German term or phrase:Handaufbereitung
Aufbereitung gekrümmter Wurzelkanäle erforderte den Einsatz spezieller Techniken, wie z.B. das Vorbiegen und einseitige Abstumpfen der Feilen für Handaufbereitung bis ISO 25.
Hand preparation resulted in the best apical preparation. The use of the Endolift led to fractures of the instruments in four cases and to the worst results in cleaning the walls. With no method the canal preparation was perfect in form and cleanliness. Hand preparation should remain the standard method of root canals preparation. Nevertheless the use of automated devices such as Ultrasonics or the Canal-Finder-System may be helpful in certain strongly limited cases. http://www.ncbi.nlm.nih.gov/pubmed/2630269
The mean time required for manual preparation was significantly (P < 0.001) longer than that required for rotary preparation. Prior experience with a hand preparation technique was not reflected in an improved quality of the subsequent rotary preparation. Approximately 83% of the students claimed to have a greater sense of security in rotary than in manual preparation. Overall 50% felt that manual and engine-driven preparation should be given equal status in undergraduate dental education. CONCLUSIONS: Inexperienced operators achieved better canal preparations with rotary instruments than with manual files. No difference in fracture rate was recorded between the two systems. http://209.85.229.132/search?q=cache:ojXOQNN0bGYJ:www.find-h...
A total of 45 mesial root canals of extracted human mandibular molars were selected. On the basis of the degree of curvature the matched teeth were allocated randomly into three groups of 15 teeth each. In group 1 root canals were prepared to size 30 using a standardized manual preparation technique; in group 2 and 3 rotary NiTi instruments were used following the manufacturers' instructions. Instrumentation time and procedural errors were recorded. With the aid of pre- and postoperative radiographs, apical straightening of the canal curvature was determined. http://209.85.229.132/search?q=cache:iTI9DTQlbIUJ:www.find-h...
