Alternative Conservative Approach for Tooth Build-Up in Patients with Special Healthcare Needs

Purpose: The success of an artificial crown mainly depends on the biomechanical factors such as bonding capacity of cement between the crown and abutment tooth, and root strength of the abutment tooth. In this case series, we aim to provide insight on the potential use of the cast metal post and cost for patients with intellectual disabilities and severely compromised tooth structure. Material and Methods: The first patient was a 41-year old male with the chief complaint of a dislodged porcelain fused metal (PFM) crown of tooth #20 (mandibular left second bicuspid). The patient was informed about the advantages, disadvantages, and risks of each option. After further consideration and discussion with the parents and the patient, we decided to rebuild the coronal tooth structure with the cast metal post and core and prosthetic restoration with the same crown. Patient satisfaction was measured on the visual analog scale as 10/10. The second case involves a 26-year old female, who presented with a chief complaint of chronic lingering pain on tooth #9. The tooth structure was extensively damaged and un-supportive of the ferrule, therefore, it was decided to build a metal post and core instead of a fiber post. The prosthetic restoration was made with a monolithic zirconia crown and the patient was followed up twice in 6 months and graded the satisfaction as 10/10 on a visual analog scale. Results: The most common type of posts used in dentistry has been cast post and cores in the last decade which generally includes an additional laboratory stage where a custom post is prepared according to the impression taken from the prepared post space. Conclusions: Both the presented cases explain an interesting advantage of restoring a root canal treated tooth with a metal post and core system which implies that in a prefabricated post and core restored tooth failure, a metal post, and core can potentially be the treatment of choice instead of extracting the tooth.

BRAIN GYM EXERCISES: AN APPROACH IN IMPROVING THE PSYCHOLOGICAL PERCEPTION IN GRADUATE STUDENTS

Brain Gym is an academic kinesiological program that is promoted and applied with a consistent learning purpose that aims at enhancing performance such as memory, psychological perception and cognitive skills. The technique requires the participant to communicate with a series of activities that help the body to understand the primary behaviour and learn how to coordinate the brain and entire body. Brain Gym activities includes of 26 basic motions, which are believed to improve perception and stimulates brain hemisphere by neural re-modelling to facilitate whole brain learning. By ways of balancing both the side of brain, behavioural difficulties, social and intellectual burdens are expected to be reduced. This study aims to improve the psychological perception and decrease depression in the undergraduate physiotherapy students. Here's an idea we suggest to check the psychological perception with brain gym intervention and the duration for practices comprises of three days a week session, duration of 25 minutes, which is completed in one hour. The study design is of pre- post type with simple randomized sampling. Before the treatment the mean stress showed a mean score of 33.87, anxiety showed a mean score of 32.43, depression showed a mean score of 32.34; an improvement was seen after the treatment where the mean score was 18.42, 17.26, 19. 46. The final mean difference was 43.49±17.33 and t -value 30.42 (p=0.0001,S). The data analysis shows that after the Brain Gym Activity intervention there was marked reduction in the score of DASS. The participants involved in the study showed significant improvement in their psychological perceptions.

Commenting on Brand Posts during a Crisis: The Relationship between Context-Induced Moods and Brand Message Processing across Three Social Media Platforms

Within the context of COVID-19, this study examines the relationship between context-induced moods and consumers’ responses to two different types of brand posts on social media: profit-driven posts and public-driven posts. Using both social media data (24,578 user comments on 14 brand posts on Facebook, Instagram, and Twitter) and survey data (356 subjects recruited from Amazon.com’s Mechanical Turk), we found that across all three social media platforms (i.e., Facebook, Instagram, and Twitter), the more negative mood one was in when using a social media platform during the pandemic, the more likely one would leave a comment to praise the company endorser of the public-driven post (comment type 5) as opposed to leaving a comment to discuss serious issues, shedding light on the prediction of negative-state relief model. By contrast, across all three social media platforms, there is no relationship between context-induced moods and types of comments people leave on a profit-driven brand post. We provide theoretical, practical, and methodological implications for future research.

Blooming artifact reduction using different cone-beam computed tomography software to analyze endodontically treated teeth with intracanal posts.

The appearance of high-density root obturating materials, such as gutta-percha and intracanal posts, on cone-beam computed tomography (CBCT) scans is substantially different from that seen in the specimen. This study evaluated the effectiveness of different CBCT software in the reduction of blooming artifacts when examining teeth with intracanal posts. The sample included 42 human single-rooted teeth with two types of posts: G1 - low-fusion alloy posts; G2 - gold alloy posts. CBCT scans were obtained using two scanners, PreXion 3D Elite® and Carestream 9000C 3D®. First, the posts were measured using a digital micrometer (standard reference, control). Post diameters were determined using the Blooming Artifact Reduction (BAR) tool of the e-Vol DX software and of the PreXion3D Image Analysis System. Statistical data were evaluated using the van Der Waerden nonparametric analysis of variance and, after that, normalized data were analyzed using the Tukey test. The level of significance was set at α=5%. There were no significant differences (p>0.05) between the diameters of intracanal posts on the CT scans when the e-Vol DX was used, or when these results were compared with those obtained using a micrometer. There were significant differences in post diameters determined using the PreXion3D Image Analysis System when compared with the e-Vol DX and the micrometer values (p<0.05). The use of the e-Vol DX BAR filter eliminated blooming artifacts. There were no dimensional changes in the CBCT images of the low-fusion and gold alloy intracanal posts using the e-Vol DX BAR filter.

Efficacy of Different Dentin Posts for the Treatment of Primary Anterior Teeth (An In vitro study)

ABSTRACTIntroduction: Early childhood Caries is a distressing situation for patients andparents and pediatric dentists. Aim: current research was carried out to evaluatefracture resistance and bond strength for different types of dentin posts compared tofiber posts. Materials and Methods: This Current in-vitro study was conducted on48 extracted primary incisors. Samples were split randomly into 4 groups of 12 foreach group. Group-I (fiber posts 6mm length, 1.4mm diameter), Group-II (dentin posts6mm length, 1.4 diameter), Group-III (dentin posts 8mm length, 1.4mm diameter),Group-IV (dentin posts 8mm length, 1.6mm diameter). Each group was furthersubdivided into two subgroups (6 for the Push-Out bond strength test and 6 for thefracture resistance test using Universal Testing Machine). Results: It was observedin the fracture resistance test that, Group III showed the highest fracture resistancemeans (140.678±11.98) followed by Group IV (131.38±7.03), Group-II (94.23±9.84),and finally Group-I that showed the lowest fracture resistance means (80.465±2.82).Push-Out bond strength test revealed that the highest mean value with Group-IV(8.653±1.49), followed by Group-II (6.08±2.25) and Group III (5.67±2.44) have nostatistically significant difference between them, while the lowest mean value was forGroup-I. Conclusions: Dentin posts showed increased fracture resistance and bondstrength more than fiber posts. The use of dentin post as intra-canal retention in primaryanterior teeth possesses the most important advantages over the fiber post. Therefore,biological dentin post is a successful alternative for fiber post.

Algoritma Multinomial Naïve Bayes Untuk Klasifikasi Sentimen Pemerintah Terhadap Penanganan Covid-19 Menggunakan Data Twitter

Currently, the spread of information Covid-19 is spreading rapidly. Not only through electronic media, but this information is also disseminated by user posts on social media. Due to the user text posted is varies greatly, it’s needs a special approach to classify these types of posts. This research aims to classify the public sentiment towards the handling of COVID-19. The data from this study were obtained from the social media application i.e., Twitter. This study uses a derivative of the Naïve Bayes algorithm, namely Multinomial Nave Bayes to optimize the classification results. Three class labels are used to classify public sentiment namely positive, negative, and neutral sentiments. The stage starts with text preprocessing; cleaning, case folding, tokenization, filtering and stemming. Then proceed with weighting using the TF-IDF approach. To evaluate the classification results, data is tested using confusion matrix by testing accuracy, precision, and recall. From the test results, it is found that the weighted average for precision, recall and accuracy is 74%. Research shows that the accuracy of the proposed method has fair classification levels.

The rise of Instagram as a tool for political communication: A longitudinal study of European political parties and their followers

Featuring a longitudinal, structural study of European party and citizen activity on Instagram between 2012 and 2018, this article outlines the overarching changes in the ways that Instagram has been employed for political party communication. Differentiating between populist and non-populist political parties, the results indicate that much like for other platforms such as Facebook, the former category of parties enjoy higher amounts of citizen engagement than their non-populist competitors. Detailing the uses of different types of posts by the two types of political actors, the study provides insights into how political parties have adopted and used Instagram from 2012 and onward.

Influence of social media posts on service performance

PurposeMuch research regarding social media posts and relevancy has resulted in mixed findings. Furthermore, the mediating role of relevancy has not previously been examined. This paper aims to examine the correlating relationship between types of posts made by hotels and the resulting occupancy rates. Then, the mediating role of relevancy is examined and ways that posts can increase/decrease relevancy of the post to potential hotel users.Design/methodology/approachWithin the context of the hotel industry, three studies were conducted – one including hotel occupancy data from a corporate chain – to examine the impact of social media posts on relevancy and intentions to stay at the hotel. Experimental studies were conducted to explain the results of the real-world hotel data.FindingsThe findings show that relevancy is an important mediator in linking social media posts to service performance. A locally (vs nationally) themed post can decrease both the relevancy of a post and the viewer’s intentions to stay at a hotel. This relationship, however, can be weakened if a picture is included with the post, as a visual may increase self-identification with a post.Originality/valueThese results have important theoretical and practical implications as social media managers attempt to find the best ways to communicate to their customers and followers. Specifically, there are lower and upper limits to how many times a hotel should be posting to social media. The data also show many hotels post about local events, such as school fundraisers or a job fair, that can be harmful to stay intentions, likely due to the irrelevant nature of local posts to customers who are likely to stay in a hotel. National posts are seen as more relevant and likely to increase stay intentions, and the inclusion of a picture can help local posts seem more relevant.

Analyses of posts written in online eating disorder and depression/anxiety moderated communities: Emotional and informational communication before and during the COVID-19 outbreak

IntroductionModerated online health communities (OHCs) are digital platforms that provide a means for patients with similar medical conditions to communicate with each other under the supervision of healthcare professionals. AimsTo examine the impact of the COVID-19 outbreak on content and type of posts published in two moderated OHCs – eating disorders and depression/anxiety – by comparing categorizations of posts written before vs. after the lockdown, and about vs. not about the pandemic. MethodsPosts were retrieved from Camoni, the first Israeli medical social network (January-June 2017, March-May 2020). A total of 1475 posts were analyzed. Of them, 802 posts were written before and 680 were written during the first lockdown. Posts were divided into two main categories: informational and emotional, and into fourteen subcategories. ResultsBefore the pandemic, the eating disorders OHC was characterized as primarily emotional (emotional: 66.7%, informational: 45.4%) and the depression/anxiety OHC as primarily informational (emotional: 49.8%, informational: 65.8%) (χ2 = 31.6, p < 0.001). During the lockdown, there was a transition in the eating disorders community, from primarily emotional to primarily informational communication (emotional: 46.1%, informational: 71.7%) (χ2 = 30.3, p < 0.001). In both OHCs, only about one in six posts written during the lockdown was related to the pandemic. There were only minimal differences in subcategorization of posts written before vs. after the outbreak (e.g., searching for medical information was more common during the pandemic: χ2 = 40.9, p < 0.001), as well as about vs. not about the pandemic (e.g., sharing negative emotions was more common when writing about the pandemic: χ2 = 4.1, p = 0.43). ConclusionDuring the first lockdown, people with eating disorders have increased their use of OHCs as sources of informational (as opposed to emotional) support, but the overall impact of the pandemic on the content of posts written in the examined OHCs was minimal, suggesting that OHCs have not changed their function as a valuable means of providing emotional and informational support for people with mental difficulties.

P-OT029. Clinical neurophysiology social media engagement differs between facebook and twitter users

Introduction . In an age where social media is prevalent and long hours are spent browsing through the internet, it is crucial to understand audience engagement. Two of the most common platforms used worldwide are Twitter and Facebook. Both have provided a unique opportunity for the science world; it broadened the horizons for spreading information on current endeavors in the research world. Clinical Neurophysiology and Clinical Neurophysiology Practice, the Official Journals of the International Federation of Clinical Neurophysiology, opened the Twitter and Facebook pages on April 1, 2020. We determined what factors would alter users’ engagement. Methods . We employed a multivariate regression analysis. The tested predictor variables included ‘days elapsed since the opening (range: 1–100)’, ‘posting during weekend’, ‘introduction of a 2020 article’, ‘author interview’, ‘inclusion of guidelines or review article’, ‘COVID19-related information’, ‘number of hashtags’, ‘number of attachments’, ‘presence of colored attachment’, and ‘attachment of movie’. The dependent variable was the proportion of engaged users, defined as the number of link clicks divided by users who saw the post. Results . Posts including author interviews (p < 0.001) and those introducing guidelines/review articles (p = 0.005) independently increased the proportion of engaged Facebook users. Conversely, posts including a larger number of colored attachments (p < 0.001) and those introducing COVID19-related articles (p = 0.007) independently increased the proportion of engaged Twitter users. Conclusion . Different types of posts attracted Facebook and Twitter users. Facebook users were specifically engaged with interview-based posts. Facebook users might be willing to read through lengthy posts to understand the authors’ stories behind the study. In contrast, Twitter users might want to absorb essential information with a glance.

Analysis of endodontic success using a Periapical Index in teeth with different types of intraradicular posts

This randomized clinical trial evaluated the influence of the type of intraradicular posts (glass fiber post or cast metal post) in the success of endodontic treatment in teeth that received single metal-ceramic restoration. The sample consisted of adult patients, who presented for the first time seeking routine dental care at the dental school over a period of 5 years. Seventy-six out of ninety-six teeth that received endodontic treatment and intraradicular post were analyzed, randomly distributed in two groups – glass fiber post (n=38), and cast metal post (n=38). The quality of the endodontic treatment was radiographically evaluated, and the apical status was assessed using the periapical index (PAI). Statistical Analyses were performed to a significance level of 5%. Descriptive analyses were used to characterize the teeth and survival curves were created using the Kaplan–Meier method. The success rate of endodontic treatment was 90.8% (n=69) including glass fiber post and cast post. When appropriate endodontic treatment was performed is possible to conclude that the success of endodontic treated teeth that received posts was not related to the post type.

#facialtraumasurgery: Educational Content of Instagram as a Social Media Source for Facial Trauma Surgery.

With an uprising influence of social media platforms like Instagram during the last decade, medical and healthcare related posts have accumulated majorly. In particular the head and face characterizes and signifies each individual's human character, which may be the reason why numerous posts are shared on social media platforms. The purpose of this investigation was to assess the content associated with facial trauma surgery and evaluate its educational quality.The authors performed a retrospective investigation on 550 Instagram posts by #facialtraumasurgery due to number of "likes," comments, type of post, language, its purpose, and source. Furthermore, posts were evaluated due to their educational quality by 3 examiners of different educational levels.The majority of posts showed 0 to 50 "likes" and 0 to 5 comments in English language. The major post type were single photographs (289; 52.5%), multiple photographs (188; 34.2%), videos (73; 13.3%) and predominantly case reports (233; 42.4%). The source was 322 (58.5%) posts by surgeons, followed by 185 (33.6%) clinic posts. Only 10% to 18% of the posts were rated "excellent." Interrater reliability between all 3 examiners presented a high concordance with 89% (P = 0.000).Our study presents an analysis of quantity and quality of social media content according to facial trauma surgery. It supports the deduction that most of the content on Instagram is shared by patients and unclear sources and thus is limited informative. Nevertheless, influence of social media on medical information is increasing and practitioners have to face its effect on their patients.

Influence of post type on periapical status: a prospective study in a Brazilian population.

This prospective study assessed the effect of post type used to restore endodontically treated teeth in the onset, progression, and remission of periapical lesions. One hundred and forty teeth (92 patients) were endodontically treated and received a glass fiber post or a cast metal post and a final restoration at a University Clinic by undergraduate students. All patients were followed up for a mean period of 5.1 ± 2.2years. Periapical Index (PAI) was used for endodontic assessment. Two calibrated and blind examiners assessed the radiographs. The longevity of the endodontic treatment was analyzed using Kaplan-Meier statistics. Of the included teeth, 67.1% received glass fiber posts while 32.9% received cast metal posts. There were 4 endodontic failures, two glass fiber posts with a PAI = 3 in the baseline and PAI = 4 in the last follow-up, and one PAI = 4 in baseline and last follow-up. One cast metal post-failure was PAI = 4 in the baseline and the last follow-up. After 9.4years, the overall success rate of the endodontic treatment was 97.1% (p = 0.7). The tested posts presented similar endodontic healing. Precautions taken during endodontic therapy, post cementation, and final restoration are more likely to be responsible for the success of endodontic treatment rather than a specific type of post. Clinical relevance The type of post is not related to the success of the endodontic treatment.

Social media marketing for businesses: Organic promotions of web-links on Facebook

The effectiveness of social media marketing is a topic of great interest for researchers as well as marketers. To enrich the literature regarding the effectiveness of various types of posts with a web-link, we designed and conducted an experiment on Facebook (FB). This experiment was conducted in a real business environment, through the FB fanpage of a Polish e-commerce store. The observations were analyzed using multiple linear regression and metrics adapted to this experiment from the literature. The results show that a web-link placed in the comments of an FB post, instead of the caption, is more lucrative. It is also shown that, based on the aims of the campaign, such metrics can give valuable information about the optimal time for posting, as well as the interval between posts.

Classifying Reasonability in Retellings of Personal Events Shared on Social Media: A Preliminary Case Study with /r/AmITheAsshole

People regularly share retellings of their personal events through social media websites to elicit feedback about the reasonability of their actions in the event's context. In this paper, we explore how learning approaches can be used toward the goal of classifying reasonability in personal retellings of events shared on social media. We collect 13,748 community-labeled posts from /r/AmITheAsshole, a subreddit in which Reddit users share retellings of personal events which are voted upon by community members. We build and evaluate a total of 21 machine learning models across seven types of models and three distinct feature sets. We find that our best-performing model can predict the reasonability of a post with an F1 score of .76. Our findings suggest that features derived from the post and author metadata were more predictive than simple linguistic features like the post sentiment and types of words used. We conclude with a discussion on the implications of our findings as they relate to sharing retellings of personal events on social media and beyond.

Artificial intelligence (AI) comparison of social media-based patient-reported outcomes of PD-1, BRAF, and CTLA-4 inhibitors for melanoma treatment.

e21572 Background: Due to side effects and adverse psychosocial factors, there can often be a disconnect between clinical impression and the patient perspective of treatment. Melanoma patients frequently use social media to discuss their disease sentiments and outcomes, providing a window into patient insight, otherwise not readily attainable. We analyzed publicly available full text posts on multiple social media platforms concerning melanoma treatments PD-1 inhibitors (pembrolizumab/Keytruda, nivolumab), BRAF inhibitors (dabrafenib, vemurafenib), and CTLA-4 inhibitor (ipilimumab/Yervoy) associated with Patient Global Impression of Change (PGIC) terms to compare and identify patient burden. Methods: Millions (12,599,313) of publicly available online social media text data were extracted and run through Brandwatch Artificial Intelligence-powered database and machine learning algorithm to categorize treatment-specific posts with PGIC terms associated with sentiment. Results: Out of 52,962 posts related to a select list of melanoma treatments, we identified Keytruda (6,080), nivolumab (1,614), dabrafenib (529), vemurafenib (329), and ipilimumab (1715) posts. The top ten types of posts by volume for each treatment were predominantly positive for PGIC terms (improving, well, progress) while being associated with negative emotions (fear and sadness). Patient-perceived better treatments were associated with decrease fear. PD-1 inhibitor Keytruda displayed markedly less fear (56.9%) with a very high positive PGIC (92.3%) in comparison with PD-1 inhibitor nivolumab with decreased positive PGIC (78.0%) and increased fear (81.6%). Likewise, this patten was discovered for the BRAF inhibitors and CTLA-4 inhibitor, albeit less distinct: dabrafenib (positive PGIC 86.4%, fear 71.9%), vemurafenib (positive PGIC 78.0%, 81.6%), ipilimumab (positive PGIC 75.0%, fear 79.3%). Conclusions: Our initial results indicate that despite patients reporting good outcomes from melanoma treatment, they remain fearful. Nonetheless, a trend is identified between patient-perceived better treatment and decreased patient fear. This analysis can help bridge the gap of understanding patient perspective and provides an indication for translation into more effective clinical and pharmaceutical response.

Silanes formulated with thio-urethanes for adhesive bonding of fiberglass posts to root canal

The aim of this study was to evaluate the push out test strength of conventional or anatomical fiberglass posts treated with experimental silanes formulated with thio-urethane oligomers. In the bovine teeth endodontic treatment were used conventional fiberglass posts or anatomical fiberglass posts customized with Filtek Z250 resin composite layer modeling the anatomy of the root canal. The roots were randomly divided into 8 groups (n = 10): CP-RX (Control); CP-HDDI; CP-HDMI; CP-BDI; AP-RX (Control); AP-HDDI; AP-HDMI; and AP-BDI(*). Slices of each root third were subjected to the push out test and failure pattern evaluation (%). Marginal microleakage was observed in root slices submitted to 2% methylene blue solution (%). Push out test strength data were statistically evaluated using Core Team R Program (Language and environment for statistical computing - Foundation for Statistical Computing, Austria) at a significance level of 5%. Results showed that the bond strength varied for each root third as function of the fiberglass post types used (**). For the conventional posts, CP-HDMI and CP-BDI presented higher and significantly similar strengths at the cervical third. CP-HDDI, CP-HDMI and CP-BDI demonstrated higher and significantly similar strengths at the middle third, and CP-HDMI and CP-BDI presented higher and significantly similar strengths at the apical third. For the anatomical posts, AP-RX presented significantly higher strength at the cervical third; AP-RX, AP-HDDI, AP-HDMI and AP-BDI demonstrated greater and significantly similar strengths at the middle third, and AP-RX, AP-HDDI and AP-HDMI showed higher and significantly similar strengths at the apical third. For different post types as function of each silane, AP-RX, CP-HDMI, and CP-BDI had significantly higher strengths at the cervical third; AP-RX, CP-HDMI and CP-BDI displayed significantly higher strengths at the middle third, and CP-HDMI and CP-BDI had significantly higher strengths at the apical third. Mixed failures predominated and the microleakage scores varied between 3 (up to 2/3) and 4 (+2/3). The results showed positive effect of the experimental silanes composed by thio-urethane oligomers in all situations analyzed. Different values in the adhesion of fiberglass posts in relation to experimental silanes were observed, as well as its relation to adhesion in the root thirds. Mixed failures predominated and the microleakage showed similar values among root regions.
