Abstract: Background: Several therapies have been proposed to treat periimplant inflammatory conditions by removal of biofilm using various methods from exposed implant surfaces. Objective: The aim of this study was to compare possible alterations in titanium surfaces after the use of different treatment methods. Materials and Methods: 40 titanium (machined and SLA) discs were “cleaned” (mimic scaling of an implant surface) using different methods: Conventional Gracey currette, titanium, plastic curettes, SONICflex device (KaVo), Ultrasonic devices (NSK and Cavitron, Dentsply) with special plastic tips, CO₂laser (2W, Pulsed mode), Er:YAG laser (KaVo, at 100 mJ/pulse and 10 pps) and 980nm diode laser (KaVo, 2w power setting, non- contact mode). The disc surfaces were observed using scanning electron microscopy (SEM).

Effects of different root surface cleaning methods on root morphology. A scanning electron microscopic evaluation.

Abstract: Aim: Various methods are available to accomplish the goals of root scaling. The aim of this study was to examine the effects of different root surface cleaning methods on root morphology using scanning electron microscopy. Material and Methods: 14 extracted human teeth were separated into seven groups of two teeth. Each group received 30 seconds of root instrumentation via one of the following: conventional curette (HuFriedy); air scaler (SONICflex, KaVo); ultrasonics A and B (A: Cavitron, Dentsply; B: NSK, Brasseler); Er:YAG laser (KaVo, at 100 mJ/pulse and 10 pps); CO2 laser (DEKA, at 0.5 W and 5 Hertz); and 980nm diode laser (KaVo, at 3 W power, pulse mode). Scanning electron microscopy (SEM) was used to observe morphological changes in root surfaces following instrumentation.

Antinfekční terapie parodontitis
studie Jamal M. Stein, Priv.-Doz., Dr. med. dent., M.Sc.*, Pia-Merete Jervøe-Storm, Priv.-Doz., Dr. med. dent.**
*Universitätsklinikum der Rheinisch-Westfälischen Technischen Hochschule Aachen; **Rheinische Friedrich-Wilhelms-Universität Bonn
Quintessenz Parodontologie 12. ročník, listopad 2011, 16.12.2011

V posledních letech se stále více v parodontologii etabloval pojem „antiinfekční terapie“ a to jako synonymum pro nechirurgickou terapii parodontitis. Označení „antiinfekční terapie“ podtrhuje myšlenku, že při léčbě parodontitis, která se zaměřuje na její příčinu, se jedná o potírání multibakterielní infekce.

Apport des instruments sonique et ultrasonique dans les préparations à visée esthétique
gebruikersrapport  Stéphanie Ortet, Edwige Toca, Hervé Tassery
L'INFORMATION DENTAIRE; No.19; May 2011, 18.05.2011

Quel que soit le type de préparation envisagé, la réalisation d´un congé régulier et lisse reste, pour tout practicien, une étape délicate et pourtant déterminante pour l´adaption précise d´une restauration et pour la pérennité de celle-ci. En effet, la position plus ou moins intrasulculaire d´une limite cervicale et son ajustage influencent directement la santé parodontale et conditionnent le résultat esthétique de nos reconstructions.

Le Fil Dentaire; No. 58; Dec. 2010, 18.12.2010

L´élimination du tartre reste tojours une étape importante quasi-incontournable de tous les typesde traitements parodontaux quels qu´ils soient. La question est de savoir pourquoi, quand et comment procéder au "détartrage" afin d´atteindre les buts fixés conjointement par le patient et le practicien. Ce court article essaie de répondre à ces questions. Il décrit également unse nouvelle technique d´élimination des spicules de tartre pour que les patients et les practiciens soient satisfaits.

A quadrant-design trial of four therapeutic modalities in chronic moderate periodontitis
studie Nonhoff J, Derdilopoulou F, Neumann K, Kielbassa AM
Poliklinik für Zahnerhaltungskunde und Parodontologie, Klinik und Polikliniken für Zahn-, Mund- und Kieferheilkunde, Campus Benjamin Franklin, Charité - Universitätsmedizin Berlin
Schweiz Monatsschr Zahnmed., 01.01.2006

This randomized clinical study (blind and controlled) compared the effectiveness of an ER:YAG laser (combined with a calculus detection system using fluorescence induced by diode laser radiation for use in non-surgical periodontal therapy) as well as sonic and ultrasonic scalers and scaling and root planning with hand instruments to each other.

Heat propagation in dentin during cavity preparation in vitro with oscillating instruments
studie Zesewitz H, Klaiber B, Hotz P, Hugo B
Universität Bern, Klinik für Zahnerhaltung
Schweiz Monatsschr Zahnmed. , 01.01.2005

The purpose of this work was to study the temperature rise caused by preparation of human dentin using two different types of oscillating instruments. A newly designed tungsten carbide tip (Cariex TC, KaVo) and a diamond-coated tip (Cariex D, KaVo) in combination with an airscaler (Sonicflex 2003L, KaVo) and two different flow rates of two coolants were investigated.

A comparative in vitro study of a magnetostrictive and a piezoelectric ultrasonic scaling instrument
studie Busslinger A, Lampe K, Beuchat M, Lehmann B
Clinic for Preventive Dentistry, Periodontology and Cariology, Centre for Dental Medicine, University of Zurich, Zurich, Switzerland
J Clin Periodontol. 2001 Jul;28(7):642-9, 01.07.2001

BACKGROUND: The effects of magnetostrictive ultrasonic instruments and piezoelectric ultrasonic instruments on tooth surfaces seem to differ with regards to root debridement. AIM: The purpose of this study was to compare a magnetostrictive ultrasonic scaling instrument with a piezoelectric ultrasonic scaling instrument and a hand curette regarding time taken, calculus removal, tooth surface roughness (Ra), and SEM examination before and after instrumentation.
