Hereditary dentinogenesis imperfecta: a treatment program using an overdenture.

The aim of treatment in cases of dentinogenesis imperfecta is to improve the esthetic appearance and maintain the oral masticatory apparatus in a healthy and functional state. In the growing child, it was decided to maintain the teeth for as long as possible under an overdenture, until such time when a permanent prosthetic solution can be decided upon.

Teenage luxation injury: report of case.

The endodontic, restorative, and orthodontic treatment sequence of the accidental injury of three maxillary incisors has been presented. The treatment objective was to achieve an esthetically acceptable result for a young adult, until a definitive fixed prosthetic restoration can be planned. The ankylosed maxillary right permanent central incisor (11) is being maintained for reasons of arch-length space and alveolar bone height.

A fourteen-year follow-up study of traumatic injuries to the permanent dentition.

The frequency of traumatic injuries to permanent teeth was studied in a Swiss population sample consisting of 262 children. The prevalence of injuries was 10.81 percent. The children (106 girls and 156 boys) ranged in age from 6-18 years; the boy/girl ratio was 1.47:1. The largest number of injuries for boys was found between the ages of 9 and 10 years. The teeth most commonly injured were the maxillary central incisors (80 percent), and the most frequent type of injury was an enamel-dentin fracture without pulp exposure (53 percent). After the emergency treatment, 42 percent of the patients were followed for study from as early as one month up to 9 years. The recall evaluations show that the prognosis was extremely favorable for enamel fractures only, while pulp necrosis developed in 11.8 percent of the enamel-dentin fractures. Fourteen percent of the traumatic injuries were luxation injuries and, of these, 46 percent required endodontic therapy.

Induced root apexification following traumatic injuries of the pulp in children: follow-up study.

Of twenty-five cases presented here, eighteen were boys and seven were girls who required apexification through December 1986. Nine teeth were considered treatment failures after a 9.5-year follow-up period. With these nine cases, however, five teeth to date have had successful endodontic treatment. Additional follow-up time (5-8 years) is required to evaluate the final outcome of pulp canal therapy applied in cases of traumatized maxillary permanent incisor teeth, with incomplete root formation.

The problems of treatment of early ankylosis: report of case.

The case report described in this paper, a patient with an early ankylosed second primary mandibular molar, illustrates the importance of patient cooperation in treatment planning. Extraction too early can cause space loss requiring future orthodontic treatment.

The single maxillary central primary incisor: report of case.

The presented case is a single anomaly not associated with other conditions. In rare cases of the solitary maxillary incisor, the tooth is symmetrical and is always present in the midline, but the crown and root of the tooth are the size of a normal central incisor.

Chin trauma as a cause of primary molar fracture: report of case.

Primary molars can fracture if a severe blow is received on the chin; the fracture can remain undiagnosed, with pain on mastication the only symptom. A case report is described in which an 81/2-year-old boy sustained chin trauma and fractures of primary molars.

Unusual repair capacity following fracture of an incisor: treatment of case.

The events which occurred in this case support the following conclusions: Unusual capacity for repair exists in cases of high crown fractures, if the tooth has not been exposed to the oral cavity. It is advisable to observe further development of the tooth, before deciding on a definite treatment plan.
