Retrieval of an upper third molar from the infratemporal space.

A case of dislocation of a maxillary third molar into the infratemporal fossa is described. The diagnostic and therapeutic problems are discussed. The tooth was removed through an osseous window that was made in the posterior wall of the maxillary sinus. The healing was uncomplicated, without maxillary sinusitis, and the reduced ability to open the mouth returned to normal. A slight diplopia persisted.

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.

[Intrusion of the definitive incisors].

Intrusive luxations make up about 5% of the dental traumata on permanent front teeth. Clinical and radiological findings are described. Practical guidelines are given for the treatment of intruded teeth, with or without completed root formation, based on literature findings and clinical experience. Much attention is given to the question whether one should prefer orthodontic extrusion or choose for surgical reposition followed by immobilisation in cases of intrusive luxation of teeth with closed apices. Clinical cases are presented.

[Long-term observation of patients with trauma of the lower anterior primary teeth].

Three patients who had had trauma of the lower primary central incisors at the age of 1.5 years or less were observed with regard to the IIIB and/or IVA after eruption of the permanent dentition, and the findings were discussed from the viewpoint of space control. Patient 1 suffered shedding and loss of A perpendicular A following a fall downstairs at the age of 1.5 years. Measurement of the distance between B perpendicular B teeth revealed a tendency toward space closure and decrease until the age of 4 years and 6 months. At the age of 5 years and 11 months, the space was greater than that at the age of 4.5 years. The patient was also found to have brownish, partially parenchymatous defects of the permanent dentition, which were considered to be a sequela. Patient 2 suffered dislocation of A perpendicular A and root exposure at the age of 1 year and 1 month, and received treatment involving restoration and fixation for a 10-day period using a resin splint. Because of a fistula at the apical region of A and a discolored brown with internal resorption revealed by roentgenography, which were observed at the age of 4 years and 10 months, tooth extraction was performed and the course was observed with local space maintenance. When the patient was 6 years and 4 months old, eruption of 1 perpendicular 1 and hypoplasia of the labial surface were recognized. Since it proved possible to preserve A perpendicular A until the patient was 4 years old, the course was observed without any decrease in space until permanent dentition was accomplished. Patient 3 suffered shedding and loss of A perpendicular A at the age of 8 months. When the patient was 1 year and 3 months old, eruption of B perpendicular B occurred with mesial inclination. At the ages of 2 years and 7 months and 6 years and 4 months the patient underwent treatment with a space retainer and eruption of 1 perpendicular 1, respectively, without association of abnormal findings on the labial surface, probably because crown formation of 1 perpendicular 1 had not yet occurred due to the trauma suffered by the patient.(ABSTRACT TRUNCATED AT 400 WORDS)

[Tooth reimplantation].

At the Clinics of Oral Surgery of the Semmelweis Medical University Budapest 16 teeth were reimplanted during the last four years. According to experiences improved by splinting the reimplanted tooth with passive wire arch fastened to brackets, and by filling the root channel with Ca(OH)2. The Favourable therapeutic effect of Ca(OH)2 means impediment of almost always developing resorption.
