The main goal this research was to find out the effectiveness of the final wash in periapical X-ray films. Spectrophotometry determined the residues of sodium hyposulphite taken as a positive sign for the effectiveness of wash on developed films. Three different kinds of film, two Kodak and one Agfa were used. Films were different sensibility and underwent tests. Two containers, one for the intermediate and other for the final wash were used in the first test; in the second, only one container was used for both washes. A residue of 0.4 mg of sodium hyposulphite was considered acceptable. On the three films used, the acorent of sodium hyposulphite detected was inferior to 0.4 mg in the first test, after 5 minutes exposure, nevertheless the small volume of water used. The second test showed a with range of variation in results and so it not recommend.
