Background: High incidence of fracture of all-ceramic crowns may compromise the clinical outcome and is a source of hassle for both patients and dentist. Objective: The objective of the present review was to identify reasons for high ceramic fracture or chipping and to minimize these incidents in dental settings. Methods: The final search strategy was executed on Medline via OvidSP, PubMed, and Web of Knowledge. Studies meeting the following inclusion criteria were included in the current review. (1) Literature in English language only, (2) in vitro studies, (3) studies providing evidence on ceramic fracture, and (4) studies only related to indirect restoration and ceramics. Moreover, the exclusion criteria were based on (1) articles other than English, (2) studies reporting direct restoration, (3) any non–peer-reviewed gray literature, and (4) studies discussing fracture other than ceramic material. Results: From the initial search strategy, 101 studies were retrieved from different databases. A total of 3 studies were scrutinized through other resources. Following duplicate removal (n = 24), 80 studies were screened for the title and abstract. Moreover (n = 49) studies were shortlisted for full text and review. Following review and discussion in the final result, only 26 studies were included. Conclusions: Many improvements in the material, its fabrication process, and surface treatments can reduce the incidence of fracture within the material.

Background: Natural products are commonly used for treating health problems. These products may be associated with adverse events, which are defined as "noxious and unintended response to a medicinal product" by the European Medicine Agency. Objectives: To identify studies describing at least one adverse event (or with potential to promote an adverse event) related to the use of natural products, as well as to describe the involved product(s) and adverse event(s). Methods: A pre-systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Keywords: "natural product(s)" and ["adverse drug reaction(s)" or "adverse effect(s)"]. Screened databases: PubMed, SciELO, DOAJ and Google Scholar. Inclusion criteria: papers describing at least one adverse event associated with the use of natural products and published between 2017 and 2019. Exclusion criteria: Repeated studies, reviews and papers written in other languages than English, Portuguese, French or Spanish. Results: 104 studies were identified (20 PubMed; 0 SciELO; 2 DOAJ; 82 Google Scholar), but only 10 were selected (4 PubMed and 6 Google Scholar): 1 in-vitro study; 2 non-clinical studies, 1 study reporting in-vitro and clinical data and 5 studies were cases reports. Globally, 997 reports of adverse drug reactions with natural products were identified, mainly non-severe cases. Conclusion: Since a limited number of studies was found, we conclude that adverse events due to natural products may be underreported, or natural products may have a good safety profile. This review contributes for assuring the safety of natural products consumers, by evaluating the knowledge/information on the potential adverse events and interactions of these products.

Data Source

Objective. To systematically review the effectiveness of intervention studies promoting diet and physical activity (PA) in nurses. Data Source. English language manuscripts published between 1970 and 2014 in PubMed, Scopus, CINAHL, and EMBASE, as well as those accessed with the PICO tool, were reviewed. Study Inclusion and Exclusion Criteria. Inclusion criteria comprised (1) nurses/student nurses working in a health care setting and (2) interventions where PA and/or diet behaviors were the primary outcome. Exclusion criteria were (1) non–peer-reviewed articles or conference abstracts and (2) interventions focused on treatment of chronic conditions or lifestyle factors other than PA or diet in nurses. Data Extraction. Seventy-one full texts were retrieved and assessed for inclusion by two reviewers. Data were extracted by one reviewer and checked for accuracy by a second reviewer. Data Synthesis. Extracted data were synthesized in a tabular format and narrative summary. Results. Nine (n = 737 nurses) studies met the inclusion criteria. Quality of the studies was low to moderate. Four studies reported an increase in self-reported PA through structured exercise and goal setting. Dietary outcomes were generally positive, but were only measured in three studies with some limitations in the assessment methods. Two studies reported improved body composition without significant changes in diet or PA. Conclusions. Outcomes of interventions to change nurses’ PA and diet behavior are promising, but inconsistent. Additional and higher quality interventions that include objective and validated outcome measures and appropriate process evaluation are required.

Anxiety is a feeling of helplessness, and worry about things that are not clear, as well as a comprehensive feeling that something bad is going to happen. Anxiety is experienced subjectively and communicated interpersonally, at the same time feelings of anxiety are a necessary survival instinct. The Neuro-Linguistic Programming (NLP) is a communicative approach employs a positive view of anxiety and how it can help shape life changes, and that is the topic of this article. This research method uses a Systematic Literature Review, investigating Garuda, Pubmed, ScienceDirect, and Proquest, using boolean for keyword neurolinguistics programming (NLP) and anxiety. The inclusion criteria used were Indonesian and English language articles written within the last 5 years (from 2015 until 2020). The exclusion criteria used by the article were abstract writing style, inaccessible, or lacking national accreditation. Articles were tested with Critical Appraisal Tools. The studies indicate that good communication using NLP can help reduce anxiety and can promote changes in a person’s behavior patterns. There are several NLP techniques including sensory acuity, reframing, anchoring, rapport, and pacing, and leading. NLP can improve knowledge, skills and attitudes, communication skills, self-management, mental health, reduce work stress, and self-efficacy.   Keywords: Anxiety, Neuro-Linguistic Programming, NLP

Abstract Aim The aim of this study was to investigate the influence of three different thicknesses of In-Ceram core on the load at fracture of all-ceramic crowns. Methods and Materials Thirty standardized crown-shaped nickel-chromium alloy dies were fabricated using a milling machine. Twenty dies were prepared with a 1 mm shoulder for Groups A and B. The only difference in the ten dies used for Group C was a smaller 0.5 mm lingual shoulder. The thicknesses of In-Ceram were 0.5 mm, 1.5 mm, and 0.75 mm for Groups A, B, and C. All all-ceramic crowns were fabricated in accordance with the manufacturer's instructions. After cementation of the crowns, their fracture resistance was tested with a universal testing machine. The load was directed to a point located 3 mm from the lingual aspect of the incisal edge at 30 degrees to the long axis of each specimen until catastrophic failure occurred. Results The mean loads at fracture for Groups A, B, and C were 1117±388 N, 2083±385 N, and 1439±368 N, respectively. No statistically significant difference in load at fracture between Groups A and C was found (p>0.05). However, the differences were statistically significant between Groups A and B (p<0.001) and Groups B and C (p<0.001). Conclusion Under the guidelines of this study, increasing the thickness of the In-Ceram core increased the fracture resistance of the all-ceramic crowns. Clinical Significance The sufficient thickness of the In-Ceram core of all-ceramic crowns is an important factor in fracture resistance. Therefore, dental practitioners should be careful in patient selection; if the horizontal overlap of a tooth to be restored is too limited, then all-ceramic crowns may not be a feasible option.

Alveolar Osteitis

Background: Dry socket is one of the most common post-extraction complications with its incidence reaching up to 30% after impacted third molar extractions. In spite of its high incidence, there is no established treatment for the condition. Objectives: To investigate how efficient different management methods of Alveolar osteitis are, in regards to pain relief, healing process and reduction of the incidence. Materials and Methods: A literature search of “PubMed-MEDLINE” database was conducted using the keywords “dry socket management”, “alveolar osteitis”, “fibrinolytic alveolitis”, “post-extraction complications”. The inclusion criteria were clinical studies, case reports, reviews and human studies, related to alveolar osteitis published from 2011-2016, written in English language. The exclusion criteria were animal studies, studies that discussed other post-extraction complications, and in any other languages than English. Results: 63 articles were found and only 31 were reviewed. 18 out of 31 articles were included in the results, after reading the full text, due to lack of significant results in the rest of the articles. Out of these there were 12 clinical studies, 3 systematic reviews and 1 retrospective study. Conclusion: It was concluded that there is no specific management that could be rated as the best to treat dry socket, due to the lack of evidence to support the use of one management over the other, although there are many options that can help manage it and have proved to be highly effective recently and until today.
