[Preventive-curative dental care in a large East German urban population. The 4-year experiences of a Dresden prevention study with 16- to 35-year-old subjects]. / Präventiv-kurative zahnmedizinische Betreuung in einer ostdeutschen Grossstadtpopulation. 4-Jahres-Ergebnisse der Dresdener Präventionsstudie an 16- bis 35jährigen.

The present 4-year Dresden preventive study was carried out to realize a dental care concept with preventive emphasis in 6 Dresden state health services. 2502 patients aged 16-35 years were randomly selected in 1988. The effectiveness of this study was evaluated by means of the parameters oral health behaviour, oral health state and preventive care needs. The spectrum of methods included extended anamnesis, plaque index according to Silness & Löe, DMF/T, DMF/S, GPM/T index, CPITN and saliva tests in case of high caries risk. The dental care based on a basic and a risk strategy. The basic strategy included a complex symptomatic dental treatment and a dental prophylaxis, repeated once every 3 month. The patients were given instruction, demonstration, remotivation, professional oral hygiene measures and topical application of fluorides. The 4-year preventive intervention resulted in an improved consultation and oral hygiene behaviour. The nutritional behaviour did not change essentially. Within the cohort plaque index decreased from 1.01 to 0.68, the GPM/T index from 11.7 to 10.4 as well as the preventive care needs. It was found a low caries increment. The care concept with preventive emphasis is recommendable by its effectiveness.

[The oral health of an East German population of a large city. The basic research of the Dresden prevention study on 2500 16- to 35-year-olds]. / Orale Gesundheit einer ostdeutschen Grossstadtpopulation. Basisuntersuchungen der Dresdener Präventionsstudie an 2500 16- bis 35jährigen.

Oral health behaviour, oral health state, dental care effectiveness and preventive-curative care needs were subject of a basic examination using 2500 randomly selected patients aged 16-35 years in 6 Dresden state health services in 1988. The spectrum of methods included extended anamnesis, plaque index according to Silness & Löe, DMF/T index and DMF/S index according to WHO criteria without X-ray diagnostics, GPM/T index, CPITN, as well as assessment of gingival recessions, acute and chronic trauma and the prosthetic status. Considering a mean DMF/T of 9.88, DMF/S of 17.93 and GPM/T of 11.9 in patients being 16-19 years and a DMF/T of 15.21, DMF/S of 40.94 and GPM/T of 12.9 in patients being 30-35 years, as well as the insufficient dental care, the majority of patients was in need of preventive care measures. Filling therapy and gingivitis treatment were necessary from the curative point of view. Early chronic tooth surface loss required early preventive-curative intervention. The key for an effective care in the early and middle adult age is a functioning individual concept with preventive emphasis which should include a basic and a risk strategy.

[Oral health behavior and state and the effect and necessity of dental care in young and medium adults (Dresden prevention study)]. / Orales Gesundheitsverhalten und Oraler Gesundheitszustand sowie stomatologische Betreuungswirksamkeit und -notwendigkeit im frühen und mittleren Erwachsenenalter (Dresdener Präventionsstudie).

In a baseline examination of a preventive study 319 randomly recruited patients of a dental school aged between 16 and 35 years were inquired about oral health behavior and the oral health state was determined clinically. The spectrum of methods included extended anamnesis, plaque index according to Silness/Löe, DMF/T- and GPM/T-index. The health behaviour and the derived preventive and curative care needs show that the majority of patients need individual oral hygiene and nutrition advising, professional oral hygiene measures, fluoride application, as well as filling therapy. Early therapy of periodontitis is of importance.

[Criteria of high caries risk in the targeted preventive-curative care of 16- to 35-year-olds. The Dresden prevention study]. / Kriterien des erhöhten Kariesrisikos bei der gezielten präventiv-kurativen Betreuung 16-35jähriger. Dresdener Präventionsstudie.

Among 300 patients 16-35-yr-old 21 of them showed a high individual caries risk. Estimation of caries risk was based on the following criteria: caries experience, sugar consumption, fluoride application, dry mouth, plaque accumulation, secretion rate, buffer capacity and S. mutans and lactobacillus counts in saliva. In case of high caries risk a sure diagnosis and directed preventive-therapeutic intervention depend on a complex consideration of all the risk factors.

[The oral health knowledge and behavior as well as the oral findings in young adults with different courses of education (the Dresden prevention study)]. / Mundgesundheitswissen und -verhalten sowie orale Befunde bei jungen Erwachsenen mit unterschiedlichem Bildungsweg (Dresdener Präventionsstudie).

In a dental-psychological investigation 100 young adults, aged 18-25, characterized by different courses of education, were subject to a standardized interview, action oriented diagnostics and dental examination. Knowledge, behaviour as well as state of oral health were different and in all did not come up to our expectations; but there were some correlations. It is indicated to optimize knowledge, behaviour and state of oral health by means of individual and collective measures taking educational specifics into consideration.

[Chlorhexidine in the treatment of root canal infection and its sequels]. / Chlorhexidin in der therapeutischen Trias des infizierten Wurzelkanals und seiner Folgeerkrankungen.

The plaque inhibitor chlorhexidine digluconate was used for intra- and transcanal irrigation in the endodontic treatment triad for periapical lesions (circumscribed, diffuse, fistulating, cystic, suspected cystic lesions). 50 patients were followed up by clinical and standardized radiologic studies. In another 18 patients microbiologic criteria were also used. 16 root canals showed pretreatment infection with mixed aerobic and anaerobic organisms. Mechanical preparation of the root canals with or without extension of the foramen and triple irrigation with 0.5% chlorhexidine digluconate produced clinical relief of symptoms (49 pts.), sterility (14 of 18 pts.) and reduction of the size of periapical lesions (12 pts.). At a mean follow-up of 24 months 30 patients have so far shown complete restitution of periapical bone.

[Transparent dentinal sclerosis and its clinical significance]. / Uber transparente Dentinsklerose und ihre klinische Bedeutung.

Localisation, extension, age dependence and permeability of the translucent zones in different progression stages of the dentine caries were examined by light microscopy, histochemical methods and dye penetration on ground sections, thin-ground sections and decalcified material of extracted human teeth. This phenomenon is observed in every age and more interpreted as a passive chemical precipitation than a protective activity of the pulp-dentine-system. As it is developed incompletely, it represents at most a relative, but not a proof protection from penetrating noxious actions.

[Chronic loss of dental hard substance in early and middle adulthood]. / Chronischer Zahnhartsubstanzverlust im frühen und mittleren Erwachsenenalter.

In a clinical study non-cariogenic chronic dental surface losses were registered in 300 patients, aged 16-35 yr. Nearly in all patients attrition could be stated especially in the anterior tooth area. Wedge-shaped defects occurred in 13% and erosions in 4% of the examined patients. Early recognition, dynamic observation, search for pathogenic moments as well as the preventive and curative early intervention with simple methods are recommended.
