| Objective To investigate the efficacy of resin nanoceramic Lava Ultimate intrapulpal cementation crowns for restoringshort crown molars in elderly patients with stroke.Methods One hundred and twenty-four elderly stroke patients with short crown molars in Beijing Daxing District Hospital from March 2018 to October 2021 were collected and studied, and assigned into 2 groups according to the restoration protocol, 61 patients treated with zirconia zirconia all-ceramic crowns as the control group and 63 patientstreated with resin nanoceramic Lava Ultimate intrapulpal cementation crowns as the observation group. The United States PublicHealth Service (USPHS) criteria were used to compare the restorative outcomes, microleakage grading, complication rates, pre-prosthetic and 12-month post-prosthetic Oral Health Impact Scale Chinese version (OHIP-14) scores and 12-month post-prosthetic Likert scale scores between the two groups at 6 and 12 months.Results Restoration effect: after 12 months of repair, the marginal fit, color matching, restoration fracture, tooth integrity, and secondary caries pass rate in the observation group were 93.65% (59/63), 93.65% (59/63),96.83% (61/63), 96.83% (61/63), 95.24% (60/63), respectively, which were higher than those in the control group [80.33% (49/61),81.97% (50/61), 83.61% (51/61), 81.97% (50/61), and 83.61% (51/61)] (P<0.05). Microleakage classification: there was no statisticallysignificant difference in the microleakage classification between the two groups at 6 and 12 months after repair (P>0.05). Complications: the complication rate of the observation group was 3.17% (2/63), which was lower than that in the control group [14.75% (9/61)](P<0.05). Oral health-related quality of life: 12 months after restoration, the OHIP-14 scale scores for functional limitations, physiological pain, psychological discomfort, physiological disorders, psychological disorders, and social disorders in the observation group were (1.89±0.57) scores, (2.03±0.62) scores, (0.92±0.30) scores, (0.53±0.18) scores, (0.42±0.10) scores, and (0.63±0.25) scores, respectively,which were lower than those in the control group [(2.55±0.74) scores, (2.73±0.88) scores, (1.29±0.27) scores, (0.74±0.26) scores,(0.31±0.13) scores, and (0.89±0.20) scores] (P<0.05). Satisfaction with repair effect: 12 months after restoration, the self-evaluation of repair effect, satisfaction with complications, and satisfaction with quality of life scores of the observation group were (4.62±0.39)scores, (4.25±0.44) scores, and (4.57±0.40) scores, respectively, which were higher than those of the control group [(4.12±0.35) scores,(3.86±0.35) scores, and (4.03±0.46) scores] (P<0.05).Conclusion Resin nanoceramic Lava Ultimate intrapulpal cemented crown restorations applied to short crown molars in elderly stroke patients are restoratively effective and help reduce complication rates, improve oral health-related quality of life, and improve satisfaction with restorative outcomes. |
