[Individually controlled sedation using Midazolam].

Midazolam might be an alternative to general anesthesia for noncooperative children. 40 children were treated during 94 midazolam sedations to evaluate the potential dental therapy. An average of 2 fillings and 1 endodontic treatment was possible per sedation. The initial Midazolam dosage was 0.6 mg/kg. Every 15 min another 0.3 mg Midazolam/kg were administered to maintain the treatability of the children. 30 min after the initial Midazolam dosage dental treatment could be started. The average duration of a sedation was 76 min. Our results suggest that sedations complement under dental treatment general anesthesia.

[Treatment of deciduous teeth under rectal Midazolam sedation].

Individual controlled sedation using Midazolam proves to be a valuable addition to the range of therapeutic options for non-cooperative children. In a clinical study the oral and rectal routes of administration were compared with each other. Rectal application allowed considerably better dose adjustment. While the quality of sedation and the therapeutic range were equal with both routes, rectal application had the advantage that treatment can be commenced sooner. The sedation was of shorter duration and left the patient with less unpleasant memories. Rectal application was easier and required a smaller amount of Midazolam than oral administration.

Dental fear and pain: effect on patient's perception of the dentist.

A questionnaire was developed including the Dental Anxiety Scale (DAS) and the Dental Beliefs Survey (DBS) as subscales to examine the epidemiology of dental fear and dental beliefs in Germany. The survey was administered before treatment to a sample of 474 dental patients. Of the respondents 56% were female. The mean age was 34.3 yr (SD 12.4 yr). The mean DAS score was 8.6 (SD 3.7). Mean DBS score ranged from 1.73 to 2.75 for single items. The correlation between DAS and DBS scores was highly significant (rs = 0.39, P less than 0.001). Absence or presence of dental pain revealed significant differences for DAS and DBS scores (P less than 0.001). Both tests are valid screening forms for the German linguistic context and easy to implement in daily dental routine.

[Interaction of dental treatment anxiety and oral health].

Measurements of oral health (PBI, DMFS), dental treatment anxiety (DAS) and frequency of dental utilization were taken in a sample of 474 dental patients. Regression analysis shows that DAS scores are significantly correlated with DS, but not with MS and FS. Dental anxiety has a negative impact on the frequency of dental utilization, which is a predictor variable of oral health status. These results permit the conclusion that our attention should be focussed on reducing dental treatment anxiety to improve oral health.

[The influence of cavity preparation on the width of marginal gaps in Cerec inlays].

In a study of the influence of the proximal box shape on the marginal fit of Cerec inlays, MOD cavities were prepared in 10 extracted teeth. One box was prepared with sharp edges as recommended by Mörmann (1989), the other was conventionally U-shaped. The width of the marginal gap was measured with a microscope at five different points. The results showed with high significance that the marginal gap of the U-shaped box preparation is smaller. It is recommended to use conventional U-shaped proximal box preparations for Cerec-inlays, too.

[Fine polishing of Cerec inlays using diamond polishing systems].

The surface roughness of Cerec-inlays after polishing with diamond polishing pastes or Diafinish-disks was compared to polishing with aluminium oxide disks (AOD). SEM evaluation of the occlusal surface of extracted teeth revealed that diamond polishing pastes or Diafinish-disks produced smoother surfaces than AOD. The pastes, however, damaged the bonding resin. It is recommended to use AOD and diamond polishing systems for the approximal surfaces of the inlays extraorally. Intraorally AOD or Diafinish-disks are recommended.

[Stress profile during curing contraction of composite resin adhesives].

The wall-to-wall curing contraction of thin composite resin layers was recorded with a tensometer. The composite resin was applied to cylindrically shaped ceramic sample holders with diameters of 3 mm, 4 mm and 8 mm. The distances of the sample holders was set at 50 microns, 100 microns, 150 microns, 200 microns and 300 microns. The shrinkage stress recordings clearly show that the shrinkage forces are governed by the distance of the sample holders and not by the volume or the configuration factor of the composite resin layers.

[Middle course between group and individual preventive programs].

A pilot study was initiated to prove the effectivity of a prophylaxis programme for small groups of preschool children. A total number of 190 children was examined twice a year at the Dental School of Erlangen. The dental examination included df-s index and plaque index according to Quigley-Hein. Tooth cleaning was performed in small groups under professional supervision. Professional plaque removal and local fluoridation concluded each session. Twice a year the parents were offered oral hygiene instructions and informed about the relationship between sugar and caries. After two years the dfs-values were significantly lower in the test group than in the control group. Mean dfs scores ranged from 1.9 for the experimental to 3.8 for the control group. These comparatively low recordings--as against other investigations--may be due to the relatively high social standing of the children.

[Precision of the Cerec-System: the milling unit].

The Cerec-System is a computer-assisted method for fabrication of customized ceramic inlays. Until now there are no data available to judge the precision of this system, which is a function of several variables. This study investigated the tolerance of the milling unit by using computer-constructed data sets for test purposes. REM pictures show how the diamond bur is affected by several milling cycles. Overall precision along the x- or z-axis is largely independent of the inherent properties of the milling instrument used, such as wear. Precision along the y-coordinate, however, is dependent on the number of milling cycles and the feed along the horizontal axis. Best results can be obtained by using a new bur and slow feed.

[The patient--his anxiety and his assessment of the dentist as variables in the compliance model].

The publication concerns the relationship between the two variables "patient anxiety" and "assessment of the dentist by the patient". Two instruments were used: the German versions of the "Dental Anxiety Scale" and the "Dental Belief Survey". The answers of 383 patients, age 18 to 80 years, demonstrated that both tests are highly age dependent. There is no difference between males and females in either test in the overall population nor in the individual age categories. Patient anxiety and assessment of the dentist by the patient show a highly significant correlation.
