Prevalence of molar-incisor-hypomineralisation (MIH) among 6-12-year-old children in Central Hesse (Germany).

AIM: The aim of the present cross-sectional study was to assess and compare the prevalence of MIH among 6-12-year-old school children living either in a rural area of Central Hesse (Germany) or in the city of Frankfurt on the Main (Germany). A possible association between hypomineralised second primary molars (HSPM) and MIH was investigated. Furthermore, the MIH prevalence data of the rural area were compared with those of a previous study conducted in this area in the school year 2002/2003. METHODS: In the school year 2014/2015, 2103 children (6-12 years of age) were examined during the annual school-based dental examinations prescribed by law at nine schools in the rural area of Central Hesse (LDK) and five schools in the city of Frankfurt on the Main (Ffm). Eight previously calibrated dentists working for the public healthcare authorities assessed the prevalence of HSPM/MIH (EAPD criteria/severity scale by Wetzel and Reckel) and the caries experience (dmft/DMFT). RESULTS: The prevalence of HSPM/MIH amounted 3.2%/9.4% in LDK and 2.9%/17.4% in Ffm. In the majority of cases, children with MIH had demarcated opacities. In LDK, hypomineralised first permanent molars were most commonly affected by severity degree 2, whereas in Ffm, severity degree 1 was predominant. Children suffering from HSPM had an odds ratio of 11.32 (95% CI: 6.73-19.03) for having MIH as well. Compared with the results of 2002/2003 in LDK (prevalence of MIH 5.9%), the MIH prevalence increased by 3.5% in the rural area. All in all, the caries experience among children under investigation was low (DMFT 0.14-0.15). SIGNIFICANCE: MIH may be diagnosed in school children living in different areas of Germany with regional variations (rural-urban comparison). The presence of HSPM is of predictive value for MIH. The increasing number of hypomineralised first permanent molars over 12 years of time in the rural area indicates a need for further investigation on the aetiology of MIH.

[Overweight in primary school-age children. Prevalence and risk factors]. / Gewichtsentwicklung im frühen Grundschulalter. Prävalenz, Inzidenz und Risikofaktoren für Übergewicht und Adipositas.

BACKGROUND: Various studies show that pre-school age is a sensitive period for the development of overweight and obesity. During a longitudinal study between 2010 and 2013, the municipal health authority (city of Frankfurt) in cooperation with the university children's hospital investigated the development of weight in children aged 5 to 8. MATERIALS AND METHODS: The weight and height of a collective of 5720 children were measured (2010/11). In addition, nutritional and exercise habits, as well as media consumption was documented for 4758 children through a questionnaire during the school enrolment procedure. The weight and height of 3481 children were measured again in the second grade (2012/13). RESULTS: Over a period of 24 months, the percentage of overweight (not obese) children increased from 7.5 to 9.4 % and that of obese children from 4.5 to 5.0 %. 164 of 2818 children with a normal initial weight (5.8 %) changed to percentile class overweight or obese. 79 of 260 children who were initially overweight, not obese (30 %), changed to the group of normal weight, but only 4 out of 156 obese children (3 %). Increased TV consumption (> 1 h per day), availability of their own television, lack of physical activity, and consumption of high-calorie drinks were risk factors for the development of overweight during the primary school age. 72 % of parents of overweight children and 22 % of obese children falsely classified their children as normal weight. CONCLUSIONS: Targeted education about the risk of obesity in the primary school age and offers for early intervention should be established in the healthcare services concerned.

[Oral health hygiene education programme for nursing personnel to improve oral health of residents in long-term care facilities 2010 in Frankfurt/Main, Germany]. / Schulung von Pflegepersonal in Altenpflegeheimen zur Verbesserung der Mundhygiene bei den Bewohnern - Interventionsstudie in Frankfurt am Main 2010.

BACKGROUND: Many studies have shown the urgent need for improving oral health hygiene in nursing home residents. Deficits in the knowledge of the personnel about dental and oral hygiene are often cited as one of the causes. Therefore, an oral health education programme was provided to the personnel of 20 nursing homes in Frankfurt/Main. Here the results of the assessment of the impact of the education programme on knowledge and attitudes of the personnel as well as on oral health of the residents are presented. METHODS: In May/June 2010, 471 nurses in 20 nursing homes in the Frankfurt/Main, Germany, received a two-hour education programme on oral health. The lessons were held by dentists with special education in geriatric dentistry. The personnel were asked to complete a questionnaire regarding knowledge and attitudes on oral health care before the education programme and 4-6 months afterwards. The oral health status of 313 residents (i. e., about 10% of the total residents) was examined by two dentists. Before and 4-6 months after education of the caregivers, the following data were recorded in the residents: number of teeth, caries, plaque index (PI), sulcus bleeding index (SBI), community periodontal index of treatment needs (CPITN) and denture hygiene index (DHI). RESULTS: By attending the lessons, good improvements in knowledge of the caregivers could be obtained. The education programme was rated as very good/good by 85% of the nurses, having reduced their fear of oral care in the seniors and having gained more competence in practical oral hygiene procedures. Mean age of the residents was 80±13 years. About 32% of the residents were edentulous. Teeth were carious in 53% of the residents. Initially, one half of the residents exhibited plaque index>2, in 29% of the residents a severe and in 59% of them a very severe parodontitis was found (CPITN 3 or, respectively, 4). At 4-6 months after the education programme, an improvement in oral and dental hygiene of the residents could be demonstrated, significant for plaque index, cleanliness of the tongue and denture hygiene index. CONCLUSION: The positive assessment of the nursing personnel as well as the positive effects on oral hygiene in the residents are in agreement with the results of many other studies in many countries. Therefore, these education programmes will be continued in the long-term care facilities in Frankfurt/Main, Germany.·
