[Patient ombudsmen at the Rikshospitalet. Experiences with a 2-year trial].

A patient-ombudsman has been engaged in some somatic hospitals in order to improve the level of legal protection. This article deals with a two-year experiment at Rikshospitalet (The National University Hospital). Formal complaints against the hospital increased dramatically as a result of the presence of the ombudsman. Many more patients' complaints were assessed by medical experts. Hospital routines were also changed. The owner had to pay much more to patients who claimed damages. The executive work in the health service was not effective. It took a long time to process the claims for compensation, to reach a decision on proper and correct application of the law, and to actually pay the compensation. Patients and hospital staff alike evaluated the experiment positively. It has not yet been decided whether the arrangement should be established permanently.

Observer strategy and the radiographic classification of healing after endodontic surgery.

An observer strategy involving trained and experienced examiners was used in a large series of endodontic surgery cases, evaluated radiographically 1 year after the operation. The cases were grouped in 1 of the following 4 healing groups; complete healing, incomplete healing (scar tissue), uncertain healing and unsatisfactory healing (failures). The radiographs were first examined separately by an oral surgeon and an endodontist. Deviating cases were subjected to joint evaluation. The overall agreement before joint interpretation was satisfactory: 63% when corrected for chance agreement. Agreement after joint evaluation reached 94% of the total material. Disagreement and difficult borderline cases were judged by an oral radiologist. He was more pessimistic than the 2 main examiners. The identification of healed cases with apical bone which had not yet obtained normal radiopacity and structure was difficult. Altogether, the observer consistency was satisfactory; the selection of experts increased the chances of "true" diagnoses; the important screening function of the one-year control was confirmed. The applied strategy and the classification are recommended for follow-up studies.

Overextended gutta-percha and Kloroperka N-O root canal fillings. Radiographic findings after 10-17 years.

A representative sample, 55%, of the patients treated endodontically by undergraduate students in a teaching clinic during the years 1963 to 1969 were reexamined 10-17 years later. Gutta-percha/Kloroperka-NO root fillings (282), classified as having surplus material at the time of treatment, were evaluated in follow-up radiographs. In about 80% of the cases of overfilling, no excess root filling material could be traced at the reexamination. In a few cases only, the appearance of the excess material was nearly identical to that at the time of treatment, whereas the remaining overfillings (18%) showed a reduced size. Among the recorded variables only one seemed to have a major impact on the prognosis--namely, the presence or absence of an apical radiolucency at the time of treatment, indicating that infection was the important factor when failures occurred. Apical overfilling per se had little influence on the long-term healing result as judged radiographically.

Number of teeth and tooth loss of former dental school patients. Follow-up study after 10-17 years.

Persons (n = 431) who had received endodontic and other treatment at the School of Dentistry in Bergen in the 1960s were invited to attend an examination in 1980, some 10-17 years after their first course of treatment. The age range initially had been 16-55 years. The attendance rate was 55% (149 women and 89 men) and was higher for the older age groups. Data from pre- and post-treatment records were added to the information obtained in 1980. Those who attended in 1980 had had 22.8 teeth at the initial examination and 21.2 teeth after their first course of treatment in the 1960s. In 1980 they had 19.3 teeth. About 20% of the persons had the same number of teeth at all three examinations, and 43% had not lost teeth after completing treatment at the school. Molars and maxillary teeth were most likely to have been extracted. This was also the case for teeth lost during the first course of treatment. Some 4% of the individuals had become edentulous. Conventional dental treatment had not prevented further tooth loss; the number of remaining teeth within each age group was about the same in 1980 as in the 1960s.

The apical level of root fillings.

The apical level of root fillings made by general practitioners, undergraduate students and an endodontist was compared. In total, 3003 root fillings were grouped morphometrically in three classes. Class A fillings were ending at a distance from the radiographic apex. Class B fillings were ending flush with the radiographic apex or with an overfilling of not more than 1 mm, while class C consisted of fillings with a moderate (1-2 mm) or marked (greater than 2 mm) excess. For 2187 class A fillings the distance from the apical end of the root filling to the radiographic apex was measured to the nearest 0.5 mm. The 531 class B and 285 class C root fillings were given the distance 0.0 mm. A detailed classification of root fillings with regard to their length was then developed by calculating the average distances and standard deviations. A longer apex-distance was observed for root fillings made by the general practitioners than for those made by the undergraduates and the endodontist. Class B and C fillings were infrequently observed among fillings made by general practitioners. Roots from three-rooted teeth had been filled closer to the radiographic apex by the endodontist than by undergraduates. A higher relative number of class C fillings was observed for undergraduates than for the endodontist, while the opposite observation was made for class B cases.

Tooth mortality and endodontic status of a selected population group. Observations before and after treatment.

Tooth mortality and the frequency and distribution of endodontically treated teeth was studied in a Norwegian population group. The pre- and posttreatment situation was thus surveyed in 481 individuals with endodontic treatment. The middle aged and the female patients were overrepresented in the sample. At admittance the mean number of teeth per patient was 22.8, 2.6 of which had been endodontically treated. After comprehensive dental treatment, the corresponding figures were 21.5 and 3.7. During treatment extractions were performed in 48% of the patients, twice as often in the maxilla as in the mandible, 47% of the extracted teeth being molars. At admittance, root fillings comprised 83.5% of the total number of endodontically treated teeth, while pulpotomies were observed in about 15%. Retreatments were performed in 35% of the treated roots and in every other patients.
