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
引言：了解牙周治疗的效果对于部分缺牙患者的咀嚼效能与满意度至关重要。
研究目的：评估龈下牙周治疗对未经治疗的慢性牙周炎部分缺牙患者所报告的咀嚼效能、咀嚼满意度及咀嚼能力的影响。
材料与方法：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、咀嚼能力及咀嚼效能。其中，咀嚼效能通过筛分经咀嚼后的标准化咀嚼物料进行评估，咀嚼满意度与咀嚼能力则采用基于口腔健康影响量表-无牙颌版（OHIP-EDENT）的调查问卷进行分析。
结果：功能性牙单位均值为前牙10.36±1.43颗，后牙6.73±0.79颗。咀嚼效能无显著差异（P=0.075），治疗前后的平均颗粒粒径分别为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牙周干预前（P>0.05）。
结论：牙周治疗可提升咀嚼满意度与咀嚼能力，但对咀嚼效能无显著影响。
