Introduction The topographic relation between the maxillary teeth roots and the maxillary sinus floor is important for diagnosis and planning of many surgical procedures. The aim of the study was to assess the topographic relationship between posterior maxillary teeth and the sinus floor. Materials and methods 50 pantomographs of patients aged 18-72, treated at the Medical University of Gdańsk, were analysed. We analysed only maxillary molars and premolars. Teeth were assessed using Kwak classification. Statistical analysis was carried out using STATISTICA 13.3. Results We analysed 180 molars and 181 premolars (total 361). According to the root-sinus classification, most of the first molars were type V (55.96%), most of the second molars – type III (32.29%), most of the first premolars – type I (76.09%) and most of the second premolars – type III (35.96%). Non-parametric Spearman’s rank-order correlation coefficient revealed significant correlation between right and left molars and between right and left premolars (p<0.05). Conclusions Proper assessment of the pantomograph allows for correct pre-operative planning, which may affect the course of the procedure and enables to avoid possible complications. These findings may have clinical applications.

Introduction: Third molars (TMs) are the most frequently impacted teeth due to the frequent lack of space in the dental arch resulting in their malposition or inability to erupt. Partially erupted TMs that cause recurrent inflammatory conditions must be removed. The aim of this study was to assess TM position on panoramic radiographs. Materials and methods: We evaluated 200 panoramic radiographs of patients 18-72 years of age. Teeth were assessed in terms of the presence of dental follicle, cervix/root ratio and root development stage. Maxillary TMs were assessed using the Archer and Pell and Gregory classifications, whereas the mandibular ones according to Pell and Gregory, Winter, IAN and Pederson classifications. Results: 622 TMs were assessed. In the maxilla, the most common type was A-positioned, vertically angulated TM with completely formed root/roots. In the mandible, the most common type was A1-positio- ned, mesioangular TM with completely formed root/roots and without enlarged follicle. According to Pederson’s index, 59.44% TMs were moderately difficult to extract. Most roots were in contact with inferior alveolar nerve. Conclusions: The use of the classifications mentioned above is helpful in assessment of the surgery difficulty level. In the long term this allows to increase the predictability of the procedure and minimize the intra- and post-operative complications.
