| 1 | Three-dimensional analysis of the physiological foramen geometry of maxillary and mandibular molars by means of micro-CT显示文摘The aim of this study was to investigate the physiological foramen diameter, shape and distance between physiological and anatomical apex of maxillary and mandibular first and second molars. Accurate knowledge of the physiological foramina morphology; thus, inherent mechanical shaping technical hindrances, is decisive when taking the corresponding root canal final preparation decision. The morphological dimensions of a total of 1 727 physiological foramina were investigated by means of micro-computed tomography. Mean narrow and wide(to a high number, oval) diameters of the physiological foramen were 0.24,0.22 and 0.33 mm and 0.33, 0.31 and 0.42 mm in mesiobuccal(MB), distobuccal(DB) and palatal(P) roots in maxillary first molars; 0.24, 0.22 and 0.33 mm and 0.41, 0.33 and 0.44 in MB, DB, and P roots in maxillary second molars. Mandibular first molars showed mean narrow and wide diameters of 0.24 and 0.30 mm and of 0.39 and 0.46 mm in mesial(M) and distal(D)roots; second mandibular molars showed 0.25 and 0.31 mm and 0.47 mm in M and D roots. The mean distance between the physiological foramina and anatomical apex was 0.82, 0.81 and 1.02 mm and 0.54, 0.43 and 0.63 mm in MB, DB and P roots of the maxillary first and second molars, respectively. A mean distance of 0.95 mm(M) and 1.05 mm(D) in the first and0.78 mm(M) and 0.81 mm(D) in the second mandibular molars was observed. Based on the results obtained, assumable recommendations for final preparation size of the physiological foramen were calculated. However, when taking into consideration, the resulting standard deviations of marginal errors must be cautiously considered when taking a final decision in clinical endodontic treatment. | Thomas Gerhard Wolf Frank Paqué Michael Sven Patyna Brita Willershausen Benjamín Briseno-Marroquín | 2017 | International Journal of Oral Science2017，9，3： | 4 |
| 2 | Root canal morphology and configuration of 123 maxillary second molars by means of micro-CT显示文摘The aim of this study was to investigate the root canal configuration, accessory canals and number of main foramina of 123 maxillary second molars by means of micro-computed tomography. The teeth were scanned and reproduced with 3D software imaging. The root canal configuration and number of main foramina were evaluated by means of a four-digit system. The morphological complexity of human maxillary second molars is depicted by the number of accessory and connecting canals. The most frequently observed root canal configurations in the mesiobuccal root were 2-2-2/2(19.5%), 2-2-1/1(14.6%) and 2-1-1/1(13.0%). A 1-1-1/1 configuration was observed in 93.5% and in 96.7% in the distobuccal and palatal roots, respectively. The MB1 root canal had one accessory canal(18.7%), and 8.9% of the MB2 root canal had one or two accessory canals. The distobuccal(11.3%) and palatal(14.6%) root canals had at least one accessory canal, and connecting canals were observed in16.3% of mesiobuccal roots. The MB1, MB2, distobuccal and palatal root canals had one main foramen in 99.2%, 43.1%,98.4% and 99.2% of samples, respectively. In the mesiobuccal root, one accessory foramen was detected in 14.6%, two were detected in 7.3%, and three were detected in 5.7%. The distobuccal root showed one or two accessory foramina in 9.1% of samples. The root canal configuration of maxillary second molars is quite heterogeneous; the mesiobuccal root has predominantly two root canal entrances(58.4%, 1 in 41.1%) with one main foramen(54.4%). Two main foramina were observed in 43.0%. Morphological variations, connecting and accessory canals were observed in all apical thirds. | Thomas Gerhard Wolf Frank Paqué Anja-Christin Woop Brita Willershausen Benjamín Briseno-Marroquín | 2017 | International Journal of Oral Science2017，9，1： | 3 |
