This was verified by viewing their buccal and proximal radiographs. The external surface of all teeth was cleaned with a periodontal curette. Coronal access was performed with diamond burs.

Efficacy of 4 Irrigation Protocols in Killing Bacteria
Methods: Roots of human teeth were prepared to 25/ 04, autoclaved, and inoculated with Enterococcus faecalis for 3 weeks. Canals were then disinfected by (1) standard needle irrigation, (2) sonically agitating with EndoActivator, (3) XP Endo ﬁnisher, or (4) erbiu-m:yttrium aluminum garnet laser (PIPS) (15 roots/ group).

Selective removal of composite sealants with near
excursions in the pulp chamber of extracted teeth are limited to less than 5ÉC if air-cooling is used during the rapid removal (1 to 2 min) of sealants, water-cooling is not necessary. Selective removal of compos-ite restorative materials is possible without damage to the underlying sound tooth structure.

on extracted teeth. Nevertheless, not all contributions are in agreement. Christo et al.,8 failed to demonstrate an improvement in the use of 0.5% NaOCl in identical biofilms. This disagreement may be a consequence of differences in the power of the laser used. The use of erbium lasers to activate irrigating solutions inside the root canal have
