However, limited literature alludes to its prevalence. Troughing procedures may enhance identification, cleaning and shaping. This case report expresses the recognition and management of middle-mesial canal in a mandibular second molar of 24 years old Hispanic-Latino male.展开更多

Materials and Methods: Data from the endodontically treated cases were retrieved, and the patients were recalled for a follow-up appointment at the university. The endodontic diagnosis, radiographs, and the presence of definitive restorations were analyzed in the clinical records. During the follow-up appointment, endodontically treated teeth were classified as present or absent. The nRCT was classified as successful (complete or incomplete healing) or failure (uncertain or unsatisfactory healing). Coronal restoration was classified as absent or present. When it was present, it was classified as permanent or temporary, and its quality as adequate or inadequate restoration. The results were presented as percentages. Results: A total of 257 teeth were endodontically treated. The most prevalent diagnosis was Chronic Apical Periodontitis (33.33%) and the most commonly treated teeth were premolars (46.15%). A total of 52 (21%) treated teeth were clinically and radiographically reexamined. The success rate for the nRCT was 98.08%. About 61.54% of this sample had a definitive composite resin restoration. Conclusion: The nRCT success rate was high. Special attention should be given to the presence and quality of the definitive restoration. Clinical Implications: There was no statistically significant impact between the coronal restoration and the nRCT success (P > 0.05).展开更多
探讨i Root BP Plus根管倒充填联合PRF(platelet-rich fibrin)治疗慢性根尖周病变(chronic periapical lesions,CPL)的临床效果。选取佳木斯市中心医院2020年1月—2022年1月收治的82例CPL患者作为研究对象,依据随机数字表法将其分为观察...探讨i Root BP Plus根管倒充填联合PRF(platelet-rich fibrin)治疗慢性根尖周病变(chronic periapical lesions,CPL)的临床效果。选取佳木斯市中心医院2020年1月—2022年1月收治的82例CPL患者作为研究对象,依据随机数字表法将其分为观察组(n=41,应用i Root BP Plus根管倒充填联合PRF治疗)和对照组(n=41,应用i Root BP Plus根管倒充填治疗),比较两组临床疗效、骨密度、牙周状态、龈沟液炎症因子水平、疼痛情况。结果显示,治疗后,观察组临床治疗总有效率、骨密度高于对照组(P<0.05);治疗后,观察组PD、PBI、TM、PI、CAL、hs-CRP、TNF-α、IL-1β以及总疼痛率低于对照组(P<0.05)。研究发现,i Root BP Plus根管倒充填联合PRF能够优化CPL的治疗效果,改善患者的临床症状,提高患者的骨密度,值得临床推广。展开更多
