Data on children with dental trauma who presented for treatment at the Department of Dentistry for Children and Orthodontics in Budapest over a period of 15 years were analysed. The WHO guidelines were used to classify the traumatic injuries. A total of 590 children were involved, 810 teeth being affected. Children aged 7-14 years made up 88% of the cohort. The male:female ratio was 58:42. The permanent:primary ratio for the affected teeth was 90:10. The teeth most commonly affected were the maxillary central incisors. In 70% of the cases, only one tooth was traumatised. The incidence of dental trauma peaked at 10 years of age. The most common injury type observed was enamel-dentin crown fracture. The decreasing sequence of frequency of etiological factors was playing, sports, falls, cycling, road accidents and fighting. Of the accidents, 65% occurred at school or at home. Seventy seven per cent of the patients presented for medical care in the first 3 days after the accident.

The aim of this epidemiological study was to assess the prevalence of malocclusion, associated caries experience, and level of oral hygiene in the Hungarian population using the World Health Organisation (WHO) questionnaire designed to assess dentofacial anomalies. A total of 483 adolescents (289 girls, 194 boys), aged 16-18 years, were assessed. Orthodontic anomalies were detected in 70.4 per cent of the sample. Crowding and spacing were observed in 14.3 and 17 per cent, respectively, with the latter being more prevalent in the maxilla than in the mandible (10.4 and 2.9 per cent, respectively). A Class I occlusion was found in 52.8 per cent of the subjects. A half cusp anomaly in the antero-posterior molar relationship was more prevalent than a full cusp anomaly (26.9 and 20.3 per cent, respectively). The decayed, missing, and filled teeth (DMFT), the decayed, missing, and filled surfaces (DMFS), and the visible plaque indices scores (VPI) of the 340 adolescents with malocclusion were significantly higher (P < 0.05) than those of the adolescents who displayed no anomalies. The prevalence of malocclusion in the Hungarian population seems to be comparable with other European communities.

The aim of the study was to assess caries prevalence in connection with salivary caries–related findings in 349 14– to 16–year–old Hungarian adolescents living in two different cities. DMFT, DMFS means, stimulated salivary flow, buffer capacity, mutans streptococci, lactobacilli and candida counts in saliva were determined. The ratio of caries–free adolescents was 4.6% in the total population sample, DMFT mean values were 7.24±4.86, DMFS means 10.50±8.35. Mean secretion rate of stimulated saliva was 0.84±0.50; a low buffer capacity was found in 6.3% of the examined children. The ratio of carriers of mutans streptococci, lactobacilli and yeasts in saliva was 89.7, 73.9 and 47.7%, respectively. DMFT and DMFS values as well as mutans streptococci and candida counts were lower in the capital than in the other city. Statistically significant correlations were found between DMFT, DMFS mean values, and salivary microbiological counts.

Non-syndromic permanent canine agenesis, or combined with agenesis, or developmental absence of other tooth types, has occasionally been described in the literature, but isolated forms are rarely observed. The purpose of the present retrospective radiographic study was to provide data on the prevalence and distribution of permanent canine agenesis in the Hungarian population. Dental panoramic tomograms and the medical history data of 4417, 6- to 18-year-old children (average age 12 years, male-to-female ratio 1:1), who presented for treatment at the Department of Paediatric Dentistry and Orthodontics of the Semmelweis University Budapest, Hungary, were examined. Patients with systemic diseases were excluded. Chi-square and Fisher's tests were performed to determine statistical significance at a level of P < 0.05. Thirteen subjects had permanent canine agenesis. The overall prevalence was 0.29 per cent. The prevalence of permanent canine agenesis was 0.27 per cent in the maxilla and 0.09 per cent in the mandible (P < 0.01). The male-to-female ratio was 1:2.2. Dental anomalies associated with permanent canine agenesis were found: 11 patients had retention of the primary canines, 10 other types of agenesis of the permanent teeth, one a primary supernumerary tooth, one a supernumerary cusp, and nine occlusal disturbances.

This paper reports the results of a 3-year study on children treated with fixed orthodontic appliances. They were all regularly instructed in oral hygiene maintenance and used a standardized fluoride-free toothpaste during the course of the study. The patients were divided into three groups. Groups one and two, respectively, had a fluoride gel and fluoride fluid (Elmex amine fluoride products, GABA International Ltd, Basle, Switzerland) applied. Group three used only the toothpaste supplied, had oral hygiene instruction, but not topical applications. Caries increments were lowest and gingival health best in the two groups using amine fluorides, especially the gel group.

The levels of salivary lactobacilli and yeasts were determined annually in half of the subjects of the xylitol (X) and fluoride (F) groups of a 3-year caries study. These measurements were carried out with Dentocult (DC) and Oricult (OC) dip-slide methods. A high level of lactobacilli prevailed throughout the study in these subjects. Significant changes were registered in some subgroups--that is, improvement in one of the X institutions and worsening in one of the F and one of the X institutions. At base line the counts of OC were worse in the X than in the F group. In the total material some improvement occurred during the course of the study, mainly in the X group. The changes associated with the preventive program should also be considered as related to the improvement in oral hygiene, restorative treatment, and the mere study effect.

The aim of the study was to establish a preventive program with the combined use of amine fluoride toothpaste and gel in groups of adolescents living in different locations in Hungary. Caries and oral hygiene examinations were performed at the beginning of the study and repeated after 1 and 2 years. The adolescents were divided into 3 groups: 1 control and 2 test groups. The control group continued its usual oral care habits. One of the test groups received Elmex toothpaste for unsupervised home use daily and Elmex gel for use once a week, and the other test group received Elmex toothpaste and only placebo gel. The combined use of amine fluoride-containing toothpaste and gel provided a significant reduction in DMFS mean values (38% including white spot lesions, 34% not including white spot lesions, p < 0.05) and in visible plaque index values (18%, p < 0.05) compared to the control group.
