Objective

This study aimed to associate the number of present teeth and pairs of natural teeth with obesity in older adults (≥ 60 years old).

Methods

This study used a probabilistic and representative sample from two southern Brazilian cities (Cruz Alta and Veranópolis). Data collection took place at the participants' households. Obesity was defined as body mass index ≥ 30Kg/m². Oral examination was performed by calibrated researchers. Pairs of natural teeth were defined as pairs of antagonistic teeth. Sociodemographic, behavioural, medical, and dental history variables were also collected. Adjusted models were constructed using Poisson, considering different definitions of pairs of natural teeth (α < 5%). Independent analyses were performed for the whole sample and for each city.

Results

The study included 559 individuals. Prevalence of obesity was 29.9%. Number of present teeth was 7.80 ± 8.68, while the total number of pairs of teeth was 2.16 ± 3.92. No significant association was detected between obesity and the number of teeth present (p = 0.254) or total pairs of natural teeth present (p = 0.065). However, for each pair of natural molars, the prevalence ratio (PR) of obesity was reduced by 22% (95% CI: 0.64–0.95). Similarly, for each functional tooth unit present, the PR for obesity was reduced by 4% (95% CI: 0.93–0.99). To the most significant associations, a weak effect size was detected. Similar results were detected in Veranópolis, but no significant association was observed in Cruz Alta.

Conclusion

Higher numbers of pairs of natural molars, rather than the higher number of overall natural teeth, are associated with lower prevalence of obesity among older adults.

目的：本研究旨在探讨老年人（≥60岁）的现有牙齿数量和天然牙齿对与肥胖的关系。方法：本研究采用巴西南部两个城市（Cruz Alta和Veranópolis）的概率和代表性样本。数据收集在参与者的家中进行。肥胖定义为体重指数≥30Kg/m2。口腔检查由校准的研究人员进行。对天然牙被定义为对拮抗牙。还收集了社会人口学、行为、医学和牙科史变量。考虑对天然牙的不同定义，采用泊松法构建调整后的模型（α）。肥胖患病率为29.9%。现牙数为7.80±8.68，总牙对数为2.16±3.92。肥胖与存在的牙齿数量（p = 0.254）或存在的天然牙齿总数（p = 0.065）之间没有显著关联。然而，对于每一对天然磨牙，肥胖患病率（PR）降低了22% （95% CI: 0.64-0.95）。同样，对于存在的每个功能牙齿单元，肥胖的PR降低了4% （95% CI: 0.93-0.99）。对于最显著的关联，检测到弱效应量。在Veranópolis中也发现了类似的结果，但在Cruz Alta中没有观察到显著的关联。结论：老年人中，天然磨牙对的数量越多，肥胖的发病率就越低。

Background: Dentine hypersensitivity (DH) is a common oral condition. The management of DH has been challenging with various treatment options, including in-office and home care.

Objective: To evaluate the efficacy of hydroxyapatite-containing toothpaste for the reduction of DH pain compared to potassium nitrate-containing toothpaste in short-term use.

Methods: A randomised; non-blinded clinical study involved 39 participants in the age group range 18-51 years. The patients were randomly divided into two groups. The test group (n = 19) was provided with hydroxyapatite toothpaste, while the control group (n = 20) received potassium nitrate toothpaste. Volunteers were examined using an air blast as the stimulus. DH pain scores (Visual Analogue Scale [VAS] and Schiff) were recorded at baseline, 2 weeks and 4 weeks.

Results: Both toothpastes significantly relieved DH in response to air-blast stimulus (p < 0.001). The relief of sensitivity was efficacious after 2 and 4 weeks for both toothpastes. The efficacy of hydroxyapatite toothpaste was comparable to that of potassium nitrate toothpaste.

Conclusion: This study shows that hydroxyapatite in higher concentrations has a similar efficacy in relieving DH as potassium nitrate.

Clinical significance: DH affects the quality of life. The use of a desensitising toothpaste can relieve DH. However, there is no gold-standard management for DH. The outcome of this study supports the use of hydroxyapatite toothpaste for DH relief.

背景：牙本质过敏（DH）是一种常见的口腔疾病。卫生署的管理一直面临各种治疗方案的挑战，包括办公室和家庭护理。目的：评价含羟基磷灰石牙膏与含硝酸钾牙膏短期使用对减轻DH疼痛的疗效。方法：随机；非盲临床研究涉及39名年龄在18-51岁之间的参与者。患者随机分为两组。试验组（n = 19）给予羟基磷灰石牙膏，对照组（n = 20）给予硝酸钾牙膏。志愿者们接受了空气爆炸作为刺激的检查。分别在基线、2周和4周记录DH疼痛评分（视觉模拟评分法[VAS]和Schiff）。结果：两种牙膏均能显著降低空气冲击波刺激下的DH (p)。结论：本研究表明，高浓度羟基磷灰石与硝酸钾具有相似的DH缓解效果。临床意义：DH影响生活质量。使用脱敏牙膏可以减轻DH。然而，对于DH并没有黄金标准的管理。本研究的结果支持使用羟基磷灰石牙膏的DH救济。

Objectives

This workforce modelling research aims to model the future dental workforce in line with the full enactment of the revised Dental Act, which permits dental therapists to practice in private dental sectors.

Method

A validated systems dynamics model was used to examine the interaction between the population baseline need, demand for and the supply of dental care services across public and private sectors between 2015 and 2030. Simulations were made based on evidence drawn from previous studies and government data policy. The need/demand and supply sub-models were integrated in relation to clinical hours to explore the potential of over-or undersupply of dentists and therapists, which were then converted to workforce numbers.

Results

The model suggests that the demand for Malaysian dentists and dental therapists is expected to increase by over 27.2% and 2.6%, respectively, across the simulation period and the demographic disease trends. This result indicates the need for an expanded dental workforce. However, a potential oversupply of public dental therapists and private dentists was projected by 2025. Furthermore, a potential undersupply of public dentists was observed throughout the simulation period.

Conclusion

There is an apparent mismatch between the population demand and workforce supply across sectors. The model findings indicate the need for additional discussion and scrutiny of regulations allowing dental therapists to operate in the private sector to inform workforce policy and planning.

目的：这个劳动力建模研究的目的是模拟未来的牙科劳动力符合全面颁布修订的牙科法，这允许牙科治疗师在私营牙科部门的做法。方法：采用经过验证的系统动力学模型，研究2015年至2030年期间公共和私营部门牙科保健服务的人口基线需求、需求和供应之间的相互作用。模拟是根据以前的研究和政府数据政策得出的证据进行的。需要/需求和供应子模型与临床时间相结合，以探索牙医和治疗师供应过剩或不足的可能性，然后将其转换为劳动力数量。结果：该模型表明，在模拟期间和人口疾病趋势期间，马来西亚牙医和牙科治疗师的需求预计将分别增长27.2%和2.6%以上。这一结果表明需要扩大牙科劳动力。然而，预计到2025年，公共牙科治疗师和私人牙医可能会供过于求。此外，在整个模拟期间，我们观察到公立牙医的潜在供应不足。结论：各部门的人口需求和劳动力供给之间存在明显的不匹配。模型研究结果表明，需要进一步讨论和审查允许牙科治疗师在私营部门开展业务的法规，以便为劳动力政策和规划提供信息。

Objective: To compare the efficacy of 0.12% chlorhexidine (CHX) mouthrinse alone and combined with brushing in controlling plaque and reducing gingivitis.

Methods: This study was a randomised clinical trial with an examiner-blind, split-mouth experiment. Thirty participants were scaled, polished and instructed on oral hygiene for 2 weeks before commencing a 14-day non-brushing split-mouth trial. After 2 weeks, the participants teeth were polished, then randomly allocated to the right or left non-brushing side groups and instructed to rinse with 0.12% CHX twice daily for 2 weeks. The evaluation of the plaque index and gingival index was performed by a blinded, calibrated investigator.

Results: Twenty-seven subjects completed the study (right non-brushing: n = 13/left non-brushing: n = 14). The participants' characteristics were not significantly different between groups. After 2-week rinsing with CHX, post-treatment PI and GI were significantly lower compared to baseline on both the non-brushing and brushing sides (p < 0.000, 0.001, 0.007 and 0.001, respectively). GI reduction was significantly greater on the brushing sides (mean difference -0.220, 95% CI -0.476 to -0.036, p = 0.016), though PI reduction showed no significant difference between interventions (ΔPI: 1.23 vs. 1.01, mean difference -0.139, 95% CI -0.251 to -0.027, p = 0.091).

Conclusion: There was no difference in plaque inhibition when rinsing with CHX as an adjunct to mechanical plaque control compared with CHX alone in a split-mouth design.

Trial registration: Thai Clinical Trials Registry: TCTR20200312006.

目的：比较0.12%氯己定（CHX）漱口水单用与联合刷牙控制菌斑、减轻牙龈炎的疗效。方法：本研究为随机临床试验，采用考官盲、裂口实验。30名参与者在开始为期14天的不刷牙分口试验之前，进行了为期2周的口腔卫生测量、擦亮和指导。2周后，参与者的牙齿被抛光，然后随机分配到右侧或左侧不刷牙组，并指示每天用0.12% CHX冲洗两次，持续2周。牙菌斑指数和牙龈指数的评估由一名盲法校准的研究者进行。结果：27名受试者完成了研究（右侧未刷牙：n = 13/左侧未刷牙：n = 14）。受试者的特征在两组间无显著差异。用CHX冲洗2周后，治疗后的PI和GI在未刷牙和刷牙侧均明显低于基线(p结论：在裂口设计中，用CHX作为机械斑块控制的辅助冲洗与单独使用CHX相比，在斑块抑制方面没有差异。试验注册：泰国临床试验注册：TCTR20200312006。

Introduction

Replacing missing teeth has always been a priority in dentistry. With recent clinical advancements, dental implants are the treatment of choice and the global demand for implants has drastically increased. Implant maintenance is fundamental to its long-term success. This study aimed to assess the attitudes towards clinical assessment, radiographic protocols and overall knowledge of implant maintenance protocols among dentists in the Makkah region.

Methods

A cross-sectional study was conducted among registered dentists of the Saudi Commission for Health Specialties (SCFHS) in the Makkah region using an electronic questionnaire. A total of 183 dentists were conveniently sampled and categorised into groups based on their years of clinical expertise and chronological generations: Generations (B), (X), (Y) and (Z). Holistic knowledge and clinical compliance were sorted into low, moderate and high levels.

Results

The study showed significance among expert dentists (95.3%, n = 41) for the evaluation of keratinised tissue adjacent to implants as compared to that among novice dentists (82.9%, n = 116; p = 0.040), and in the routine use of panoramic radiographs for examination of implants among different generations of dentists (p = 0.017). The total scores showed moderate overall knowledge and clinical compliance among dentists in the Makkah region.

Conclusion

Generational differences were detected among different dentists in only a few minor aspects of the implant maintenance protocol, with moderate overall levels of knowledge and clinical compliance. Nevertheless, it is critical to understand that generation is simply one factor that determines behaviour. Continuing education and cumulative clinical expertise throughout the years of practice have an impact on implant maintenance practices.

简介：补牙一直是牙科的首要任务。随着最近临床的进步，种植牙是治疗的选择，全球对种植体的需求急剧增加。种植体维护是其长期成功的基础。本研究旨在评估麦加地区牙医对临床评估、放射治疗方案和种植体维护方案的总体知识的态度。方法：采用电子问卷对沙特卫生专业委员会（SCFHS）在麦加地区的注册牙医进行横断面研究。共有183名牙医被方便地抽样，并根据他们的临床经验年数和时间代际进行分组：(B)、(X)、(Y)和(Z)代。整体认知水平和临床依从性分为低、中、高水平。结果：专家（95.3%,n = 41）对种植体邻近角化组织的评价高于新手（82.9%,n = 116; p = 0.040），不同代际牙医对种植体常规使用全景x线片的评价差异有统计学意义（p = 0.017）。总分显示适度的总体知识和临床依从性的牙医在麦加地区。结论：不同牙医在种植体维持方案的几个小方面存在代际差异，总体知识水平和临床依从性中等。然而，重要的是要明白，世代只是决定行为的一个因素。在多年的实践中，继续教育和累积的临床专业知识对种植体维护实践有影响。

Objectives

The COVID-19 pandemic emerged in late 2019 and led to unprecedented global lockdowns, disrupting numerous industries, including dentistry. This study aimed to investigate the practicing conditions, personal protective equipment (PPE) usage, and impact of the pandemic on dental hygienists (DHs) in Japan, where strict lockdowns were not enforced but compliance to reduce infection spread was high, and healthcare clinics remained open.

Methods

This cross-sectional study utilised an online survey distributed to 354 dental hygiene vocational school graduates in Tokyo, Japan, between May 9 and June 5, 2022. The questionnaire, adapted from a New Zealand Dental & Oral Health Therapists Association survey, collected data on demographics, practicing conditions, the impact of COVID-19 on DHs, personal protective equipment usage, and stress levels during different COVID-19 waves.

Results

Out of 354 DHs, 77 (21.8%) provided valid responses. Most (94.8%) worked in Tokyo and neighbouring areas, with 85.7% working at private institutions. The COVID-19 pandemic led to ceasing work (11.3%), reduced working days (27.3%), decreased patient visits (49.4%), and changes in personal protective equipment usage. High-stress levels peaked during the first wave (46.8%) and fell during the fifth (37.7%) and sixth (11.7%) waves. The most common stress factors were related to inhibiting stress relief, infection risk, and protection.

Conclusion

The COVID-19 pandemic impacted DHs’ working conditions, personal protective equipment usage, and stress levels in Japan. Despite not facing a strict lockdown, DHs, who have experienced detrimental changes in the work environment, will need post-pandemic support that considers droplet infection protection and practitioner well-being.

2019年底出现的COVID-19大流行导致了前所未有的全球封锁，扰乱了包括牙科在内的许多行业。本研究旨在调查日本牙科卫生人员的执业条件、个人防护装备（PPE）的使用情况以及大流行对牙科卫生人员的影响。日本没有实施严格的封锁，但减少感染传播的合规性很高，卫生保健诊所仍然开放。方法：这项横断面研究利用了一项在线调查，该调查于2022年5月9日至6月5日在日本东京对354名口腔卫生职业学校毕业生进行了调查。该问卷改编自新西兰牙科和口腔健康治疗师协会的一项调查，收集了人口统计数据、执业条件、COVID-19对DHs的影响、个人防护装备的使用以及不同COVID-19浪潮期间的压力水平。结果：354例DHs中，有效应答77例（21.8%）。大部分（94.8%）在东京及邻近地区工作，85.7%在私营机构工作。COVID-19大流行导致停工（11.3%），工作日减少（27.3%），就诊人数减少（49.4%），个人防护装备使用情况发生变化。高压力水平在第一波达到峰值（46.8%），在第五波（37.7%）和第六波（11.7%）下降。最常见的应激因素与抑制应激缓解、感染风险和保护有关。结论：2019冠状病毒病大流行影响了日本卫生工作者的工作条件、个人防护装备使用和压力水平。尽管没有面临严格的封锁，但经历了工作环境有害变化的卫生部门将需要大流行后的支持，考虑到飞沫感染保护和从业人员的福祉。

Objectives

The aim of the study was to analyse the effectiveness of some interproximal tools to remove bacterial biofilm on implant-prosthesis rehabilitations with different morphological characteristics.

Methods

3 temporary crowns made by polymethylmethacrylate resin with different emergency profiles (20°, 30° and 40°) screwed onto an implant placed on a resin model at different implant depth relative to bone crest (bone level, subcresal at 1 mm, supracrestal at 1 mm). After coating surfaces with a contact detection spray, the screwed crowns were cleaned with different interproximal tools: the Oral-B Super FlossTM, the TePe Bridges & Implant Floss, the cylindrical brush TePe Original, the conical brush GUM TRAV-LER and the TePe EasyPickTM soft pick. At the end of each use the crowns were photographed and analysed using TextCompare software. For each tool, five measurements were taken per interproximal surface. The data were analysed statistically.

Results

All the tools were effective in reducing the interproximal plaque. Lower results were obtained by the TePe EasyPickTM soft pick (min-max cleaned surface 47%–68%). In implant-prosthesis with emergence angles below 30° the interproximal brushes were more efficient (cleaned area min-max 74%–75%), while with greater angles implant floss was more effective (cleaned area min-max 73%–76%).

Conclusion

Brushes for smaller emergence profiles and subcrestal implants and floss for crowns with larger emergence profiles and supracrestal implants are recommended.

目的：分析几种近端间工具去除细菌生物膜在不同形态特征种植体修复中的效果。方法：用聚甲基丙烯酸甲酯树脂制作3个临时冠，不同的应急轮廓（20°，30°和40°），螺钉固定在树脂模型上的种植体上，种植体相对于骨嵴的深度不同（骨水平，骨下1mm，骨上1mm）。在用接触检测喷雾涂覆表面后，使用不同的近端间工具：Oral-B Super FlossTM， TePe Bridges & Implant Floss， TePe Original圆柱刷，锥形刷GUM TRAV-LER和TePe EasyPickTM软剔牙。在每次使用结束时，冠被拍照并使用TextCompare软件进行分析。对于每个工具，每个近端间表面进行5次测量。对数据进行统计学分析。结果：所有工具均能有效减少近端间牙菌斑。TePe easyypicktm软pick的结果较低（最小-最大清洁表面47%-68%）。在出现角小于30°的种植体-假体中，近端间刷的效率更高（清洁面积最小-最大74%-75%），而更大角度的种植牙线的效率更高（清洁面积最小-最大73%-76%）。结论：牙冠出苗轮廓小、牙冠下种植宜使用毛刷，牙冠出苗轮廓大、牙冠上种植宜使用牙线。

Objectives

This study aimed to quantify common microorganisms present in the toothbrushes of the participants and assess the level of their knowledge regarding this issue.

Methods

Participants (n = 30) answered a questionnaire designed to elicit information which could be used to identify the habits regarding the use of toothbrushes and their storage. The participants were randomly selected and divided into two groups: Group 1 used a new toothbrush for 1 month and Group 2 used a new toothbrush for 3 months. Each participant was then instructed to store the toothbrush as usual and return it in a sterile bag. The toothbrush heads were cut for microbiological analyses. Cultivation media for the identification of Streptococcus mutans, Staphylococcus aureus, and Enterobacteriaceae were used and colony-forming units were counted after the incubation period. Statistical analyses were performed by using a two-way ANOVA test.

Results

The majority of the participants had never received professional advice regarding the storage and disinfection of toothbrushes (93%) and they were unaware of the contamination degree of their toothbrushes (73%). It was not possible to verify a statistically significant difference between the 1-month and 3-month groups for S. mutans (p > 0.05). However, the evaluation of contamination by S. aureus and Enterobacteriaceae revealed statistically significant differences between these groups (p < 0.05).

Conclusions

It was concluded that S. mutans, S. aureus, and Enterobacteriaceae were found in the toothbrushes analysed. However, the poor knowledge of the participants about the degree of contamination of their toothbrushes is a challenge to overcome, as most of them were unaware of the care required for toothbrush storage.

目的：本研究旨在量化参与者牙刷中常见的微生物，并评估他们对这一问题的知识水平。方法：参与者（n = 30）回答了一份问卷，该问卷旨在获得有关牙刷使用习惯和牙刷储存习惯的信息。随机选择受试者分为两组：第一组使用新牙刷1个月，第二组使用新牙刷3个月。然后，每个参与者被指示像往常一样储存牙刷，并将其放入无菌袋中。剪下牙刷头进行微生物学分析。使用变形链球菌、金黄色葡萄球菌和肠杆菌科的鉴定培养基，孵育后计数菌落形成单位。采用双因素方差分析进行统计分析。结果：大多数参与者（93%）从未接受过有关牙刷储存和消毒的专业建议，他们不知道牙刷的污染程度（73%）。无法验证1个月组和3个月组之间突变链球菌的统计学差异（p < 0.05）。然而，对金黄色葡萄球菌和肠杆菌科的污染评估显示，两组间差异有统计学意义(p)。结论：在分析的牙刷中发现了变形链球菌、金黄色葡萄球菌和肠杆菌科。然而，参与者对牙刷污染程度的了解不足是一个需要克服的挑战，因为他们中的大多数人都不知道牙刷存放时需要注意什么。

Background: The internet is an important source of health information for the population. There is robust evidence about the efficacy of mouthwashes in the prevention and treatment of oral diseases. However, many websites containing mouthwash-related content may display misinformation and be challenging to read and understand. Thus, this study evaluates the quality of information available about mouthwashes on Brazilian websites.

Methods: A total of 100 websites were evaluated across Google, Bing and Yahoo!. The websites were organised into rankings according to their order of appearance on each of the four search engines. Two independent examiners assessed the quality of the websites using the DISCERN questionnaire and the Journal of American Medical Association (JAMA) benchmark criteria. The readability of the sites was assessed by the Flesch Reading Ease adapted to Brazilian Portuguese (FRE-BP). The content of the websites was categorised according to the presence or absence of information relevant to the theme. Statistical analysis was performed using Spearman rank correlation coefficient, Mann-Whitney U test, Kruskal-Wallis test and Dunn post hoc test.

Results: A total of 32 sites were analysed. Web content was considered of poor quality by DISCERN (mean 37.46 ± 8.28) and JAMA (mean 1.37 ± 0.87) scores, presenting difficult reading levels (FRE-BP: mean 44.04 ± 9.89).

Conclusions: The mouthwash-related content available on Brazilian websites was considered of low quality and difficult to read.

背景：互联网是人口健康信息的重要来源。关于漱口水在预防和治疗口腔疾病方面的功效，有强有力的证据。然而，许多含有漱口水相关内容的网站可能会显示错误信息，难以阅读和理解。因此，本研究评估了巴西网站上有关漱口水的信息质量。方法：通过b谷歌、Bing和Yahoo!对100个网站进行评价。这些网站根据它们在四个搜索引擎上的出现顺序进行排名。两名独立审查员使用DISCERN问卷和美国医学协会杂志（JAMA）基准标准评估了网站的质量。网站的可读性采用巴西葡萄牙语版Flesch Reading Ease （fr - bp）进行评估。网站的内容根据是否存在与主题相关的信息进行分类。统计学分析采用Spearman秩相关系数、Mann-Whitney U检验、Kruskal-Wallis检验和Dunn事后检验。结果：共分析32个部位。根据DISCERN评分（平均37.46±8.28）和JAMA评分（平均1.37±0.87），网页内容被认为质量较差，呈现困难的阅读水平（fr - bp：平均44.04±9.89）。结论：巴西网站上的漱口水相关内容被认为质量较低且难以阅读。
