Space-regaining treatment for a submerged primary molar: a case report.

The aetiology of submerged primary molars is not known and optimal treatment has still not been established. If submerged primary teeth are left untreated, the occlusal consequences are space-loss due to tipping of adjacent teeth and/or overeruption of the opposing teeth. Normally, treatment consists of extraction of the deciduous teeth or observation for normal exfoliation. Here we report a case where the submerged primary molar was extracted surgically after space-loss had been regained.

Reducing the incidence of palatally impacted maxillary canines by extraction of deciduous canines: a useful preventive/interceptive orthodontic procedure. Case reports.

The early detection of palatally impacted permanent maxillary canines is stressed. Appropriate radiographs to determine impactions are suggested and removal of deciduous canines to eliminate impactions in patients who have good dental arches with no space deficiency is recommended. Two case histories are presented to illustrate the method.

Inflammatory follicular cyst associated with an endodontically treated primary molar: a case report.

This is a case study of an inflammatory follicular cyst associated with an endodontically treated deciduous molar with radiographic and microscopic diagnosis. This cystic lesion represents a typical follicular cyst that arose in association with periapical inflammation from a non-vital deciduous molar and involved the follicle of the unerupted successor premolar. This paper describes the case and discusses diagnosis, histogenesis, and controversies regarding terminology.

Dentigerous cyst associated with an upper permanent central incisor: case report and literature review.

Traumas to deciduous teeth may have severe consequences. This article addresses a dentigerous cyst case report associated with an upper permanent incisor, unusual site of occurrence, which was impacted and dislodged from its natural site of eruption after trauma at the deciduous predecessor. The main aspects of etiopathology and its clinical characteristics are also discussed, with special focus on the radiographic features of the diagnosis in order to allow for an accurate surgical planning.

Identification and localization of a mucopolysaccharidase in human deciduous teeth.

The presence of a mucopolysaccharidase in resorbing deciduous teeth was investigated using histochemical techniques. The loss of toluidine blue metachromasia within glycosaminoglycan film substrates indicated the presence of enzyme activity, and was related to physiologic resorption. Such activity was localized to the periodontal ligament of these teeth.

Compound composite odontome associated with an unerupted deciduous incisor--a rarity.

Odontomes are considered to be hamartomatous malformation rather than true neoplasm and are generally asymptomatic. Here is a case presentation of compound composite odontome with impacted deciduous teeth in an 11-year-old girl. A calcified mass was revealed in the radiograph and the case was finally diagnosed to be compound composite odontome. The mass was surgically excised.

[Isolated canine aplasia in monozygotic twins].

This article describes isolated aplasia of the upper canines with retained deciduous canines in identical female twins. The twins are also concordant in some ectodermal stigmata. As a result of investigating other members of the family it appears that aplasia of the canines is due to a specific autosomal dominant gene.

Dentoalveolar and skeletal changes associated with the pendulum appliance.

The purpose of the study was to examine the dentoalveolar and skeletal effects of the pendulum appliance in Class II patients at varying stages of dental development and with varying facial patterns (high, neutral, and low mandibular plane angles). Specifically, the amount and nature of the "distalization" of the maxillary first molars and the reciprocal effects on the anchoring maxillary first premolars and incisors were studied, as were skeletal changes in the sagittal and vertical dimensions of the face. Pretreatment and posttreatment cephalometric radiographs obtained from 13 practitioners were used to document the treatment of 101 patients (45 boys and 56 girls). The average maxillary first molar distalization was 5.7 mm, with a distal tipping of 10.6 degrees. The anchoring anterior teeth moved mesially, as indicated by the 1.8-mm anterior movement of the upper first premolars, with a mesial tipping of 1.5 degrees. The maxillary first molars intruded 0.7 mm, and the first premolars extruded 1.0 mm. Lower anterior facial height increased 2.2 mm; there was no significant difference in lower anterior facial height increase between patients of high, neutral, or low mandibular plane angles. In patients with erupted maxillary second molars, there was a slightly greater increase in lower anterior face height and in the mandibular plane angle and a slightly greater decrease in overbite in comparison to patients with unerupted second molars. Similar findings were observed in patients with second premolar anchorage versus those with second deciduous molar anchorage. The results of this study suggest that the pendulum appliance is effective in moving maxillary molars posteriorly during orthodontic treatment. For maximum maxillary first molar distalization with minimal increase in lower anterior facial height, this appliance is used most effectively in patients with deciduous maxillary second molars for anchorage and unerupted permanent maxillary second molars, although significant bite opening was not a concern in any patient in this study.
