One hundred dry skulls of adult Chinese of both sexes were studied. They were homogeneous in the form of maxillary arch and having full eruption of the upper third molar, without missing teeth and malposition of teeth. Our findings revealed that the mean distance from the center of the greater palatine foramen (GPF) to the midsagittal plane of the hard palate was 16.00 mm, and to the posterior border of the hard palate, 4.11 mm. The location of the GPF related to the maxillary molars was expressed as percentage in 5 relations. We found that the most common location of the GPF was between the maxillary second and third molars (relation III: 48%) and less common was lingual to the maxillary third molar (relation IV: 33.5%). The usually accepted description of the GPF location was lingual to the second molar (relation II), but in our study this relative position occurred in only 17% of the skulls. The long axis of the greater palatine canal directing to the GPF in the oral cavity was found to be directed anteriorly in 181 openings (90.5%) of the 200 GPF, and only 19 openings (9.5%) directed vertically. The bilateral symmetry of GPF on both sides of each skull was remarkable. The discrepancy of our observations on the Chinese skulls from those on other ethnic groups was discussed. Our findings suggest, therefore, the existence of an ethnic variation and the necessity of a more accurate method of locating the GPF in clinical practice.
