It was associated with poor vision, eye pain and restriction of eye movement of the same eye after 5 hours post left upper molar tooth extraction. The visual acuity in the left eye was hand movement. There was severe ptosis and proptosis of the left eye. The conjunctiva was chemotic with quite anterior chamber. The pupil was mid dilated and sluggished to light. The ocular movement was restricted in all directions. Fundoscopy of the left eye revealed features of central retinal artery occlusion with hyperaemic disc and subretinal exudates at posterior pole. The right eye appeared normal. Urgent MRI brain and orbit revealed severe left paranasal sinusitis with anterior displacement of the left globe and presence orbital abscess. Patient was managed with Otorhinolaryngology and Neurosurgery teams. He underwent emergency transnasal drainage of abscess. Histopathological examination of unhealthy sinus mucosa showed evidence of fungal infection. However, the culture and sensitivity result was inconclusive. Patient was treated with amphotericin B, ceftriaxone, amoxicillin clavulanate and metronidazole. Patient was detected to have high blood sugar level and was managed accordingly. The proptosis improved with treatment. However, his vision, ptosis and ophthalmoplegia remained static. Assessing the immunocompromised status is important for the management of patient presented as acute orbital apex syndrome to avoid fatal outcome.展开更多
目的:观察iRoot BP Plus根尖屏障术治疗慢性根尖周炎伴根尖孔未闭合患者的效果。方法:回顾性分析2022年1月至2024年1月该院收治的84例慢性根尖周炎伴根尖孔未闭合患者的临床资料,依据治疗方案不同将其分为对照组和研究组各42例。对照组...目的:观察iRoot BP Plus根尖屏障术治疗慢性根尖周炎伴根尖孔未闭合患者的效果。方法:回顾性分析2022年1月至2024年1月该院收治的84例慢性根尖周炎伴根尖孔未闭合患者的临床资料,依据治疗方案不同将其分为对照组和研究组各42例。对照组采用三氧化物聚合物(MTA)根尖屏障术治疗,研究组采用iRoot BP Plus根尖屏障术治疗,比较两组治疗效果、临床相关指标(操作时间、术后疼痛时间)水平、治疗前后根尖周指数(PAI)评分和患牙保留率。结果:两组治疗总有效率比较,差异无统计学意义(P>0.05);研究组操作时间、术后疼痛时间均短于对照组,差异有统计学意义(P<0.05);治疗后,两组PAI评分均低于治疗前,且研究组低于对照组,差异有统计学意义(P<0.05);研究组患牙保留率高于对照组,差异有统计学意义(P<0.05)。结论:iRoot BP Plus根尖屏障术治疗慢性根尖周炎伴根尖孔未闭合患者可提高患牙保留率,缩短操作时间与术后疼痛时间,以及降低PAI评分的效果优于MTA根尖屏障术。展开更多

In this case, a 28-year-old female patient took root canal therapy for repeated gingiva tumefaction and tooth stain in anterior teeth of left maxillary and giant foreign body at apex shown in X-ray photography. After removing the foreign body at apex by endodontic surgery, internal bleaching and resin repair were conducted. The therapy shows that the usage specification of hot gutta-percha should strictly follow the operational steps, while the necessity of X-ray photography after operation should be confirmed in clinical operation. In addition, internal bleaching and resin repair should be combined to obtain the success in clinical therapy.展开更多
