Masticatory satisfaction, ability, and performance in partially dentate patients after periodontal therapy

Abstract Introduction Understanding the effects of periodontal therapy is essential in performance and satisfaction of partially dentate patients. Objective To assess the effect of subgingival periodontal treatment in performance and masticatory satisfaction and ability as reported by partially dentate patients with untreated chronic periodontitis. Materials and method Patients were given nonsurgical periodontal treatment and masticatory satisfaction, ability, and performance were evaluated before and after treatment. Performance was assessed based on sieving chewed standardized chewable material, while satisfaction and ability were analyzed using a questionnaire based on OHIP-EDENT. Result Mean numbers of functional tooth units were 10.36 ± 1.43 anterior and 6.73 ± 0.79 posterior teeth. Masticatory performance did not vary significantly (p = 0.075), and mean particle sizes before and after treatment were 4.23 ± 1.84 mm and 3.90 ± 0.75 mm, respectively. Overall satisfaction and ability scores after treatment were higher (p > 0.05) compared with scores prior to the periodontal intervention. Conclusion Periodontal treatment improves masticatory satisfaction and ability with no effect on performance.摘要：了解牙周治疗对部分缺牙患者咀嚼效能与满意度的影响具有重要临床意义。本研究旨在评估未接受治疗的慢性牙周炎部分缺牙患者经龈下牙周治疗后，其咀嚼效能、咀嚼满意度及咀嚼能力的变化情况。材料与方法：本研究对患者实施非手术牙周治疗，并于治疗前后评估其咀嚼满意度、咀嚼能力与咀嚼效能。其中，咀嚼效能通过筛分经咀嚼后的标准化试食材料进行评定；咀嚼满意度与咀嚼能力采用基于口腔健康影响量表-无牙颌版（OHIP-EDENT）的问卷进行分析。结果：功能性牙单位的平均数量为前牙10.36±1.43颗，后牙6.73±0.79颗。咀嚼效能无显著变化（p=0.075）；治疗前后的平均粒径分别为4.23±1.84 mm与3.90±0.75 mm。治疗后的总体满意度与能力评分均高于治疗前（p>0.05）。结论：牙周治疗可改善患者的咀嚼满意度与咀嚼能力，但对咀嚼效能无显著影响。
