Periodontal disease can be treated in several ways. This paper reviewed whether antimicrobial photodynamic therapy (aPDT) in addition to scaling and root planing (SRP) produces improved clinical results over systemic antibiotics (ABs) in conjunction with SRP in adults with periodontitis. Studies were searched using the following electronic databases: MEDLINE, the Cochrane Database of Systematic Reviews, and the Web of Science Core Collection up to and including November 2018. Four randomized controlled trials (RCTs) were reviewed to maximise the reliability of the evidence. All participants suffered from either chronic or aggressive periodontitis and each study contained SRP as an adjunct to ABs or aPDT. To determine whether groups showed improvement after treatment, the outcome parameters chosen were probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP). Despite finding significant improvements in all groups, the differences among groups were not consistently statistically significant. The lack of homogeneity in the results among these studies indicates that it was not possible to determine a conclusion about whether aPDT or AB as an adjunct to SRP provides better improvements in periodontitis as measured by PD, CAL, and BOP. Further studies with more similar study designs are required before firm conclusions can be deduced.
牙周病有几种治疗方法。本文综述了抗菌素光动力疗法(aPDT)加刮治和刨根(SRP)是否比全身抗生素(ABs)联合SRP治疗牙周炎患者的临床效果更好。使用以下电子数据库检索研究:MEDLINE、Cochrane系统评价数据库和Web of Science核心合集，截止至2018年11月。我们回顾了四项随机对照试验(rct)，以最大限度地提高证据的可靠性。所有参与者都患有慢性或侵袭性牙周炎，每个研究都包含SRP作为ABs或aPDT的辅助药物。为了确定各组治疗后是否有改善，选择的结局参数是探探深度(PD)、临床附着水平(CAL)和探探出血(BOP)。尽管发现所有组都有显著的改善，但组间的差异在统计学上并不一致。缺乏同质性在这些研究结果表明,它是不可能确定一个结论是否aPDT或AB作为兼职SRP牙周炎以提供更好的改善PD,卡尔和防喷器。在得出确定的结论之前，需要进行更多类似研究设计的进一步研究。

This controlled in vitro study compared the effects of varying the thickness of a TiO2 layer on cellular activity using commercially available miniscrew samples with identical surface features to derive information with direct clinical impact. Titanium grade V plates with four different thicknesses of TiO2 layer/color were used: absent/gray (Control group), 40–50 nm/pink (Pink group), 130 nm/gold (Gold group) and 140 nm/rosé (Rosé group). In vitro experiments used Saos-2 cells and included cell growth analysis, phospho-Histone H3 and procollagen I staining, cell viability analysis, and a cell migration assay at 12, 24, 40 and to 48 h. Few differences were seen among the groups, with no clear behavior of cellular activity according to the TiO2 thickness. The Control group showed a greater cell count. Phospho-Histone H3 staining was similar among the groups and procollagen I staining was greater in the Rosé group. Cell viability analysis showed a significant difference for live cell counts (greater in the Rosé group) and no difference for the dead cell counts. The cell migration assay showed a delay for the Rosé group up to 40 h, where full repopulation of cell-free areas was obtained at 48 h. The results suggest that the TiO2 layers of the commercial miniscrews have minimal biological effects, including cytotoxicity, with possibly negligible or minimal clinical implications.

Primary care and healthcare providers can facilitate children's timely referral to a dental home. However, there are few studies of providers' oral health knowledge and clinical skills. This study aims to improve future healthcare providers' knowledge, confidence, attitude, and clinical competence in assessing children's oral health. Sixty-five health professional students participated in a 10-week didactic and clinical curriculum on children's oral health. Fifty students completed pre- and post-training questionnaires and were assessed in their knowledge, confidence, and attitude. Calibrated examiners graded students' clinical skills on a 24-point grading criterion. Descriptive statistics, paired sample t-test, and Pearson correlation were used in data analyses. Students were in dentistry (46%), nursing (28%), medicine (22%), and pharmacy (3%). Students significantly improved in knowledge (t = -7.71, p < 0.001), confidence (t = -10.30, p = <0.001), and attitude (t = -4.24, p = <0.001). Students on average scored 83% on clinical competence, with the highest average for fluoride varnish application (96%) and lowest for providing anticipatory guidance (69%). There was a moderate correlation between improvement in knowledge and their clinical skills (r = 0.39, p = 0.010). Interprofessional education improves students' knowledge, confidence, attitude, and clinical competence in assessing children's oral health. Such education is necessary in guiding future providers to gain adequate competence in serving children's oral health needs.
初级保健和医疗服务提供者可以帮助儿童及时转诊到牙科之家。然而，有关医疗服务提供者口腔健康知识和临床技能的研究却很少。本研究旨在提高未来医疗服务提供者在评估儿童口腔健康方面的知识、信心、态度和临床能力。65 名保健专业学生参加了为期 10 周的儿童口腔健康教学和临床课程。50 名学生填写了培训前后的调查问卷，并对他们的知识、信心和态度进行了评估。校准考官根据 24 分的评分标准对学生的临床技能进行评分。数据分析采用了描述性统计、配对样本 t 检验和皮尔逊相关分析。学生来自牙科（46%）、护理（28%）、医学（22%）和药学（3%）。学生在知识（t = -7.71，p < 0.001）、信心（t = -10.30，p = t = -4.24，p = r = 0.39，p = 0.010）方面均有明显提高。跨专业教育提高了学生在评估儿童口腔健康方面的知识、信心、态度和临床能力。这种教育对于指导未来的医疗服务提供者在满足儿童口腔健康需求方面获得足够的能力是必要的。

The purpose of this study was to investigate the bonding capacity of composite core build-up materials with prefabricated glass fiber-reinforced posts possessing different coronal morphologies. Five post types (Archimede Line (ARL), Fibrekleer (FBK), Glassix (GLX), Matrix Plus (MTP), and ParaPost White (PRW) and three core build-up materials (ClearfilPhoto Core (CPC), ClearfilDC Core (CDC), ClearfilNew Bond (CNB) of different curing modes (light-, self-, dual-cured respectively) were selected. The coronal part was embedded in the core build-up materials and the specimens were loaded under tensile force up to failure. The reliability (β) and characteristic life (σο, in Ν) of the debonding force were evaluated by Weibull statistics and the debonded specimens were subjected to failure mode analysis. The results showed that ARL, MPT posts were the most and GLX the least retentive, despite the core build-up material used. CPC provided the highest retention with four posts (FBK, GLX, MTP, and PRW), without statistically significant differences from CDC in two (FBK and MTP) and CNB in one (PRW). CPC and CDC were the most reliable core materials for two posts (ARL and PRW), with no statistically significant difference from CNB in three (FBK, GLX, and MTP). GLX and PRW demonstrated the highest (93%) incidence of post detachment from core, whereas FBK demonstrated the highest percentage of core material fracture, with most fractures occurring in CDC (57%). Post fractures were most prominent in MTP when combined with CNB. The presence of specific coronal retentive features did not essentially ensure increased strength with the core material, due to their delamination.
本研究的目的是研究具有不同冠状形态的预制玻璃纤维增强桩与复合核心构筑材料的结合能力。选择了5种不同固化方式(光固化、自固化、双固化)的桩型(archmede Line (ARL)、Fibrekleer (FBK)、Glassix (GLX)、Matrix Plus (MTP)和ParaPost White (PRW))和3种堆芯材料(ClearfilPhoto core (CPC)、ClearfilDC core (CDC)、ClearfilNew Bond (CNB))。冠状部分埋入核心堆砌材料中，试件承受拉伸载荷直至破坏。采用威布尔统计法对脱粘力的可靠性(β)和特征寿命(σο， Ν)进行了评价，并对脱粘试样进行了失效模式分析。结果表明，尽管使用了堆芯材料，但ARL、MPT桩的固位率最高，GLX桩的固位率最低。CPC提供了最高的四个职位(FBK, GLX, MTP和PRW)，与CDC的两个职位(FBK和MTP)和CNB的一个职位(PRW)相比，差异无统计学意义。CPC和CDC是两个位点(ARL和PRW)最可靠的核心材料，与CNB在三个位点(FBK、GLX和MTP)上无统计学差异。GLX和PRW显示出最高的(93%)后脱离核心的发生率，而FBK显示出最高的核心材料骨折百分比，大多数骨折发生在CDC(57%)。MTP合并CNB后骨折最为突出。由于冠状位的脱层，冠状位保留特征的存在并不能保证核心材料强度的增加。

The condylion-gonion-menton angle (CoGoMe^) is commonly used as a pre-treatment indicator of responsiveness in Class II patients treated with functional appliances. The distribution of this angle in the Caucasian population is still unknown. This study aimed to determine the distribution of the CoGoMe^ and its relationship with age, sagittal jaw relationship (ANPg^), and mandibular inclination (SN^GoGn) in patients from Southern Italy. The sample included 290 subjects (median14 years of age; Interquartile range, IQR, 12–17) with lateral cephalograms taken before the orthodontic treatment. The distribution of the CoGoMe^ was assessed with the Shapiro–Wilk test, and the differences according to the ANPg^ and the SN^GoGn were estimated using one-way ANOVA. Linear regression analysis was performed to evaluate how the CoGoMe^ varied according to age. The statistical significance was set at P < 0.05. The results showed that the CoGoMe^ was normally distributed (P = 0.290) with a mean value of 127.2° ± 7.7°. The distribution of the CoGoMe^ in groups with different SN^GoGn angles was significantly different (P < 0.001). These angles showed a positive association (Beta coefficient B = 0.6; 95% CI: 0.51, 0.67; P < 0.001). In growing patients, the CoGoMe^ decreased every year by 0.6° (B = −0.6; 95% CI: −1.05, −0.12; P = 0.014). In conclusion, the CoGoMe^ was associated with mandibular inclination and could be considered to be a predictor of vertical growth patterns.

Background: The effects of publishing case reports on journal impact factor and their impact on future research in pediatric dentistry has not been clearly evaluated yet. Aim. To assess the relevance and role of case reports in pediatric dentistry. Methods: A systematic review (PROSPERO registration number: CRD42018108621) of all case reports published between 2011 and 2012 in the three major pediatric dentistry journals was performed manually. Data regarding citations of each report were acquired from the Institute for Scientific Information database available online. The authors analyzed information regarding citations (number, percentage, and mean) received by each case report and considered their relation with the 2013 journal impact factor. Results: Case reports accounted for almost sixteen per cent of all articles published between 2011 and 2012. The citation rate of case reports was generally low and the highest mean citation was 0.5. This review revealed that 6 (9.52%) case reports had at least 5 citations and that the majority of the citing articles were also case reports (27.78%) or narrative reviews (25%). Conclusions: The publication of case reports affected the journal impact factor in a negative way, this influence is closely related to the percentage of the published case reports. Case reports about innovative topics, describing rare diseases, syndromes, and pathologies were more frequently cited.

Pulmonary nodules are frequently considered to be a metastatic disease or primary lung tumors in oral cancer patients. We present a case of pulmonary cryptococcosis in a 68-year-old man with oral and lung cancer. This lung cancer was treated with thoracoscopic resection of the right inferior lobe and mediastinal lymph node dissection. Lower gingival cancer was treated with a mandibulectomy, neck dissection, and reconstruction after chemoradiotherapy. A 20 mm cavitary nodule appeared at the left lung S6 one-month after surgery, during post-operative computed tomography. Thoracoscopic partial resection of the left inferior lobe was performed under the suspicion of lung metastasis. Pathology results revealed a pseudo-epithelial granuloma with necrosis and many yeast-shaped fungi with capsules. A pathological diagnosis of Cryptococcus infection was made. The patient was prescribed the antifungal agent fosfluconazole, which was administered intravenously for 1 week and intraoral fluconazole for 12 months. No recurrence of the Cryptococcus infection has been noted after 1.5 years.

Introduction: Recreational and sport activities, traffic accidents and human behaviour represent the main causes of trauma in young people. Case presentation: This report describes a case of a 15.2-year-old male who suffered uncomplicated crown fracture and avulsion of tooth 11 and uncomplicated crown fracture of tooth 21 due to a bicycle accident. Tooth 11 was dry stored and it was replanted 18 h after the trauma. The root was planed to remove the necrotic periodontal tissue, the pulp was extirpated before replantation and a flexible splint was applied to tooth 13 to tooth 23 for 3 weeks. A replacement root resorption of replanted tooth was suspected at the 3-month radiographic control and suffered a dramatic increase later; minimal infraocclusion, about 1 mm, was observed due to its ankylosis. Sixteen years after the trauma the patient was scheduled for an orthodontic and implanto-prosthetic rehabilitation. Conclusion: Delayed replantation usually has a long-term poor prognosis, so it is very important to promote awareness regarding emergency management modalities in dental traumatology especially among parents, school teachers, and coaches that are usually present at the site of the accident.

Tooth 11 was dry stored and it was replanted 18 h after the trauma. The root was planed to remove the necrotic periodontal tissue, the pulp was extirpated before replantation and a flexible splint was applied to tooth 13 to tooth 23 for 3 weeks. A replacement root resorption of replanted tooth was suspected at the 3-month radiographic control and suffered a dramatic increase later; minimal infraocclusion, about 1 mm, was observed due to its ankylosis. Sixteen years after the trauma the patient was scheduled for an orthodontic and implanto-prosthetic rehabilitation. Conclusion: Delayed replantation usually has a long-term poor prognosis, so it is very important to promote awareness regarding emergency management modalities in dental traumatology especially among parents, school teachers, and coaches that are usually present at the site of the accident.","PeriodicalId":47284,"journal":{"name":"Open Dentistry Journal","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74483391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peri-implantitis (PI) is an inflammatory disease of peri-implant tissues, it represents the most frequent complication of dental implants. Evidence revealed that microorganisms play the chief role in causing PI. The purpose of our study is to evaluate the cleaning of contaminated dental implant surfaces by means of the Q-switch Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser and an increase in temperature at lased implant surfaces during the cleaning process. Seventy-eight implants (titanium grade 4) were used (Euroteknika, Sallanches, France). Thirty-six sterile implants and forty-two contaminated implants were collected from failed clinical implants for different reasons, independent from the study. Thirty-six contaminated implants were partially irradiated by Q-switch Nd:YAG laser (1064 nm). Six other contaminated implants were used for temperature rise evaluation. All laser irradiations were calibrated by means of a powermetter in order to evaluate the effective delivered energy. The irradiation conditions delivered per pulse on the target were effectively: energy density per pulse of 0.597 J/cm2, pick powers density of 56 mW/cm2, 270 mW per pulse with a spot diameter of 2.4 mm, and with repetition rate of 10 Hz for pulse duration of 6 ns. Irradiation was performed during a total time of 2 s in a non-contact mode at a distance of 0.5 mm from implant surfaces. The parameters were chosen according to the results of a theoretical modeling calculation of the Nd:YAG laser fluency on implant surface. Evaluation of contaminants removal showed that the cleaning of the irradiated implant surfaces was statistically similar to those of sterile implants (p-value ≤ 0.05). SEM analysis confirmed that our parameters did not alter the lased surfaces. The increase in temperature generated at lased implant surfaces during cleaning was below 1 °C. According to our findings, Q-switch Nd:YAG laser with short pulse duration in nanoseconds is able to significantly clean contaminated implant surfaces. Irradiation parameters used in our study can be considered safe for periodontal tissue.

The prevalence of malocclusion and a need for orthodontic treatment is high. Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. The aim of this study was to investigate the self-reported changes in oral hygiene habits among adolescents receiving orthodontic treatment. A cross-sectional study of 291 patients aged 10–17 years (mean (M) = 12.98; standard deviation (SD) = 2.36) was conducted in the Department of Orthodontics, Lithuanian University of Medical Sciences (LSMU) Hospital (Kaunas, Lithuania) during the fall semester (October–January) of the 2017/2018 study year. An anonymous self-administered questionnaire covered background information, experience of orthodontic treatment, oral hygiene habits and the seeking of professional dental care. Statistical data analysis was performed using SPSS version 22. To establish relationships between categorical variables, Chi-squared tests (χ2) were used. A p-value ≤ 0.05 was set to indicate statistically significant difference. The univariate logistic regression analysis evaluated the probability of an event given a certain risk indicator, including odds ratio (OR) and its confidence interval (95% CI). Associations were found between the usage of auxiliary measures (OR = 1.797 (1.118–2.887), p = 0.015), tongue cleaning (OR = 1.712 (1.059–2.767), p = 0.028), mouth rinsing after meals (OR = 1.707 (1.048–2.781), p = 0.032) and experience of orthodontic treatment, respectively. More orthodontic patients underwent professional oral hygiene regularly than non-orthodontic patients (p = 0.024). More patients with fixed orthodontic appliances reported significantly changed oral hygiene habits, while more orthodontic patients with removable appliances did not change their oral hygiene habits.
