The essential oil of turpentine and its major volatile fraction (alpha- and beta-pinenes): a review.
2010
This paper provides a summary review of the major biological features concerning the essential oil of turpentine, its origin and use in traditional and modern medicine. More precisely, the safety of this volatile fraction to human health, and the medical, biological and environmental effects of the two major compounds of this fraction (alpha- and beta-pinenes) have been discussed.
Clinician-related factors behind the decision to extract an asymptomatic lower third molar. A cross-sectional study based on Spanish and Portuguese d…
2017
Background: Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians’ training and professional experience. Material and Methods: A survey consisting of 15 cases of asymptomatic lower third molars was emailed to Portuguese and Spanish dentists. The clinicians were asked to assess the level of difficulty of the extractions and to make a reasoned recommendation based on the panoramic radiographs, gender and age of the patients. Results: 381 cl…
Indications of the extraction of symptomatic impacted third molars. A systematic review
2021
Background A literature review was made to determine when third molar (3M) extraction is recommended in symptomatic patients and when it is not recommended. Material and methods A Medline (PubMed) and EMBASE search was made for articles related to indications for the extraction of 3Ms, published in the last 10 years and up until September 2018. Results The electronic search yielded 175 articles. After eliminating duplicates, a total of 173 articles were subjected to review of the title and abstract. Only 19 studies were finally included in the systematic review. There was a well documented increase in morbidity associated to impacted 3Ms (non-restorable caries, fracture, infection, periodon…
Patient morbidity after impacted third molar extraction with different flap designs. A systematic review and meta-analysis
2020
Background To review the literature on the effect of different surgical flaps upon patient morbidity (pain perception, trismus, swelling and osteitis) after impacted third molar extraction. Material and Methods An electronic and complementary search of main databases and grey literature was performed up to January 2019 to retrieve randomized clinical trials. The Cochrane risk of bias assessment tool was used for methodological appraisal. A random-effects meta-analysis was conducted of pain perception and trismus. Results From the initially 1314 screened studies, only 11 were included in the qualitative synthesis, and 5 in the meta-analysis. There were no statistically significant difference…
Approaches used to care for carious primary molars among pediatric dentists and general dental practitioners in Saudi Arabia
2018
Background The aim of this cross sectional study was (1) to identify and compare the approaches which are used to care for carious primary molars between pediatric dentists (PDs) and general dental practitioners (GDPs) in Saudi Arabia and (2) to evaluate the knowledge level of the most appropriate treatment decisions for both groups with regard to caries in primary molars and its relation with demographic variables. Material and Methods A random sample of 600 GDPs and all registered PDs (n = 100) in the Saudi dental society in 2016 were emailed a two part questionnaire; the first part included questions about demographic data and the second part investigated knowledge of the participants of…
Long-standing oral ulcers: proposal for a new `S-C-D classification system’
2008
Persistent oral ulcers and erosions can be the final common manifestation, sometimes clinically indistinguishable, of a diverse spectrum of conditions ranging from traumatic lesions, infectious diseases, systemic and local immune-mediated lesions up to neoplasms. The process of making correct diagnosis for persistent oral ulcers still represents a challenge to clinicians. Major diagnostic criteria should include the clinical appearance of both ulcer and surrounding non-ulcerated mucosa, together with the evaluation of associated signs and symptoms, such as: number (single or multiple), shape, severity of the ulcer(s), conditions of remaining mucosa (white, red or with vesiculo-bullous lesio…
Adverse Reactions to Anticancer Drugs in the Oral Cavity
2018
The development, testing, and adoption into clinical practice of anticancer medications have revolutionized cancer care over the past decades. A better understanding of the biology of cancer has translated into development of novel systemic agents, as well a more effective use of older chemotherapy agents. As a consequence, cancer mortality continues to decrease. However, greater cure and disease control rates come at a price of an increased risk of adverse effects, which often affects the mouth and related structures including the oral mucosa, salivary glands, jawbones, and cranial nerves. Oral mucositis, hyposalivation, dysgeusia, and osteonecrosis of the jaw (ONJ) are some examples of th…
Does chlorhexidine improve outcomes in non-surgical management of peri-implant mucositis or peri-implantitis? : a systematic review and meta-analysis
2019
Background With greater number of implants being placed in clinical practice, incidence of peri-implant diseases are on the rise. It is not known whether chlorhexidine (CHX) improves outcomes in the management of peri-implant diseases. The aim of this systematic review and meta-analysis was to evaluate the role of CHX in improving outcomes with non-surgical management of peri-implant mucositis and peri-implantitis. Material and Methods An electronic search of PubMed, Scopus, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases up to 1st August 2019 was carried out to search for studies evaluating the efficacy of CHX for non-surgical management of peri-implant disea…

During the early months of the COVID-19 pandemic, there was an unusually high submission rate of scholarly articles. Given that most academics were forced to work from home, the competing demands for familial duties may have penalized the scientific productivity of women. To test this hypothesis, we looked at submitted manuscripts and peer review activities for all Elsevier journals between February and May 2018-2020, including data on over 5 million authors and referees. Results showed that during the first wave of the pandemic, women submitted proportionally fewer manuscripts than men. This deficit was especially pronounced among more junior cohorts of women academics. The rate of the pee…
Smarter, not harder.
2017
The purpose of this investigation was to compare and determine the relevance of the morphological characteristics and variability of running speed parameters (stride length and stride frequency) between Usain Bolt’s three best 100 m performances. Based on this, an attempt was made to define which factors determine the performance of Usain Bolt’s sprint and, therefore, distinguish him from other sprinters. We analyzed the previous world record of 9.69 s set in the 2008 Beijing Olympics, the current record of 9.58 s set in the 2009 Berlin World Championships in Athletics and the O lympic record of 9.63 s set in 2012 London Olympics Games by Usain Bolt. The application of VirtualDub Programme …
