Objectives

This study assessed the effects of 15% and 20% carbamide peroxide (CP) on color, surface roughness, and hardness of computer-aided design/computer-aided manufacturing (CAD/CAM) dental ceramics.

Materials and Methods

This in vitro study was conducted on 120 Vita Mark II, Celtra Duo, and Suprinity CAD/CAM ceramic specimens. The ceramic specimens in each group (n = 40) were randomly assigned to two subgroups (n = 20) for polishing and glazing, and their baseline color, surface roughness (Ra), and hardness were assessed. In each subgroup, half of the specimens were exposed to 15% CP, while the other half were exposed to 20% CP. Their color change (ΔE), surface roughness, and hardness were then measured again. Surface roughness, hardness, and color were analyzed sequentially by profilometer, Vickers hardness tester, and spectrophotometer, respectively. Data were analyzed by repeated measures ANOVA, one-way ANOVA, and post hoc Bonferroni test (α = 0.05).

Results

The surface roughness of all groups significantly increased after bleaching treatment (p < 0.05). Surface hardness of all groups decreased after bleaching treatment, but this reduction was only significant in Vita Mark II subgroups (glazed, polished, 15%, and 20% CP). The ΔE was not clinically and visually perceivable in any group.

Conclusion

The present results revealed that concentration of CP and type of surface treatment affected the surface properties of CAD/CAM ceramics. Type of surface treatment only affected the surface hardness of Vita Mark II ceramics (p < 0.05). Concentration of CP had a significant effect only on polished Vita Mark II.

Objectives

With Artificial Intelligence (AI) profoundly affecting education, ensuring that students in health disciplines are ready to embrace AI is essential for their future workforce integration. This study aims to explore dental students' readiness to use AI, perceptions about AI in health education and healthcare, and their AI-related educational needs.

Material and Methods

A cross-sectional survey was conducted among dental students at the College of Dental Medicine, Qatar University. The survey assessed readiness for AI using the Medical Artificial Intelligence Readiness Scale (MAIRS). Students' perceptions of AI in healthcare and health education and their educational needs were also explored.

Results

A total of 94 students responded to the survey. AI readiness scores were average (3.3 ± 0.64 out of 5); while participants appeared more ready for the vision and ethics domains of MAIRS, they showed less readiness regarding cognition and ability. Participants scored average on AI perceptions (3.35 ± 0.45 out of 5), with concerns regarding AI risks and disadvantages. They expressed a high need for knowledge and skills related to AI use in healthcare (84%), AI for health-related research (81.9%), and AI in radiology and imaging procedures (79.8%). Student readiness had a significant correlation with AI perceptions and perceived level of AI knowledge.

Conclusions

This is the first study in Qatar exploring dental students' AI readiness, perceptions, and educational needs regarding AI applications in education and healthcare. The perceived AI knowledge gaps could inform future curricular AI integration. Advancing AI skills and deepening AI comprehension can empower future dental professionals through anticipated advances in the AI-driven healthcare landscape.

目标:随着人工智能(AI)对教育产生深远影响,确保卫生学科的学生做好接受人工智能的准备对于他们未来的劳动力整合至关重要。本研究旨在探讨牙科学生使用人工智能的准备情况、对健康教育和医疗保健领域人工智能的看法以及他们与人工智能相关的教育需求:对卡塔尔大学牙医学院的牙科学生进行了一项横向调查。调查使用医学人工智能准备程度量表(MAIRS)评估了人工智能的准备程度。此外,还探讨了学生对医疗保健和健康教育中的人工智能的看法以及他们的教育需求:共有 94 名学生回答了调查。人工智能准备度得分一般(3.3 ± 0.64,满分 5 分);虽然参与者在 MAIRS 的愿景和伦理领域的准备度较高,但在认知和能力方面的准备度较低。参与者在人工智能认知方面的得分一般(3.35 ± 0.45,满分 5 分),对人工智能的风险和弊端表示担忧。他们表示非常需要与人工智能在医疗保健中的应用(84%)、人工智能在健康相关研究中的应用(81.9%)以及人工智能在放射学和成像程序中的应用(79.8%)相关的知识和技能。学生的准备程度与对人工智能的看法和人工智能知识的认知水平有明显的相关性:这是卡塔尔首次就人工智能在教育和医疗保健领域的应用,对牙科学生的人工智能准备程度、认知和教育需求进行研究。认知到的人工智能知识差距可以为未来的人工智能课程整合提供参考。提高人工智能技能和加深对人工智能的理解,可以使未来的牙科专业人员在人工智能驱动的医疗保健领域取得预期进展。

Objectives

To evaluate the validity of the Golden Proportion, Golden Percentage, and Recurring Esthetic Dental (RED) Proportion among Kenyans of African descent with naturally well-aligned teeth.

Materials and Methods

Standardized frontal photographic images of the smiles of 175 participants aged 18–35 years were obtained, and Adobe Photoshop was used to analyze and measure the frontal widths of the maxillary central and lateral incisors and canines in triplicate. The average teeth widths were calculated to determine the existence of the Golden Proportion, Golden Percentage, and RED Proportion, and their validity using independent sample t-tests to compare the differences in the mean teeth widths at α < 0.05.

Results

The number of male and female participants was 107 (61.1%) and 68 (38.9%), respectively. The Golden Proportion between the maxillary central and lateral incisors was found in 4.0% on the right and 2.8% on the left of all the participants, but between the maxillary lateral incisors and canines was found in only 0.6% on the right of male participants (p < 0.0001). The RED Proportion between the maxillary lateral and central incisors was in the range of 67%–70%, and between the canines and lateral incisors was 82%–84% (p < 0.0001). The proportion of RED was not constant, and gradually increased distally. The Golden Percentage of 15% was observed in the lateral incisors bilaterally; however, in the central incisors and the canines, the Golden Percentage was 22% and 12%, respectively.

Conclusion

The Golden and RED Proportions were invalid determinants of anterior teeth proportions. The Golden Percentage existed only in the lateral incisors. The Golden Proportion, RED Proportion, and Golden Percentage theories may not be applicable to all populations when designing smiles. Racial and ethnic backgrounds are important considerations to establish objective quantifiable values of anterior tooth proportions that are beneficial for esthetic restorations.

目的在牙齿自然整齐的非洲裔肯尼亚人中评估黄金比例、黄金百分比和复发性牙齿美容比例(RED)的有效性:获取 175 名 18-35 岁参与者微笑时的标准化正面照片,并使用 Adobe Photoshop 分析和测量上颌中切牙、侧切牙和犬齿的正面宽度,一式三份。计算平均牙齿宽度,以确定是否存在黄金比例、黄金比例和 RED 比例,并使用独立样本 t 检验比较平均牙齿宽度在 α 处的差异,以确定其有效性:男性和女性参与者人数分别为 107 人(61.1%)和 68 人(38.9%)。在所有参与者中,上颌中切牙和侧切牙之间的黄金比例在右侧为 4.0%,在左侧为 2.8%,但在男性参与者中,上颌侧切牙和犬齿之间的黄金比例在右侧仅为 0.6%(p 结论:在所有参与者中,上颌中切牙和侧切牙之间的黄金比例在右侧为 4.0%,在左侧为 2.8%:黄金比例和红比例是决定前牙比例的无效因素。黄金比例只存在于侧切牙中。在设计微笑时,黄金比例、RED 比例和黄金比例理论可能不适用于所有人群。种族和民族背景是确定前牙比例的客观量化值的重要考虑因素,有利于美学修复。

Objectives

The human oral microbiome, a complex ecosystem linked to oral and systemic health, harbors a diverse array of microbial populations, including antimicrobial resistance genes (ARGs). As a critical component of the One Health approach to tackle antibiotic resistance, comprehending the oral resistome's composition and diversity is imperative. The objective of this study was to investigate the impact of chemical cell lysis treatment using MetaPolyzyme on the detectability of the oral microbiome, resistome, and DNA quality and quantity.

Materials and Methods

Saliva samples were collected from five healthy individuals, and each of the samples was subjected to DNA extraction with and without the treatment with MetaPolyzyme. Through metagenomic sequencing, we analyzed, assessed, and compared the microbial composition, resistome, and DNA characteristics between both groups of extracted DNA.

Results

Our study revealed that MetaPolyzyme treatment led to significant shifts in the detectability of microbial composition, favoring Gram-positive bacteria, notably Streptococcus, over Gram-negative counterparts. Moreover, the MetaPolyzyme treatment also resulted in a distinct change in ARG distribution. This shift was characterized by an elevated proportion of ARGs linked to fluoroquinolones and efflux pumps, coupled with a reduction in the prevalence of tetracycline and β-lactam resistance genes when compared with the nontreated group. Alpha diversity analysis demonstrated altered species and ARG distribution without affecting overall diversity, while beta diversity analysis confirmed significant differences in the taxonomical composition and oral resistome between treated and nontreated groups.

Conclusions

These findings underscore the critical role of cell lysis treatment in optimizing oral metagenomic studies and enhance our understanding of the oral resistome's dynamics in the context of antimicrobial resistance.

目的:人类口腔微生物组是一个复杂的生态系统,与口腔和全身健康息息相关,其中蕴藏着各种各样的微生物种群,包括抗菌药耐药性基因 (ARGs)。作为应对抗生素耐药性的 "一体健康 "方法的重要组成部分,了解口腔耐药基因组的组成和多样性势在必行。本研究的目的是调查使用 MetaPolyzyme 进行化学细胞裂解处理对口腔微生物组、耐药性组以及 DNA 质量和数量的影响:从五名健康人口中采集唾液样本,对每个样本进行DNA提取,并分别使用MetaPolyzyme处理和不使用MetaPolyzyme处理。通过元基因组测序,我们分析、评估和比较了两组提取DNA的微生物组成、抗性组和DNA特征:结果:我们的研究发现,MetaPolyzyme 处理导致微生物组成的可检测性发生了显著变化,革兰氏阳性菌(尤其是链球菌)比革兰氏阴性菌更受青睐。此外,MetaPolyzyme 处理还导致 ARG 分布发生明显变化。与未处理组相比,这种变化的特点是与氟喹诺酮类药物和外排泵相关的ARG比例上升,同时四环素和β-内酰胺耐药基因的流行率下降。阿尔法多样性分析表明,物种和 ARG 分布发生了改变,但不影响总体多样性,而贝塔多样性分析则证实,治疗组和非治疗组之间的分类组成和口腔耐药性组存在显著差异:这些发现强调了细胞裂解处理在优化口腔元基因组研究中的关键作用,并加深了我们对抗菌药耐药性背景下口腔耐药性组动态的了解。

Background

Myofascial pain syndrome (MPS) is a particular type of temporomandibular joint disorder. Research findings comparing various treatment approaches are scarce and controversial. Therefore, this study aimed to compare the effectiveness of ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises in reducing pain intensity and improving mandibular mobility in patients with MPS.

Methods

It was a single-blind, randomized, parallel-group, active-controlled trial that took place between April 2023 and October 2023 at the Department of Fixed Prosthodontics, Damascus University. Patients older than 18 years old with myofascial pain accompanied by limited jaw opening and pain lasting for at least 6 months were included. Eighty patients were randomly assigned into four groups using online randomization software: ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises. Only outcome assessors were masked to treatment allocation. The exercise regimen was the exercise program for patients with TMD. The following primary outcome measures were considered at the baseline (t0), at the first (t1), second (t2), and fourth (t3) week of treatment, and at the second (t4) and fifth (t5) month of follow-up: pain intensity using the visual analogue scale, maximum interincisal opening, right lateral movement, and left lateral movement measured in millimeters.

Results

The pain level changed from severe to mild at t3 in ultrasound therapy, stabilization splint, and TheraBite device groups. In the masticatory muscle exercises group, it changed to moderate, with a significant difference between ultrasound therapy (p = 0.012) and stabilization splint (p = 0.013) groups. In addition, the mandibular mobility continued to improve at the subsequent follow-up periods (t4 and t5).

Conclusions

All therapies are equally effective after 5-month follow-up. However, ultrasound therapy and stabilization splints have the benefit of achieving rapid improvement.

Objectives

Special needs dentistry (SND) is a vast and fragmented field of study. This comprehensive bibliometric analysis aimed to evaluate the scope of SND, including the existing knowledge base, distribution structure, quantitative relationships, and research trends.

Material and Methods

A systematic search was conducted on March 10, 2022, using the Web of Science Core Collection database, covering the period from 1985 to 2021, focusing on studies reporting on special needs populations in a dentally relevant context. Records were title-screened and analyzed for key bibliometric indicators.

Results

Among 48,374 articles, 13,869 underwent bibliometric analysis. Peak SND research occurred during 1985–1997. United States led in productivity, trailed by Brazil and Japan. University of Sao Paulo excelled in Brazil, University of Washington and University of North Carolina in the United States. The Journal of Dental Research was the most productive source of research and also had the highest number of citations, followed by Community Dentistry and Oral Epidemiology. Keyword analysis revealed that “elderly”, “caries”, and “epidemiology” were the most commonly used author keywords.

Conclusions

This study represents the first bibliometric analysis of SND literature. It emphasizes the need for increased collaboration between institutions and authors. Furthermore, it suggests focusing on research input from non-dental disciplines and populations with rarer intellectual or developmental conditions.

目标:特需牙科(SND)是一个庞大而分散的研究领域。这项综合性文献计量分析旨在评估特需牙科的范围,包括现有的知识基础、分布结构、数量关系和研究趋势:2022 年 3 月 10 日,我们使用 Web of Science Core Collection 数据库对 1985 年至 2021 年期间的文献进行了系统检索,重点检索了在牙科相关背景下报告特殊需求人群的研究。对记录进行了标题筛选,并对关键文献计量指标进行了分析:在 48,374 篇文章中,有 13,869 篇进行了文献计量分析。1985-1997 年是 SND 研究的高峰期。美国的生产力居首位,巴西和日本紧随其后。巴西的圣保罗大学、美国的华盛顿大学和北卡罗来纳大学表现突出。牙科研究杂志》是研究成果最多的来源,也是被引用次数最多的来源,其次是《社区牙科》和《口腔流行病学》。关键词分析显示,"老年人"、"龋齿 "和 "流行病学 "是作者最常用的关键词:本研究首次对 SND 文献进行了文献计量分析。结论:本研究是首次对 SND 文献进行文献计量分析,强调了加强机构与作者之间合作的必要性。此外,它还建议关注非牙科学科和智力或发育状况较差人群的研究投入。

Objective

This study aimed to assess undergraduate dental students' communication skills in relation to patient sociodemographic factors using a three-perspective approach; the student, the patient, and the clinical instructor perspective.

Materials and Methods

A cross-sectional study was conducted using validated modified-communication tools; Patient Communication Assessment Instruments (PCAI), Student Communication Assessment Instruments (SCAI), and Clinical Communication Assessment Instruments (CCAI). Moreover, 176 undergraduate clinical year students were recruited in this study whereby each student was assessed by a clinical instructor, a patient, and self-evaluation.

Results

The clinical communication skills domains were not significantly influenced by patient sociodemographic factors, including sex, educational background, and the number of visits (p > .05). However, this study revealed a statistically significant difference in the domain of “caring and respectful” of the SCAI between the low- and middle-income groups.

Conclusions

Overall, most of the patient sociodemographic factors did not affect clinical communication skills. However, patient income groups played a significant role in one of the communication domains.

目的:本研究旨在采用三视角方法(学生视角、患者视角和临床指导教师视角)评估牙科本科生的沟通技巧与患者社会人口学因素的关系:本研究旨在采用三视角方法(学生视角、患者视角和临床教师视角)评估牙科本科生的沟通技巧与患者社会人口学因素的关系:使用经过验证的改良沟通工具:患者沟通评估工具(PCAI)、学生沟通评估工具(SCAI)和临床沟通评估工具(CCAI)进行了一项横断面研究。此外,本研究还招募了 176 名本科临床年级学生,每位学生都接受了临床教师、患者和自我评价的评估:结果:临床沟通技能领域受患者社会人口学因素(包括性别、教育背景和就诊次数)的影响不大(P > .05)。然而,本研究显示,在 SCAI 的 "关怀和尊重 "领域,低收入群体和中等收入群体之间的差异具有统计学意义:总体而言,大多数患者的社会人口学因素并不影响临床沟通技巧。结论:总体而言,大多数患者的社会人口学因素并不影响临床沟通技巧,但患者的收入群体在其中一个沟通领域中起着重要作用。

Objective

To assess the reliability of implant stability measurements recorded with the Periotest device and to investigate the differences in values when these measurements were taken on implant retained crowns and healing abutments.

Materials and Methods

Fifty-six implants in eight synthetic bone blocks were used to carry out implant stability measurements using the Periotest device by two different operators. Each block constituted an example of bone of density D1, D2, D3, or D4, and two blocks of each density were used. The healing abutments placed were of a height to allow approximately 6 mm of the implant-abutment complex to be supracrestal and temporary crowns were made to match the dimensions of an average central incisor. Descriptive statistics were used to describe the perio test values (PTVs) at each of the different heights on the implant abutments and implant crowns. Means for each site were calculated and distribution of data assessed using the Kruskal Wallis test. The interclass correlation coefficient (ICC) was used to determine the relationship between the PTVs recorded on the implant abutments and implant crowns.

Results

The mean PTV (±standard devidation) recorded across all sites was 5.57 ± 11.643 on the implant abutments, and 12.27 ± 11.735 on the temporary crowns. Excellent/good inter-operator ICCs were recorded for the mid-abutment site in all bone blocks D1–D4 (ICC = 0.814, p < 0.001, ICC = 0.922, p < 0.001, ICC = 0.938, p < 0.001, ICC = 776, p < 0.001). For mid crown sites, ICC between operators was excellent/good only for recordings in D2 bone (ICC = 0.897, p < 0.001).

Conclusions

Periotest device seems to be able to reliably measure implant stability across all types of bones when the implant stability is assessed at approximately 3 mm coronal to the implant platform for abutments and 4.5 mm for implant supported single crowns.

目的评估使用 Periotest 设备记录的种植体稳定性测量值的可靠性,并研究这些测量值在种植体固位冠和愈合基台上的差异:两个不同的操作者使用 Periotest 设备对八个合成骨块中的 56 个种植体进行了种植体稳定性测量。每个骨块的密度分别为 D1、D2、D3 或 D4,每个密度使用两个骨块。植入的愈合基台的高度为种植体-基台复合体约 6 毫米,临时牙冠的尺寸与普通中切牙一致。使用描述性统计来描述种植基台和种植体冠不同高度处的周缘测试值(PTV)。使用 Kruskal Wallis 检验法计算每个部位的平均值并评估数据的分布情况。类间相关系数(ICC)用于确定种植体基台和种植体冠上记录的 PTV 之间的关系:所有部位记录的平均 PTV(±标准偏差)为:种植基台 5.57 ± 11.643,临时牙冠 12.27 ± 11.735。在所有骨块 D1-D4 中的基台中间部位,记录到了极好/良好的操作者间 ICC(ICC = 0.814,p 结论:Periotest 设备似乎能够准确地测量种植体的位置:如果在基台与种植体平台之间约 3 毫米的冠状面上评估种植体的稳定性,在种植体支持的单冠上评估 4.5 毫米的冠状面上评估种植体的稳定性,那么 Periotest 设备似乎能够可靠地测量所有类型骨骼的种植体稳定性。

Objectives

Self-performed oral hygiene is essential for preventing dental caries, periodontal, and peri-implant diseases. Oral irrigators are adjunctive oral home care aids that may benefit oral health. However, the effects of oral irrigation on oral health, its role in oral home care, and its mechanism of action are not fully understood. A comprehensive search of the literature revealed no existing broad scoping reviews on oral irrigators. Therefore, this study aimed to provide a comprehensive systematic review of the literature on oral irrigation devices and identify evidence gaps.

Methods

The Joanna Briggs Institute and Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines were utilized to prepare the review. Four databases and eight gray literature sources were searched for English publications across any geographical location or setting.

Results

Two hundred and seventy-five sources were included, predominantly from scientific journals and academic settings. Most studies originated from North America. Research primarily involved adults, with limited studies in children and adolescents. Oral irrigation was safe and well-accepted when used appropriately. It reduced periodontal inflammation, potentially by modulating the oral microbiota, but further research needs to clarify its mechanism of action. Promising results were reported in populations with dental implants and special needs. Patient acceptance appeared high, but standardized patient-reported outcome measures were rarely used. Anti-inflammatory benefits occurred consistently across populations and irrigant solutions. Plaque reduction findings were mixed, potentially reflecting differences in study designs and devices.

Conclusions

Oral irrigators reduce periodontal inflammation, but their impact on plaque removal remains unclear. Well-designed, sufficiently powered trials of appropriate duration need to assess the clinical, microbiological, and inflammatory responses of the periodontium to oral irrigation, particularly those with periodontitis, dental implants, and special needs. Patient-reported outcome measures, costs, caries prevention, and environmental impact of oral irrigation need to be compared to other oral hygiene aids.

目的:自我进行口腔卫生对于预防龋齿、牙周病和种植体周围疾病至关重要。口腔冲洗器是口腔家庭护理的辅助工具,可能有益于口腔健康。然而,口腔冲洗对口腔健康的影响、其在口腔家庭护理中的作用及其作用机制尚未完全清楚。在对文献进行全面检索后发现,目前还没有关于口腔冲洗器的广泛范围综述。因此,本研究旨在对有关口腔冲洗器的文献进行全面系统的综述,并找出证据差距:本综述采用了乔安娜-布里格斯研究所(Joanna Briggs Institute)和《系统综述和元分析首选报告项目》(Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews)指南。在四个数据库和八个灰色文献来源中搜索了任何地理位置或环境下的英文出版物:结果:共收录了 275 篇文献,主要来自科学期刊和学术机构。大多数研究来自北美。研究主要涉及成年人,对儿童和青少年的研究有限。如果使用得当,口腔冲洗是安全的,也是被广泛接受的。它可能通过调节口腔微生物群来减少牙周炎症,但还需要进一步的研究来明确其作用机制。据报道,在种植牙和有特殊需求的人群中取得了可喜的成果。患者的接受度似乎很高,但很少使用标准化的患者报告结果测量方法。不同人群和不同的冲洗液都能产生一致的消炎效果。减少牙菌斑的结果不一,可能反映了研究设计和设备的差异:结论:口腔冲洗器能减轻牙周炎症,但对去除牙菌斑的影响仍不明确。需要对口腔冲洗对牙周的临床、微生物和炎症反应进行评估,尤其是那些患有牙周炎、种植牙和有特殊需求的患者。需要将患者报告的结果测量、成本、龋齿预防以及口腔冲洗对环境的影响与其他口腔卫生辅助工具进行比较。

Objective

The present systematic review explored the involvement of enzymatic and nonenzymatic antioxidants in periodontitis, drawing from established literature.

Materials and Methods

The research approach encompassed an extensive electronic search from 2000 to 2023 across databases such as PubMed, Science Direct, and Wiley Online Library and cross-referencing using specific keywords.

Results

The initial literature exploration generated a total of 766 articles. After thoroughly examining the abstracts, 693 articles were excluded from consideration due to duplication and lack of relevance to the central research inquiry. Following that, 73 articles were left for in-depth evaluation. Following a qualitative assessment, 35 studies that satisfied the inclusion criteria were chosen, while 38 were removed for not meeting the necessary standards. Within this selection, a meta-analysis was conducted on 11 articles that provided consistent data for quantitative synthesis. Specifically, the analysis of glutathione (GSH) levels in serum samples revealed a standardized mean difference (SMD) of −5.552 µg/mL (CI 95%: −9.078 to −2.026; P-0.002). In contrast, the analysis of glutathione peroxidase (GPx) enzymes in gingival crevicular fluid (GCF) samples displayed an overall SMD of 2.918 ng/µL (CI 95%: 0.372–5.465; P-0.025), while salivary samples exhibited an overall SMD value of 0.709 U/l (95% CI: −1.907–3.325; P-0.596) which is of insignificant.

Conclusion

The systematic review findings suggest a notable decrease in antioxidant enzymes across various systemic biological samples among patients with periodontitis, contrasting with the results from gingival tissue samples meta-analysis of GPx enzyme.

目的:本系统综述从已有文献中汲取资料,探讨了酶和非酶抗氧化剂在牙周炎中的作用:研究方法包括从 2000 年到 2023 年在 PubMed、Science Direct 和 Wiley Online Library 等数据库中进行广泛的电子检索,并使用特定关键词进行交叉引用:最初的文献探索共收集到 766 篇文章。在对摘要进行深入研究后,有 693 篇文章因重复和与中心研究调查缺乏相关性而被排除在外。之后,留下 73 篇文章进行深入评估。经过定性评估,35 篇符合纳入标准的研究被选中,38 篇因不符合必要标准而被剔除。在这一选择范围内,对 11 篇为定量综合提供了一致数据的文章进行了荟萃分析。具体来说,对血清样本中谷胱甘肽(GSH)水平的分析表明,其标准化平均差(SMD)为-5.552 µg/mL (CI 95%: -9.078 to -2.026; P-0.002)。相比之下,对牙龈缝隙液(GCF)样本中谷胱甘肽过氧化物酶(GPx)的分析显示,总体 SMD 为 2.918 ng/µL(CI 95%:0.372-5.465;P-0.025),而唾液样本显示的总体 SMD 值为 0.709 U/l (95% CI:-1.907-3.325;P-0.596),微不足道:系统综述结果表明,牙周炎患者各种系统生物样本中的抗氧化酶明显减少,这与牙龈组织样本中 GPx 酶的荟萃分析结果形成了鲜明对比。
