摘要

目的:采用分形分析(FA)和像素强度(PI)对接受血液透析的慢性肾衰竭患者(CKFh)、接受肾移植的患者(KT)和无肾病的患者(CG)拔牙后的牙槽骨进行放射学评估和比较:分析了 48 名 CKFh 患者(87 颗拔牙)、12 名 KT 患者(26 颗拔牙)和 29 名对照组患者(76 颗拔牙)在拔牙后 7 天和 60 天的根尖周 X 光片。通过评估分形维度(FD)和PI来评价牙槽骨小梁结构的复杂性和矿物质含量。与 CKFh(0.09 ± 0.10)和对照组(0.15 ± 0.06)相比,KT 患者术后第 7 天和第 60 天的 FD 值差异(0.03 ± 0.08)明显较低。至于 PI 值的差异,KT 组(4.55 ± 10.24)和 CKFh 组(9.88 ± 15.90)的 PI 值明显低于同期的对照组(17.93 ± 11.86)。这些结果表明,与其他组别相比,KT 组患者肺泡中骨小梁复杂性和骨密度的增加较低:结论:与对照组相比,KT 和 CKFh 患者在 X 射线光束平面内骨的整体矿物质含量和厚度较低,这表明在建议这些患者进行种植牙康复治疗时需要慎重考虑。应特别注意 KT 患者口腔康复的潜在挑战。

Alveolar bone healing patterns in chronic kidney failure and kidney transplant recipients: A pixel intensity and fractal analyses.

Aims: To assess and compare radiographically the alveolar bone after tooth extractions in individuals with chronic kidney failure undergoing hemodialysis (CKFh), those submitted to kidney transplantation (KT), and those without kidney disease (CG) by using fractal analysis (FA) and pixel intensity (PI).

Methods and results: Periapical radiographs of 48 CKFh individuals (87 extracted teeth), 12 KT individuals (26 extracted teeth and 29 control individuals [76 extracted teeth] were analyzed at 7 and 60 days after tooth extraction. Fractal dimension (FD) and PI were assessed to evaluate the alveolar trabecular bone structural complexity and mineral content. The difference in FD values between the 7th and 60th postoperative days in KT individuals (0.03 ± 0.08) was significantly lower compared to those of CKFh individuals (0.09 ± 0.10) and controls (0.15 ± 0.06). As for the difference in PI values, KT (4.55 ± 10.24) and CKFh groups (9.88 ± 15.90) showed significantly lower values compared to those of the control group (17.93 ± 11.86) in the same period. These results indicate a lower gain in the trabecular bone complexity and bone density in the alveolus of KT individuals compared to the other groups.

Conclusions: Overall mineral content and thickness of the bone in the plane of the x-ray beam were lower in KT and CKFh individuals compared to controls, reflecting the need for careful consideration in recommending rehabilitation with dental implants for these patients. Particular attention should be given to the potential challenges in oral rehabilitation of KT patients.
