Safety Warnings and SignageThe culminating objective of a successful endodontic treatment is the obliteration of the root canal space and the sealing of the apical foramen at the cementodent1nal junction (1) , with an inert, dimensionally stable, and biologically compatible material (2) .In order to accomplish this in a wide variety of cases the clinician must be competent with more than one obturating technique. Ingle has reported that almost 60% of endodontic failures are apparently caused by incomplete obliteration of the root canal system (3) .A completely filled root canal accomplishes the following:1-Prevents percolation of periapical exudate into the canal space by not allowing for tissue exudate to enter an unfilled portion of the canal where it might stagnate and act as a periapical irritant.2-Prevents reinfection by sealing the root tip from microorganisms present in the periapical tissues or arriving because of a transient bacteremia.3-Creates a favorable biological environment for the process of tissue healing to take place (4) .Regardless of the technique used to fill the canal, it is very essenti~l to remember that a good access cavity preparation and thorough canal debridement and preparation are necessary to achieve a successful three-dimensional seal (5) . No canal filling technique, no matter how 2 advanced, can make up for errors in or lack of complete canal preparation.Because of the demands of patients to retain involved teeth, endodontic treatment has become extremely sophisticated to allow for the retention of a wide variety of teeth to be treated and conditions requiring treatment.If a clinician is married to one simple technique or material, chances then for obtaining this highly desired dense and well-adapted root canal filling in each of these complicated cases is reduced (4) .For many years, gutta-percha has been the most preferred filling material (6) . There are a number of various methods of filling employing gutta-percha, i,e: lateral condensation, vertical condensation of warmed material ( sectional or non-sectional ), the chemically modified gutta-percha, and most recently, the various injectables.Although the most widely used technique (6) , lateral condensation has its detractors. They state that the gutta-percha in the apical portion of the root canal is never condensed against the dentinal walls and a homogeneous, dense mass of gutta-percha is never obtained ( 7 ) •It has been the conclusion of many obse~vers that the long-term effectiveness of teeth filled by lateral condensation of gutta-percha has been very favorable.It is the purpose of this thesis to evaluate simulated prepared canals filled with the lateral condensation technique, using the spectrapoint color coded auxiliary cones in association with different types of sealers, by photographing various levels.
