The application of dental microscope in root canal treatment and retreatment of maxillary first molar
Objective To evaluatethe detection rate, typing, and therapeutic effect of second mesiobuccal canals(MB2) of first molars under dental operating microscope.Methods 88 maxillary molars with the presence of MB2 through cone beam computed tomography (CBCT) were collected, in which 68 were received root...

| description | Objective To evaluatethe detection rate, typing, and therapeutic effect of second mesiobuccal canals(MB2) of first molars under dental operating microscope.Methods 88 maxillary molars with the presence of MB2 through cone beam computed tomography (CBCT) were collected, in which 68 were received root canal treatment and 20 were received root canal retreatment because of the missing canal of MB2 respectively. The type of mesiobuccal root canal in the former 68 maxillary molars were analyzed under CBCT. The 68 maxillary molars were divided into 2 groups, with 34 in each group. The experienment group received treatment under dental operating microscope, while the control group under naked eyes. MB2 detection rate, treatment and retreatment effect between two groups were compared. The latter 20 maxillary molars were also seperated into 2 groups, in which 10 cases were treated under microscope and 10 cases were treated under naked eye. The effect of retreatment was observed.Results The type of mesiobuccal root canal in 68 maxillary molars under CBCT were mainlytypeⅡand typeⅢ, with the proportion of 77.9% (53 cases) and 22.1% (15 cases) respectively. The detection rate of MB2 in the experimental group was 100%, and 91.2% (30 cases) in the control group, a statistical difference can be found between 2 groups (P < 0.05). 97.5% (33 cases) of the experimental group was successfully treated, and 79.4% (27 cases) for the control group (P < 0.05). The success rate of retreatment under microscope was 60% (6 cases), which was significantly higher than that of the naked eye (P < 0.05). In 3-month and 6-month follow-up, the treatment effect in experimental group was significantly better than the control group (P < 0.05).Conclusion Dental microscope can help to increase MB2 detection rate and improve treatment and retreatment effect. |
