Poor glycemic control impairs oral health in children with type 1 diabetes mellitus - a systematic review and meta-analysis.

Objective: There are more than one million children and adolescents living with type 1 diabetes mellitus, and their number is steadily increasing. Diabetes affects oral health through numerous channels, including hyposalivation, immune suppression, and the inflammatory effect of glycation end-products. However, patients with type 1 diabetes must follow a strict sugar free diet that is proven to be carioprotective.

A novel image processing procedure for the quantitative evaluation of dental enamel prism arrangement.

Enamel prism is the main microstructural unit of mammalian enamel which composed of hundreds of bioapatite nanocrystals. Prism structure plays a key role in the excellent mechanical performance of dental enamel during millions of chewing cycles without significant remodeling. Thus, quantitative understanding of prism architecture is of utmost importance for biomechanical materials design.

We conducted a meta-analysis and systematic review to investigate the efficacy of chitosan-containing chewing gums, and to test their inhibitory effects on . The systematic search was performed in three databases (Cochrane Library, EMBASE, and PubMed) and included English-language randomized-controlled trials to compare the efficacy of chitosan in reducing the number of . To assess the certainty of evidence, the GRADE tool was used.

[The role of probiotics in oral health.].

Introduction: The World Health Organization defines probiotics as: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host." Probiotics maintain the balance of the normal intestinal flora and prevent the proliferation of pathogenic bacteria. Its therapeutic use in oral health is increasing.

Preoperative HbA1c and Blood Glucose Measurements in Diabetes Mellitus before Oral Surgery and Implantology Treatments.

Diabetes mellitus has become a worldwide epidemic and is frequently accompanied by a number of complications proportional to the duration of hyperglycemia. The aim of this narrative review is to assess the most up-to-date guidelines on DM provided by both diabetes and dental associations. Furthermore, to gather evidence on the uni/bidirectional relationships of elevated HbA1c levels on dental surgery, implantology, bone augmentation, and periodontology and to demonstrate the importance of measuring HbA1c levels before invasive dental treatments.

Oral Health Status of Children Living with Type 1 Diabetes Mellitus.

Background: Diabetes is a well-known predisposing factor for oral diseases, so prevention in an early age is mandatory.

Objective: To provide oral screening for children living with type 1 diabetes. We aimed to investigate the oral and general health indexes of T1DM children and compare these data to healthy siblings and controls.

[Root-crown ratios of permanent teeth in healthy and young Hungarian, German, and Japanese populations].

Unlabelled: Összefoglaló. Bevezetés: A maradó fogak gyökér-korona arányának meghatározása nagy jelentőséggel bír a fogászati kezelési terv kialakításában és későbbi módosításában. Célkitűzés: Egészséges magyar, német és japán fiatalok maradó fogai gyökér-korona arányának meghatározása és összehasonlítása.

Patterns of Facial Profile Preference in a Large Sample of Dental Students: A Cross-Sectional Study.

The objective of this study was to explore dental students' facial profile preferences in a large sample of students. Nine hundred and nineteen dental students of four dental schools were involved. As part of a larger study on dentofacial esthetics, six photo series consisting of one unaltered and four altered variants of the same female profile were distributed among the students.

Magnesium incorporation into primary dental enamel and its effect on mechanical properties.

Cross-sectional study of sound primary dental enamel revealed hardness zonation and, in parallel, significant change in the Mg content below the prismless layer. Mg content is known to play an important role in enamel apatite biomineralization, therefore, Mg ion exchange experiments were carried out on the outer surface of sound primary molars and on reference abiogenic Ca-phosphates using MgCl solution. Effects of Mg incorporation on crystal/particle size, ionic ratio and morphology were compared and the observed changes were explained by parallel diffusion and dissolution/reprecipitation processes.

Dentofacial mini- and microesthetics as perceived by dental students: A cross-sectional multi-site study.

Background: How dental education influences students' dental and dentofacial esthetic perception has been studied for some time, given the importance of esthetics in dentistry. However, no study before has studied this question in a large sample of students from all grades of dental school. This study sought to fill that gap.

Maternal-related factors in the origin of isolated cleft palate-A population-based case-control study.

Objects: Isolated cleft palate (CPO) is the rarest form of oral clefting affecting 1-25 per 10 000 newborns worldwide. There is increasing evidence for the different pathogenetic backgrounds of CPO and cleft lip with or without cleft palate. The role of environmental factors in the origin of non-syndromic and syndromic CPO is unclear in most patients.

Licensing the first reduced, 6 µg dose whole virion, aluminum adjuvanted seasonal influenza vaccine - A randomized-controlled multicenter trial.

Introduction: Shortages of vaccine supplies repeatedly occur, limiting our abilities to prevent influenza. Therefore, increasing production volume remains a priority. The presently licensed seasonal influenza vaccines contain 15 µg of viral hemagglutinin per strain in adult, and up to 60 µg in elderly patients.

[Incidence of type 2 diabetes among oral cancer patients in Hungary].

Introduction: Data proves that Hungary has a leading role in the statistics of oral cancer and patients living with type 2 diabetes.

Aim: Our aim was to understand the statistical correlation between oral cancer and metabolic disorder (diabetes mellitus and impaired fasting glucose) due to the valuable data from the Semmelweis University.

Method: We analyzed the data of 835 patients diagnosed with malignant oral cancer and 587 tumor-free control patients.

Effects of variable attachment shapes and aligner material on aligner retention.

Objective: To evaluate the retention of four types of aligners on a dental arch with various attachments.

Materials And Methods: For this study, three casts were manufactured, two of which contained attachments (ellipsoid and beveled), and one without any attachments to serve as a control. Four types of aligners were thermoformed: Clear-Aligner (CA)-soft, CA-medium, and CA-hard, with various thicknesses, and Essix ACE.
