Anatomical Drainage Paths of Upper Molars

Imagine a detailed cross-section illustration of a human mouth from a side perspective, highlighting the upper molars. The illustration should be clear, colorful, and designed for dentistry students. Include two visible upper molars with roots and illustrate their draining paths with distinct, colored lines. Trace the vestibular drainage route with a light blue line, starting at the tip of a molar root, extending downwards, passing through the buccinator muscle, and ending at the bottom of the vestibular sulcus, identified by the caption: 'Vestibular Drainage - Ends at the bottom of the sulcus, entering the oral cavity below the buccinator muscle insertion'. The ascending drainage path should be represented with a red line, showing the drainage rising from the root of the upper molar towards the maxillary sinus. Add a cloud or a shaded area in the maxillary sinus indicating the possibility of empyema or sinusitis, accompanied by the caption: 'Ascending Drainage - Can result in empyema of maxillary sinus'. Include a simplified representation of the buccinator muscle and the maxillary sinus for anatomical context and add explanatory captions in Portuguese, with legible, educational font, pointing to the relevant parts of the illustration. Finalize the image with an educational title at the top: 'Drainage Paths of Teeth - Upper Molars'. Ensure the image is friendly, inviting, and educational, suitable to be used as study material or in dentistry class presentations. When generating the image, please ensure all the information is correct and the captions are clear and in Portuguese for student understanding.
