“…Simulating an extraction therapy case, the first premolars were removed and replaced by canines. The model was divided into two segments, an anterior (teeth 12,11,21,22) and one posterior segment (teeth [13][14][15][16][17][23][24][25][26][27]. The anterior segment was attached to the sensor and the posterior segment to the Stewart platform by a SAM articulator plate and base (SAM Praezisionstechnik GmbH, Munich, Germany) (Figure 1).…”

This study aimed to investigate the dynamic behavior of different torque archwires for fixed orthodontic treatment using an automated, force-controlled biomechanical simulation system. A novel biomechanical simulation system (HOSEA) was used to simulate dynamic tooth movements and measure torque expression of four different archwire groups: 0.017″ x 0.025″ torque segmented archwires (TSA) with 30° torque bending, 0.018″ x 0.025″ TSA with 45° torque bending, 0.017″ x 0.025″ stainless steel (SS) archwires with 30° torque bending and 0.018″ x 0.025″ SS with 30° torque bending (n = 10/group) used with 0.022″ self-ligating brackets. The Kruskal–Wallis test was used for statistical analysis (p < 0.050). The 0.018″ x 0.025″ SS archwires produced the highest initial rotational torque moment (My) of −9.835 Nmm. The reduction in rotational moment per degree (My/Ry) was significantly lower for TSA compared to SS archwires (p < 0.001). TSA 0.018″ x 0.025″ was the only group in which all archwires induced a min. 10° rotation in the simulation. Collateral forces and moments, especially Fx, Fz and Mx, occurred during torque application. The measured forces and moments were within a suitable range for the application of palatal root torque to incisors for the 0.018″ x 0.025″ archwires. The 0.018″ x 0.025″ TSA reliably achieved at least 10° incisal rotation without reactivation.

“…Daher ist eine effektive Keimabtötung im Rah men der endodontischen Therapie unabdingbar [1,2]. Die Bakterienflora im infizierten Wurzelkanalsystem kann zwi schen 10² und 10 7 Bakterien pro Endodont aufweisen [3]. Die Wurzelkanaldesinfektion ist somit ein essentieller Be standteil der systematischen endodontischen Therapie und wird im Zusammenhang mit einer mechanischen Entfer nung infizierten Wurzeldentins und der Formgebung zur Aufnahme eines Wurzelfüllmaterials als chemomechani sche Wurzelkanalaufbereitung bezeichnet.…”

Im Rahmen der chemomechanischen Wurzelkanalaufbereitung haben sich konventionelle Sp?lprotokolle mit L?sungen wie Natriumhypochlorit (NaOCl), Chlorhexidindigluconat (CHX) und Ethylendiamintetraessigs?ure (EDTA) als wirksam gezeigt, die Menge im Kanalsystem vorhandener Bakterien effektiv zu reduzieren. Allerdings konnte gezeigt werden, dass die Wirkung chemischer Desinfektionsl?sungen durch deren Penetrationsverm?gen im Wurzeldentin limitiert ist. Energiereiches Licht in Form von Laserstrahlung ist in der Lage, tiefer in das Hartgewebe einzudringen und auch in diesen Gewebeabschnitten eine Keimabt?tung zu bewirken. F?r den vor kurzer Zeit f?r die Desinfektion in der Endodontie eingef?hrten 445?nm-Halbleiter-Laser wird eine solche Effektivit?t in tiefen Dentinschichten gezeigt werden. Ferner zeigen erste klinische Ergebnisse eine Verringerung der nach konventioneller Sp?lung verbleibenden Keimmenge, sodass die Anwendung der 445?nm-Lasertechnologie eine sinnvolle Erg?nzung konventioneller Desinfektionsprotokolle erwarten l?sst.

“…Almost all conditions that require endodontic treatment are caused by, or later exacerbated by, microbial infections [ 1 ]. Between 10 2 and 10 7 bacteria can be detected in an infected root canal system [ 2 ]. The migration of these bacteria into all parts of the root canal system and also into the surrounding dentin makes it almost impossible to eliminate them completely.…”

Impact of Adjunctive Laser Irradiation on the Bacterial Load of Dental Root Canals: A Randomized Controlled Clinical Trial

Successful root canal treatment depends on the adequate elimination of pathogenic bacteria. This study evaluated the effectiveness of a novel 445-nm semiconductor laser in reducing bacteria after chemomechanical root canal treatment. Microbiological specimens from 57 patients were collected after emergency endodontic treatment, in the following sequence: 1, removal of the temporary filling material; 2, chemomechanical treatment; 3, rinsing with sodium hypochlorite (3%) along with one of three adjuvant protocols (n = 19 in each group). The adjuvant procedures were: (a) sodium hypochlorite rinsing alone (3%); (b) laser irradiation; (c) combined sodium hypochlorite rinsing and laser irradiation. The diode laser was set to 0.59 W in continuous-wave mode (CW) for 4 × 10 s. After the flooding of the root canal with saline, specimens were collected using paper points and analyzed microbiologically. Statistically significant reductions in the bacterial load were observed in all three groups (p < 0.05): 80.5% with sodium hypochlorite rinsing alone and 58.2% with laser therapy. Both results were lower than with the combination of sodium hypochlorite rinsing and 445-nm laser irradiation, at 92.7% (p < 0.05). Additional disinfection of the root canal can thus be achieved with 445-nm laser irradiation after conventional chemical disinfection with sodium hypochlorite solution.
