There is the need to understand the composition of oral biofilms so that appropriate preventive and treatment regimens, including using appropriate antimicrobials, can be developed further. Additionally, when the systemic effects from specific microorganisms in oral biofilms are better understood, more targeted preventive treatment options may be recommended for persons at high risk for potential systemic diseases such as cardiovascular dis- ease, and for aspiration pneumonia. Hence, the possible association between periodontopathic microorganisms, and also between cariogenic microorganisms in high caries risk persons, and systemic diseases requires further re- search involving metagenomic and large well-designed clinical studies. Effective preventive oral care is important for reducing potential systemic diseases.

This case report describes the diagnosis and endodontic therapy of maxillary fused second and third molars, using cone-beam computed tomography （CBCT）. A 31-year-old Chinese male, with no contributory medical or family/social history, presented with throbbing pain in the maxillary right molar area following an unsuccessful attempted tooth extraction. Clinical examination revealed what appeared initially to be a damaged large extra cusp on the buccal aspect of the distobuccal cusp of the second molar. However, CBCT revealed that a third molar was fused to the second molar. Unexpectedly, the maxillary left third molar also was fused to the second molar, and the crown of an unerupted supernumerary fourth molar was possibly also fused to the apical root region of the second molar. Operative procedures should not be attempted without adequate radiographic investigation. CBCT allowed the precise location of the root canals of the right maxillary fused molar teeth to permit successful endodontic therapy, confirmed after 6 months.

Open journal of Stomatology 2015年第3期5卷 72-79页

作者： Xiaoyu Guo jinhua Yu roger j. smales Huifen Chen Haiyan Si Younong Wu Department of Endodontics Affiliated Hospital of Stomatology Nanjing Medical University Nanjing China School of Dentistry Faculty of Health Sciences The University of Adelaide Adelaide Australia Institute of Stomatology Nanjing Medical University Nanjing China

Objective: To evaluate the effect of different irradiation times on the occlusion of dentinal tubules when using Nd:YAG laser. Background data: Dentin hypersensitivity is a frequent problem that has limited treatment success despite many chemical and physical therapies. Methods: Four coronal dentin disks 2 mm thick were cut with a low-speed diamond saw from four freshly extracted intact first molars. The coronal dentin surface of each disk was divided into four regions, each approximately 2 mm × 3 mm. The dentin surfaces were treated with 27% EDTA then the four regions irradiated separately in a randomized pattern with a Nd:YAG laser (120 mj, 5 Hz), using irradiation times of 0 s, 20 s, 40 s and 60 s, representing laser energies of 0 j/cm2, 200 j/cm2, 400 j/cm2 and 600 j/cm2, respectively. SEM photomicro-graphs were taken at 1500× and 3000× to calculate the dentinal tubule orifice occlusion rates and to measure the tubule diameters, respectively. results: For the laser irradiation times of 0 s, 20 s, 40 s and 60 s, the corresponding dentinal tubule occlusion rates were 2.05 (SD 0.29)%, 10.01 (1.71)%, 23.58 (2.51)% and 90.23 (2.24)%, respectively;and the tubule diameters were 4.18 (0.32) μm, 3.46 (0.24) μm, 1.69 (0.32) μm and 0.12 (0.02) μm, respectively. There were significant differences among all groups for both measured variables (p ≤ 0.005). Conclusions: Within the limitations of this in Vitro study, when using a Nd:YAG laser at 120 mj and 5 Hz, an irradiation time of 60 s achieved the best sealing of the coronal dentinal tubule orifices.

对于一个牙髓病患牙的治疗,可以是根管治疗术加充填修复的传统方法,可以是拔除。拔除后既可采用种植体支持的单冠牙修复,也可以采用固定或活动义齿的修复。究竟选择哪一种治疗方案,取决于患牙部位的许多具体情况,整个口腔的状况以及与患者,医生相关因素。确定治疗方案还应综合考虑远期保存率,成功率,成本-效益,成本-效果等。大量近期文献较为一致的观点是:如果可能的话,根管治疗术加充填修复的传统方法是首选方案。这种治疗方案在日后需要的时候也能改为其他方案。需要复杂治疗,且预后不好的牙齿可考虑拔除。拔除后可以采用种植体支持的单冠牙修复,也可采用2个或3个单位的义齿修复。选择治疗方案时要考虑到近、远期效果,修复体的日常维护以及各种方案所需的费用。这些都必须充分地告知患者。牙科医生在治疗方案的选择时,切忌只考虑经济效益。
