Abstrakt:	Background: The palatal surface of the maxillary anterior teeth in conjunction with the incisal edge represents the mechanical area, which is of great importance for lateral and anterior guidance. Therefore, in terms of restorative dentistry, it is crucial for the clinician to have a detailed knowledge of the palatal surface anatomy (PSA) of the different maxillary anterior teeth in order to reestablish a definitive correlation between form, function, and esthetics. The aim of the present study was to analyze the variations in the PSA of the maxillary central incisors (CIs) and their correlation with tooth form and gender. Materials and Methods: Impressions of the maxillary arch of 500 study participants were taken and then classified according to PSA and tooth form. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) software. The chi-square test was utilized for comparisons among PSA, tooth form, and gender of the participants. Results: The results showed Type 5 to be the most common PSA in maxillary CIs and the square tooth form to be the most common tooth form among both genders; Type 5 was also found to be the most common PSA within the square tooth form.
