A forming apparatus intraoral images comprising: a generator of a pattern of energizable stripes for emitting a light of a fringe pattern quepresenta a particular spatial frequency, using the light emitted in a range of lengths ondade blue light or shorter a polarizer disposed in the path of illumination fringe pattern emitted from delgenerador fringe pattern and having a first axis of polarization transmission, a projection lens disposed to direct illumination fringe pattern polarized as unailuminación incident to a tooth surface, a lens imaging arranged to direct at least a portion of the reflected light and difundidaa from the incident illumination at the tooth surface along a detection path an analyzer disposed along of the detection path and having a second geometric axis ode transmission polarization to provide a polarization polarizer, a detector disposed along the detection path for obtaining data imagenprocedentes light provided through the analyzer yun processor control logic that is responsive to programmed instructions and puedeser driven for image data from the detector and in accordance with data lasimágenes obtained to selectively adjust the intensity of illumination pattern franjassobre the different areas of incidents stripes pattern on the surface of the tooth, it proporcionandocon fringe patterns with sufficient brightness in these different areas to get losdatos images.Un aparato de formación de imágenes intraoral que comprende:un generador de un patrón de franjas energizable para emitir una iluminación de un patrón de franjas quepresenta una determinada frecuencia espacial, usando la luz emitida en un intervalo de longitudes de ondade luz azul o más cortasun polarizador dispuesto en la trayectoria de la iluminación del patrón de franjas emitido a partir delgenerador del patrón de franjas y que presenta un primer eje geométrico de transmisión de polarizaciónuna lente de proyección dispuesta para dirigir la iluminación del patrón de franjas polari
