[Obturation of curved canals: in vitro study of lateral compaction].

The instrumentation and filling of teeth with curved canals are always difficult, therefore, the current study indicates solutions to problems encountered while preparing curved canals. The gutta condensation techniques and their ability to seal curved canals are also discussed. This study uses endodontic simulators to show the incidence of protocols and instrumentation on the ability of the lateral condensation technique to fill curved canals. This study, also, evaluate the lateral condensation technique combined with the thermomechanical in filling curved canals.

[A more efficient lateral condensation].

Advantages and inconvenients of the lateral condensation technique are reviewed in this paper. Different ways to gain more efficient lateral condensation are studied: plugger and gutta-percha points selection and adaptation, combination with thermomecanical technique or assistance by ultrasonic or thermal systems. The study of these various methods and combinations leads to the concept of an thermolateral-assisted condensation.

[Fluoromicroscopy].

The fluorescence is a photoluminescent phenomena consisting in the emission of light under the influence of a light wave excitation. Two types of fluorescence exist: the primary fluorescence (natural) and the secondary (induced by a fluorochrome) The fluoromicroscope is composed of two parts. One of which, unspecific, consists in the classical optical system of the photonic microscopy. The other part, specific, consists in a source of light at a high mercurial pressure and a double filtration system of excitation and pause. There are many applications of this technique. In odontology, it is frequently used for the study of apposition in calcified tissues after their labelling by injection of a fluorochrome.
