Background

Although objective and subjective masticatory function measures may correlate, associated oral health–related factors may differ, highlighting the need for comprehensive assessment to support tailored care in long-term care facilities (LTCFs).

Objective

To investigate the association between objective and subjective masticatory function and the oral health status of older LTCF residents in Brazil.

Materials and Methods

This cross-sectional study included 187 residents (mean age = 78.7 ± 9.2 years) from nine LTCFs. Masticatory function was evaluated objectively (bi-coloured chewing gum) and subjectively (‘Do you have trouble biting or chewing any kind of food?’). Oral health status was assessed by self-perceived oral health, the number of natural teeth and posterior occluding pairs (POPs), xerostomia and dental prosthesis requirement. Data were analysed using multiple regression (α = 0.05).

Results

Objective and subjective masticatory function were associated (p < 0.001). Older age (p = 0.006), low number of natural teeth (p = 0.001) and POPs (p = 0.004) and the dental prosthesis requirement (p = 0.016) were associated with poorer objective masticatory function. Poor self-perceived oral health (p = 0.001), low number of POPs (p = 0.013), severe xerostomia symptoms (p = 0.001) and dental prosthesis requirement (p = 0.030) were associated with poor subjective masticatory function.

Conclusion

Objective and subjective masticatory functions were associated and shared some common factors, number of POPs and the need for dental prostheses. However, objective measures (e.g., number of teeth) were linked to objective masticatory function, whereas self-perceived factors (e.g., perceived oral health and xerostomia) were associated with subjective masticatory function.

背景：虽然客观和主观咀嚼功能测量可能相关，但相关的口腔健康相关因素可能不同，强调需要进行全面评估，以支持长期护理机构（ltcf）的量身定制护理。目的：探讨巴西老年LTCF居民主观、客观咀嚼功能与口腔健康状况的关系。材料和方法：本横断面研究包括来自9个ltcf的187名居民（平均年龄= 78.7±9.2岁）。对咀嚼功能进行客观评估（双色口香糖）和主观评估（“你在咬或咀嚼任何食物时有困难吗？”）。通过自我口腔健康、自然牙和后牙对（pop）数量、口干症和义齿需求来评估口腔健康状况。数据采用多元回归分析（α = 0.05）。结果：客观咀嚼功能与主观咀嚼功能存在相关性(p)。结论：客观咀嚼功能与主观咀嚼功能存在相关性，存在一些共同的因素，如持久性有机污染物（POPs）的数量和修复体的需要量。然而，客观测量（如牙齿数量）与客观咀嚼功能有关，而自我感知因素（如感知口腔健康和口干）与主观咀嚼功能有关。

Background

Handgrip strength (HGS) reflects overall muscular fitness and health. Although associations between absolute or BMI-adjusted HGS and systemic conditions have been studied, no research has examined its link to tooth loss using modified relative HGS indices from other anthropometric factors.

Objectives

This study aimed to investigate, for the first time, the association between tooth loss and various modified relative HGS indices using nationally representative data.

Methods

Using the 2014–2023 Korean National Health and Nutrition Examination Survey data (n = 52 206), relative HGS was calculated by adjusting dominant HGS with various body indices. Oral status was classified as functional (≥ 20 teeth) or reduced (< 20 teeth). Statistical analysis to assess associations and diagnostic accuracy was performed using the chi-square test, t-test, incidence rate ratio (IRR), and the receiver operating characteristic (ROC).

Results

In the fully adjusted IRR analysis, waist circumference (WC)-based relative HGS showed the strongest inverse association with tooth loss (IRR = 0.505, 95% confidence interval [CI] = 0.388–0.656). The ROC analysis revealed that relative HGS indicators adjusted for WC, waist-to-height ratio (WHtR), and weight-adjusted waist index (WWI), which represent central adiposity, had the highest diagnostic accuracy for predicting tooth loss (area under the curve [AUC] = 0.6367, 0.6323, and 0.6316, respectively). Significant differences were observed in all HGS indicators based on the functional dentition criterion (p < 0.001).

Conclusion

WC-adjusted relative HGS showed the strongest inverse association with tooth loss, indicating its potential utility for early identification of high-risk individuals and informing multidisciplinary approaches to oral rehabilitation.

背景：握力（HGS）反映了整体肌肉的健康状况。虽然已经研究了绝对HGS或bmi调整后的HGS与全身状况之间的关系，但没有研究使用其他人体测量因素修正的相对HGS指数来检查其与牙齿脱落的联系。目的：本研究旨在首次利用具有全国代表性的数据，探讨牙齿脱落与各种改良的相对HGS指标之间的关系。方法：利用2014-2023年韩国国民健康与营养检查调查数据（n = 52 206），通过调整优势HGS与各种身体指标，计算相对HGS。结果：在全校正IRR分析中，以腰围（WC）为基础的相对HGS与牙齿脱落呈最强的负相关（IRR = 0.505, 95%可信区间[CI] = 0.388-0.656）。ROC分析显示，代表中心性肥胖的WC、腰高比（WHtR）和体重调整腰围指数（WWI）调整后的相对HGS指标预测牙齿缺失的诊断准确率最高（曲线下面积[AUC]分别= 0.6367、0.6323和0.6316）。基于功能牙列标准的所有HGS指标均存在显著差异(p)。结论：wc调整的相对HGS与牙齿脱落呈最强的负相关，表明其在早期识别高危个体和为口腔康复提供多学科方法方面的潜在效用。

Aim

To explore the direct and indirect pathways through which sociodemographic, psychological, behavioural, and clinical factors influence sleep bruxism (SB).

Methods

This cross-sectional study was conducted with a sample of 686 adults (mean age of 50.1 years; 380 female and 306 male), from a total of 712 individuals from the Sao Paulo Epidemiological Sleep Study (EPISONO) follow performed in 2015. SB was assessed using self-report, overnight polysomnography (PSG-based), and combined methods. Sociodemographic, psychological, behavioural and clinical factors were assessed. Structural Equation Modelling was used to examine the pathways between potential risk factors and SB.

Results

From an initial sample of 1042, 712 returned for follow-up and 686 individuals were eligible based on the SB outcomes evaluated and having undergone PSG. The SB self-reported prevalence was 17.1%, 30.5% presented PSG-based SB and 7.4% in combination of methods (self-report+PSG). Sleep bruxism (assessed by all methods) was directly associated with higher levels of insomnia and younger age. Higher socioeconomic status was directly associated with self-reported SB, whereas PSG-based and self-report+PSG SB were associated with increased obstructive sleep apnea and smoking. Regarding indirect effects, elevated anxiety and depressive symptoms indirectly impacted all forms of SB via increased insomnia levels.

Conclusions

Our findings highlight distinct and overlapping pathways of SB. Insomnia and younger age consistently predicted SB, while psychological factors indirectly impacted SB via insomnia. Demographic, behavioural, and clinical factors showed direct associations that varied according to the assessment method.

目的：探讨社会人口学、心理、行为和临床因素影响睡眠磨牙症的直接和间接途径。方法：本横断面研究的样本为686名成年人（平均年龄50.1岁，女性380人，男性306人），来自2015年圣保罗流行病学睡眠研究（EPISONO）的712名个体。采用自我报告、夜间多导睡眠图（PSG-based）和综合方法评估SB。对社会人口学、心理、行为和临床因素进行了评估。结构方程模型用于检查潜在危险因素与SB之间的途径。结果：从1042个初始样本中，712人返回随访，686人根据SB结果评估并接受了PSG治疗。自我报告的SB患病率为17.1%，以PSG为基础的患病率为30.5%，联合方法（自我报告+PSG）的患病率为7.4%。睡眠磨牙症（通过所有方法进行评估）与较高程度的失眠症和更年轻直接相关。较高的社会经济地位与自我报告的SB直接相关，而基于PSG和自我报告+PSG SB与阻塞性睡眠呼吸暂停和吸烟增加相关。关于间接影响，焦虑和抑郁症状的升高通过增加失眠水平间接影响所有形式的SB。结论：我们的研究结果强调了SB的不同和重叠的途径。失眠和年轻一致地预测SB，而心理因素通过失眠间接影响SB。根据不同的评估方法，人口统计、行为和临床因素显示出不同的直接关联。

Background

From the perspective of site specificity, inducing muscle activity across a large area of the tongue through diversified tongue resistance training (TRT) may be an effective approach to improve tongue pressure (TP) and function. However, the distribution of muscle activity within the tongue during different TRT exercises remains unclear.

Objectives

To examine the hypothesis that muscle activity distribution within the tongue varies with TRT direction using muscle functional magnetic resonance imaging (mfMRI), and to clarify the relationship between these distributions and functional outcomes.

Methods

Twenty young volunteers were randomly assigned to either an elevation or a lateral 4 week TRT group. We performed mfMRI before (at rest) and immediately following each training task, before and after 4 weeks of TRT, and we measured maximal elevation, lateral TP, and oral diadochokinesis (ODK). A linear mixed-effects model was used to analyse the functional outcomes.

Results

After TRT, mfMRI revealed that elevation exercise activated the anterior tongue, including the origin of the genioglossus. Conversely, lateral exercise induced significant activity across a wider area extending to the tongue root. Post-training maximal elevation TP and overall ODK values were significantly higher in the elevation training group. No significant differences between groups were observed in post-training lateral TP.

Conclusions

TRT direction changes the pattern of muscle activity in the tongue. This finding reveals qualitative aspects of TRT that cannot be evaluated by post-training TP alone, offering a new perspective for designing more effective rehabilitation programs.

背景：从部位特异性的角度来看，通过多样化的舌阻训练（TRT）诱导大面积舌肌活动可能是改善舌压（TP）和功能的有效途径。然而，在不同的TRT练习中，舌头内肌肉活动的分布仍不清楚。目的：利用肌肉功能磁共振成像技术（mfMRI）检验舌内肌肉活动分布随TRT方向变化的假设，并阐明这些分布与功能结局之间的关系。方法：20名年轻志愿者被随机分配到抬高组或侧边4周TRT组。我们在每次训练任务之前（休息时）和之后，在4周TRT之前和之后进行了mfMRI，并测量了最大仰角、外侧TP和口腔运动失调（ODK）。采用线性混合效应模型分析功能结果。结果：在TRT后，mfMRI显示抬高运动激活了前舌，包括颏舌肌的起源。相反，横向运动则会在更大范围内诱发显著的活动，一直延伸到舌根。训练后最大仰角TP值和总ODK值均显著高于仰角训练组。两组间训练后侧TP无显著差异。结论：TRT方向改变舌部肌肉活动模式。这一发现揭示了单纯通过训练后TP无法评估的TRT的定性方面，为设计更有效的康复方案提供了新的视角。试验注册：ClinicalTrials.gov标识符：UMIN000047658。

Background

Studies on painful temporomandibular disorders (TMDs) and somatic symptoms in Southeast Asian migraine patients are lacking.

Objectives

This study investigated the prevalence of TMD pain and somatic symptoms in migraine patients, examining their relationships with pain characteristics, psychological distress, and quality of life (QOL). Additionally, it identified factors associated with moderate-to-severe distress, low QOL, and poor general health.

Methods

Participants were recruited from a neurology clinic, where migraines were diagnosed based on the ICHD-3 criteria. A trained interviewer administered a questionnaire comprising sociodemographics, migraine-specific information, the DC/TMD TMD pain screener (TPS), Graded Chronic Pain Scale (GCPS), Patient Health Questionnaires (PHQ-15/PHQ-4), and WHOQOL-BREF. Data were analysed employing Chi-square/Mann–Whitney U tests, Spearman's correlation, and logistic regression analysis (α = 0.05).

Results

Among the 106 participants (mean age 45.3 years [SD = 14.0]), 31.1% experienced TMD pain, while 37.7% exhibited medium-to-high somatic symptoms. Individuals with comorbid migraine-TMD pain had a higher somatic symptom burden, distress, and poorer psychological/environmental QOL. Those with medium-to-high somatic symptoms reported more frequent migraines, greater pain intensity/disability, higher TMD pain propensity, elevated distress, and worse QOL in all domains. Somatic symptoms, but not TMD pain, were negatively and moderately correlated with general health, physical, and psychological QOL (rs = −0.41 to −0.53). Somatic symptoms (OR 1.34) and poor general health (OR 3.06) increased the odds of moderate-to-severe distress and low overall QOL, respectively.

Conclusions

To effectively manage migraine patients, screening for TMDs and addressing somatic symptoms and general health are essential for reducing psychological distress and enhancing overall QOL.

背景：目前对东南亚偏头痛患者疼痛性颞下颌紊乱（TMDs）和躯体症状的研究尚缺乏。目的：本研究调查偏头痛患者TMD疼痛和躯体症状的患病率，探讨其与疼痛特征、心理困扰和生活质量（QOL）的关系。此外，它还确定了与中度至重度痛苦、低生活质量和一般健康状况不佳相关的因素。方法：参与者从神经病学诊所招募，根据ICHD-3标准诊断偏头痛。一名训练有素的采访者对患者进行问卷调查，包括社会人口统计学、偏头痛特异性信息、DC/TMD TMD疼痛筛查（TPS）、慢性疼痛分级量表（GCPS）、患者健康问卷（PHQ-15/PHQ-4）和WHOQOL-BREF。资料分析采用χ 2 /Mann-Whitney U检验、Spearman相关和logistic回归分析（α = 0.05）。结果：106名参与者（平均年龄45.3岁[SD = 14.0]）中，31.1%经历过TMD疼痛，37.7%表现出中重度躯体症状。患有偏头痛- tmd合并症的个体有较高的躯体症状负担、窘迫和较差的心理/环境生活质量。有中重度躯体症状的患者报告偏头痛更频繁，疼痛强度/残疾更大，TMD疼痛倾向更高，痛苦加剧，所有领域的生活质量更差。躯体症状，而不是TMD疼痛，与总体健康、身体和心理生活质量呈负相关和中度相关（rs = -0.41至-0.53）。躯体症状（OR 1.34）和一般健康状况不佳（OR 3.06）分别增加了中度至重度痛苦和低总体生活质量的几率。结论：为了有效管理偏头痛患者，筛查tmd，解决躯体症状和一般健康问题对于减少心理困扰和提高总体生活质量至关重要。

Background

While maximum isometric pressure (MIP) is widely used in clinical and research settings, reduced lingual swallow pressure (LSP) has been observed in patients with dysphagia and in older healthy adults. However, limited evidence exists on the test–retest reliability of LSP across different bolus consistencies.

Objective

This study assessed the test–retest reliability of LSP measurements in both younger and older adults with healthy swallowing function to identify factors influencing oral swallowing pressure.

Methods

Participants 18–40 years (younger) and 60+ years (older) were assessed across four separate sessions. Bolus types included trials of saliva, thin, mildly thick and extremely thick water, randomised across study visits. Two-way mixed effects models with absolute agreement were used to calculate intraclass correlation coefficients (ICCs) and evaluate test–retest reliability of LSP for each swallow type (regular or effortful) and bolus type. Linear mixed effects regression modelling was used to examine the factors influencing LSP.

Results

A total of 51 participants were included. Test–retest reliability for LSP ranged from good to excellent across both groups (ICC = 0.79–0.98). Reliability was non-significantly higher in the older group (ICC = 0.96) and during effortful swallows (ICC = 0.94). Effort level significantly influenced LSP estimates, with effortful swallows producing about 1.83 times more lingual pressure than regular swallows. There were no significant effects of age, sex, or bolus type on LSP.

Conclusion

These findings suggest that LSP measurements are reliable across measurement time points in nondysphagic participants, regardless of age, effort level, or bolus type. Only swallow effort level significantly influenced LSP estimates.

背景：虽然最大等长压力（MIP）在临床和研究中被广泛使用，但在吞咽困难患者和健康老年人中也观察到舌吞压力（LSP）的降低。然而，LSP跨不同一致性的重测信度研究证据有限。目的：本研究对吞咽功能正常的年轻人和老年人进行LSP测量的重测信度评估，以确定影响口腔吞咽压力的因素。方法：对18-40岁（年轻）和60岁以上（年长）的参与者进行四个单独的评估。药丸类型包括唾液试验、稀水、轻度浓水和极浓水，在研究访问中随机分配。采用绝对一致的双向混合效应模型计算类内相关系数（ICCs），并评估LSP对每一种吞咽类型（常规或费力）和丸剂类型的重测信度。采用线性混合效应回归模型研究影响LSP的因素。结果：共纳入51例受试者。两组LSP的重测信度从良好到优秀不等（ICC = 0.79-0.98）。可靠性在老年组（ICC = 0.96）和努力吞咽组（ICC = 0.94）中无显著性提高。努力程度显著影响LSP估计，努力吞咽产生的舌压是正常吞咽产生舌压的1.83倍。年龄、性别、药物类型对LSP无显著影响。结论：这些发现表明LSP测量在非吞咽困难参与者的测量时间点上是可靠的，无论年龄，努力水平或丸类型。只有吞咽努力程度显著影响LSP估计。

Journal of oral rehabilitation

Pub Date : 2025-11-28 DOI: 10.1111/joor.70121

Background

Chronic orofacial pain is a prevalent health issue with multifactorial aetiology, including potential contributions from diet-related inflammation. This study aimed to investigate the association between dietary inflammatory potential, assessed using the Dietary Inflammatory Index (DII), and self-reported oral pain among US adults.

Methods

We conducted a cross-sectional analysis using data from 23 802 participants in the National Health and Nutrition Examination Survey (NHANES) 2005–2018 who completed dietary recalls and responded to oral health questions. Oral pain was assessed by the frequency of self-reported aching in the mouth over the past year (NHANES variable OHQ620). Logistic regression models were used to assess the association between DII scores and oral pain. Subgroup analyses were conducted to identify populations most affected by a pro-inflammatory diet.

Results

Higher DII scores were significantly associated with an increased likelihood of experiencing oral pain. Participants in the highest DII quintile (27.19%) had a 19% higher risk of oral pain compared with those in the lowest quintile (20.69%), even after full adjustment (OR = 1.19, 95% CI: 1.03–1.37, p = 0.016). The association was particularly pronounced in younger individuals, females, non-Hispanic Whites, those with higher socio-economic status, normal BMI, a history of smoking, and relatively low alcohol consumption.

Conclusion

These findings suggest that pro-inflammatory dietary patterns may exacerbate oral pain, potentially mediated through systemic inflammation or local mucosal irritation. While based on self-reported oral pain, the study highlights diet modification as a preventive strategy and calls for further research on specific pain subtypes.

背景：慢性口面部疼痛是一种多因素的普遍健康问题，包括与饮食相关的炎症的潜在贡献。本研究旨在调查饮食炎症潜能（通过饮食炎症指数（DII）评估）与美国成年人自我报告的口腔疼痛之间的关系。方法：我们对2005-2018年国家健康与营养检查调查（NHANES）中23802名参与者的数据进行了横断面分析，这些参与者完成了饮食召回并回答了口腔健康问题。口腔疼痛通过过去一年中自我报告口腔疼痛的频率来评估（NHANES变量OHQ620）。采用Logistic回归模型评估DII评分与口腔疼痛之间的关系。进行亚组分析以确定受促炎饮食影响最大的人群。结果：较高的DII评分与经历口腔疼痛的可能性增加显著相关。即使在完全调整后，DII最高五分位数的参与者（27.19%）与最低五分位数的参与者（20.69%）相比，口腔疼痛的风险高出19% （OR = 1.19, 95% CI: 1.03-1.37, p = 0.016）。这种关联在年轻人、女性、非西班牙裔白人、社会经济地位较高、BMI正常、有吸烟史和相对较低饮酒量的人群中尤为明显。结论：这些研究结果表明，促炎饮食模式可能会加剧口腔疼痛，可能通过全身炎症或局部粘膜刺激介导。虽然基于自我报告的口腔疼痛，但该研究强调了饮食调整作为一种预防策略，并呼吁对特定疼痛亚型进行进一步研究。

Background

Joint hypermobility (JH), particularly at the temporomandibular joint (TMJ), has been proposed as a potential risk factor for temporomandibular disorders (TMD). However, its heterogeneous diagnostic approaches (clinical, anamnestic and imaging) limit the identification of reliable predictors of masticatory dysfunction and TMD outcomes.

Objectives

To determine which diagnostic methods for TMJ hypermobility best predict masticatory dysfunction and the clinical and functional repercussions of TMD.

Methods

This cross-sectional study included 126 adults recruited at the Bauru School of Dentistry. Participants were classified by Diagnostic Criteria for TMD (DC/TMD) into painful, dysfunction or combined groups, balanced by history of open-locking. Assessments comprised DC/TMD and ICOP examinations, symptom intensity on the visual analog scale (VAS), Beighton score, pressure pain thresholds, bite-force and fatigue tests, ultrasound of the TMJ capsule and masseter, CBCT-based condylar angle and validated measures of mandibular function and psychosocial factors.

Results

Bivariate analyses yielded associations, but multivariate models identified specific predictors. Open-locking independently predicted TMJ subluxation and higher joint instability. Increased condylar angle was associated with greater assisted opening and midline deviation. Unassisted opening predicted a larger condylar angle, greater pain-free opening and lateral condylar jump; assisted opening similarly predicted pain-free opening and lateral condylar jump. Lateral condylar jump independently predicted functional limitation in wide-opening tasks.

Conclusion

Clinical, functional and imaging indicators of TMJ hypermobility capture distinct aspects of the condition. While open-locking, condylar angle and mouth-opening measures predict specific features, no single marker explains the full spectrum and TMJ hypermobility shows limited impact on overall TMD outcomes.

背景：关节活动过度（JH），特别是在颞下颌关节（TMJ），已被认为是颞下颌疾病（TMD）的潜在危险因素。然而，其不同的诊断方法（临床、记忆和影像学）限制了对咀嚼功能障碍和TMD结果的可靠预测。目的：探讨颞下颌关节运动亢进的诊断方法，以更好地预测咀嚼功能障碍及其临床和功能影响。方法：这项横断面研究包括从Bauru牙科学院招募的126名成年人。根据TMD诊断标准（DC/TMD）将参与者分为疼痛组、功能障碍组或合并组，并根据开锁病史进行平衡。评估包括DC/TMD和ICOP检查、视觉模拟量表（VAS）的症状强度、Beighton评分、压痛阈值、咬力和疲劳测试、TMJ囊和咬肌的超声检查、基于cbct的髁角以及下颌功能和社会心理因素的有效测量。结果：双变量分析得出了相关性，但多变量模型确定了特定的预测因子。开锁独立预测TMJ半脱位和更高的关节不稳定性。增加的髁角与更大的辅助开口和中线偏差有关。无辅助开放预示着更大的髁角，更大的无痛开放和外侧髁跳跃；辅助开放同样预测无痛开放和外侧髁跳。外侧髁跳独立预测大开口任务的功能限制。结论：颞下颌关节过动症的临床、功能和影像学指标反映了该疾病的不同方面。虽然开锁、髁突角度和开口测量可以预测特定的特征，但没有单一的标记可以解释全谱，TMJ过度活动对整体TMD结果的影响有限。

Background

Obesity is associated with periodontal disease, which compromises chewing by reducing masticatory efficiency. However, little is known about periodontal health and the use of removable prostheses in obese older adults.

Objective

To evaluate the effects of removable partial denture (RPD) insertion on periodontal condition, maximum bite force (MBF), and oral health-related quality of life (OHRQoL) in obese and normal-weight older adults.

Material and Methods

Edentulous older adults in the maxilla and partially edentulous in the mandible were assigned to obese (71.9 ± 5.0 years; n = 12, 6 women and 6 men) and normal-weight (69.9 ± 6.7 years; n = 6 women and 6 men) groups. Periodontal parameters (probing depth, clinical attachment loss, gingival recession, bleeding on probing) were measured with William's probe, and plaque was assessed with the modified O'Leary index. MBF was recorded with pressure sensors, and OHRQoL was evaluated with the OHIP-14. Periodontal parameters and MBF were measured before and 3, 6, 9, and 12 months after RPD insertion, while OHRQoL was measured before, and after 6 and 12 months. Data were analysed by repeated-measures ANOVA with Bonferroni post hoc tests (α = 0.05).

Results

Obese individuals showed higher bleeding on probing (p = 0.02) and greater MBF (p = 0.002) at all time points. MBF increased in both groups after 3 months, while OHRQoL remained lower in obese individuals (p = 0.01). Both groups showed significant plaque reduction after RPD insertion (p < 0.05).

Conclusion

Obese older adults wearing RPDs exhibit greater periodontal impairment and poorer OHRQoL, despite similar improvements in MBF and plaque reduction. These findings underscore the need for closer periodontal monitoring and targeted oral health strategies for obese older adults receiving RPDs.

Trial Registration

背景：肥胖与牙周病有关，牙周病通过降低咀嚼效率影响咀嚼。然而，对于肥胖老年人的牙周健康和可移动假体的使用知之甚少。目的：评价可摘局部义齿（RPD）对肥胖和正常体重老年人牙周状况、最大咬合力（MBF）和口腔健康相关生活质量（OHRQoL）的影响。材料与方法：将上颌无牙老年人和下颌骨部分无牙老年人分为肥胖组（71.9±5.0岁，女6人，男6人，n = 12）和正常体重组（69.9±6.7岁，女6人，男6人）。用威廉氏探针测量牙周参数（探诊深度、临床附着丧失、牙龈退缩、探诊出血），用改良的O'Leary指数评估牙菌斑。用压力传感器记录MBF，用OHIP-14评价OHRQoL。分别于RPD置入前、置入后3、6、9、12个月测定牙周参数和MBF，于置入后6、12个月测定OHRQoL。资料采用Bonferroni事后检验的重复测量方差分析（α = 0.05）。结果：肥胖个体在所有时间点均表现出较高的探查出血（p = 0.02）和较高的MBF （p = 0.002）。3个月后，两组MBF均增加，而肥胖个体的OHRQoL仍较低（p = 0.01）。结论：佩戴RPD的肥胖老年人牙周损伤更严重，OHRQoL更差，尽管MBF和菌斑减少的改善相似。这些发现强调了对接受RPDs的肥胖老年人进行更密切的牙周监测和有针对性的口腔健康策略的必要性。试验注册：巴西临床试验注册：ReBEC #U1111-1228-7273。

Periodontal parameters (probing depth, clinical attachment loss, gingival recession, bleeding on probing) were measured with William's probe, and plaque was assessed with the modified O'Leary index. MBF was recorded with pressure sensors, and OHRQoL was evaluated with the OHIP-14. Periodontal parameters and MBF were measured before and 3, 6, 9, and 12 months after RPD insertion, while OHRQoL was measured before, and after 6 and 12 months.
