Purpose: This survey aimed to investigate quality of communicating design features for the construction of cobalt chromium removable partial dentures (RPDs) among dentists in Riyadh, Saudi Arabia.

Materials and methods: A survey of nine commercial dental laboratories located in Riyadh was carried out. In each visit, master casts for cobalt chromium RPDs and dentists' prescriptions were examined. A quality score for the provided instructions was developed and ranged from 0 to 4. A zero score means that no instructions were sent from the dentist for the design of the RPD. A score of 4 means that instructions were provided for the design of four main elements of the RPD, i.e., shape of major connector, type of direct retainers, position of direct retainers, position of dental rests.

Results: 162 dentists' prescriptions for RPDs and related casts were assessed. The majority of RPD cases were designed by the dental technician alone (64.2%). Shape of the major connector was the most frequent element in dentists' prescriptions (35.8%). The mean quality score of dentists' instructions was 0.96 (sd=1.54). 18% of the provided instructions achieved quality score equal to 4. Prescriptions for Kennedy Class III cases achieved significantly higher mean quality score compared to Kennedy Class II cases (p<0.05). 16.7% of the evaluated casts had clearly defined rest seat preparation.

Conclusion: The results of this survey indicate inadequate quality of communicating the design features of cobalt chromium RPDs among practicing dentists in Riyadh, Saudi Arabia. The reliance on the dental technician to design the cast RPDs seems to be high.

目的:本调查旨在调查沙特阿拉伯利雅得牙医对钴铬可摘局部义齿(rpd)结构设计特征的沟通质量。材料和方法:对位于利雅得的九个商业牙科实验室进行了调查。在每次访问中,检查钴铬rpd的主铸件和牙医处方。为所提供的指导制定了一个质量评分,范围从0到4。0分意味着牙医没有给RPD的设计指示。得分为4分表示为RPD的四个主要元素的设计提供了说明,即主连接器的形状,直接固位器的类型,直接固位器的位置,牙托的位置。结果:对162名牙医的rpd处方及相关铸型进行评估。大多数RPD病例是由牙科技师单独设计的(64.2%)。主要接插件的形状是牙医处方中最常见的因素(35.8%)。牙医说明书质量评分平均为0.96分(sd=1.54)。提供的指导中有18%达到了4分的质量分数。Kennedy III类病例的处方平均质量得分明显高于Kennedy II类病例(p结论:本调查结果表明,沙特阿拉伯利雅得执业牙医对钴铬rpd设计特点的沟通质量不足。对牙科技师设计铸造rpd的依赖似乎很高。

Purpose: This study was done to analyse the influence of fixed dental prosthesis (FDP) on brain function by analysing power spectral density of partially edentulous patients.

Materials and methods: The study included unilateral missing mandibular molar replacement patients. The patients were restored with three-unit metal ceramic FDP restorations. The cognitive function was analysed with a mental state questionnaire. Power spectral density (PSD) analysis of EEG alpha waves was made pre- treatment, post treatment and 3 months after FDP treatment to analyse the brain function. The data in various phases were obtained before and after chewing. The results were statistically analysed.

Results: The mean pre and post treatment PSD was 0.0175 (SD ±0.0132) and 0.0178 (SD ±0.0135). The mean post treatment PSD after three months was 0.024 (SD± 0.019). The results were analysed with repeated ANOVA and were statistically significant. (p<0.01).

Conclusion: The study displayed improvement in brain function of partially edentulous patients with FDP rehabilitation.

Purpose: The aim of this study is to evaluate clinical success rate of resin-based fissure sealants applied at Istanbul University, Department of Pediatric Dentistry after 1 year of application.

Materials and methods: Children with at least one pair of caries-free permanent first molars with deep pits and fissures were included in the study. The ages of children ranged from 7-13 (mean age: 9.2±1.22). Resin-based fissure sealant was applied to the 322 fissures of the first permanent molars in 100 children. 12 months after the application, children were recalled for examination. Recall examinations were carried out by the same dentist. Fissure sealants were evaluated at 12th month by using Ryge criteria: Retention (R), precence of caries (PC), marginal adaptation (MA), marginal discoloration (MD) and cracking (C).

Results: 12 months after the application, all of the children were recalled and fissure sealants were examinated. Our findigs are: R: Alpha 95 (29.5%), Bravo: 143 (44.4%), Charlie: 84 (26%); PC: Alpha 274, Bravo 48 (14.9%); MD: Alpha 322; MA: Alpha 279, Bravo 43 (13.3%); C: Alpha 321, Bravo 1 (0.3%).

Conclusion: The preventive effects of the sealant are only maintained as long as it remains completely intact and bonded in place. After applying fissure sealants, patients must be recalled and sealants must be checked to provide retention and marginal adaptation.

Purpose: To evaluate the association between third molar (M3) agenesis and hypodontia and oligodontia in pediatric patients by using panoramic radiography.

Materials and methods: Panoramic radiographs of 1,471 patients (899 females; 572 males) and 5,884 teeth were retrospectively evaluated. The age and gender of the patients were recorded. Patients ages 9-15 years old were included in the study. The mean age was 12.76. The agenesis of M3 teeth and the relationship between M3 agenesis and hypodontia and oligodontia were recorded according to findings from the upper and lower jaw, in both the right and left locations, along with the number of M3 with agenesis. Data were analyzed using chi-square and McNemar tests (p<0.05).

Results: A total of 1,319 (89.7%) patients had all M3 teeth present in the mouth, while the other 152 (10.3%) had congenital agenesis in one or more teeth. The number of teeth in which M3 agenesis was seen, in order of the number of missing M3 teeth, the percentages were 2.6% for one, 2.4% for two, 1.0% for three and 4.3% for four missing teeth.Hypodontia was detected in 37 patients and oligodontia was detected in 3 patients.

Conclusion: The prevalence of M3 agenesis varies from one population to another. Two of the dental anomalies associated with M3 agenesis are hypodontia and oligodontia. In this study, M3 agenesis varied in terms of region and gender; hypodontia was also significantly higher in patients with missing mandibular M3.

Purpose: This study aimed to evaluate the effect of pain intensity levels and clinical symptoms on the treatment preferences of patients with endodontically involved teeth in a local Turkish population.

Subjects and methods: A total of 30 patients with symptomatic teeth requiring non-surgical root canal treatment were included in the study. The patients' demographic (age, gender, and education level) and diagnostic data (tooth type, pain intensity, response to percussion and palpation, presence of referred pain, and diagnosis) were analyzed. Data on the patients' explicit preferences (requested treatment, whether they are willing to accept a proposed extraction, choice of treatment if an anterior tooth was involved, and choice of treatment if the pain was not severe) as well as previous root canal treatment experiences were also analyzed. Pain intensity levels were evaluated using the Visual Analog Scale.

Results: Pain intensity levels had a significant effect on the treatment requested by the patient (p=0.001). Among the patients who requested extraction upon referral to the clinic, the rate of those who reported that they would not accept extraction if the pain was located in an anterior tooth was significantly lower than that of patients stating that they would refuse (p=0.039). The presence of referred pain also had a significant effect on the requested treatment (p=0.001).

Conclusion: The intensity of pain and the presence of referred pain influence patients' treatment preferences.

目的:本研究旨在评估疼痛强度水平和临床症状对土耳其当地人群根管受累牙齿患者治疗偏好的影响。对象与方法:本研究共纳入30例需要非手术根管治疗的有症状牙齿患者。分析患者的人口统计学(年龄、性别、文化程度)和诊断数据(牙齿类型、疼痛强度、对叩诊和触诊的反应、是否存在转诊疼痛和诊断)。研究还分析了患者明确的偏好数据(要求治疗,是否愿意接受建议的拔牙,是否涉及前牙的治疗选择,是否疼痛不严重的治疗选择)以及以前的根管治疗经验。使用视觉模拟量表评估疼痛强度水平。结果:疼痛强度水平对患者要求的治疗有显著影响(p=0.001)。在转介到诊所要求拔牙的患者中,如果疼痛位于前牙,不接受拔牙的比例明显低于拒绝拔牙的比例(p=0.039)。牵涉性疼痛的存在对所要求的治疗也有显著影响(p=0.001)。结论:疼痛强度和转诊疼痛的存在影响患者的治疗偏好。

Purpose: The aim of this study was to assess the effect of the Er:YAG laser on the clinical success of a hydrophilic fissure sealant over 12 months.

Subject and methods: This study was conducted on 132 permanent first molars from 44 (19 girls and 25 boys) patients aged 7-11 years. The teeth were divided into three groups. The first group (Group A-control) of teeth were etched with phosphoric acid, the second group of teeth (Group L) were etched with an Er:YAG laser, and the third group of teeth (Group A+L) were etched with both the Er:YAG laser and phosphoric acid. Clinical evaluations were performed at baseline and at 3-, 6-, 9- and 12-month follow-up visits. The data were analyzed with Pearson chi-square tests, Cochran Q tests and Kaplan-Meier analysis.

Results: At the end of the 12 months, total retention rates were 72.7%, 59.1%, and 65.9% in the acid group, the laser group and the laser and acid group, respectively. Although there was no statistically significant difference between group retention rates (p>0.05), the lowest retention rate was found in the laser group at the end of the 12-month follow-up period. No new caries were observed in any group during the study period.

Conclusion: Etching with the Er:YAG laser, phosphoric acid or a combination of both methods provided similar results for the clinical success of hydrophilic based fissure sealant.

目的:本研究的目的是评估Er:YAG激光对12个月亲水性裂隙密封胶临床成功的影响。对象与方法:对年龄在7 ~ 11岁的44例患者(女孩19例,男孩25例)132颗恒磨牙进行了研究。这些牙齿被分成三组。第一组(A组对照)采用磷酸刻蚀,第二组(L组)采用Er:YAG激光刻蚀,第三组(A+L组)采用Er:YAG激光和磷酸同时刻蚀。在基线和3个月、6个月、9个月和12个月随访时进行临床评估。采用Pearson卡方检验、Cochran Q检验和Kaplan-Meier分析。结果:12个月结束时,酸组、激光组和激光加酸组的总保留率分别为72.7%、59.1%和65.9%。随访12个月后,激光治疗组的留置率最低,但两组间留置率差异无统计学意义(p>0.05)。在研究期间,各组均未发现新龋。结论:Er:YAG激光蚀刻、磷酸蚀刻或两者联合蚀刻均可获得相近的临床效果。

Purpose: The boron and fluoride mainly accumulate in the bones and teeth of the human body. The purpose of this study is to determine boron or fluoride levels in the whole tooth, to evaluate the correlation between their levels and to compare these levels in primary/permanent, carious, and non-carious groups.

Materials and methods: The boron and fluoride levels of thirty-six teeth, separated such as primary carious (n=9) and non-carious (n=9), permanent carious (n=9) and non-carious (n=9), were determined by ICP-MS and ion-selective electrode, respectively.

Results: While boron levels were between 0.001 and 5.88 ppm, the fluoride levels were between 21.24 and 449.22 ppm. The boron level of non-carious teeth was higher than those of carious teeth in primary and permanent tooth groups. However, this difference was not statistically significant (p>0.05). The fluoride level of non-carious teeth was higher than those of carious teeth in primary (p=0.062) and permanent teeth groups (p=0.046). Negative correlation, found between boron and fluoride in all groups, was significant only in non-carious teeth group (r=-0.488, p=0.040).

Conclusion: The results of our study proved the importance of fluoride as a protective factor for dental caries once more. The boron levels in non-carious teeth were also higher than carious teeth. However, it was not significant. Moreover, there was negative correlation between teeth boron and fluoride levels. Therefore, it is necessary to conduct more detailed studies on the tooth boron level and its relation with caries formation and with fluoride levels.

用途:硼和氟化物主要积聚在人体的骨骼和牙齿中。本研究的目的是确定整个牙齿中的硼或氟水平,评估其水平之间的相关性,并比较原发性/永久性、龋齿组和非龋齿组的硼或氟水平。材料与方法:采用ICP-MS和离子选择电极分别测定原发性龋齿(n=9)和非龋齿(n=9)、永久性龋齿(n=9)和非龋齿(n=9) 36颗牙齿的硼、氟水平。结果:硼含量在0.001 - 5.88 ppm之间,氟含量在21.24 - 449.22 ppm之间。乳牙组和恒牙组无龋组的硼含量均高于龋组。但差异无统计学意义(p>0.05)。乳牙组非龋牙组氟含量高于龋牙组(p=0.062)和恒牙组(p=0.046)。硼和氟在所有组中呈负相关,仅在非龋齿组中显著(r=-0.488, p=0.040)。结论:本研究结果再次证明了氟化物作为龋病保护因子的重要性。非蛀牙的硼含量也高于蛀牙。然而,这并不显著。此外,牙齿硼和氟化物水平呈负相关。因此,有必要对牙齿硼含量及其与龋齿形成和氟化物含量的关系进行更详细的研究。

Purpose: To evaluate the effects of surface coating and one-year water storage on the flexural strength of fluoride-releasing restorative materials.

Materials and methods: Forty specimens were prepared from each material; GCP Glass Fill (GCP), Amalgomer CR (AHL), Zirconomer (Shofu), Fuji IX GP Capsule (GC), Beautifil II (Shofu), Estelite Σ Quick (Tokuyama) and reliaFIL LC (AHL). The specimens were randomly divided into two groups; surface coated with G-Coat Plus (GC) and uncoated. Each group was subdivided into two groups stored in distilled water at 37◦C for 24 h and 1 year before testing (n=10). The flexural strength was evaluated using three-point bending test according to the ISO 4049:2009 standard using a universal testing machine. After flexural strength test, a cross-section of the coated specimens was evaluated with scanning electron microscopy (SEM).

Results: A significant increase was observed on the flexural strength of Amalgomer CR, Zirconomer and Fuji IX GP after 24 h when G-Coat Plus was applied (p<0.05). This significant increase was observed on the flexural strength of only Amalgomer CR and Zirconomer after 1 year (p<0.05). The highest flexural strength was obtained with Beautifil II, Estelite Σ Quick and reliaFIL LC after 24 h and 1 year (p<0.05). After 1 year, there was decrease on the flexural strength of the other materials except Beautifil II, Estelite Σ Quick and reliaFIL LC.

Conclusion: The resin coating improved the flexural strength of some glass ionomer-based materials but the water aging decreased the same physical properties.

目的:评价表面涂覆和1年保水对含氟修复材料抗弯强度的影响。材料和方法:每种材料各制备40个标本;GCP玻璃填充剂(GCP),汞合金CR (AHL),锆合金(Shofu),富士IX GP胶囊(GC),美丽II (Shofu), Estelite Σ Quick (Tokuyama)和reliaFIL LC (AHL)。将标本随机分为两组;表面涂覆G-Coat Plus (GC)和未涂覆。每组再分为两组,分别在37℃蒸馏水中保存24 h和1年,再进行试验(n=10)。根据ISO 4049:2009标准,使用万能试验机,采用三点弯曲试验评估抗弯强度。在抗弯强度测试后,用扫描电子显微镜(SEM)对涂层试样的横截面进行了评估。结果:G-Coat Plus处理24h后,汞合金CR、锆合金和富士IX GP的抗弯强度均有显著提高(p结论:树脂涂层提高了部分玻璃离子基材料的抗弯强度,但水老化降低了相同的物理性能。

Purpose: The aim of the study is to present a photogrammetric technique using standardized occlusal photographs to perform Bolton's analysis and assess reliability of this new method with plaster study casts.

Materials and methods: The study was conducted on 16 subjects (8 males, 8 females), aged 18-25 years. Standardized occlusal photographs and plaster study casts were obtained. The occlusal photographs were calibrated in Nemoceph® software. Mesio-distal dimensions of all teeth up to first molars were calculated and Bolton's analysis was performed. Similarly, a digital calliper with 0.1 mm sensitivity was used to measure mesio-distal dimensions of all teeth on plaster study casts to perform Bolton's analysis. 28 parameters were measured on study models and corresponding occlusal photographs. Paired t test and intraclass correlation tests were carried out to test validity and reliability of the photogrammetric method. An intraclass correlation test was calculated for 4 derived parameters to test reliability of Bolton's analysis measurements obtained from occlusal photographs as compared to study models.

Results: All 28 parameters showed a statistically significant and excellent correlation (r>.80) in the Intra Class Correlation test. 4 variables used to calculate Bolton's analysis showed statistically significant correlation (r>.96) in the intraclass correlation test.

Conclusion: Photogrammetry is a reliable tool to measure mesio-distal tooth size. Bolton's analysis from standardized occlusal photographs using the described photogrammetric technique can be used as an effective clinical tool.

From December 12, 2019, a pandemic of acute respiratory syndrome, the novel human coronavirus disease (COVID-19), caused by a novel β-coronavirus (2019- nCoV) began to grow globally by person-to-person transmission. The production of airborne material during aerosol generating dental procedures would expose dental team and patients to remarkable risk of transmission concerning the faceto- face communication and splattered saliva, blood, and other body fluids. Dental professionals can be a substantial help in preventing the transmission of COVID-19. This study has reviewed relevant current evidences in literature that has addressed the role of saliva and the threats that may be inherent in transmission of the disease during dental procedures. The study also offers feasible proactive and preventive measures for dental practice during the outbreak to block possible person-toperson or indirect transmission in dental settings.

从2019年12月12日起,由新型β冠状病毒(2019- nCoV)引起的急性呼吸综合征(新型人类冠状病毒病)大流行开始在全球范围内以人传人的方式蔓延。在产生气溶胶的牙科手术过程中,空气传播物质的产生将使牙科团队和患者面临通过面对面交流和飞溅的唾液、血液和其他体液传播的显著风险。牙科专业人员可以在预防COVID-19传播方面提供实质性帮助。本研究回顾了目前文献中的相关证据,这些证据解决了唾液的作用以及在牙科手术过程中疾病传播中可能固有的威胁。该研究还为疫情爆发期间的牙科诊所提供了可行的主动和预防措施,以阻止可能的人与人之间或牙科环境中的间接传播。
