The temporomandibular joint in ankylosing spondylitis. Correlations between subjective, clinical, and radiographic features in the stomatognathic system and effects of treatment.

One hundred individuals with ankylosing spondylitis (AS) and a comparison group comprising 57 individuals without joint symptoms or disease were studied for correlations between subjective, clinical, and radiographic features in the stomatognathic system and the short-term effect of occlusal splint therapy. There was a correlation between radiographic findings in the temporomandibular joint (TMJ) and subjective and clinical symptoms from the stomatognathic system in individuals with AS but not in the comparison group. There were also more and stronger correlations between clinical signs of TMJ involvement and subjective and other clinical symptoms from the stomatognathic system in the individuals with AS than in the comparison group. There are thus strong indications that the subjective symptoms, the clinical signs, and the radiographic findings in the TMJ of the individuals with AS were caused mainly by this joint disease. The short-term effect of treatment with occlusal splints was investigated in seven of the individuals with AS, who had clinical dysfunction index II or more in accordance with Helkimo. No statistically significant improvement of the subjective or clinical symptoms from the stomatognathic system was found, although a reduction of clinical symptoms was noted in five of the seven individuals.

Radiographic evaluation of endodontic therapy and the influence of observer variation.

In radiographic evaluation of the results of endodontic therapy the development or persistence of periapical radiolucencies often serve as criteria for therapeutic failure. In the present study the influence of inter- and intraexaminer variation on these results was investigated. Three endodontists and three radiologists interpreted periapical conditions and quality of root filling seal in radiographs of 119 endodontically treated roots. Consensus on the presence of periapical lesion was reached in 27% of cases classified as pathologic. In 6% reports of increased width of the periodontal membrane space accorded. The examiners agreed completely on normal periapical conditions in 37% of the cases. On assessing the quality of root filling seal the opinions of observers differed even more. Complete agreement on cases with adequate and defective seal was reached in 25% and 12%, respectively. For the individual examiner the widened periodontal membrane space was the diagnosis most difficult to reproduce. The present study indicates that the large variation noted among clinical and radiographic studies on the results of endodontic therapy could partly be explained by difficulties in defining and maintaining criteria for radiological evidence of periapical disease.

[Colonic occlusions. Retrospective cooperative study of 497 cases].

A retrospective multicenter study involving 12 digestive surgery centers was conducted on 497 cases of colon obstruction. The most frequent cause of colon obstruction was colo-rectal cancer (71 p. cent of cases), but many other etiologies were involved, including 61 cases of torsion and 37 patients with occlusive sigmoiditis. Differential clinical and radiological features in each etiological group are discussed, the results of therapy undertaken analyzed, and a reasonable line of conduct proposed, adapted to each situation, with the objective of attempting to reduce mortality which still affects 25 p. cent of cases operated upon.

Treatment and prognosis of diffuse sclerosing osteomyelitis (DSO) of the mandible.

Twenty-one patients with diffuse sclerosing osteomyelitis (DSO) of the mandible were investigated and treated in Göteborg. Sixteen of these patients ( twelve women and four men) participated in a long-term follow-up study in order to evaluate different therapeutic procedures. Cortisone was found to be a valuable aid to the therapy arsenal. Clinical and radiographic observations are presented. Etiology, therapy, and prognosis of DSO are discussed.

Dental caries and restoration. IV. A six-year longitudinal study of the caries increment of proximal surfaces.

In order to study the progression of proximal caries lesions and the quality of restorations, a sample of individuals in Gothenburg, Sweden was radiographically examined at the ages of 16, 19 and 22. By means of an index system every proximal tooth surface was given a diagnosis and differences between examinations were evaluated by a score system. Of all decayed and filled surfaces observed at the age of 22 more than 70% were already established at the age of 16. During the 16--19 year interval more than twice as many new carious lesions were developed than during the 19--22 year interval. The decrease in the number of new lesions during the last interval was accompanied by a slower progression of already existing lesions. Both factors resulted in a lower mean value with regard to scores during the 19--22 year interval compared with the preceding one. However, great individual differences were noted and 22 percent of the individuals exhibited larger score values during the last interval than during the first. Relatively seen the number of restorations with overhanging margins was lower at the final examination than at the previous ones.

Chronic sclerosing osteomyelitis of the mandible. Scintigraphic and radiographic findings.

Fourteen patients with chronic sclerosing osteomyelitis of the mandible were investigated with 99mTc-labeled bone-seeking agents. Scintigraphic findings were compared with radiographic features. High uptake of diphosphonate and polyphosphate was demonstrated in diseased areas. Good agreement was found between radiography and scintigraphy concerning the extent and activity of each process. The use of bone-seeking radiopharmaceuticals in other types of skeletal lesions and differential diagnostic aspects are discussed.

Condylar fractures of the mandible. II. a radiographic study of remodeling processes in the temporomandibular joint.

Remodeling processes in 76 temporomandibular joints were studied on radiographs from 67 individuals sustaining condylar fractures. The indivuduals were ranged into four age groups: 3-11, 12-15, 16-19, and larger than or equal to 20 years of age at the time of fracture. The radiographic examinations were to be performed at the time of the trauma and 3, 6, 12, 24 and 36-48 months after the injury. In the age group 3-11 there was a complete return to normal skeletal relations in 20 of the 27 joints. Joints in teenagers (12-19) did not become normal to the same extent and in adults only minor remodeling was observed. In children the remodeling of the condylar process was extensive but indistinctly outlined. With increasing age there was a shift towards a more distinct apposition of bone on the posterior part of the condylar head visualized as a double contour. This contour first appeared in the late teens. In adults the remodeling processes seemed only to be part of the functional adjustment. Thus, the remodeling processes of the condylar process in a clinical sense may be looked upon as restitutional in children and adjusting or functional in adults. As regards the articular fossa, in children the remodeling processes were first observed as a double contour, of which the new one became more and more distinct, while the original roof gradually disappeared. The final results was a flattened fossa. In adults, a sclerosis of the roof of the fossa was found.
