(PA: periapical radiography, NM: not mentioned, PPA: parallel periapical radiography, CBCT: cone-beam computed tomography)

Group 1: no contact of tooth apex with the sinus floor, Group 2: at least one tooth root was in contact with the sinus floor without perforating it, Group 3: at least one tooth root was inside the sinus cavity.

Values are presented as mean (range) or mean±standard deviation.
