- The purpose of this retrospective study (15 years follow-up) was to evaluate the long-term results of treatment to injured teeth following acute trauma. A total of 198 patients with 488 injured teeth were available for analysis. Uncomplicated crown fractures were restored with composite restorations in 106 teeth. 19% of the restorations had been replaced more than 10 times and at the final examination approximately 25% were rated as unacceptable, i.e. needing clinical treatment. Fixed prosthetic therapy had been provided for 106 teeth and endodontic treatment had been provided in 114. Colour changes appearing at late stage suggested obliteration, necrosis or endodontically treated teeth. Anterior composite restorations have been considered acceptable as semi-permanent restorations in patients of early school age (7-15 years), and may have been an advance on what was possible previously, but results of this clinical study suggest that they still do have major shortcomings. There remains a need for a simple, conservative method of restoring aesthetics to fractured and discoloured anterior teeth for clinical use in young patients of late school age.

- The purpose of this study was to investigate histopathological changes in primary teeth following trauma, and to look for possible correlations between the morphology of pulpal calcification and clinical findings. The material consisted of 123 primary teeth from 98 Danish children aged 9-108 months (mean age 33.5 +/- 19.7 months) at the time of injury. The specimens were analyzed by means of light and scanning and transmission electron microscopy. Data from the clinical investigation and from predetermined ranked parameters from the histological analysis were processed in a computerized inductive analysis program. The results, describing patterns of co-variation, are presented as a decision tree. The most common diagnosis was intrusion luxation (54%). In 41% of all teeth, the degree of obliteration was less than 1/4 of the pulpal lumen. In most cases (79%), no denticles were visible. When present, 80% of the denticles had a bone-like appearance. Tissues occluding the pulpal lumen were either dentin-like (49%), bone-like (19%), or fibrotic (9%). It could be concluded that these varying responses could not be correlated with explicit clinical diagnoses. However, in certain combinations, histological parameters could be correlated to clinical findings.

Subjective aspects of patients with traumatized teeth. A 15-year follow-up study.

- The aim of this study was to obtain detailed information about adults who suffered trauma to the teeth as children. A total of 102 patients took part. The patients answered a questionnaire and were interviewed before the oral examination. Thirty-nine per cent of the patients reported dissatisfaction either with the color and/or anatomic form of the traumatized teeth or reconstruction. Most of the individuals did not remember having received any information about prognosis for the traumatized teeth. Twenty-one per cent of the patients remembered pain during treatment, and 25% remembered only the behavior and attitudes of the dental team. It can be concluded that all dental treatment in children with traumatized teeth must be carried out as painlessly as possible, and the dental team should minimize discomfort during the treatment. Good knowledge about traumatology and management can reduce stress and anxiety for both the patient and the dental team.

Caries extreme groups among adolescents, leaving organised dental care in Göteborg, Sweden.

Tidskriftsartikel (refereegranskat)abstract
- The aim was--in a longitudinal respect--to study whether 15-year-old children, in caries-free groups, and groups with high frequency of carious lesions, had a stable caries development from 15 to 19 years of age, when they left the organised Public Dental Care. Caries index values were analysed for the period 1986/7-1990/1 for patients born 1971-72 and residing in Göteborg. The groups of caries-free children seemed to be stable in their dental health in about 60-70% according to the prevalence indices used; and about 80% according to the incidence index DS-a. The caries prevalence index mean values of the 15-year-old patient groups with high frequencies of lesions showed between 1.5 to 3.5 percentile units higher mean values when the individuals were 19 years of age. However, the corresponding caries incidence index values were as low as half the size, indicating a possible treatment effect of the caries prevention programme used. Related to the DFS-a index, the 20% groups with the highest caries index values were registered for about 80% of all approximal lesions, of special interest for dental care costs.

On longitudinal caries index data. A comparison study between cohort and cross-sectional attempts.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present study was to compare registered data of caries prevalence and incidence from cross-sectional studies of specified age groups with the corresponding caries data from cohorts of individuals receiving dental health service from the same dental clinic during the years studied. The study covered two 15-19-year groups, who had been offered complete dental care from three years of age in the City of Göteborg for the time periods 1986/7-1990/1. When compared, the longitudinal cohort attempts often gave statistically significant different values to those of the cross-sectional year classes, which should be considered when presenting caries index mean values in dental health reviews. It is not indifferent to choose between longitudinal cohort and cross-sectional year class attempts when searching for dental health treatment effects. Due to the advantages of using longitudinal cohort study methods, and with regard to the differences of the study design used, as pointed out in the study, the use of longitudinal cohort patient material, extracted from cross-sectional epidemiological data bases, could favour analysis of the effects of different preventive dental care programs.
