The maxillary sinus is an air-filled cavity located above the upper teeth. The roots of the maxillary first molar are typically in close proximity to the floor of this sinus. Due to this anatomical relationship, extraction of the maxillary first molar is the most common dental procedure that can lead to an opening (oroantral communication) into the sinus cavity.

Risk factors for the malignant transformation of oral potentially malignant disorders include the site of the lesion (e.g., floor of the mouth, tongue), size, clinical type (e.g., speckled leukoplakia), presence of Invasive Candida albicans, and DNA aneuploidy. While oral cancer is more common in males, being male in itself is not considered a specific risk factor for the malignant transformation of an existing premalignant lesion. Risk factors relate to the nature of the lesion and associated biological or environmental factors.

The first number in a dental or medical instrument formula indicates the width of the blade or working tip in tenths of a millimeter (0.1 mm). For example, a formula starting with "10" means the blade is 1.0 mm wide. The second number typically indicates the length of the blade in millimeters, and the third number indicates the angle of the blade in degrees.
