The function of a fixer solution in radiographic film processing is to dissolve and remove the unexposed silver halide crystals from the film emulsion. This process "fixes" the image, making it permanent and preventing the remaining silver from darkening when exposed to light.

Lateral condensation is considered the best method of gutta-percha condensation and is the gold standard technique. Advantages include: 1) Predictable and controllable technique, 2) Excellent apical seal when properly executed, 3) Suitable for most canal configurations, 4) Allows for incremental placement and evaluation, 5) Easy retrieval if retreatment is needed, 6) Well-researched with proven clinical success. While vertical condensation can provide excellent results in skilled hands, lateral condensation is more universally applicable and has the most extensive research supporting its effectiveness.
