodontically induced dental resorption must take into consideration that these roots are shorter in length, therefore, they are more prone to root resorption. Conventional movements are not viable in severe resorption, but Orthodont...

Transverse maxillary deficiency: treatment alternatives in face of early skeletal maturation
ABSTRACT Transverse deficiencies should be a priority in orthodontic treatment, and should be corrected as soon as diagnosed, to restore the correct transverse relationship between maxilla and mandible and, consequently, normal maxillary growth. Corrections may be performed at the skeletal level, by opening the midpalatal suture, or by dentoalveolar expansion. The choice of a treatment alternative depends on certain factors, such as age, sex, degree of maxillary hypoplasia and maturation of the midpalatal suture. Thus, the present study discusses different treatment approaches to correct maxillary hypoplasia in patients wi...

Concrescence: can the teeth involved be moved or separated?
ABSTRACT The atrophy of the periodontal ligament places the tooth very close to the bone or another tooth, as occurs in unerupted teeth. The absent interdental bone and the lack of functional periodontal stimulus may lead to the fusion of the appositional layers of cement between the roots of the teeth. Concrescence almost always occurs in the region of the maxillary molars. Asymptomatic, it should always be remembered when the proper response to orthodontic movement is not obtained, and there is no apparent explanation. When surgically extracting a tooth and there is resistance, insisting will not be the best strategy. Mo...

ABSTRACT The demand for orthodontic treatment in adults has been increasing. However, these patients often require a multidisciplinary approach, due to the lack of posterior teeth, requiring additional anchorage. The skeletal anchorage by endosseous implants is an option, since they may be used later for prosthetic rehabilitation. The application of immediate load on these appliances for orthodontic movement may reduce the costs and total treatment time.
