Oral-prophylaxe最新文献

Worldwide studies have shown that fissure caries prophylaxis is very difficult using conventional preventive methods. The scientific council of the prophylaxis programme for the protection of mouth and teeth in Vojvodina has begun sealing fissures in Stara Pazova and Novi Sad. The molars of all 6-year-old children were sealed completely. A 77.8% reduction in fissure caries was found at the end of the four-year study. Losses of sealing material came to 16% after four years. Cost-effectiveness analysis: The sealings are three times cheaper than an amalgam filling. Application time: 8-9 minutes.

A caries preventive effect depending on the free fluoride concentration was registrated on rats using dentifrices with NaF or MFP (alone or in combination) despite the presence of CaCO3 as abrasive material because the composition of these dentifrices was changed. The free fluoride concentration of dentifrices had induced the accumulation of fluoride into enamel. The ionized fluoride content of NaF-dentifrices was unchanged for 3 years. MFP was hydrolized and had continuously released fluoride ions. The caries preventive effect which was increased by HCO3- was reproducible in correspondence with the fluoride concentration after the storage for two years.

111 women out of 316 women relaxing in three rest homes volunteered to participate in this study and answered a questionnaire concerning following subjects: daily oral hygiene, knowledge in hygiene procedures, frequency of dental treatment and interest in dental prophylaxis. Oral hygiene behaviour and knowledge were not sufficient. Only half of them knew dental floss and fluorides. Interdental care was practised by 20 women and only 10 used fluorides, they had without exception a secondary education. Most of the participants were educated in dental health care mainly by their parents. 36 women went to see the dentist only in case of necessity. 15 women were very afraid of dental treatment. 60% out of 111 women participated in a lecture on preventive dentistry and prophylaxis.

In order to determine the level of oral hygiene education during pregnancy, 700 questionnaires from 39 hospitals were evaluated. Of the tested persons, 51% had failed to have any dental examination during their pregnancy, although approximately 65% suffered from bleeding, swelling and inflammation of the gingiva. In total 71% received no information regarding oral hygiene during pregnancy. Oral hygiene education during pregnancy either is not provided or at best inadequately available.

The effectiveness of caries diagnosis as seen in bite-wing pictures in the lateral dental segments was evaluated with reference to therapeutic and preventive control. Bite-wing x-rays of 328 patients aged 15-18 were included in the evaluation. The approximal segments from the ist premolars to the 2nd molars were taken into consideration. Further treatment was found to be necessary in 110 patients on the basis of the diagnoses exposed filling edge/split edge (45%), caries in dentine not adjacent to pulp (30%), secondary caries (15%) and caries in dentine adjacent to pulp (10%). Following an initial diagnosis of enamel lesions, preventive measures were necessary in 180 patients. The results document the importance of radiological checks of the permanent teeth in the approximal segments in youths. Bite-wing x-rays are also an effective means of monitoring the effectiveness of preventive measures.

The effectiveness of dental health educational measures in the Federal Republic of Germany is often termed insufficient by specialists. In order to test this statement, a written survey was done with 903 children aged 10-14. Selected results: Most of the school children are of the opinion that what they know is derived from personal communication. Dentists, they say, have been their most important sources of information. Most of the children consider themselves to be sufficiently well-informed, a subjective judgement that cannot, however, be objectively verified by analysis of the answers dealing with concrete knowledge.

In a long-term study of 700 school children attitudes and behaviour related to dental hygiene were registered and collated with findings on caries and oral hygiene. The data indicating developments in the 12 - 14 year old group showed that youths are well informed about the condition of their teeth, but are increasingly unwilling to accept treatment and advice offered by dentists. Potential barriers to compliance with prophylactic and therapeutic measures are a lack of success in school studies, insufficient accentuation of independence in the educational and child-raising process and a lack of communication between dentist and youths.

Caries prevalence and pathological disposition of the gingiva and periodontium in patients with a variety of chronic diseases were investigated in differentiated studies. The results demonstrate the necessity of specific preventive dental measures taking into consideration the concrete pathological situation.

Carious morbidity, oral hygiene, periodontal health, use of fluoride and therapeutic compliance were investigated in a clinical study of 41 children who had previously required insufflation anaesthesia for dental therapy. All of the children underwent postoperative treatment willingly; anaesthesia was not necessary in any of the cases. Half of the children still had a raised risk of caries; gingivitis was present in all of the children as a result of insufficient oral hygiene. For these reasons, all children that have undergone dental therapy under anaesthesia must subsequently be integrated in a programme of selective intensive prophylaxis.
